The core function of the automotive water spray unit
The automotive water spray unit may seem insignificant, but it is a crucial component for ensuring driving safety. It is mainly composed of a water storage tank, a water pump, a piping system, and a nozzle, and it performs multiple important functions during daily driving.
Firstly, it acts as a "cleanser" for the driver's field of vision. During driving, the windshield is bound to accumulate dust, insect corpses, bird droppings, etc. Especially during long-distance driving, in rural areas, or in spring and autumn seasons, these stains can severely obstruct the driver's view. At this time, the water spray unit uses the water pump to draw the glass water from the water storage tank, and through the piping system, it is delivered to the nozzle. The water is sprayed in a mist or fan-like pattern onto the windshield, along with the windshield wipers, to quickly clean the stains, ensuring the driver has a clear view at all times and can promptly detect obstacles and traffic signs on the road, significantly reducing the risk of traffic accidents.
Secondly, it effectively protects automotive components. If the stains on the windshield are wiped directly with the wiper, the hard impurities will have intense friction with the wiper rubber strip and the glass surface, not only accelerating the aging and cracking of the wiper rubber strip and shortening its lifespan, but also leaving fine scratches on the glass, affecting the transparency and aesthetics of the glass. However, the water spray unit first moistens and softens the stains, and with the reduced friction during the wiper operation, it can easily remove the stains while reducing damage to the wiper and the windshield.
Furthermore, in special weather conditions, the role of the water spray unit is even more indispensable. In winter, when the temperature is low, the windshield is prone to fog or thin ice. The glass water containing anti-freezing components can quickly dissolve the ice layer and disperse the fog. During rainy weather driving, the glass water can neutralize the acidic components of the rainwater, reducing the corrosion of the windshield by the rainwater, and at the same time improving the scraping effect of the wiper, avoiding the formation of a water film on the windshield that affects the view.
Common faults and troubleshooting methods of the automotive water spray unit
Insufficient water spray or no water spray at all
This is the most common fault, and there may be multiple underlying causes. If the water storage tank is low on water, open the engine hood to check the water level in the water storage tank. If the water is insufficient, add water that meets the specifications. If the nozzle is clogged, dust, impurities, or sediment in the water will block the tiny holes of the nozzle. At this time, use a fine needle or toothpick to gently clear the nozzle and remove the blockage. Be careful when operating to avoid damaging the nozzle.
If the above methods cannot solve the problem, it is likely that the water pump is faulty. When the water spray switch is turned on, carefully listen to whether there is a motor running sound in the engine compartment. If there is no sound, it may be that the water pump motor is burned out or there is a circuit fault. Burned-out motors usually occur due to frequent and prolonged operation of the water spray switch, causing the motor to operate beyond its capacity. This situation requires replacing the new water pump; if it is a circuit problem, the fuse may be burned out or the wiring may be short-circuited. It is recommended to go to a professional repair shop for inspection and repair.
Leaking of the glass water
If there are traces of glass water on the ground, it indicates a leakage problem with the water spray unit. It may be that the water storage tank is aging and cracked, and after long-term use, the water storage tank is prone to brittle cracking due to the erosion of the glass water chemical components and the influence of environmental temperature changes. At this time, a water storage tank that is compatible with the vehicle model needs to be replaced; it may also be that the connection of the piping is loose or the piping is broken. Check if the piping interface is firm. If it is loose, reinsert it firmly. If the piping is broken, a new piping needs to be replaced. Another situation is that the sealing ring between the water pump and the water storage tank is worn, causing a leak. Replacing the sealing ring can restore the sealing property.
Abnormal spray position
If the nozzle angle is offset, the glass water will not be accurately sprayed onto the appropriate position of the windshield, affecting the cleaning effect. This situation is mostly caused by vibrations and external collisions during driving or the impact of a high-pressure water gun during car washing, causing the nozzle to shift. The solution is quite simple. Use a small tool to gently adjust the angle of the nozzle until the windshield washer fluid can evenly cover the main area of the windshield.
Daily maintenance suggestions for the automotive washer fluid dispenser assembly
To extend the service life of the washer fluid dispenser assembly and reduce the occurrence of faults, daily maintenance is indispensable. First, choose high-quality washer fluid. Avoid using tap water or inferior washer fluid. Tap water contains minerals and is prone to forming scale in the reservoir and pipelines, blocking the nozzle and pipelines. The chemical composition of inferior washer fluid may corrode the reservoir and pump components. Secondly, regularly check the liquid level of the reservoir and add washer fluid in time according to the usage situation to avoid damage caused by the pump running empty. Additionally, you can clean the nozzle once every certain period to prevent impurities from accumulating and blocking. Before winter arrives, replace the anti-freezing washer fluid in time to prevent the washer fluid from freezing, cracking the reservoir or damaging the pump.
