From the viewpoint of energy conversion, the hydraulic pump and hydraulic components of the hydraulic motor is reversible work input to any one of the working liquid pump, the hydraulic motor can make it into condition; otherwise maintenance of the hydraulic pump (domestic), when the spindle of the hydraulic motor is driven to rotate by the external force moment, they can become hydraulic conditions. Because they have the same basic structural elements - a closed cycle but the volume can be varied and the corresponding dispensing means. Today, the development of the machinery industry is getting ahead of the maintenance of the hydraulic pump (made in China), and the hydraulic industry also will be vacated born. Hydraulic pump hydraulic system hydraulic power units service (domestic), whose role is the original motivation of the mechanical energy into fluid pressure energy, refers to the hydraulic system of pumps, which provides power to the entire hydraulic system. The general structure hydraulic gear pumps, vane pumps and piston pumps. By Cipian introduction, makes you a better understanding of the hydraulic pump. Sales pump (domestic), Jing Chong hydraulic (certified), the hydraulic pump by 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 to create a hydraulic leadership with the staff warmly welcome all inquiries negotiations to create the crystal to create a better future for the hydraulic.
