China Gear Pump -Gear Pump Pay Attenti (For Sale)
China Gear Pump tips gear pump should pay attention to the following when designing the pipeline:
A. Reasonably choose the diameter of the gear pump pipe, the pipe diameter is large, the flow velocity is small, the resistance loss is small, but the price is high, the pipe diameter is small, the resistance loss will increase sharply, and the lift of the selected pump will increase. With increased power, both cost and operating costs increase. Therefore, it should be considered from a technical and economic perspective.
B. The discharge pipe and its pipe joints should take into account the maximum pressure that can be withstood.
C. Pipe arrangement should be arranged as straight pipe as much as possible, minimize the attachments in the pipe and minimize the length of the pipe. When turning, the bending radius of the elbow should be 3 to 5 times the diameter of the pipe, and the angle should be as large as 90. C.
D. The discharge side of the pump must be equipped with a valve (ball valve or shut-off valve, etc.) and a check valve. The valve is used to adjust the operating point of the pump. The check valve prevents the pump from reversing when the liquid is reversed and prevents the pump from hitting the water hammer. (When the liquid flows backwards, it will generate a huge reverse pressure, which will damage the pump)
