Automobile water jet motor function
The main function of the automobile water jet motor is to convert the rotating motion of the motor into the reciprocating motion of the scraper arm through the connecting rod mechanism, so as to realize the wiper action . When the water jet motor is activated, the wiper starts to operate. By choosing different speed gears, the current intensity of the motor can be adjusted, and then the speed of the motor and the moving speed of the scraper arm .
The working principle of the water jet motor is to convert the rotating power of the motor into the back-and-forth movement of the scraper arm through the connecting rod mechanism, so as to complete the action of the wiper. Specifically, the water jet motor is usually installed in the front engine compartment of the car and is connected to the control switch of the wiper. When the driver operates the wiper, the water jet motor starts to work, sending water through the hose to the wiper and then spraying it onto the windshield, helping to remove rain and dirt and ensuring that the driver can clearly see the road ahead .
In addition, the performance of the water jet motor has a great impact on the efficiency of the wiper. A good sprinkler motor should be able to work stably in a variety of different weather and road conditions, ensuring that the wiper can effectively remove rain. At the same time, the energy consumption of the water jet motor will also affect the fuel consumption of the car, so the choice of lower energy consumption of the water jet motor is helpful to reduce the fuel consumption of the car .
The main causes and solutions of automobile sprinkler motor failure :
The fuse or line of the combination switch is faulty : check whether the fuse and relay of the sprinkler motor work normally, if the fuse or relay is abnormal, replace it in time; If there is a problem with the line, repair the line .
spray pipe blocked : check whether the pipe and nozzle between the liquid storage tank and the water pump are blocked. If they are blocked, use a pin to clear or clean .
motor fault : if there is power at the motor but does not work, the motor may be damaged, need to replace the new motor .
motor belt loose : open the engine cover to see, if the belt loose, pull it .
brush damage or circuit problem : check the brush, motor leads, control switch leads and other parts, repair or replace .
pump gland is too tight or armature coil local short circuit : need professional maintenance .
nozzle blockage : due to dust intrusion or water quality problems lead to nozzle blockage, should be cleaned in time or replace the new nozzle .
The working principle and common fault phenomena of automobile sprinkler motor :
Working principle : The water jet motor drives the water pump by electricity, and the glass water is ejected through the nozzle for cleaning the windshield.
Common fault phenomena : sprinkler motor can not start, water spraying is not smooth, water spraying is unstable, excessive noise, water leakage, etc. These failures may be due to motor failure, poor circuit contact, power supply problems, blocked nozzles, water pump failure, etc. .
Prevention and maintenance recommendations :
Check fuses and relays regularly to ensure that they are working properly to avoid the failure of the sprinkler motor to start due to blown fuses.
Keep nozzles and pipes clean : Clean nozzles and pipes regularly to prevent dust and mud from clogging nozzles and pipes.
Handle the pump exhaust : After replacing the pump or pipe, ensure that the exhaust is handled correctly to avoid idling of the pump blades.
professional maintenance : When encountering complex faults, it is recommended to seek the help of professional automobile maintenance technicians to ensure the quality and safety of maintenance.
