Precautions for selecting corrosion-resistant pumps

Precautions for selecting corrosion-resistant pumps

The anti-corrosion pump should reasonably determine basic parameters such as pump flow and head based on the process summary. Usually, normal wear and speed changes of the pump are considered, which may lead to a decrease in lift. Therefore, when selecting a pump, the lift of the pump can have a margin of 2% to 5%.

How does a threaded check valve work

How does a threaded check valve work

Thread check valve refers to a valve that automatically opens and closes the valve disc by relying on the flow of the medium itself to prevent medium backflow. It is also known as a check valve, one-way valve, backflow valve, and backpressure valve. The threaded check valve is an automatic valve that mainly functions to prevent medium backflow, prevent pump and drive motor reverse rotation, and discharge the container medium. The threaded check valve can also be used to supply pipelines to auxiliary systems where the pressure may rise above the system pressure. Thread check valves can be mainly divided into swing type thread check valves (rotating according to the center of gravity) and lift type thread check valves (moving along the axis).

Three Correct Selection Methods for Quick Couplers

Three Correct Selection Methods for Quick Couplers

About the Correct Selection of Quick Couplers 1. Determine the joint based on the type and temperature of the fluid. The type and temperature of the fluid have a significant impact on the quality of the joint, so the selection should be tailored to local conditions. If the fluid is air, a quick coupling made of steel can be used. If the fluid is liquid, a quick coupling made of brass or stainless steel can be used. 2. Select appropriate joints based on the pressure of the fluid. The pressure of the fluid is also the key to selecting a stainless steel quick connector, and the pressure resistance of different structures of the connector varies. Correct usage of quick connectors 1. Conditions. The humidity of the working environment
