1. When purchasing, the packaging of solid and granules is relatively dry and non-corrosive. It can be made of aluminum alloy, and the package is filled with soup. For materials with high salt and acid content, stainless steel or aluminum-magnesium can be used. Alloy material. The sealing ring is generally made of silicone rubber and black rubber. A few low-grade products use foam rubber. The silicone rubber has high temperature resistance, corrosion resistance, good sealing performance and long service life. The foam rubber has poor sealing performance, easy to fall off and short service life.
2, electrical components must be selected to regulate the products of low-voltage electrical manufacturing enterprises to ensure safety, reliability, durability, because the electrical control part is the brain of the packaging machine.
3. The design of the whole machine should be reasonable and beautiful, and meet the professional standardization requirements of mechanical and electrical products (or vacuum packaging machines). It has basic safety. All kinds of warning signs must be complete and marked at key positions. The nameplate must be marked. Equipment number, date of manufacture, technical parameters, and implementation standards.
4. When purchasing equipment, technicians with certain electromechanical knowledge can observe the vacuum packaging machine of the model you want, and understand the equipment in many aspects. Beware of the practice of simply selecting the machine from the outside.
An oxygen concentrator is a type of medical device used for delivering
oxygen to individuals with breathing-related disorders. Individuals
whose oxygen concentration in their blood is lower than normal often
require an oxygen concentrator to replace that oxygen.
Generally,
you can`t buy an oxygen concentrator over the counter. A doctor must
prescribe it after they`ve completed a thorough medical evaluation. The
doctors will also typically show the patients how to effectively use
these concentrators while traveling and in their home.
Oxygen
concentrators filter surrounding air, compressing it to the required
density and then delivering purified medical grade oxygen into a
pulse-dose delivery system or continuous stream system to the patient.
It`s also equipped with special filters and sieve beds which help remove Nitrogen from the air to ensure delivery of completely purified oxygen to the patient. These devices also come with an electronic user interface so you can adjust the levels of oxygen concentration and delivery settings. You then inhale the oxygen through the nasal cannula or special mask.
