A concrete pump motor power is to determine the amount

A concrete pump motor power is to determine the amount of outlet pressure and delivery side a prerequisite under motor power in certain circumstances, increase the amount of pressure will make the delivery reduced; cheap price steel wire bending and cutting machine on the contrary, reducing the outlet pressure will make the delivery quantity increase. In order to ensure concrete pumps both have a larger throughput, but also a certain outlet pressure and the matching of economic power in the concrete pump's design, mostly using a constant power piston pump; that is constant power value Once selected, when the outlet pressure increases, the pump displacement volume is reduced automatically reach and power to design corresponding value; if necessary to achieve the outlet pressure is high, but also want the purpose of transmission capacity. The only way is to increase the motor power. Therefore, in the new national standards, citing the ability to index concept concrete pump (in MPa.m3 / h as the unit of measure); that is the actual pump delivery pressure and the amount of the actual export of concrete per hour, good product, the value, the more large, the greater its ability index, the greater the electrical power will, thus achieving large displacement, high lift purposes. Many manufacturers in the design, functional design also features high and low voltage switch to meet the different construction requirements, economic status, but also have a greater transport capacity, or in the same motor power, resulting in a higher outlet pressure . Still HBTS60-13-90 for example, when it is at maximum throughput 63m / 3h, the outlet pressure is 7.7MPa, can achieve fast pumping large displacement of low pressure, when switching to a throughput 37m3 / h, the maximum export pressure reaches 13MPa, construction steel bar bending machine supplier can achieve high-lift small displacement high pressure, long-distance transport. To concrete pump outlet pressure reaches high pressure levels, while there are large amounts of transport, in the case of insufficient electrical power, it is impossible to simultaneously achieve.See pump concrete element configurationPumpPump concrete pump is the "heart", depending on the origin of domestic and imported hydraulic pump to the other; according to the form of the structure of the hydraulic pump gear pumps, vane pumps, piston pumps division. For the same form of the hydraulic pump is adapted to different pressure levels. Gear pumps due to low cost, adaptability, early in the concrete pump is widely used, but because of the pressure is small, a large pulse resistance, usually configured on the low-pressure pump, or only in the high-pressure pump auxiliary hydraulic system; piston points swashplate and Cline, adapt its pressure range, is currently widely used. As Jiajiang Hydraulic Machinery Factory production HBTD40-6-55 type low pressure w11s stainless steel three roller nc bending machine concrete pump, main hydraulic pump on the use of German Harvey's V30D swashplate piston pump, with high-grade element configuration to enhance the quality of the machine . Imported hydraulic pump, such as Germany Rexroth A4VG, A10VG, A11VG series and Kawasaki's K3V, K5V swashplate piston pump, are world-class products and services. Domestic Cline piston pump, the hydraulic power source in Guiyang, represented A7V, A8V piston pump series products are made in China quality, quality relative *. Therefore, the use of hydraulic grade, you can spy a concrete pump overall performance of remarkable.Hydraulic valvesHydraulic pump valve is "assistant", including sequence valves, valves, valve, relief valve, check valve and switching valve. Domestic valve, unloading valve with Shanghai Lixin, Beijing, China and Germany product is excellent, but in order valves, valves and other technical difficulties, may * high requirements on valves, in order to use Germany Harvey, Rexroth, Eaton, Wei Geshi, Italy A drag Adams (Atos), the Japanese oil research and other world famous brands better, it will give concrete pump performance can * guarantee.
