Description
Technical Field
[0001] The utility model relates to the technical field of gear pumps, in particular to a combined gear pump housing. Background Technique
[0002] A gear pump is a rotary pump that relies on the change and movement of the working volume formed between the pump cylinder and the meshing gears to transport or pressurize liquids. It consists of two gears, a pump body, and front and rear covers to form two closed spaces. When the gears rotate, the volume of the space on the side where the gears disengage changes from small to large, creating a vacuum to suck in the liquid. The volume of the space on the side where the gears mesh changes from large to small, squeezing the liquid into the pipeline. The suction chamber and the discharge chamber are separated by the meshing line of the two gears. The pressure at the discharge port of the gear pump completely depends on the resistance at the pump outlet.

A sealing rubber ring 104 is provided at the connection to ensure the sealing performance after assembly.
[0026] Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5As shown in the figure, a combined gear pump housing, a vibration damping and fixing component 2, includes an upper fixing block 201, a lower fixing block 202, a first vibration damping pad 203, a connecting bolt 204, and a connecting block 205. An installation and support component 3, a control rod 302, a threaded rod 303, a fixed base 304, an installation plate 305, an installation hole 306, and a second vibration damping pad 307, includes a rotating seat 301. The pump housing assembly 1 can be firmly fixed through the fixed base 304. The first vibration damping pad 203 is closely attached to both the upper fixing block 201 and the lower fixing block 202, and the material of the first vibration damping pad 203 is set as an ACF extreme buffer material. The upper fixing block 201 and the lower fixing block 202 form a thread-detachable structure through the connecting bolt 204, and two lower fixing blocks 202 are symmetrically arranged about the vertical central axis of the connecting block 205. The control rod 302 forms a rotating structure with the threaded rod 303 through the rotating seat 301, and the rotating seat 301 is threadedly connected to the threaded rod 303. The installation holes 306 are equidistantly arranged inside the installation plate 305, and two installation plates 305 are symmetrically arranged about the vertical central axis of the fixed base 304.
