Sealing performance of drainage pump
The sealing performance of the drainage pump is a key factor to ensure its stable operation and prevent medium leakage. The following is a detailed introduction to the sealing performance of the drainage pump:
1. Sealing form:
Drainage pumps usually adopt a variety of sealing forms, including packing seals, mechanical seals, magnetic seals, etc. Among them, mechanical seals are widely used due to their excellent sealing performance and long service life.
2. Mechanical sealing characteristics:
Mechanical seals form a seal through close contact between the static ring and the dynamic ring, and use components such as springs to generate pressure to ensure the sealing effect.
Compared with packing seals, mechanical seals have a longer service life and better wear resistance.
The mechanical seal consists of a sealing structure, an abnormal structure, a pressure-bearing structure, a supporting structure, and a manual structure, and its core is the sealing surface and power transmission.
3. Sealing material:
The selection of sealing materials is crucial to the sealing performance of the drainage pump. Different working environments and media require the use of different sealing materials to ensure the reliability and durability of the seal.
4. Sealing performance evaluation:
The sealing performance of the drainage pump can be evaluated in a variety of ways, such as measuring the length change of the compensation spring, the size of the dynamic and static ring sealing surface, and the gap between the dynamic and static rings and the shaft or sleeve.
In addition, the reliability of the seal can be ensured by checking the mechanical seal tightness.
5. Maintenance and care:
The sealing performance of the drainage pump requires regular maintenance and care to ensure its long-term stable operation. This includes checking the wear of the seal, replacing damaged seals, cleaning the sealing surface, etc.
