Argentina hydraulic cylinder,lift cargo elevator hydraulic cylinder manufacturer,lift cargo elevator hydraulic cylinder(Argentina lift cargo elevator hydraulic cylinder,produced by Hebei Hengyu company)
lift cargo elevator hydraulic cylinder are widely used in Argentina,because of clever hydraulic energy conversion,simple structure and reliable operation,excellent temperature resistance.So our company has designed lift cargo elevator hydraulic cylinder for customers from Argentina.
We can not just consider the price and ignore the quality when we purchase the lift cargo elevator hydraulic cylinders. Now some manufacturers produce unqualified products in order to reduce costs, the piston rod is not adjusted, the rod coating is not enough, the lift cargo elevator hydraulic cylinder finish can not reach, the guide sleeve should use copper, but instead of ductile iron, although the cost is reduced, the quality of the lift cargo elevator hydraulic cylinder is not required.
The advantages and disadvantages of the lift cargo elevator hydraulic cylinder: the surface of the lift cargo elevator hydraulic cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the lift cargo elevator hydraulic 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.
In the case of serious wear on the inner surface of the lift cargo elevator hydraulic 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 lift cargo elevator hydraulic cylinder manufacturing process for replacement. The lift cargo elevator hydraulic 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.
What kind of process is used in the lift cargo elevator hydraulic cylinder to make high-quality lift cargo elevator hydraulic cylinder products: the body is the main component of the lift cargo elevator hydraulic cylinder, mining single pillar, hydraulic support, gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. Body processing requirements are high, the internal surface roughness requirements are Ra0.4 ~ 0.8&um, the coaxiality, wear resistance requirements are strict. The basic feature of body is deep hole processing, which has always troubled the processing personnel. The lift cargo elevator hydraulic cylinder products of our company mainly use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface micro-cracks and hinder the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the body can be improved. The correct rolling process of the lift cargo elevator hydraulic cylinder block: broaching block - fine boring block - grinding block. The rolling method is: broaching block - fine boring block - rolling block, the process is 3 parts, but the time is compared: grinding 1 meter of the block is about 1-2 days, rolling 1 meter of the block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3um before rolling to RA0.4-0.8&um, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the lift cargo elevator hydraulic cylinder increases by 25%. If the service life of the lift cargo elevator hydraulic cylinder is only considered, it is increased by 2 to 3 times, and the efficiency of the boring and rolling process is about 3 times higher than that of the grinding process. lift cargo elevator hydraulic cylinder misoperation or operation failure may be caused by the following reasons, you can start from these aspects of the investigation: (1) spool stuck or valve hole blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the lift cargo elevator hydraulic cylinder is prone to misoperation or operation failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium. (2) The piston rod and lift cargo elevator hydraulic cylinder are stuck or the lift cargo elevator hydraulic cylinder is blocked. At this time, no matter how to manipulate, the lift cargo elevator hydraulic cylinder does not move or moves very little. 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 lift cargo elevator hydraulic cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.
How to distinguish large cavity and small cavity of excavator rod cylinder ?
Single rod piston cylinder is a form of cylinder that is used relatively most, and the boom, bucket, dozer shovel cylinder are all in this form. Among them, the rodless cavity is also called the large cavity, and the rodless cavity is also called the small cavity. Therefore, the cylinder cavity on the side with the exposed piston rod is the small cavity, and the cylinder cavity on the side without the exposed rod is the large cavity.
What are the main dimensions of the cylinder?
The main dimensions of the cylinder include: cylinder inner diameter, piston cylinder diameter, cylinder length, cylinder wall thickness, stroke, installation distance, etc.
