Problems solved by technology

Due to the novel structure of the combination and the complex circuit, the traditional test bench cannot meet the application requirements.
At present, there is no special test bench for this new type of built-in variable speed pump, and because the integrated circuit of the variable speed pump, safety valve and constant pressure valve is complicated, it is necessary to manufacture a special test tool

Abstract

The invention provides a novel variable speed pump test bed tool. The tool comprises a tool body; the middle of the tool body is sleeved with a transmission shaft in running fit with the tool body; the output end of the transmission shaft is connected with an adapter sleeve; the end part of the adapter sleeve is fixedly connected with two bumps; a boss driven by the bumps to rotate is arranged between the adjacent bumps; a tested pump valve group is arranged on the tool body; the tested pump valve group comprises a driving gear; and the boss is fixedly connected to the driving gear. The tool is reasonable in design and convenient to operate; the novel variable speed pump valve group can be tested; the shortcoming of a single function due to the fact that a traditional test bed only tests an external pump is overcome, so that the technology is improved; and the tool has practicability.

Description

technical field [0001] The invention relates to a new type of variable speed pump test bench tooling and its working method. Background technique [0002] "Busy at both ends" is a new type of special construction machinery, which has the functions of front-end loading and rear-end excavation, and has the advantages of small size, flexibility, compactness and high efficiency. There are good application prospects in other fields. The variable speed pump is a key component of this type of mechanical equipment. Its function is to provide pressure for the torque converter and transmission hydraulic system on the one hand, and to realize cooling and lubrication for the components in the torque converter-transmission on the other hand. In the traditional variable speed system of construction machinery, the variable speed pump, safety valve and constant pressure valve are manufactured separately and installed separately. Due to the demand for miniaturization and integration, the s...
