[Asia Pump Network News] concrete pump, also known as concrete pump, pump and delivery pipe. It is a kind of machinery that uses pressure to convey concrete continuously along the pipeline. Nowadays it is mainly used in the construction of houses, bridges and tunnels. It is mainly composed of the pump body and the delivery pipe, according to the structure is divided into piston type, squeeze type, hydraulic diaphragm type. Different methods of maintenance of structural forms vary, as follows: Concrete pump should be how to maintain? 1, Hydraulic transmission concrete pump consists of hopper, hydraulic cylinder and piston, concrete cylinder, distribution valve, Y-shaped pipe, flushing equipment, hydraulic system and power system. The hydraulic system pushes the piston back and forth by pressure. When the piston moves backward, the concrete will be pressed into the conveying pipe through the Y-shaped pipe before pushing. After the pump concrete is over, clean the pump body and delivery pipe with high-pressure water or compressed air. 2, piston displacement of concrete pumps, depending on the number and diameter of concrete tanks, piston reciprocating speed and volume of concrete cylinder suction efficiency and so on. Mortar concrete pump feeding process appears automatic shutdown motor The concrete mortar pump inspection, the main piston system pressure was normal, and the current is abnormal. It can be judged, the fault may be caused by the motor overload rather than load overload. Because the main piston pump is a constant power variable pump, if the current is too high will cause the motor overload. Sewage valve: open the tank for cleaning to exclude sewage oil, usually closed. Operate the blowdown valve once a week for 24 hours after shutting down to remove the water that has settled on the bottom of the tank. 3, High-pressure oil filter (one each for main system and boom system): When the prism pointer on the oil filter refers to the green mark, it indicates that the work is normal and the filter plug is not blocked; when the pointer points to the yellow mark, Filter plugging phenomenon, but can continue to work; when the pointer points to the red logo, indicating serious blockage of the filter can not continue to work, you must immediately replace the filter, each time you replace the hydraulic oil filter should be replaced at the same time. Air filter (hydraulic tank): to prevent foreign debris mixed with the air filter, replaced once every six months. Fastening elements: Before daily boot check the fasteners are loose, such as loose should be fastened before further work. Industry Internet (Xiamen) Technology Co., Ltd.
