How can I clean a pump truck of dirt during work? This article describes the importance of emergency drive hoses when cleaning agitator day pumps.
During the cleaning process of the pump truck, it is first necessary to prepare the emergency drive hose in time, close the pump truck, and remove the high-pressure oil pipe joint on the hydraulic motor. Breathing requires placing a wooden wedge between the support rollers and the raceway to control the rotation of the pump truck. Turn off the daily pump engine, remove the high pressure oil pipe of the hydraulic motor of the pump truck, the pump truck can rotate freely, control the rotation of the mixing drum, repair the hole to the lower part, then open the maintenance hole, and then remove the concrete in the drum. At this time, pay attention to safety. After the concrete is discharged, the original shape of the pump truck is restored.
The above are the problems that need to be paid attention to in the cleaning process of the pump truck. Use only when cleaning. Mixing daily pumps are mainly used for concrete. However, during the operation, attention must be paid to the entire operation process.
When it comes to the operating knowledge of the pump truck, it is first necessary to carefully check whether the steering, braking and lighting are sensitive. If there is a problem, the pump van vanes wear within normal limits, and the U-bolts are fine in the chassis and sub-frame. Second, the rotating rollers and rollers must be touched by hand during operation. Otherwise, it's easy to make mistakes.
1. High voltage is very dangerous. Unable to remove common rail piping.
With the increasing popularity of electronically controlled engines, proper maintenance of electronically controlled engines is very important. However, when working on the pump truck, it is forbidden to remove all oil pipe joints on the high pressure side, such as high pressure oil pipes and common rail oil pipes. The common rail oil line pressure is high and the engine needs to be disassembled after stopping the pressure.
2. Potential killer of tire drum kits
The tires of the pump truck, especially the front wheels, are very dangerous. While driving, day pump tires can cause accidents due to bumps, which are even more dangerous on the highway. Therefore, once checked, the photosensitive drum assembly should be replaced in time. When you come across a tire drum kit, change your tires in time.
