The dismantling of the hydraulic oil cylinder

According to SONY to the working principle of hydraulic tools learned that each cylinder are almost similar, with a manual jacks, jack also is actually a simple cylinder. By manual pressurization stem (hydraulic manual pump) to make the hydraulic oil through a one-way valve into the cylinder, then into the cylinder of the hydraulic oil, because of the single valve can't back, forcing cylinder rod up, and then work continue to make the hydraulic oil into the hydraulic cylinder, thus constantly on the rise, will send when they open the hydraulic valve, the hydraulic oil tank back to, this is the most simple working principle, the other is based on the improved, cylinder and cylinder in the same principle.

Oil cylinder is mainly used in the need to support the weight of place for a long time, SONY for hydraulic tool called it can in the removal of oil pressure can still support the weight, and safe and reliable. Can be used in the underwater, single function, load retraction, nut self-locking make load more security, particularly in large engineering, control and self-locking jack is easy to operate, safe the holding device is designed, the built-in pressure relief valve to prevent overload, in order to protect the self-lock jack for safety operation.

SONY for hydraulic tool to understand guide rail hydraulic lift platform is a kind of shear fork type hydraulic lifting platform, for two or three layer between industrial workshop, restaurant, wine shop floor of cargo delivery, due to the minimum height is only 150-300 - mm, the most suitable for cannot industrial occasions of the excavation pit, without the upper lifting point at the same time, with a variety of forms (single column and double column, column 4), movements smooth, simple operation and reliable, hydraulic, electrical multiple protection, economic, easy for transmission between floors.

SJZ stationary lift loading and unloading platform is mainly used for the station, wharf, warehouse need to loading and unloading work sites, such as SONY for hydraulic tool to remind especially suitable for are not allowed to ground, set up long-term handling organs; And forklift trucks, hand push carrier such as loading and unloading machinery, will make your work efficiency greatly improved, the shear fork arm adopts box-type structure, safety coefficient is higher than the average value.

The advantages and disadvantages of oil cylinder

1, the pneumatic system USES pressure generally in the range of 0.2 to 1.0 Mpa, so the cylinder is not as powerful power components to make the oil cylinder

, hydraulic cylinder can do larger power component to use, or use the oil cylinder system.

2, tell from medium air can be unlimited, there is no cost and the difficulty of the supply side, will be used directly into the atmosphere, easy to handle, not pollution of hydraulic oil.

3, small air viscosity, resistance is less than the hydraulic oil.

SONY for hydraulic tool to understand the hydraulic oil cylinder disassembling matters needing attention

(1) remove the hydraulic oil cylinder before, should make hydraulic loop pressure relief. Otherwise, when the oil cylinder connected the tubing connector unscrewing, circuits of high pressure oil out quickly. Hydraulic circuit should be loosen when unloading overflow valve of the place such as a handwheel or pressure regulating screw, make the pressure oil unloading, then cut off the power or cut off power supply, make the hydraulic equipment to stop running.

(2) remove should prevent damage when the top of the piston rod thread, oil and the surface of the piston rod and the inner wall of the cylinder liner, etc. In order to prevent the piston rod and elongated bend or attachments, when placed application stow-wood bearing equilibrium.

(3) remove according to order. Due to all kinds of hydraulic cylinder structure and the size is not the same, disassembly sequence is also slightly different. General should put off the oil cylinder two cavity, and then remove the cylinder head, finally remove the piston and piston rod. When removing the cylinder head of hydraulic cylinder, the inside connection card key or card card key ring to use special tools, banning the use of a new; For flange end cover must be screwed out, do not allow the hammer or hard to pry. When piston and piston rod is difficult to take, not to play, should first find out the reason and then to remove.

(4) should try to create conditions to prevent discharge before and after unloading hydraulic cylinder parts are surrounding the pollution of dust and impurities. When, for example, remove, should as far as possible in a clean environment; After all the removed parts to use plastic cover, do not use cotton cloth or other work covered with a cloth.

(5) cylinder remove after carefully check, can continue to use to determine which parts, which parts can be repaired before use, the parts must be replaced.

(6) all parts must be carefully clean before assembly.

(7) to the correct installation of sealing device. (1) install the o-ring, don't pull it to the point of permanent deformation, and don't roll while suits, otherwise may leak due to form a distorted shape. When installing Y and v-shaped sealing ring (2), should pay attention to the direction of installation, avoid the oil instead. For the y-shaped sealing ring, the lips have to cope with the pressure oil cavity; In addition, Yx ring also note is use shaft or in the hole, don't wrong. V-shaped sealing ring by the different shapes of bearing ring, sealing ring and pressure ring, when pressure ring compression ring, ring sealing ring can be caused to form sealing function, when installation should be seal ring opening facing pressure oil cavity; Adjust pressure ring, is limited to not leak, not too tight, in case the seal resistance is too large. (3) sealing device, such as cooperate with sliding surface, the assembly should be coated with the right amount of hydraulic oil. (4) after removal of O ring and shield shall all be replaced.
