Vehicle Rain Test Laboratory Wuxi Huanwei is trustworthy

Basic requirements for equipment functions and structural technical requirements
The main body and internal components of the rain test chamber should be made of waterproof and anti-corrosion materials, the buried pipeline system should be made of pipes, and the valves, water pumps, rain systems, etc. should be made of stainless steel.
The design of the ground, which is low on the inside and high on the outside, requires quick and easy drainage (it is recommended to use stainless steel grilles for drainage in other parts except the wheel-rolled part).
The floor of the rain test room must be waterproofed, and a water-retaining curtain should be added to the lower part of the door to prevent water from flowing out of the door.
The average rainfall intensity at the front of the car body is /, and the average rainfall intensity at the rear and top of the car body is /. It is required that the head flow rate of the water pump and the pressure diameter of the pipeline meet the system usage requirements (water pump water supply pressure).
The bottom and wall of the pool are tiled to facilitate cleaning. Drainage holes are installed at the bottom. An overflow pipe is set on the wall of the pool. The water intake pit is set slightly lower and a bottom valve is set for water intake.
The circulating water system should be set up for one use and one backup. An unloading valve should be installed at the outlet of the water pump. This unloading valve will automatically open for drainage when the pressure in the entire system is abnormally high to ensure system safety.
When selecting, positioning and installing the fan, shock absorption, noise reduction and sound insulation measures must be taken into consideration when designing the air outlet. It is necessary to ensure that the noise inside the workshop is not higher than decibels, and the noise at the factory boundary is not higher than decibels during the day and not higher than decibels at night.
The compressed air inlet of the drying operation area is equipped with a filter device and a manual exhaust valve. The exhaust time (seconds) is adjustable.
The water pump adopts Grundfos brand. Low-voltage components are of Schneider brand.
Preparation and control requirements
The lighting fixtures in the rain room should be waterproof and explosion-proof, and the illumination should not be lower than.
All electrical components in the rain room must use safe voltages, and wires and switches must be waterproof and explosion-proof.
The electronic control system adds an air switch with leakage protection.
A waterproof cover should be installed above the installation position of the water pump.
An electronic digital display instrument is installed on the electrical control cabinet to dynamically display the system pressure of the pipeline for easy observation. The electric control cabinet is placed at the side entrance of the rain room workshop (the specific location is determined on site).
The rain shower room has the function of sensing the arrival of the vehicle. After the vehicle is in place, it emits a signal light (the signal light is visible to the driver) and delays the automatic rain shower. The rain shower time is minutes. After the vehicle is in the rain, it moves forward and exits. The electric sensor Behind the door, the rain stops automatically.
The electronic control system also has a manual control function, which can control raining and stopping raining in the rain shower room through buttons. The electronic control system has the function of delayed water spraying and scheduled water cutoff.
After the project starts, the supplier will provide a set of control system design solutions to the purchaser's technical personnel, which will be approved by the purchaser. The program complies with specified equipment or technical standards higher than those specified in this Agreement. The program will be adaptable and comply with the basic requirements of the purchaser. This solution will be a mature technology that the supplier has applied in many large-scale projects.
Technical requirements for safety and protection
The design and installation of equipment and maintenance channels should comply with relevant national safety technical standards
When designing, consider preventing small product parts from falling into the equipment body and causing moving parts to be blocked. Phenomenon
The equipment must be equipped with a grounding device, and a safety guardrail must be installed around the electric control cabinet
The safety instructions and safety signs must be marked with national universal symbols, or with Chinese characters. When the equipment is shipped, all safety signs must be Post it well.
Technical requirements for spare parts and wearing parts
Provide a list of spare parts and wearing parts and a set of wearing parts when the equipment is delivered, and ensure that spare parts can be provided for a long time
