Abstract
The utility model discloses a novel wear-resistant mud pump which comprises a pump body, a pump shaft and an impeller. The pump shaft is arranged on the pump body, the impeller is arranged at one end of the pump shaft, a water flushing device is arranged at the entrance end of the pump body, and a wear-resistant liner ring is fixed on the pump body. By utilizing the wear-resistant liner ring, the axial matching between the impeller and the pump body is changed into the radial matching between the wear-resistant liner ring and the impeller; the liner ring is made of high-alloy wear-resistant materials; therefore, the service life of the mud pump is greatly prolonged; once wear is incurred between the wear-resistant liner ring and the impeller, the clearance between the wear-resistant liner ring and the impeller can be adjusted by a bolt, and the disassembling maintenance does not need to be carried out. The novel wear-resistant mud pump is widely applied in aspects of channel dredging, mud blowing, land forming, embanking, dredging of urban sewage pipelines, conveying of various slurries, and the like.
Description
Technical field:
The utility model relates to a kind of pump, particularly relates to a kind of dredge pump of carrying mud or slip.
Background technique:
In waterway dredging, blow that mud is built up fields, the aspects such as desilting of fill and urban sewage pipe all will use various dredge pumps, the dredge pump that is adopted has removing sludge and slag stock pump in the market, the suction that adopts the pump impeller rotation to be produced is drawn silt, slip or foreign material.Because the concentration height or the particle of silt, slip or the foreign material inhaled are big, cause the overcurrent part of pump easy to wear, wearing and tearing occur, can cause the gap occurring between the impeller and the pump housing in case flow passage divides, the suction of pump can descend greatly like this, causes the working efficiency of pump to reduce greatly.Between the pump housing and impeller, increase by two wear-resisting grommets for this reason, change impeller and radial fit between the pump housing into axial cooperation between the wear-resisting grommet, the working life of having improved pump so greatly.Adopt this structure to have following shortcoming: 1. the gap between the pump housing and the impeller can't be adjusted, and can have influence on the suction of pump after long-time the use; 2. two wear-resisting grommets adopt axially and cooperate, and make the installation difficulty of pump, in case both coaxalitys do not reach noise and vibrations that the designing requirement meeting increases pump, can influence the working life of pump on the contrary.
The model utility content:
The purpose of this utility model is to provide a kind of dredge pump of new structure, and wear-resisting grommet is set on the described pump housing, by adjusting the purpose that radial fit precision between wear-resisting grommet and the impeller reaches the working life of improving dredge pump.
The utility model is achieved in that a kind of novel wear resistant dredge pump, comprise the pump housing, pump shaft and impeller, described pump shaft is installed on the described pump housing, described impeller is installed in an end of described pump shaft, entrance point at the described pump housing is provided with flushometer, it is characterized in that: be fixed with a wear-resisting grommet on the described pump housing.
The utility model compared with prior art has following advantage:
1. owing to adopt wear-resisting grommet, with the axial radial fit that changes between the wear-resisting grommet impeller that cooperates between impeller and the pump housing, grommet is made by heavy alloyed high-abrasive material, has improved the working life of pump so greatly.
2. because the distance between impeller and the wear-resisting grommet can be adjusted, can adjust between the two gap by bolt, need not dismounting and keep in repair in case occur wearing and tearing between the two.
3. adopt the dredge pump of this structure to have characteristics simple in structure, easy installation and removal, reduced the noise and the vibrations of pump simultaneously.
4. owing to the entrance point at the pump housing is provided with flushometer, one side utilizes the pressure of water to reduce the concentration of flow medium, improves the efficient of carrying; The medium dissolves of utilizing the rotation of water and impeller to harden on the other hand reduces its wearing and tearing to pump housing overcurrent part, reduces the maintenance and the maintenance number of times of dredge pump, the working life of improving dredge pump.
