Description
Technical Field
The utility model relates to the technical field of submerged pumps, in particular to a high-lift all-plastic submerged pump.
Background
With the development of global economy and the continuous progress of the technical level of manufacturing technology of chemical centrifugal pumps, the demand of submerged pumps is increasing year by year. The submerged pump is widely applied to steel, petroleum, chemical industry, papermaking, environmental protection, nonferrous metals, acid regeneration pit and tank material transportation, and for the fluid occasion with strong corrosiveness and more impurities, the submerged pump works, because the rotating impeller works on the liquid, the pressure of the liquid in the pump is higher than the environmental pressure outside the pump, so that the liquid in the pump leaks outside the pump from the gap between the pump body and the rotating shaft, and the submerged pump is more easy to leak particularly aiming at high lift. In order to prevent or reduce the leakage amount of the medium, a shaft seal (a sliding bearing) is arranged below the liquid level of the plastic submerged pump generally, but in the magnesium chemical industry, the lift of the submerged pump exceeds 100 meters (1.0 Mpa), so that the leakage amount of the submerged pump is greatly increased, the vibration amount of the pump is seriously exceeded, and the working state of the pump is unstable. In order to solve the defects of the existing submerged pump, it is particularly necessary to design a high-lift all-plastic submerged pump higher than 100 meters.
Disclosure of Invention
Aiming at the defects existing in the prior art, the utility model aims to provide the high-lift all-plastic submerged pump which has the advantages of simple structure, reasonable design, high lift and good corrosion resistance, can keep a stable working state in various severe environments, has longer service life, strong practicability and is easy to popularize and use.
In order to achieve the above object, the present utility model is realized by the following technical scheme: the high-lift all-plastic submerged pump comprises a pump shell, a pump cover, an impeller, a balancing device and a power seal, wherein the pump shell is connected with the pump cover to place the impeller in a sealing cavity, the impeller is arranged at the shaft end of a pump shaft, a shaft sleeve for fixing the position of the pump cover is arranged on the pump shaft corresponding to the pump cover, and the power seal is arranged at the joint of the shaft sleeve and the pump cover; the pump shell is provided with a balancing device.
Preferably, the balancing device adopts a double-balancing plate structure of a first balancing plate and a second balancing plate, and is sleeved and fixed on the pump shell; the balancing device can lighten or even eliminate the condition that the vibration of the plastic submerged pump is increased due to the impact of high pressure in the pump cavity, and improves the stability of the pump body.
Preferably, the pump shell, the pump cover and the impeller are all made of high-strength and high-corrosion-resistance plastics, and are formed by one-step compression molding with mold plastics under high pressure, so that the pump can be used under various severe working conditions.
The utility model has the beneficial effects that: the device has high lift and good corrosion resistance, can work in various severe environments, keeps a stable working state, has longer service life, greatly expands the use parameter range of the plastic submerged pump, expands the use industry of the plastic submerged pump, and has wide application prospect.
