Vacuum pump of two operation modes
The core component of vacuum packaging machine is vacuum pump. There are many kinds of vacuum pumps, and the scope of application is also different. In this paper, we will not discuss the types of vacuum pump but the operation mode of vacuum pump. Generally, there are two working modes of vacuum pump, intermittent and continuous.
1. Intermittent operation mode is mainly applicable to semi-automatic vacuum packaging machine: the semi-automatic vacuum packaging machine relies on manual up and down or back and forth swing the cover, which determines that the size of the vacuum chamber should not be too large. The working mode of vacuum pump of semi-automatic vacuum packaging machine is intermittent. Only when the vacuum cover is closed, the vacuum pump will run, while the vacuum pump will not work at other times. The advantage of this control mode is to reduce power consumption and noise, while the disadvantage is that the pump has been started in a intermittent state, so there is certain wear on the pump, which requires the vacuum pump The quality of must pass the customs, customers in the purchase of vacuum packaging machine should not just look at the price, and ignore the quality of vacuum pump. If the quality of the pump is not up to standard, long-term use will lead to the phenomenon of slow vacuum pumping and poor vacuum effect.
2. The continuous operation mode is applicable to the automatic vacuum packaging machine: the automatic vacuum packaging machine controls the automatic swing of the cover through the air cylinder, and the air cylinder provides the pressure to the vacuum cover through the vacuum pump, so the vacuum pump is always in operation, which is one of the advantages of the automatic vacuum packaging machine. In addition, the automatic vacuum packaging machine has strengthened the treatment on the plate and the whole machine frame This is one of the reasons why the whole equipment size of the automatic vacuum packaging machine is larger than that of the ordinary vacuum packaging machine.
