The precision equipment used in the laboratory requires relatively high gas, and "oil-free compressed air" is a necessary gas. "Water lubricated air compressor" is one of the essential equipment. In the process of laboratory construction, the gas used in different laboratories is diverse.
The overall ventilation system of the laboratory is essential and cannot be ignored for special gas distribution systems
laboratory gas is mainly non-combustible gas (nitrogen, carbon dioxide), inert gas (argon, helium, etc.), flammable gas (hydrogen, carbon monoxide); highly toxic gas (fluorine, chlorine); combustion gas (oxygen) composition. Other gases except non-combustible gases and inert gases shall not be used in the laboratory.
"Water lubricated air compressor" can compress some special process gases, such as argon, nitrogen, coalbed methane and so on! Also known as: argon air compressor, nitrogen air compressor, coal bed gas air compressor.
as one of the important fields in the biomedical industry, the clean area or clean room required for aseptic production is divided into four levels according to the standard requirements, namely A, B, C and D.
Class A clean area, which belongs to high-risk operation area, including filling area, rubber stopper barrel placement area, open packaging container placement area directly contacting with sterile preparation, and operation area for assembly or connection operation under sterile conditions. Such area shall be equipped with one-way flow operation table (cover) to achieve the purpose of maintaining the environmental state of the area. Uniform air supply is required for the unidirectional flow system in its working area, and the wind speed is recommended to be controlled within the range of 0.36~0.54 m/s; verification activities shall be carried out for the operation state of unidirectional flow, and record documents (including test data) shall be provided; lower wind speed can be set and used in relatively closed isolation operator or glove box.
Class B clean area refers to the surrounding background-related area of Class A clean area for high-risk operations such as aseptic preparation and filling.
Class C and D clean areas, which refer to the clean areas required for relatively low-level operation steps in the sterile production process of drugs.
The verification of the clean area level of the medical workshop shall comply with the following basic principles:
(1) The certification of clean area level should include "static" and "dynamic" standards.
(2) Pre-test work shall be carried out before verification, generally including air flow or flow rate test, envelope leak test, filter leak test, air pressure test, etc.
(3) The number of sampling points is set to the square root of the area of the clean area or clean room (rounded to the nearest integer).
(4) The sampling amount of each sampling point is as small as the sampling amount = 20/Cn · m × 100 according to each sampling point (Note: Cn · m is the grade limit value of the larger considered particle size specified by the relevant grade). In addition, it is also necessary to satisfy that each sampling point is as small as a sampling amount of 2L, and the sampling time is greater than or equal to 1min.
(5) When the area is only required to be a sampling point, the point should be sampled ≥ 3 times.
(6) In order to effectively verify the cleanliness level of Class A clean area, the sampling volume of each sampling point shall not be less than 1m & sup3;.
(7) When verifying the cleanliness level, a portable dust particle counter with a shorter sampling tube should be used to prevent suspended particles ≥ 5.0 μm from settling in the long sampling tube of the remote sampling system. In a unidirectional flow system, an isokinetic sampling head should be used.
(8) Dynamic testing can be carried out during routine operation and medium simulation filling operation to prove that the dynamic cleanliness level is achieved, but the medium simulation filling test should require dynamic testing under "poor conditions.
Screw air compressor adopts pre-set configuration screw air compressor, only single power connection and compressed air connection, built-in cooling system, greatly simplifying the installation work. Screw air compressor has high efficiency, dimension-free
Generally, screw type air compressor is used to supply gas for laser cutting machine. The water-lubricated screw air compressor produced by Shanghai Granklin Group has stable air supply and long service time. Laser cutting machine industry, can not be separated from the gas demand, can be said to be perennial gas, so that it will cause the phenomenon of large power consumption. However, in recent years, the air compressor market has emerged, and energy-saving air compressors have solved the troubles for companies that use gas all the year round. Especially the permanent magnet variable frequency air compressor, constant pressure gas production, energy saving.
View detailsGenerally, there are relevant installation manuals for the installation of mechanical equipment. The same is true for silent oil-free air compressors. Whether the environmental quality is good or not, the silent oil-free air compressors need to pay attention to the installation environment and whether it affects the installation effect. need in sufficient light
Purchase oil-free air compressor to choose the brand, we are as far as possible to choose the best brand in China, the product quality and after-sales service ability of large factories are impeccable. In the domestic procurement of oil-free air compressors, you can consult the "Shanghai granklin group". water-lubricated oil-free air compressors are currently the mainstream oil-free air compressors in China. as a brand, granklin also has many application cases to visit, basically covering the whole industry.
View detailsContact information of oil-free air compressor manufacturers: At present, the main brands of oil-free air compressors in China are Granklin and so on.
As the screw oil-free and water-lubricated screw air compressor is a stainless steel single screw main machine for the whole series, it can save more than 15% energy than the secondary dry twin screw and more than 36% energy than the primary twin screw. Oil-free screw air compressor reaches the energy-saving level of oil machine. Avoid frequent and high maintenance of dry screw. Energy saving: Grankering single-screw main engine with high volumetric efficiency is adopted, which has low specific power and is more efficient and energy-saving than twin-screw oil-free air compressors.
Spraying processes are often seen in daily life, such as the surface of vehicle bodies, hardware and rubber products, and the main function is to prevent corrosion. In the painting stage often use screw air compressor to do power device. Then the painting field is on the air compressor.
The application industries of water-lubricated air compressors produced by Shanghai Granklin Group: university laboratories, chromatographic analysis, medical pharmacy, dentistry, food processing, construction engineering, chemical industry, machinery, environmental protection, meteorology, hydropower, spraying, sandblasting, PET Bottle blowing, leak detection, metallurgy, water treatment, printing, shipping, textile, petrochemical, electronics, instrumentation, tobacco, nitrogen production.
Why do you need to change the air compressor oil regularly? 1. Mechanical oil is an aromatic hydrocarbon synthesized by chemical industry, and when the air compressor running at high pressure and high temperature is running back and forth, it will continue to decompose small molecules of cyclic hydrocarbons.
Users who do not know about the air compressor industry will choose brand or well-known equipment in order not to step on the pit. This is why users will ask when purchasing screw air compressors: What brand of screw air compressor is better?
