Abstract
The utility model provides a novel self-sucking pump, which has a water tank, the bottom of which is connected and equipped with a liquid-in pipe, the side wall of the water tank is connected and equipped with a liquid-out pipe, a positive vane wheel driven by the motor axle is provided on the upper of the liquid-in gob of the water tank, a vortex shell is sleeved on the outside of the positive vane wheel, the upper surface of the water tank matches to the motor axle and is equipped with a seal device, the utility model is characterized in that the vortex shell is a double flow passage vortex shell with a structure of symmetry double helix flow passage. A deputy vane wheel is fixed and equipped on the upper part positioned on the inner part of the water tank positioned on the motor axle. The seal device seals by the method of matching between the rotor ring and the stator ring end face. The good effects of the utility model are that the double flow passage vortex shell is used, the agent is thrown from two opposite directions, the motor axle receives a radial force compensating each other, thereby reducing the vibration. The deputy vane wheel of the motor axle is provided on the upper of the deputy vane wheel and the negative pressure is formed, the condition of the agent flowing into the upper of the deputy vane wheel is prevented, the seal effect is achieved. The seal manner of automatically compensating the rotor ring and stator ring end face is utilized between the upper surface of the water tank and the motor axle, the seal property is enhanced.
Description
Technical field:
The utility model relates to a kind of improvement of self-priming pump, particularly a kind of improvement of vertical self-sucking pump.
Background technique:
At present, self-priming pump finds broad application in departments such as environmental protection, fire-fighting, agricultural, chemical industry.Self-priming pump commonly used adopts the self-priming mode of gas-liquid mixed formula more, promptly be earlier with after gas and the liquid mixing, to separate in the gas from liquid through gas-liquid separator, the self-priming pump mechanism complexity of this structure is when stopping, be easy to generate siphonage, medium is missed from pump chamber easily, waits next time start time, still needs injected media in the pump, do not reach the effect of " drainage, lifelong self-priming ".Simultaneously because this kind self-priming pump adopts the volute single channel, radial force that can not the balance pump shaft, in the time of machine works vibrations big, pump housing loss is big.The seal arrangement of this kind self-priming pump all adopts mechanical seal, and sealability is difficult to be guaranteed.
Summary of the invention
The utility model provides a kind of self-priming pump, and its purpose is to overcome the prior art shortcoming, and can realize the effect of " drainage, lifelong self-priming ", good seal performance, and the work vibrations are little, and pump housing loss is little, and is simple in structure, the self-priming pump that reliability is high.
For realizing goal of the invention, adopt following technological scheme:
A kind of self-priming pump, has water tank, water tank bottom connects establishes liquid inlet pipe, the water tank sidewall connects establishes drain pipe, the top of liquid entering hole is provided with by the shaft-driven positive impeller of motor in the water tank, be arranged with volute outside the positive impeller, the water tank upper surface cooperates motor shaft to be provided with seal arrangement, and it is characterized in that: described volute is the double flow channel volute with symmetric double helical flow path structure.
The top that is positioned at the water tank part at motor shaft also is installed with sub-propeller.
Above-mentioned seal arrangement is, water tank upper surface wound motor axle is installed with stationary seat, be installed with stationary ring on the stationary seat, be arranged with rotating seat on the motor shaft, the rotating ring that sets firmly on the rotating seat cooperates the formation end face seal with the stationary ring end face, between rotating seat and motor shaft seal ring is set, has the protruding wall established on spring one end contact rotating seat, the other end contact motor shaft, cooperate with the stationary ring end face with the pushing and pressing rotating ring.
The usefulness of technique scheme is: adopt the double flow channel volute, medium throws away from opposite both direction, the radial force that motor shaft is cancelled each other and reduced vibrations.Sub-propeller on the motor shaft is arranged on the sub-propeller top and forms negative pressure, stops medium to flow into the top of sub-propeller, reaches sealing effect.Adopt the rotating ring stationary ring end face seal mode that can compensate automatically between water tank upper surface and the motor shaft, improved sealability.
