How to ensure the normal operation of the cleanliness testing equipment?
The cleanliness testing equipment is a handy hand-held instrument for measuring the cleanliness of part surfaces. It integrates pressure jet cleaning, online filtering and recycling of cleaning agents, and circulating fine filtering, so that the part cleaning and particulate pollutants filtering and recycling can be carried out simultaneously. The particulate pollutants on the surface of parts can be collected to the surface of the filter membrane in a timely manner. After the cleaning of parts by the cleanliness testing equipment, the filter membrane samples can be obtained, Reduce the retention time of particulate pollutants in cleaning agent; It subverts the traditional manual cleaning and detection method, and the cleanliness detection equipment standardizes the cleanliness detection and control process to improve the detection efficiency.
Pay attention to the method when operating the cleanliness testing equipment and the maintenance after use. The specific precautions are as follows:
1. When the inlet pipe of the cleanliness testing equipment is covered or blocked, do not start the counter.
2. It should be used in a clean environment to prevent damage to the laser sensor.
3. It is prohibited to extract the gas containing oil stain and corrosive substances, and do not measure the mixed gas (such as hydrogen and oxygen) that may react. These gases may also explode in the counter. To measure these gases, it is necessary to contact the manufacturer of the cleanliness testing equipment for more information.
4. Do not sample compressed air without high-pressure decompression equipment (such as high-pressure diffuser). All counters are designed to operate at one atmospheric pressure. The working position and sampling port of the cleanliness testing equipment shall be in the same air pressure and temperature and humidity environment to ensure the normal operation of the cleanliness testing equipment.
5. No water, solution or other liquid can enter the sensor from the inlet pipe.
6. The particle counter is mainly used to test the clean environment of the purification workshop. When there are loose particle materials, dust sources and spray in the measured area, it should be kept at least 12 inches away from the inlet pipe. To prevent the above particles and liquids from polluting the sensor and pipeline.
7. During sampling, avoid sampling the gas polluted by the gas discharged from the counter itself.
8. When connecting an external printer or an external temperature and humidity sensor, turn off the counter first; When printing, there must be printing paper on the printer, otherwise the print head will be damaged.
9. When carrying the cleanliness testing equipment, the equipment shall be handled with care and be less subject to vibration and impact. Especially for the desktop particle counter, more care should be taken to avoid damaging the internal components.
The above are the details that should be paid attention to when operating the cleanliness testing equipment. Only standardized operation can make the equipment effective, so special attention should be paid to when using it.
