| This device
is used to maintain cell pressure constant for a long duration and the system
can be used in place of conversions constant pressure system using mercury pots
where certain minimum heights are required. Problems like derivation of pump,
leakage of mercury etc. are eliminated in this system. This unit is smaller in
volume and cab be used in mobile laboratory also. Construction:
The system consists of an oil pump continuously driven by an electric motor during
the test period. The internal components are housed in a strong compact housing.
The piston on which weights are kept rotates with minimum friction. A transparent
oil water vessel is provided to transmit pressure to the cell. A hand pump provided
facilitates priming and to maintain constant pressure during power failure.
Specificaions :
Rang : 0-20 bar (0-20kg/cm2)
Accuracy + 0.5%
Electric supply 230 volts. Single phase, 50 Hz, A.C. supply.
Supplied complete with Pressure Gauge, flow valves, connecting Pressure hose and
set of weights to give maximum pressure of 20 bar ( 20kg/cm2).
