The correct use of thermal oil pump First thermal oil pump and pipe installed, whether it is using water pressure, pressure, heat pump import and export valves must be closed before the pressure test to prevent damage to seals, resulting in oil spills. 1, boot preparation (1) clean up the site, unscrew the bearing screws, add thermal oil as lubricant. (2) hand-moving coupling pump should be flexible rotation. (3) should be used before booting the thermal conductivity of oil will be filled with thermal oil pump to get rid of heat transfer oil pump air, then spit out the pipe valve on the gate should be closed. (4) the heat transfer oil delivered before driving uniform heating, preheating is the use of the heat transfer oil is continuously through the pump body. 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, boot (1) a comprehensive inspection of the preparation is perfect. (2) Turn on the power, when the heat transfer oil pump reaches 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. (3) After the initial operation for 3-4 hours, turn off the heat transfer oil pump after heating the equipment to the operating temperature, check the concentricity of the heat transfer oil pump shaft and the motor coupling, and 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. (4) During startup, always pay attention to the motive power readings and vibration conditions, the vibration value does not exceed 0.6 mm, if the abnormal shutdown should be checked.
