[Pump News Asia] pump is a high pressure pump operating procedures an important step, then when you open the pump, you need to follow what order? The following is the pump on the order of introduction of high pressure pump. (1) Check the pump, water tank (gas) and pipe valve, water suction valve, circulation valve, all in the open position, open the high-pressure pump pump discharge valve and lubrication Pump cooling water valve; (2) start the lubricating oil pump, running for 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; (4) After the high-pressure pump is operating normally, close the solenoid valve of the circulating valve and plug in the power plug. When the water level rises to above level 4, close the valve of the lowest liquid level solenoid 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. The above is the high pressure pump pump order, I hope everyone to operate the pump to follow this order to open the pump.
