The correct use of hot oil pump: First, hot oil pump and pipe installed, whether it is using water pressure, pressure, hot oil pump inlet and outlet valves must be closed before the pressure test to prevent damage to seals, resulting in oil spills. â… . Boot preparation One, clean up the site, unscrew the bearing screws, add hot oil for lubrication. Second, hand-moving coupling pump should be flexible .Third, boot before use should be transported hot oil filled hot oil pump , In order to get rid of the heat in the oil pump air, this time spit out the pipe on the gate valve should be closed. Stanford, the heat transfer oil to be heated evenly before driving, preheating is the use of the heat transfer oil is continuously through the pump body. Thermal Standard: Hot pump casing temperature not lower than the inlet oil temperature 40 ℃, preheat speed of 50 ℃ /, warm-up pump should be on the side nut on the loose 0.3-0.5 mm, preheating should be completed Tighten. â…¡. Turn on the first, a comprehensive inspection of the preparation is complete.Second, turn on the power, when the hot oil pump to achieve positive speed, and the instrument showed considerable pressure, and gradually open the output valve on the pipeline, and adjust to the need conditions.In the output In the case of pipeline valve closed, the pump can not work continuously for more than 3 minutes.Three hours after the first run 3-4 hours, the equipment is heated to operating temperature, turn off the hot oil pump, check the hot oil pump shaft and the motor coupling Concentricity, shaft and motor shaft deviation should be controlled within the allowable range, the pump shaft rotation should be lightweight and flexible and vibration-free rotation, if not meet the above requirements, should be re-adjusted. Always pay attention to motive power readings and vibration conditions, the vibration value does not exceed 0.6 mm, if the abnormal shutdown should be checked. (The correct use of hot oil pump)
