Embodiment 1

[0048] Step 1: The distribution of raw materials for pump components:

[0049]

[0050] Ultra-high molecular weight polyethylene 65.5Kg, the molecular weight of the ultra-high molecular weight polyethylene is greater than 1.5 million. Described filler is made of glass fiber, glass microsphere powder, Al 2 o 3 , carbon fiber, graphene, and NdFeB powder are composed of 1:1:1:0.5:1:2 by quality and quantity;

[0051] Described lubricant is molybdenum disulfide;

[0052] Step 2 Preparation of Spectacle Plates

[0053] The spectacle plate is prepared by injection molding the raw materials prepared in the first step.

Embodiment 2

[0055] In this embodiment, the prepared raw material is made into a tubular shape, and then cut into shape to prepare a standard cutting ring and a replacement cutting ring. The replacement cutting ring is 5 cm longer than the standard cutting ring. Wherein the distribution of raw materials is completely consistent with Example 1.

Embodiment 3

[0057] The preparation of raw materials for the pump components is exactly the same as that in Example 1, except that the S-shaped tube is prepared by injection molding in this example; the pressure resistance of the obtained S-shaped tube can reach 50 MPa. When assembling, fix the rocker shaft on the outer wall of the S-shaped tube.

Abstract

The invention relates to a part for a pump, a replacement method and an application thereof, particularly relates to a spectacle plate, a cutting ring and an S-shaped pipe of an S-shaped pipe valve for the pump, a replacement method and an application thereof and belongs to the technical field of development of concrete pump trucks. The part for the pump contains polyethylene with ultrahigh molecular weight. The part is used for conveying and spraying concrete, coal slurry, other thick slurry residues and fire-fighting water. Compared with the existing spectacle plate with a steel substrate and an overlaying wear-resistant layer, the spectacle plate designed by the invention is 3-5 times larger than the existing spectacle plate, and when the spectacle plate designed by the invention is matched with the cutting ring for use, the pumping life of the pump reaches 100,000 cubic meters. Simultaneously, the polyethylene with the ultrahigh molecular weight is nonstick to mediums such as concrete, is convenient in cleaning, is non-corrosive and is easy in maintenance and replacement. The part designed by the invention is long in service life, simple in replacement, low in production cost, easy in control of production accuracy and convenient in large-scale industrial application.

Description

technical field [0001] The invention relates to a pump component and its replacement method and application; in particular, it relates to a pump spectacle plate, a cutting ring, an S-shaped pipe of an S-shaped pipe valve, its replacement method and its application, and belongs to the technical field of special pump development. The special pump truck includes a concrete pump and a high-pressure fire pump. Background technique [0002] Spectacle plate is also called wear plate, which is an important part of concrete pump. The cutting ring is also called the wear ring, and it is also an important part of the concrete pump. The cutting ring and the spectacle plate form a switching friction pair. When the concrete pump is working, due to the rapid swing of the cutting ring, it will have strong friction with the spectacle plate, which will cause the spectacle plate to be easily worn out. At the same time, the spectacle plate works and bears the specific impact force and shear ...
