Description

Anti-gas-resistance submersible pump with filter

Technical Field

The utility model relates to the technical field of liquid pumps, in particular to an anti-gas-resistance submersible pump with a filter.

Background

The submersible pump is used as a submerged pump for transporting liquids such as oil products, and the positive pressure pushing principle is utilized, so that the problem that negative pressure working pump bodies such as a pipeline pump, a displacement pump and a vane pump are difficult to meet the requirements of high-temperature environment, high lift and long-distance conditions is fundamentally solved, and the submersible pump is commonly used in an oil storage tank of a gas station and provides power for refueling the gas station. Liquid upwards discharges after the impeller accelerates from diving oil pump bottom suction pump in, when diving oil pump bottom suction oil, the partial pressure of diving oil pump bottom reduces, the air of dissolving in the oil is separated out and is produced bubble and partial oil vaporization and all can produce a large amount of bubbles, and this kind of condition is especially common under the summer high temperature condition, the bubble gets into diving oil pump and can produce the air resistance phenomenon, cause the flow reduction of diving oil pump and even appear cutting off, influence diving oil pump's life, cause economic loss for filling station.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the defects of the prior art and provides the gas-resistance submersible pump with the filter, which can prevent the submersible pump from cutting off due to the fact that air bubbles enter the submersible pump, greatly reduce the generation of gas resistance in the submersible pump, effectively prevent impurities in liquid from entering the submersible pump and prolong the service life of the submersible pump.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the gas-resistance submersible pump with the filter is characterized in that the filter is arranged on a motor bottom cover of the gas-resistance submersible pump; the filter is the tubular structure, and the top end opening of filter, bottom are sealed, and the lateral wall is provided with the filter screen, and on the filter screen top was fixed in the motor bottom of preventing the air resistance submersible pump through the bolt, equidistant a plurality of support bars that are provided with on the filter screen. Preferably, the filter is set to 90mm in diameter and 100mm in height.

Preferably, the filtering gap of the filtering net is set to 1 mm.

Preferably, the height of the supporting bar is set to be 100mm, and the width is set to be 5 mm.

Preferably, the filter screen and the supporting bars are made of metal materials.

The utility model has the following beneficial technical effects:

the filter is arranged on the bottom cover of the motor of the submersible pump, so that bubbles in an oil product are effectively prevented from entering the impeller of the submersible pump by utilizing a compact filtering gap on the filter, the oil inlet amount of the submersible pump cannot be reduced, the flow rate of the submersible pump is ensured, meanwhile, the filter arranged at the bottom of the motor of the submersible pump can also effectively filter impurities in the oil product, the impurities are effectively prevented from entering the motor of the submersible pump, and the service life of the submersible pump is prolonged.
