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

retractable cylinder are widely used in Brazil，because of excellent fatigue and impact resistance，simple structure and reliable operation，excellent temperature resistance.So our company has designed retractable cylinder for customers from Brazil.

Introduction to retractable cylinder:

The retractable cylinder can not be used as grounding electrode to avoid electric damage to the piston rod.

retractable cylinder daily maintenance, should focus on checking whether the piston rod surface roughness and shape and position tolerance meet the technical requirements, if the piston rod bending should be calibrated to meet the requirements or according to the physical mapping, manufactured by a professional manufacturer. If the piston rod surface coating wear, slip damage, local spalling can be adopted to remove the coating, re-chrome surface processing process.

Regular maintenance of the retractable cylinder includes: regular tightening, retractable cylinder fastening screws and gland screws, retractable cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the retractable cylinder once a year. Clean regularly, the retractable cylinder is cleaned every other year, and the seals are replaced while cleaning.

The difference between the plunger retractable cylinder and the piston retractable cylinder is that the piston in the retractable cylinder is replaced by a shaft plunger, which is used in hydraulic transmission requiring a long mechanical stroke, and can only input pressure oil from one direction, pressurize in a single direction, and form a thrust to push the plunger to move. The return trip of the plunger depends on the plunger itself to fall, and some rely on the spring to push back to the original position. Usually used plunger type retractable cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.

Answers to some questions about retractable cylinder:

In a hydraulic system, a hydraulic pump has many hydraulic cylinders and hydraulic motors, and these executive components do not coordinate their actions with each other.
A load-sensitive variable pump can be used if these components sometimes need to work simultaneously and the power required is large. The required flow is distributed by the multi-way reversing valve, and the required flow and pressure changes are automatically adjusted by the hydraulic pump. Pressure reducing valves can be used for particularly low pressure circuits. Because you execute more components, the use of quantitative pump will cause a waste of energy, the system heat is large, not suitable.

What are the differences between hydraulic cylinder and pneumatic cylinder, what are their advantages and disadvantages?
Hydraulic Cylinder: small body and large force, constant speed and variable speed (easy to change), the adjustment of output is also convenient, and the degree of freedom of transmission is high. However, maintenance costs and installation costs are high, and there is the trouble of mild oil pollution. Pneumatic Cylinder: easy to control, low price, easy access to energy. But the force is small, and can not achieve the effect of stable speed. The gas-liquid pressurized cylinder has the advantages of both of the above: environmental protection and energy saving, easy control, and simple adjustment. However, the output of the trip has certain restrictions, so it is more suitable for short trips, large output, but also environmental protection and energy saving and low configuration of the occasion. Because the pressure used in the pneumatic system is generally in the range of 0.2-1.0Mpa, the cylinder is not suitable for high power component.
