Background technology
Engineering hydraulic cylinder be hydraulic energy is changed into mechanical energy, the hydraulic pressure that does straight reciprocating motion (or oscillating motion) is held
Units.Its structure is simple, reliable operation.When being realized with it moving back and forth, deceleration device can be removed from, and not have between transmission
Gap, stable movement, therefore it is used widely in the hydraulic system of various machineries.Engineering hydraulic cylinder power output and piston are effective
The pressure reduction on area and its both sides is directly proportional；Engineering hydraulic cylinder substantially by cylinder barrel and cylinder cap, piston and piston rod, sealing device,
Buffer unit is formed with exhaust apparatus., depending on concrete application occasion, other devices then must for buffer unit and exhaust apparatus
Few.
According to the version of conventional engineering hydraulic cylinder, three types can be classified as：The engineering hydraulic pressure of environmental sanitation refuse vehicle
The version of cylinder is varied, and its sorting technique also has multiple：Straight reciprocating motion formula and revolution can be divided into by motion mode
Swing type；Single-acting formula, double-acting type can be divided into by by action of hydraulic force situation；Piston type, plunger can be divided into by version
Formula, multi-stage expansion are telescopic, pinion and-rack etc.；Pull bar, earrings, footing, hinge etc. can be divided into by installation form；Pressing force etc.
Level can be divided into 16Mpa, 25Mpa, 31.5Mpa etc..
Existing engineering hydraulic cylinder structure is complicated, and sealing is poor, using being susceptible to after a period of time leak, affects engineering
The service life of hydraulic cylinder.
