Should pay attention to the customers to purchase a good pump concrete pump main technical parameters, such as maximum theoretical transmitting highly theoretical pumping capacity, concrete pump maximum pressure. Theoretical pumping capacity is the theoretical parameters of the pumping system. It is under conditions of pumping concrete having the best slump, the pumping system to the suction rate of 100%, in the low pressure pumping (high or low pressure pumping mechanism switching) state pumping capacity, while the actual construction can not have the above-mentioned conditions. Actual pumping capacity and pumping concrete pressure is inversely proportional to the relationship, it depends on the following factors.Henan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years. Our main products are as follows:concrete mixers,diesel concrete mixer,etc. We will provide you with the best product and service. (1) pumping system the constant power point: the current domestic and foreign production of concrete pump, the pumping mechanism are constant power systems, high pumping pressure pumping capacity, low pressure pumping, pumping party increased to a constant power, a reasonable match to favor power and the main pump concrete pumps, can be seen from the pumping performance curve, the oil pressure of the of generally constant power curve from the transfer point in about 15 ~ 18MPa. (2) the actual construction of the inevitable downtime and intermittent time: estimate for a project should be discounted amount of conveying party, and configure the device in accordance with the pouring amount to be completed within the stipulated time, we have a good chance. Therefore the average pumping concrete square in the actual operating time to determine the amount shall be from 40% to 55% of the theoretical pumping capacity. The maximum pressure pumping concrete...
