13 Chapter 1 Introduction Although one of the most significant equipments in a Soil Mechanics laboratory is the triaxial apparatus, one may easily realise that a pressure distribution panel stands next to the apparatus. Its role may not be so obvious, but it is true that such a panel is the heart that keeps the apparatus alive. Almost all triaxial apparatus, either strain or stress controlled use air pressure to apply the confining pressure σ c, the pore pressure u or even the axial stress σ a, via a piston, to the specimen. The cell and pore pressure lines of the triaxial apparatus are usually connected to the pressure panel through plastic, flexible pipes. The panel itself is responsible for the proper pressure distribution. Typical triaxial panels consist of three main parts: The main air pressure source, the distribution lines and the pressure regulators. The pressure source is usually an air-compressor, capable of supplying the panel with the required volume of air pressure. It is usually installed, for safety reasons, in a separate room, away from the panel and the apparatus. Its main specifications are the maximum air pressure capacity, air flow discharge, and volume of compressed air. On the other hand, the distribution lines serve as the main pipelines, which split the air pressure to different regulatorsapparatus. They are usually metal pipes, firmly installed on the panel. Along the pipelines, on-off valves are installed, so as to isolate different parts of the pipeline system at the same time. Analog pressure-vacuum gauges are also installed in the pipelines, to allow for quick indication of pressure-vacuum in the panel. Finally, pressure regulators are installed at the end of the pressure distribution lines, which control the air pressure to be sent to the apparatus pressure lines. The functionality of a pressure panel lies on its capability to supply triaxial apparatus with air pressure. Well designed panels are usually easy to operate, allowing for space among their on-off valves and regulators, and being able to isolate and control/measure the pressure/vacuum at different pipelines. 1

14 The Handbook of Geo-pressure-vacuum panel In the following, a brief description of the GeoLab triaxial pressurewater-vacuum panel is given. Technical reference and specification manuals of the various on-off valves, pressure-vacuum regulators and gauges are presented. 2

15 Chapter 2 The GeoLab Air pressure-water-vacuum panel In Photo 2.1 the pressure-water-vacuum panel, found in Laboratory of Geomaterials, is shown. As aforementioned, the GeoLab triaxial panel consists of three main pipelines: the air-pressure pipeline, the water pipeline and the vacuum pipeline. The initial design of pipelines actually comes from the air-pressure triaxial panel, designed by Wykeham Farrance. In order to cover the extended needs of the two triaxial apparatus (WF and VJTech) and one biaxial apparatus, the initial WF triaxial panel was extended. The GeoLab triaxial panel consists of the following four main pipelines: 1. Air pressure distribution line (WF Mod.No.13030/SN: ) 2. De-aired water distribution pipeline (WF Mod.No.13030/SN: ) 3. Vacuum distribution line (WF Mod.No.11680/SN: ) 4. CO 2 distribution line In the following sections, brief descriptions of the aforementioned parts will be given. 3

46 The Handbook of Geo-pressure-vacuum panel Figure 2.3: Imperial stepper motors controlling cell (right) and pore (left) pressure (external view). 2.1 Air pressure distribution line (WF Mod.No.:13030/SN: ) This is the major pipeline which distributes the air-pressure from the source (air compressor) to pressure regulators, gauges, lines, etc. In the main pipeline, an analog pressure gauge is mounted on the panel, measuring the air pressure coming from the source (air compressor). This main air pressure line bifurcates in five pressure lines: The stepper motors pressure line, the cell and pore pressure line, the silicon oil tank pressure line and the main pressure line for the triaxial permeability panel (see The handbook of Geotest GeoBiaxial manual ) Imperial stepper motor pressure line This branch supplies with air-pressure coming from the source, the two Imperial stepper motors (see Photo 2.3), controlling the cell and pore pressure. Each stepper motor has one input and one output line. The input line is connected to the stepper motor pressure line, while the output line of each stepper motor is connected to an air distributing block (see Photo 2.5). The cell and pore pressure air distributors supply with regulated air pressure the air-water cells, connected in the cell and pore pressure lines of the triaxial apparatus, respectively. The air-water cells are equipped with a bladder, that is an elastic membrane, which separates the de-aired water from the pressurised air. 5

53 The Handbook of Geo-pressure-vacuum panel Figure 2.6: WF12250 air pressure regulators for cell (right) and pore (left) pressure line WF12250 air pressure regulators for cell and pore pressure line This branch almost serves as the previous one, but for mechanical air pressure regulation. Two Wykeham Farrance pressure regulators (WF12250), which are connected to the main air pressure pipeline in parallel, regulate the air pressure. The first one (seen from the right) controls the cell pressure, while the second one, the pore pressure. Both outputs of the pressure regulators are connected to the air-water cells, thus allowing for manual control and regulation of the air pressure WF12250 air pressure regulator for silicon oil tank pressure line The third and last (as seen from the right) air pressure regulator is a WF12250 air pressure controller, whose output is connected to the silicon oil tank. This is the reservoir of the silicon oil used for the biaxial apparatus. The biaxial cell is filled with silicon oil, stored in the tank. Due to its viscosity, air pressure is used to press the oil in its tank and fill the cell. 7

55 The Handbook of Geo-pressure-vacuum panel Figure 2.9: De-aired water distribution pipeline (WF Mod.No.13030/SN: ) Triaxial permeability panel pressure line The last connection to the main air pressure pipeline is the one supplying air pressure to the triaxial permeability panel. The triaxial permeability panel (for more details see Chapter 5 of The Handbook of the Geotest Geobiaxial apparatus ). 2.2 De-aired water distribution pipeline (WF Mod.No.13030/SN: ) This is the main water pipeline, which supplies with de-aired water the cell and pore pressure lines of the two triaxial and one biaxial apparatus. The de-aired water pipeline is found in the lower part of the GeoLab triaxial panel, and bifurcates in seven main branches. The first one (seen from the right) is connected to the main water source. Just beneath there is a second supply, for de-stilled water. Moreover, three water pipelines are connected to the main pipeline, which serve as distributors to the cell and water pressure air-water cells and to the triaxial permeability panel (biaxial apparatus). The last two branches are connected to the de-airator and to the de-airing tank, mounted just upon the GeoLab triaxial panel The NOLD de-aerator This is the device used to de-air water. De-aired water is used when performing drained or undrained tests in triaxial and biaxial experiments. The use of de-aired water mainly stems from the fact that the WF type au- 9

Figure 2.11: The NOLD de-aerator in Laboratory of Geomaterials. tomatic volume change apparatus used in the Laboratory of Geomaterials measures the volume of water expelled or sucked by the specimen during the consolidation of drained phase. Any trapped air in the system of pipes or apparatus will inevitably lead to limited accuracy, concerning the volume change of the specimen, due to the fact that air is much more compressible to de-aired water. For this reason, a NOLD de-aerator has been installed in the water pipeline of the Geolab triaxial panel. This device is described in detail in the following pages, where its technical reference is given. 10

It is made of perspex mounted upon the panel. The tank has three inlets/outlets which are namely: The water inlet, situated at the top comprising en elbow joint connected to a spray nozzle. The vacuum inlet, which provides for connection with either a vacuum jet or vacuum pump. The de-aired water outlet, which operates an outflow under gravity. The tank is deliberately mounted upon the panel, so as to use the gravity for filling the two triaxial cells, the two air-water cells (cell and pore pressure) and allow for saturation of the specimen. In the following, technical specifications of the WF11670/11680 de-airing tank are given in detail. 11

131 Model 2100 Nold DeAerator Applications The Model 2100 Nold DeAerator is used in The preparation of deaired, bubble-free, water or glycol solutions (antifreeze), for use in hydraulic settlement systems, twin-tube hydraulic piezometers, and manometer-type water-level monitoring systems The preparation of deaired water for use in soil testing laboratories, triaxial tests, saturation and permeability tests The degassing of hydraulic oils Numerous other nongeotechnical applications such as biological research, food and chemical production, ultrasound imaging, etc. Model 2100 Nold DeAerator shown degassing a liquid (6 liter capacity pictured). Operating Principle The Nold DeAerator is designed to quickly remove dissolved gasses from liquids without the application of heat. It was originally developed for geotechnical applications to allow the preparation of de-aired water for use in hydraulic twin-tube piezometers and hydraulic settlement systems, where the presence of air bubbles in the connecting tubing would give rise to measurement errors. The degassing is accomplished by means of cavitation and nucleation. Cavitation, an ultra-high vacuum, is produced behind the blades of a rotating impeller. The violent agitation so produced breaks up the liquid into a fine mist-like spray of particles (nucleation), from which the dissolved gasses can easily escape. Centrifugal forces hurl the released gasses (air, H 2 S, SO 2, methane, radon, etc.) outwards where they bubble up to an evacuated space above the liquid surface. From there, the gasses are drawn off through a vacuum tube. Geotechnical Instrumentation

132 Model 2100 (8 liter capacity pictured). Typical system components include (from left to right) a storage tank, the Model 2100, a moisture trap, liquid supply and vacuum pump. Advantages and Limitations The Nold DeAerator can quickly (within 3 to 5 minutes) produce de-aired water with a purity of less than 1 ppm dissolved air without the need for application of heat. The Nold DeAerator can be used with all water and glycol mixtures and with hydraulic oils. Liquids which will attack acrylic plastics (such as those containing alcohol), should be avoided. Vacuums must exceed 29.5 inches Hg (12 Torr) for the DeAerator to be effective. Belt-driven, two-stage, oilfilled vacuum pumps of 25 liter per minute capacity are preferred. Where the water aspirator is used, the water pressure must exceed 65 psi (450 kpa) and approximately 12 liters of water will be needed. The water aspirator provided has a 3/8 NPT male connector, which must be adapted to. System Components The Nold DeAerator consists of a sealed acrylic chamber which can be evacuated using either a vacuum pump (not supplied) or a water aspirator supplied with the equipment. The vacuum is used to draw liquid into the chamber through an intake valve. At the base of the chamber is a multi-bladed impeller, which is connected via a magnetic clutch to an electric motor. Energizing the motor rotates the impeller producing cavitation and nucleation. Wetted parts are made from acrylic, polypropylene, epoxy plastics, Buna-N O-rings, stainless steel, brass, and tubing of PVC and latex rubber. Accessories Storage tanks are available for the storage of de-aired liquids. These tanks are identical to the expansion tanks used in heating systems. They contain a rolling rubber membrane that separates one end of the tank from the other, allowing the tank to be filled and emptied without the de-aired liquid coming into contact with the air. Technical Specifications Standard Capacities 6, 8 liters Degassing Purity 0.6 ppm Vacuum Requirements 750 mm Hg, (12 Torr), or better Power Supply 120 V 60 Hz or 240 V 50 Hz Power Consumption 14 watts L W H (6 liter) mm (8 liter) mm Shipping Weight 9 kg The World Leader in Vibrating Wire Technology TM Geokon, Incorporated 48 Spencer Street Lebanon, NH USA Geokon maintains an ongoing policy of design review and reserves the right to amend products and specifications without notice geokon@geokon.com Geokon, Incorporated.

139 The Handbook of Geo-pressure-vacuum panel Figure 2.15: The Imperial constant strain rate pump The Imperial constant strain rate pump This is a portable constant strain rate pump. It has a maximum capacity of 2MPa pressure and is mounted on the air pressure/water/vacuum panel. The pump has to openings: One for filling the chamber of the pump with de-aired water (inlet) and the other to push the de-aired water out of the chamber (outlet). The pump is supplied with de-aired water from the third branch of the main de-aired water pipeline, while its outlet is connected to a distribution block, mounted on the panel. In this way, the one outlet of the pump is split into three, thus supplying with high pressure both triaxial and biaxial apparatus. 2.3 Vacuum distribution line (WF Mod.No.11680/ SN: ) The vacuum line consists of two main parts: The first part is directly connected to the rotary vacuum pump, while the second one, is connected to a Nullmatic pressure/vacuum regulator. An analog vacuum gauge is mounted to the first part of the vacuum pipeline, measuring the vacuum supply from the pump. Both parts of the vacuum pipeline are separated by an on-off valve. Three outlets of the part of the vacuum pipeline that is connected to the pump, are used to supply vacuum to the NOLD de-airator, to the WF11670/WF11680 perspex de-airing tank (vacuum inlet) and to the triaxial and biaxial mold, when forming a sand specimen. The Nullmatic pressure/vacuum regulator allows for regulation of the vacuum, by mixing compressed air with vacuum. The regulator has two inlets, one for vacuum and another for pressure. By adjusting the pressure with its knob key, 13

Three branches supply with regulated vacuum the triaxial permeability panel and the pore pressure lines in the two triaxial and one biaxial apparatus. 14

153 Regulators Models 40, 41, and 42 Precision Pressure Regulators Introduction Features & Benefits Multi-stage, low-droop precision regulators maintain constant output over wide changes in flow and supply pressure Epoxy powder coat paint delivers improved corrosion resistance Wide selection of regulated pressures [1" to 450 psi] affords application versatility Patented Nullmatic pressure regulation system provides reliable maintenance-free operation Description The Models 40, 41, and 42 Precision Pressure Regulators control air pressures in applications where precise and dependable regulation is required, such as pneumatic instrument circuits, test stands, production checking fixtures, and industrial air gages. As such, they are suitable for deadend service, and flows up to a maximum of 110 scfm. A unique, two-stage piloted design provides outstanding accuracy. Rugged construction with no links, levers, pivots, or other friction-producing members ensures reliable, maintenance-free operation. These features allow a regulator to maintain constant output pressure, regardless of even the widest changes in flow or supply pressures. In fact, a regulator using a Model 40, 41, or 42 is practically a self-contained pressure controller operating its supplyplunger valve via a built-in, high-gain pneumatic amplifier. A fine-turn, precision screw is used to manually load the range spring, which sets the regulated pressure. When the adjusting knob is turned clockwise, the increased spring force is exerted on the top diaphragm assembly, decreasing the nozzle clearance and increasing the pilot pressure. Because the source for pilot pressure is supply air flowing to the pilot pressure chamber through the restriction screw, the increased pilot pressure forces the exhaust diaphragm assembly downward. This action closes the exhaust port, and contacts and moves the valve plunger, which opens the supply port. This increases the regulated output, which also feeds back to the top diaphragm assembly. The regulator locks-up or throttles at the new output value when the feedback force of the top diaphragm assembly equals the range spring force. A safety release valve is incorporated in the top diaphragm assembly of several models. It operates if the regulated pressure increases 3 tnú psig more than the set pressure and exhausts air through the atmospheric vent in the top housing. Overpressure causes the diaphragm to move upward, which opens the safety release valve.

155 Regulators Models 40, 41, and 42 Precision Pressure Regulators Technical data Graph 1 Droop Effect Test Procedure: Each 30-psig-range regulator was adjusted to 25 psig with 100 psig supply and no flow. Flow was increased to maximum capacity. All regulated pressure readings were taken at gauge connection in the body of the regulator. Note: For performance curves on Model 40-2 and 40-7, request drawing # and , respectively

156 Regulators Models 40, 41, and 42 Precision Pressure Regulators Technical data Graph 2 Maximum Air Flow, SCFM Delivered * Supply pressure for other models will be determined by multiplying the pressure(s) above by the flow values shown below: Model Value Model 40H 4.5 Model 42 4 Model 42H 14 Graph 3 Air Consumption Graph 4 Drift Effect 7 Test Procedure: Regulators were set at 20 psig output with 100 psig air supply. Supply was turned off for one week, after which supply was turned on at time 0. The Nullmatic regulator bleeds only the amount of air that passes through the pilot nozzle when there is no demand for output flow. The exhaust port starts to close as soon as the flow of regulated air is increased to the output, and it closes completely before the pilotplunger valve opens. Full pilot flow is then delivered to the output. 7.4

Figure 2.18: Detendeur HBS reducing high CO 2 pressure from bottle. 2.4 CO 2 distribution line CO 2 under pressure is usually used in the saturation phase in drained and undrained tests. CO 2 is much more dissolvable that air in water, thus allows for larger saturation degrees. CO 2 is stored under high pressure (300bar) in a tank or bottle. A pressure regulator (detendeur HBS) (see Photo 2.18) is installed on the bottle to reduce the output pressure in the range (0-10bar). The outlet of the pressure regulator is connected to a distribution block on the air pressure-water-vacuum panel. The distribution block has, apart from the inlet CO 2 on-off valve, three CO 2 regulated outlets. A Camozzi type Series C regulator (0-4bars) is installed in the distribution block regulating the input CO 2 pressure. 15

163 Chapter 3 The GeoLab air compressor One could name it the main engine of a typical Soil Mechanics Laboratory. Indeed, the air compressor is the unit that supplies with compressed air vital apparatus and parts of a triaxial air pressure/water/vacuum panel. The selection of an air compressor is mainly controlled by two parameters: Its maximum working pressure and its air flow discharge/capacity. The air compressor is housed near the Lab, in a special place, away from the apparatus, for safety reasons. Its maximum air pressure capacity is 12bars with a tank volume reaching 100lt. The minimum and maximum working pressure can be regulated by a knob key. A copper pressure line from the stockhouse to the laboratory is used to connect the main air pressure pipeline of the panel with the air compressor. More information and technical data concerning the air compressor can be found in the following pages. 17

165 Chapter 4 The GeoLab vacuum pump As the air compressor serves as the main source of pressurized air for all apparatus, a rotary vacuum pump supplies the main vacuum pipeline with vacuum. The pump may reach a vacuum level as low as -0.9atm, and its capacity is characterised by the air-discharge. Like the air compressor, the vacuum pump is installed in a stockhouse and is connected to the main vacuum pipeline in the panel by a copper pipe. More information and technical data concerning the vacuum pump can be found in the following pages. 19
