The working fluid of the hydraulic coupler (working medium) is the medium that the coupler transmits torque.

For the same type of coupler, the amount of liquid filling directly affects the transfer torque of the coupler.

The basic rule is that the more liquid is filled in the specified range, the greater the transmission torque of the coupling.

When the transfer torque is constant, the more liquid is filled, the higher the efficiency is. However, when the starting torque increases, the overload coefficient also increases.

The coupling device of the same specification can be matched with several motors of different power to meet the requirements of different working machines.

Hydraulic coupling amount (liquid volume range), with specifications of hydraulic coupling has its certain scope of transfer torque (power), we call it the power, the power band and coupling charging range corresponding to the.

Scope of liquid coupling 40 to 80% of the total volume, not allowed beyond this range, more do not allow full, because the amount of liquid is 80% above volume, coupling turns, rose sharply due to overload booster, working fluid volume expansion, accidentally, the sealing, cause leakage, even coupling shell cracking, mechanical damage.

However, if the filling amount is less than 40% of the volume, the bearing may not be lubricated enough, and the coupler is not fully utilized, and the volume is large, which makes no sense. It is suggested to choose a smaller size model.


Hydraulic coupler usually USES oil medium.

The working fluid is recommended to use no. 32 turbine oil, no. 6 hydraulic transmission oil, no. 8 hydraulic transmission oil.

The moment limiting coupler used in underground coal mine USES water and refractory liquid as medium.

Screw the feeding liquid plug, filter the working fluid with 80-100 mesh filter screen, inject the amount into the coupling device, and tighten the injection fluid plug for test run.

No strict requirements, the user can rotate coupling shell, when the mouth filling spin to about 55, from vertical centerline high lumen working liquid flow can be just as coupling can deliver better oil level of high power rating.

The user is recommended to adjust the amount of oil filling according to the actual working load and operating conditions.
