Abstract

The invention provides a manufacturing method for integrally forming a carbon fiber composite material pump body and an impeller for a pump. The manufacturing method comprises the following steps that1, the carbon fiber material with a proper specification is prepared; 2, MgO, a curing agent, a low-shrinkage agent and a wetting dispersant are added into an epoxy vinyl resin raw material, and themixture is stirred for 2-4 h at the normal temperature and fully mixed; 3, the carbon fiber material is mixed with the mixture; 4, the temperature of a molding press is raised to a preset temperature,and a mold is preheated; 5, a mixing material is put into a preheated pump body mould pressing mold or ab impeller mould pressing mold, and mold closing is performed; and 6, the mixing material is pressurized and heated to a preset temperature, the temperature is kept, and after cooling, demolding is performed. According to the method, the complexity of the forming process of the carbon fiber composite material pump body and the impeller for the pump is greatly reduced, integral forming is achieved, the problems of gluing and bolt fastening connection are solved, the structural strength of the pump body and the impeller is enhanced, the problems of low structural strength, pressure-bearing deformation, cracking, leakage and the like are solved, the manufacturing process is simple, the cost is low, and the application prospect is wide.

Description

technical field [0001] The invention relates to a manufacturing method for integrally forming a carbon fiber composite material pump body and an impeller for a pump. Background technique [0002] The pump is a general-purpose machine with many types and wide applications. At present, the pumps used on ships and high-speed railways are generally made of metal. Metal pumps have problems such as large vibration, high noise, and relatively heavy weight. The requirements for pumps used on ships and high-speed rail are high strength, low vibration, low noise, and the lighter the weight, the better. [0003] The carbon fiber composite material pump just meets the requirements of high strength, low vibration, low noise and light weight. The main components of the carbon fiber composite pump, the pump body and the impeller, are made of carbon fiber composite materials, which are key components for improving strength, reducing vibration and noise, and reducing weight. At present, t...
