fuel level sensor circuit
The fuel tank must have a sufficient volume. On the one hand, the requirements for heat dissipation shall be met as much as possible. On the other hand, when the hydraulic system stops working, it shall be able to contain all working media in the system and maintain an appropriate liquid level during operation.
The oil suction pipe and oil return pipe shall be inserted below the lowest liquid level to prevent air bubbles from air suction and oil return splash. Generally, the distance between the pipe orifice and the box bottom and the box wall shall not be less than 3 times of the pipe diameter.
Oil suction pipe can be installed l00 μ M. the installation position of the mesh or wire gap filter shall be convenient for loading, unloading and cleaning the filter. The oil return pipe orifice shall be chamfered by 45 °. The corner faces the tank wall to prevent the return oil from impacting the sediment at the bottom of the tank, and it is also conducive to heat dissipation.
Every time you drive, you should develop a good habit and carefully check the safety condition of the vehicle.
1.Check whether the vehicle oil, brake oil, gasoline bench circle and cooling water are normal; Whether there is leakage.
2.Check whether the vehicle braking system is intact and effective; Whether the air pump and air reservoir leak; Whether the tire pressure is normal; Whether the fastening screws of the tire are loose; Whether the spare tire is intact.
3.Check whether the vehicle's direction light, brake indicator, lamp, wiper and horn are normal.
4.Check whether the vehicle steering system is intact and reliable.
5.Record the inspection, report and repair the problems found in time, and prohibit the "sick vehicle" from leaving the site.
There is a problem with the circuit of the fuel level sensor. The yellow light on the fuel gauge is just a warning. The red light indicates that the fuel tank is running out of fuel. Because the product designer considers that some people don't look at the fuel gauge when driving, he designed such a warning light. Therefore, it is the default of the manufacturer to turn on the fuel tank warning light and then go to refuel. There is no big problem, In addition, the fuel gauge has a range of 50 kilometers after it is lit, which also meets the demand of looking for xiangmai gas station and oil pump for heat dissipation.
