Vietnam roller press hydraulic cylinder

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

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

Introduction to roller press hydraulic cylinder:

roller press hydraulic cylinder buffer valve inspection and maintenance: For the valve buffer roller press hydraulic cylinder, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.

roller press hydraulic cylinder piston rod material selection and requirements: ① piston rod is usually made of 45 steel. When there is a large impact force and heavy load transmission, it is made of 40Cr steel. This is to ensure that the piston rod has sufficient working strength. The piston rod is generally designed as a roller press hydraulic cylinder, if the diameter is larger, the hollow piston rod can be used. Made of No. 45 seamless steel pipe. ③ When the piston rod is manufactured, the blank should be first forged and conditioned after mechanical rough processing, and the hardness of HB=230 ~ 250. The purpose of conditioning is to improve the machining performance and increase the working strength of the material. ④ The surface roughness Ra of the piston rod after finishing should not be greater than 0.65μm. ⑤ In order to improve the corrosion resistance of the piston rod, the working surface of the rod can be plated with hard chromium. ⑥ The piston rod and the end cap are guided by H8 ' roller press hydraulic cylinder piston rod industry standard: piston rod diameter series of national recommended standard GB/T2348-1993. Piston rod thread size series standard GB/T2350-1980. Please refer to execute. There is no industry standard for piston rods Both the roller press hydraulic cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The roller press hydraulic cylinder mainly outputs linear motion and force. The roller press hydraulic cylinder has a variety of forms, according to the different characteristics of its mechanism it can be divided into piston type, plunger type and swing type three categories, according to the mode of action he can be divided into single action and double action. Piston roller press hydraulic cylinder, plunger roller press hydraulic cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger roller press hydraulic cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.

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.

When the roller press hydraulic cylinder wear is serious, you can try to use an alloy scraper to shave grooves with a depth of more than 1mm on the surface of the slip injury, then clean the grooves with acetone, apply the adjusted TS311 anti-wear repair agent on the polished surface with the roller press hydraulic cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the roller press hydraulic cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the roller press hydraulic cylinder can meet the requirements by grinding. However, the life and reliability of this repair roller press hydraulic cylinder are not high.

Answers to some questions about roller press hydraulic cylinder:

The inner diameter of the injection cylinder is 203.2mm and the diameter of the screw is 63.5mm. What is the enhancement ratio?
Oil pressure multiplied by the cross-sectional area of the cylinder is equal to the theoretical output force value, and then multiplied by the efficiency of the cylinder is equal to the actual output force value, and the oil pressure can be calculated by inverting the value input.

What diameter cylinder is needed for a force of 5 tons?
It depends on the pressure of your system pump. If the normal working pressure of the system is about 8MPa, then the diameter of the cylinder should be 100 mm.
