Problems solved by technology

[0003] However, the structure of the existing hydraulic control system based on the hydraulic pump performance test is not perfect, and there are still certain defects:
[0004] 1. Under the premise of testing the performance of the hydraulic pump, it is necessary to ensure that the hydraulic pump is measured in a stable environment. If the position of the hydraulic pump changes during the test, it will lead to inaccurate detection accuracy due to the unstable detection state during the test, which will affect the test. effect, and the instability of the specific position of the hydraulic pump cannot be quickly judged
[0005] 2. During the detection process, since it is impossible to ensure in real time whether there are impurities in the oil and water installed in the fuel tank, if the impurities enter the oil pipe, it will easily block the pipeline, which will have a great impact on the detection process. If the filter cannot be cleaned regularly, It will shorten the service life of the device and has certain limitations
[0006] 3. During the pressure detection process, the operator judges the pressure value through the data display, but cannot confirm the detection result manually at the same time. If the collected information is wrong, the operator cannot quickly judge it, thus affecting the accuracy of the detection result

Abstract

The invention relates to the technical field of hydraulic control systems, in particular to a hydraulic control system based on a hydraulic pump performance test. The hydraulic control system comprises an oil tank, a hydraulic pump group, a valve group, a water cooling tank, a mounting head, an oil inlet pipe, a fixing base, a drawing box, a fixing base, pressure blocks, a water absorption cotton piece, a feeding opening, a limiting plug, an oil outlet pipe, a filter, a stretching net, a pull handle, a telescopic rod, scraping bristles, a clamping block, a recording plate, a sliding rail, a scraping plate, a handle, a limiting sleeve, a data display screen and a warning lamp, wherein the pressure blocks are uniformly distributed; when the hydraulic pump group operates to generate vibration, the generated vibration sense can be buffered through cooperation of the multiple pressure blocks, so that the stability of the hydraulic pump set is kept, the water absorption cotton piece slides on the pressure blocks through the fixing base after absorbing colored liquid paint in a protection pad; and the colored paint adsorbed on the absorbent cotton piece is transferred onto the pressure blocks.

Description

technical field [0001] The invention relates to the technical field of hydraulic control systems, in particular to a hydraulic control system based on hydraulic pump performance testing. Background technique [0002] The hydraulic pump is the power component of the hydraulic system. It is driven by an engine or an electric motor. It sucks oil from the hydraulic oil tank, forms pressure oil and discharges it, and sends it to the actuator. Hydraulic pumps are divided into gear pumps, plunger pumps, vane pumps and screw pumps according to their structure. Hydraulic pumps are a hydraulic component that provides pressurized liquid for hydraulic transmission. internal combustion engine, etc.) into liquid pressure energy. In high-pressure, high-speed, high-power manufacturing industries, mechanical, electrical, and hydraulic integration equipment accounts for an increasing proportion of the entire mechanical equipment. Hydraulic test benches are used as a It is a necessary equipme...
