High pressure reciprocating pump to open the pump order

High pressure reciprocating pump by the motor through the reducer, belt drive or stepless speed governor, driven crankshaft rotation, push rod through the slider (crosshead) so that the plunger for linear reciprocating motion in the pump head inlet Opening and closing the valve to achieve the purpose of suction and drainage. So in operation, the high-pressure reciprocating pump to open the pump to follow what order? With this question, then we introduce the high-pressure reciprocating pump to open the pump order. High pressure reciprocating pump pump sequence (1) to check the pump to start, water (gas) tank and pipeline valves, water suction valve, circulation valve, whether all in the open position, open the high-pressure pump head deflation valve and (2) start the lubricating oil pump, running 1 to 2 minutes, the oil pressure is 0.15 ~ 0.2 MPa, until the indicator light shows normal, start the high pressure pump main motor; (3) to be the first pump Close the exhaust valve immediately after the exhaust air is exhausted. (4) After the high-pressure pump is running normally, close the solenoid valve of the circulating valve and plug in the power plug. When the water level rises to level 4 or above, close the solenoid valve Iron switch, the water level rose to 7 (according to pump room design can also be issued in advance "can work" signal) to the hydraulic press issued a "can work" signal, the hydraulic press to work.
