The main application of thermal oil pump oil and chemical industry; oil industry; synthetic fiber industry; textile printing and dyeing industry; plastics and rubber industry; paper industry; timber industry; construction industry and machinery industry; food industry; pharmaceutical production; hot oil heating cycle system is widely used. However, if the temperature reaches above 400 degrees, you should pay attention to the following points when using the heat transfer oil pump: 1, Turn on the power, turn on the switch of related instruments; When the pump reaches the normal speed, and the instrument shows a considerable pressure, Gradually open the gate valve on the output line and adjust to the required condition. 2, just started running, the production process equipment slowly heated to 100-130 degrees, the external lubrication of the gear pump, high temperature heat transfer oil pump and in the case of the output valve on the pipeline closed, the pump can not work continuously for more than 3 minutes; Keep at the temperature to continue running dehydration degassing the oil in the HTF completely evaporated before heating the equipment to the operating temperature; 3, the boot process, always pay attention to the motor power readings and vibration conditions, the vibration value does not exceed 0.6mm, if there is abnormalities should stop inspection; 4, in the first 3-4 hours of operation, the equipment is heated to operating temperature, turn off the pump, check the pump shaft and motor shaft coupling coaxiality, pump shaft and Motor shaft deviation should be controlled within the allowable range, the pump shaft rotation should be lightweight and flexible and no vibration rotation, hot oil pump, such as not meet the above requirements, high temperature gear pump should be re-adjusted; 5, by impeller-side ball bearing installation When the high-temperature heat-conducting oil pump has a dust cover on the side toward the impeller installation, before driving into the thermal oil lubrication; by the coupling side of the ball bearings, with complex calcium-based high temperature grease When reinstalling the bearing, heat pumps have the same side of the dust cover side toward the impeller to be installed, the installation grease filling. 6, each ball bearing running 3000 hours, you must remove the diesel fuel clean, check for damage, if damaged, you must replace the new bearing; heat pump for conveying solid particles without high temperature liquid. To ensure the full performance of the pump and have a good life, according to the correct operation of the above matters to extend the service life of high temperature hot oil pump.
