Description
Technical field
The present invention relates to the pump technology field, especially a kind of feed-water end need not to install the novel without the sealing vertical self-priming centrifugal pump of safety check.
Background technique
Existing vertical centrifugal pump, vertical self-priming centrifugal pump, nothing sealing vertical self-priming centrifugal pump etc. generally all need to be installed safety check or solenoid vacuum valve in import, the outlet port of the pump housing.At present, above-mentioned these a few class pump check valves are easier to damage usually, and solenoid vacuum valve also can break down because of the chronic infiltration of water, causes the working life of pump shorter.
Existing self priming centrifugal pump is in order to satisfy the self-priming demand, and often the self-priming demand is satisfied to increase moisture storage capacity in the position by raising suction port, proposes requirements at the higher level can for like this user's setting height(from bottom).It is basic between the pump housing and the motor that the radial force that pump bears and intermediate support are advocated and will be born by the built-in bearing of motor in order to be rigidly connected, therefore, long-play, the operating mode operation causes the electric machine built-in damage of bearings easily especially partially.The interior sealing of pump substantially all is to realize dynamic seal by sub-propeller, and sub-propeller only seals when pump normally moves, and often still leakage phenomenon can occur when pump deceleration or parking.
Summary of the invention
Deficiency for above existing self priming centrifugal pump, the purpose of this invention is to provide a kind of feed-water end and need not to install the novel without the sealing vertical self-priming centrifugal pump of safety check, set up anti-rotating plate in the gas-liquid separation chamber in the pump housing, can stop vane rotary to cause the parabola shaped rotation of air-water mixture, can accelerate gas-liquid separation, the working efficiency of Effective Raise pump behind the anti-rotating plate of air-water mixture bump.
The objective of the invention is by realizing by the following technical solutions:
Novel without the sealing vertical self-priming centrifugal pump, comprise the pump housing and motor, motor is connected with the pump shaft of the pump housing by coupling, the lower end of pump shaft is provided with impeller, the lower end of the described pump housing is provided with water-inlet cavity, and a side of the pump housing is provided with outlet pipe, and described water-inlet cavity is communicated with the water inlet body, the water inlet body connects intake pipe, and the connecting end of described intake pipe and water inlet body is higher than the entrance point of intake pipe.
As the preferred technical solution of the present invention, the top of described water-inlet cavity is provided with deflector, and described impeller is located in the deflector, and the deflector top is provided with anti-rotating plate, and anti-rotating plate is connected with the pump housing and fixes.
As the preferred technical solution of the present invention, be provided with submerged bearing between described pump shaft and the anti-rotating plate.
As the preferred technical solution of the present invention, be provided with dividing plate in the pump housing of described coupling below, be respectively equipped with outside framework oil seal and dynamic sealing device between dividing plate and the described pump shaft.
As the preferred technical solution of the present invention, described outlet pipe is made of supervisor, check valve and outer pipe, and supervisor is connected with the pump housing, and outer pipe is connected with supervisor by check valve, and the outlet end of described outer pipe is higher than the entrance point of described intake pipe.
As the preferred technical solution of the present invention, described motor is anti-explosion motor.
With respect to prior art, the present invention has following characteristics: 1, pump inlet increases moisture storage capacity in the situation of not raising the suction port position, can satisfy the self-priming demand; Prevent simultaneously siphon, siphonage can not the interior liquid storage of return pump during shutdown.Compare with conventional vertical self-sucking pump, pump inlet needn't be installed safety check or solenoid vacuum valve, thereby the life-span that has solved valve is short, the problem of poor reliability.
2, set up anti-rotating plate in the gas-liquid separation chamber in the pump, can stop vane rotary to cause the parabola shaped rotation of air-water mixture, can accelerate gas-liquid separation, the working efficiency of Effective Raise pump behind the anti-rotating plate of air-water mixture bump.
3, the sealing configuration that adopts the dynamic sealing of auxiliary impeller device to combine with outside framework oil seal, the leakage problem when having solved pump deceleration or shutdown.
4, increase submerged bearing, improve the reliability of pump.
The present invention combines the advantage of existing vertical centrifugal pump, vertical self-priming centrifugal pump, nothing sealing vertical self-priming centrifugal pump, has improved pump performance and working life.
