Why are rubber joints installed on water pumps?

Rubber Joint Supplier shares that rubber joints are hollow rubber products used for flexible connection between metal pipes. It is composed of inner and outer layer rubber, curtain layer and steel ring, which is formed by vulcanization and then combined with metal flange or parallel joint loose sleeve. It not only reduces vibration and noise, but also compensates for thermal expansion and contraction caused by temperature change, which is widely used in various pipeline systems. In the modern era of rapid development, rubber joints have been used in various pipelines. And pump installation why need to install rubber joints. What's the use of rubber joints?

Rubber joints are also known as shock absorbers, soft joints such as flexible rubber joint For power, rubber soft connections, pipe shock absorbers and so on. It is commonly used in civil construction water supply and drainage engineering, fire control pipe network, pump room unit pipeline undertaking, sewage treatment pipeline connection, high pressure gas liquefaction medium transportation, oil, ships and so on. It is one of the most commonly used rubber fittings in the world. With reduce pipe noise, good sealing, light weight, easy installation and maintenance, long service life.

The rubber connector installed at the pump outlet can be shock absorption, two is to heat expansion and cold contraction needs, three is convenient to disassemble the valve and maintenance needs; The actual installation sequence should be: rubber soft joint, check valve, gate valve. The pressure gauge should be installed at the pump outlet, but must be in front of the check valve. In normal operation, the gate valve is not easy to operate, while the check valve is frequently operated, so the maintenance probability is relatively high. Closing the gate valve of the pump outlet pipe during maintenance can repair without affecting the normal operation of the system. The pressure gauge is installed in front of the check valve to prevent the impact and damage of water hammer on the pressure gauge.
