How to use and maintain the torque limited hydraulic coupler?
Do you know what to pay attention to when using the limited torque hydraulic coupling at the beginning? How to operate correctly when using? What do you need to pay attention to?
There is no sharp and frequent positive inversion. Speaking from the coupling theory is reversible, but positive sharp, but positive sharply, due to inertia force is too large and damage the connecting parts coupling, so as to strictly abide by the rules, avoid reversing sharp frequently, especially the use of coupling in the tower crane and bridge crane as host to pay attention to this point.
The output shaft of the coupler is turned to the same direction as the motor shaft, and the motor turn should be checked for the first time.
When the motor reaches the rated speed, from the motive must start the transfer, if the motive does not move, must stop immediately, check whether the load is too large and brake phenomenon.
During continuous operation, the working temperature of the coupler shall not exceed 90 degrees, and the working temperature of the water medium shall not exceed 100 degrees.
The quality of the working oil should be checked regularly (every 3000 hours). If the oil is found to be bad, it should be replaced immediately.
Check the position accuracy of motor shaft and working shaft regularly and rectify it at any time.
Regular inspection of motor and working machine mounting foundation to avoid early damage caused by vibration and coupling due to poor foundation rigidity.
Regularly check the elastic coupling of elastic block or elastic plate wear, and regular replacement.
It is not allowed to disassemble the coupler housing at random, so as to avoid sealing and assembly accuracy and balance accuracy, resulting in accidents.
The coupling oil medium is not allowed to be changed into water medium.
It is not allowed to flush at random, and is not allowed to be filled. The liquid should be strictly pressed according to the instruction.
In the coupling with bearing cavity, the grease has been filled in the bearing cavity at the factory (commonly known as glycerin). When the coupler is running, the grease is diluted and leaked due to the heating of the bearing, which is not the leakage of the working medium of the coupler, so the difference should be noticed.
In order to facilitate the cooling of the self cooling hydraulic coupling, the hydraulic coupling should be placed in a well ventilated place to help cooling.
To prevent accidents, the coupler shall be equipped with a reliable shield.
