The front end of the heat-conducting oil pump shaft is provided with a stuffing box, the sealing performance is more reliable, and the mechanical sealing device is arranged in the bearing seat. Therefore, a large amount of leakage can not occur, and a small amount of leakage can be discharged through the leakage nozzle to receive. It is normal to have a small amount of leakage early in operation, and the leakage will decrease or stop after the sealing surface has run through a certain period of time. Transmission medium to heat pump oil pump cover and bearing the heat from the pump cover and bearing surface cooling, so that the bearing temperature to adapt to the shaft sealing performance temperature. 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. Two ball bearings are provided in the bearing housing. A ball bearing on the pump impeller side of the heat transfer oil pump is lubricated with the heat-conducting oil delivered. A ball bearing on the coupling side is lubricated with high-temperature grease. Each ball bearing 3000 hours after operation, you must remove the clean with diesel, check the contact surface is damaged, if damaged, you must replace the bearings. When mounted on the impeller-side ball bearing, the dust-proof cover must be mounted on the side facing the impeller and lubricated with heat-conducting oil before starting up. On the coupling side of the ball bearings, the use of complex calcium-based high-temperature grease, the bearings re-install, the dust-proof side also toward the impeller side installation, filling grease when installed. After 48 hours of operation, use a grease gun to inject replenishment grease into the pressure cup on the bearing cap. Do not use the input pipe gate valve to regulate the flow, to avoid cavitation. Conductive oil pump should not be less than 30% of the design flow continuous operation, if you must operate under the conditions, it should be installed in the bypass bypass pipe exports, and to flow above the minimum. 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. Note that there is no noise in the operation of the heat transfer oil pump, such as the pilot state should be promptly found. Shutdown: cut off the power. The heat transfer oil pump liquid venting, cleaning and should regularly rotate the impeller 180 degrees to prevent shaft deformation until the pump is completely cooled so far.
Human Monkeypox Virus (MPV) Antigen Rapid Test Device (colloidal gold) is an in vitro diagnostic test for the qualitative detection of human monkeypox virus antigens in Nasopharyngeal swab,saliva and exudate of blain using the rapid immunochromatographic method. The identification is based on the monoclonal antibodies specific for the human monkeypox virus antigen. It will provide information for clinical doctors to prescribe correct medications.
