The vacuum packaging machine is an indispensable packaging machine on our production line. In particular, most of the products on the market today are vacuum-packed. It can be seen how much demand for vacuum packaging machines is, but many friends do not know about vacuum packaging machines. It is the installation and use of the vacuum pump in the vacuum packaging machine, so how to install and use the vacuum pump of the vacuum packaging machine? Let me introduce it in detail below.
1. There are two ways to install the vacuum pump of the vacuum packaging machines, one is the built-in type, usually XD-020, XD-040 single-stage rotary vane vacuum pumps, and generally the 400 type packaging machine uses XD-020 pumps. The other is an external type, usually a 2X-15 two-stage rotary vane vacuum pump. This pump has a faster pumping rate and a higher vacuum than a single-stage pump. It is generally suitable for large production batches and higher vacuum requirements. Install outdoors to reduce exhaust pollution.
2. The vacuum gauge is usually axially forward and installed on the operation panel or on the front of the fuselage. It is usually ￠60 gauge with an accuracy of 2.5; ￠100 gauge with an accuracy of 1.5.
3. Two vacuum solenoid valves are usually used, one is ￠5 two-position three-way solenoid valve, which is mainly used to control the upper and lower displacement of the hot-pressing sealing device.
