Test stand - Pressure aggregate
Test stand for pressure tests of hydraulic control blocks and linear hydraulic motors
The mobile pressure stand for the pressure tests of the safety blocks is a compact unit consisting of a off-drop bath which is fitted with wheels. On the drain pan is an aluminum tank for oil and a removable frame with a work surface . There is an electric motor with hydrogenerator holder and clutch, thermostat and level sensor on the lid of tank.
The hydrogenerator is toothed, tandem. There is a check valve at the outlet of each pump.
- The pressure from the first hydrogenerator flows into a two-position block, which is fitted with two distributor and built-in sealed safety valves. One switchgear serves to pressurize a hydraulic block located on the working surface and the other serves to pressure hydraulic linear motors. Output pressure control from the block is possible with a safety valve in increments of ten bars.
- A single-block is connected to the second hydrogenerator. It is fitted with a switchgear and a sealed safety valve. The switchboard is designed to pressure the hydraulic block located on the work surface. Output pressure control from the block is possible with a safety valve in the range of 10-100 bar. The waste filter is located on the tank lid. The waste filter is equipped with a filter insert clogging indicator.
The compartment of the pressure station, where the pressure tests of the lock blocks are carried out, is provided with a polycarbonate cover. The hydraulic aggregate can only be started when the polycarbonate cover is closed. The closed position of this cover is guarded by the limit switch.
