Foreign matter generated in operation a. Because the cushion plunger not formed by the friction strength of iron or iron filings. Buffer means with the gap is very small thin cylinder, the piston rod suffered lateral load is large, it may cause sintering phenomenon. The friction has been falling off the iron or metal fragments generated due to sintering will remain in the cylinder. b. scars inside the cylinder wall surface. Master piston sliding surface pressure acting hydraulic cylinder, causing sintering phenomena occur so crowded cylinder surface crack, crack of metal pushed off, stay in the cylinder can cause a variety of injuries hydraulic drive cylinder and motor cylinder, they are It is the fluid pressure energy into mechanical energy and means of its output. Cylinder main output linear motion and force. Hydraulic cylinders take many forms, according to different characteristics of their institutions which can be divided into piston, piston and swing three categories, according to the mode of action he can be divided into single and double acting. Piston cylinder, piston-cylinder is mainly used for: mechanical jacks hydraulic cylinders, such as excavators; research, such as the structure of university laboratories. Piston-cylinder used for pressure testing machine, such as Jinan Test, think of testing machines for materials testing ultra-high pressure cylinders, Lu Hydraulic (online consultation), provided by the Texas Lu Hebei cylinders hydraulic equipment factory. Texas Lu force hydraulic machinery plant (www.luliyeya.com) is an industry leader in Shandong Dezhou, hydraulic machinery and parts, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Lu Hydraulic leadership with the staff warmly welcome all inquiries negotiations to create Lu Hydraulic better future.
