Airtight machines are widely used products in industry. The airtight machine is used to find out whether there is an air leakage problem. This is more important for many products, so it is also important to use the airtight machine correctly. Problems can easily arise during the inspection process if the operation is not performed properly or if the correct operation method is not known. So how to better use the airtight machine? The following will introduce the correct operation method to you.

During the pressurization process, the pressurization should not reach the specified pressure range all at once, but should be carried out slowly. When the pressure reaches 0.5mpa, stop for 5 minutes to check whether the pressure drops; when the pressure reaches 1.5mpa, stop for 5 minutes to check whether the pressure drops; when the pressure reaches the specified pressure, record the ambient temperature and pressure; If the pressure does not drop, it is qualified. If the pressure in the above three steps drops, it means that the refrigeration unit is leaking and needs to be inspected and repaired. After standing, the pressure will change with the temperature. Every time the temperature changes by 1 degree, the pressure will change by about 0.1mpa, which should be corrected when the pressure is checked later.

Of course, in addition to knowing how to use the airtight machine better, we must also pay attention to the corresponding problems during use, such as not using refrigerant, oxygen, flammable and toxic gases as pressurized gases; Apply pressure at both ends; use a pressure gauge with a corresponding pressure rating greater than the design pressure. These are noted, I believe the surgery will be very effective. We are a professional manufacturer of airtight machines, worthy of your trust.
