Qatar hydraulic cylinder,shearing machine cylinder manufacturer,shearing machine cylinder(Qatar shearing machine cylinder,produced by Hebei Hengyu company)
shearing machine cylinder are widely used in Qatar,because of powerful torque,clever hydraulic energy conversion,simple structure and reliable operation.So our company has designed shearing machine cylinder for customers from Qatar.
The commonly used buffer structure of the shearing machine cylinder is composed of a piston boss and a shearing machine cylinder head groove. When the piston moves close to the shearing machine cylinder head, it gradually enters the groove, and the oil in the groove is extruded through the gap between the boss and the groove, which increases the oil return resistance, produces the braking effect and realizes the buffer. Generally, a buffer mechanism should be used when the pressure is above 10MP.
When the shearing machine cylinder is installed, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the shearing machine cylinder head, earring (or middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent rigid interference and cause unnecessary damage.
Regular maintenance of the shearing machine cylinder includes: regular tightening, shearing machine cylinder fastening screws and gland screws, shearing machine cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the shearing machine cylinder once a year. Clean regularly, the shearing machine cylinder is cleaned every other year, and the seals are replaced while cleaning.
Classification of shearing machine cylinder: according to the mode of movement it can be divided into linear reciprocating movement type and rotary swing type; According to the effect of liquid pressure, it can be divided into single acting type and double acting type. According to the structure, it can be divided into piston type, plunger type, multistage telescopic sleeve type, pinion and rack type, etc. According to the installation form can be divided into rod, earring, foot, hinge shaft and so on; According to the pressure grade can be divided into 16Mpa, 25Mpa, 31.5Mpa and so on.
How to make 4 cylinders balance lifting weight at the same time?
The cost of the synchronous valve is lower, 4 cylinders need 3 synchronous valves, to be precise you can use a synchronous motor, but it is more expensive. There is another way, that is to install a throttle valve in each cylinder, respectively adjust the speed of the cylinder.
How to deal with oil cylinder leakage?
The causes of oil leakage and treatment methods are as follows: (1) The spool is stuck or the valve hole is blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the hydraulic cylinder is prone to misoperation or operation failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check valve body for wear. (2) The piston rod and cylinder are stuck or the hydraulic cylinder is blocked. At this time, no matter how to operate, the hydraulic cylinder does not move or moves very little. At this time, it should be checked whether the piston and piston rod seal is too tight, whether it enters the dirt and colloid precipitate: whether the shaft line of the piston rod and the cylinder is in alignment, and whether the wearing parts and seals are invalid.
