Before the concrete pump pumps the concrete, clean water should be used to lubricate the pipeline, and the mortar is sent first, and then the concrete is sent to prevent blockage. When starting to pump, the concrete pump should be running at a slow and uniform speed, and then gradually accelerate. At the same time, the pressure of the concrete pump and the working conditions of each system should be observed. After each system is working normally, the pump

Our country China began to explore the development of concrete pumps in the 1970s and introduced technology to manufacture concrete pumps in the 1980s, but the real domestic concrete pump manufacturing began. After more than 20 years of development, China has become the world's largest producer of concrete pumps. In 2007, about 3,000 pump trucks were sold, and about 6,500 trailer pumps were sold. In the same period, the total output of foreign concrete pumps was only about 12,000 units.

The pumped concrete should meet the pumpability requirements, and if necessary, the mixing ratio of the pumped concrete should be determined through test pumping.

Jun 14, 2021 (The Expresswire) -- Short Description About Concrete Placing Booms Market : A concrete placing boom is the final element of concrete mixture pipeline transportation system. It is known as a boom concrete pump because it uses a remote-controlled articulating robotic arm (called a boom) to place concrete accurately.

The use of placing booms has been wisely adopted in the Philippines, especially for building reinforced concrete frames on inner city sites where space is at a premium. Previously Saintyol DAWIN Machinery would carry out these contracts using boom pumps with additional pipeline and labour where necessary. Now, however, as a result of demand from customers, we offer a range of static pumps and stationary placing booms complete with a full installation and maintenance service.

The concrete distributor mobile spider concrete placing boom is the terminal equipment for pumping concrete, and its function is to send the pumped concrete to the formwork of the component to be poured through the pipeline.

70% of our country's area is mountainous and hilly, mainly distributed in the northwest, southwest, central China and northeast. The mountains hinder the way for mountain residents to access the outside world, and the living conditions are also very difficult. In order to build mountain areas, let them come out, and drive the economy, the country has vigorously developed mountainous roads, bridges, and housing projects. In the project, Saintyol DAWIN self-loading mixer truck played a vital role.

Hello everyone, I am Saintyol DAWIN HY3.5 automatic self loading concrete mixer truck, don't think I am just a small mixer, my skills are great! I can produce concrete on my own because of the proper flow of the "Saintyol DAWIN Family" concrete mixer truck. Let me introduce myself to you!

Everyone who has gone through hardships was once a heroic boy wish. In the future, you can realize the dream of the past in every journey. The Saintyol DAWIN self-feeding mixer will accompany you on every journey and pay tribute to you who are full of ambitions!

The high temperature problem of the automatic self loading concrete mixer is very harmful. It needs to be noted, especially in summer, many machines are prone to high temperature problems. How to avoid the high temperature hazard of the automatic feeding mixer? The editor summarizes the following points:

Most of the small concrete pumps are in the form of double cylinders. Its two hydraulic cylinders drive the two conveying cylinder pistons to work alternately, which not only makes the conveying of concrete more stable and continuous, but also greatly increases the displacement. Its working principle varies according to the distribution valve and control mode, but the main difference is still reflected in the realization of the reversing action.

The layout of concrete pump pipes must pay attention to the following points: 1. In order to reduce pumping resistance, try not to place a 90-degree elbow immediately at the outlet of the concrete pump. The correct pipe layout method is to place a 1 to 2 meter short pipe at the outlet of the concrete pump, then connect a 3 meter straight pipe and then consider the 90-degree elbow landing.

The truck for pouring concrete on the building is called a concrete pump truck.

Truck mounted wet spraying machine generally use hydraulic drive equipment for concrete conveying. The hydraulic drive equipment of wet spray trucks generally uses hydraulic cylinders to drive plunger concrete pumps to transport concrete. This type of transportation can be seen everywhere on construction sites, especially suitable for large-scale engineering construction, because the hydraulic system can be greatly improved

Common concrete spraying machines are mainly divided into two categories: dry concrete spraying machines and wet concrete spraying machines. Compared with dry concrete spraying machine, wet concrete spraying machine has low dust concentration, low rebound rate and high strength of sprayed concrete, which greatly saves costs and effectively improves the construction environment.

After working for a period of time, everyone will choose a place for vacation. Concrete wet spraying machine is a commonly used concrete wet spraying equipment. After many times of construction, it also needs to be maintained. The cured concrete wet spraying machine can not only help improve construction efficiency and shorten the construction period, but also greatly reduce the labor cost of construction.
