How to maintain hydraulic flap gates

The hydraulic flap gate manufacturer stated that when selecting and matching hydraulic flap gates, it is important to check whether the actual on-site requirements match the parameters. The rated load is particularly important, that is, the closing force, holding force, and opening force should all match the actual requirements

It is also necessary to check whether the piston and oil cylinder meet the requirements, especially whether their sealing can withstand high pressure and tear strength is sufficient. Attention should also be paid to aging conditions, friction, and adhesion. It is also necessary to confirm that each electrical component has a product certificate of conformity and no damage has occurred

Before operating the hydraulic replica gate, it is necessary to clean the oil cylinder, gate groove and other operating areas to avoid external obstacles to the gate and oil cylinder during operation; It is also necessary to clean and replace the oil filter core of the hydraulic system in a timely manner; The temperature of the environment should not be lower than the temperature of the design working condition. Before flushing, the air should be expelled. After the oil is filled, the overflow valve of the oil pump should be adjusted to ensure that the oil pump runs at 50%, 75%, and 100% for 5 minutes. During this 5 minute period, check for any noise, vibration, high oil temperature, or pipeline oil leakage
