With the acceleration of the urban industrialization process, people find that the air quality in the city is getting worse and worse. This is mainly due to the worsening of the air quality caused by industrial pollution. Everyone knows that pure oxygen is very good for the human body, so the application of various medical oxygen generators and oxygen generators for home has become more and more extensive. Today I will take you to understand the difference between the two.

The medical oxygen generator, as the name implies, is a medical device. It has been tested by the National Food and Drug Administration, approved, and issued with a medical device license. It is mainly used in respiratory and circulatory diseases, such as chronic bronchitis, asthma, emphysema, pulmonary heart disease, Chronic obstructive pneumonia, and so on. The general medical oxygen generator is different. It is used for family health care and physical therapy. It is not a medical device. This is the difference between the two in terms of use.

In principle, whether medical oxygen generator or household oxygen generator, molecular sieve pressure swing adsorption technology is generally used, air is used as raw material, and nitrogen is separated from the air through molecular sieve filtration to obtain a higher concentration of oxygen to produce oxygen. It has the characteristics of ready-to-use. In this sense, there is no essential difference between household oxygen generators and medical oxygen generators. Molecular sieve oxygen generation is the mainstream oxygen generation method. In the past, oxygen-enriched membrane oxygen generators, chemical oxygen generators, and electronic oxygen generators have gradually been used. The trend of elimination.

The main difference between a household oxygen generator and a medical oxygen generator is the oxygen generator capacity of the oxygen generator. The oxygen concentration of a typical household oxygen generator is only 30%~90%, while for health-care oxygen inhalation, 1~5L is This concentration is sufficient for health care oxygen standards. The oxygen concentration of medical oxygen concentrators can reach about 93%, which is higher than ordinary household oxygen concentrators and meets the medical grade oxygen standard 1L~3L, which is not achieved by household oxygen concentrators.

The personnel involved in the daily management and maintenance of oxygen supply equipment must be serious, and realize the importance of this work from the death penalty. In actual work, frequent inspections, repairs, and maintenance are necessary to eliminate possible failures in the bud.

• 

• 

Engineers and technicians have a huge responsibility. Only in accordance with their operating procedures and experience, can they ensure safe clinical use of oxygen, extend the service life of the equipment, benefit people’s health, improve the efficiency of the hospital, and reduce medical risks.

Therefore, for people suffering from diseases, the use of medical oxygen generators can play a better role in the treatment of diseases. After all, medical oxygen concentrators are superior to household oxygen concentrators in all aspects. But if it is only used for daily oxygen therapy and health care, you can choose a household oxygen generator. After all, relative to the high price of medical oxygen concentrators, household oxygen concentrators are more easily accepted by ordinary people.

Shot blasting and sand blasting are two cleaning methods, and many people are a little stupid and confused. Today, we will give you a detailed introduction:

First, let’s introduce the similarities

Shot blasting machines and sand blasting are both surface treatments. Both use compressed air as power to spray sand or shots onto the surface of the material to achieve removal and a certain degree of roughness, which can clean and decontaminate the workpiece.

• 

• 

2. Difference

The shot blasting machine, hence the name implies, is the method by which the centrifugal force generated when the shot material rotates at a high speed is used to impact the surface of the material to achieve removal and a certain degree of roughness. The thrown material pellets are generally spherical particles without edges, such as steel wire cut pellets. The sandblasting machine, also from the name, is to spray sand or pellets to the surface of the material by using compressed air as the power to achieve removal and a certain degree of roughness. The blasted material sand refers to the angular sand, such as brown corundum, white corundum, river sand, and so on.

• 

• 

3. The working principle of shot blasting machine and sand blasting machine

The working principle of the shot blasting machine is to use the centrifugal force of the high-speed rotating impeller to throw small steel shots or small iron shots out to hit the surface of the part at high speed, so the oxide layer on the surface of the part can be removed. At the same time, a steel shot or iron shot hits the surface of the part at high speed, causing the lattice distortion on the surface of the part to increase the surface hardness. It is a method of cleaning the surface of the part. Shot blasting equipment is often used to clean the surface of the casting or to clean the surface of the part. Strengthen processing.

The portable sand blasting machine is a method that uses compressed air to blow out the quartz sand at high speed to clean the surface of the parts. It is also called sand blowing in the factory, which not only removes dust, but also removes oil by the way, which is very useful for painting. The general sandblasting machine has various specifications of sandblasting guns, as long as it is not a particularly small box, you can put the gun in to clean it.

• 

• 

4. What is the difference in application areas?

Shot blasting equipment makes the surface of the workpiece reach a certain degree of roughness, makes the workpiece beautiful, or changes the welding tensile stress of the workpiece to compressive stress to increase the service life of the workpiece. Almost used in most fields of machinery, shipbuilding, auto parts, aircraft parts, guns and tanks, bridges, steel structures, glass, steel plates, pipes, and so on. The working surface of the steel plate of the car we ride daily is strengthened by shot peening, which can significantly improve the fatigue strength of the material.

• 

• 

Sand blaster machine (ore used in shipbuilding and repairing industries) is mostly used informed ships or sections. The function is to remove the old paint and rust on the steel plate and repaint it. In the ship repair and shipbuilding industry, the main function of shot blasting and sand blasting is to increase the adhesion of the steel plate coating paint. Sandblasting equipment is used for complex shapes, easy to remove rust by hand, low efficiency, poor site environment, and uneven rust removal. The general sandblasting machine has various specifications of sandblasting guns, as long as it is not a particularly small box, you can put the gun in to clean it. The supporting product of the pressure vessel—the head adopts sandblasting method to remove the oxide scale on the surface of the workpiece. The diameter of quartz sand is 1.5mm～3.5mm. One kind of processing is to use water as a carrier to drive the emery to process the parts, which is a kind of blasting. sand.

• 

• 

How to choose wet wipes making machine?

1. The selection of wet wipes making machines can be determined according to the allowable output, packaging weight, packaging speed, and packaging size. The length of the product and its composition analysis determine how many packages per minute the packaging design speed can reach. The wet wipes making machine performs a series of operations such as folding, forming, bagging, adding liquid, and sealing the non-woven fabric to output the finished product.

2. When purchasing wet wipes manufacturing machine, users will pay more attention to the price, but not only the price. If you only care about the price, you may be deceived when you pay attention to the packaging machine. Some wet wipe machines are very cheap, because the components of the wet wipe machine and the packaging machine have different internal principles, so their service life is also different.

• 

• 

3. When purchasing a wet wipes manufacturing machine, you should try to choose a manufacturing company with R&D capabilities and ensure after-sales service. If the wet wipes making machine is used for a long time, especially in the case of continuous operation and overload, some electrical and mechanical failures are prone to occur, such as improper sealing, shutting down, and leaving the machine, and blowing the fuse during startup. It also emits noisy noise during operation, uncontrollable temperature, deformation and bending of the finished packaging bag at the seal, and bubbles or irregular marks on the stamping part of the sealing knife. Therefore, the wet wipe machine needs to be maintained and maintained daily to extend its service life.

The sandblasting machine is a method that uses compressed air to blow out the quartz sand at high speed to clean the surface of the part. It not only removes dust, but also removes oil incidentally, which is very useful for painting. It is often used to remove rust on the surface of parts; to modify the surface of parts (the small wet sandblasting machine sold on the market is for this purpose, the sand is usually corundum, and the medium is water); in the steel structure, the application of high-strength bolts for connection is a relatively advanced Method, because the high-strength connection uses the friction between the bonding surfaces to transmit force, the quality of the bonding surface is very high. At this time, a sand blasting machine must be used to process the bonding surface.

• 

The sandblasting machine is used for complex shapes, easy to remove rust by hand, low efficiency, bad on-site environment, and uneven rust removal. The general sand blasting machine has various specifications of sand blasting guns, as long as it is not a particularly small box, you can put the gun in to clean it. The supporting product of the pressure vessel—the head adopts sandblasting method to remove the oxide scale on the surface of the workpiece. The diameter of quartz sand is 1.5mm～3.5mm.

1. Workpiece coating and pretreatment of work-piece bonding sand blasting machine can remove all dirt such as rust on the surface of the work-piece, and establish a very important basic pattern on the surface of the work-piece (the so-called rough surface). Moreover, it is possible to change the abrasives of different particle sizes, such as the abrasives of the flying-spread abrasives, to achieve different degrees of roughness, which greatly improves the bonding force of the workpiece with the coating and the plating material. Or make the bonding part stronger and better quality.

• 

• 

2. Cleaning and polishing of rough surfaces of castings and workpieces after heat treatment. Sandblasting can clean all dirt (such as oxide scale, oil stains, etc.) on the surface of castings and forgings and workpieces after heat treatment, and polish the surface of the workpiece to improve the smoothness of the workpiece. It can make the workpiece show a uniform and consistent metal color, and make the appearance of the workpiece more beautiful and beautiful.

3. Burr cleaning and surface beautification of machined parts. Automatic sandblasting machine can clean up the tiny burrs on the surface of the workpiece and make the surface of the workpiece smoother, eliminating the hazard of the burr and improving the grade of the workpiece. And sandblasters can make small round corners at the junction of the surface of the workpiece, making the workpiece more beautiful and more precise.

• 

• 

4. Improve the mechanical properties of the parts. After the mechanical parts are sandblasted, they can produce uniform and fine uneven surfaces on the surface of the parts, so that the lubricating oil can be stored, so that the lubrication conditions are improved, and the noise is reduced to increase the service life of the machine.

5. Light decoration function For some special purpose workpieces, sandblasters can achieve different reflections or matt at will. Such as the polishing of stainless steel workpieces and plastics, the polishing of jade, the matting of the surface of wooden furniture, the pattern on the surface of frosted glass, and the texturing of the surface of the cloth.

6. Small investment, quick return, high reliability, simple and convenient maintenance.

• 

• 

Before you buy a mini roller compactor

1. Customers must understand the requirements of different mini roller compactors in the working environment before purchasing. If you want to obtain a uniform compaction density, you can choose a tire-type road roller. The tire-type road roller does not destroy the original viscosity of the soil when it is rolled and has good bonding properties between the layers of soil. The front-wheel can swing, so the compaction is more uniform and there will be no false compaction. If the asphalt pavement is compacted and smooth, a full-drive roller compactor should be used. In areas where the roller compactor’s compaction capacity is not high, road rollers with low line pressure and flexibility can be used.

2. Choose according to the condition of the material. If the compacted material is a mixture, choose a vibratory roller; if it is clay, use a tamping road roller; if it is a shallow rolling of the material, you can choose a static roller. Force-acting roller compactor.
