After the air shower room is finished or installed, the air shower room manufacturer or the owner must carry out basic testing to determine whether the air shower room is qualified and can be put into use. The following are some important tests for the air shower room manufacturers. Standard, for air shower users: 1 high-efficiency filter leak detection, after the installation of high-efficiency filter, the leak detection method should be carried out according to the on-site leak detection method provided by (clean room construction and acceptance specifications). 2. The test method for the average wind speed vent speed of the nozzle airflow adopts the method provided by GB8070. The average air velocity of the air shower is the arithmetic mean of the wind speed readings of each measured vent. Airflow average wind speed should After the air shower room is finished or installed, the air shower room manufacturer or the owner must carry out basic testing to determine whether the air shower room is qualified and can be put into use. The following are some important tests for the air shower room manufacturers. Standard, for air shower users reference: 1 High-efficiency filter leak detection, after the installation of high-efficiency filter is completed, the leak detection method should be carried out according to the on-site leak detection method provided by (clean room construction and acceptance specification). 2. The average air velocity of the nozzle airflow The test method of the nozzle wind speed adopts the method provided by GB8070. The average air velocity of the air shower is the arithmetic mean of the wind speed readings of each measured vent. The average air velocity of the airflow shall comply with the requirements of Table 3. 3. Noise The front center of the measured air shower chamber is horizontally 1000mm outward and measured at a height of 1500mm from the ground. The noise value should meet the relevant requirements. 4 illuminance Set a measurement point every 500mm. When the distance from the inner wall is less than 150mm, it is no longer set. The air shower chamber under test is placed under normal working conditions, and each measuring point is detected by an illuminometer at a height of 800 mm from the ground. The illuminance of the measured air shower is the arithmetic mean of the illuminance of each measurement point. 5 differential pressure Install the differential pressure gauge outside the blower, and place the test tube through the sealable hole in the spray chamber 1m above the ground, not less than 20cm from the inner wall. Close the door of the shower room and start the fan of the shower room. The indoor and outdoor pressure difference was measured after 15 seconds. Repeat the measurement three times. 6 leakage current, according to the standard test. The current value should be in accordance with the regulations. 7. Grounding resistance All the function switches of the air purifying chamber to be tested are placed in the “off†position. The resistance value between the grounding terminal and the accessible metal parts is measured by the grounding resistance tester. The resistance value should meet the requirements. 8 withstand voltage The electrical strength test lasted 1 min and was subjected to an AC voltage of a fundamental sine wave with a frequency of 50 Hz. The test was performed between the power input and the metal casing. The initial applied voltage does not exceed half of the specified value and then rises rapidly to the specified value, and no breakdown should occur during the test. The withstand voltage should meet the requirements. 9 insulation resistance Insulation resistance measurement after applying 500V DC voltage for 1min, the value between the live parts and the housing should meet the requirements 10 electronic interlocking should detect the interlock function of the door on both sides of the air shower a) The air shower is not blown. Open the door on the side of the shower chamber arbitrarily and check if the other side door cannot be opened. The door on each side shall be tested at least three times; b) When the air shower is in a blown state. Check that both sides of the door are locked, at least three times; When the air shower is powered off or the door's self-locking function fails, whether the two sides of the door can be manually opened, at least three times. 11 packaging transportation test.
