 Capable of supporting vertical mounted vertically with vertical mechanical fluid coupling known as the vertical hydraulic coupling. Their classification with the following features:

A vertical hydraulic coupling classificationhydraulic hose

By fluid-filled way, the vertical coupling can be divided into common type, constant filling vertical hydraulic coupling and variable speed vertical hydraulic coupling; divided by type of drive, the vertical hydraulic coupling can be divided into directly connected both transmission and parallel transmission; coupling and power machine installation location points, the vertical fluid couplings can be divided into sitting and hanging stand two.

(1) sitting. The coupling is sitting above the motor.

(2) hanging legislation. The coupling is hanging below the motor.hydraulic manifold block

    Variable speed hydraulic coupling by structural constraints, only hanging Vertical did not sit Vertical, motor coupling above the working machine below the coupling.

B vertical structural characteristics of the fluid coupling

     On the surface, it seems that the vertical hydraulic coupling is used horizontal hydraulic coupling stand up, it is not true, vertical hydraulic coupling has the following characteristics:

(1) coupling down one end of the seal should be strengthened. The horizontal coupling at work, most of the working fluid to work in a loop round at the outer diameter, so the possibility of leakage of the spindle center portion. Vertical coupling mounted vertically, by gravity, down the possibility of leakage of the working fluid. To prevent leaks, must be reliable seal structure, some down one end plus casing.

(2) auxiliary chamber belowhydraulic couplings

1) before the coupling is not started, in the bottom of the auxiliary cavity is filled with the working fluid, and thus reduces the rate of the oil-filled working chamber, so that the starting torque is reduced , the start becomes smooth and soft. Conversely, if the auxiliary chamber is located at the start of the above coupling, the working chamber 100% oil-filled, so that the starting torque and increase the impact and start work machine is not conducive to a smooth start.

2) working fluid overload circulation movement, rely on dynamic pressure and gravity quickly leaked into the bottom of the auxiliary chamber, in a timely manner to protect the motor and work machine from damage when overloaded. If the auxiliary chamber at the top, overloading the liquid flow direction of movement opposite to the direction of the auxiliary chamber, the need to rely on the static pressure to overcome gravity and push the liquid to the top of the auxiliary chamber, and thus the discharge of slow, not as good as the auxiliary chamber below the coupling is sensitive.

3) should be located in the top of the fill plug and fusible plug. Should be set up for the convenience of refue ling and demolition fusible plugs, fuel plug and fusible plug at the top. Below should also be set to put the oil drain plug for oil change. Usually the refueling position of the mouth of vertical coupling is exactly the location of the 80% oil-filled.
