Changing the hydraulic oil into the oil channels

Piston end of the cylinder chamber communicates end chamber of the piston into the oil chamber, into the oil chamber as the larger, the oil supply is constant, will lead to slow piston speed, stroke frequency is reduced, thus reducing the displacement of the concrete. However, since the cross-sectional area into the oil chamber and the concrete pump cylinder Screw Conveyor area ratio increases, so concrete pumping pressure increased, ie Figure 3-14 piping connections, enabling small displacement high pressure pump.Modern piston concrete pump, in order to meet the needs, concrete mixing machine a high and low voltage conversion function. Its conversion, usually hydraulic drive change, that is to change the hydraulic oil supply means to achieve high or low pressure pumping.

Unit of time the volume of concrete transport

The calculation methods are mainly the following three: a. Energy conservation principles calculations mentioned in the given concrete pump power, the amount of concrete and concrete pumping pressure is the product of a certain value
Cement silo, necessarily much higher than the actual throughput of concrete. b. according to concrete delivery cylinder volume and piston velocity calculation conveying capacity can also be used concrete pump piston cylinder volume and calculated as the product. c. according to the amount of concrete hydraulic oil can also be calculated according to the following formula to calculate the hydraulic oil. d. concrete pump discharge amount of fuel, the engine power relations conveying capacity and engine power, concrete batching plant. concrete cylinder diameter, piston speed is proportional. Conveying capacity and pumping distance, pumping pressure is inversely proportional to the hydraulic cylinder diameter, etc.

Concrete pump trapped with constant power regulation

It is a measure of the ability of a concrete pumping integrated indicators, but also concrete pump main basis for classification.
① same power different concrete pump, its pumping capacity index identical; ② in concrete pumping pressure is constant, the amount of concrete surface increases with the increase of power; ③ In the dynamic power is fixed, with the pressure pumping concrete increases, the amount of concrete mixing machine, and vice versa.Concrete Mixing Truck trapped with constant power regulation, so concrete pump working pressure of the outlet end of pumping concrete and concrete product of the actual maximum throughput is a certain value, this value is called the pumping capacity index, denoted by M.

Pumping concrete traits

Delivery pressure (transport distance) relationship shown in Figure 3-12. When the displacement increases, the output of the pressure drop, but also reduced the distance is output; Conversely, if the displacement is reduced, the delivery pressure increases, the transmission steel cement silo. In construction machinery, most mechanical properties can be from the production plant to provide product samples or technical specifications and other data found, they are listed in performance, mostly in line with the actual use. Wheel Loader  concrete pump, production performance provided by the Antiquities China, mostly theoretical value or maximum value, a larger difference compared with the actual use of the reason, as the actual performance with its pumped medium, pumping concrete traits, use of the environment, equipment, pipeline installation and layout and the use of manipulation associated with it.

Concrete used large displacement pump

Generally used in the pump pressure of the concrete 9 ~ 13MPa, large displacement of the pump up to 15 ~ 22MPa, pushing the piston hydraulic system pressure is generally rated pressure of 1/3. Concrete mixer delivery pressure pushes the piston depends on the ability and the total resistance of the pipeline, the two also determines the size of the pump conveying distance. Ability to push the piston structure itself is determined by the prime mover. General model to determine the pump size can not be changed later. Determined by the total resistance of the pipeline has a lot of factors, such as concrete gradation has been described previously. Under normal concrete mixing machine,  the most influential design of piping, such as the transmission distance of the horizontal or vertical, the number of straight pipe, elbow, conical tubes and hoses. So be careful in the construction designs are arranged.

Disable clay bricks

Concrete Mixing Truck departments have promulgated regulations expressly prohibit traditional clay brick 170 major cities in the country to use, and as early as 2004 years ago in the national capital city Disable All clay bricks, and increase efforts to support the production of new wall enterprises. Unburned and new compared to traditional brick in compressive strength, stiffness, energy saving aspects of the wide gap, and unburned in appearance and practicality advantages, unlike the red brick walls, like when need to soak, concrete mixing machine.  Thus, the production of unburned Mianshaozhuanji already widely across the country to replace the traditional clay bricks, creating a new type of hollow brick renewal and a new revolution in the market.

Clay brick continue

 In order to protect the limited land resources for future generations to remain a blue sky, state and local government introduced a number of policies, is strictly prohibited traditional wall concrete mixing machine bricks continued use. Each one is a block building built unburned stacked, clay brick fade triggering a revolution, a revolution of hollow bricks and unburned, opportunities and challenges of a revolution, a revolution of wealth. In addition, China has abundant coal ash and other industrial waste resources, so that opened a brick-making factory, as a bright line with policy-oriented investment, but also benefits the country's wise exclusive variety Wheel Loader and exempt from tax and other concessions.
