Embodiment Construction

[0028] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0029] A piston seal, comprising a seal body 64, an annular protruding sealing strip 61 is provided under the seal body 64, and a slot 62 is provided on the sealing strip 61 to disconnect the sealing strip 61. Slot 62 is perpendicular to sealing strip 61, and slot 62 is as figure 1 or figure 2 shown.

[0030] During use, due to the harsh working environment and high temperature and high pressure of the piston, the concrete piston will deform in the cylinder under the influence of pressure. The top of the concrete piston is in contact with the concrete, the bottom is connected with the connecting rod and the cavity, and the top end pushes the concrete. It can play a good sealing effect. When stretching back, the w...

Abstract

The invention relates to a piston seal part and a machining process thereof, and belongs to the technical field of pistons. The piston seal part comprises a seal part body, an annular protruding sealstrip is arranged below the seal part body, an open groove for breaking the seal strip is arranged on the seal strip, the open groove is perpendicular to the seal strip, through the open groove, the problem that on the market, a concrete pump truck is small in feeding capacity is solved, the pumping capacity is increased, frequent replacing of a concrete piston of the concrete pump truck can be reduced, the aims of reducing cost, improving the efficiency and saving energy consumption can be achieved, a four-open mold and a three-open mold are combined with a vulcanizing machine to effectivelyremove harmful smoke in the vulcanization heating process, production efficiency is improved, and product quality is ensured.

Description

technical field [0001] The invention relates to a piston seal and a processing technology thereof, in particular to a concrete piston of a concrete pump truck, which belongs to the technical field of pistons. Background technique [0002] The concrete pistons of existing concrete pump trucks in the market have simple process and design defects. The pistons of traditional materials cannot adapt to the harsh use environment of concrete pump trucks, resulting in rapid failure in the cylinder during use. Frequent replacement of concrete pistons has a negative impact on work efficiency. It has a great impact, but also increases the cost of use and wastes a lot of time. [0003] Furthermore, the concrete piston will produce harmful smoke during the vulcanization and heating process, which is harmful to health. [0004] There is an urgent need to develop a new type of concrete piston that can effectively solve the problem of non-wear resistance of the traditional concrete piston, ...
