Abstract

The invention provides a concrete piston, a pumping device and pumping equipment. The concrete piston comprises a piston body and first clamping cloth. The first clamping cloth wraps the outer side face of the piston body in the circumferential direction; the first clamping cloth comprises a plurality of clamping cloth layers, the clamping cloth layers comprise woven cloth, the woven cloth comprises first woven lines and second woven lines which are arranged in a crossed mode, and the included angle alpha formed by the first woven lines and / or the second woven lines on at least one clamping cloth layer relative to the radial plane where the piston body is located is larger than 0 degree and smaller than 90 degrees. Based on the optimal design of the arrangement structure of the braided wires in the cloth clamping layer, the braided wires can well conduct stress on tearing force borne by the cloth clamping layer and effectively disperse the tearing force, the stress balance and structural stability of the cloth clamping layer are ensured, the anti-tearing strength between the first cloth clamping layer and the second cloth clamping layer is improved, and the service life of the first cloth clamping layer is prolonged. And the effective service life of the concrete piston is ensured.

Description

technical field [0001] The invention relates to the technical field of concrete pistons, in particular to a concrete piston, a pumping device and pumping equipment. Background technique [0002] As a kind of sealing and power equipment, the concrete piston mainly pumps the cement slurry to high places and distant places by reciprocating in the cement slurry and other media, and at the same time, based on the sealing effect, the cement slurry is prevented from leaking. Therefore, concrete pistons are widely used in towed concrete pumps, truck-mounted concrete pumps and concrete pump truck pumping systems, and are also one of the main wearing parts of pumping devices. [0003] The existing concrete piston mainly includes a piston body and an interlayer covering the side surface of the piston body in the circumferential direction. Because the wear of the concrete piston mainly occurs on its side, the structural design of the existing interlayer is unreasonable, and it cannot b...
