(Congo shearing machine cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to shearing machine cylinder:

The internal leakage of the shearing machine cylinder should be prevented when the shearing machine cylinder is used. The internal leakage of shearing machine cylinder includes the leakage caused by excessive wear of shearing machine cylinder block seal, piston rod and seal cover seal and piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time.

shearing machine cylinder piston rod material selection and technical requirements: (I), because there is no special requirements, so use 45 steel as the piston rod material, the design of the piston rod only withstand pressure stress, so no modulation processing; (ii) The coaxial tolerance of the shaft journal and the outer circle of the mounting piston is not greater than 0.01mm, so as to ensure the coaxial degree of the outer circle of the piston rod and the outer circle of the piston, and avoid the stuck phenomenon of the piston and the shearing machine cylinder, the piston rod and the guide. The vertical tolerance between the end face of the mounting piston and the axis of the piston rod is not more than 0.04mm/100mm to ensure that the piston installation does not produce skew; (iii) The outer circle of the piston rod should pay attention to the roughness; (iv) Because it is operated under low load conditions, surface treatment is omitted.

The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the shearing machine cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.

shearing machine 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 shearing machine cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the shearing machine cylinder. c. The shearing machine cylinder seal is extruded, if the O-ring is obviously extruded at the shearing machine cylinder seal, replace the shearing machine cylinder seal.

Answers to some questions about shearing machine cylinder:

What is a mold core cylinder?
Simple plastic parts can be directly pushed out by the ejector rod after injection molding, complex plastic parts can not be directly pushed out by the ejector rod after injection molding, to make the interference part active, control its position through the cylinder (injection molding into the mold, so that the shape of the plastic parts meet the demand, exit after opening the mold, so that the plastic parts are smoothly pushed out), This kind of cylinder is the mold core cylinder.

Is a hydraulic cylinder and a jack the same thing?
Strictly speaking, no. Although the hydraulic principle is used, and even some of the longer jacks are similar to the cylinder, the internal structure of the two is different. There is a check valve inside the jack. After the top lift, the check valve locks the hydraulic oil circuit, and the hydraulic oil only enters and does not exit after the check valve locks, and can be lowered to complete a reciprocating movement. The cylinder is usually connected to the distribution tube to control the movement, and works with a wide variety of distribution valves and distribution systems according to different needs. The jack only needs a simple check valve.
