Common vacuum pump safe operation process

Vacuum pumping machine has many kinds, including household and micro and so on, today's small compilation mainly explains the common vacuum pump safety operation process: 1, pre-operation preparation: first of all, the equipment should be placed in a horizontal, ventilation, drying place, the vacuum unit pumping port and pumped system connected well, seal must be tight, there should be no leakage point.
check that the oil levels in the vacuum pump and the Roz pump and the lubricants in the oil cups meet the requirements and connect the power and ground wires.
check for other unsafe factors.
2, the operation of the unit start-up operation: on the main power switch, the main power LED on, put the control mode in the manual or automatic position, press the control power button, the light light (vacuum pump, booster pump and emergency stop button should be reset, otherwise the control power button can not be switched on), such as the power supply sequence error yellow light on, need to be replaced.
the vacuum pump circuit breaker, press the vacuum pump control button, the vacuum pump indicator is on, and the vacuum pump is running.
the delay of the booster pump according to the actual situation (through the time relay, the adjustment range is 1-6 minutes).
the booster pump circuit breaker, press the booster pump control button, the booster pump light is on, and the booster pump is running.
the oil level switch in the well, the beehive on the control panel will automatically alarm when the well enters the vacuum pump oil or transformer oil, and the system will shut down.
3, shut down the shutdown: close the high vacuum butterfly valve a close the mechanical booster pump a close the vacuum pump a press the emergency stop button, control the power off a main power circuit breaker.
when the control mode is switched to the automatic position by means of the knob on the control disc, the device automatically controls the closing and starting of the vacuum pump and the mechanical booster pump through the preset control points of the vacuum relay.
