中(zhong)譯(yi)英(ying)： Dissolution of the polyvinyl alcohol heating, should ensure that the workshop production equipment under the conditions of normal operation, avoid, return oil cooling rate is too large, resulting in electricity load transformer, burned, resulting in the accident.

Received notice in heating, the oil return temperature, normal to meet the normal operating under the premise of plant powder. Start the heat-conducting oil furnace feeding, draught fan for normal operation, in the setting of oil inlet temperatures near or below 2℃-3 ℃, the oil return temperature is below 200 ℃, open the heat exchanger, the oil return valve(to open the oil valve, oil valve after into) 2-3 wire. Preheat, ensure the heat-conducting oil furnace oil return temperature not lower than 200 DEG C, and preheating after 30 minutes, and then gradually open the heat exchanger, the oil return valve, the industrious observation oil into, oil return temperature decreases, the timely adjustment of inlet oil return valve, gradually boost to 3.5kg. Pressure reaches 3.5, should often observed heat exchanger pressure gauge reading changes, should try to keep the pressure of 3.5kg, according to the reading must be adjusted in time, change in the oil return valve. But the pressure shall not exceed 4kg, strictly avoid safety accidents.

After heating(ingredients post shall promptly notify), may not be fully closed valve should be opened into the heat exchanger, the oil return valve,1-2 wire. Preheating, try to keep the pressure of 1kg. Avoid heating inlet, oil return temperature falling too far, affect the normal operation of the equipment of workshop production workshop.
