Embodiment Construction

[0025] exist figure 1 , figure 2 , image 3 and Figure 4 In the schematic diagram of the friction pair of the slipper shoe of the high-pressure seawater axial piston pump with bionic non-smooth surface, 144 through-hole units with a diameter of 1.2mm are arranged on the swash plate, and these through-hole units are regularly arranged in On the swash plate, it is distributed in a circular array, that is, the axes of these through-hole units are distributed on 6 concentric circles from the center of the swash plate to the periphery. The diameters of these 6 circles are 76mm, 88mm, 100mm, 112mm, 124mm, 136mm. In addition, 24 through-hole units on each concentric circle are evenly distributed in the circumferential direction. On the opposite side of the friction surface of the swash plate, the through-hole units are all arranged in a regularly arranged concave water tank. The width of the water tank is 2mm and the depth is 1mm. The circular array distribution of the through-...

Abstract

The invention discloses a sliding-shoe friction pair of a high-pressure seawater axial plunger pump with a bionic non-smooth surface. The sliding-shoe friction pair is mainly characterized in that through hole unit bodies are arranged on an inclined disc regularly; the through hole unit bodies are respectively arranged in inwards-concave water grooves which are regularly arranged; and the water grooves are mutually communicated. Preferably, pit unit bodies are regularly arranged on the sliding-shoe friction surface matched with the inclined disc. The sliding-shoe friction pair disclosed by the invention has the advantages that the lubricating capability, the bearing characteristic and the friction and wear properties of the sliding-shoe friction pair in the lubricating environment of seawater and under the condition of high speed and heavy load can be reasonably improved by high cost performance.

Description

[0001] Field [0002] The invention relates to a high-pressure seawater axial plunger pump, in particular to a sliding shoe / swash plate friction pair. Background technique [0003] The high-pressure seawater axial piston pump is the core power component of seawater hydraulic transmission and reverse osmosis seawater desalination and other systems with seawater as the medium. The sliding shoe friction pair composed of the sliding shoe / swash plate is one of the key friction pairs in the high-pressure seawater axial piston pump. The swash plate is a disc with a central through hole, and its outer peripheral surface is a truncated cone surface. The diameter of the central through hole is divided into three sections, the diameter of the middle section is smaller than the diameter of the two ends, and the diameters of the two ends are equal. The side of the large diameter of the swash plate, that is, the side of the friction surface of the swash plate, is opposite to the friction s...
