What should be paid attention to after the end of the heat transfer oil heat exchanger?


The heat of the heat transfer oil heat exchanger is generated and transmitted by the electric heating element immersed in the heat transfer oil. The heat transfer oil is used as the medium, and the circulating heat pump is used to force the heat transfer oil to perform liquid phase circulation, and the heat is transferred to one or more heat devices. After being unloaded by the heat equipment, it is again passed through the circulation pump, and then returned to the heat transfer oil heater to absorb the heat, and then transferred to the heat equipment, so that the heat is continuously transmitted, and the temperature of the heated object is raised to reach the heating process. Claim.


    After the pressure piping of the heat transfer oil heater is finished, the piping system should be purged. Before the purge, the orifice plate, filter screen, check valve, etc. of the piping system should be removed, and measures should be taken to prevent the dirt inside the pipeline from being blown into the heat equipment. Compressed air is used as the washing medium, the pressure should not exceed 0.5Mpa, and the flow rate should be no less than 20m/s. After the heat transfer oil heater is tested and purged, the system can immediately refuel. First, the pump inlet, system outlet and system valve are opened. The exhaust valve of the valve between the upper part of the heater and the expansion tank is opened, and then the oil is refueled from the expansion tank. In the process, pay attention to the system exhaust, to ensure that the system is full of oil, and finally make the expansion tank liquid level up to one-third.
