Medical equipment clean room design and construction and analysis of the problems of!
There is no complete design drawing this is a common problem. Complete clean workshop design drawings shall include at least the process flow layout; Back to the air duct, tuyere layout; Air conditioning system diagram; Electric lighting diagram; Process water gas arrangement. Found that more than 70% of the enterprises in the test, no complete plant design, some even just process flow diagram with hand-painted sketch. Drawing a lack of will to clean room in the future operation and management, system maintenance and possible reconstruction brings many problems in the future.
The function of the function of clean room and clean room layout and layout should be according to the characteristics of the product and process requirements to determine. Medical device sort is more, different products need clean room is also different, such as injection molding, extrusion workshop need larger area, height is higher, at the same time to consider exhaust problem. But no matter how easy it is to the size of the product, from clean workshop on the whole, the general function is indispensable, such as two more, buffer, clean, clean rooms, laundry room, corridor cleaning deposit, etc., between the auxiliary function room can better guarantee the normal operation of the main preparation. And there are plenty of imperfect auxiliary function room, some design no clean clothes cleaning deposit or sanitary ware; Some of the design and production process, such as a welding procedure preparation did not set the exhaust, etc. Except necessary function between, between other auxiliary production should be in clean zone, such as individual enterprises are designed to clean zone between the water making, this is wrong, on the one hand equipment is one of the "dust source"; On the other hand make purification area expands, wasting energy, increase the cost. Equipment cleaning, clean clothes washing, clean is provided to consider such as drainage, the design of the floor drain is very important, if the design is bad will become a pollution source.
The applicability of the purification system does not accord with production and energy saving requirements in determining the level of purification of clean room, the designers should know the categories and characteristics of products based on the principle of "standard", "energy saving", according to different products of different YY0033-2000 appendix purification level requirements for design, including the form back to the wind, the selection of the fan air volume and air conditioning unit wattage rating, etc., at the same time, according to the technological requirements to determine the corresponding purification area. Based on the analysis of project investment, clean for each extending outward one meter high, wide engineering cost will be increased by 20%; Other air conditioning investment accounted for 30% of total investment, clean room for each level of purification, improve air conditioning purification investment costs will increase by 35%, operation cost will be increased by more than 40%, which means that the cost of production will also be synchronous growth.
