flying wing compartment hydraulic cylinder are widely used in Chile，because of long service life，smooth movement，high work efficiency.So our company has designed flying wing compartment hydraulic cylinder for customers from Chile.

Introduction to flying wing compartment hydraulic cylinder:

The assembly work of the flying wing compartment hydraulic cylinder has a great impact on the quality of the flying wing compartment hydraulic cylinder: each part must be carefully cleaned before assembly; To correctly install the sealing device everywhere: when installing the sealing ring, pay attention to its installation direction to avoid oil leakage due to installation, and its lip should be equipped with a pressure oil chamber. In addition, because it is a YX-shaped sealing ring, it is necessary to pay attention to distinguish between shaft and hole use, do not install wrong; Because the sealing device is matched with the sliding surface, an appropriate amount of hydraulic oil should be applied during assembly; The special wrench should be used when the threaded coupling is tightened, and the torque should meet the standard requirements; After the piston and piston rod are assembled, it is necessary to measure whether the coaxiality and straightness on the full length are out of whack. After assembly, there should be no blocking sensation and uneven resistance when the piston assembly moves.

When the hydraulic oil is not pumped into the flying wing compartment hydraulic cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the flying wing compartment hydraulic cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.

Piston flying wing compartment hydraulic cylinder is widely used in hydraulic transmission. When the flying wing compartment hydraulic cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the flying wing compartment hydraulic cylinder, and uses the pressure difference of hydraulic oil on both sides of the piston to realize the reciprocating movement of the piston. If you want to speed up the forward speed of the piston, the return oil in the flying wing compartment hydraulic cylinder can be controlled by the valve and directly input into the inlet pipe to participate in the work of the piston to achieve rapid movement of the piston, but the thrust of the piston is reduced much.

flying wing compartment hydraulic cylinder is the most important part of construction machinery, the traditional processing method is: broaching flying wing compartment hydraulic cylinder block - fine boring flying wing compartment hydraulic cylinder block - grinding flying wing compartment hydraulic cylinder block. The rolling method is: broaching flying wing compartment hydraulic cylinder block - fine boring flying wing compartment hydraulic cylinder block - rolling flying wing compartment hydraulic cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the flying wing compartment hydraulic cylinder block is about 1-2 days, rolling 1 meter of the flying wing compartment hydraulic cylinder block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3 μm before rolling to Ra0.4 ~ 0.8μm, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the flying wing compartment hydraulic cylinder increases by 25%. If the flying wing compartment hydraulic cylinder life is only considered, it is increased by 2 to 3 times, and the boring and rolling process is 3 times more efficient than the grinding process In particular, if you want to make high-quality flying wing compartment hydraulic cylinders, you must take the rolling production process. After the flying wing compartment hydraulic cylinder is rolled, there is no sharp tiny edge on the surface, and long-term motion friction will not damage the seal ring or seal, which is particularly important in the hydraulic industry.

Answers to some questions about flying wing compartment hydraulic cylinder:

How to design the guide sleeve of cylinder diameter 400?
The purpose of the guide sleeve is to guide and seal. Therefore, it is necessary to look at the speed of the piston rod, working pressure and radial force. High speed, medium pressure, no (or very little) radial force, with a Steseal. Low speed and heavy load, medium radial force, combined seal. High speed and heavy load, large radial force, sealed with DU sleeve + copper ring + combination. The combination seal must have a lubricating oil passage, and a seal must be added to the outside of the oil passage.

Why is the hydraulic cylinder of the larger excavator arm upside down?
The weight of the excavating arm of a large excavator will be very heavy, and an oil cylinder has two cavities, one is a rod cavity, and the other is a rodless cavity. The lifting force of the excavator is the product of the ortho-projection area of the piston rod cavity by the oil pressure, so the strength of the rodless cavity is much greater than that of the rod cavity. And the parallel bars with the piston rod facing down are also conducive to assembly and future maintenance. So a large excavator has to keep the cylinder facing down.
