Nowadays, there are many markets. How to choose the cooling equipment suitable for your workshop? Optimize the service, advanced equipment, and reach the ventilation equipment Co., Ltd. Tell you what should be paid attention to the cooling equipment in the workshop?
First, distinguish from the outer frame material: FRP glass fiber (glass reinforced plastic), galvanized sheet, plastic steel;
The galvanized sheet negative pressure fan is made of galvanized iron sheet (commonly known as tinplate). The most common negative pressure fan in the market is long. Because it is affordable, many manufacturers choose this type of negative pressure fan; but this negative pressure The fan has a short service life;
Negative pressure fan made of plastic steel: it is rarely used on the market;
FRP glass fiber negative pressure fan: FRP is fiber reinforced plastic
FRP characteristics:
(1) Lightweight and strong.
(2) Good corrosion resistance. It has good resistance to atmospheric, water and general concentrations of acids, bases, salts and various oils and solvents.
(3) Good electrical performance. Excellent insulating material used to make insulators. Good dielectric properties are still protected at high frequencies. The microwave permeability is good.
(4) Good thermal performance. FRP has low thermal conductivity and is not easily deformed.
Due to the above characteristics of FRP, the negative pressure fan of FRP material is resistant to high temperature, acid and alkali, light and stable, and has a long service life;
Second, the transmission mode: the transmission mode of the negative pressure fan is divided into direct type and belt type.
From the perspective of this transmission mode, the transmission mode affects the air volume, noise, and maintenance of the fan;
1. The direct type negative pressure fan blade is directly mounted on the motor, which reduces the power loss caused by the transmission. The fan of the same power, the air volume of the direct negative pressure fan is about 10% larger than that of the belt type; the belt type is negative The pressure fan belt will loosen after a long time, loose
After the move, the fan air volume will drop significantly.
2. There is no noise generated by belt friction in direct mode.
3, the belt type to be maintained, the general fan belt can be used for two years (imported) a small amount can only be used for the previous year, especially the replacement of the negative pressure fan installed in the high air is also more difficult.
4. Motor: The motor is the heart of the negative pressure fan. Belt type motor General type of ordinary motor (except for individual manufacturers matching special motor, force ventilation has its own special motor for negative pressure fan); while direct type motor is dedicated for negative pressure fan 12 pole
Aluminum shell motor with dustproof rating above IP55;
5. Wind blade: The blades of the negative pressure fan are divided into: aluminum alloy, stainless steel, aluminum alloy sanding, aluminum-magnesium alloy die-casting, nylon and iron, etc. The difference of wind blade material is determined according to the place of use. Commonly used blades are aluminum alloy, stainless
Steel and aluminum alloy sanding blades. The aluminum-magnesium alloy die-casting blades have high temperature resistance and are relatively stable and not easily deformed and broken due to the characteristics of the material; nylon and iron blades are used in acid-base places, and are usually corrosive in electroplating plants.

Special Rock Wool Board For Curtain Wall
Special Rock Wool Board For Curtain Wallis an inorganic fiber board made of basalt as the main raw material through high temperature melting processing. It was successfully tested in June, 1981. Rock wool board is a new type of thermal insulation, flame-proof and sound-absorbing material.
The artificial inorganic fiber made of rock wool board by high temperature melting process has the characteristics of light weight, small thermal conductivity, heat absorption and incombustibility. The initial development is a common type of application in construction, which is mostly used in industrial buildings. It should meet the requirements of "Application Types and Basic Requirements of Building Thermal Insulation Materials". Rock wool is a kind of external insulation material. When the market share of 90% of the organic thermal insulation materials is stagnant, rock wool, as an inorganic thermal insulation material for exterior wall, has ushered in an unprecedented market opportunity.
