Abstract
The utility model relates to a single-stage leak-free syrup pump, which comprises a pump body, a single-stage impeller, a principal axis, and is characterized in that: the reverse of the impeller is provided with a curved seal ring to match with the curved seal ring on the pump cover and then to form a decompressing chamber. Decompressing holes are arranged on the pump cover, while the decompressing chamber is connected with the water entry (22) of the pump body by water pipe. The pump is in a back-hatched structure, while the pump cover (6) is arranged between the pump body (1) and the hanger bracket (10). The curved seal ring on the pump cover single-stage leak-free syrup pump in the utility model can increase the sealing effect and at the same time block off the heat of the pump body from transmitting onto the hanger bracket and prolong the service life of the pump when the cooling chamber that is arranged inside the pump cover; and the decompressing chamber can reduce the pressure of the high-pressure liquid; the back-hatched structure can make the pump cover, impeller and parts of the hanger bracket dismantle when the pump body and pipeline system are not removed during repairing.
Description
Technical field
The utility model relates to a kind of single-stage does not have the leakage syrup pump.
Background technique
Existing Is type single-stage clear water centrifugal pump, structural feature are that the impeller back side and pump cover are control ring seal.Because choma is ring-like single face sealing, sealing effect does not reach requirement, and liquid easily leaks, and the pump internal pressure is too high and body is overheated, the working life of having reduced pump.
Goal of the invention
The purpose of this utility model is to overcome above-mentioned defective, provides a kind of and can improve sealing effect and increase the service life, overhaul easily and the single-stage that can be used for syrup does not have the leakage syrup pump.
The technical solution of the utility model is: comprise the pump housing, single-stage impeller, main shaft, it is characterized in that the impeller back side is provided with bent type seal ring, match, cooperate the back to form the underpressure chamber with bent type seal ring on the pump cover, pump cover is provided with vent, and the underpressure chamber is connected with pump housing water inlet water pipe.
Feature of the present utility model is that also pump is the rear opening structure, and pump cover is between the pump housing and suspension.The pump cover inner chamber is provided with cooling chamber, and two end connectors of water-cooling tube connect cooling chamber and machine capping respectively.This pump seal is a double mechanical seal.
Single-stage of the present utility model does not have the bent type seal ring apparatus that leaks on the syrup pump pump cover can improve sealing effect, and the pump cover inner chamber is established cooling chamber and acted on cooling mechanical seal, intercepts pump housing heat simultaneously and reaches on the suspension, prolongs the working life of pump; The impeller back side is provided with the bent type seal ring of bent type seal ring and pump cover and matches and form the underpressure chamber, and pressure is corresponding after through the underpressure chamber weakens (being depressurized the hole siphons away) for highly pressurised liquid; The rear opening structure, the motionless pump housing and pipe-line system just can be dismantled pump cover when making maintenance, and impeller and sprung parts keep in repair very convenient.
