3. If the fan in the air shower room is reversed or the wind speed in the air shower room is very small, please check whether the 380V three-phase four wire circuit is reversed. Generally, the manufacturer of the air shower room will have a specially assigned electrician to connect the line. If the line source of the air shower room is reversed, the light one will cause the fan of the air shower room not work or the wind speed of the air shower room will be reduced, or the circuit board of the whole air shower room will be burned in the heavy case It is suggested that the enterprise using the air shower should not change the wiring lightly. If it is necessary to move it due to production needs, please consult the manufacturer of the air shower room for solution.
If the material of the impeller and the inner wall of the impeller are required to be made of aluminum and iron, the inner wall of the impeller should not be touched by iron and iron. There is a lower limit requirement for the clearance between impeller and casing of explosion-proof blower. In order to pursue efficiency, fans often have upper limit requirements for clearance, which are contradictory to each other. Double blow shower room gauge
4. In addition to the above three points, it is necessary to check whether the emergency stop key inside the air shower chamber is pressed. If the emergency stop key is colored, the air shower will not blow; if you need to press the emergency stop key again, it can work normally.
The air-conditioner can carry more bacteria than 1500-200 m3 / h, which may affect the safety of the air-conditioner. The solution lies in the use of high efficiency air filters. The protection of people's health is one of the most important concerns all over the world. Food production is one of the key areas. It is strictly required that production facilities must effectively avoid any potential pollution risks.
The air shower room is a special passage for the staff to enter and leave the clean area, which can effectively remove the dust on the surface of people and objects and reduce the amount of dust brought into the clean room. At the same time, it has the function of airlock to prevent the invasion of unclean air. To cooperate with the clean air conditioning system to ensure the cleanliness of the clean room.
--- install the double doors of the air shower chamber -- upper roof plate --- pre tighten the screws of the box and the top plate --- adjust the horizontal position of the air shower chamber and fix the connecting screws --- connect the air shower line --- install the air shower!
Fix the position of the air shower chamber --- place the box body of the air shower room --- pre tighten the screws on the box body and the bottom of the air shower chamber.
As the use in the explosive industry and the selection of volatile goods, the enterprise must consider the characteristics and safety of the products produced in the customer workshop when designing the explosion-proof air shower room. All the accessories of the explosion-proof air shower room use electrical appliances and lines with explosion-proof function, so as to avoid explosion caused by contact between flammable gas and equipment in customer workshop. Blow up.
Explosion proof air shower room is widely used in enterprises that need high cleanliness to produce inflammable and explosive materials, such as weapon manufacturers and military. Industrial enterprises, aerospace and other industries.
1. The 380V three-phase four wire power supply is installed in the installation site of the air shower room, and the power supply power is greater than that of the air shower room.
It is composed of stainless steel plate, air filter, air shower door, air door, door and so on. Its bottom plate is made of steel plate bending and welding, and is attached with baking paint processing reinforcing rib, and the surface is made of stainless steel. The cabinet is made of high-quality cold-rolled steel plate, and the surface is treated by electrostatic spraying or baking paint. It is beautiful and elegant. It is made of stainless steel plate with a single inner bottom plate, which is friction resistant and easy to clean. The main materials and dimensions of air shower box can be customized according to customer requirements.
5. When the air shower room can not automatically sense the shower, please check the light sensing system at the lower right corner of the box in the air shower room to see if the light sensing device is installed correctly. If both sides of the light sense are opposite and the light sense is normal, it can automatically sense the shower.
2. When the fan in the air shower room is not working. When the air shower does not work, time to check whether the emergency switch of the outdoor air shower box is cut off. If it is confirmed that the emergency switch is cut off, gently press it with your hand, rotate it to the right and release it.
(3) laminar flow: displacement principle, vertical flow section wind speed: V; horizontal flow section wind speed: v. (1) Centralized air supply: the air handling equipment and fans are centrally set in the air conditioning room, and the high-efficiency filter is arranged at the end. (2) Distributed air supply: generally used in air-conditioning environment or low-level purification environment.
4. On the external boxes on both sides of the air shower room (the power switch here can prevent power cut-off in case of emergency and effectively improve the personal safety of the staff). When the power indicator is not working, it is not necessary to recheck the power supply of the above four air shower chambers.
Before the design of clean room air conditioning system, the original design data that need to be clarified are: meteorological data of outdoor atmosphere and dust concentration of outdoor atmosphere in construction area; design parameters of clean room; production process data (heat and humidity production of production equipment; exhaust air volume; variety, nature, concentration and emission of harmful substances discharged); original building data; required cold The nature of source, heat source and power source.
The air shower / cargo shower room is a special passage for the staff to enter and exit the clean area, which can effectively remove the dust on the surface of people and objects and reduce the amount of dust brought into the clean room. At the same time, it has the function of airlock to prevent the invasion of unclean air. To cooperate with the clean air conditioning system to ensure the cleanliness of the clean room.
Our FFU fans are imported from Germany. Most of the FFU used in dust-free workshops in the market use the "external rotor rear drive type". Compared with the traditional "inner rotor forward tilting type", the FFU has the advantages of compact structure, high efficiency, long service life, high static pressure and low noise. The AC motor used by FFU is also AC motor.
6. When the wind speed of the air shower room is very low for a period of time, please check whether the primary and high-efficiency filters of the air shower room have accumulated too much dust. If so, please replace the filter. (the primary filter in the air shower room is generally replaced once within 1-6 months, and the high-efficiency filter in the air shower room is generally replaced once in 6-12 months).
