1. Load-bearing capacity, vibration and noise requirements of the plant

The bearing capacity of the plant floor should be greater than 8KN/m2

Vibration should be controlled within 70dB, and the maximum value should not exceed 80dB

Noise should be controlled within 70dBA.

 

2. Power supply

Generally, single-phase AC 220 (220±10%, 0/60Hz) and three-phase AC 380 (380±10%, 50/60Hz) are required, and the power of the power supply should be more than double the power consumption.

 

3. Air source

Configure the pressure of the air source according to the requirements of the equipment. The air source of the factory can be used, or an oil-free compressed air machine can be configured separately. The general pressure is greater than 7kg/cm2. Clean, dry and purified air is required, so it is necessary to degrease, dedust, and dewater the compressed air. Use stainless steel or pressure-resistant plastic pipes as air ducts.

 

4. Exhaust

Reflow soldering and wave soldering equipment need to be equipped with exhaust fans. For all hot blast stoves, the minimum flow rate of the exhaust duct is 500 cubic feet per minute (14.15m3/min)

 

5. Lighting

The ideal illuminance in the workshop is 800~1200LUX, at least not less than 300LUX. When the illuminance is low, local lighting should be installed in the inspection, repair, measurement and other working areas.

 

6. Working environment

Keep the workshop clean, free of dust and corrosive gases. The production workshop should have cleanliness control, and the cleanliness is controlled at: 500,000 grades.

The ambient temperature of the production workshop is 23±3°C, generally 17-28°C, and the relative humidity is 45%-70%RH.

Set up a suitable temperature and humidity meter according to the size of the workshop, conduct regular monitoring, and be equipped with facilities for adjusting temperature and humidity.
