Problems solved by technology

If a separate safety relief valve and unloading valve are installed at the outlet of the pump, the system is complicated, the design and assembly of the pipeline is difficult, and the cost is high. If it is a multi-pump parallel system, the above problems are more prominent. Among the plunger pump products, there is no report that the pump body has a pressure limiting overflow and unloading device

Abstract

The invention provides a water hydraulic axial plunger pump with a pressure limiting overflow device and an unloading device. The water hydraulic axial plunger pump comprises a rear end cover (1), a valve plate (2), a rotary cylinder body assembly (3), a shell (4), a sliding bearing (5), an odd number of plunger sliding shoe assemblies (6), a return stroke plate (7), a swash plate (8), a mechanical seal (9), a front end cover (10), a shaft (11), the pressure limiting overflow device and the unloading device. A pump body is provided with the pressure limiting overflow device and the unloading device and applied to a water hydraulic transmission and control system; and compared with the design that a pipeline and a control valve are added to a pump with the same function, the system is simple, the integration level is high, pipeline design is simple, and manufacturing cost is low. The double-damping design adopting machinery and fluid power is adopted by the pressure limiting overflow device, so that the prominent problems of the pressure limiting overflow device in the aspects of working vibration, noise, pressure adjustment precision, stability, anti-pollution capacity and the like are solved effectively.

Description

technical field [0001] The invention relates to displacement pumps, in particular to a water hydraulic axial plunger pump with a pressure limiting overflow and unloading device. Background technique [0002] In recent years, breakthroughs have been made in water hydraulic transmission and control technology that directly uses water (filtered natural water, including seawater and fresh water) instead of mineral oil as the working medium, and in a wide range of engineering applications, compared with traditional oil Hydraulic transmission has proved to have outstanding advantages such as environmental protection, cleanliness, high efficiency, convenient use and maintenance, and low operating cost. Water hydraulic transmission and control technology has been widely used in high-pressure water atomization, seawater desalination, high-pressure water cleaning, stage drive and control, submersible buoyancy adjustment system, marine engineering and other transmission and control fie...
