(Italy accumulator hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

accumulator hydraulic cylinder are widely used in Italy，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed accumulator hydraulic cylinder for customers from Italy.

Introduction to accumulator hydraulic cylinder:

The accumulator hydraulic cylinder should be vented: when the accumulator hydraulic cylinder is installed or parked for a long time to work again, the air will penetrate into the accumulator hydraulic cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the accumulator hydraulic cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the accumulator hydraulic cylinder, the oil is best entered and discharged from the highest point of the accumulator hydraulic cylinder. accumulator hydraulic cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

In use, the accumulator 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 accumulator hydraulic cylinder.

accumulator hydraulic cylinder is the most important part of construction machinery, the traditional processing method is: broaching accumulator hydraulic cylinder block - fine boring accumulator hydraulic cylinder block - grinding accumulator hydraulic cylinder block. The rolling method is: broaching accumulator hydraulic cylinder block - fine boring accumulator hydraulic cylinder block - rolling accumulator hydraulic cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the accumulator hydraulic cylinder block is about 1-2 days, rolling 1 meter of the accumulator 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 accumulator hydraulic cylinder increases by 25%. If the accumulator 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 accumulator hydraulic cylinders, you must take the rolling production process. After the accumulator 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.

If air enters the hydraulic system, the accumulator hydraulic cylinder will not operate normally, mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced.

Answers to some questions about accumulator hydraulic cylinder:

How does the cylinder of the shearing machine work?
Plate shear is a machine that cuts a sheet with a reciprocating straight motion from one blade to another. Through the moving upper blade and the fixed lower blade, the shear force is applied to the metal sheet of various thicknesses with a reasonable blade gap, so that the sheet is broken and separated according to the required size. Shearing machine belongs to one of the forging machinery, the main role is the metal processing industry. Products are widely used in aviation, light industry, metallurgy, chemical industry, construction, shipbuilding, automobile, electric power, electrical appliances, decoration and other industries to provide the required special machinery and complete sets of equipment. Working principle: The hydraulic system is used to drive the hydraulic cylinder to output a strong shear force to complete the shearing work.

How do hydraulic equipment and hydraulic cylinders maintain a certain pressure after pressing to a certain position?
There are several methods. 1. You can use a constant pressure variable pump to adjust the control pressure of the pump to the pressure required by the cylinder, so that when the cylinder is in place, the pump uses the minimum flow rate to maintain the pressure, and the system is more energy saving. 2. If the pressure is maintained for a short time, a hydraulic control check valve can be added to the oil inlet end of the cylinder to close the cylinder and maintain the pressure. If the volume of the cylinder is large, an accumulator can be added between the valve and the cylinder to maintain pressure for 10-30 minutes. 3. You can add a small flow pump, the large pump after unloading, the small pump has been running, specifically for maintaining pressure.
