Heat transfer oil pump transmission medium and operation

Heat pump has a certain pump structure, in the actual production according to the structure of the form of assembly, in use in accordance with the working principle of work, the heat pump shaft pump at the front with a stuffing box, the sealing performance is more reliable, at the same time in the bearing A mechanical seal is provided so that a large amount of leakage can not occur and a small amount of leakage can be discharged through the leak nozzle. It is normal to have a small amount of leakage early in operation, and the leakage will decrease or stop after the sealing surface has run through a certain period of time. There are two ball bearings in the bearing housing of the heat transfer oil pump. One ball bearing on the pump impeller side of the heat pump is lubricated by the heat transfer oil. One ball bearing on the coupling side is lubricated with high temperature grease. After a ball bearing is operated for 3000 hours, it must be dismantled and cleaned with diesel oil. Check if the contact surface is damaged. If it is damaged, it must be replaced with a new one. Do not use the input pipe gate valve to regulate the flow, to avoid cavitation. Conductive oil pump should not be less than 30% of the design flow continuous operation, if you must operate under the conditions, it should be installed in the bypass bypass pipe exports, and to flow above the minimum. Multi-gear with three or more than three gears constitute a multi-gear gear pump, driven gear evenly distributed around the driving gear, allowing such gear pump to obtain a variety of displacement, the displacement can either split output , Respectively, to drive different actuators, but also can confluence output large displacement, to achieve the rapid movement of the work organization. The housing of the heat-conducting oil pump or the front and back end caps are provided with corresponding inlet ports and outlet ports respectively, and are respectively connected with the oil suction pipe and the oil discharge pipe. This heat transfer oil pump in addition to access to a variety of output displacement, another significant advantage is that: due to the suction and discharge ports symmetrically arranged, and the driven gear evenly distributed, so that the hydraulic pressure and meshing force to balance, thereby reducing The pump shaft, bearing load, improved gear pump life. However, the oil pump of the gear pump is more complicated than the conventional two-gear gear pump. In particular, it is difficult to design and process the internal gear of the gear pump with internal gear. These problems are still to be further studied. Often check the loose bolts of the situation, the heat pump casing temperature and inlet temperature are the same, the export pressure gauge fluctuations and pump vibration. Note that there is no noise in the operation of the heat transfer oil pump, such as the pilot state should be promptly found. Shutdown: cut off the power. The liquid in the hot oil pump will be drained, cleaned, and the impeller should be rotated 180 degrees periodically to prevent the shaft from deforming until the pump is completely cooled. Transmission medium to heat pump oil pump cover and bearing the heat from the pump cover and bearing surface cooling, so that the bearing temperature to adapt to the shaft sealing performance temperature. Therefore, the choice of guided heat pump installation location, to make the pump cover and bearing seat of the heat to facilitate diffusion, does not appear any heat storage. Heat transfer oil pump can produce certain control in the transmission medium, according to a certain technical process control, to ensure that in actual use there is no certain anomalies, to ensure the use of the use of efficiency.
