How to choose an oxygen generator?

 Medical oxygen generator has now become one of the main oxygen sources for oxygen supply in medical centers. It not only has low cost but also provides a continuous oxygen supply. It has become the choice of many hospitals, including some community hospitals.

A medical oxygen generator is a technical product that uses the principle of pressure swing adsorption to separate air. The compressed air purified by an air purification dryer enters the bottom of the adsorption tower. The tower is filled with zeolite molecular sieves that have a strong adsorption capacity for nitrogen under a certain pressure. When passing through the zeolite molecular sieve adsorption bed, nitrogen is adsorbed, while oxygen is enriched at the top of the tower body. As a product output, the system is equipped with two adsorption towers, one tower absorbs oxygen, and the other tower desorption regeneration, alternating cycles, and continuous production oxygen.


Points to pay attention to when purchasing an industrial oxygen generator:

1: The oxygen purity is not less than 90%

The purity of medical oxygen shall not be lower than 93%, and the purity of medical molecular sieve oxygen generator shall not be lower than 90%. If the oxygen concentration is too low, it will be useless for oxygen therapy.

2: Has an unchangeable accumulative timing function

The cumulative timing function is a reflection of product quality and an important basis for consumers to repair when a product fails. Generally, the service life of the oxygen generator machine is required to reach more than 10,000 hours.

3: The noise during operation is less than 45 decibels

When the product is running continuously, the noise is less than 45 decibels, which can avoid affecting the sleep and rest of oxygen users and their families. This principle is especially important at night.

4: The compressor displacement is large enough

The compressor displacement should reach 3.8 to 4.2 cubic meters per hour. If the exhaust volume is too small, the oxygen concentrator generator wears quickly, resulting in a rapid decrease in oxygen concentration. The compressor cup is best imported from abroad.


5: The molecular sieve is best to use foreign original imported parts

Molecular sieve is the core component of the PSA oxygen generator, which determines the performance and quality of oxygen generator.

6: With oxygen concentration monitoring and early warning function

An early warning is issued when the oxygen concentration is lower than a safe value, which can ensure the safety of oxygen inhalation for patients.

7: Have a good pre-sales and after-sales service

Many people use medical oxygen generators for the first time. Manufacturers or sellers should be able to answer basic questions about oxygen therapy for consumers. Oxygen machine is different from general home appliances in that it lacks a repair site, so it is required that when the product fails, it should be able to easily exchange, return or maintain and repair.

What is the difference between a shot blasting machine and sand blasting machine?

Image
  Shot blasting machine is generally used for regular shapes, etc., several blasting heads are up and down, left and right, high efficiency and low pollution. In the shipbuilding industry, shot blasting and sand blasting machines are commonly used. However, both the shot blasting machine and the sand blasting machine uses compressed air. Of course, it is not the floor shot blasting machine that has to use a high-speed rotating impeller. In shipbuilding and shipbuilding industries, floor shot blasters are generally used for steel plate pretreatment (removal of rust before painting); shot blasting equipment (ores used in repairing and shipbuilding industries) are mostly used for shaped ships or sub-parts. The function is to remove the old paint and rust on the steel plate and repaint it. In the shipbuilding and shipbuilding industry, the main function of shot blasting equipment and automatic sandblasting machine is to increase the adhesion of steel plate coating paint. In fact, t...

  water well drilling rigs Water well drilling rigs are easy to move, small in size, and high in work efficiency. They are fully hydraulically controlled for lifting, outriggers, lifting, and other processes. Drill pipes can be replaced without stopping the machine. It can meet various geological conditions such as soil, well-drilling sand, and rock pebble layers. Structure, equipped with high-power hydraulic motor, high torque, fast drilling speed. Water well drilling machine is suitable for complex formations such as soil layer, rock layer, pebble layer, cemented pebble layer, etc. Water well drilling rigs are widely used in foundation engineering construction of high-rise buildings, large bridge projects, water conservancy construction, farmland engineering, and other fields. Small water well drilling rigs are suitable for building pile foundations, high-tension line tower pile foundations, dam foundation drilling, drilling water wells, agricultural irrigation wells, and engin...

How are nitrile gloves produced?

Image
Nitrile gloves are mainly made by dipping nitrile latex, molding, vulcanizing, surface treatment, dust-free cleaning, and other processes. The specific production process is as follows: First of all, the material for making nitrile gloves is nitrile rubber, which is formed by the emulsion polymerization of butadiene and acrylonitrile. Then, the hand-washing mold: the hand-washing mold needs to be pickled first, washed first, alkali washed, and then washed. After washing the hand mold, it should be dried or dried before entering the next process. The third step is to impregnate the nitrile latex to shape the glove. That is, the hand mold is immersed in a container filled with nitrile, heated at a high temperature, and dried after forming the glove. Next, we need to prepare the gloves to curl to facilitate putting on and taking off the gloves. After the above steps, the nitrile glove has been formed, but it has not been successful. A key step is needed: chlorine washing. Chlorine cleani...
