3. The explosion-proof blower has lower limit requirements for the clearance between impeller and casing. In order to pursue efficiency, fans often have upper limit requirements for clearance, which are contradictory to each other.
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.
1. Objective to ensure the correctness of the air shower room and the safe use of the single air shower room, so as to ensure its service life. 2. Scope: dust free workshop of production department. 3. Operation procedure (1) the personnel entering the clean and dust-free room should take off their coats and remove watches, mobile phones, accessories and other items in the outer room. (2) Then wait for the wind drenched personnel to enter the inner room, and put on clean and dust-free clothes, caps, masks, and gloves of single air shower room, and prepare to enter the air shower room.
Name: the air shower room (also known as air shower room, air shower room, air shower door, air shower room, Airshower equipment, air shower fan, etc.) is the necessary channel for personnel to enter and exit the dust-free room, and it also plays a buffer role in airlock airtight dust-free room. It is an effective equipment for personnel to remove dust and prevent outdoor air pollution in the dust-free room, and it is also an effective equipment for personnel in purification workshop Required equipment for.
(3) after entering the air shower room, the personnel should first close the door and then stand in the induction area. Especially when many people enter together, close the air shower door before starting the air shower. (4) The personnel receiving wind shower in the air shower room shall not deliberately avoid the wind shower nozzle. (5) It is strictly forbidden for any non equipment personnel to adjust or set any technical parameters of the air shower room.
7。 The wind speed of the air nozzle is more than 25m / s, and the wind speed on the human body is more than 18m / s, 8. EVA sealing material with high sealing performance, 9. Imported electronic components, reliable performance, 10. Advanced noise reduction and mute system, 11. Equipped with stainless steel multi angle adjustable nozzle, double volute outer rotor, large air volume and low noise fan, surface wind speed is more than 25m / s, 12. Modular assembly mode, can be assembled into various lengths of shower size according to actual needs.
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.
2. There are requirements for the impeller material and the material of the inner wall of the casing corresponding to the impeller, such as using aluminum wind blade and iron inner wall, or iron wind blade and adding aluminum ring on the inner wall.
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.
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.
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.
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 correctly installed. If the light sensing two sides are opposite and the light sense is normal, it can automatically sense the shower.
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 connected reversely. The manufacturer of the single air shower room has a specially assigned electrician to connect the line when it is installed at the factory. 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, and the serious one will be burnt off It is recommended to use the circuit board of the air shower room. The enterprise should not change the wiring lightly. If it is necessary to move the circuit board, please consult the manufacturer of the air shower room for solution.
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.
The air shower room is composed of cabinet, stainless steel door (steel plate paint door or color steel plate door with window), coarse effect filter, high efficiency filter, fan, static pressure box, nozzle interlock controller, operation panel, induction device, etc. 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. The inner bottom plate is made of stainless steel plate, which is friction resistant and easy to clean. The main materials and dimensions of the box can be customized according to customer requirements.
--- install the double doors of the air shower chamber -- upper roof plate --- pre tighten the box and roof screws --- adjust the horizontal position of the air shower chamber with!
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 usually replaced once in 1-6 months, and the high-efficiency filter in the air shower room is generally replaced once in 6-12 months)!
