The high sealing and leakage-free characteristics of chemical pumps are achieved through the use of advanced sealing technology, advanced materials, double sealing systems, etc. These measures not only improve the safety and reliability of chemical pumps, but also reduce maintenance costs and environmental pollution risks, providing a strong guarantee for the smooth progress of chemical production.

The horizontally split multistage centrifugal pump adopts a volute-shaped pump body. Each impeller has a corresponding volute chamber on the periphery, which is equivalent to installing several single-stage volute pumps on the same shaft to work in series, so it is also called a volute multistage pump.

The difference in balancing devices between multi-stage pumps and single-stage pumps is mainly reflected in the generation and balancing methods of axial force.

The symmetrical arrangement of multi-stage centrifugal pump impellers is an effective axial force balance method, which has the advantages of good axial force balance, reduced vibration and noise, and improved pump efficiency. However, in practical applications, attention needs to be paid to issues such as impeller machining accuracy, seal ring wear, and pump casing structural complexity.

When lifting the submersible pump out of the water, attention should be paid to the details of rope operation, avoiding impact and falling, checking cables and connectors, cleaning and maintenance, storage and preservation, etc. By following these precautions, the safe use and long-term stable operation of the submersible pump can be ensured.

The normal use of submersible pumps requires attention to details and maintenance work in many aspects to ensure its safe and efficient operation and extend its service life.

Preventing vacuum pump overload requires multiple aspects, including reasonable selection of pump type and specifications, control of vacuum speed and load, installation of protective devices, strengthening cooling and heat dissipation, and regular inspection and maintenance.

There are many ways to improve the water suction reliability of the water pump, and the appropriate method should be selected according to the actual situation and needs of the project. At the same time, strengthening daily maintenance and inspection is also an important measure to ensure the long-term stable operation of the water pump.

The order of the outlet valve of the water pump is usually soft joint, check valve, gate valve (or butterfly valve), and the pressure gauge is installed on the water outlet of the water pump and located in front of the check valve. This order design takes into account both the normal operation requirements of the system and the convenience of maintenance.

There are five main leakage points of mechanical seals for pumps. These leakage points vary according to the structure and working environment of the mechanical seal
