Paraguay forklift cylinder

(Paraguay forklift cylinder,produced by Hengyu Hydraulic Co., Ltd)

forklift cylinder are widely used in Paraguay,because of excellent fatigue and impact resistance,no need for deceleration device,long service life.So our company has designed forklift cylinder for customers from Paraguay.

Introduction to forklift cylinder:

Improve the service life of the forklift cylinder: it is necessary to maintain the normal clearance of the combined surface of the hydraulic components. When manufacturing or repairing the main parts of the forklift cylinder (such as the forklift cylinder block, piston rod, etc.), the assembly should be carried out in accordance with the tolerance lower limit of the assembly size, which can well reduce the occurrence of cavitation. If cavitation has occurred in the hydraulic components, only metallographic sandpaper polishing technology can be used to remove cavitation pitting and surface carbon deposits, and general fine sandpaper must not be used for polishing After the forklift cylinder is repaired, the hydraulic system should run smoothly for a certain period of time so that the hydraulic oil in the hydraulic system can be fully circulated; If necessary, the forklift cylinder inlet pipe (or return pipe) can be disassembled. Make the hydraulic oil overflow to achieve the effect of single forklift cylinder exhaust.

The commonly used buffer structure of the forklift cylinder is composed of a piston boss and a forklift cylinder head groove. When the piston moves close to the forklift cylinder head, it gradually enters the groove, and the oil in the groove is extruded through the gap between the boss and the groove, which increases the oil return resistance, produces the braking effect and realizes the buffer. Generally, a buffer mechanism should be used when the pressure is above 10MP.

The main role of the forklift cylinder: the forklift cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the forklift cylinder realizes reciprocating motion. The structure of the forklift cylinder has three categories: piston forklift cylinder, plunger forklift cylinder, swing forklift cylinder, piston forklift cylinder and plunger forklift cylinder to achieve reciprocating linear motion, output speed and thrust, swing forklift cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the forklift cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The forklift cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.

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

Answers to some questions about forklift cylinder:

What is the cylinder with rod cavity, what is the rodless cavity.
The rod cavity is the end of the piston rod, the rodless cavity is the end without the piston rod.

How to refuel pneumatic riveting cylinder?
First put the gun flat, that is, horizontally, while pushing the stroke positioning pin and loosen the back cover, rotate to the left for a maximum of five turns, and then use a wrench to loosen the oil sealing screw, slowly add the hydraulic oil and let the air out, fill up to tighten the oil sealing screw. This process of adding hydraulic oil is over.
