Concrete pump machine is an effective tool for concrete pumping, which is composed of pump and pipes. Under the influence of pressure, concrete is pumping continuously along the pipeline. I’d like to share some basic knowledge of pumping machine from such aspects: concrete pump models, construction of pumping system, concrete pump working principle, and manufacturers.
Concrete pump models
Generally speaking, concrete pump is divided into two types: diesel concrete pump and electric concrete pump. Our company can provide you different concrete pump models.
Models of diesel concrete pumps in our company are BS30-10-56R, HBTS40-10-82R, HBTS50-12-62R, HBTS60-13-129R, HBTS80-16-129R, HBTS90-18-176R.

of delivering pipe
There are five models of electric concrete pumps: BS30-10-37, HBTS40-13-45, HBTS50-12-75, HBTS60-13-90, HBTS80-16-110In order to understand concrete pump working principle, I’d like to introduce the construction of pumping system to you in advance. Because pumping system is the main system for the process of pumping concrete.

The structure of pumping system
This system consists of the hopper, concrete conveying cylinder, main oil cylinder and so on.
1. The hopper
The hopper, welded by steel plates, is used for storing concrete to make sure the normal process of feeding. It is used for feeding. In addition, there is a S valve in it.
2. Concrete conveying cylinder
The concrete conveying cylinder valve connects the hopper and water tank, in which there are two concrete pistons.
3.. Main oil cylinder
The last part is main oil cylinder. It is plated with hard chromium on the surface in order to avoid rusting.
In order to maximize pumping efficiency, our company always adopts high-quality parts. Pumping system has to endure a great impact when concrete pump starts working. So the parts have to be wear resistant. Take S valve as an example. S valve is in the hopper, which can compensate wear clearance automatically and get a great sealing performance. It consists of wear plate and wear ring. They are made of hard alloy, thus the service life of wear plate and wear ring is extended.
Concrete pump working principle
When the machine start to pumping concrete, the pumping system works in this way.
1. After pressure oil of the hydraulic system enters into the main cylinder, one piston rod is extended and the other piston rod is retracted.
2. Then, the concrete conveying piston, which connects the main cylinder piston rod, starts self-absorbing in the conveying cylinder when it has to retract.
3. The concrete in the hopper is sucked into the conveying cyclider under the influence of atmospheric pressure and stirring blade.
4. At the same time, under the action of oil pressure, the other main cylinder promotes the piston rod out of the cylinder. Meanwhile, concrete piston pushes concrete out of this conveying cylinder.
5. After this action is completed, the system automatically changes the direction and makes pressure oil get into the other main cylinder. Later, it will complete another travel of sucking and pumping.
In short, this a repeated process. Just in this way, concrete in the hopper is continuously sucked in and out of the conveying cyclinder and pumped to the operation point.
After learning the working principle, it is time to choose a proper concrete pump machine manufacturers.
