Ecuador hydraulic cylinder,double rod cylinder manufacturer,double rod cylinder

(Ecuador double rod cylinder,produced by Hebei Hengyu company）

double rod cylinder are widely used in Ecuador，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed double rod cylinder for customers from Ecuador.

Introduction to double rod cylinder:

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

After the double rod cylinder is installed, lubricating grease should be added to the relative moving parts such as earring and middle hinge shaft before trial operation.

Before the double rod cylinder is removed, the system should be unloaded, the loop pressure is zero, the oil source should be cut off, and the oil port should be blocked after the oil port distribution pipe is loosened.

The double rod 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 double rod cylinder, bite. Elimination method: When installing the double rod cylinder, ensure that the axis position of the double rod cylinder is consistent with the direction of movement; Make the load borne by the double rod cylinder as far as possible through the double rod cylinder axis, to avoid the phenomenon of eccentricity.

Answers to some questions about double rod cylinder:

Where is the tension cylinder used in the excavator?
Get off the inside of the frame, behind the guide wheel (steering wheel, guide wheel). Disassemble the track and take the guide wheel out to see the tensioning cylinder (track spring).

Classification and application of cylinders.
Hydraulic cylinder is divided into single acting hydraulic cylinder, double acting cylinder, combined hydraulic cylinder, swing hydraulic cylinder. Single acting cylinder is divided into plunger type hydraulic cylinder, single piston rod hydraulic cylinder, double piston rod hydraulic cylinder, telescopic hydraulic cylinder. Plunger type hydraulic cylinder: the plunger moves only in one direction, and the return stroke is to push the plunger back using its own weight or load. Single piston rod hydraulic cylinder: The piston moves only in one direction, and the return stroke is to push the plunger back using dead weight or load. Double piston rod hydraulic cylinder: both sides of the piston are equipped with piston rods, and pressure oil can only be supplied to one side of the piston. The return stroke usually uses spring force, gravity or external force. Telescopic hydraulic cylinder: It obtains long stroke with short cylinder. The hydraulic oil is pushed out from large to small section by section, and the external force is reduced from small to large.
