Problems solved by technology

However, during the pumping process, the concrete cylinder will not be filled up every time the concrete is pumped, and the stroke of the oil cylinder is inconsistent each time.
The existing technology usually adopts the above-mentioned formula 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 the pumping equipment. The method comprises the steps that the effective stroke of a piston during pumping each time is determined; and the pumping volume is determined on the basis of the effective stroke of the piston during pumping each time and the concrete cylinder area of the pumping equipment. Therefore, the technical problem that calculation is inaccurate due to the fact that a concrete cylinder cannot be fully filled during pumping each time in the prior art is solved, and the calculating accuracy of the pumping volume is improved.

Description

technical field [0001] The present invention relates to the field of construction machinery, in particular to a method and device for determining the pumping volume of pumping equipment and 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 dete...
