Acceptance method of air shower room

Acceptance method of air shower room acceptance method of air shower room: 1 General requirements 1.1 test environment performance test shall be conducted in the laboratory meeting the following environmental requirements: a) temperature: 5 ℃ ~ 35 ℃; b) relative humidity: 35% ~ 85% 1.2 power supply 1.2.1 power supply voltage deviation: 10% of rated voltage; 1.2.2 power supply frequency deviation: ± 2Hz (based on rated frequency) 2 Test instrument (circuit board of air shower room) 2.1 the test instrument shall be sent to the qualified measuring and testing institution for verification on a regular basis The test instrument can only be put into use after verification and calibration, and can be used within the specified validity period 2.2 the following instruments are required for the test: a) particle counter (particle size resolution starts from 0.3 μ m); b) hot ball anemometer with measurement error of ≤± 3% of full scale; c) sound level meter with measurement range of 40 dB (a) ~ 100dB (a); d) illuminance meter with measurement range of 0 LX ~ 1000lx; E) leakage current meter; F) ground resistance tester; g) Withstand voltage tester, output 50Hz, basic sine wave 1500V voltage, and duration can be set within 1s-60s 3 Appearance requirements: visual inspection 4 Precautions for use of the wind shower room of the ultraviolet germicidal lamp: the ultraviolet germicidal lamp actually belongs to a low-pressure mercury lamp The low-pressure mercury lamp uses the lower vapor pressure of mercury to excite and emit ultraviolet light There are two main emission lines: one is the wavelength of 253.7nm; the other is the wavelength of 185nm, both of which are invisible to the naked eye Because ultraviolet light can kill cells, we should pay attention not to directly irradiate human skin, especially eyes Do not look directly at the lamp tube when the UV sterilization lamp is on, because the short wave UV does not pass through the ordinary glass, wearing glasses can avoid eye injury The infrared automatic induction air shower refers to that after the infrared sensor is cut off from the light sense at the other end, the whole intelligent circuit board system detects that the person standing in the induction area will automatically start all devices, so as to achieve automatic air shower Therefore, it is not suitable to turn on the UV germicidal lamp for a long time when using the UV germicidal lamp in the air shower room It is set to turn on the UV germicidal lamp with the inching switch to protect the operator and reduce human injury
