Description
Technical field
The utility model relates to a kind of centrifugal pump fields, more particularly, to the cooling component and centrifugal pump of a kind of transmission shaft.
Background technique
With the fast development of modern industry, more and more operating conditions can make transmission shaft work in high temperature, high pressure, high speed
In environment.The transmission shaft of centrifugal pump generates a large amount of frictional heat when rotating at high speed, and the temperature rise of transmission shaft is made to be much higher than it
Allow operating temperature rise range, causes lubricating oil coking due to high temperature, centrifugal pump is caused to can not work normally.In order to reduce centrifugal pump
Transmission shaft temperature, routine techniques cools down to transmission shaft using water-cooling pattern.In the outer sheath of the transmission shaft of centrifugal pump
Enter cooling component, the inside of cooling component forms cooling chamber, transmission shaft rotates in cooling chamber, cooling water from cooling component into
Enter in cooling chamber at the mouth of a river, heats up after being influenced in cooling water by high temperature transmission shaft, the water after heating is again out of cooling chamber
The external world is discharged at discharge outlet.It is sealed between cooling component both ends and bearing using seal assembly, to prevent cooling water from cooling
It is leaked in component.Wherein elastic seal cap mode is usually used to seal close to one end of centrifugal pump bearing, the week of elastic seal cap
The outer wall of side fitting cooling component is simultaneously screwed, and transmission shaft is passed through from the through hole at elastic seal cap center.Its disadvantage exists
In: the temperature near transmission shaft and transmission shaft is still higher, and elastic seal cap works under high-temperature for a long time, is using one
After the section time, often deformation occurs for set elastic seal cap in the cooling component of centrifugal pump bearing one end, causes
The outer surface that can not fit closely cooling component of elastic seal cap, or even tilted from fixed position, sealing performance is deteriorated, and causes
Cooling water enters the lubrication near bearing more particularly along the transmission shaft of centrifugal pump along in other positions for leaking into centrifugal pump
In fuel tank, centrifugal pump is damaged, service life is short.
For customer service disadvantages mentioned above, the utility model patent that China Patent No. is 201621242320.9 discloses a kind of biography
The cooling component and centrifugal pump of moving axis, cooling component include being provided with the cooling main body of cooling chamber, and being provided in cooling main body can
For the channel that transmission shaft passes through, channel is connected with cooling chamber, and the side in channel is provided with seal assembly, the side of cooling main body
Be provided with seal chamber on wall, fixed in the seal assembly insertion seal chamber and by ring set component, seal assembly include for
Transmission shaft across sealing frame body, the outside seal that is arranged in sealing frame body and cooling main body and setting in sealing frame body
Inner seal liner between transmission shaft, outside seal and inner seal liner are surrounded by sealing frame body, cooling main body and transmission shaft, excellent
Point has been the fixed form of conventional screw, and fixation is stronger；Outside seal and inner seal liner by sealing frame body, cooling
Main body and transmission shaft surround, and drastically reduce the deformation space of outside seal and inner seal liner compared with prior art, reinforce
Sealing effect.
The prior art prior art is added using seal assembly is arranged in seal chamber by changing the structure of seal assembly
Strong sealing function, its shortcoming is that: although 1, leakproofness is reinforced, still suffer from a small amount of cooling water leakage；2, the sealing
Structure is complex, as long as soon as component malfunction, is unable to reach the demand of sealing, fault-tolerance is lower.
