What is a small concrete pump truck? What are the characteristics of small concrete pump truck structure

Small concrete pump truck, also known as concrete pump truck, is the use of pressure concrete along the pipeline for continuous delivery of machinery. Small concrete pump truck is mainly composed of pump body and delivery pipe, pump body mounted on the chassis of the car, and then equipped with retractable or inflatable fabric rod to form a pump truck. By structure, small concrete pump truck can be divided into piston type, squeeze type, hydraulic diaphragm type. What are the characteristics of the structure of small concrete pump truck With the construction of secondary cities, towns and new rural areas, concrete pump derived from another concrete pump model with a very specific - large Aggregate small concrete pump truck. Large aggregate small concrete pump since the beginning of mass production, by the majority of users alike, in the current economic downturn, the construction of commercial housing in large cities, railway, bridge construction is blocked market environment, the small aggregate concrete pump Demand is strong. Structural characteristics of small concrete pump truck Small concrete pump truck is the transformation of the chassis made of trucks, which is installed in the chassis with movement 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 transfer case, and the hydraulic pump pushes the piston to drive the concrete pump to work. Then use the pump truck cloth rods and pipes, concrete will be transported to a certain height and distance. Small concrete pump truck engine in addition to driving pump truck travel, but also used to drive pumping mechanism, stirring mechanism and fabric working mechanism and other devices. 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 concrete cylinder sucked in. After each start-up and pump finished washing the entire vehicle, check and maintain manual grease pump oil tank filled with grease, pull the handle of the grease pump to observe the mixing bearings, S tube size shaft at both After the clean oil overflows. In the course of work, pull the manual grease pump handle 10 times every hour. Small aggregate concrete pump truck lubrication system should be kept clean to prevent dust and other impurities to enter, do not come into contact with acid-base substances, the system cleaned once every 500 hours of work. When the transport cylinder coating (0.2-0.25mm) is not worn away and the rear of the concrete piston tank that appears concrete slurry or sand, indicating that the piston has been grinding the need to immediately replace the concrete seal, guide ring, dust ring.
