Abstract

The utility model relates to a dry-running sewage submersible pump with a dirt separator, which is characterized by comprising an impeller, a pump body, a separator, a separation chamber, an impellerblade, a flanged base, a pump cover, an oil chamber, a seal gasket, a cooling enclosure, a motor, a motor shell, a rotating spindle, a mechanical seal, a seal ring and relevant connecting components.Compared with the prior art, with the functions of water cooling, dirt separation, mechanical seal for direct spraying of clean water and dry running on the land, the utility model improves the efficiency of the pump, prolongs the service life of the pump, and widens the application scope of the pump.

Description

The operation the done sewage submersible pump of band dirt separation
Technical field
The utility model relates to a kind of industry and municipal water pump, the especially a kind of operation done sewage submersible pump with dirt separation.
Background technique
In the prior art, there is following shortcoming in the sewage submersible pump: 1, the sewage submersible pump all is to rely on the water body pumped that motor is cooled off, and crosses when low when water level, and the sewage submersible pump perhaps causes burn-down of electric motor owing to can't cool off and cisco unity malfunction; 2, in some occasion, require the sewage submersible pump can place land to carry out work, at this moment, general sewage submersible pump just can not use.
Summary of the invention
The purpose of this utility model is will provide a kind of to have from the sewage submersible pump that cools off function, and can separate the dirt in the sewage that enters cooling chamber, stop dirt to enter cooling chamber, guarantee can not make cooling failure owing to dirt enters cooling chamber, and can be installed in land and carry out the dryness operation, solved following technical problem: 1, cross when low when water level, the sewage submersible pump perhaps causes burn-down of electric motor owing to can't cool off and cisco unity malfunction; 2, in some occasion, require the sewage submersible pump can place land to carry out work, at this moment, general sewage submersible pump just can not use.
The utility model mainly is the cooling system certainly with pressure source and pressure difference that is provided with on the sewage submersible pump, and at the place, cooling water inlet dirt separation is set, and at the water inlet of sewage submersible pump general adpting flange is set.The operation the done sewage submersible pump of described band dirt separation is by impeller, the pump housing, separator, disengagement chamber, the impeller back blades, flange base is arranged, pump cover, the grease chamber, seal ring, cooling cover, motor, motor housing, rotary main shaft, mechanical seal, seal ring and associated fitting are formed, it is characterized in that: cooling cover is equipped with in the outside of the motor housing of described motor, seal ring is housed between the two, the lower end of motor housing connects the grease chamber, the lower end of grease chamber connects pump cover, motor housing wherein, pump cover and grease chamber are drilled with cooling intake tunnel and cooling for reflux passage, the lower end of pump cover connects the pump housing, the lower end of the pump housing is connected with flange base, impeller is contained in the rotary main shaft end of motor, separator is equipped with at the back blades cylindrical place at the impeller back side, the pump housing and pump cover are provided with disengagement chamber, the type shape of its inwall matches with the outer rim of separator, be provided with the gap between disengagement chamber and the separator, on the rotary main shaft between impeller and the pump cover mechanical seal is housed, the position of mechanical seal is over against the outlet port of cooling for reflux passage.
Working principle of the present utility model is: sewage is under the centrifugal action of impeller, sewage flows to the outer circular direction of impeller, most of sewage flows out pumping hole through the runner of the pump housing, the sewage of fraction will enter the cooling channel through separator, enter the effect that will be subjected to separator before the cooling channel, sewage is at centrifugal force, under the acting in conjunction of gravity and pressure, having the greater weight dirt can flow in the runner of the pump housing, flow out pumping hole with sewage, thereby stop dirt to enter cooling chamber, the water that assurance enters cooling chamber all is clear water, has guaranteed can not make cooling failure owing to dirt enters cooling chamber.Because the water intake of cooling intake tunnel is located at the upper end of impeller cylindrical, this place is the zone of high pressure in the pump, the outlet of cooling for reflux passage is then leaned on the center at the back side of impeller, this place is the low pressure area in the pump, like this, cooling water is just automatically entered by the opening of cooling intake tunnel, flow through cooling intake tunnel, cooling chamber and cooling for reflux passage, finally flow back to again in the pump housing, in pump, just formed the cooling system of self-loopa.Because the existence of self-circulation cooling system is improved efficiency of motor.Because this cooling system is a closed system, cooling water can not revealed outside pump, motor need not lean on the outer water body of pump to cool off, this sewage submersible pump can dryness be moved, but owing to be provided with general adpting flange in the water inlet of pump, pump can be installed and used on land, enlarged the using scope of sewage submersible pump.Spray because the cooling water that refluxes is aimed at mechanical seal, improved the souring and the lubricated cooling action of mechanical seal, thus the working life of having improved pump.
Description of drawings
Fig. 1 is the structural representation of the operation the done sewage submersible pump of band dirt separation described in the utility model.
Symbol description among the figure: 1 impeller, 2 pump housings, 3 separators, 4 disengagement chambers, 5 impeller back blades, 6 have seal ring, 16 grease chambeies, 17 mechanical seals, 18 seal rings, 19 rotary main shafts on flange base, 7 pump covers, 8 cooling intake tunnels, 9 cooling for reflux passages, 10 motors, 11 motor housings, 12 cooling covers, 13 cooling chambers, 14 lower seal, 15.
