Mechanical seal manufacturer Describe the function of the seal

1、 Improve machine efficiency and reduce energy consumption.

1. Reduce the internal leakage, external leakage and penetration of the machine, and improve the volumetric efficiency of the machine. For example, Daqing Refinery will coking 5FDJ5 × 2. The impeller mouth ring of centrifugal pump was changed into mechanical seal, which improved the pump efficiency by 3.6% and 5.6%.

2. Reduce friction loss and improve mechanical efficiency of the machine. For example, changing the double end seal to single end seal, changing the unbalanced type to balanced type, and reducing the seal at the closed end of the double support bottom reducing pump (the so-called chopping pump) can reduce the friction loss and improve the mechanical efficiency.

3. Change the sealing method to improve the efficiency of the machine or unit. For example, the canned motor pump is replaced by a mechanical seal pump to improve the efficiency of the motor; Adopt magnetic drive pump to improve machine efficiency.

4. Change the auxiliary system to reduce energy consumption and improve unit efficiency. For example, hot oil pump self flushing is changed to small impeller circulating flushing; Double face seal is replaced by single face seal to save energy consumption of auxiliary oil sealing system.

2、 Save raw materials. For example, the recovery of process fluid can reduce or eliminate the loss of power steam and process fluid, and reduce the loss of sealing oil.

3、 Improve machine reliability. For example, the leakage and life of the shaft seal determine the reliability of the shaft seal and the machine.

4、 Safety and environmental protection. According to the investigation report of a factory in Japan, 32 of the 786 accidents were caused by leakage (42%). In addition, process fluid leakage will also cause environmental pollution, including air pollution, water pollution and workshop environmental pollution.
