Analysis on the Commissioning Process of Hydraulic Pump Station

The speed commissioning details of the hydraulic pump station system shall be carried out one by one loop. When commissioning one loop, it is necessary to close other loops. The whole hydraulic system can be put into use only when it starts, reverses and stops according to the set speed. Next, Xuzhan Mechanical Department will talk to us about the commissioning process of the hydraulic pump station.

The pressure test of the hydraulic pump station system shall be conducted after the commissioning of the device is completed, and the device shall be left behind after passing the inspection.

1. The test pressure shall conform to the following rules in general environment.

1、 The test pressure shall conform to the rules: 1.5P when it is less than 16MPa; 1.25P at 16~31.5MPa; 1.15P when it is greater than 31.5MPa.

2、 In the circuit with large impact or severe pressure change, the test pressure shall be greater than the peak pressure.

2. Before the system is filled with liquid, its cleanliness shall conform to the rules. The standards, types and characteristics of the filled hydraulic oil (fluid) shall conform to the rules of the introduction book; During liquid filling, the air outlet shall be opened repeatedly to clean the air (when oil sprays out of the exhaust valve, it can be seen that the air is clean), and the throttle valve shall be opened at the same time.

3. The hydraulic cylinder, hydraulic motor, servo valve, pressure relay, pressure sensor and accumulator in the system shall not be included in the pressure test.

4. The test pressure shall be increased step by step. The pressure should be stabilized for 2~3min for each increase. After reaching the test pressure, hold the pressure for 10min, and then reduce it to the working pressure. The inspection shall be carried out to ensure that all welds, joints and seals of the system are free of oil leakage, and the pipeline is free of long-term deformation.

5. In case of unusual movements in the system, the test shall be stopped in time. It is necessary to relieve the pressure before handling the fault. If there are welds that need to be re welded, it is necessary to remove the pipe and remove the oil before welding.

6. During the pressure test, the pipe shall not be hammered, and no open fire homework or heavy noise homework shall be held within the 5m limit of the test area.

Mediation and commissioning

The commissioning of the hydraulic pump station system shall be left behind before the relevant civil engineering, machinery, electrical, appearance, safety protection and other projects are recognized as having test run. Generally, system commissioning shall be carried out according to the sequence of pump station commissioning, system pressure commissioning and speed commissioning of performance components. The pump station commissioning shall be left behind after two hours of working pressure. The system temperature is appropriate, and the working process is free of abnormal noise and vibration. The details of system speed commissioning shall be carried out one by one. When commissioning one circuit, it is necessary to close other circuits. The whole hydraulic system is starting and reversing, The machine can be put into use only when it works stably at the set speed during the rest.
