Basic Principles Of Layout Of Hydropower Plans In The Planning And Design Of Laboratory Bench
May 22, 2018

When the experimental bench manufacturer plans the design of the experimental bench for the customer, it is necessary to indicate the location of the power supply in the laboratory and the embedded position of the upper and lower water and the distance between the upper and lower water pipes from the floor. The parameters of the hydropower system provided by the customer and the size of the room are required. The layout of the styles and test benches is designed to produce professional qualified hydropower diagrams, and then the customer designates the places marked by the design of the hydropower layouts provided by us and reserves the power supply, power outlet, water supply pipeline and sewage pipeline that meet the specifications. can. When the time comes, the test bench installer will only need to follow the drawings. The benefits of this will not only be convenient and convenient, but also because the hydropower system and experimental stations are the result of the preliminary overall planning, so they are more scientific and safe.

As an experimental station manufacturer, the following principles must be taken into account when carrying out experimental hydropower station planning and design.

Power supply wiring principle of the test bench

For side benches up to 3000mm in size, only one set of 1000mm long single-phase 220V AC power cords (three wire system: L FireWire, N Neutral wire, E Ground wire) with a size of 1000mm long is reserved. 500mm high wall; for use on equipments, benches or racks for test benches;

For side table with specifications over 3000mm, one set of 1000mm long single-phase 220V AC power cords (three wire system: L FireWire, N Neutral wire, E Ground wire) with a length of 1000mm is reserved for every 3000mm arrangement. 500mm high on the ground; for use on equipment, wiring ducts or reagent racks on test bench surfaces;

Power supply wiring principles for the central laboratory bench and reagent rack:

The central laboratory bench within the specification of 3400mm shall be arranged at a distance of 300mm from either end of the central benchtop, and only one set of 1000mm long single-phase 220V AC power cords with a size of 4mm 2 shall be arranged (three wire system: L FireWire, N The zero line and E ground line shall be used on the ground for the use of reagent racks, equipment or wire troughs on the bench top.

Central test benches with specifications over 3,400mm and above, at the ends of 300mm from the middle of the end, each set is reserved with a set of 1000mm long single-phase 220V AC power cords with a size of 4mm2 (three wire system: L FireWire, NZero Lines, E-ground) out of the ground, for use on reagent racks, equipment, or wire troughs on benchtops.

The pre-embedment points of the upper and lower water pipelines of the central laboratory bench shall be arranged below the sinkholes facing the water tank. The specific dimensions shall be marked according to the requirements of the actual room position of the central laboratory bench; the upper water pipe shall be φ21mm, 180mm above the ground, with control Water valve; downpipe specification is φ50mm, 100mm above the ground.

Arrangement principles for the upper and lower water pipes of the washing tank, the corner tank, and the sink

The pre-embedded points for the upper and lower pipelines of the sink sink are arranged on the ground, and are located at a distance of 350 mm from the wall of the lab bench in the middle of the bench top. The upper water pipe specification is φ21mm, which is 180mm above the ground, and it has a control water valve. The downpipe specification is φ50mm, 100mm above the ground.

The pre-embedded points of the upper and lower pipelines of the corner tank are arranged on the ground, and are directly opposite to the central position of the experimental table surface at a distance of 450mm from the two right-angle sides of the experimental tabletop. The upper water pipe specification is φ21mm, which is 180mm above the ground, and it has a control water valve. The downpipe specification is φ50mm, 100mm above the ground.

The power supply layout principles for cylinder cabinets, medicine cabinets, clean benches, and other cabinets that require power supply:

The power sockets for the gas cylinder cabinets, medicine cabinets (with exhaust air) and clean test benches are single-phase 220 volt AC and are arranged at a height of 1200 mm from the floor and 100 mm to 200 mm from the sides of the cabinet, both of which are two positions ( Flat plug, three plug) wall concealed concealed socket.

Other power supply cabinets or equipment whose power sockets are single-phase 220 V AC or three-phase 380 V AC (special requirements) are arranged 1200 mm above the floor and 100 mm to 200 mm away from the cabinet, all of which are wall-embedded dark. Install the socket.

Power supply wiring principles for computer stations, instrument stations, day platforms, and microslabs:

Electrical power supplies for computer desks, instrument desks, sky platforms, and micro-slabs are arranged on a wall 500 mm above the ground in the center of the countertop and a set of 1000 mm long single phase 220 V AC with a size of 4 mm 2 is reserved. Power line head (three wire system: L FireWire, N Neutral, E Ground);

The pre-embedded points of the upper and lower pipelines in the sink tank of the fume hood shall be located 100mm from the back of the fume hood and 250mm from the right side of the cabinet; the upper water pipe shall be φ21mm, 180mm above the ground, with control water Valve; Sewer pipe size is φ50mm, 100mm above ground.
