The basic principle of the torque type hydraulic coupler
The torque type hydraulic coupler (hydraulic coupler, hydraulic coupling) is a widely used hydraulic transmission element.
Engine, motor, diesel engine drive coupling pump wheel spin, pump impeller blade working liquid, stirring cavity under the centrifugal effect, (do circular motion and flow) pump wheel to turn mechanical energy into liquid can be passed to the turbine blades, turbine work will absorb liquid can be passed to the machine again.
The driving medium of the power machine and the working machine is liquid, so its advantage is incomparable with other power connection equipment.
Basic functions of hydraulic coupler:
With flexible drive, slow shocks, isolation function of torsional vibration, can prolong the startup time, reduce the starting current, make the engine start light load, heavy large inertia load starts difficult problems, overload protection prime mover.
And this product can reduce the motor seat number to achieve energy saving effect.
When ordering, please indicate the power and speed of the original motor, the original motive and the shaft diameter of the working machine, the key height, the key width and so on.
Other forms should indicate the diameter of the pulley, the groove, the number of slots, the diameter of the diameter of the brake wheel, and the coupling of the vertical installation should be marked as vertical or vertical.
With the original motive, the shaft hole tolerance recommended by the working machine is recommended to adopt the G7 tolerance, if not special mark will be processed according to the benchmark hole.
Please read the instruction manual carefully before installation and debugging, but there is an unknown place to consult the professional to give guidance.
When installing, it should strictly guarantee the coaxial degree of input and output shaft hole, the installation of hydraulic coupler has special installation and disassembly tool, if necessary, can be ordered.
Hydraulic couplings generally use oil media.
Working fluid recommended: no.32 turbine oil, no.6 hydraulic transmission oil, no.8 hydraulic transmission oil.
Water and refractory liquid are used in underground coal mine.
The maximum amount of liquid filled in the torque type hydraulic coupler shall not exceed 80% of the total volume.
(generally about charging Angle 45 °, watch around 10 o 'clock).
Fusible plug type is limited moment coupling overheating protection device (generally is 125 °, 140 °, special 160 °) absolutely not substitute other plug for use.
Fusible plug can effectively protect the overheating, but working medium jet can cause pollution and inconvenience, user's special requirements, the two do not spray liquid temperature control switch can be used (non-contact wireless acousto-optic alarm device, shifter lever to promote travel switch device).
The explosive plug is mainly used for the moment coupler of water medium and difficult combustible medium.
The output steering of the coupling is consistent with the power machine, and the power machine is reversible, but it should avoid the sharp and negative transformation direction.
Periodically check the quality of the working medium of the coupler and the damage of the elastic block, and replace it in time.
Non - professional personnel are not allowed to uninstall the coupling, so as to avoid sealing and balance accuracy.
