press hydraulic cylinder are widely used in Australia,because of clever hydraulic energy conversion,simple structure and reliable operation,excellent temperature resistance.So our company has designed press hydraulic cylinder for customers from Australia.

Introduction to press hydraulic cylinder:

In use, the press hydraulic cylinder should try to avoid the friction iron powder or iron filings formed by buffering the plunger. When the matching gap of the buffer device is small and the transverse load on the piston rod is large, the sintering phenomenon may be caused. These friction iron powder or the metal fragments that have fallen off as a result of sintering will remain in the press hydraulic cylinder.

The press hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or swinging motion). It is simple in structure and reliable in operation. When it is used to achieve reciprocating movement, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in various mechanical hydraulic systems. The output force of the press hydraulic cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; The press hydraulic cylinder is basically composed of press hydraulic cylinder and press hydraulic cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. Buffer device and exhaust device depending on the specific application, other devices are essential.

The coordination of the sliding parts of the press hydraulic cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.

When the press hydraulic cylinder is installed, the piston and the press hydraulic cylinder head and other parts have large mass, large size and large inertia, even if there is a lifting equipment auxiliary installation, because the specified clearance is small, no matter how hard it will be put into, therefore, the end of the piston or the press hydraulic cylinder head boss is easy to cause scars when it hits the inner surface of the press hydraulic cylinder wall. The solution to this problem: for a large number of small products, the use of autocratic assembly oriented tools during installation; For heavy, thick and large large and medium-sized press hydraulic cylinders, only careful and careful operation can be avoided.

Answers to some questions about press hydraulic cylinder:

Can one hydraulic pump with two cylinders work?
A hydraulic pump with two cylinders will work. Commonly used hydraulic pump types: 1, according to whether the flow can be adjusted can be divided into: variable pump and quantitative pump. The output flow can be adjusted according to the needs of the variable pump, the flow can not be adjusted called quantitative pump. 2, according to the pump structure commonly used in the hydraulic system is divided into: gear pump, vane pump and plunger pump 3 kinds. Gear pump: small volume, simple structure, the cleanliness of the oil requirements are not strict, the price is cheaper; However, the pump shaft is subjected to unbalanced force, serious wear and leakage. Vane pump: divided into double acting vane pump and single acting vane pump. The pump has uniform flow, smooth operation, low noise, higher pressure and volumetric efficiency than gear pump, and more complex structure than gear pump.

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.
