Brazil hydraulic cylinder,shearing machine cylinder manufacturer,shearing machine cylinder(Brazil shearing machine cylinder,produced by Hengyu Hydraulic Cylinder Factory)
shearing machine cylinder are widely used in Brazil,because of simple structure and reliable operation,no transmission clearance,excellent temperature resistance.So our company has designed shearing machine cylinder for customers from Brazil.
The definition of the minimum stable speed refers to the minimum movement speed of the shearing machine cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the shearing machine cylinder that undertakes different work has different requirements for the minimum stable speed.
shearing machine cylinder buffer valve inspection and maintenance: For the valve buffer shearing machine 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.
If the piston rod and shearing machine cylinder are stuck or the shearing machine cylinder is blocked, at this time, no matter how to operate, the shearing machine cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the shearing machine cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.
1, the hydraulic machinery should be kept clean, in order to prevent dust and debris from falling into the oil, the tank should be sealed. 2, the oil in the tank should be replaced regularly according to the working condition. When changing the oil, the dirt and impurities accumulated at the bottom of the tank should be removed and the tank should be cleaned. 3, hydraulic oil, oil drums should be set in a clean and safe place to strengthen management. The oil drum, oil filter, oil funnel, oil pipe, etc. used should be kept clean. The oil drums for loading hydraulic oil must be cleaned in advance, and the oil drums should be dedicated and not mixed with other oil drums.
100 tons press, the cylinder diameter is 250, how much pressure?
100 tons hydraulic press, if it is a single acting hydraulic cylinder, the required oil pressure is the nominal force divided by the cross-sectional area of the cylinder piston. One hundred tons of its pressure is 1000 kN (1000000N), the diameter of the cylinder is 250 mm, its area is the circular rate multiplied by the square of the radius, is 49062.5 square mm, and then the pressure divided by the area of the oil pressure is 20.38MPa. Therefore, a hydraulic pressure of 20.38 mpa is required for a 250 diameter cylinder to obtain 100 tons of pressure.
What hydraulic valve is used to control a cylinder back and forth?
Direction valve is available. Direction valve includes electromagnetic directional valve, manual directional valve, check valve, hydraulic control check valve, the specific choice of which direction valve, you need to see the use of conditions.
