Chile reciprocating cylinder

(Chile reciprocating cylinder,produced by Hebei Hengyu company)

reciprocating cylinder are widely used in Chile,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed reciprocating cylinder for customers from Chile.

Introduction to reciprocating cylinder:

When the reciprocating cylinder is in use, measures should be added to prevent the intrusion of pollutants. Effective measures should be taken to control the intrusion of pollutants, such as installing high-efficiency air filters in the tank breathing holes, new oil must be filtered, etc., but also must improve the anti-pollution ability of the reciprocating cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil reciprocating cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical reciprocating cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the reciprocating cylinder of the dump truck, construction machinery, work platform and other equipment, and in order to reduce the oil inlet resistance, the flow area should be increased as much as possible, which can effectively reduce the particle pollution from the system.

reciprocating cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the reciprocating cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the reciprocating cylinder. c. The reciprocating cylinder seal is extruded, if the O-ring is obviously extruded at the reciprocating cylinder seal, replace the reciprocating cylinder seal.

In use, the reciprocating cylinder should try to avoid the friction iron powder or iron filings formed by buffering the plunger. When the matching gap of the buffer device is small and the transverse load on the piston rod is large, the sintering phenomenon may be caused. These friction iron powder or the metal fragments that have fallen off as a result of sintering will remain in the reciprocating cylinder.

Analysis of commonly used seals: The wear ring and slip ring commonly used on the reciprocating 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%.

Answers to some questions about reciprocating cylinder:

What are the connection methods of the hydraulic cylinder? The connection modes of the cylinder and the actuator are earring connection, hinge shaft connection, thread connection, etc. The connection modes of tubing and cylinder are threaded connection, flange connection, etc.

When the cylinder is tested, why can't the pressure be maintained with the balance valve?
Because the oil into the oil chamber through the hydraulic lock on the control oil circuit through the other side of the spool, the original valve is designed in this way. It locks the circuit after the oil supply circuit loses pressure, on the contrary, if you keep supplying pressure, it is always in the state of opening the other side of the one-way spool. So this valve can't be used in the test.
