commercial air curtain Notice what's safe

What are the safety standards to pay attention to when using the commercial air curtain?

What are the safety standards to pay attention to when using the commercial air curtain? Here is a brief introduction of one of the commercial air curtain manufacturers.

1. The safety requirements of the commercial air curtain shall comply with the provisions of zbj72-018.

2. The connection of the commercial air curtain electrical wiring shall be neat, strong, the wire through the hole and the plug shall be insulated pipe or other appropriate protective measures.

3. Commercial air curtain in room temperature, often wet conditions, using the 500 v insulation resistance meter to determine commercial air curtain live part and not charged the insulation resistance between metal parts and continuous operation of the condensate conditions as stipulated in the table 6 after 4 h, 500 v insulation resistance meter is used to test the commercial air curtain with the live part and the live part charged insulation resistance between metal parts inspection, the cold and hot state of insulation resistance shall be not less than 2 m Ω.

4. The electric strength of the air curtain in business the speed of air curtain files were placed in the "on" position, between the live part and the charged metal parts to ac voltage of 1500 v rated frequency. The voltage should not be greater than half of the set value and then quickly up to full value for 1min. In mass production, 1800V voltage and 1s are used instead.

5. The commercial air curtain shall measure the winding temperature of the motor immediately after running 4h continuously according to the specified freezing test condition. Temperature rise is calculated according to GBA755.

6. Commercial air curtain in accordance with the provisions of the condensate test condition and the connection continuous operation of figure 5 4 h, and then to 110% rated voltage, measure the commercial air curtain exposed metal part and the power cord, the leakage current between the leakage current value between the exposed metal part and the power cord should be no greater than 1.5 mA.

For safe use of commercial air curtain, commercial air curtain is required to meet certain safety standards. Only in this way can consumers be relieved. 1. Sterilization of algae

Add bactericidal agents to remove all kinds of bacteria and algae in the water system.

2. Slime stripping

Add the stripping agent to remove the slime from the inner wall of the pipe and clean it out through the circulation.

3. Chemical cleaning

Add chemical cleaning agent and dispersant to remove the rust, scale and oil pollution of the inner wall of the pipe.
