Problems solved by technology

Since the detection of hydraulic equipment is generally measured under no-load conditions, it is impossible to simulate the synchronous jacking condition under loading conditions, resulting in inaccurate measurement synchronization accuracy
In addition, because the hydraulic equipment is detected manually by some simple testing instruments (such as calipers), not only the detection efficiency is low, but also the measurement data will produce large errors, which will greatly affect the synchronization of the synchronous jacking device. precision

Description

technical field [0001] The invention relates to a test device for synchronous jacking hydraulic equipment, in particular to a loading test bench for a synchronous jacking device. Background technique [0002] Current synchronous jacking hydraulic equipment (such as hydraulic pumps) all need to measure the pressure and synchronization accuracy of the equipment before leaving the factory to check whether the hydraulic equipment meets the synchronization accuracy requirements. First, the synchronous jacking hydraulic equipment pushes out the jack pin when it is empty, and then uses a caliper to measure the lifting height of the jack pin, and then calculates the synchronous accuracy of the synchronous jacking hydraulic equipment. Since the detection of hydraulic equipment is generally measured under no-load conditions, it is impossible to simulate the synchronous jacking condition under loading conditions, resulting in inaccurate measurement synchronization accuracy. In additio...
