Inclined shaft piston pump
Introduction to inclined shaft piston pump
The inclined-axis piston pump is widely used in hydraulic systems with high working pressure, large flow and need to be adjusted due to its compact plunger structure, high working pressure, high efficiency, and easy to realize variables. In the late 1980s and early 1990s, many research institutes and manufacturers began to research and develop such products, but no substantial progress has been made. Mainly because of the need to deepen in theory, in the actual production can not solve the problem of the two pairs of friction pairs of the rotor and the distribution shaft, the sliding shoe and the stator. Some manufacturers overcome the burning process by casting the bearing alloy in the inner hole of the plunger, but the effect is not satisfactory. This method is used in a small displacement pump, although it can prevent the problem of friction pair burning, but the use of the pump Life is not long. After years of research and development, Professor Lu Bingjun and his research team, well-known hydraulic experts in China, have obtained “overbalanced pressure compensation method and double-row axial piston pump” and “a new type of high pressure Displacement axial piston pump" two technical patents, "alloy austenite-bainite ductile iron development and application research" a national new material technology achievements. The achievement of these technological achievements has made breakthroughs in the design theory and material technology of the development of radial piston pumps in China. Supported by the above two patents and a new material technology, Lanzhou Yongxin Technology Co., Ltd. successfully developed and produced the JBP series electromechanically controlled radial piston pump, which is the “Eighth Five-Year Plan” and national technology of the Ministry of Science and Technology. Torch Program Project. The pump has been in industrial testing for 2-3 years in a number of companies with excellent performance. The technical development of the plunger pump, like the development of other industries, is driven by market demand. In today's society, development is advancing with each passing day. Under the background of the high demand for high-tech development in the fields of environmental protection and electronics, and the world's sustainable development, many industries or fields including the pump industry have brought The rapid changes and development of technology. With the development of related technologies such as electronics, computers, materials, manufacturing, etc., the multidisciplinary application of axial piston pumps has made simulation and testing more realistic, and the efficiency of axial piston pump design and optimization has been greatly improved. The vitality of a product lies in the needs of the market. Today's market demand is demanding innovation and making a difference; it is this that has created a diversified trend in pump products.
Its diversity is mainly reflected in:
1. The diversity of the transport medium;
2. Differences in product structure;
3. The difference in operational requirements.
From the point of view of the transport medium, the earliest pump is transported to a single water and other flowable liquids, gases or slurries. Now it can transport solid-liquid mixtures, gas-liquid mixtures, solid-liquid mixtures until transporting live objects such as potatoes. , fish, etc. Different transport objects have different internal structural requirements for the pump. In addition to the different requirements of the transport object on the structure of the pump, new requirements are imposed on the internal or external structure of the pump in terms of the installation form of the pump, the layout of the pipeline, maintenance and repair. At the same time, each manufacturer has added the concept of their own company in the design of the structure, which has further improved the diversification of the pump structure.
