What are the maintenance methods for touch screen? In the era of rapid technological development, touch screen displays have been widely used. Whether it is in a shopping mall, or in a hotel, in a lobby, or on some roadsides, touch screen displays have provided convenience for our work and life, and it has become closely related to our lives. The service life of the touch screen display with high cost performance is also relatively long. Even so, we still need our attention to its maintenance.
Do not use in high temperature environment
Do not use it in a high-temperature environment. When the ambient temperature reaches 40 ° C or above, it will easily cause the capacitive screen drift of the touch display screen. If it reaches this point for a long time, it will cause serious damage or even scrapping the touch screen display. It is very inconvenient for companies or individuals to cause financial losses.
Never allow strong magnetic fields to touch the display
When using the magnetic field, avoid the electromagnetic field, because the magnetic field will cause temporary aging of the capacitive screen. However, it is also necessary to pay attention to things that are magnetic, such as audio, so try not to put them close to the touch screen display.
Do not let it produce static effect
We all know that the electrostatic effect is easy to penetrate the capacitive screen. Although the glass on the surface of the capacitive screen of the touch screen display has certain antistatic treatment, it can only withstand the static electricity under a certain intensity, so we choose the touch screen protective film Please pay more attention when choosing and choose the protective film with strong anti-static ability as much as possible.
Do not allow oil or sweat to touch the touch screen
Perhaps a relatively small number of people know that oil and sweat can cause the screen to drift due to the formation of a dense conductive layer on the touch screen, so the touch screen display should be kept away from oil and sweat. Therefore, Lianchengfa advises consumers to pay attention to the above 4 points when using the touch screen display, to properly protect and maintain the correct use of the touch screen display, and use it as long as possible to avoid unnecessary economic losses.
Suction Control Valve/SCV Valve
The Suction Control Valve or SCV is responsible for the control of fuel pressure inside common rail engines. It allows only the required amount of fuel to be pumped through the system. The SCV is a wear item, that is a good part to cross off your list of things to do – just like a cam / timing belt.
The Suction Control Valve is generally installed at the inlet of the high-pressure fuel pump. It is a proportional solenoid valve, controlled by the electronic control unit (ECU), which can control the amount of oil entering the high-pressure fuel pump, thereby controlling the oil pressure in the common rail pipe. The good work of this component can not only ensure that the vehicle can run normally but also enable the engine to run in the most fuel -- efficient state to achieve the effect of saving fuel.
The use tolerance of SCVs is very small and will soon be affected by contaminated fuel and / or fouling.
Contaminated suction control valves can cause a vehicles Electronic Control Unit (ECU) to cause surging and other unwanted effects as it tries to correct fuel pressure levels.
