What are the requirements for the installation of water pump soft connections?

1. Rubber soft connections can be used before and after the gate valve. Its functions are firstly shock absorption, secondly, the need for thermal expansion and contraction, and thirdly. It is convenient for valve disassembly and maintenance needs; the check valve only needs to be on the water pipe after the water pump, and its function is to protect the water pump. Generally installed after the gate valve.

2. I can’t think of any significance in placing the check valve in front of the water pump.

3. The actual installation sequence should be: rubber soft connection, check valve, gate valve. The pressure gauge is best installed on the water pump outlet, but it must be in front of the check valve.

4. The rubber soft connection is for vibration reduction. Of course it is the connection between the water pump and the piping system.

5. During normal operation, the gate valve does not operate very often, but the check valve operates frequently, so the probability of repair is high. During maintenance, closing the gate valve of the pump outlet pipe can repair it without affecting the system. of normal operation.

6. The pressure gauge is installed in front of the check valve to prevent the impact and damage of the pressure gauge from water hammer.

7. Some people have proposed that for large-diameter pipes, the check valve should be installed behind the gate valve to facilitate opening and closing. This is unrealistic. Because the check valve exists when the water pump stops, the water pressure before and after the gate valve installed after the check valve is consistent, and there is no problem with the opening and closing of the gate valve. Of course, large-diameter valves themselves are more difficult to operate.
