Paper Wiper working principle and maintenance introduction
Wipers, also known as wipers, waterpipes, wipers or windshield wipers, are used to brush off the rain and dust attached to the windshield of the vehicle to improve the driver's visibility and increase driving safety. Because the law requires that almost all local cars with wipers. Hatchback and SUV vehicles such as the rear window is also equipped with wipers. In addition to cars, other means of transport are also equipped with wipers, such as trains, trams and so on. A part of the engineering machinery, such as cranes, is also equipped with wipers. Here to take you to understand the working principle of Paper Wiper paper.
Paper Wiper: Basic introduction
Windshield Wiper, refers to the installation of the windshield in front of the chip structure, by the motor, reducer, four link mechanism, wiper arm mandrel, wiper blade assembly, etc. The role is to remove the windshield on the line of rain and dust and dust. Intermittent flexible wiper, by the driver in accordance with the rain and the line of sight to make their own adjustments. With other ordinary car wipers installed the difference is that it can be based on changes in the speed to automatically lift the scraping speed. Because in the same size of the rainfall, the faster the speed, the more the face of the rain, and if the parking, wipers slow down the operation will reduce the noise.
Paper Wiper: operating principle
The power source of the wiper comes from the motor, which is the core of the wiper system. The quality requirements of the wiper motor are quite high. It uses a DC permanent magnet motor, installed in the front windshield wiper motor and worm gear parts are generally made into one. The role of the worm gear mechanism is to slow down the twist, the output shaft drive four-bar linkage mechanism, through the four-bar linkage mechanism to change the continuous rotation of the left and right swing movement.
The wiper motor uses a 3-brush structure for easy speed change. Intermittent time controlled by the intermittent relay, the use of the motor's return switch contacts and relay resistance and capacitance of the charge and discharge function of the wiper in accordance with a certain period of scrapping. The wiper blade is a tool that directly removes rain and dirt from the glass. The blade is pressed against the glass surface by means of a spring bar, and its lip must be aligned with the glass angle to achieve the desired performance.
Under normal circumstances in the car combination switch handle wiper control knob, with low speed, high speed, intermittent 3 stalls. Handle the top is the scrubber key switch, press the switch with a washing water spray, with the wiper to wash the windshield. The scrubber system is a very common device in the car. It consists of a water storage tank, a water pump, a water pipe and a water nozzle. One of the storage tank is generally 1.5 to 2 liters of plastic cans, water pump is a micro-electric centrifugal pump, through which the storage tank of the washing water to the nozzle, by 2 to 4 nozzle squeeze Wash the water into a small jet spray to the windshield, with the wiper to play the role of cleaning the windshield.
Paper Wiper: wiper control system
Wiper control system (wiper control system) through the electronic control system can not only achieve the delay control of the wiper, but also to achieve some other complex control. The electronic control system consists of a two-speed motor and two limit switches. The following functions are available via a handle switch: cleaning, wiper, high speed wiper, low speed wiper, intermittent wiping and delay control. Complex electronic control system can also achieve the swing bar positive pressure control and rainfall sensor control.
Paper Wiper: How to use it
Rainy days, when the rain falls on the window glass, the front of the car line of sight quickly hindered, vehicles, pedestrians and scenery have become blurred. At this point, open the wiper, the car will be a clear front. If you drive a vehicle on a rainy day without failing to use a wiper or a wiper, it will be very detrimental to traffic safety.
(1) Before heavy rain, check whether the Paper Wiper is working properly.
(2) rainy days, rapid and large raindrops hit the windshield, even if the wiper movement and then fast, it is difficult to scratch the rain, resulting in the driver's line of sight affected, in order to ensure traffic safety, should immediately stop.
