A hot summer day, the national appeared in many parts of the hot weather, we all know that the hot weather will work to bring inconvenience to our life.Risk also increases, metaphor is often because of the high temperature lead to electrical appliances electrical short circuit on fire, wash equipment experts shall be with you today in the laundry staff analyse in the hot summer how can we do the safety problem of hotel laundry room, the right to operate the washing equipment?Here we summarized the eight points regarding summer operating washing equipment:
1, insulation resistance.Large washing equipment in damp environment, no electricity can not less than 7 m , the resistance between the parts in the neutral and live more than 2 m .
2, electrical strength.Washing equipment should be able to withstand the experiment voltage 1500 v, in wet under voltage, you should be able to withstand voltage of 1250 v, in one minute of experiments, washing equipment breakdown and flickers won not happen.
3, washing equipment requirements charged on contact resistance between metal and grounding resistance should be less than 0.2 , and washing machines in the ground resistance of less than 0.1 .
4, leakage current.Large washing equipment generally won not appear the leakage phenomenon, generally in the standard condition, washing equipment with the distance between the metal parts and related charged body is less than 8 mm, can leak current is no more than 0.5 MA.
5, startup and operation performance.Motor at rated voltage and rated load can be normal operation, but when the power supply voltage fluctuate by less than 10%, washing equipment operation is not affected.
6, temperature control.Washing equipment is introduced in the standard service condition, the motor winding temperature rise should be less than seventy-five degrees, electromagnet and the rise of temperature of the solenoid valve can not exceed eighty degrees.
7, stability: washing equipment should have enough stability in use at any location on a inclined plane and horizontal plane into 10 degrees, should not turn to the washing machine.
8, automatic power: your offline in dehydration operation, when the user open the laundry cap, the washing machine motor or motor dehydration should be without electricity.
