Installation of rubber pipe joints in sewage treatment plants

When installing rubber pipe joints, keep the inside and outside surfaces of the joints clean and avoid scraping the surface of the rubber parts with hard objects. Prevent the rubber joint from being damaged by mechanical force. Pay attention to the rubber pipe joint installation to prohibit slipping operation on the motor bearing to avoid damage to the connection. If the rubber pipe joint is installed on the pump unit, it is caused by axial displacement due to excessive pressure on the pipe. It is necessary to avoid damage caused by any external force. If the rubber joint is damaged, the whole pump will produce pressure that cannot be operated.
Note that axial displacement, axial displacement or lateral displacement must not be affected by the rubber sealing ring, thus affecting the sealing of the rubber and reducing the operating life of the pipe. Water pump unit rubber pipe joint, also known as rubber expansion joint, rubber soft joint, rubber hose. It is made of soft rubber and elastic synthetic rubber as the main raw material, and is made by mixing, extrusion or vulcanization processes. Compared with other similar products, it has excellent impact resistance, low temperature resistance, acid and alkali resistance, chemical resistance and other characteristics. It is mainly used for pipeline and equipment. Has good joint structure shape. Resistant to high temperature, strong acid, alkali, high temperature and other chemicals. Suitable for large diameter pumps with pressure up to 1.5 MPa. The products are widely used in chemical, metallurgical, petroleum, electric power, pharmaceutical, food and other industries. It can prevent the pipeline from damage and leakage phenomenon, and protect the pump set as well as the equipment to make it work better.
In order to make a good combination of various properties and avoid any expansion or contraction of the rubber joint due to temperature changes, it must be connected with axial fixation. Problems to be noted in the installation of rubber hose joint: According to the actual needs, two flanges can be connected to each other separately, or two flanges can be used to connect, and the gap between the two flanges should not be more than 1 mm. to prevent thermal expansion, a layer of heat insulation gasket should usually be added between the two flanges. Fix the two bolts with bolts and level with the flange. The rubber hose joint part should not be bent or compressed, otherwise it will damage the pipe, so the rubber hose joint should not be installed on the pipe. For pumps and valves make sure that the rubber hose joint is sealed and installed on the pipe because it plays a good role. It also protects the equipment in the pipeline to reduce energy consumption. The protection of water supply equipment is remarkable. It provides long-term stable, high-quality conveying effect. Rubber pipe joint for the ball and flange contact surface coated with anti-rust oil to prevent contamination by oil; installation is strictly prohibited in the motor bearing for slipping operation and rotation axis to move to the appropriate position. Prevent displacement to affect the life of the pump unit rubber pipe joint.
