Hot oil pump for conveying solid particles without high temperature liquid. The degree of corrosion resistance and temperature depend on the material used to contact the main parts of the media (divided into three categories: 1, HT200; 2, ZG230-450; 3,1 Cr18Ni9Ti, 0Cr18Ni12Mo2Ti). Heat pump main petroleum 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, heating oil heating system is widely circulated application. To ensure the full performance of the pump and have a good life, when using the hot pump, should pay attention to the following aspects: 1, open the relevant instrument switch; 2, connected to the power supply, when the pump reaches the normal speed, and the instrument After showing considerable pressure, gradually open the gate valve on the output line and adjust to the required conditions. In the output pipeline valve closed, the pump can not work continuously for more than 3 minutes; 3, just started running, the production process equipment slowly heated to 100-130 degrees, hot oil pump and continue to maintain the temperature Run dehydration degassing to the oil in the heat transfer oil completely evaporated before the equipment is heated to operating temperature; 4, 3-4 hours before operation, the equipment is heated to operating temperature, turn off the pump, check the pump shaft and Motor shaft coupling coaxiality, shaft and motor shaft deviation should be controlled within the allowable range, hand shaft rotation should be light and flexible and vibration-free rotation, hot oil pump if the above requirements are not met, should be re-adjusted; 5, the boot process, we must always pay attention to motor power readings and vibration conditions, the vibration value does not exceed 0.6 mm, if there is abnormal parking should be checked; 6, after each ball bearing operation 3000 hours, you must remove the clean with diesel After checking whether the damage, if damaged, you must replace the bearings; 7, by the impeller side of the ball bearing installation, the hot oil pump dust cover on the side toward the impeller installation, driving 8, by the coupling side of the ball bearings, with complex calcium-based high-temperature grease, the bearing re-install, hot oil pump dust-proof side also toward the impeller side installation, installation, filling lubrication fat.
