In the working process of the fine stone concrete pump, if the use is not standardized, it is easy to cause premature damage to some parts of the equipment, which not only increases the maintenance cost of the equipment, but also seriously affects the construction progress. Then, how to improve the service life of the vulnerable parts of the fine stone pump has become a problem that we need to pay attention to.

The traditional spraying support technology of underground space mainly relies on manual operation of spraying machine construction, spraying a certain thickness of concrete to achieve the supporting effect. In the traditional spraying environment, there are a large number of dust particles, noise pollution is also quite serious, and there is a danger of underground collapse, which poses a serious threat to the life and safety of operators in underground space construction.

The concrete delivery pump sometimes has some small faults in use, which affects safety. Through a lot of practice, Qingke Heavy Industry has discovered that in the construction process of concrete pumps and wet spraying machines, due to the influence and influence of various factors, there are a series of uncertain safety hazards. These safety hazards have an impact on the construction progress and personnel safety. And engineering cost control is a great test.

The wet shotcrete construction process is to produce finished concrete in the cement concrete mixing station according to the mix ratio. After the concrete is transported to the working surface, the concrete wet shotcrete machine is used to press it to the nozzle position, and the quick-setting agent is added to the nozzle. High-speed spraying. In the high-speed spraying process, the concrete and the accelerator are fully combined, and the concrete spray layer is formed

The double-jet hydraulic wet-jetting machine is a pumping concrete wet-jetting machine. It adopts double-nozzle spraying operation. The production capacity is 12-16 cubic meters per hour. It has the characteristics of high pumping pressure, long conveying distance, low resilience, and high construction efficiency. . Double spray hydraulic wet concrete spraying machine is widely used for wet spraying concrete machine construction operations in mines, tunnels, culverts, subways, hydropower projec

The double nozzle wet spraying machine is a new type of pumping wet concrete spraying machine, which adopts hydraulic pumping type, which has high construction efficiency, high system reliability and stable delivery volume, ensuring fast, uniform and stable spraying concrete operation.

1. Reduce the cost of use. It replaces the wear between the S valve feed port and the feed port of the cylinder with the wear between the eye plate and the cutting ring. In this way, the cost of replacing a set of eye plate and cutting ring is much lower than the cost of replacing the S valve and the material cylinder.

The fine stone concrete pump is a kind of concrete transportation equipment developed for the characteristics of floor heating construction. Because of the large-area and high-efficiency construction of the floor heating engineering filling layer or mortar filling layer, it is highly anticipated by a wide range of construction companies. So why does the fine stone concrete pump have such an effect? Now we introduce the characteristics of the major components of the fine stone concrete pump

The trailer concrete mixing pump is a very common mechanical equipment in construction. It has a smart body, easy to drag, economical and cheap, so it is welcomed by the majority of construction parties. Compared with other concrete pumps, concrete mixer with pump need to be installed in order to carry out construction during use, and certain skills need to be paid more attention to. So what problems should be paid attention to in the use of trailer concrete mixing pump?

What are the precautions in the operation of the wet spray machine? The correct use of wet spraying machines, wet spraying trolleys and other equipment will help ensure the normal progress of construction and ensure the safety of construction personnel. For example, use mortar to lubricate the concrete wet spraying machine and the feeding pipe before spraying, and rinse the remaining concrete in the pipe with water after spraying, which can effectively extend the service life.

The phenomenon of engine oil blackening is a cliché, but the blackening of hydraulic oil seems to have not been specifically mentioned. Today, the editor of the trailer concrete mixing pump will explain to you several reasons for the blackening of the hydraulic oil of trailer concrete mixer with pump mixing trailer pump:

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

The ratio of the large particle size of the coarse aggregate to the diameter of the concrete pump conveying pipe should be: when the pumping height is below 50m, it should not be greater than 1:3 for gravel, and should not be greater than 1:2.5 for pebbles; when the pumping height is 50-100m, It should be in the range of 1:3 to 1:4

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.
