产品概述
The vehicle rain tightness testing equipment (rain laboratory) is used to inspect the waterproof tightness of the vehicle and the cab after the vehicle is offline, and is an important station for the offline testing of the final assembly workshop. The equipment adopts the form of equipment customization, and we are responsible for process layout design, basic design, equipment design and manufacture, transportation, installation and commissioning, training and after-sales service, which can be customized according to the model size and workshop site.
During the test, the electric control console sends a rain signal, the motor drives the water pump to send the water in the reservoir into the pipeline spray system, sets the standard rainfall through the pressure and flow control valves and instruments, and uniformly shoots to the body surface through the nozzle; the jet water drops to the bottom sink along the body surface, collects and flows into the water treatment tank, and recycles after sedimentation, filtration, and purification, saving water and environmental protection.
The equipment consists of an external maintenance room body, sprinkler system and piping device, water supply system and water treatment system, electrical control system, etc. It has the characteristics of friendly operation interface, easy maintenance, good expansion of the control system, safe and reliable operation, etc.
Main components of the equipment
| ① Chamber body The housing plate is made of polyurethane foam warehouse board or double-sided stainless steel EPS sandwich board, with high-quality color steel plate on the outside and SUS-304 stainless steel plate on the inside, which is durable; the wall plate is spliced and sealed with waterproof materials and full glue to ensure no leakage; the tempered glass visible window and top waterproof lighting are configured to facilitate external observation of the rain state. | ② Spraying system and piping device The spray pipeline uses corrosion-resistant materials (main pipeline galvanized pipes, branch pipes fixed to each spray surface bracket), the pipeline and bracket are firmly installed, and there is no vibration during spraying; the nozzle is 60° solid conical, uniformly arranged unshielded area, easy to disassemble and clean, and the angle is adjustable; the multi-stage centrifugal pump is equipped with a high-precision digital electromagnetic flow meter for measurement. |
| ③ Water supply system and water treatment system The water supply system consists of a multistage centrifugal water pump, a pressure transmitter, a filter, and an intelligent flow meter. The water treatment system includes a first-stage sediment sediment settling tank, a second-stage float filter tank, a third-stage purified filter tank, a clean water tank, and a sewage pump. The reused water is precipitated, filtered, and purified, and the quality of the effluent reaches the standard of GB 8978-1996 reused water. The upper part of the cistern is covered with a cover plate, which takes into account the safety of personnel and the protection of water quality. | ④ Electrical control system 7-inch LCD touch screen (Velantone), Chinese interface, screen direct touch options; integrated PLC and circuit breaker, Schneider and other well-known brands are used for electrical components; the control cabinet is equipped with nameplates (equipment name, manufacturer, manufacturing time, rated voltage and power), low-voltage lighting and fan cooling in the cabinet, and the main power switch is set on the outside of the cabinet; the panel includes Chinese marking buttons for operating the power key switch, operation, stop, alarm stop, emergency stop, etc. |
Features of the System
■The rain intensity is set and automatically controlled by the instrument parameters, and the pressure and flow can be adjusted to meet different standards and test purposes. ■The spray time can be set arbitrarily on the touch screen, and the equipment will automatically turn off at the specified time without manual duty. ■The system operates in two modes, automatic and manual, and adapts to different operating habits. ■Each side of the pipeline is equipped with a butterfly valve that is individually controlled and equipped with a pressure gauge group, and a manual spherical drain valve at the end, which is convenient for flushing the pipeline and removing dirt. | ■Multiple safety protection: motor thermal relay overload protection, overvoltage protection, high and low level alarm and automatic water replenishment, sewage pump level protection; emergency stop circuit consists of hardware, does not rely on PLC, cut off the control power supply and output power supply when stopping. ■The inlet and outlet of the filter are equipped with pressure sensors. The water pump cannot be started when the pressure difference formed by the filter bag clogs reaches the set value, which automatically reminds maintenance. ■Water conservation and environmental protection: Rainwater is recycled after precipitation, filtration and purification; sewage can be treated uniformly according to local regulations through the sewage main pipe. ■The equipment is easy to maintain, the control system reserves the ability to expand, and the workshop management system can be accessed as needed. |
Control systems and field scenarios
 Touch screen "Process screen": real-time display of each pipeline flow, pressure, pool level, fill valve and each pump operating status, with liquid level, overpressure alarm prompts |  Pump valve area and water circulation system: one by one circulating water pump, bag filter, pressure regulator, electromagnetic flowmeter and electric valve |
 Equipment external piping layout and tempered glass observation window |  Nozzle and spray line arrangement: spacing 400 × 400 mm evenly arranged, no dead angle spraying |
Structure & Components
 Three-dimensional schematic of the chamber: splicing-type library board structure, observation windows on both sides |  Tempered glass viewing window: 1200 mm away from the ground at the bottom of the window, taking into account both lighting and observation |  Inlet and outlet use PVC quick rolling shutter door with observation window, sealed and impervious to water |
Pool level control: Adopt an input pressure transmitter (recommended by Sunnys) to convert the measured medium pressure into a 4 ~ 20 mA DC/1 ~ 5 V DC standard signal, which can be used in conjunction with the PLC to achieve five-stage liquid level control - ultra-high liquid level (alarm before overflow), high liquid level (automatic stop water replenishment), low liquid level (automatic water replenishment), ultra-low liquid level (water pump protection), and bottom liquid level (sewage pump protection). The water collection system consists of an accumulation tank, a sewage tank and a clean water tank: a galvanized grille is laid at the floor interface, and the interface is equipped with a stainless steel filter screen to block large particle debris such as tape and paper; a 400 × 400 × 250 mm sewage well is set at the lowest point of the sewage tank, and the sludge is regularly discharged by the sewage pump. |  Input type liquid level sensor and five-stage liquid level control principle |
