Worm gear pump with worm wheel gear cavity as working space

Abstract

The invention relates to a worm gear pump with a worm wheel gear cavity as a working space. The worm gear pump is characterized in that a worm gear transmission mechanism is arranged in a pump shell consisting of a worm rod shell and a worm wheel shell; a pump shell inflow passageway and a pump shell outflow passageway are arranged on the worm rod shell and respectively communicated with a corresponding worm rod inflow passageway and a corresponding worm rod outflow passageway which are arranged in a worm rod; a baffle is arranged between the worm rod inflow passageway and the worm rod outflow passageway; and a worm rod inflow hole communicated with a worm rod inflow channel and the cavity of the worm wheel shell is formed on the worm rod at one side of the baffle, and a worm rod outflow hole communicated with a worm rod outflow channel and the cavity of the worm wheel is formed on the worm rod at the other side. The pump provided by the invention has the characteristics of small noise, high and uniform pressure, uniform and continuous flow, wide flow range, large bearing capacity, high efficiency, small loss, wide variety and viscosity range of conveyed fluid materials and wide application, can be used for converting fluid energy into mechanical energy or converting the mechanical energy into the fluid energy and then converting the fluid energy into the mechanical energy to be converted into the fluid energy or be converted into the mechanical energy into the fluid energy and then converted into the mechanical energy.

Description

Worm gear pump with worm gear tooth cavity as working space technical field The invention relates to a pump, in particular to a worm gear pump with a worm gear tooth cavity as a working space. It is suitable for transporting liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals, etc. It is also suitable for transporting liquids, gas mixtures and liquids containing suspended solids. Background technique Usually, when transporting liquid or liquid-gas mixture and liquid containing suspended solids, there are many types of pumps used, and the gear pump is one of them. Composition, it discharges the inhaled material through gear transmission, so as to achieve the purpose of conveying the material. Although this gear pump is simple in structure, easy to manufacture, easy to maintain, and has self-priming ability, its flow rate, pressure pulsation and noise are large, and there is also the phenomenon of "trapped oil". A screw pump has ...

AI Technical Summary

Problems solved by technology

However, the processing and assembly of this kind of screw pump has high technical requirements, and the performance of the pump is sensitive to the viscosity change of the conveyed liquid material, so its application range is limited.
