The results of two studies of design solutions gate devices: proposed new and one of the most widely used - S-shaped.
The dependence to determine the average velocity of the flow through the concrete mixture studied gate devices grounded efficiency of pump with a new design of the device.
Purpose.The purpose of research is to improve the efficiency two-piston concrete pumps with hydraulic drive as a result of studying the mechanism of movement of the concrete mix through the channels of distribution of slide units and justification advantageous sides of the structure of the new device among the existing ones.
Design/methodology/approach. There is currently no known conducting any research in the field of slide switching concrete pumps with hydraulic drive. As the results of studies on the effectiveness of the concrete pumps with hydraulic impact design features slide switching. To confirm this hypothesis were analyzed two schemes slide switching: a new constructive solution of gate devices and the famous S-shaped. If the concrete mix, passing through the gate device on the channel, on the one hand, is in contact with the metal wall and the other side - with the concrete mixture, the difference should be taken into account conditions of occurrence of shear stresses arising in the concrete layers coming from transport cylinders Concrete pump.
Findings.Analyzed two concepts slide switching concrete pumps with hydraulic drive: the proposed new and existing with different bandwidth of the channel. The dependences to determine the average speed by using different concepts crossing channels slide switching. The possibility of estimation discussed concepts slide devices from the standpoint of the effectiveness of the concrete pumps with hydraulic drive.
Originality/value.Shows the calculated and technical diagrams slide switching. An analysis of concrete pumps with hydraulic drive from the standpoint of accounting work slide switchgear and determine the average speed of concrete channels slide devicesReferences
