Embodiment 1

[0026] figure 1 , figure 2 , image 3 Among them, the pump casing is formed by connecting the worm casing 3 and the worm gear casing 9 as a whole. The two ends of the worm casing 3 are respectively provided with a pump casing inflow channel 14 and a pump casing outflow channel 6 . A worm 1 connected to its bearing is arranged in the worm case 3, which meshes with the worm wheel 10 located in the worm case 9 and connected to the worm case 9 through the worm shaft 11, and forms a pump between the worm wheel 10 and the worm case 9. The working space is divided into expansion space 12 and compression space 8 at the meshing place of worm screw 1 and worm wheel 10 . In the worm 1, a worm inlet passage 13 and a worm outlet passage 7 are arranged along its axis, and the axial centerlines of the two are in the same direction as the axial centerlines of the pump casing inlet passage 14 and the pump casing outlet passage 6. coincide. And between the worm inlet passage 13 and the wo...

Embodiment 2

[0028] Figure 4 , Figure 5 , Figure 6 Among them, the worm 1 is a transmission shaft worm connected as a whole with the transmission shaft. The worm inflow channel 13 and the worm outflow channel 7 arranged in the worm 1 along the axial direction of the worm 1 and separated by the partition plate 4 are closed, while the worm gear casing 3 is arranged in the worm wheel housing 3 and arranged perpendicular to its axial direction. The pump casing inlet passage 14 and the pump casing outlet passage 6, the axial centerlines of both of them are perpendicular to the axial centerlines of the worm inlet passage 13 and the worm outlet passage 7, and the pump casing inlet passage 14 passes through the inlet port 15 It communicates with the worm inlet flow channel 13 , while the pump casing outlet flow channel 6 communicates with the worm screw outlet flow channel 7 through the outlet port 16 . And the worm gear shaft 11 is located in the worm gear housing 9 and is connected with it...

Embodiment 3

[0030] Figure 7 , Figure 8 , Figure 9 Among them, the worm 1 is an arc worm, and the pitch circle surface of the worm is the surface of the arc turning body obtained by revolving around the axis of the worm 1 with a segment of the 10 pitch circles of the worm wheel. Others are all the same as in Example 1. This kind of pump with worm gear as the transmission mechanism has large load capacity, high efficiency and low wear.

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

technical field [0001] 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 [0002] 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 also been used, which consists of a pump casin...
