Plant Hydropower System Layout Design
The upper water pipe of the laboratory is made of DC15PP material, PVC material, Kaitai pipe, etc., the water pressure is not less than 2.5MPa, the lower water pipe is made of DC50PP material, ceramic, PVC material, etc., the minimum slope is not less than 5°, the sewer pipe is set to U The material of the upper and lower water pipes should not be made of metal; the sewer pipes should be designed with independent circuits, and should not be connected with other sewers such as toilets; Cut off the supply of the water tank to avoid direct connection with the indoor water network; in order to prevent backflow, check valves are installed on the water supply pipe of the laboratory system and near the faucet, and a water level alarm must be installed on the high temperature water tank. Water; hand-washing devices should be set up at the exit, with non-manual switches, and eye-washing devices should be set up in biosafety labs two to four. Eyewash devices are installed, and high-pressure flushing water guns should be provided for large animal laboratories; the pre-embedded points of the water supply and sewer pipelines of the washing pool sink are arranged on the ground, facing the middle of the table and 350mm away from the table and the wall. The specification of the upper water pipe is Φ21mm, 180mm above the ground, with a control water valve, and the specification of the down pipe is Φ50mm, 100mm above the ground.
The drainage system of the general area and the polluted area should be separated. In the pharma machinery, especially the fourth-level laboratory, the drainage system for high temperature sterilization at 120°C for 30 minutes and the drainage system for chlorine sterilization should also be separated; Except for shower rooms, animal rooms, dissection rooms, and corridors where large animals stay, no floor drains shall be set up in the Class-I laboratory. The drainage from the protection areas of Class-III and Class-IV laboratories shall be collected through special pipes and sent to independent devices for sterilization; ventilation The pre-embedded points of the water supply and water pipes of the sink in the washing pool of the cabinet are arranged at a distance of 100mm from the wall on the back of the fume hood and 250mm from the right side of the cabinet; the specification of the water supply pipe is Φ21mm, 180mm above the ground, with a control water valve, The size of the sewer pipe is Φ50mm, and it is 100mm above the ground; the pre-embedded points of the water supply and sewer pipelines of the corner cabinet pool are arranged on the ground, facing the countertop and leaving the countertop and the center of the wall at a distance of 450mm from the two right-angle sides. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for laboratories and GMP laboratories.
Reasonably design laboratory circuits, use copper core BVR and BV for wiring layout, wire diameter and switch size are calculated according to the power consumption; separate circuits for large-load electrical appliances, and design corresponding automatic protection switches; sockets, electrical appliances The shell should be well grounded to ensure personal safety; the power supply of instruments and precision instruments should be equipped with an AC voltage stabilizer or an isolated power supply to ensure safe and reliable operation of the instrument; the illumination of the biosafety clean room should be higher than that of the general clean room, and waterproof sockets should be used. and lamps, which are to be replaced in the technical mezzanine outside the room
, emergency lighting of no less than 30min should be set up; air conditioners, lighting, and electric heating devices should be reasonably designed to achieve safe and reliable use; for side tables with a size exceeding 3000mm, a set of 1000mm long specifications should be reserved at intervals of 3000mm. It is a 4mm2 single-phase 220V AC power cord, which is used on a wall 500mm above the ground for equipment, wire troughs or reagent racks on the table; for side tables with a specification of less than 3000mm, only one set of 1000mm long is reserved. 4mm2 single-phase 220V AC power cord, on the wall 500mm above the ground, for table top equipment, wire troughs or reagent racks. The power supply of the computer table, instrument table, sky platform and microscope table is arranged on the wall with a height of 500mm from the ground in the middle of the wall facing the table, and a set of 1000mm long single-phase 220V AC power cords with a specification of 4mm2 are reserved; The power sockets of gas cylinder cabinets and ultra-clean benches are single-phase 220V AC, and they are arranged at a height of 1200mm from the ground and 100-200mm from the side of the cabinet. They are all wall-mounted recessed sockets; other cabinets that require power supply or The power sockets of the equipment are single-phase 220V AC or three-phase 380V AC, and are arranged at a height of 1200mm from the ground and 100-200mm from the side of the cabinet. They are all wall-mounted recessed sockets.
