(Austria roller press hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）
roller press hydraulic cylinder are widely used in Austria，because of long service life，smooth movement，high work efficiency.So our company has designed roller press hydraulic cylinder for customers from Austria.
Under normal circumstances, the roller press hydraulic cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the roller press hydraulic cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the roller press hydraulic cylinder and the end cover, the piston and the piston rod, the piston and the roller press hydraulic cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the roller press hydraulic cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.
The scar on the sliding surface of the roller press hydraulic cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the roller press hydraulic cylinder wall. Therefore, before installation, these scars must be fully repaired.
The roller press hydraulic cylinder should be used correctly and maintained regularly. The roller press hydraulic cylinder should be deflated before use, the buffer regulating valve should be adjusted to a reasonable position, the cleanliness of the oil should be checked regularly, the dust on the roller press hydraulic cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.
roller press hydraulic cylinder and hydraulic station selection: Select the type and structure of the roller press hydraulic cylinder according to the operation requirements of the main engine. According to the external load force borne by the roller press hydraulic cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the roller press hydraulic cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the roller press hydraulic cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the roller press hydraulic cylinder, the diameter of the piston and the piston rod.
Design a hydraulic cylinder, the inner diameter of the cylinder is 100mm, what size of piston rod is best used?
This involves how much speed ratio you need, that is, the area ratio of the rod cavity and the rodless cavity, if the weight is relatively large, it is recommended that the speed ratio choose 2, that is, the piston rod diameter choose 70mm, under normal circumstances, the speed ratio choose 1.46, the piston rod diameter choose 55mm. Of course, there are many factors that affect the diameter of the piston rod, such as stroke, stroke is too long, in order to stabilize the work of the hydraulic cylinder, its diameter also needs to choose a relatively large, sometimes even non-standard products, need to choose according to the actual situation.
What is the main maintenance of the cylinder?
After disassembling the cylinder: 1, clean the cylinder and piston; 2, replace all seals; 3, if there is a valve to repair, to ensure sealing and flexible; 4, deal with all deformation parts; 5. Installation experiment.
