Abstract

The invention discloses an updraught multilayer isolated disc air compression seal-less diving pump, which comprises a motor unit, a sealing unit and an impeller unit communicated with the sealing unit, wherein an upper end cover of the motor unit is provided with a lower seal double-layer or multilayer stator isolated disc which is inserted into compaction sealing screw on a motor shaft together with an upper seal double-layer or multilayer rotor isolated disc on the motor shaft from an upper position and a lower position, and then the lower seal double-layer or multilayer stator isolated disc and the upper seal double-layer or multilayer rotor isolated disc are rotated to form a distance isolated space from top to bottom. The updraught multilayer isolated disc air compression seal-less diving pump realizes no need of movable and still sealing components and the improvement of the diving depth, reduces motor load and noise pollution and prolongs the service life, thereby realizing the prospect of no patient in a water pump in-patient department, saving a large amount of upkeep funds for global water pump carbon reduction, and also doing a good deed for the people of the whole world.

Description

Last suction multilayer spacer disks air compression seal-free submersible pump

Technical field;

The present invention relates to suck compression seal-free submersible pump; Especially relate to and inhale multilayer spacer disks air compression seal-free submersible pump.

Background technique;

The tradition submersible pump is many to be made up of motor, sealing and impeller, impeller is installed on the motor shaft, the intermediate portion of impeller and motor has been installed rubber seal or mechanical seal, because various foreign material, mixed water, silt and impaired, the very easily destruction damage sealing of turning round, in case water inlet causes burning motor.

Not having sealing water logging motor submersible pump is graphite sliding bearing, and for lubricated, we know that You Heshui is two notions by water; Often all being to move in quick-fried, as to mix water, the silt environment that rains, often all is that maintenance department has just become water pump inpatient department.Though air compression seal-free submersible pump, advantage is a lot of, and it is low to lack diving depth.

Summary of the invention;

Today, we adopted most advanced world invention, on inhale multilayer spacer disks air compression seal-free submersible pump, from then on pump motor promptly has oil, the no sealing technique of not intaking deeply again, and water pump finishes Packed history.For realizing above-mentioned technical purpose, the present invention takes following technical proposals;

Of the present invention going up inhaled multilayer spacer disks air compression seal-free submersible pump, and it is the impeller units that is connected with described sealing unit by electric motor units, sealing unit; It is characterized in that; Offer water intake being positioned on the housing of sealing unit; Offer water outlet on described impeller units top; The motor shaft of described electric motor units extends up in the impeller units, and the motor shaft that is positioned at impeller units is provided with impeller; The upper end cap that is positioned at electric motor units is provided with lower seal bilayer or multi-layer stator spacer disks, seals bilayer or multi-layer rotor spacer disks with going up on the motor shaft, inserts up and down and compresses the sealed screw rotation on the motor shaft, forms up and down apart from insulating space.

Because submersible pump is the oil immersed type motor, the motor cavity inner bearing is full of insulation lubricant oil, when the dive of air compression seal-free submersible pump, the disk air compresses to electric motor units in outside the formed space up and down, owing to be compressed the existence of resistance of air, the height in the feasible water restriction that enters in the disk is limited in necessarily; Because bilayer or multi-layer discs are isolated, and then improve many times of diving depths, add as long as the bottom float switch is reported to the police the closure prompting or middle and upper part secondary warning place, all be that air compression and the room alarming in the pump motor given security; Make water away from, can not enter electric motor units, end sealed member and prolong diving depth, reduce motor load and noise pollution thereby realize need not sound.

Beneficial effect of the present invention is:

The present invention is simple in structure, and using effect is good, and it can effectively stop the isolation of oil, water and improve diving depth, thereby realizes that water pump inpatient department does not have patient's prospect, saves a large amount of maintenance funds for global water pump subtracts carbon, also is the global people good thing of having run by the community.

Description of drawings;

Fig. 1 is a structural representation of the present invention.

The examination of concrete enforcement side:

As shown in Figure 1; Of the present invention going up inhaled multilayer spacer disks air compression seal-free submersible pump, it is by the electric motor units that is provided with from bottom to top in the housing 1, the impeller units that sealing unit is connected with described sealing unit offers water intake 2 being positioned on the housing of sealing unit; Offer water outlet 3 on described impeller units top; The motor shaft 4 of described electric motor units extends up in the impeller units, and the motor shaft that is positioned at impeller units is provided with impeller 5; Motor shaft 4 upper end caps 11 that are positioned at sealing unit are provided with lower seal bilayer or multi-layer stator spacer disks 6,7; Seal bilayer or multi-layer rotor spacer disks 8,9 with going up on the motor shaft; Insert up and down and compress sealed screw rotation, compressed air insulating space in the formation on the motor shaft.

Motor in the described electric motor units 1 is the oil immersed type motor, owing to be full of insulating oil in the motor, reduces the air in the motor cavity like this; When the dive of air compression seal-free submersible pump, after the degree of depth of setting, point out alarm or middle and upper part 7 secondary warnings place with closure at upper end cap 11 upper floating ball induction switches 10, all be that air compression and the room alarming in the pump motor given security; Add to form and go up lower rotor part spacer disks 8,9 on compressed air space and bilayer or the multilayer, and then significantly improve diving depth, make water away from, can not enter electric motor units, end sealed member and prolong diving depth thereby realize need not sound, reduce motor load and noise pollution, thereby realize that water pump inpatient department does not have patient's prospect, save a large amount of maintenance funds for global water pump subtracts carbon, also be the global people good thing of having run by the community.
