○ AC220/380V three-phase four wire + protection ground wire; ○ Voltage fluctuation range: AC220/380V + 10% ○ Frequency range: 50Hz + 0.5 Hz ○ Ground resistance is less than 4; TN-S mode power supply or TT mode power supply ○ The ground wire is used alone and not shared with other equipment. |
○ The use of ambient temperature 5 to 35 DEG C, the best use temperature: 15 to 25 DEG C, relative humidity: atmospheric pressure: 86-106Kpa = 85%RH |
○ Ground level, well ventilated, non flammable, explosive, corrosive gas and dust. ○ There is no strong airflow around, when the ambient air is forced to flow, the air flow should not be blown directly into the box. ○ No electromagnetic field near, without direct sunlight, other thermal radiation source ○Proper maintenance space is left around the equipment. ○ Ground bearing requirements of more than 600kg/ square meters (the upstairs venue) ○ Venue: drainage test box near the best can have faucet and floor drain |
Maintenance considerations and methods:
1 cooling units of the radiator (condenser) should be regular maintenance, keep clean. Dust sticky condenser will make the high-pressure compressor switch jump off and produce false alarms, the condenser should be monthly maintenance, condenser cooling network on chip attachment of the dust suction or boot using hard the hair brush or with high pressure gas mouth blown clean of dust with a vacuum cleaner.
The 2 door or take the test from the furnace, not let the goods on the door to prevent the contact edge glue, glue edge damage and shorten the life.
3 around the body and at the bottom of the ground should be kept clean, so as to avoid a large number of dust suction unit to produce an accident and reduce performance.
Please notice the factory or direct handling of 4. Refrigeration system is the core of this machine, please a year inspection of all brass of any leakage of snow, the horn joint, welding mouth, such as the leakage of grease.
5. Distribution disc large current contact, power distribution room of every year at least clean maintenance more than once, the loose contact will make the equipment in hazardous work state, light burned out component, fire, alarm, personal injury is very dangerous. When cleaning cleaning using a vacuum cleaner will indoor dust suction can be among.
6. The humidifier and water disc regular cleaning, so as not to produce scale, effect of vapour emission, a general finish cleaning a test, the scale has been excluded in a timely manner favorable humidifying tube life and ensure smooth flow cleaning when using copper brush wash rinse clean.
. dry and wet ball of yarn sets of frequently check, after test cloth surface is not clean or harden, or in finishing temperature control, continue to do temperature and humidity control of the ball must be replaced yarn test set, or in more than 85 DEG C high temperature control, go on to the temperature and humidity control. The examination such as non absorbent, please replace the, related to humidity testing accuracy and testing yarn set general March a replacement, replacement application cleaning cloth wiping microthermometry, replacement of new test yarn set should first wash the tank clean
8 the examination and adjustment of the water level of the wet bulb
The water level of the water drum can not be too high, too high to cause the water to overflow the water drum or too low to cause the wet ball to test the yarn sleeve, which affects the accuracy of the wet ball. The water level is about six minutes. The adjustment of the water drum level can adjust the height of the water box [adjusting both sides of the screw]
9. The distribution box two over temperature protection device setting value, please do not just debugging, factory tuned, the protective switch is protection of heating pipe and a humidification tube air burning and water shortage alarm. Set point = temperature set point + 20 DEG to 30 DEG C, temperature test box rose to super thermostat set point, heater power supply is stopped, over heat] over temperature warning lights but the fan is running, if long time operation and supervision, running before do not have to check over temperature protection device is properly set up.
10 inspection and maintenance of waterways
Water pipe is easy to block leakage device, please be sure to check there is no leakage plugging water phenomenon, please promptly eliminate or inform us if there is. In the humidifier water storage monthly replacement to ensure clean water, the water flow is smooth.
11 condenser dust removal
The condenser should be maintained at regular intervals, using the vacuum cleaner to remove the dust from the condenser heat sink or the use of high pressure air.
12 when the test product time to get the product, must be in the shutdown state and the staff must wear a good dry, electricity, temperature resistant gloves to take place the product.
External cleaning and maintenance machine in 13 cases should be removed before operation.
The power distribution room is cleaned at least once or more every year, and can be used for cleaning the indoor dust. The exterior of the box must be cleaned more than once per year, which can be cleaned with soap and water.
