Requirements for Rubber Flexible Hoses in Pump Installations

Requirements for Rubber Flexible Hoses in Pump Installation

Flexible joints can be installed both before and after the gate valve. Their functions include: 1) vibration reduction, 2) accommodating thermal expansion and contraction, and 3) facilitating the disassembly and maintenance of valves. The check valve is sufficient on the suction pipe after the water pump, serving to protect the pump. It is typically installed after the gate valve.

2. The installation sequence should be: rubber soft connection, check valve, and then the gate valve. The pressure gauge should be installed on the outlet of the water pump, but it must be placed before the check valve.

3. The flexible joint is for vibration reduction. Of course, it's at the connection point between the pump and the pipeline system.
