1 INTRODUCTION The HM-4165 Pressure Control/Distribution Panel is designed to control cell and back pressure outputs for up to three triaxial cells. A digital pressure display allows the monitoring of the pressure of each output individually. The HM-4165 panel includes the air and water distribution capabilities including tap water, as well as de-aerated water. The panel also controls the vacuum necessary to remove air from the tap water in the de-airing tank.
2 are for de-aerated water return from the de-airing tank, tap water going to the de-airing tank, and air/vacuum to the de-airing tank respectively. On the face of the panel are the connections for air pressure outputs to the HM-4151A Bladder Air/Water Cylinders for cell pressure and back pressure, tap water and de-aerated water for the bladder cylinders, automatic volume change, and the triaxial cell.
3 which connects to the volume change device. This adapter is supplied with the panel. TRIAXIAL CELL CONNECTION The triaxial cell has compression fittings on the front as shown in Figure 4. The cell connection on the triaxial cell connects to the water connection at the Cell connection on the front of the panel. The base connection on the triaxial cell connects to the volume change device as shown in Figure 2 and not directly to the panel.
4 AIR/WATER CONTROL VALVES There are several control valves on the panel for on/off operation of the air and water control. There are two valves under the De-Airing Tank heading (Figure 6). These valves control flow of water to and from the de-airing tank and air or vacuum to the tank. The water flow valve either allows tap water to fill the tank or allows the tank to be drained for cleaning and maintenance.
5 AIR FILTER There is an in-line air filter which filters the incoming air from the compressed air source. It also traps water and other fluids in the line. MAINTENANCE There is very little maintenance required. The digital gauge operates with AC power. If the gauge fails to operate, first check the transformer to determine if it is operational. The air filter should be checked every day to determine if the white filter element is dirty or if fluid must be drained from the clear plastic bowl.
