(America shearing machine cylinder,produced by Hengyu Hydraulic Cylinder Factory）

shearing machine cylinder are widely used in America，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed shearing machine cylinder for customers from America.

Introduction to shearing machine cylinder:

The internal leakage of the shearing machine cylinder is an important indicator to measure the quality of the shearing machine cylinder: the internal leakage of the shearing machine cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the shearing machine cylinder, so that the shearing machine cylinder can not accurately and stably stop in a certain position of the shearing machine cylinder, so it is one of the main indicators of the shearing machine cylinder.

Do not regularly check the damage of the chrome layer of the shearing machine cylinder: completely extend the shearing machine cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the shearing machine cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the shearing machine cylinder seal. Welding slag is strictly prohibited on the surface of the shearing machine cylinder.

When the shearing machine 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 shearing machine cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the shearing machine cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the shearing machine cylinder can meet the requirements by grinding. However, the life and reliability of this repair shearing machine cylinder are not high.

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

Answers to some questions about shearing machine cylinder:

What components can control cylinder rising and falling speed and the speed is adjustable?
A throttle or special solenoid valve is required. The reversing valve can choose the three-position reversing valve with P-type middle function. When rising, the reversing valve can be changed to the middle position to achieve differential connection and the fastest speed. Add a combination valve one-way throttle valve in the oil return circuit, connection mode: when the cylinder rises, the oil flows back to the tank through the check valve, the throttle valve is reversed off, when the cylinder falls, the reversing valve is changed to the left or right position (see the structure of the valve), the check valve is reversed off, the oil returns to the tank through the throttle valve, and the speed can be adjusted through the throttle valve.

What type of seal is the cylinder of shaft 50?
You won't know the exact model until you take it apart. Oil seals have O, Y, Yx, KYx, U, UN, UHS, YA, St, Gray, Yamagata, Lei type, etc. It is difficult to know what kind of oil seal the designer chooses. Cylinder oil seal installation method: 1. Receive a fixed number of oil seals. 2. From receiving the oil seal to assembly, it must be kept clean. 3. Before assembly, check the oil seal and measure whether the size of each part of the oil seal is consistent with the size of the shaft and cavity. Before the oil seal is installed, the size of the shaft diameter should be clearly compared with the inner diameter of the oil seal. The inner cavity size should be suitable for the outer diameter width of the oil seal. Check the lip of the oil seal for damage.
