Background technique
Submersible sewage pump is a kind of Pump and Electromotor disjunctor, and the pump series products worked under simultaneously slipping into liquid, in sewage disposal system, use comparatively extensive.Pollution discharge pump in the market generally comprises the pump housing, be arranged on motor in the pump housing and by motor-driven impeller.The seal arrangement of proof submersible sand discharging pump, due to the restriction by seal chamber structure, is all generally by two seals, namely adopts the combination of double mechanical seal and an outside framework oil seal; Outside framework oil seal is first sealing, and anti-sealing and impurities in water enter grease chamber; Double mechanical seal is second sealing, prevents liquid leakage in grease chamber from entering motor.
The outside framework oil seal of this proof submersible sand discharging pump directly contacts with rotating shaft, run up in process in pollution discharge pump rotating shaft, easily cause the wearing and tearing of rotating shaft and the damage of outside framework oil seal, and then cause seepage to affect the working life of pump, and repair and bother very much, need the outside framework oil seal that dismounting lower pump body, impeller and rotating shaft just can more renew, the pollution discharge pump after again repairing easily occurs that the phenomenons such as coaxality difference rotating shaft play occur.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides a kind of rotating shaft not frayed, changes outside framework oil seal proof submersible sand discharging pump easily.
The purpose of this utility model realizes by following technical proposal: a kind of proof submersible sand discharging pump, comprise motor, impeller and the pump housing, the described pump housing has water intake and water outlet, the rotating shaft of described motor to be stretched in the pump housing and rotating shaft is fixed with the impeller being positioned at the pump housing, the housing of described motor is by upper end cap, motor housing and lower end cap are formed, described lower end cap is connected mutually with pump housing top, described upper end cap and be respectively equipped with bearing between lower end cap and machine shaft, oil pocket is provided with between described lower end cap and the pump housing, it is characterized in that, one end mask of described impeller has some equally distributed blades and the other end of impeller has the impeller handle of outwardly convex, outside framework oil seal is provided with between the outer side wall of described impeller handle and the pump housing, the part place that described rotating shaft is positioned at oil pocket is provided with mechanical seal device.
The outside framework oil seal of this proof submersible sand discharging pump contacts with the pump housing with impeller handle outer side wall; avoid outside framework oil seal directly to contact with machine shaft; protect machine shaft not by friction injury; as outside framework oil seal damages the words needing to change; only directly need unload the outside framework oil seal that impeller just can more renew, make it install simple and convenient.
In above-mentioned a kind of proof submersible sand discharging pump, described mechanical seal device comprises mechanical seal, lower mechanical seal and spring, described spring is between upper mechanical seal and lower mechanical seal, described upper mechanical seal is located between rotating shaft and motor lower end cap, and described lower mechanical seal is located between rotating shaft and the pump housing.
In above-mentioned a kind of proof submersible sand discharging pump, described pump housing bottom is connected with base, and described water intake to be positioned on base and to be connected with impeller, and described water outlet is positioned on the pump housing of impeller side.
Compared with prior art, it is not frayed that this proof submersible sand discharging pump has rotating shaft, and outside framework oil seal changes the advantages such as convenient.
