When the laboratory uses compressed air, it needs high-quality oil-free air. The "water-lubricated oil-free air compressor" produced by "Shanghai Grankering Group" can provide 100% oil-free "oil-free compressed air" for high-precision tests ".
In the laboratory ventilation equipment we can refer to the following:
basic concepts of 1. laboratory ventilation
the concept of ventilation and fume hood: The so-called ventilation is to add fresh air to the outdoor air directly or after purification, so as to maintain indoor air conditions, to maintain health standards and meet the requirements of the production process, we call the former exhaust, the latter is called air supply. The fume hood can be simply understood as a box and a fan, and the gas generated in the box is discharged by the fan and is safely discharged into the atmosphere.
2. Classification of ventilation: According to different power, ventilation system can be divided into natural ventilation and mechanical ventilation. Mechanical ventilation can be divided into comprehensive ventilation and local ventilation. Comprehensive ventilation refers to a way of ventilation in the whole room. Local ventilation refers to the ventilation mode in which the scope of ventilation is controlled in the place where harmful substances are relatively concentrated, or the ventilation mode in local areas where workers often move, for example, fume hoods, universal exhaust hoods, atomic absorption hoods, etc.
Construction composition of 2. laboratory ventilation system
laboratory ventilation system is generally composed of air supply system and exhaust system, including air supply/exhaust equipment, air supply/exhaust pipe system (including air supply/exhaust control equipment, etc.), muffler, filtering equipment, possible isolation protection equipment, fan, control system, etc.
3. Laboratory Ventilation System: Classification and Selection of Fans
1. Classification of fans: According to the air flow mode, fans are divided into three types: centrifugal (often placed outside the house), axial flow (often placed in the house) and mixed flow (oblique flow). According to the material classification, fans mainly include ordinary steel fans, stainless steel fans, PVC fans and glass fiber reinforced plastic fans.
2. ① The characteristics of axial flow fans are: low power consumption, low operating cost, but high noise, low fan pumping force (low wind pressure), suitable for simple systems, generally installed on the wall or pipeline; ② The characteristics of centrifugal fans are: high power consumption, high operating cost, high noise, large fan pumping force (high wind pressure), suitable for complex systems, mainly installed outdoors or on the roof; the characteristics of the diagonal flow fan are: power consumption, operating costs, fan suction between the first two, the noise is small, suitable for simple systems, generally installed in the room.
As we all know, air compressors account for more than 70% of the industrial electricity consumption, which belongs to the "big tiger" in industrial electricity consumption ". With the rapid improvement of the national economy, as an important part of the general machinery industry-compressor
Water-lubricated air compressor, oil-free air compressor produced by Shanghai Granklin Group, focuses on energy-saving frequency conversion series for enterprises to save energy and provide stable oil-free clean compressed air. What are the advantages of oil free air compressor?
Granklin's oil-free air compressor covers the low-pressure and medium-pressure series. Water lubricated air compressor products from 0.2 Mpa-4Mpa pressure, power to see the motor power. Granklin oil-free air compressor models are divided according to motor power, and air-cooled or water-cooled.
View detailsCommon types of oil-free compressor are: oil-free scroll air compressor, dry oil-free air compressor, water lubrication oil-free air compressor. Different oil-free screw air compressor models, exhaust pressure, power and exhaust volume parameters are different. The medical water-lubricated air compressor produced by Shanghai Granklin Group is 100% oil-free.
View detailsIf you determine the size and type of compressor, but there is a problem is the choice of oil lubrication or oil-free air compressor. Your choice on this issue should be based on the compressed air application process. Do I need an oil-free compressor? Choose
The gas supply pressure required by the glass industry is relatively small. If the conventional air compressor on the market is used, it will cause a waste of resources. The conventional pressure on the market is 0.7-1.0mpa, and the glass industry is 0.3-0.5mpa. This requires accurate selection during selection without wasting too much energy consumption. When your air pressure is 0.2 -- 0
Air compressor is not only the basic product of modern industrial development, but also a kind of all-pneumatic equipment. Shanghai granklin Group Co., Ltd. is a production-oriented entity enterprise integrating production, development and sales. it is a professional manufacturer of water-lubricated oil-free air compressors in China.
How to properly maintain and maintain oil-free air compressor 1, oil-free air compressor intake air filter element maintenance and maintenance. The air filter is a component that filters out air dust and dirt, and the filtered clean air enters the compression cavity of the screw rotor for compression. Because of the screw machine
(1) To fully meet the gas consumption of gas equipment, the maximum gas consumption should be calculated according to the type and quantity of pneumatic equipment, and the gas consumption that may be increased in the future should be included, and then the air compressor that can meet the gas supply requirements of pneumatic equipment should be selected.
Now it has entered the summer that people love and hate, and the temperature in many places has risen to above 30°C. In the face of the hot summer, screw air compressor temperature is too high by what reason? Summer, screw air compressor is more common fault is scattered
