Problems solved by technology

However, the hard coating is not firmly attached to the base material and is brittle, with poorer abrasion resistance and poor impact resistance, while the soft coating has low bonding strength with the base material and is easy to fall off. Although the soft coating has anti-wear and anti-cavitation performance Prominent, but it is not well combined with the base material of the parts, and it is difficult to exert its anti-wear and anti-cavitation effects

Abstract

A nano-class plastic-alloy part for hydraulic machine is prepared through proportionally mixing short aramid fibers, nanoparticles, nylon powder and PTFE powder to obtain powder mixture, proportionally mixing epoxy resin, solidifying agent and diluent to obtain slurry, mixing them together, pouring into mould containing carbon steel skeleton and aramid fiber fabric and pressure solidifying. Its advantages are high resistance to abrasion and cavitation, and low cost.

Description

technical field [0001] The invention relates to a water machine part and a preparation method thereof, in particular to a water machine nano-plastic alloy part and a preparation method thereof. Background technique [0002] The water conservancy resources that can be used in our country are quite abundant, but in recent years, due to serious soil erosion and desertification, the sediment content of the river water is large. At present, the nano-plastic alloy parts of various pumps and large and medium-sized hydropower station turbines are mostly made of stainless steel. , are subject to varying degrees of wear and cavitation damage, resulting in shortened overhaul periods for pumps and turbines, increased workload, and reduced pumping and power generation capabilities. Large, medium and small coal mines, iron mines, copper mines and other underground water pumps are more severely worn and cavitated by coal slag and iron-copper slag. Before parts with bet...
