Under normal circumstances, the heat transfer medium to the heat conduction oil pump cover and bearing, by the pump cover and the bearing seat surface heat dissipation, so that the temperature of the bearing seat to adapt to the temperature of the shaft sealing performance. Heat conduction oil pump can produce a certain control in the transmission medium, according to a certain technical process to control, to ensure that there is no certain abnormal phenomenon in the actual use, to ensure the use of efficiency. Do not use the gate valve on the input line to adjust the flow to avoid cavitation. Therefore, when choosing the installation position of the conduction oil pump, the heat of the pump cover and the bearing seat should be easy to spread and no heat storage phenomenon occurs. The shell or front and back end cover of the heat conduction oil pump is provided with several corresponding oil inlet and oil outlet, which are connected with the suction pipe and the discharge pipe respectively. Shutdown: Cut off the power supply. The liquid in the conduction oil pump should be emptied, cleaned and the impeller should be rotated 180 degrees regularly to prevent shaft deformation until the oil pump is completely cooled. This heat conduction oil pump can obtain a variety of output displacement, there is another significant advantage: because each suction and discharge port symmetrical layout, and uniform distribution of driven gear, so that the liquid pressure and meshing force balance, thus reducing the load of the pump shaft, bearing, improve the service life of the oil pump. RY series of air-cooled heat pump has a certain pump body structure, can be carried out in accordance with the structure in the actual production assembly, in use shall be carried out in accordance with the working principle of work, RY series of air-cooled heat pump setting of pump shaft on the front end has a stuffing box, sealed performance is reliable, at the same time set in the bearing have mechanical seal device, So a large amount of leakage is not possible and a small amount can be discharged and received through the leak nozzle. Of heat conduction oil pump set, there are two ball bearings in the bearing seat, by conduction of heat conduction oil pump pump impeller side of a ball bearing with the transmission of heat conduction oil lubrication, by coupling side of a ball bearing with high temperature lubricating grease: after running 3000 hours, each ball bearing must be removed after use clean diesel, check whether the contact surface is damaged, if there are any damage, must change the new bearing. Gear adopts three or more than three gears gear heat conduction oil pump, driven gear evenly distributed in the driving gear, can make this kind of gear pump for a variety of displacement, the displacement can be shunt output, to drive different actuators respectively, also can output large displacement of the confluence, fast moving work mechanism.
Note that RY series air-cooled
hot oil pump is running without noise. If normal state is found, it should be dealt with in time. It is normal to have a small amount of leakage at the beginning of operation, and the leakage will be reduced or stopped after a certain period of time when the sealing surface is closed.
RY series air-cooled hot oil pump should not operate continuously under the design flow rate of 30%. If it is necessary to operate under this condition, the bypass pipe should be installed at the outlet, and the flow rate should reach the minimum value above. However, the gear pump oil distribution device is more complex than the conventional two gear type gear pump, especially with internal gear pump gear design, processing is more difficult, these problems remain to be further studied.
