El Salvador hydraulic cylinder,forklift lift cylinder manufacturer,forklift lift cylinder
(El Salvador forklift lift cylinder,produced by Hengyu Hydraulic Co., Ltd）
forklift lift cylinder are widely used in El Salvador，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed forklift lift cylinder for customers from El Salvador.
In the case of serious wear on the inner surface of the forklift lift cylinder, or when there is a deep longitudinal tensile mark, it should be mapped according to the physical object and re-produced by the professional manufacturer according to the forklift lift cylinder manufacturing process for replacement. The forklift lift cylinder can also be repaired with TS311 antiwear repair agent. TS311 anti-wear repair agent is mainly used for the repair of worn and slipped metal parts.
When installing the forklift lift cylinder, the axial ends of the forklift lift cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the forklift lift cylinder, there is axial expansion. If the two ends of the forklift lift cylinder are fixed, all parts of the forklift lift cylinder will be deformed. When disassembling the forklift lift cylinder, it is strictly forbidden to hammer the forklift lift cylinder and the piston surface, such as the forklift lift cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.
Analysis of commonly used seals: The wear ring and slip ring commonly used on the forklift lift cylinder are generally made of polytetrafluoroethylene + graphite, because pure polytetrafluoroethylene is easy to produce plastic creep, which is only suitable for low pressure and low wear resistance conditions. If the sealing ring used is a composite material formed after adding graphite filler, the performance can be effectively improved, the ability to resist plastic creep is increased by 2 to 3 times, the initial deformation caused by the load is reduced by 30 to 60% : the rigidity is increased by 2 to 3 times: the dimensional stability under heat is increased by 2 times, and the hardness is increased by l0 to 15%.
When producing oil forklift lift cylinders, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.
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.
Cylinder pressure calculation formula
The pressure of the cylinder at work is determined by the load, and the pressure of the physical force is equal to the force divided by the area of action (that is, P=F/S). If you want to calculate the output force of the cylinder, you can calculate it according to the formula: Set the radius of the piston (that is, the cylinder) is R (unit mm) the radius of the piston rod is r (unit mm) the working pressure P (unit MPa) the thrust of the cylinder F push =3.14*R*R*P (unit N) The pulling force of the cylinder F pull =3.14* (R*R-r* R) *P (unit N).
