The preparations for the hydraulic system before commissioning have been described in detail above. In this paper, Dalan Hydraulics will explain the hydraulic system in the commissioning phase.
1. No-load debugging: first run at low speed for 10~20min, sometimes it is necessary to remove the connection between hydraulic cylinder or hydraulic motor and load. Especially in the cold season, this kind of non-load low-speed operation (warm-up operation) is especially important. Some imported equipments often have strict requirements, and some are equipped with heaters to heat the tank oil.
Trial operation of work that can be operated at low speed and low pressure;
2, jog: first jog the pump, observe whether the hydraulic pump steering is correct, the power supply reversed not only no oil output, and sometimes accidents, so you should not "click" when the operation starts.
3. When the pump sound is normal and the oil is continuously output and no other abnormal phenomena occur, it can be put into continuous operation and no-load debugging;
4. Gradually and evenly boost the acceleration. The specific operation method is to repeatedly tighten and immediately select the pressure or flow adjustment handle of the overflow valve and flow valve several times, and observe the pressure rise and fall of the pressure and the speed change of the actuator with the pressure gauge. Situation, the heat pump, vibration and noise of the hydraulic pump, and found that the problem is analyzed and solved;
5. According to the action cycle table, combine the electrical machinery to debug each single action first, then switch to the cycle action debugging to check whether the actions are coordinated. There are some problems in the debugging process, such as crawling, impact and non-commutation. Especially for complex domestic and imported equipment, if there are big problems, we can consult with you and resort to hydraulic equipment if necessary. factory;
6. Finally, enter the full load debugging, that is, according to the technical performance of the hydraulic equipment, the maximum working pressure and the maximum (small) working speed test, check the power, heat, noise vibration, high-speed impact, low-speed crawling, etc., check the leakage of each part. In the case of oil, oil pressure is often leaked when the pressure is not high, and the problem is eliminated in time, and this is recorded in writing;
7. Under normal work, the test piece can be tested. After the test is completed, the machine tool should be restored after parking, and the detailed debugging records should be archived. Some imported equipment commissioning records can be used as a basis for claims;
8. The hydraulic equipment adjusted by the above method, the handles are generally not to be moved any more. For the equipment to be packaged, the handwheels should be completely loosened. For long-term unused equipment, the handwheel of the pressure valve should be loosened to prevent it. The spring is permanently deformed and affects the mechanical equipment. "target=_blank>There are various fault conditions when the mechanical device is activated, which ultimately affects the performance.
