Hydraulic coupling maintenance and inspection regularly, check oil level and replenish gas, a new machine for the first time after 500 hours operation should be removed for cleaning oil filter oil suction pipe, shutdown for maintenance work with cleaning machine, oil pump and oil filter regularly, to regularly check the oil, the timely replacement of oil for the qualified work; oil tank emptying coupling, screw the box under the input and output ends of the lower part of the oil drain hole plug wire, or cut-off valve in the oil drain hole loading.

If the coupler has the quality problem, it can be divided into two types, one is the leakage of oil leakage and the two is the bearing damage of the coupler.

There are several reasons for bearing damage, one is that the quality of bearing is not qualified. The two is that the balance of the coupler is not well balanced, and the vibration is caused, and the three is the poor basic strength of the site installation. The four is that the coaxiality of the installation is not good. In order to solve the above problems, the coupler can even exceed the quality of the original imported products. The following treatment can be done: one is the seal problem, and the import seal is adopted. Two is the bearing problem, the use of imported bearings. The three is the balance treatment of the coupling of the coupler.

The transmission efficiency of a hydraulic coupler is equal to the output shaft speed multiplied by the output torque (output power) and the input shaft speed multiplied by the input torque (input power) ratio. The output torque is equal to the input torque and the friction torque, so its output torque is always less than the input torque. The input shaft of the hydraulic coupler and the output shaft are connected by the liquid, and there is no rigid connection between the working members. Higher efficiency can be obtained when the speed ratio of normal hydraulic coupling in normal operating conditions is more than 0.95. The characteristics of the pike filter core of a hydraulic coupler vary from the shape of the working chamber to the pump wheel and the turbine. If the oil of the hydraulic coupling is empty, the coupling is in the disconnect state and can play the role of the clutch. After the pump wheel and the turbine are fitted, the annular cavity is formed, and it is filled with working oil. The pump wheel is usually driven by an internal combustion engine or motor to drive the fluid to make a more complex centripetal force.
