XNUMX. Classification of vertical hydraulic couplings


According to the liquid filling method, the vertical coupling can be divided into ordinary type, torque-limiting vertical hydraulic coupling and speed regulating vertical hydraulic coupling; according to the transmission type, the vertical hydraulic coupling can be divided into There are two types of direct drive and parallel drive; according to the installation position of the coupling and the power machine, the vertical hydraulic coupling can be divided into two types: sitting and hanging.


1. Sit and stand.The coupling sits above the motor.


2. Hanging up.The coupling hangs below the motor.


The speed regulating hydraulic coupling is limited by the structure, only the hanging type is not the sitting type, that is, the motor is above the coupling, and the working machine is below the coupling.


Second, the structural characteristics of vertical hydraulic coupling


Torque-limiting hydraulic coupling equipment supplier: On the surface, it seems that the vertical hydraulic coupling is the horizontal hydraulic coupling used upright, but it is not the case. The vertical hydraulic coupling has the following characteristics:


1. The seal at the lower end of the coupler needs to be strengthened.When the horizontal coupler is working, most of the working liquid works at the outer diameter of the circulation circle, so the possibility of leakage at the center of the main shaft is small.The vertical coupler is installed vertically, and the working fluid is likely to leak downward due to gravity.In order to prevent leakage, a reliable sealing structure must be adopted, and some cases are equipped with a cover at the lower end.


2. The auxiliary cavity should be located below


3. Before the coupler is started, the auxiliary chamber below is filled with working liquid, which reduces the oil filling rate of the working chamber, reduces the starting torque, and makes the starting smooth and soft.On the contrary, if the auxiliary chamber is set at the top, when the coupler starts, 99% of the working chamber is filled with oil, which increases the starting torque and starting shock, which is not conducive to the smooth start of the working machine.


4. When overloaded, the working fluid moves in a large circulation, relying on dynamic pressure and gravity, it can quickly leak into the auxiliary cavity below, and timely protect the motor and working machine from damage when overloaded.If the auxiliary chamber is above, the direction of liquid flow is opposite to the direction of the auxiliary chamber when overloaded. It needs to rely on static pressure and overcome gravity to push the liquid to the upper auxiliary chamber, so the speed of its leakage is slow, which is not as good as the coupling of the auxiliary chamber below. The device is sensitive.


5. Oil filling plugs and fusible plugs should be located above.To facilitate filling and removal of fusible plugs, the filling plug and fusible plug should be located above.At the same time, an oil drain plug should also be provided below, so that it can be used when changing the oil.Usually the position of the vertical coupler filling port is exactly the position of 80% oil filling.
