Six common reasons for not blowing of air shower booth

The factory that uses the air shower sometimes will encounter the air shower room does not blow the phenomenon. When the air shower manufacturer fails to arrive in time to deal with the trouble on the spot, may refer to the following note to check the reason of air shower not blow:

1. First check whether the power supply switch and the emergency stop switch are on, if both reasons are not, check the circuit, whether the leakage switch is closed.

2. Whether the IC circuit board is configured to fuse the FUSE safety pipe, and if the fuse fuse is broken, the 4A should be replaced.

3. Check whether the fretting and optoelectronic switches are active, and if not, replace the fretting and optoelectronic switches.

4. If the AC contactor does not work, it will affect the blowing, need to replace the AC contactor.

5. If the circuit board can not output signal to AC contactor coil, it needs to replace IC circuit board.

6. No forced opening is allowed when the shower room is blowing. In case of emergency, stop by emergency switch.

How can the air speed detected in the air shower room?

How can the air speed detected in the air shower room?

Many users are installing air shower room, do not know how to detect the wind speed of the air shower room. The most important performance item of the air shower is wind speed detection, which is the most important aspect.

There are no relevant design codes in the air shower room. The whole industry is relatively confusing. The major manufacturers are in their own affairs. The relevant departments are planning the uniform specification of the air shower room. It is estimated that the QS certification will not come out in the near future.

The problem of wind speed measurement in the air shower room is also the same as the general duct velocity measurement. The difference is that you are measuring far away from the nozzle location. For the wind shower room, it is better to calculate the wind speed by blowing the position to the human body.

Some manufacturers product quality defects, resulting in long-term use of wind leaching room is reduced, not up to clean the purpose of staff, we suggest that wind anemometer tool users can use the professional, the wind speed is very low (less than 18M/S) that cannot be used for manufacturers claim.
