(Bulgaria servo cylinder,produced by Hengyu Group）

servo cylinder are widely used in Bulgaria，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed servo cylinder for customers from Bulgaria.

Introduction to servo cylinder:

There are some honeycomb holes in the inner wall of the servo cylinder, piston or piston rod surface. How is this formed? When we repair the servo cylinder, we can see that there are some honeycomb holes on the inner wall of the servo cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the servo cylinder is targeted to prevent. Is very necessary.

The method of sleeve servo cylinder to improve the processing quality: there is a big gap in the service life of post-plating polishing and post-plating polishing, especially in mass production. Strictly clean the flying edge and burr of mechanical components, especially the edge of the sealing groove, and the tiny metal burr, strictly clean before assembly. The surface fatigue strength and stress corrosion resistance of the servo cylinder can be significantly improved by rolling in the finishing of the inner holes of the servo cylinder. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.

servo cylinder spool stuck or valve hole blocked How to solve: When the flow valve or direction valve spool stuck or valve hole blocked, the servo cylinder prone to misoperation or action failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium.

When the long-stroke servo cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in servo cylinder head seal damage, oil leakage, and piston sleep in the servo cylinder. The following measures can be taken: increase the piston plan to adjust the piston outer circle and process it into a convex drum, so that the piston can self-position, improve the force situation, and reduce and avoid pulling the servo cylinder; The piston and the piston rod are connected with a spherical joint.

Answers to some questions about servo cylinder:

How does the cylinder work?
Hydraulic transmission principle: oil as the working medium, through the change of the sealing volume to transfer movement, through the internal pressure of the oil to transfer power. 1. The power part - converts the mechanical energy of the prime mover into the pressure energy of the oil (hydraulic energy). For example: hydraulic pump. 2, the executive part - the hydraulic pump input oil pressure energy into the mechanical energy to drive the working mechanism. For example: hydraulic cylinder, hydraulic motor. 3, the control part - used to control and adjust the oil pressure, flow and flow direction. For example: pressure control valve, flow control valve and direction control valve. 4, the auxiliary part - the first three parts are connected together to form a system, which plays the role of oil storage, filtration, measurement and sealing.

When the hydraulic cylinder changes from fast to slow, how can the slow speed become more even and the speed can be adjusted?
Reversing valve set 2 reversing valves. The back of one valve goes directly to the cylinder, running at full speed for fast action. Add a speed control valve behind the other valve, and then connect to the cylinder to achieve slow action, you can adjust the opening of the speed control valve, to achieve the speed of the cylinder can be adjusted. An import speed control valve to more than 1,000 yuan, if you think it is too expensive, you can also use the throttle valve instead. However, the throttle valve is greatly affected by the load change.
