Description
Technical field
The utility model belongs to centrifugal pump manufacturing field, and in particular to a kind of noise-proofing centrifugal pump of horizontal axis.
Background technology
At present, in Chemical Manufacture, in order to meet the requirement of process conditions, it is necessary to which fluid to be sent to another place at one,
This just needs the equipment that energy is provided for fluid, fluid is obtained pressure energy and kinetic energy, it is necessary to using centrifugal pump, at present, known
Centrifugal pump be all made up of base, the pump housing, impeller, main shaft and motor etc., some large centrifugal pumps are during work, meeting
Larger noise is produced, and then human body is damaged.
Utility model content
In order to solve the deficiencies in the prior art, the utility model provides a kind of noise-proofing centrifugal pump of horizontal axis.
The utility model is achieved through the following technical solutions.
A kind of noise-proofing centrifugal pump of horizontal axis, including the pump housing, impeller, motor, the impeller is connected with inter-axle shaft, after described
Power transmission shaft is connected with middle power transmission shaft, and the middle power transmission shaft is connected with front propeller shaft, and the front propeller shaft is connected with motor, before described
Power transmission shaft and inter-axle shaft are fixed by sliding bearing, and the pump housing includes charging aperture, discharging opening, contains a water on the pump housing
Level, level meter insertion are installed in the groove of the pump housing, are provided with pressure gauge on the discharging opening pipeline, outside the motor
Portion is cased with noise-proofing shield, and the noise-proofing shield is fixedly connected by screw with centrifugal pump support.
Specifically, above-mentioned front propeller shaft is identical with the nominal diameter of inter-axle shaft, and the middle power transmission shaft is plug-in type with before
Power transmission shaft connects with inter-axle shaft.
Specifically, the maximum range of above-mentioned pressure gauge is 12bar.
Specifically, above-mentioned noise-proofing shield is made up of trilaminate material, and internal material is quality of rubber materials, and intermediate materials are stainless
Steel material, exterior material are quality of rubber materials, and the stainless steel is bonded with quality of rubber materials using glue.
Technical scheme more than, the beneficial effects of the utility model are：
Centrifugal pump provided by the utility model, outside motor contain noise-proofing shield, can effectively reduce centrifugal pump mistake
Caused noise in journey, reduces noise pollution, and and can effectively prevents the liquid corrosion that motor surface is dripped, extends motor
Service life；Centrifugal pump is during operation, and such as if not horizontal positioned, impeller and pump shaft easily damage, the peace of level meter
Whether horizontal positioned dress, can observe centrifugal pump constantly；After the installation pressure gauge of discharging opening, discharge pressure can be monitored constantly, is prevented
Discharge pressure is excessive, and centrifugal pump is caused to damage；Power transmission shaft in the utility model is three-level power transmission shaft, can when pump damages
Power transmission shaft is taken apart, so cause motor separated with the pump housing, for ease of maintenaince when carried.
Brief description of the drawings
In order that the purpose of this utility model, technical scheme and advantage are clearer, below in conjunction with accompanying drawing to this practicality
It is new to be described in further detail, wherein：
