Conductive oil pump routine maintenance (Figure)
1. Heat transfer oil pump is a heat pump circulating fluid, heat exchange equipment is the ideal matching pump. No additional water cooling system at 350 ℃ high temperature, natural cooling, reasonable structure, excellent performance, reliable use, stable operation, saving running costs, and reliable sealing performance, long service life. 2. Thermal oil pump is the latest generation of air-cooled heat pump, which is characterized by no leakage, high temperature, long bearing life. Mainly on the original heat pump bearings to transform the first part of the impeller using imported impeller balance technology on the impeller detection parallelism from the original two bearings to four bearings at the same time the pump shaft proportional to the appropriate bold , In order to improve the stability of the heat transfer oil pump; then the seal of the pump inlet spiral seal, with a return device to ensure that the hot oil pump, heat pump oil seal performance, reliable use. (2) start the motor, when the heat transfer oil pump is operating normally, open the outlet pressure gauge and inlet vacuum pump as it shows the appropriate pressure, gradually open Gate valve, at the same time check the motor load and pressure fluctuations. (3) If it is found that there is an abnormal sound and vibration of the heat transfer oil pump, it should stop immediately to check the reasons. (4) During the operation of the heat transfer oil pump, the bearing temperature can not exceed the current ambient temperature of 35 ° C and the maximum temperature can not exceed 80 ° C. Control the flow and lift of the heat transfer oil pump in the range indicated on the label to ensure that the heat transfer oil pump in the highest efficiency point of operation, in order to get the maximum energy saving effect. (6) Regular inspection of heat-conducting oil pump bearings and seal wear, wear larger (7) When the heat-conducting oil pump is used in the winter season, after stopping the vehicle, unscrew the oil-drain plug in the lower part of the pump to release the medium to prevent the oil from containing the moisture in the heat-conducting oil to freeze the pump. (8) Thermal Conductivity Long-term deactivation of the oil pump, the pump required to open all, dry the water, the rotating parts and joints coated with grease installed, properly protected. (9) heat pump oil pump shaft at the front with a stuffing box, the sealing performance is more reliable, At the same time in the bearing seat is provided with a mechanical seal, so a lot of leakage can not occur, and a small amount of leakage can leak through the leakage nozzle to receive. (10) heat pump every time before the pump filled with liquid, so that Self-priming capability to strengthen and prolong life. (11) regular observation of the entire heat-conducting oil pump parts are not loose situation.
