What is the maintenance method of clean bench
What is the maintenance method of clean benchThe clean bench is a kind of air filtration machine and equipment that provides a local clean and sterile testing working environment, which can artificially control the emission of the gas that has been contaminated in the working area through the professional filtration and safety channel, preventing the adverse effects on the human and natural environments, and it is a kind of safe microbial strains of special type clean bench. Can also be widely used in laboratories, medical services, biomedicine, and other related fields, to improve the standard of processing technology, maintain the health of the operator, improve product quality and output rate have excellent practical results!Maintenance of clean bench: The operating table selects the positive pressure pollution area all surrounded by negative pressure area construction. In the use of formaldehyde fumigation on a clean bench for sterilization treatment before, to avoid formaldehyde leakage, the first to use the "soap bubble" method of the entire equipment for the airtightness of the test. Regular wind speed and wind direction meter to accurately measure the work area wind, such as inconsistent with the provisions of the performance parameters, you can adjust the centrifugal fan power supply system voltage. When the centrifugal fan working voltage is adjusted to a larger, the working area wind is still not on the performance parameters of the regulations, it is necessary to replace the exhaust high-efficiency filters, the replacement of exhaust high-efficiency filters must also be replaced in addition to the exhaust high-efficiency filters. After the end of the replacement, the application of a floating dust particle counter to check the sealing around the edge is not good, if there is a leak use sealant to plug the leak. The centrifugal fan does not need special maintenance, but it is proposed to carry out regular maintenance. When replacing the high-efficiency filter, pay special attention to the following matters, When replacing the high-efficiency filter of exhaust air/exhaust air, the machine should be switched off, and firstly, the clean worktable should be sterilized. When upgrading the high-efficiency filter, it is necessary to maintain the filter paper intact when unpacking, transporting, and installing, and it is strictly prohibited to damage the filter paper by touching it with force. Before installation, flush the new high-efficiency filter to the bright spot, and check with the human eye whether the high-efficiency filter is loopholes due to transport and delivery, etc. If there are loopholes, it can not be applied. Installation should also pay attention to the arrow mark on the high-efficiency filter in the clean bench air inlet orientation to maintain consistency in the twisting of the clamping gongs, the force to be uniform, that is, to ensure that the high-efficiency filter fixation and sealing stability and reliability, but also to prevent high-efficiency filters deformation caused by leakage. |
