flanged hydraulic cylinder are widely used in Holland，because of no need for deceleration device，long service life，smooth movement.So our company has designed flanged hydraulic cylinder for customers from Holland.

Introduction to flanged hydraulic cylinder:

The flanged hydraulic cylinder should be vented: when the flanged hydraulic cylinder is installed or parked for a long time to work again, the air will penetrate into the flanged 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 flanged hydraulic cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the flanged hydraulic cylinder, the oil is best entered and discharged from the highest point of the flanged hydraulic cylinder. flanged 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.

When installing the flanged hydraulic cylinder pipe, the pipe should be cleaned after installation, and should not pass through the flanged hydraulic cylinder block, and the by-pass pipe must be installed in front of the oil port of the flanged hydraulic cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the flanged hydraulic cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the flanged hydraulic cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.

flanged hydraulic cylinder piston sealing is best to use Yx ring, polyurethane and polytetrafluoroethylene sealing material combination, can significantly improve the sealing performance: (I), reduce friction resistance, no crawling phenomenon; (ii) Have good dynamic and static sealing, wear resistance, long service life; (iii) The installation groove is simple, and the disassembly is simple.

The internal leakage of the flanged hydraulic cylinder is an important indicator to measure the quality of the flanged hydraulic cylinder: the internal leakage of the flanged hydraulic cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the flanged hydraulic cylinder, so that the flanged hydraulic cylinder can not accurately and stably stop in a certain position of the flanged hydraulic cylinder, so it is one of the main indicators of the flanged hydraulic cylinder.

Answers to some questions about flanged hydraulic cylinder:

How to refuel pneumatic riveting cylinder?
First put the gun flat, that is, horizontally, while pushing the stroke positioning pin and loosen the back cover, rotate to the left for a maximum of five turns, and then use a wrench to loosen the oil sealing screw, slowly add the hydraulic oil and let the air out, fill up to tighten the oil sealing screw. This process of adding hydraulic oil is over.

What welding rod is used for hydraulic cylinder welding?
There are several reasons for bad welding of hydraulic cylinder: 1. There is hydraulic oil on the welding surface, wipe it with a rag, there will be bubbles in the welding process, and it will not last for a few days. You have to remove it, drain it, wash it off with gasoline and try again. 2. Open the groove before welding, it is not deep enough to use the Angle grinding machine, and can not find the accurate crack position. 3. The material of the cylinder itself is not clear, the welding performance of more than 35 steel is not good, in the factory welding needs to preheat, the welding rod should also be dried and insulated, there is no such condition on the site.
