Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing:

[0020] The present invention adopts the mixed design of the oil pressure element and the water pressure element, and is composed of the oil pressure element, the water pressure element and the mechanical mechanism. It is suitable for hydraulic pump structure as transmission medium. Also suitable as an energy transmission hydraulic pump structure. The structure controls the hydraulic cylinder through the hydraulic element, so that the hydraulic cylinder reciprocates to realize water absorption and drainage, and realizes the function of the hydraulic variable pump.

[0021] 1. Connection relationship through the oil circuit: the input end of the hydraulic pump 1 is connected to the oil tank 25 through the oil inlet 30 of the pipeline, and the output end is connected to the high-speed proportional directional flow valve 4 through the pipeline; the high-speed proportional dire...

Abstract

The invention provides a water pressure variable pump, belongs to the technical field of water pressure proportional control, and can effectively realize the effects of proportional flow of a water pressure pump, pressure control, low-pressure unloading and the like. An oil pressure element and a water pressure element are adopted for a mixed design; the oil pressure element and the water pressure element are respectively connected by pipelines; the oil pressure element and the water pressure element are connected into a whole by a mechanical connecting rod structure; the oil pressure element is driven by a motor to control a water pressure cylinder; and an oil pressure actuator is controlled to enable a mechanical structure to move, so that the water pressure cylinder can do reciprocating motion to realize water absorption and water drainage, and the proportional precise control function of the water pressure variable pump can be realized. The invention is mainly used for a transmission medium water pressure pump structure and an energy transmission water pressure pump structure.

Description

technical field [0001] The invention belongs to the technical field of water pressure control, in particular to the technology with proportional control of water pressure. Background technique [0002] Modern hydraulic technology is mainly an environmentally friendly new type of hydraulic drive technology based on tap water or seawater medium. There are more and more extensive demands in the fields of pharmaceutical manufacturing, food processing, deep-sea resource exploration, and high-pressure water washing. The principle of water pressure technology is similar to that of oil pressure technology, but due to the special physical and chemical characteristics of water compared with oil, such as low viscosity, corrosiveness, high saturated vapor pressure, etc., it causes serious leakage, friction, wear, corrosion, and cavitation Problems such as these make the development of modern hydraulic components involve technical difficulties in many aspects such as new materials, new ...
