What are the working principles of the concrete mixing pump?The first is to load the material, get the material into the mixing tank, the mixing tank is driven by the motor to operate, and the mixed concrete is poured into the material bucket. The material in the hopper must enter the conveying cylinder. The conveying system is powered by the hydraulic system. The conveying cylinder is pushed through the oil cylinder, and the concrete is sucked and sent one by one. Concrete mixing tractor is composed of concrete mixing and pumping professional equipment.Apr 8,2020- Summer maintenance method of concrete pump and engineIn the hot summer, the outdoor temperature on the construction site often exceeds 40 degrees. The long-term construction will cause the engine of the pump truck to heat up and the temperature of the hydraulic oil will rise, and the hot heat will further exacerbate the temperature of the engine and the hydraulic oil. So, what measures should we take to maintain the pump truck and its engine in the hot summer?Apr 8,2020
- Main technical parameters of small concrete pumpThe small concrete pumping pressure value has two values of high pressure and low pressure. When the main hydraulic cylinder is driven without a rod cavity, the corresponding outlet pressure is high pressure; when the small concrete pump main hydraulic cylinder is driven by a rod cavity, the corresponding outlet pressure is low pressure.Apr 8,2020
- Fine stone concrete pump requirements for cement pumping processThe function of fine stone concrete pump on cement in the pumping process: The pumping pressure of concrete is transmitted by the liquid phase substance in it. The liquid phase material carries the solid phase material and moves together to complete the pumping. There are two aspects of the role of cement. One is the cementation effect, which enables the concrete to maintain the state of solid phase material surrounded by liquid phase material during pumping;Apr 3,2020
- Application of wet concrete shotcrete machine technology in tunnel construction (1)With the continuous progress of the production technology of wet concrete spraying machinery and related materials and equipment, wet sprayed concrete will be widely used as a mature construction method.Apr 3,2020
1. Overview of sprayed concrete technology
1.1 Sprayed concrete process principle and characteristics - Application of wet concrete shotcrete machine spraying machine technology in tunnel construction (2)Technical points of wet spraying operationApr 3,2020
(1) When concrete is mixed in the order of sand → crushed stone → cement → water, full-automatic metering force mixer is used for mixing, and the construction ingredients are strictly operated according to the mixing ratio; after adding the compound pumping agent, the mixing is performed for more than 2 minutes. Over 4 minutes, so as not to affect the quality of the concrete. - How to design delivery pipe lines for concrete pumpFirst of all, the conveying pipe of the concrete conveying pump needs to be piped according to the characteristics of the project and the construction site and the concrete pouring scheme. Minimize the use of bends and hoses. The laying of the conveying pipe should follow safe construction, which is convenient for cleaning the pipeline, troubleshooting and repair in principle.Apr 3,2020
- Fine stone concrete pump repair and maintenance knowledge tipsWith the development of the construction industry in northern China in recent years, floor heating has become a necessary facility for building construction. This also greatly promotes the use of fine stone concrete pumps. The fine stone concrete pump can not only improve work efficiency, but also help reduce the labor intensity of workers. People use fine stone concrete pumps at the same time as they start to rely on the fine stone concrete pumps. If the fine stone concrete pumps fail duringApr 1,2020
- Differences between trailer concrete pump and truck mounted boom concrete pump"Concrete delivery pump" and "concrete delivery pump truck" are both concrete delivery machinery. They are used in the same way, except that the former needs to be transported by a truck and requires additional support pipes, while the latter is a locomotive body with freely extending booms, no pipes are needed. And the latter is much more expensive than the former, the former needs hundreds of thousands, and the latter needs millions.Apr 1,2020
- Saintyol DAWIN Machinery tells you the safe operating rules of hydraulic concrete wet spraying machineHow to operate a hydraulic concrete wet spray machine? What are the precautions for safe operation of hydraulic concrete wet sprayer? The Saintyol DAWIN Machinery wet concrete spray machine manufacturer introduces the safe operating rules of hydraulic concrete wet spray machine. I hope it will be helpful for everyone to operate the wet spray machine.Apr 1,2020
- How to use wet sprayer wet concrete spraying machine?First, the preparation work of the hydraulic wet concrete spraying machine before startingMar 31,2020
1. First, fix the hydraulic wet concrete spraying machine on a solid foundation. The spraying pipe must be reinforced and the pipeline must be installed properly without leakage.
2. Connect the three-phase power supply and check the lubricating oil level. - Saintyol DAWIN Machinery Mini Class Mobile Concrete Mixing PumpThe towing concrete mixing pump is a small concrete conveying pump that integrates loading, mixing, and high-pressure pumping with a fully automated construction operating system. The pump is simple to operate, stable in performance and easy to move.Mar 30,2020
