Problems solved by technology

As a quantitative pump, the speed of the oil pump is proportional to the speed of the engine, so the output flow of the oil pump is proportional to the speed of the engine. Obviously, when the speed of the engine is too high, the output of the oil pump must be greater than the amount of oil required by the system, resulting in great waste
In order to solve this problem, the pressure plate and side plate of the two high-pressure areas need to be loaded separately, but the pressure plate and side plate of the existing oil pump cannot be loaded separately

Embodiment Construction

[0012] Examples, see attached Figure 1-3 The pressure plate and the side plate respectively loaded on the two high-pressure areas of the double-acting vane pump are symmetrically arranged at 180 degrees on the upper outer edge of the front of the pressure plate 1, and the oil outlet of the pressure plate 1-1 and the oil outlet of the pressure plate are provided. Two 1-2. The edge of pressure plate 1 between the head and tail of pressure plate oil outlet 1-1 and pressure plate oil outlet 2 1-2 is symmetrically provided with fan-shaped pressure plate oil suction window 1-9 and pressure plate oil suction window 2 1- 10. Out of the center hole of the pressure plate 1, there are circular pressure plate oil passage grooves 1-5, pressure plate oil passage grooves 2 1-8, pressure plate oil passage grooves 3 1-6 and pressure plate oil passage grooves 4 arranged symmetrically at 90 degrees outside the central hole of the pressure plate 1. 1-7. Pressure plate oil passage groove one 1...

Abstract

The invention belongs to hydraulic components in mechanical industries, and particularly relates to a pressure plate and a side plate respectively loaded to two high-pressure areas of a double-actingvane pump. A pressure plate oil outlet I and a pressure plate oil outlet II are symmetrically formed at a 180-degree angle in the front of the pressure plate. A pressure plate oil suction window I anda pressure plate oil suction window II are symmetrically arranged at the edge of the pressure plate between heads and tails of the pressure plate oil outlet I and the pressure plate oil outlet II. The included angle between heads and tails of a pressure plate oil through groove I and a pressure plate oil through groove IV and a pressure plate oil through groove II and a pressure plate oil throughgroove III is alpha. The tangent line across the circle center at the beginning of the pressure plate oil through groove I and the connection line of the starting edge of the pressure plate oil suction window II and the circle center form a theta angle. The two oil outlets in the pressure plate in the pressure plate and the side plate loaded to the two high-pressure areas of the double-acting vane pump can be completely loaded independently so that the double-acting vane pump can realize two independent double pump functions.

Description

technical field [0001] The invention belongs to hydraulic components in the machinery industry, in particular to a pressure plate and a side plate that load two high-pressure areas of a double-acting vane pump respectively. Background technique [0002] At present, due to its compact structure and low noise, double-acting vane pumps have been widely used in automobile steering systems and gearbox systems. As a quantitative pump, the speed of the oil pump is proportional to the speed of the engine, so the output flow of the oil pump is proportional to the speed of the engine. Obviously, when the speed of the engine is too high, the output of the oil pump must be greater than the amount of oil required by the system, resulting in great waste . In order to solve this problem, the pressure plate and the side plate of the two high-pressure regions need to be loaded separately, but the pressure plate and the side plate of the existing oil pump cannot be loaded separately.
