Libya hydraulic cylinder,shearing machine cylinder manufacturer,shearing machine cylinder(Libya shearing machine cylinder,produced by Hengyu Group)
shearing machine cylinder are widely used in Libya,because of simple structure and reliable operation,excellent temperature resistance,no transmission clearance.So our company has designed shearing machine cylinder for customers from Libya.
At the rated pressure, the thrust of the shearing machine cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the shearing machine cylinder is related to the diameter of the shearing machine cylinder, but not to the stroke of the shearing machine cylinder. Moreover, the larger the shearing machine cylinder diameter, the larger the area, and the greater the pressure obtained. To this point, we should have a correct understanding and clear understanding, so as to avoid problems in the use of the shearing machine cylinder.
shearing machine cylinder hydraulic oil selection: The recommended working oil viscosity of the shearing machine cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.
The difference between the plunger shearing machine cylinder and the piston shearing machine cylinder is that the piston in the shearing machine cylinder is replaced by a shaft plunger, which is used in hydraulic transmission requiring a long mechanical stroke, and can only input pressure oil from one direction, pressurize in a single direction, and form a thrust to push the plunger to move. The return trip of the plunger depends on the plunger itself to fall, and some rely on the spring to push back to the original position. Usually used plunger type shearing machine cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.
Because of the slightly complex structure of the buffer shearing machine cylinder, sometimes there will be problems, such as when the shearing machine cylinder with the buffer device is started in reverse, the piston often stops temporarily or reverses. Elimination method: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above fault phenomenon will occur when the buffer plunger leaves the end cover. In this regard, the orifice of the check valve should be increased.
What is the smallest cylinder size?
The smallest shape cylinder I have ever seen is a hydraulic clamping cylinder in the machine tool industry. Outer diameter 24 mm, total length 23 mm, travel 4 mm. Weighs 0.05 kg. Maximum clamping force 3500 Newtons.
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.
