What should be noted when operating and starting the hydraulic system in the hydraulic station?

　　Many details in the operation and startup process of hydraulic systems at hydraulic stations are easily overlooked, often leading to failures. Next, Shuangzhuo Hydraulic Systems manufacturer will share what key details operators should pay attention to during the running and startup of hydraulic station systems.

　　1. The hydraulic oil in the tank should always be kept at the proper level.

　　When the pipelines and cylinders have large capacities, sufficient oil should be added first. After starting up, as oil flows into the pipelines and cylinders, the oil level will drop—potentially even exposing the filter above the oil surface—so it’s essential to top up the oil again promptly. Additionally, leaks may occur during operation, so a liquid-level gauge should be installed on the tank for regular monitoring and easy refilling of oil.

　　2. Precautions when using outdoor hydraulic equipment.

　　As outdoor temperatures fluctuate significantly with the seasons, it's best to use oils with a high viscosity index whenever possible.

　　② Due to temperature fluctuations, water vapor in the hydraulic system’s oil tank may condense into water droplets. Check weekly during winter and remove any condensation immediately upon detection.

　　③ Outdoors, oil should be changed frequently because dirt easily gets into it.

　　3. Precautions for the first-time startup of the oil pump.

　　① Fill the pump with oil.

　　② Check whether the rotation direction is correct.

　　③ Are the inlet and outlet connected in reverse?

　　④ Test by turning it with your hand.

　　⑤ Check for air leaks on the suction side.

　　⑥ Start and operate within the specified speed range.

　　4. Precautions for starting the oil pump in low-temperature conditions.

　　① When starting the oil pump in cold regions or during winter, first turn it off and repeat this process several times to raise the oil temperature. Once the oil pressure system operates smoothly, you can proceed with normal operation.

　　② It’s best to heat the fuel tank with a heater for a short period to raise the oil temperature. However, at this point, components like the pump remain cold—only the oil is hot—which can easily lead to malfunctions. Be sure to take this into account.

　　5. Other.

　　① The relief valve should be unloaded when the oil pump is started or stopped.

　　② The set pressure of the relief valve must not exceed the maximum pressure of the hydraulic system.

　　③ Always strive to maintain a stable voltage for the solenoid valve, as fluctuations could lead to coil overheating.

　　④ Wear-and-tear parts, such as seals, should always have spare replacements available for timely replacement.
