What Are The Advantages Of Using Hydraulic Couplings To Drive Fixed Belt Conveyors?

 1. it can improve the service life of the equipment. Because the working medium of the hydraulic coupling is liquid, the input shaft and the output shaft are not rigidly connected, so the shock and vibration caused by the sudden accumulation or accumulation of external load can be transformed into a continuous gradual change so that the dynamic load can be eliminated or partially eliminated. Thus prolonging the service life of transmission parts.

2. A smooth start saves electric energy. The hydraulic coupling drive, no matter how big the load is driven, is equivalent to a light load starting for the motor. And the electric function in a very short time to start up, and the load is gradually increased, so as to achieve a smooth start, save the purpose of electricity.

3. It can improve the starting torque. Generally, the starting torque of the squirrel cage motor is relatively low. After using the hydraulic coupling, it can make full use of the overturned torque of the motor. The starting torque value can reach about 95% of the overturned torque of the motor, which completely improves the starting characteristics of the motor.

4. Overload protection. Because the maximum torque value of the hydraulic coupling is lower than that of the motor, it can protect the motor from overload. Once the oil temperature is too high due to a long time overload operation, the overheat protection plug on the shell melts, the working liquid spouts and the hydraulic coupling stops working, thus protecting the motor and other transmission parts.

5. It can make a load of each motor evenly distributed in multiple motor transmissions.

Will the hydraulic coupling spray oil and catch fire? How to prevent it?

Fixed Belt conveyor hydraulic coupler used in our country at present most of the working liquid for the oil, when the hydraulic coupling fusible alloy, conveyor overload (roller turn belt running deviation, the overload or other reasons), the hydraulic coupling oil temperature is higher, when the oil temperature over 180 degrees of turbine oil flashpoint, will damage the rubber seals, and high-temperature oil, air, and burning.

The method to prevent oil injection fire of hydraulic coupling is as follows:

1. Use qualified fusible plugs according to the provisions.

2. Modify the hydraulic coupling, and use non-combustible liquid or water as the working liquid.

Those matters should be paid attention to when filling hydraulic coupling oil

Note when oil filling:

1. Oil must go through 80 ~ 100 mesh /cm2 filter before it can be injected into the coupling.

2. Only 80% of the total volume of the coupling can be injected, not too much. It is not allowed to be full, otherwise, the oil temperature will be too high in operation and the coupling will be damaged.

3. The minimum amount of oil injection shall not be less than 40% of the total volume of the coupling, otherwise, the bearing will not be sufficiently lubricated and prematurely damaged.

4. According to the coupling power transfer and oil injection curve, with the gauge accurately injected a specified amount of oil. Inject the specified amount of oil or, slowly turn the coupling until the oil begins to overflow from the oil injection hole, the oil injection hole position from the floor (or another reference) height, horizontal from the motor or guard marked for daily maintenance check oil level reference point.
