Rotary disc for plunger pumps, processing method of rotary plate and injection mold

Abstract

The invention discloses a rotary disc for plunger pumps, a processing method of the rotary disc and an injection mold. The rotating disc for the plunger pump comprises a friction surface piece, multiple plunger sleeves, a rotating shaft and a disc body, wherein the plunger sleeves are mounted on the disc body, the multiple plunger sleeves are uniformly arranged around the rotating shaft, the radial direction of the disc body is perpendicular to the axial direction of the rotating shaft, and the disc body is made of plastic; and the friction surface piece, the plunger sleeves and the rotating shaft are integrated, the friction surface piece is made of alloy steel, the rotating shaft is made of alloy steel, and the plunger sleeves are made of copper alloy. By adopting the structure, the volume can be reduced, the flow is increased, and the weight of the whole rotating disc can be effectively reduced by adopting the disc body made of the plastic materials in the rotating discs for the plunger pumps. By means of the disc body made of the plastic materials, the friction surface piece, the plunger sleeves and the rotating shaft are fused into a whole, and the machining cost of the wholerotating disc is reduced; and more suitable materials are used for making the friction surface piece, the plunger sleeves and the rotating shaft, so that the service life of the rotating disc is prolonged.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of high-pressure cleaners, and in particular to a rotary disk for a plunger pump, a processing method thereof, and an injection mold. Background technique [0002] The cleaning machine is driven by a motor to drive the pump body to move, transforming the static water into a high-speed water jet. The cleaning machine can be used for car washing, floor washing, etc., because it is small and easy to carry, so It is widely used in life. [0003] At present, the washing machine on the market is driven by the motor to rotate the swash plate. The plunger on the plunger pump for pumping water is always in contact with the swash plate through the spring, and the swash plate is installed on the rotating shaft. The diameter of the swash plate The angle between the axial direction and the axial direction of the rotating shaft is an acute angle, but this structure is unstable, the volume is rel...
