unidirectional cylinder are widely used in Colombia，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed unidirectional cylinder for customers from Colombia.

Introduction to unidirectional cylinder:

The viscosity of the working oil used in the unidirectional cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.

Piston unidirectional cylinder is widely used in hydraulic transmission. When the unidirectional cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the unidirectional cylinder, and uses the pressure difference of hydraulic oil on both sides of the piston to realize the reciprocating movement of the piston. If you want to speed up the forward speed of the piston, the return oil in the unidirectional cylinder can be controlled by the valve and directly input into the inlet pipe to participate in the work of the piston to achieve rapid movement of the piston, but the thrust of the piston is reduced much.

The advantages and disadvantages of the unidirectional cylinder: the surface of the unidirectional cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the unidirectional cylinder through the top heat treatment, high manufacturing precision, belongs to the precision machinery, has a simple structure, stable quality, high mechanical efficiency, easy to achieve automation and many other advantages. However, hydraulic technology also has the shortcomings of oil leakage, oil temperature change affecting the control of running speed, noise, expensive cost and high maintenance cost.

If the piston rod and unidirectional cylinder are stuck or the unidirectional cylinder is blocked, at this time, no matter how to operate, the unidirectional cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the unidirectional cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

Answers to some questions about unidirectional cylinder:

What are the problems that cause hydraulic cylinder shaking?
1, the oil supply is not smooth, the hydraulic oil filter is half blocked. 2. The oil level in the oil storage tank is lower than the minimum oil level. 3, there is air in the hydraulic system. 4, the supply oil pump is damaged or not working properly. 5, the hydraulic oil is not replaced for a long time.

The pressure gauge of the hydraulic station reaches 20MPa. How many tons of weight can the hydraulic cylinder lift? How to convert?
20Mpa=200kg/cm^2 The weight of the cylinder with a cross-sectional area of 1 square centimeter can be lifted is 200kg, so F=200X3.14X (125/2) ^2 =24531kg =24.5 tons.
