Six main points and matters needing attention in the use of vacuum oil filter
Description of the use of vacuum oil filter
1. connect the inlet and outlet oil well and close all the valves.
2. according to the size of the total power of the machine, the three phase and four wire power supply is well connected. The point "vacuum opening" makes the vacuum pump and the oil pump turn to the arrow pointing to the direction of the arrow. To connect the safe ground, check whether the circuits are connected reliably, whether the valves are opened, and the point moving vacuum pump, the oil pump, the oil pump and the oil exhaust pump should not be stuck and eccentric vibration. The type of condenser can be injected into the water storage room through the drain valve, and the operation procedure is ready after the operation is ready.
3. first start the vacuum pump, when the vacuum surface reaches the negative pressure -0.08MPa, it can open the oil intake valve and enter the oil until the oil of the vacuum tank reaches the middle line position of the oil mark. (avoid the oil suction in the vacuum pump, otherwise the equipment can not operate normally. If the oil is ininhale into the vacuum pump, the oil should be released from the vacuum pump in time and then added to the pump. Appropriate vacuum oil), after opening the oil discharge valve, the oil pump switch can be started. The filter and regeneration function of the machine can be selected arbitrarily. As long as the ball valve can be switched, the oil filter impurities will begin to make the normal circulation of the oil road.
4. when working normally, observe the oil pipe regulating the oil intake valve to keep in and out of the oil balance, open the heater switch, set the temperature needed to heat the oil, volatilize the water in the oil, if the oil in the oil can increase or the oil pump is slow when the oil is more water, it is necessary to open the vent valve to control the suitable vacuum degree at this time. When the water content is reduced, the oil level is lowered or the oil discharge pump is normal, the vacuum valve is adjusted at about 0.08MPa. At this time, attention should be paid to the reaction of the instruments. If the readings of the pressure gauge are greater than 0.4MPa, it is necessary to clear and replace too much impurities on the surface of the filter core in the filter.
5. stop the heating system for 3 minutes while shutting down, then stop the vacuum pump and pump, close the inlet valve and stop the oil pump after the remaining oil is discharged.
6. open the vent valve to reach the normal atmospheric pressure, exhaust the oil in the cylinder, the remaining oil from the oil release valve, to prevent the next use of the different types of oil in the next use, finally shut off the air switch.
