Sri Lanka 400 tons hydrauli ccylinder

(Sri Lanka 400 tons hydrauli ccylinder,produced by Hengyu Hydraulic Cylinder Factory)

400 tons hydrauli ccylinder are widely used in Sri Lanka,because of high work efficiency,excellent fatigue and impact resistance,simple structure and reliable operation.So our company has designed 400 tons hydrauli ccylinder for customers from Sri Lanka.

Introduction to 400 tons hydrauli ccylinder:

If the seal of the 400 tons hydrauli ccylinder is abnormal wear, you can check whether the speed control valve is improperly adjusted, resulting in too high back pressure and improper installation of the seal or hydraulic oil contamination. The second is whether there is a foreign body entering the assembly and the quality of the sealing material is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and 400 tons hydrauli ccylinder, and the phenomenon of "pulling the 400 tons hydrauli ccylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operation and improvement should be done according to the installation instructions.

The difference between the plunger 400 tons hydrauli ccylinder and the piston 400 tons hydrauli ccylinder is that the piston in the 400 tons hydrauli ccylinder is replaced by a shaft plunger, which is used in hydraulic transmission requiring a long mechanical stroke, and can only input pressure oil from one direction, pressurize in a single direction, and form a thrust to push the plunger to move. The return trip of the plunger depends on the plunger itself to fall, and some rely on the spring to push back to the original position. Usually used plunger type 400 tons hydrauli ccylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.

The body of the 400 tons hydrauli ccylinder on the processing process requirements: the body of the 400 tons hydrauli ccylinder is an important and essential part of the 400 tons hydrauli ccylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the 400 tons hydrauli ccylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.

How to repair the 400 tons hydrauli ccylinder body when it is damaged: When the 400 tons hydrauli ccylinder has trace deformation and shallow tensile marks, the 400 tons hydrauli ccylinder is repaired by strong honing process. The heavy honing process can repair 400 tons hydrauli ccylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the 400 tons hydrauli ccylinder can meet the technical requirements.

Answers to some questions about 400 tons hydrauli ccylinder:

Are hydraulic cylinders divided into oil cylinders and water cylinders? What's the difference between the two types?
There are oil cylinders and water cylinders. The two cylinders are used in different environments. Oil cylinders are generally used in places where there is less demand for media, which is our most common hydraulic cylinders. Water cylinders are mainly used for large tonnage presses. Because the equipment is too large, the use of hydraulic oil will cause a relatively large waste. However, water is not pure water, there are oil-in-water emulsion and water-in-oil emulsion. Water has another benefit: it's flame retardant. It is especially suitable for some flammable and explosive occasions. Or with water glycol. The use of pure water is very little, mainly because the seal is not good and easy to rust.

When the cylinder is tested, why can't the pressure be maintained with the balance valve?
Because the oil into the oil chamber through the hydraulic lock on the control oil circuit through the other side of the spool, the original valve is designed in this way. It locks the circuit after the oil supply circuit loses pressure, on the contrary, if you keep supplying pressure, it is always in the state of opening the other side of the one-way spool. So this valve can't be used in the test.
