The fine stone concrete pump is a special type of concrete pump. This concrete pump is widely used in floor heating projects and floor construction, so it is welcomed by the majority of construction parties. So on the construction site, what are the pumping requirements of the fine stone concrete pump? Now let’s take a closer look.

The cutting ring of the concrete pump is originally a vulnerable part, which is used to make it repeatedly wear and tear during the working process. Under normal circumstances, the wear rate of the cutting ring can only be reduced by improving the pumpability of the concrete. The cutting ring can be reduced by checking and tightening the nuts to ensure that the gap between the cutting ring and the glasses plate is about 2 to 4 mm. Accidental damage.

More and more customers will encounter a lot of problems in the process of using the wet spray machine. Have some questions about the maintenance of the wet spray machine? Below, Saintyol DAWIN Machinery will answer your questions one by one!

Check the pressure of the main pump system of the concrete delivery pump (during pumping operation). If it does not reach the specified value, check the overflow valve and the main oil pump. For closed systems, under normal circumstances, the concrete pump motor starts and the charge pump works, and the pressure display should be around 2.5MPa. If the pressure is insufficient, adjust the charge pump safety valve and check the wear of the charge pump.

Concrete pumps and wet spraying machines are widely used products in construction. They have the advantages of uniform mixing of slurry, good stability, and easy adjustment of the ratio of mortar, stone and cement. The correct use of concrete pumps and wet spraying machines is the key to prolonging equipment life and improving production efficiency. So, how can we maintain the details to improve the service life of the fine stone concrete pump? Based on years of experience,

The concrete pump is mainly used for the secondary pouring of the construction project under construction. The concrete pump is mainly used to transport the mortar by hydraulic means. The reciprocating operation of the double cylinder is filtered through the vibrating screen to complete the transportation of various mortar and fine stone concrete. . Saintyol DAWIN Concrete Pump has the advantages of large capacity, high pressure, labor-saving, material-saving, and convenient movement.

What are the pumping principles of wet spray truck? How does the concrete pump pump concrete? Based on long-term repeated tests and customer surveys, Saintyol DAWIN believes that there are many factors that affect the suction performance of the mixing trailer pump pumping system, which are independent and affect each other, including the angle between the conveying cylinder and the horizontal plane, and the reversing frequency of the main hydraulic cylinder.

The pump pipes have pressure parameters, and different pump pipes are selected according to the delivery pressure of the pump truck.

The fine stone concrete pump is a kind of concrete transportation equipment developed for the characteristics of underfloor heating construction. Because of the large area and high efficiency construction on the underfloor heating engineering filling layer or mortar filling layer, it is highly anticipated by a wide range of construction companies. So why can the fine stone concrete pump have such an effect? ​​

Generally speaking, the normal service life of the mixing pump is about seven or eight years. But if there is no good maintenance, the service life may have to be compromised. If there is correct operation and reasonable maintenance, there is no problem with the mixing pump for more than ten years. How to maintain the mixing pump to last longer?

The operation of the self-loading mixer is simple, but it also requires professional training. It can not be operated casually. Here are the operating instructions of the self-loading mixer. Let's take a look.

Nowadays, the popularity of online information has greatly changed our way of life. You can buy what you like without going out. Of course, when buying things online, asking for the price is the first thing to compare, and the second thing to compare is the price. After many inquiries, you will find that the prices given by each merchant are very different. What is the reason for this phenomenon?

The strict use requirements of mining wet concrete spraying machines need to be known in order to ensure the safety of users and the service life of the machine.

Paying attention to details is the principle we must abide by when we do things. This is especially true when driving a self-loading concrete mixer. The details of driving a self-loading concrete mixer are:

Why is the small automatic self loading concrete mixer so hot now? It definitely has its advantages? I don't know how much you know about the small automatic feeding mixer. Let's talk about its advantages. Let's take a look.

The automatic self loading concrete mixer has multiple functions, making the entire construction easier. It is also inevitable that there will be problems in the construction of the automatic loading mixer, such as the loading and unloading is not smooth, there is a phenomenon of material blocking, how to deal with these situations? Let’s take a look at what the auto-feeding mixer truck manufacturers say?

We concrete spraying machine is a pumping wet spraying machine, which has the characteristics of high pumping pressure, long conveying distance, low resilience, high construction efficiency, and continuous adjustment of the shotcrete amount and the addition amount of accelerator.

Wet shotcreting machine is a kind of wet shotcreting machine used in the mine field. It is an anchor and shotcrete supporting machine with good comprehensive performance at home and abroad, such as reducing dust, reducing rebound, and saving materials. It is used in mines, culverts, and construction foundation pits. It is widely used in fields such as river slope protection. It is a product with strong comprehensive performance and a very important kind of mining equipment.

At present, small wet concrete spray trucks are widely used in many fields. There are many manufacturers of small wet spray carts with different prices.
