Abstract
An oil chamber seal mechanism comprises a mechanical seal, a framework oil seal, an oil filling chamber, a motor rack, a pump cover, a shaft, etc. Oil in the oil filling chamber flows into the friction pair end surface of the rotating seal ring and the stationary seal ring of the mechanical seal and forms an oil film. The oil film performs a lubricating function for the mechanical seal.
Description
Technical field
The utility model is applicable to water pump.
Background technique
At present, water pump is continued to use traditional design mode always, and mechanical sealing linkage ring and stationary ring friction pair end face frictional force are big, causes unit efficiency not high, and mechanical seal is low working life.
Summary of the invention
Not high in order to overcome present pump overall efficiency, mechanical seal low problem in working life is designed grease chamber's sealing mechanism, and the oil in the grease chamber is by the friction pair end face between inflow rotating ring of the gap between stationary ring and the pump shaft and the stationary ring, form oil film, thereby play lubrication mechanical seal.Thereby improve the working life of mechanical seal, reach the not only energy-efficient but also long-lived purpose of water pump.
The technological scheme that its technical problem that solves the utility model adopts is as follows:
Constitute the grease chamber that adds of a sealing by motor frame, pump cover and outside framework oil seal, add oil in the grease chamber and go into the friction pair end face of mechanical sealing linkage ring and stationary ring along axial flow, form oil film, thereby lubricated effect is played in mechanical seal, thereby improve the working life of mechanical seal, reach the not only energy-efficient but also long-lived purpose of water pump.
Description of drawings
Accompanying drawing is a grease chamber of the present utility model sealing mechanism schematic representation.
Embodiment
Referring to accompanying drawing, a kind of grease chamber of the present utility model sealing mechanism by motor frame 1, outside framework oil seal 2, pump cover 3, add grease chamber 4, mechanical seal 5, axle 6 etc. and form.What motor frame 1, pump cover 3 and outside framework oil seal 2 constituted a sealing adds grease chamber 4, the oil that adds 4 li of grease chambeies flows into the friction pair end face of mechanical seal 5 rotating rings and stationary ring along the direction of axle 6, form oil film, thereby play lubricated to mechanical seal 5, also just improve the working life of mechanical seal, reached the not only energy-efficient but also long-lived purpose of water pump.
Claims (1)
1. grease chamber's sealing mechanism comprises mechanical seal, outside framework oil seal, adds the grease chamber, motor frame, pump cover, axle etc., it is characterized in that motor frame, pump cover and outside framework oil seal have constituted a kind of mechanism that adds the grease chamber of a sealing.
