Sweden yg series hydraulic cylinder

(Sweden yg series hydraulic cylinder,produced by Hengyu Group)

yg series hydraulic cylinder are widely used in Sweden,because of no need for deceleration device,high work efficiency,excellent fatigue and impact resistance.So our company has designed yg series hydraulic cylinder for customers from Sweden.

Introduction to yg series hydraulic cylinder:

If the seal of the yg series hydraulic cylinder 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 yg series hydraulic cylinder, and the phenomenon of "pulling the yg series hydraulic cylinder" 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.

yg series hydraulic cylinder is the most important part of construction machinery, the traditional processing method is: broaching yg series hydraulic cylinder block - fine boring yg series hydraulic cylinder block - grinding yg series hydraulic cylinder block. The rolling method is: broaching yg series hydraulic cylinder block - fine boring yg series hydraulic cylinder block - rolling yg series hydraulic cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the yg series hydraulic cylinder block is about 1-2 days, rolling 1 meter of the yg series 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 yg series hydraulic cylinder increases by 25%. If the yg series 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 yg series hydraulic cylinders, you must take the rolling production process. After the yg series 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 it is found that the yg series hydraulic cylinder lubrication is poor or the yg series hydraulic cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the yg series hydraulic cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the yg series hydraulic cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the yg series hydraulic cylinder center line. In this way, when the piston works in the yg series hydraulic cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the yg series hydraulic cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

1, the hydraulic machinery should be kept clean, in order to prevent dust and debris from falling into the oil, the tank should be sealed. 2, the oil in the tank should be replaced regularly according to the working condition. When changing the oil, the dirt and impurities accumulated at the bottom of the tank should be removed and the tank should be cleaned. 3, hydraulic oil, oil drums should be set in a clean and safe place to strengthen management. The oil drum, oil filter, oil funnel, oil pipe, etc. used should be kept clean. The oil drums for loading hydraulic oil must be cleaned in advance, and the oil drums should be dedicated and not mixed with other oil drums.

Answers to some questions about yg series hydraulic cylinder:

How to distinguish large cavity and small cavity of excavator rod cylinder ?
Single rod piston cylinder is a form of cylinder that is used relatively most, and the boom, bucket, dozer shovel cylinder are all in this form. Among them, the rodless cavity is also called the large cavity, and the rodless cavity is also called the small cavity. Therefore, the cylinder cavity on the side with the exposed piston rod is the small cavity, and the cylinder cavity on the side without the exposed rod is the large cavity.

What is a mold core cylinder?
Simple plastic parts can be directly pushed out by the ejector rod after injection molding, complex plastic parts can not be directly pushed out by the ejector rod after injection molding, to make the interference part active, control its position through the cylinder (injection molding into the mold, so that the shape of the plastic parts meet the demand, exit after opening the mold, so that the plastic parts are smoothly pushed out), This kind of cylinder is the mold core cylinder.
