Abstract
The invention relates to a hydraulic cylinder. The hydraulic cylinder comprises a cylinder barrel. A cylinder cover is arranged on one side of the cylinder barrel. A plurality of locking screws are arranged between the cylinder barrel and the cylinder cover. A liquid inlet hole is formed in the center position of the cylinder cover, and a sealing cover is arranged on the other side of the cylinder barrel and connected with an end cover. A piston rod is arranged in the cylinder barrel, one end of the piston rod is connected with a piston, and a sealing layer is arranged between the end cover and the piston rod. A sealing pad is arranged between the sealing cover and the cylinder barrel. Two sealing rings are arranged between the piston and the cylinder barrel. An anti-corrosion layer is arranged on the end face of the piston. A locking spring and a locking nut are arranged between the piston and the piston rod. During using, the hydraulic cylinder has good sealing performance under the action of the sealing layer, the sealing pad and the sealing rings, and the service life of the hydraulic cylinder is effectively prolonged; and corrosion of the piston can be avoided through the anti-corrosion layer, and stable installing of the piston can be achieved through the locking spring.

Technical field
The present invention relates to industrial technical field, particularly relate to a kind of hydraulic cylinder.
Background technology
The hydraulic pressure that hydraulic energy is changed into mechanical energy by hydraulic cylinder, do straight reciprocating motion (or oscillating motion) performs unit
Part.Its simple in construction, reliable operation.When realizing moving back and forth with it, deceleration device can be removed from, and there is no drive gap,
Stable movement, is therefore used widely in the hydraulic system of various machineries.Hydraulic cylinder power output and piston effective area and
The pressure reduction on its both sides is directly proportional；Hydraulic cylinder substantially by cylinder barrel and cylinder cap, piston and piston rod, sealing device, buffer unit with
Exhaust apparatus forms.Buffer unit and exhaust apparatus are depending on concrete application scenario, and other devices are the most essential.
According to the version of conventional hydraulic cylinder, three types can be classified as: the structure of the hydraulic cylinder of environmental sanitation refuse vehicle
Form is varied, and its sorting technique also has multiple: can be divided into straight reciprocating motion formula and gyroscopic pendulum dynamic formula by motion mode；Press
Single-acting formula, double-acting type can be divided into by action of hydraulic force situation；Piston type, plunger type can be divided into by version, multistage stretched
Contract telescopic, pinion and-rack etc.；Pull bar, earrings, footing, hinge etc. can be divided into by installation form；Can be divided into by pressure rating
16Mpa, 25Mpa, 31.5Mpa etc..
Existing hydraulic cylinder structure is complicated, and sealing is poor, is susceptible to leakage, affects hydraulic cylinder after using a period of time
Service life.
Summary of the invention
