(Guatemala shearing machine cylinder,produced by Hengyu Hydraulic Cylinder Factory）
shearing machine cylinder are widely used in Guatemala，because of excellent fatigue and impact resistance，long service life，no need for deceleration device.So our company has designed shearing machine cylinder for customers from Guatemala.
The shearing machine cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the shearing machine cylinder, bite. Elimination method: When installing the shearing machine cylinder, ensure that the axis position of the shearing machine cylinder is consistent with the direction of movement; Make the load borne by the shearing machine cylinder as far as possible through the shearing machine cylinder axis, to avoid the phenomenon of eccentricity.
The shearing machine cylinder requires that the filtration accuracy of the system is not less than the 80um, and the oil pollution should be strictly controlled, the oil should be kept clean, the performance of the oil should be checked regularly, and the necessary fine filtration and replacement of new working oil should be carried out.
Analysis of commonly used seals: The wear ring and slip ring commonly used on the shearing machine cylinder are generally made of polytetrafluoroethylene + graphite, because pure polytetrafluoroethylene is easy to produce plastic creep, which is only suitable for low pressure and low wear resistance conditions. If the sealing ring used is a composite material formed after adding graphite filler, the performance can be effectively improved, the ability to resist plastic creep is increased by 2 to 3 times, the initial deformation caused by the load is reduced by 30 to 60% : the rigidity is increased by 2 to 3 times: the dimensional stability under heat is increased by 2 times, and the hardness is increased by l0 to 15%.
The coordination of the sliding parts of the shearing machine cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.
How big gear pump need to use for 60*100 cylinder?
One cylinder size alone does not determine the size of the pump used. Choose the size of the pump, at least to know 1, the size of the load is how much, by the size of the load and the size of the cylinder and other conditions can be calculated the pressure required by the hydraulic system. 2. Speed of operation. From this speed and cylinder size, the required flow rate of the system is calculated. The relevant parameters of the pump can be selected by the pressure and flow rate to determine what kind of pump is required.
How to judge the leakage in the cylinder?
Common judgment method: In the production site, people make full use of watching, listening, smelling, touching and other sensory ways, by observing that the cylinder can not move or delay the action or feel the oil temperature change, vibration and noise, etc., and then judge whether the cylinder has internal leakage according to experience. Another method commonly used in the field is to extend the cylinder in place to ensure that the cylinder does not have any load and will not retract (to prevent the cylinder from internal leakage accidents), turn off the machine, and then remove the tubing with the rod cavity, and then press the switch that pulls out the cylinder (do not press the wrong switch). If the oil nozzle with the rod cavity drains the cylinder internally, If there's no oil coming out, you have to think about something else going wrong.
