Outdoor Rain Spray Shower Testing Room For Bus Passenger Car Road Vehicle

Bus Passenger Car Road Vehicle Outdoor Rain Spray Shower Testing Room

System Purpose

Mainly meet the standard QC/T 476-2007 "Rainproof Sealing Limits and Test Methods for Passenger Cars", and adapt to the standard GB 29753-2013 “Safety Requirements and Test Methods for Refrigerated Vehicles for Road Transport of Food and Biological Products”.

It is used to inpsect whether the assembly of the body, doors, windows and sunroof is normal, whether the sealing performance is reliable, and whether the installation method is correct

Technical Parameters

1. Equipment function: used for the rain test of passenger cars. The external dimensions of the applicable vehicle range from 3500×1400×1400mm to 13700×2600×4200mm.

2. Rain intensity: the average of the front is 7~12±1mm/min, and the average of both sides, upper, lower and rear is 7~8±1mm/min. The rain intensity of each part can be adjusted.

3. Power supply: AC three-phase five-wire 380V±5% 50Hz or match client's local three phase power supply requirements.

4. Nozzle injection pressure: 150kPa±10kPa

5. Pressure gauge: install a pressure gauge at the outlet of the water pump, pressure: 0~0.5MPa.

6. Flowmeter: Install a total electromagnetic flowmeter after the self-flushing filter at the outlet of the water pump. The total flow rate is 0-150m3/h. The branch pipe adopts a visual flowmeter and is installed after the flow regulating valve.

7, rain time: 1 ~ 60min.

8. Outline dimensions of the frame of the rain detection room (length × width × height): approx.20000×5200×6000mm.

9. The rain detection room is an outdoor skeleton type, without a roof and surrounding protective panels. The frame reserves the interface and space for building a canopy in the future.

Control System

Rain shower devices mainly include: water pump, automatic pressure regulating valve, water pressure gauge (or water pressure sensor), main pipeline, branch pipeline, branch pipeline, flow meter (or flow sensor), flow regulating valve, nozzle, nozzle pipe holder, Pipe rack moving system and electric control system etc. The water supply pressure setting of the water pump needs to ensure that the water outlet pressure of the nozzle is 150kPa±10kPa. The quantity, lift, flow rate and pipeline diameter of the water pump shall meet the requirements of the system. Each spraying surface shall cover the car with the largest external dimensions involved in the rain test and each inspected part of each car. The front and middle raining surfaces shall be movable to adapt to changes in vehicle shape and size.

The rain shower device should ensure that water is sprayed on the car from the front, back, bottom, side and top directions, avoiding dead spots of water spray, and ensure that the water spray pressure and flow correspond to the various parts of the car to meet the requirements of the standard QC/T 476-2007. The frame structure of the rain shower pipeline is simple and beautiful while ensuring anti-rust and shock-proof. The whole equipment is reliable and simple to operate, and it is convenient for the repair and maintenance of parts.

Nozzles

1. Stainless steel nozzle is used, and it can be easily disassembled and cleaned. The spray state is solid conical, and the cone angle is 60 degrees. Spraying angle, the top nozzle is perpendicular to the horizontal plane (can also be adjusted to 45 degrees), and the nozzle design meets the national standard. The nozzles are arranged in a square grid, there is no blank area in the spraying area, and the diameter of the nozzle hole is 2.5mm to 3.0mm. The horizontal and vertical spacing of nozzles is 400mm.

2. The distance between the nozzle and the outer surface of the corresponding vehicle body: 700mm±200mm. The bottom nozzle is located 200mm below the ground.

3. The axes of the top and bottom nozzles are perpendicular to the horizontal plane, and the axes of the left and right nozzles are adjustable from 15 to 90 degrees perpendicular to the vehicle longitudinal direction, using automatic adjustment and manual adjustment. Front and rear are manual adjustment angles of 90, 45, 30, 15 degrees.
