Bolivia hinge shaft cylinder

(Bolivia hinge shaft cylinder,produced by Hengyu Hydraulic Co., Ltd)

hinge shaft cylinder are widely used in Bolivia,because of no transmission clearance,simple structure and reliable operation,excellent temperature resistance.So our company has designed hinge shaft cylinder for customers from Bolivia.

Introduction to hinge shaft cylinder:

The commonly used buffer structure of the hinge shaft cylinder is composed of a piston boss and a hinge shaft cylinder head groove. When the piston moves close to the hinge shaft cylinder head, it gradually enters the groove, and the oil in the groove is extruded through the gap between the boss and the groove, which increases the oil return resistance, produces the braking effect and realizes the buffer. Generally, a buffer mechanism should be used when the pressure is above 10MP.

The method of sleeve hinge shaft 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 hinge shaft cylinder can be significantly improved by rolling in the finishing of the inner holes of the hinge shaft cylinder. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.

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

The piston seal of the hinge shaft cylinder is the main element to prevent leakage in the hinge shaft cylinder. For the lip seal, it should focus on checking whether the lip edge is bruised and worn, and for the combination seal, it should focus on checking the wear of the sealing surface, and then determine whether the seal can be used. In addition, it is necessary to check whether the static seal between the piston and the piston rod is crushed. The piston rod seal should focus on checking the wear of the seals and supporting rings.

Answers to some questions about hinge shaft cylinder:

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.

To achieve the same stroke, which is better, hydraulic cylinder or lead screw?
If there is batch action, then the hydraulic pressure is better. Hydraulic: smooth operation, no lubrication, easy control, high control accuracy (can use proportional or servo system), the key is to manually control, but certainly to support the hydraulic system, for a single action must cost. Maintenance costs are also high. Lead screw: simple structure, easy to achieve, convenient maintenance, but must be lubricated, can not be manual, or manual control is inconvenient. See where it is used, if it is used in high-precision occasions, it must only be hydraulic, because the lead screw has a gap. There are many hydraulic actions, the hydraulic system itself must be prepared, then the use of hydraulic pressure is also very economical.
