Problems solved by technology

However, during the pumping process, the concrete cylinder will not be filled up each time the concrete is pumped, and the stroke of the oil cylinder is inconsistent each time.
The existing technology usually adopts the formula as mentioned above to calculate, or multiplies a fixed preset suction coefficient (or filling coefficient) on the basis of the above formula, and the calculation of the pumping volume is inaccurate

Abstract

The invention relates to the field of engineering machinery, and discloses a method and device for determining the pumping volume of pumping equipment and pumping equipment. The method includes: determining the effective stroke of the piston for each pumping; The effective stroke of the pumping piston and the area of ​​the concrete cylinder of the pumping equipment determine the pumping volume. Thereby, the technical problem of inaccurate calculation caused by the inability to fill the concrete cylinder with each pumping in the prior art is solved, and the accuracy of calculating the pumping volume is improved.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a method and device for determining the pumping volume of pumping equipment and the pumping equipment. Background technique [0002] At present, pumping machinery such as concrete pumps generally use hydraulically driven double-cylinder reciprocating piston pumps, which use two concrete cylinders to alternately act to push the two pistons to move and press the objects to be conveyed, such as concrete, to realize the delivery of the objects to be conveyed. continuous delivery. [0003] Pumping volume is an important data of pumping machinery, and it is an important basis for evaluating the performance of pumping machinery and checking the usage of pumping machinery. Accurate pumping volume is also an important prerequisite for automatic and unmanned distribution of pumping equipment. [0004] In the prior art, the method for determining the pumping volume is mainly determine...
