Dead Weight Type Oil Water Constant Pressure System.
This device is used to maintain cell pressure constant for a long
duration and the system can be used in place of convensional constant
pressure system using mercury posts where certain minimum heights are
required.
Problems like deairiation of pump, leakage of mercury etc. are
eliminated in this system. This unit is smaller in volume and can be
used in mobile laboratory also. This can maintain pressure in the cell
upto 20 kg/cm.sq. Pressure is maintained constant in the system by a
balancing calibrated weights on a spindle against a column of oil,
operating under constant feedback.
Salient Features 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 on transmit
pressure to the cell. A hand pump provided facilitates priming and to
maintain constant pressure during power failure.Specifications : Range
