Description

Shaft seal cooling mechanism with double-outlet circulation pipeline

Technical Field

The utility model relates to a shaft seal assembly, in particular to a shaft seal cooling mechanism with double discharge circulation pipelines.

Background

The shaft seal is a friction seal or stuffing box to prevent fluid leakage between the compressor or other fluid transport device shaft and the bearing. The shaft seal is a sealing device arranged for preventing leakage between the pump shaft and the housing. Common types of shaft seals are packing seals, mechanical seals and dynamic seals. The shaft seal of a reciprocating pump is typically a packing seal. When the delivery of a medium that does not allow leakage is not allowed, a diaphragm type reciprocating pump may be employed. The shaft seal of rotary pump (including vane pump, rotor pump, etc.) mainly has packing seal, mechanical seal and dynamic seal.

The centrifugal pump is used for conveying fluid by driving the fluid to rotate through centrifugal force generated by an impeller of the rotary pump and mainly comprises a motor, the impeller, a pump body and a shaft seal device. When the centrifugal liquid pump is used, liquid in the pump is conveyed to the outlet under the centrifugal action of the impeller connected with the motor, then the cavity of the pump is vacuumized, and the inlet liquid is sucked into the pump to form circulation. During the use process, the temperature of the machine seal can be rapidly increased due to the friction of the machine seal, so that the machine seal needs to be matched with a cooling device for use.

The traditional cooling device is characterized in that a water path is connected to a sealing cavity of the shaft seal for circulation to realize cooling, and the technical scheme that cooling liquid is circulated by single water path circulation has poor cooling effect on the pump and the bearing.
