Paraguay hydraulic cylinder,rack cylinder manufacturer,rack cylinder
(Paraguay rack cylinder,produced by Hebei Hengyu company）
rack cylinder are widely used in Paraguay，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed rack cylinder for customers from Paraguay.
Most of the failure of the rack cylinder is because there is a foreign body in the rack cylinder into the failure of the rack cylinder, the most problematic is that it is difficult to determine when the foreign body is into the rack cylinder. After a foreign body enters, if the outer side of the sliding surface of the piston is equipped with a seal with a lip edge, then the lip edge of the seal can scrape the foreign body when working, which is beneficial to avoid scratching. However, the piston equipped with 0-shaped sealing ring has a sliding surface at both ends, and foreign bodies are sandwiched between this sliding surface, which is easy to form scars.
When the piston speed of the rack cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the rack cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.
The rack cylinder should not be mixed with foreign objects during assembly, which will cause scars. Before the total assembly of the rack cylinder, all parts must be fully removed and cleaned. When the parts are installed with burrs or dirt, foreign objects are easily embedded into the surface of the rack cylinder wall due to the stiffness and the weight of the parts, causing scars.
If air enters the hydraulic system, the rack cylinder will not operate normally, mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced.
What is the difference between hollow and solid oil cylinders?
Hollow solid cylinder, according to conventional understanding, refers to whether the piston rod is solid or hollow. General ordinary hydraulic cylinder, the piston rod is solid structure. Hollow hydraulic cylinder refers to a hollow piston rod structure of the hydraulic cylinder, see the attached figure. Piston rod hollow function: 1, the piston rod hollow, the middle can be threaded rod. For example, the clamping cylinder with a sawing machine, the piston rod center threading rod, part of the stroke through manual, part of the stroke hydraulic automatic walk. 2, the hollow hole of the piston rod can be used to direct the oil circuit to achieve special oil circuit. 3, the cylinder is relatively large, the piston rod is relatively large, and the stroke is longer, in this case, the piston rod is hollow to reduce the movement friction and lateral force.
Is there a way to make the cylinder stop pushing when it hits something hard during the process of pushing?
The simplest solution is to press the stop switch, this switch has a mechanical type, touch the object on the action or send a stop signal, through the operation of the motor control cylinder; There is also an induction switch, that is, when the hydraulic cylinder expands to the range of the induction switch can sense the signal, it sends a signal to let the motor act, resulting in the corresponding action of the cylinder.
