Working pressure: 2.0.~6.0MPa
Maximum working pressure: 7.0MPa
The oil cavity capacity: 4000cc
Working medium: 13# machine oil or 2# spindle oil
Use:
The hand pump and emergency shut-off valve supporting the use, suitable forliquefied petroleum gas storage and distribution station of large storage tank or tankeremergency shut-off valve in the working state, the use of the performance of thepump to control the emergency cut off valve to open or close to.
Description of the work principle and structure:
1, hand pump through the handle to do reciprocating movement, the increased pressure to open the emergency shut-off valve, medium can pass through, in case of fire or other emergency, the pressure valve is opened to discharge the hand oil pump,hydraulic system quickly to release the pressure, make emergency shut-off valveclosed immediately, or elevated temperature to 75 deg.c, installation emergency shut-off valve in the pump or melting of fusible plug immediately, to achieve automaticpressure relief wood, make emergency shut-off valve automatically closed quickly.
2, the main structure of hand pump is piston pressure oil absorption, oil inlet valveand oil outlet valve and pressure relief valve. By the plunger and import oil valveclosed, the sealing space formed is the work of oil pump chamber, when the piston to move up to the working cavity volume changes from small to large, as the cavity pressure below the atmospheric pressure of the oil inlet valve is opened, the oil filter oil valve into the working chamber. When the plunger moves down volume of working chamber from big to small, hydraulic cavity increases, the oil outlet valve is opened,the pressure oil into the oil system for emergency cut-off valve open. The pressure relief valve is used for oil system pressure relief and setting, work requires a pressure relief valve is closed, the need in the oil system pressure relief valve opens, namely the emergency shut-off valve closed.
3, the pump tank in the outer cavity pump, oil plug oil when opening the upper covercan be analyzed, such as the oil column volume is not enough when an external auxiliary fuel tank.
