The operation of stainless steel tank mainly includes the inspection work, operation process, repair and maintenance and matters needing attention. The detailed process is as follows. 1, check the preparation 1.1 point mixing motor, see if there is abnormal movement and oil leakage phenomenon. 1.2 check the tightness of each valve and check the sealing system to prevent oil leakage. 1.3 check electrical appliances are in good condition, there is no leakage phenomenon. Check whether the safety valve, pressure gauge, temperature gauge, vacuum gauge, etc. are in good condition. 2. Batch tank operation process 2.1 turn over the vacuum valve, when the vacuum reaches-0.04 MPA, turn over the inlet valve, according to the process of using the vacuum to pump the pre-processed liquid. 2.2 open the inlet valve, pump purified water to process requirements, open the exhaust valve, break the vacuum. 2.3 turn on the main power switch, turn on the mixer motor switch and mix well. Now Open the hand hole to put solid powder. Add End, seal, and continue mixing. 2.4 when the liquid medicine needs to be heated, open the jacket steam valve, open the trap at the same time, the pressure is controlled below 0.10 MPA, when not in use, close the steam valve, then close the trap. 2.5 when the medicine liquid cools, open the bottom water inlet valve and the water outlet valve of the jacket for cooling, close the water inlet valve and the water outlet valve when it is not needed, and clean it in time after use. 2.6 pay attention to the pressure of the pressure gauge so that it is kept at 0.1 MPA, to reach the heating requirements closed steam valve. 2.7 mixing the end of the closed motor switch, closed the power master brake, turn over the open valve for discharging. Frequently check the tightness of welds, pipes, level gauges, valves and manholes. 3.2 always check the activity of thermometers and pressure gauges. 3.3 check that the safety valve is active and the trap is open. 3.4 overhaul cycle for a year, overhaul of all transmission parts to replace the rolling bearing, should be replaced in a timely manner, add butter lubrication, cover the oil hole. Notice 4.1 when the equipment is out of order, the remaining steam in the tank should be exhausted and can not be repaired under pressure. 4.2 prevent liquid from spilling onto the motor during repair. 4.3 timely cleaning of equipment at end of service.
