With the rise and prosperity of the LED industry, mobile advertising vehicles will follow. In this type of vehicle, large LED display screens or rolling systems are often installed. As the vehicle's driving and moving can be anywhere, anytime. Advertising campaigns, so mobile advertising vehicles are favored by advertisers. However, there are often some minor problems that are confusing and the number of mobile devices on the advertising vehicle is relatively high. Therefore, there is still a certain degree of difficulty in handling it. The specific processing method is immediately available!

The most common problem with mobile advertising vehicles is the appearance of a square or full screen on the led display. This is one of the highest frequency problems. When encountering similar situations, the first step is to check whether the control panel has been Turn on, and then pay attention to see if the communication line and the sending card are all plugged in. In many cases, you only need to re-send the sending card to solve it. If none of the above methods works, check if there is a problem with the data cable connection between the multimedia card and the capture card and the sending card.

Secondly, it is also very easy to encounter the problem is that when you restart the led mobile advertising car there will be prompted to say that can not find the corresponding control system. There may be two reasons for this problem. The first is that the signal acquisition line between the data transmission card and the COM port is not connected. Reconnect it. Second, there is a problem with the COM port of the computer itself, or if it has already been damaged, it needs to be replaced.

The last thing to share with the riders is how to solve the problem when the entire screen of the mobile advertising vehicle appears shaking or ghosting. When the entire screen is shaken, check the communication line between the computer and the big screen and the DVI cable connection. Is it normal? If the above two connection lines are all normal, it means that the sending card has been damaged and the sending card needs to be replaced. These are some of the problems that often occur in mobile advertising vehicles and the corresponding solutions.

Pneumatic Pump is a new type of transport machinery, is the most novel type of pump in China.Using compressed air as the power source, all kinds of corrosive liquids, granular liquids, high viscosity, volatile, inflammable, highly toxic liquids can be exhausted by light absorption.Invented by American engineer William wilton, the pneumatic pump was introduced to China.There are five kinds of materials commonly used: plastic, aluminum alloy, cast iron, stainless steel and teflon.According to different liquid media, Diaphragm Pump adopts buqing rubber, chloroprene rubber, fluoro rubber, polytetrafluoroethylene, polytetrafluoroethylene respectively.The early domestic customers bought through the importer agent, the price is expensive and the maintenance is complicated.With the development of industry, the market share of domestic Pneumatic Diaphragm Pump has exceeded that of imported products.In order to install in a variety of special occasions, used to pump a conventional pump can not pump the medium, all achieved satisfactory results.

neumatic diaphragm pump is a new type of conveying machinery, using compressed air as power source, for all kinds of corrosive liquid, with particles of liquid, high viscosity, volatile, flammable, poisonous liquid, it can be smoked light, has formed a production, product quality, are welcome.The main characteristic of this kind of pump is without irrigation water diversion, both can flow pumping liquid, and can transport fluid medium, some grain flow can control freely according to the size of air pressure, adjustable head (0 to 50 meters), air pressure or work only more than 1 kg/cm2, absolutely for fire and explosion prevention, submersible pump, self-priming pump, all impurity pump, shield pump, slurry pump function, and many features of the conveying machinery.
Diaphragm pump flow, characteristic selection
Diaphragm pump flow characteristic is refers to the medium flow through the valve of the relative flow and displacement (relative opening degree of valves), the connection between the ideal flow characteristic mainly has straight lines, such as percentage (log), parabolic and quick opening, four kinds of characteristic curve and the shape of the valve core as shown in figure 1 and figure 2.The usual ideal flow characteristics are straight line, equal percentage (logarithm) and fast opening.Parabolic flow characteristic between straight line and equal percentage, the percentage of properties such as generally available to replace, and quick opening feature is mainly used for two control and program control, so the choice of diaphragm pump characteristic is, in fact, the choice of straight lines and equal percentage flow characteristics.
