(Tunisia electric forklift hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）

electric forklift hydraulic cylinder are widely used in Tunisia，because of long service life，smooth movement，high work efficiency.So our company has designed electric forklift hydraulic cylinder for customers from Tunisia.

Introduction to electric forklift hydraulic cylinder:

The definition of the minimum starting pressure of the electric forklift hydraulic cylinder refers to the minimum working pressure of the electric forklift hydraulic cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the electric forklift hydraulic cylinder parts and the size of the sealing friction.

The electric forklift hydraulic cylinder is mainly composed of body, piston, piston rod, electric forklift hydraulic cylinder head, electric forklift hydraulic cylinder bottom, piston rod head and related auxiliary devices. The piston divides the electric forklift hydraulic cylinder into two chambers, and moves reciprocally in the electric forklift hydraulic cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the electric forklift hydraulic cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the electric forklift hydraulic cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the electric forklift hydraulic cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the electric forklift hydraulic cylinder bottom and the electric forklift hydraulic cylinder head is serious, so the buffer deceleration should be set at both ends of the electric forklift hydraulic cylinder The working medium of the electric forklift hydraulic cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; electric forklift hydraulic cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the electric forklift hydraulic cylinder: The buffer structure of the electric forklift hydraulic cylinder is to prevent the piston from colliding with the electric forklift hydraulic cylinder head at the end of the stroke.

The electric forklift hydraulic cylinder should be avoided for a long time without use, if it is indeed idle for a long time for some reason, it should also be regularly turned on for empty operation, so that its parts can be fully lubricated, so as to avoid rust on the working surface and affect the normal work in the future. (If it cannot be turned on and run, a small amount of lubricating oil can be applied on its outer surface for protection) ' The use of the electric forklift hydraulic cylinder should pay attention to: the operation should be as far away from the electric forklift hydraulic cylinder as possible, to avoid falling objects, knocking, rubbing the electric forklift hydraulic cylinder coating. When cleaning the electric forklift hydraulic cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the electric forklift hydraulic cylinder when the oil temperature exceeds 70 ° C.

The machining accuracy of the electric forklift hydraulic cylinder depends on the level of equipment, production technology and testing means. electric forklift hydraulic cylinder processing methods are commonly used in two ways, one is rough boring - fine boring - rolling, generally with 45# seamless steel pipe, this method of processing quality is good, but the cost is high. Another method is to use 20# cold-drawn seamless steel pipe, and then honing, the cost is lower. The piston rod must be adjusted and straightened before processing, and the coating thickness of the piston rod is generally not less than 0.03mm. The piston must be machined in strict accordance with the groove size and tolerance requirements given in the seal manual.

Answers to some questions about electric forklift hydraulic cylinder:

What is the meaning of cylinder ejection on the injection mold, and what is the difference between cylinder ejection and ordinary ejection?
Usually requires the front die ejection will use the cylinder to drive the thimble plate to achieve the ejection of the thimble. There is also a case that the mold is very large or long, and the balance of the ejector rod of the injection molding machine is not enough, and the cylinder ejector will also be used.

Is it good or bad for the hydraulic cylinder working in the limit stroke position?
It is not good for the hydraulic cylinder working in the limit stroke position. Generally, when the cylinder is used in the limit stroke, the oil in the cylinder will form a backflow back pressure impact on the piston and guide sleeve seals. If the limit is not accurate, it is easy to cause collision damage. It is recommended to leave a buffer of ten to twenty centimeters.
