Abstract
The utility model discloses a submersible sewage pump equipped with a muddy sand prevention device, and the submersible sewage pump comprises a pump body (1), an impeller (2), a pump cover (3), a pump base (4), a motor part (5), a junction box cover (6), an upper end cover (7), a hoisting device (8), an oil chamber (9), a double-section mechanical seal (10) and a muddy sand prevention device (11), wherein the muddy sand prevention device (11) is a group of inner skeleton polytetrafluoroethylene sealing elements which are inclined upwards, the inner side of the muddy sand prevention device (1) is circumferentially in a multi-lip shape, lip reinforcements obliquely extend towards the outer side, the muddy sand prevention device (11) is installed inside the pump cover in a pressing way, and a lip is closely matched with a shaft. Due to adopting the submersible sewage pump equipped with the muddy sand prevention device, the problems a movable ring and a stationary ring in dual-end mechanical seal are easy to damage and the motor is easy to burn can be solved; the repairing rate is reduced, and the running efficiency of a set is improved; and the cost is reduced, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of proof submersible sand discharging pump, specially refers to a kind of proof submersible sand discharging pump that has designed the anti-device for silt of the anti-device for silt configuration of lip structure at pump cover.
Background technique
Proof submersible sand discharging pump mainly is applicable to the industries such as municipal engineering, industrial or agricultural, hospital, building, hotel, for delivery of band solid particle and various long stapled waste water, city domestic sewage and rainwater, also comprise conveying, aquaculture, irrigation of former water etc., at present domestic to discharging bore 50～200mm, the pollution discharge pump of power 1.1～55kW, mostly adopt one double mechanical seal on the structure, mainly there is the defective of the following aspects in this kind pump type structure: (1), easily generation leakage make sewage enter into the chamber, grease chamber; (2), the fragile machine of the silt particle in the sewage seals dynamic and static ring; (3), motor easily damages; (4), unit operation is unstable, efficient is low.
Be illustrated in figure 1 as at present common a kind of proof submersible sand discharging pump, this structure pump is mainly by the pump housing 1, impeller 2, pump cover 3, pump seat 4, motor component 5, connector cover 6, upper end cap 7, boom hoisting 8 component such as grade form, because proof submersible sand discharging pump is mainly used in the sewage occasion, composition more complicated in the sewage, the content of silt particle is larger in the overwhelming majority sewage, during the pump high speed operation, because what adopt is one double mechanical seal, the solid particle of medium such as silt particle etc. are because the effect (chamber pressure that pump cover and impeller form is greater than the pressure in chamber, grease chamber) of centrifugal force, can be by the gap between axle and the pump cover, seepage enters chamber, grease chamber (easily entering damage machine envelope district for silt particle such as the A place among Fig. 1), thereby damage the moving of mechanical seal, stationary ring, and then use sewage to enter into motor cavity, burn out motor, so this structure pump assembly fluctuation of service, repair rate is high, is necessary to improve.
The model utility content
For the problems referred to above, main purpose of the present utility model is to provide a kind of proof submersible sand discharging pump that has designed the anti-device for silt of the anti-device for silt configuration of lip structure at pump cover.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of proof submersible sand discharging pump that configures anti-device for silt, described proof submersible sand discharging pump comprises the pump housing, impeller, pump cover, pump seat, motor component, connector cover, upper end cap, boom hoisting, grease chamber and double break face mechanical seal, described proof submersible sand discharging pump also comprises anti-silt device, described anti-silt device is one group of inner frame teflon seal obliquely, its inner circumferential is many lips shape, the lip muscle is extending obliquely laterally, this part is fitted in the pump cover, and the axle of lip and proof submersible sand discharging pump closely cooperates.
Positive progressive effect of the present utility model is: the proof submersible sand discharging pump of the anti-device for silt of the configuration that the utility model provides has the following advantages:
(1), solved the problem of the easy damage of the dynamic and static ring of both-end mechanical seal and motor easy burn-out;
(2), reduced repair rate, improved unit operation efficiency;
(3), reduced cost, improved working life.
Description of drawings
Fig. 1 is the structural representation of existing similar technology.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the partial enlarged drawing of Fig. 2.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
Fig. 2 is structural representation of the present utility model, Fig. 3 is the partial enlarged drawing of Fig. 2, shown in Fig. 2 and 3, the utility model comprises the pump housing 1, impeller 2, pump cover 3, pump seat 4, motor component 5, connector cover 6, upper end 7, boom hoisting 8, grease chamber 9 and double break face mechanical seal 10, this proof submersible sand discharging pump also comprises anti-silt device 11, anti-silt device 11 is one group of inner frame teflon seal obliquely, its inner circumferential is many lips shape, the lip muscle is extending obliquely laterally, this part is fitted in the pump cover, and lip and axle closely cooperate.
The utility model mainly is to have designed the anti-device for silt of lip structure at pump cover, the sealing device is a kind of special inner frame teflon seal, its inner circumferential is many lips shape, the lip muscle is extending obliquely laterally, unique structural design guarantees that the lip muscle is under the extruding of sewage and dirt, the multi-lip seal mouth is held pump shaft tightly, be compaction, and water pressure and impact force are larger, sealing effect is better, seal structure can effectively be kept off the suspended matter that blocks in the sewage, silt particle, the large particle thing prevents that them from entering grease chamber's mechanical seal mouth, damages the moving of mechanical seal, stationary ring, thereby burn out motor, because this part material has adopted teflon, thereby more wear-resisting, corrosion-resistant, long service life.
(1), solves the dynamic and static ring of both-end mechanical seal and easily damaged the problem of motor easy burn-out
(2), reduced repair rate, improved unit operation efficiency.
(3), reduced cost, improved working life.
Above demonstration and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
