Although most of the concrete pump trucks are operating using the engine's motive, the entire circuit system of the vehicle provides great normal operation guarantee for other equipment. In addition to being able to require a battery to provide current when starting up, after the concrete pump truck is started, the entire circuit system is in full operation.
Ninety-nine percent of the concrete pump trucks in the current market are converted from used truck chassis. On the other side of the chassis, there are two batteries that can provide power for the entire pump truck, and the concrete The battery voltage of the pump truck is similar to that of the batteries on ordinary cars, both of which are standard voltages of 12V. After two series connections, the voltage is 24V. However, after the engine is started, the generator will charge the battery, so the voltage will continue to rise. After adding the pump truck to work for a long time, the battery voltage of the pump truck needs to be detected immediately after parking. The resulting voltage data should all be between 26-28V. If the pump's voltage is still less than 20V when the pump truck has been parked at 3H, then it is necessary to consider replacing the battery.
Although the concrete pump truck has two batteries, there are many places where the pump truck consumes electricity, such as a display screen, a remote control signal transmission device, a remote controller, etc. In addition, various lighting devices and cooling fans on the vehicle use electricity. It is supplied from the battery. Therefore, the distribution system installed on the concrete pump truck is also of high importance in the entire vehicle equipment. Nowadays, there are more and more kinds of vehicle circuits, unlike some old-fashioned mechanical devices that only had a few wires. However, after the current distribution system is complicated, there will be higher requirements for the entire vehicle's line quality. In particular, the quality of each line with a rotating speed and high temperature requires good performance in anti-rotation and high temperature resistance. (Text / Sun Ni)
