Optional concrete pump selection of technical parameters

The choice of technical parameters for the purchase of concrete pumps: customers choose the pump should pay attention to the main technical parameters of concrete pumps, such as the maximum theoretical delivery height, the theoretical pumping capacity, the maximum pressure of pumping concrete. The theoretical pumping capacity is the theoretical parameter of the pumping system. It is the pumping capacity at which the pumping system achieves a 100% suction rate under low pressure pumping (pumping mechanism with high and low pressure switching), with the optimum slump of the pumpable concrete The actual construction can not have the above conditions. The actual pumping capacity is inversely proportional to the pumping concrete pressure and depends on the following factors. (1) Constant power point of pumping system: At present, the concrete pumps produced by domestic and foreign enterprises adopt constant power system. When the pump pressure is high, the pump capacity is low and the pumping pressure is low. Increasing the amount of power to a constant power is conducive to a reasonable match between the power and the main oil pump. From the pumping performance curve, it can be seen that the oil pressure of the general constant power curve is about 15-18 MPa. (2) The unavoidable downtime and intermittent time in the actual construction: For a project, it should be estimated according to the delivery amount converted, and it is more certain to configure the equipment according to the pouring amount to be completed within the prescribed time. Therefore, the actual working time in the average pumping concrete side should be based on the theory of pump side of the amount of 40% to 55% to determine. Pumping concrete maximum pressure refers to the concrete pumping mechanism hopper outlet can reach the concrete pressure. The purchase of concrete pump is mainly to see the price, quality, service three points, the United One in Trinity and other large enterprises of course great service, but the price is very low, due to the monopoly of concrete pump technology has been broken, many companies produce concrete pump The quality is almost comparable to the big companies such as Trinity, and the price is only a few percent, reaching a very good price, and after-sales have done quite well.
