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

Introduction to lift hydraulic cylinder:

The lift hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or swinging motion). It is simple in structure and reliable in operation. When it is used to achieve reciprocating movement, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in various mechanical hydraulic systems. The output force of the lift hydraulic cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; The lift hydraulic cylinder is basically composed of lift hydraulic cylinder and lift hydraulic cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. Buffer device and exhaust device depending on the specific application, other devices are essential.

When the long-stroke lift hydraulic cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in lift hydraulic cylinder head seal damage, oil leakage, and piston sleep in the lift hydraulic cylinder. The following measures can be taken: increase the piston plan to adjust the piston outer circle and process it into a convex drum, so that the piston can self-position, improve the force situation, and reduce and avoid pulling the lift hydraulic cylinder; The piston and the piston rod are connected with a spherical joint.

The piston rod and guide sleeve function of the lift hydraulic cylinder is crucial: the relative motion pair between the piston rod and the guide sleeve is the main factor causing external leakage, if the chrome layer on the surface of the piston rod is spalling or producing longitudinal tensile marks due to wear, it will directly lead to the failure of the seal.

lift hydraulic 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 lift hydraulic cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the lift hydraulic cylinder. c. The lift hydraulic cylinder seal is extruded, if the O-ring is obviously extruded at the lift hydraulic cylinder seal, replace the lift hydraulic cylinder seal.

Answers to some questions about lift hydraulic cylinder:

How big is the 100t cylinder pump and how big is the motor?
Load is calculated at 15 tons, stroke is calculated at 100 (both take the maximum) 15 tons = 15,000 kg, 15,000/210 bar (21 mpa) =71.42 square centimeters (cylinder area) 71.42/3,14 In the root *2=90,5 the inner diameter of the cylinder can be taken 100 mm. Travel 100 cm, that is, one meter, assuming 10, seconds a back and forth, then it is six times a minute, six meters per minute, then the required flow is,71,42*600 cm (6 meters) =42840 mm =42.84 liters/minute 42.84*21/60=14.9 kilowatts can choose 1450 RPM 4-stage motor 15KW.

The cylinder is moving too fast. I want to slow it down. What can I do?
The hydraulic cylinder is the execution action, and the power source is the hydraulic system. The cylinder speed is too fast, indicating that the system flow is large, the hydraulic system has a hydraulic valve responsible for speed control function, method: 1, by adjusting the speed control valve to reduce the speed; 2, the speed control valve has been adjusted to the lowest, indicating that the hydraulic system design flow is too high, the need to re-configure the hydraulic system according to demand, or the cylinder diameter is changed.
