What are the principles for the selection and matching of a hydraulic coupler?
1. meet the principle of working machine transmission requirements
2. the hydraulic coupling should be selected according to the driving requirements of the working machine. If the working machine needs to solve the problem of starting difficulty and overload protection, we must choose the torque limiting hydraulic coupler. If we need to speed up the energy saving, we must choose the speed regulating hydraulic coupler. The moment coefficient of the pump theory takes into account that the torque coefficient of the pump wheel of the hydraulic coupler is related to the ratio of the speed. The speed ratio is large, the efficiency is high, the torque coefficient of the pump wheel is small; on the contrary, the speed ratio is small, the efficiency is low, and the torque coefficient of the pump is large. Therefore, when selecting matching, the torque coefficient of the pump wheel and the speed ratio (i.e. efficiency) must be taken into account, and the efficiency is high and the torque coefficient of the pump wheel is also large.
3. principle of high efficiency and energy saving
For constant torque machines, the torque limiting fluid couplings should be chosen. It is not particularly necessary not to choose speed regulating hydraulic couplings, because the larger the speed range is, the lower the efficiency. For linear or sectional load lines, the variable speed hydraulic coupler is recommended for working machines with variable load. It can save energy by using speed regulation, but also does not permit long-term operation at the maximum heating point, because this will waste resources.
4. the principle of safety and reliability:
The motor and working machine can be protected from damage when starting and overloading. For the moment limited hydraulic coupling, the overload protection coefficient should be lower than the overload coefficient of the motor, and there is a super - temperature and overloaded protection device. The speed regulation type and the moment limit hydraulic coupling used in coal mine should have the function of explosion proof.
5. principle of mobile operation
Must be able to ensure the whole system working in specified stable operating points, not speed up, do not turn, smooth operation, no fluctuation, speed sensitive and reliable.
6 the principle of convenient and reliable connection with the motor, the working machine (including the reducer, the increasing speed device)
Connect the hydraulic coupler and power machine and working machine must be safe and reliable, convenient installation and disassembly, short axial size and speed of large size yox must use the connection without moving the working machine and power machine can be disassembled, and must ensure safe and reliable connection.
In addition, the hydraulic coupler used in wet, dust, cold, hot, flammable and explosive conditions must have the function to adapt to the bad working environment.
