The first type of concrete pump is attached to a truck or longer units are on semi-trailers. It is known as a boom concrete pump because it uses a remote-controlled articulating robotic arm (called a boom) to place concrete accurately. Boom pumps are used on most of the larger construction projects as they are capable of pumping at very high volumes and because of the labour saving nature of the placing boom. They are a revolutionary alternative to line-concrete pumps.
The second main type of concrete pump is either mounted on a truck or placed on a trailer, and it is commonly referred to as a line pump or trailer-mounted concrete pump. This pump requires steel or flexible concrete placing hoses to be manually attached to the outlet of the machine. Those hoses are linked together and lead to wherever the concrete needs to be placed. Line pumps normally pump concrete at lower volumes than boom pumps and are used for smaller volume concrete placing applications such as swimming pools, sidewalks, and single family home concrete slabs and most ground slabs.
There are also skid mounted and rail mounted concrete pumps, but these are uncommon and only used on specialized jobsites such as mines and tunnels.
In general, it is composed of power system, mechanical system, hydraulic system, lubrication system and electrical control system. The main process is that the concrete is sucked and pushed by piston under high pressure.
1.Main power system
The main power system includes engine and oil pump. The oil pump is driven by engine, which can provide oil for the hydraulic system. The engine includes electric engine and diesel engine. Both the engine has lower emissions, low energy consumption and less noise.
2.Mechanical system
S-valve adopts sealing structure with good sealing quality, which can automatically compensate wear clearance. The s-tube of trailer concrete pump for sale is made from wear-resisting materials. The shaft head of s-tube uses high-strength material to avoid shaft head rupture.
The main oil cylinder adopts sealing technology, which solves the emulsification problem of hydraulic oil. The inside surface of cylinder is covered with hard chrome, which improves performance of wear-resisting and anti-corrosion.
The special design of hopper has good absorption with no accumulated concrete materials. It is also convenient to clean.
3.Electrical control system
The electric control system has excellent control interface, strong anti-interference ability and strong waterproof and dustproof ability. The electrical control system of trailer mounted concrete pumps for sale can be operated manually or operated by remote control when pumping.
4.Hydraulic system
It adopts open system. The oil pump offers hydraulic oil for main oil cylinder and swing cylinder. The hydraulic system can realize positive pump and reverse pump. In normal working condition, the use of positive pump can push the concrete and the reverse pump means concrete sucking in pipeline. While the reverse pump is mainly used to remove blockage and clean pipeline.
Oil pump drives the oil entering into the main cylinder through the hydraulic system. When one piston in the pumping cylinder extends, the hydraulic system makes the other piston rebound through pressurized oil in the sealing pipeline. The concrete conveying piston connected to the main cylinder piston rod is self-absorption in the conveying cylinder. The concrete in the hopper is sucked into the conveying pipe through the suction port of the valve under the effect of atmospheric pressure. At the same time, under the action of oil pressure, the other main cylinder promotes the extension of piston rod and pushes the piston to convey concrete in the cylinder through pressure, and then the concrete enters the pipelines. After completion of above procedures, the system changes the direction to press oil into another main cylinder, completing another delivery process. So repeatedly, concrete in the hopper can be continuously delivered to pipeline. Through the pipeline, the concrete can reach working point to complete the pumping work.
Faced with so many models, you must be anxious about selecting which one to meet your construction. You can follow the following tips to fine the proper concrete pumps.
First, choose the engine types, diesel or electric engine.
Second, according to construction project and horizontal and vertical conveying distance, you can make sure pumping pressure.
Third, choose the distribution valve form according to aggregate diameter. There are gate valve and s-valve for selecting.
Last, make sure the lowest working temperature, whether there is a need of antifreeze system.
