Qualitative and quantitative analysis should be uniform, mutually complementary; qualitative analysis and quantitative analysis of the basic premise of the hydraulic motor repair, there is no qualitative and quantitative is a blind, worthless quantitative; qualitative and quantitative analysis to make it more scientific, accurate, it can cause extensive and in-depth qualitative analysis of the conclusions drawn. Quantitative analysis is based on statistical data, a mathematical model of the hydraulic motor maintenance, and use of a mathematical model to analyze the object of the indicators and their values. CY14⑴B series pump is to take the cylinder is rotated by the variable head (swash plate) variable axial piston pump. Because between the shoe and the variable head, took a hydrostatic equilibrium of the best design of the hydraulic motor repair oil film thickness between the valve plate and cylinder block, so that is a pure liquid friction operation between the two pairs of sports surfaces, and eliminating the need for heavy-duty thrust bearings, as compared with other types of pumps, it has a simple structure, small size, high effectiveness, light weight, low noise, long life, strong self-absorption capacity, etc., it is suitable for forging machinery, machine tools, marine, aviation, metallurgical machinery, plastics machinery, engineering machinery and mining machinery, such as hydraulic equipment. The hydraulic motor parts _ crystal create hydraulic price (certification) _ hydraulic motor from Jinan Jing Chong Hydraulic Machinery Limited. Jinan Jing Chong Hydraulic Machinery Co., Ltd. (www.jnjcyy.com) (www.jnjcyy.com) Shandong Jinan, mining machinery leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum meet customer needs. In the crystal creating hydraulic leadership with the staff warmly welcome all inquiries negotiations to create the crystal creating hydraulic better future.
