(Czech Republic roller press hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）

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

Introduction to roller press hydraulic cylinder:

In use, the roller press 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 roller press hydraulic cylinder.

If it is found that the roller press hydraulic cylinder lubrication is poor or the roller press hydraulic cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the roller press hydraulic cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the roller press hydraulic cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the roller press hydraulic cylinder center line. In this way, when the piston works in the roller press hydraulic cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the roller press hydraulic cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

roller press hydraulic cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the roller press hydraulic cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the roller press hydraulic cylinder. c. The roller press hydraulic cylinder seal is extruded, if the O-ring is obviously extruded at the roller press hydraulic cylinder seal, replace the roller press hydraulic cylinder seal.

The body of the roller press hydraulic cylinder on the processing process requirements: the body of the roller press hydraulic cylinder is an important and essential part of the roller press hydraulic cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the roller press hydraulic cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.

Answers to some questions about roller press hydraulic cylinder:

What hydraulic oil does servo cylinder generally use?
The medium used by the cylinder generally depends on the working condition of the use, including pressure, installation environment, sealing material, etc. I think the first thing to consider is the impact of the sealing material. Mineral oil is a good choice if it is not too fire-resistant or used in a high temperature environment. 1, servo cylinder features: closed-loop servo control, control accuracy of 0.01mm; Precise control of thrust, increase pressure sensor, control accuracy up to 1%; It is easy to connect with PLC and other control systems to achieve high precision motion control. Low noise, energy saving, clean, high rigidity, impact resistance, long life, simple operation and maintenance. 2, the servo cylinder can be fault-free in harsh environments, and the protection level can reach IP66.

How does the hydraulic solenoid valve realize that the cylinder stops at any position?
Use an O-type medium function solenoid directional valve, or use a Y-type solenoid directional valve and a hydraulically controlled check valve.
