Abstract
The invention discloses a pump body structure of an eccentric pump with a self-absorption structure. The pump body structure comprises a bottom plate on which a pump body is arranged, the front end of the pump body is provided with a front pump cover, the upper end of the pump body is provided with an upper pump cover and the rear end of the pump body is provided with a rear pump cover through an O-shaped seal ring; the rear end of the rear pump cover is provided with a connecting frame, one end of a pump shaft is provided with an impeller, and the pump shaft is provided with a mechanical moving ring. The pump body structure provided by the invention is uniform in flow, steady to operate and small in vibration; furthermore, a sealing structure is formed between the static ring and the mechanical moving ring, therefore the integral usability of the pump body can be improved.
Description
Technical field
The present invention relates to centrifugal pump field, specifically belong to the pump body structure of self-absorbing structure centrifugal pump.
Background technique
What the essential structure of centrifugal pump was made up of six parts is impeller respectively, the pump housing, pump shaft, bearing, seal ring, stuffing box.1, impeller is the core of centrifugal pump, and its rotating speed high output is large, and the blade on impeller plays Main Function again, and impeller will be tested by static balancing before assembly.Inner and outer surface on impeller requires smooth, to reduce the frictional loss of current.2, the pump housing also claims pump case, and it is the main body of water pump.Play support fixation, and be connected with bearings mounted bracket.3, the effect of pump shaft borrows coupling to be connected with motor, and impeller is passed in the torque of motor, so it is the critical piece transmitting mechanical energy.4, rolling bearing uses clean oil to make oiling agent, refuels oil level line.Too many oil will ooze out along pump shaft, very little bearing again overheated burning out cause the accident.The highest at 85 degree in the temperature of water pump operation process middle (center) bearing, generally operate in about 60 degree.
Centrifugal pump can be widely used in the slurry of the industry conveyings such as electric power, metallurgy, coal, building materials containing solid particle.As thermal power plant's hydraulic(-ash) sluicing, technics of metallurgy mineral dressing factory pulp conveying, coal washery coal slurry and dense medium conveying etc.At present, centrifugal pump also exists complex structure, volume is large, Installation and Debugging are inconvenient, Flow-rate adjustment inaccuracy.
Summary of the invention
The object of this invention is to provide a kind of pump body structure of self-absorbing structure centrifugal pump, uniform flow, smooth running, vibration are little, are sealed between rotating ring and form sealing configuration, improve the overall usability of the pump housing by stationary ring and machine.
Technological scheme of the present invention is as follows:
The pump body structure of self-absorbing structure centrifugal pump, include base plate, base plate is provided with the pump housing, pump housing front end is provided with front pump cover, pump housing upper end is provided with pump cover, pump housing rear end is provided with rear pump cover by O RunddichtringO, and rear pump cover rear end is provided with link press span, and the end of pump shaft is provided with impeller, pump shaft is installed organic envelope rotating ring, rear pump cover is gripped with stationary ring by machine sealed cover, and stationary ring and machine seal between rotating ring and form sealing configuration, and pump shaft is connected by coupling with motor.
In the described pump housing, guide plate is installed.
Uniform flow of the present invention, smooth running, vibration are little, are sealed between rotating ring and form sealing configuration, improve the overall usability of the pump housing by stationary ring and machine.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
