First of all, after the heat-conducting oil pump and the pipe are installed, whether it be the use of water pressure, air pressure, heat pump inlet and outlet valve must be closed before pressure test to prevent damage to seals, resulting in oil spills. Heat-conducting oil pump in use has good precautions, according to certain standards and forms of good use, to ensure the use of good life and value. 1. Thermal oil pump boot preparation (1) clean up the site, unscrew the bearing screws, add thermal oil as lubricant. (2) Check whether the direction of motor rotation and heat transfer oil pump rotation, the boot should check the foundation and the bolt is loose, the seal is normal. (3) hand-moving coupling pump should be flexible rotation. (4) should be used before the boot of the thermal conductivity of oil will be filled with thermal oil pump to get rid of heat transfer oil pump air, this time spit outlet pipe gate valve should be closed. (5) The heat-conducting oil delivered should be uniformly heated before driving, and the preheating is carried out continuously by using the heat-conducting oil being conveyed. Preheat standard: heat pump oil pump casing temperature not lower than the inlet oil temperature 40 ℃, preheat speed of 50 ℃ /, warm-up when the pump should be on the side legs nuts loose 0.3-0.5 mm, preheated Should be tightened. 2. Thermal oil pump boot (1) a comprehensive inspection of the preparation is perfect. (2) Open all kinds of instrument switch, start the process, always pay attention to motive power readings and vibration, the vibration value does not exceed 0.6 mm, if the abnormal shutdown should be checked. (3) Turn on the power, when the heat transfer oil pump reaches the positive speed, and the instrument shows a considerable pressure, gradually open the gate valve on the output pipe and adjust to the need conditions. In the case of a closed gate valve on the output line, the pump must not work continuously for more than 3 minutes. (4) During the initial operation of the heat-conducting oil pump, the equipment in the production process is gradually heated to 100-130 ° C., and kept running at this temperature. The dewatered air is completely evaporated into the oil in the heat-conducting oil, and the equipment is heated To the operating temperature. (5) Turn off the heat transfer oil pump after the equipment is heated to the operating temperature for 3-4 hours, check the concentricity of the heat transfer oil pump shaft and the motor coupling. The deviation of the pump shaft and the motor shaft should be controlled within the allowable range Within the pump shaft rotation hand should be lightweight and flexible rotation, if not meet the above requirements, should be re-adjusted. Conductive oil pump before and during use to do a good job of inspection and preparation, in accordance with certain principles and methods of use, to ensure good performance and value, can play in the use of good performance.
