Description
Technical field
The utility model belongs to a kind of pump, specifically is a kind of detachable type Piping Centrifugal Pumps.
Background technique
Piping Centrifugal Pumps is a kind of vertical pump, be directly installed in the pipeline, at present, adopt duplex bearing, bearing directly assembles with axle, motor is connected with shaft drive, and the pump housing and pump cover constitute the working room of pump, impeller, axle and bearing are the rotor of pump, the rotor of connecting base and bearing supporting pump, supporting adopts connecting base to be connected with motor cabinet between motor and the pump, is easily damaged parts by the mechanical seal in the pump, needs frequent replacing, bearing in the pump needs frequent maintenance, be lubricated etc., when pump is overhauled or changes mechanical seal and bearing, must be with motor, motor cabinet, electric wiring, connecting base, pump cover and impeller demolition leave, operating is very much inconvenience, particularly concerning the bigger pump of relative volume, tend to during on-site maintenance can't realize maintenance because there is not lifting gear.
The model utility content
The purpose of this utility model provides a kind of detachable type Piping Centrifugal Pumps, has the characteristics of machining accuracy height, steady, safe and reliable, the long service life of running, can finish daily maintenance comparatively easily.
The technical solution of the utility model is as follows:
The detachable type Piping Centrifugal Pumps, include the pump housing, pump cover, impeller, axle, support, motor, bearing support, it is characterized in that described pump housing both sides are respectively material feeding mouth and discharge port, and bore is identical, in the cavity that the pump housing and pump cover form impeller is arranged, impeller is installed in the axle head that passes pump cover, with material feeding mouth, discharge port is positioned on the same center line, and described bearing support is connected with pump cover by bolt, and axle is equipped with axle sleeve in the bearing support corresponding positions, be equipped with bearing in axle sleeve and the bearing support, a sealed cover is arranged on the bearing support, adopt mechanical seal, axle is connected with motor by elastic coupling flexible coupling, support is by bolt and motor, pump cover connects, and described bearing is furnished with tank filler sleeve and drain oil.
Described bearing is a roller bearing.
Described impeller adopts the hydraulic model of automatically balancing axial force, and mechanical seal adopts stainless steel, Tungsten carbite, fluorine rubber to make.
The utility model is vertical mechanism, and Installation and Debugging are comparatively convenient, and the motor of unique design and the pump housing adopt connected body to connect, concentricity height, machining accuracy height, and floor space significantly reduces, and has reduced construction investment.But the low speed Y2 series standard general-purpose machine of the prominent domestic manufacturer production of adapted operates steadily, noise is extremely low.But impeller adopts the hydraulic model of the fitst water automatically balancing axial force nineties, makes pump bearing and mechanical seal prolong greatly working life.Bearing in the motor shaft bearing all is furnished with tank filler sleeve and drain oil, and is very convenient to the maintaining of bearing.Detachable elastic coupling flexible coupling makes pump starting friction, noise free, and rotary component is provided with reliable safty shield, and Security is fabulous.Mechanical seal adopts materials such as stainless steel, Tungsten carbite, fluorine rubber to make, and high temperature resistant, high pressure, service life are long, and ne-leakage does not have wearing and tearing to axle, and the assurance working environment is clean and tidy.As long as unload elastic coupling flexible coupling, pump cover nut, can very light taking-up bearing support, assembly parties such as pump cover, pump shaft, impeller, change mechanical seal and impeller, and needn't dismantle motor, the pump housing and pipeline, easy to maintenance quick.
