Description

Technical Field

[0001] The utility model belongs to the technical field of pump casings, and particularly relates to a pump casing cover. Background Art

[0002] Gear oil pumps are suitable for transporting various lubricating liquids, generally used at temperatures not higher than 200°C. As a power component of a hydraulic system, gear oil pumps have a wide range of applications. The installation dimensions of the power take-off ports of gear oil pumps are diverse. When connecting the same external pipe to the pump body with two or more chambers, a pump casing cover capable of connecting the chambers is required, and at the same time, it needs to have a liquid deceleration function to avoid the operation of the gear oil pump caused by a large difference in liquid flow velocity between the two chambers.

[0003] The patent document with the publication number CN209638100U discloses a front end cover of a pump body, a pump body, and a magnetic pump. The front end cover of the pump body includes an end cover body, an input pipe, an output pipe, and a positioning frame. A concave cavity is provided on one side of the end cover body. The input pipe and the output pipe are both arranged outside the end cover body and are both communicated with the concave cavity. The positioning frame extends from inside the input pipe into the concave cavity. The positioning frame includes a positioning table for connecting with the pump shaft and several supporting feet connected between the outer wall of the positioning table and the inner wall of the input pipe. A channel for communicating the concave cavity with the input pipe is formed by enclosing between the positioning table, the end cover body, and any two supporting feet. A first installation hole communicated with the concave cavity for cooperating with the pump shaft and a drain hole communicating the first installation hole with the input pipe are provided on the positioning table. In this utility model, the drain hole is communicated with the first installation hole on the positioning table, which can discharge the liquid flowing into the first installation hole, and at the same time, cool and reduce the temperature generated by the friction of the pump shaft, so that the entire magnetic pump can operate normally. However, this front end cover of the pump body lacks a liquid deceleration component between multiple chambers and is not suitable for use in a gear oil pump with multiple chambers.
