The small concrete pump truck has been modified on the frame. It is equipped with motion and power transmission equipment on the chassis, pumping and mixing equipment, distribution equipment and other auxiliary equipment. The power of the small concrete pump truck passes the power of the engine through the power transfer box to the hydraulic pump group or the rear axle. The hydraulic pump drives the piston to drive the concrete pump. The concrete is then conveyed to a certain height and distance by using the distributing rod and the conveying pipe on the pump truck. This article introduces the operating system and performance of the pump truck.
Small concrete pump truck The electrical control system has five control methods. There are mainly mechanical, hydraulic, electromechanical control, programmable logic controller and logic circuit control. In addition to installing electrical control system to complete the control task, the small concrete pump truck is equipped with a manual control operation system, which is also part of the control system. If mechanical control is adopted, rod operation mechanisms and flexible shaft operating mechanisms usually have two ways.
The control system of small concrete pump truck mainly chooses flexible shaft control mechanism. The control system of the pump car is mainly used to control the flow rate and engine speed of the main hydraulic pump, thus changing the concrete displacement of the pump truck.
The small concrete pump truck sometimes needs to park for a long time because the construction site is not started. When parking, attention should be paid to the maintenance and maintenance of mechanical equipment. The editor of this article will introduce you to the maintenance items that you should pay attention to when you don't use pump trucks for a long time.
1. before the long-term storage of the pump truck, the machine must be maintained, repaired and damaged, and thoroughly cleaned to keep the technical condition in good condition.
2. small concrete pump trucks should be parked in dry rooms. Those who must be outdoors must choose a flat floor and cover them with wooden boards. Cover the hood with the engine cover.
3. store batteries. The battery should be removed and placed in dry, frostproof place. In order to keep the surface clean and dry, it is forbidden to place conductive objects on the battery. When removing the battery, please cut off the negative line and cut off the positive line. When installing, please connect the positive pole to the negative pole. Because the electrical system of the small concrete pump is grounded, it prevents the occurrence of a short circuit when the battery is removed and installed. Lead acid batteries should be charged once a month.
4. anti rust treatment. Before storing the small concrete pump, the size of the outer surface antirust paint should be used to determine whether the paint is repaired through the paint or the whole machine is painted, the ironing plate, the bucket of the loader, the scraper of the grader, and so on.
