Small vacuum pump use - automatic vacuum packaging machine

1, before the normal operation of the vacuum pump in the vacuum packaging machine, should to a test of vacuum pump, and check whether there is a vacuum pump abnormal vibration and impact noise. Using a vacuum pump for the first time should also determine the limit of the vacuum pump pressure, the extreme pressure should comply with the technical specifications. In the case of long-term use of vacuum pump, vacuum pump temperature should not exceed 70 degrees.

2, need through the equipment of vacuum pump cooling water, must first before start by cooling water, and then start again. The temperature of the cooling water outlet should not exceed 30 degrees.

3, continuous vacuum pump and pumping system of pipeline should be as short as possible and coarse, and the inner diameter of the pipe, generally should not be less than the diameter of the vacuum pump inlet, lest affect pumping pipe resistance caused by great speed.

4, in order to keep the workshop clean and health, it is advantageous to the health of workers, hoses are used in the exhaust gas directly led to the outside.

5, if the vacuum pump for a long time does not work or the ambient temperature is lower, could lead to a difficult start. At this point, the use of vacuum water pump suction port shall be submitted to the atmosphere in the wind rotation pulleys. In the absence of power rotation after a few weeks, will start the vacuum pump. Using a vacuum pump, you can continue to run a few times, motor will be stored in the oil into fuel tank vacuum water pump cavity, then start. If not, you can use the direct radiation heating or heating vacuum pump, until it can be moved.

6, before using, check whether the equipment of vacuum pump oil to the oil line position of the window. At the same time, you have to check the direction of rotation of the motor pulley.

7, after the completion of the work, should be shut off air valve, then close the low valve, then close the rotary-vane vacuum pump, then exhaust, in order to prevent gas leakage. Oil return vacuum system. Finally, should cut off the main power supply, and stop the water supply.

At a time when technology is essential for water pump, ensuring that it works in a symbiotic way with your human employees is key.
