With the continuous improvement of heat-conducting oil pump technology, RY-type heat-conducting oil pump coupling produced by our company is also being improved. The heat-conducting oil pump coupling is divided into heat-conducting oil pump belt coupling, heat conducting oil pump three jaw flexible coupling, stainless steel membrane Chip coupling, pin coupling and so on. First, the thermal oil pump belt coupling is the common use of thermal oil pump coupling. The advantage is that the coupling of the motor and the coupling of the heat-conducting oil pump are connected through soft preserved eggs, the concentricity of the pump is not very strict, and the temperature of the heat-conducting oil pump is not transmitted to the motor through the coupling. Qi shortcomings are: belt coupling installation, assembly trouble. Second, the thermal oil pump coupling is the first three-jaw type flexible coupling, the advantage is the installation of flexible coupling, assembly more convenient; disadvantage is easy to damage the elastic block, the installation is the heat pump and motor concentricity requirements teach high . Third, the stainless steel diaphragm coupling is mainly used for large flow heat pump, Qi is not to deliberately adjust the pump concentricity, diaphragm coupling and gear coupling, there is no relative sliding, no lubrication, sealing , No noise, no maintenance, easy to manufacture, can partially replace the gear coupling. The disadvantage is: the price is much higher than the other couplings. Fourth, thermal oil pump pin coupling is characterized by simple structure, easy installation, easy replacement, small size, light weight, which has been widely used, if the installation and adjustment to maintain the relative displacement of the two axes within the specified range, then Couplings will have satisfactory performance and long working life. Therefore, it can be widely used in various medium and small power transmission shafts driven by motors, such as reducer, crane, compressor, conveyor, textile machine, winch, ball mill and so on. The disadvantage is: installation is too much trouble.
