Asphalt heat preservation pump shaft is equipped with stuffing box at the front end, the sealing performance is more reliable, meanwhile, there is a mechanical sealing device in the bearing seat, so a large amount of leakage can not appear, and a small amount of leakage can be discharged through the leakage nozzle to receive.
1, a small amount of leakage in the early start of the operation is normal, after a certain period of sealing surface running leaks will reduce or stop, downtime: cut off the power. The asphalt insulation liquid pump venting, cleaning and the impeller should be periodically rotated 180 degrees to prevent shaft deformation until the pump is completely cooled so far. Do not use the input valve on the gate to regulate the flow, to avoid cavitation, pay attention to the operation of the heat pump has no noise, if the pilot state is found to be promptly processed.
2, Asphalt heat pump has a good use of the structure, in the use of performance plays an important role and performance, can fully demonstrate the use of good performance advantages, in accordance with the actual development trend of good development. Often check the loose bolts of the situation, the heat pump casing temperature and inlet temperature are the same, the export pressure gauge fluctuations and pump vibration.
3, asphalt insulation pump should not be less than 30% of the design flow under continuous operation, if you must operate under the conditions, it should be installed in the bypass bypass pipe, and the flow to reach the above minimum, the transmission medium to the bitumen insulation pump The heat on the pump cover and bearing dissipates heat from the surface of the pump cover and bearing housing to adapt the temperature of the bearing housing to the temperature of the shaft sealing performance. Therefore, the choice of heat transfer oil pump installation location, make the pump cover and bearing seat of the heat for easy proliferation, does not appear any heat storage.
4, the bearing seat is provided with two ball bearings, by the pump heat pump insulation pump impeller side of a ball bearing with the heat transfer oil lubrication, by the coupling side of a ball bearing is lubricated with high temperature grease: each Ball bearings running 3000 hours, you must remove the clean with diesel, check the contact surface is damaged, if damaged, you must replace the new bearing. When installed by the ball bearing on the impeller side, the side with the dust cover should be installed toward the impeller, and the bitumen heat pump should be injected before starting to lubricate. On the coupling side of the ball bearings, the use of complex calcium-based high-temperature grease (ZFG-4), the re-install the bearing, with dust cover side also toward the impeller side installation, install the grease (about 1 / 2 ball bearing and housing space). After 48 hours of operation, use a grease gun to inject replenishment grease into the pressure cup on the bearing cap.
