(Tanzania retractable cylinder,produced by Hengyu Hydraulic Cylinder Factory）

retractable cylinder are widely used in Tanzania，because of clever hydraulic energy conversion，no transmission clearance，powerful torque.So our company has designed retractable cylinder for customers from Tanzania.

Introduction to retractable cylinder:

Disassembly retractable cylinder: When disassembly retractable cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the retractable cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the retractable cylinder.

retractable cylinder and hydraulic station selection: Select the type and structure of the retractable cylinder according to the operation requirements of the main engine. According to the external load force borne by the retractable cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the retractable cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the retractable cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the retractable cylinder, the diameter of the piston and the piston rod.

When the retractable 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 retractable 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.

In order to ensure the service life of the retractable cylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the retractable cylinder, causing damage to the seal and causing leakage in the retractable cylinder. It is required that the filtration accuracy of the system is not less than 80μm, the oil pollution is strictly controlled, the hydraulic oil is kept clean, the performance of the hydraulic oil is regularly checked, and the necessary fine filtration or replacement of the new working hydraulic oil is carried out.

Answers to some questions about retractable cylinder:

Can multiple identical hydraulic cylinders be supplied with the same supply line?
This can be connected, but there is a disadvantage, that is, the hydraulic cylinder with the minimum pressure is extended first, and then the pressure is higher, and then the higher, until all the hydraulic cylinders are extended, which may not meet the requirements of field use.

How to remove the air in hydraulic cylinder?
Connected the cylinder to the system, and reciprocating move with full stroke several times, then the air can be eliminated . There is also a clunky method as follows: first remove the rod cavity oil pipe, connect the rodless cavity oil circuit to extend all the cylinders, and then remove the rodless cavity oil pipe, connect the rod cavity oil pipe and withdraw all the cylinders, and then connect the rodless cavity oil pipe, so that there is no air in the cylinder.
