Chile vehicle hydraulic cylinder

(Chile vehicle hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)

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

Introduction to vehicle hydraulic cylinder:

What kind of process is used in the vehicle hydraulic cylinder to make high-quality vehicle hydraulic cylinder products: the body is the main component of the vehicle 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 vehicle 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 vehicle 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 vehicle hydraulic cylinder increases by 25%. If the service life of the vehicle 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. vehicle 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 vehicle 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 vehicle hydraulic cylinder are stuck or the vehicle hydraulic cylinder is blocked. At this time, no matter how to manipulate, the vehicle 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 vehicle hydraulic cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

When using the vehicle hydraulic cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the vehicle hydraulic cylinder block. If the vehicle hydraulic cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the vehicle hydraulic cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the vehicle hydraulic cylinder, so that the working efficiency of the vehicle hydraulic cylinder is reduced.

The repair method of the vehicle hydraulic cylinder: the repair of the vehicle hydraulic cylinder must use brush plating. This is because this repair method can be carried out on site, and the repair effect is good. In this way, loading and transportation can be eliminated to shorten the repair time and improve work efficiency. In addition, the coating obtained by brush plating has good binding force and will not have obvious boundaries. Moreover, the repair surface has high hardness and good wear resistance.

Before the vehicle hydraulic cylinder is removed, the system should be unloaded, the loop pressure is zero, the oil source should be cut off, and the oil port should be blocked after the oil port distribution pipe is loosened.

Answers to some questions about vehicle hydraulic cylinder:

CNC lathe rotary cylinder oil leakage and treatment methods
Oil leakage often occurs when the cylinder (especially the hollow cylinder) of the CNC lathe is installed. First check the cylinder yaw, be sure to reach or close to the required value, generally the cylinder requires the outer beat within 1 wire. Otherwise, too much beating is sure to leak oil. Then check whether the tubing is smoothly downward at a certain Angle, and can not bend. Look at the pipe outlet can not go into the oil level, to a little higher. Otherwise, there's back pressure and it's gonna leak.

How to select the 2.5T bearing cylinder and hydraulic pump?
2,5 ton load is not heavy, you can use the rated pressure of 16 mpa gear pump, neither waste nor save cost, load/pressure = cylinder diameter, preset pressure of 8 mpa, 2500 (kg) /80 (bar) =31.25 square centimeters, in the open =63 mm, cylinder diameter can be selected 63 mm, stroke according to the situation, Hydraulic pump select gear pump, if there is a speed requirement, in order to calculate the displacement, the motor power also needs to determine the displacement of the pump to calculate.
