- Saintyol DAWIN takes you to understand the lubrication system of concrete line pumpsConcrete line pump is a kind of construction machinery. Because its working environment is relatively poor, it is more necessary to do daily maintenance and maintenance work. Among them, lubrication is a very important work. Concrete floor pumps are divided into manual lubrication and automatic lubrication. part, the specific analysis is as follows:Apr 19,2022
- Saintyol DAWIN tells you how to prevent rollover of small concrete pumps?At present, a kind of mechanical equipment that many construction parties use a lot - a small concrete pump, which greatly improves the construction efficiency. If the pump driver does not operate properly in the project, it is easy to cause the pump to roll over, which is a problem that many construction parties are very concerned about. So, how can the small concrete pump truck prevent rollover?Apr 19,2022
- Saintyol DAWIN Machinery explains several reasons why the concrete pump is blocked1 Improper operation can easily lead to blockage of the pipeApr 15,2022
1.1 The operator is inattentive
The operator of the transfer pump should concentrate on the pumping construction and always pay attention to the reading of the pumping pressure gauge. Once the reading of the pressure gauge suddenly increases, they should immediately reverse the pump for 2 to 3 strokes. . If the reverse pump has been carried out and the pump is being pumped for several operation cycles, - Safe use of concrete placing boom machine (1)In the construction site, all kinds of machinery and equipment are overwhelmed, and the safe use of concrete placing boom machine machinery and equipment is particularly important.Apr 12,2022

- Common sense of safe use of concrete pumpConcrete pumps play the role of transporters in large-scale concrete projects such as high-rise buildings, highways, and overpasses, so they are very important. For concrete pumps, the correct and safe use is equally important. In the daily operation process, how should we use the concrete pump correctly?Apr 7,2022
- Do you know what to do if the concrete pump cutting ring is worn out?The concrete pump cutting ring mainly cooperates with the rubber spring, and the gap is automatically compensated by the rubber spring and the pressure self-balance, so that the floating cutting ring has a self-sealing effect, thereby increasing the conveying pressure of the S-pipe valve. However, when the concrete pump is used for a long time, the cutting ring of the concrete pump is prone to wear.Apr 7,2022
- Concrete pump easy to block location and elimination method Saintyol DAWIN Machinery teaches youConcrete pump has now become an indispensable member of engineering construction. In addition to the promotion of urban and rural construction, its own advantages are also very obvious, reducing labor force, shortening construction period, and improving project progress efficiency. The correct use of the concrete pump can not only improve the work efficiency, but also avoid the blockage of the concrete pump.

- Requirements for concrete slump in fine stone concrete pumpingRequirements for concrete slump in fine stone concrete pumpingMar 28,2022
When the concrete with a slump of 10-15 cm is dumped into the hopper, its surface is easily broken; when the slump is less than 10 cm, the concrete is completely broken after tilting, and has a serrated edge, which breaks vertically. into thick blocks; - Requirements for Concrete Additives for Fine Stone Concrete Pump DeliveryTo improve the pumpability of concrete, it is necessary to increase the amount of cement, use a larger water-cement ratio and sand ratio, and use a stricter aggregate gradation, which means an increase in cost or a decrease in quality. A more economical and effective way is to use admixtures to improve the pumpability of concrete. There are many types of additives, among which the admixtures that can improve the pumpability of concrete include air-entraining agents,Mar 28,2022

- Maintenance of wet concrete spraying machine before useThe maintenance before and after use of the wet spraying machine requires frequent maintenance, so as to maintain its high performance, as smooth as new, reduce the number of failures, and bring greater benefits to the company. The same goes for wet sprayers. As the most advanced shotcrete support equipment in China, the concrete wet shotcrete machine has a wide range of uses, and the construction environment is also extremely complex,Mar 16,2022
- Do you know the maintenance of concrete wet spraying machine after use?The maintenance before and after use of the wet spraying machine requires frequent maintenance, so as to maintain its high performance, as smooth as new, reduce the number of failures, and bring greater benefits to the company. The same goes for wet sprayers. As the most advanced shotcrete support equipment in China, the concrete wet spraying machine has a wide range of uses and the construction environment is also very complicatedMar 16,2022
- What are the requirements for fine stone concrete pumping for cement?Requirements for Cement Conveyed by Fine Stone Concrete PumpMar 16,2022
1. Reduce the frictional resistance of the mechanical part of the concrete with the pump, the conveying pipeline and the interior of the concrete and have good fluidity. - Requirements for Concrete Aggregate Conveying by Fine Stone Concrete Pump - Part 1Fine aggregates can be divided into river sand, sea sand, mountain sand and artificial crushed sand according to their sources. The concrete using the former has better pumpability; the artificial sand has a rough surface and poor sand shape, so it is necessary to add some natural sand to improve its proportioning properties, but the artificial sand has better water retention, which can reduce the bleeding and segregation of concrete.Mar 16,2022

2. Coarse aggregate
Pumped concrete can be made of pebbles, crushed stone or a combination of pebbles and crushed stone. - Laying of the Conveying Pipe of the Pumping Wet Spray TrolleyThe laying of the delivery pipe of the pumping wet spray trolley First, whether the laying of the pipeline reasonably affects the construction efficiency and quality of the pumped concrete. The pumping pipeline generally follows the "principle of short straight line between two points", and reduces pipe bends to a great extent. And the utilization rate of the hose, when using the elbow, try to avoid the bending of the elbow is too large.Mar 7,2022
- Do these jobs well, and pumping concrete can also be very simple!If the pressure of the concrete pump is too high and unstable, and the oil temperature rises. When the conveying pipe vibrates obviously and the pumping is difficult, it is not allowed to pump forcibly, and the cause should be immediately identified and eliminated. The delivery pipe can be bent first by hitting it with a mallet. Conical pipes, etc., and pump at a slow speed or reverse pump to prevent clogging.Mar 7,2022
- Know some little knowledge about concrete pump. Concrete pump is a very commonly used concrete pump at present, and has been widely used by major construction units. In the construction process, according to the different engineering conditions and construction environment, users usually use different forms of small concrete delivery pumps.Mar 1,2022
- How to choose the right concrete pump during constructionThis scheme has the advantages of simple construction and low construction cost, but the pumping pressure of this scheme is too high, which is easy to cause leakage, leading to many problems such as concrete segregation and pipe blockage. The requirements are extremely high; at the same time, once the project is completed, the pump is not economical for other general projects.Mar 1,2022
- Do these jobs well, and pumping concrete can also be very simple!The pumped concrete should meet the pumpability requirements, and if necessary, the mix ratio of the pumped concrete should be determined through test pumping.Mar 1,2022
- How to use the concrete pump correctly during operation1. Straight line laying of pipelines: In the process of laying concrete pump pipelines, it is generally necessary to ensure that the pipeline laying lines and pouring points of the pumping equipment are straight, and the bending degree is minimized. At the same time, the laying of the concrete pump pipeline support and the fixing of the pipeline must be tight and reliable, the pipeline joints should be kept sealed and reliable, and the hose and the steel pipe should not be mixed together.Feb 14,2022
