Embodiment 1

[0044] First, the carbon fiber is woven into a three-dimensional braided carbon fiber through three-dimensional all-five-way blending, and the braiding angle is 12 degrees.

[0045]Then, the three-dimensional braided carbon fiber with a volume percentage of 15% is fixed in a cylindrical mold with a temperature of 250°C, and then poured into a molten metal with a volume percentage of 85% aluminum alloy at a temperature of 665°C and pressurized. The pressure is 90MPa, the pressure building time is 2s, and the pressure holding time is 8s, and the semi-finished column is obtained. Wherein, the aluminum alloy is composed of the following mass percentage components: Mg: 5.5%, Zr: 0.1%, Sc: 0.3%, and the balance is Al and unavoidable miscellaneous elements. Then the semi-finished column is subjected to heat treatment. The heat treatment includes solution treatment at 510° C. for 45 minutes, and then aging treatment at 300° C. for 60 minutes to obtain the final finished column.

The pressure is 90MPa, the pressure building time is 2s, and the pressure holding time is 8s, and the semi-finished column is obtained. Among them, the aluminum alloy is composed of the following mass percentage components: Mg: 5.5%, Zr: 0.1%, Sc: 0.3%, Mn: 0.1%, Cr: 0.1%, Ti: 0.03%, the balance is Al and unavoidable impurities element. Then the semi-finished column is subjected to heat treatment. The heat treatment includes solution treatment at 510° C. for 45 minutes, and then aging treatment at 300° C. for 60 minutes to obtain the f...

Embodiment 3

[0050] First, the carbon fiber is woven into a three-dimensional braided carbon fiber through three-dimensional all-five-way blending, and the braiding angle is 12 degrees.

[0051] Then, the three-dimensional braided carbon fiber with a volume percentage of 15% is fixed in a cylindrical mold with a temperature of 250°C, and then poured into a molten metal with a volume percentage of 85% aluminum alloy at a temperature of 665°C and pressurized. The pressure is 90MPa, the pressure building time is 2s, and the pressure holding time is 8s, and the semi-finished column is obtained. Among them, the aluminum alloy is composed of the following mass percentage components: Mg: 5.8%, Zr: 0.05%, Sc: 0.25%, Mn: 0.2%, Cr: 0.1%, Ti: 0.05%, the balance is Al and unavoidable impurities element. Then the semi-finished column is subjected to heat treatment. The heat treatment includes solution treatment at 510° C. for 45 minutes, and then aging treatment at 300° C. for 60 minutes to obtain the...

Abstract

The invention relates to an aluminum cast pump body. The aluminum cast pump body comprises a base and a column body. The base is square. A circular convex edge is arranged on the lower surface of the base, and four first shaft holes are formed in the middle portion of the circular convex edge; and the circular convex edge is connected with the four corners of the square base through four evenly-distributed connecting strips, and a semicircular notch is formed in the position of the midpoint of one side of the base. The column body is fixedly connected to the upper surface of the base, the upper surface of the column body is in an inverted T shape, and a semicircular groove is formed in the middle portion of the upper surface of the column body; and six second shaft holes are formed around the semicircular groove and stretch to the middle portion of the column body, and the structure is simple. The base and the column body of the aluminum cast pump body are both made of a three-dimensional braided fiber / aluminum alloy composite material, so that the size, mass and cost of the aluminum cast pump body are reduced, the comprehensiveness of the aluminum cast pump body is improved, and installation and maintenance are convenient; and during use, the aluminum cast pump body is low in noise, long in suction head lift and long in service life.

Description

technical field [0001] The invention relates to the field of a hydraulic system power device, in particular to an aluminum casting pump body. Background technique [0002] The pump plays an important role in the industrial system, especially in the liquid medium supply system, and its left and right are irreplaceable. The operating performance and service time of the pump directly affect the quality level of the entire system.
