Pakistan hydraulic cylinder,servo hydraulic cylinder manufacturer,servo hydraulic cylinder
(Pakistan servo hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）
servo hydraulic cylinder are widely used in Pakistan，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed servo hydraulic cylinder for customers from Pakistan.
The wear of the hard chromium plating layer of the servo hydraulic cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.
servo hydraulic cylinder hydraulic oil selection: The recommended working oil viscosity of the servo hydraulic cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.
The piston seal of the servo hydraulic cylinder is the main element to prevent leakage in the servo hydraulic cylinder. For the lip seal, it should focus on checking whether the lip edge is bruised and worn, and for the combination seal, it should focus on checking the wear of the sealing surface, and then determine whether the seal can be used. In addition, it is necessary to check whether the static seal between the piston and the piston rod is crushed. The piston rod seal should focus on checking the wear of the seals and supporting rings.
Under normal circumstances, the servo 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 servo hydraulic cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the servo hydraulic cylinder and the end cover, the piston and the piston rod, the piston and the servo 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 servo hydraulic cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.
What is a variable amplitude cylinder?
The type of variable amplitude cylinder is: double acting piston type cylinder, single acting plunger type cylinder, double acting two-stage telescopic cylinder. Double acting piston cylinder is the most common application. The oil cylinder has two oil outlets, and when the oil is fed into the A port, the oil is returned to the B port; If the oil inlet of the B port is returned to the oil of the A port, the reciprocating movement of the piston depends on the effect of pressure. Single-acting plunger (or piston) cylinder has only one oil port, the pressure oil can only supply oil to one side of the plunger in the cylinder, the plunger moves in one direction under the action of pressure oil, and the return stroke of the plunger is driven by the gravity of the lifting arm, such as the LT1040 truck crane variable amplitude cylinder. The double-acting two-stage telescopic cylinder is a set structure, and the two-stage piston rod is like a tie rod antenna set in the cylinder barrel.
What type of seal is the cylinder of shaft 50?
You won't know the exact model until you take it apart. Oil seals have O, Y, Yx, KYx, U, UN, UHS, YA, St, Gray, Yamagata, Lei type, etc. It is difficult to know what kind of oil seal the designer chooses. Cylinder oil seal installation method: 1. Receive a fixed number of oil seals. 2. From receiving the oil seal to assembly, it must be kept clean. 3. Before assembly, check the oil seal and measure whether the size of each part of the oil seal is consistent with the size of the shaft and cavity. Before the oil seal is installed, the size of the shaft diameter should be clearly compared with the inner diameter of the oil seal. The inner cavity size should be suitable for the outer diameter width of the oil seal. Check the lip of the oil seal for damage.
