Small concrete pump trucks, also known as concrete pump trucks, use pressure concrete along the pipeline for continuous conveying machinery. The small concrete pump truck is mainly composed of a pump body and a conveying pipe. The pump body is installed on the chassis of the automobile, and then equipped with a telescopic or inflatable fabric rod to form a pump truck.
According to the structure, small concrete pump trucks can be divided into piston type, squeeze type and hydraulic diaphragm type. What are the characteristics of the small concrete pump truck structure? With the construction of the second-class towns and new rural areas, the concrete pump comes from another concrete pump model and has a very special large-scale small concrete pump truck. Since the mass production of large-scale small concrete pumps, they have been well received by users. In the current economic downturn, the market for commercial housing construction, railway and bridge construction in large cities is blocked, and the demand for small concrete pumps is large.
Structural Features of Small Concrete Pump Trucks Small concrete pump trucks are a modification of the chassis made of trucks. They are mounted on the chassis with motion and power transmission equipment, pumping and mixing devices, fabric devices and other auxiliary devices. The power of the concrete pump truck transmits the power of the engine to the hydraulic pump group or the rear axle through the power distribution box, and the hydraulic pump pushes the piston to drive the concrete pump to work. Then use the pump bar and the pipe, the concrete will be transported to a certain height and distance. In addition to driving the pump truck, the small concrete pump truck engine is also used to drive the pump mechanism, the stirring mechanism and the fabric working mechanism.
The displacement of a small concrete pump truck depends on the number and diameter of the concrete cylinders, the reciprocating speed of the piston and the volumetric efficiency of the inhaled concrete cylinder. Clean the entire vehicle after each start and pump completion, check and keep the grease in the manual grease pump tank, pull the handle of the grease pump, observe the agitated bearing, and the S tube size shaft is after the cleaning oil overflows. Pull the manual grease pump handle 10 times per hour during work. The small aggregate concrete pump truck lubrication system should be kept clean to prevent dust and other impurities from entering, do not touch the acid and alkali substances, and the system should be cleaned every 500 hours. When the transport cylinder coating (0.2-0.25mm) is not worn and concrete mud or sand appears on the back of the concrete piston tank, it indicates that the piston has been ground and the concrete seal, guide ring and dust ring need to be replaced immediately.
