(New Zealand single rack cylinder,produced by Hengyu Hydraulic Cylinder Factory）

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

Introduction to single rack cylinder:

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

single rack cylinder buffer valve inspection and maintenance: For the valve buffer single rack cylinder, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.

The material of the sliding part of the single rack cylinder piston sintered casting piston will cause sintering phenomenon when subjected to large transverse load. In this case, the sliding part of the piston should be made of copper alloy or welded to such material.

The main role of the single rack cylinder: the single rack 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 single rack cylinder realizes reciprocating motion. The structure of the single rack cylinder has three categories: piston single rack cylinder, plunger single rack cylinder, swing single rack cylinder, piston single rack cylinder and plunger single rack cylinder to achieve reciprocating linear motion, output speed and thrust, swing single rack cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the single rack cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The single rack cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.

Answers to some questions about single rack cylinder:

How is the hydraulic cylinder selected in the mechanical design manual?
First of all, it is necessary to meet your work needs, and the second is to meet the structural space of the cylinder and accessories. Three to consider the other parameters of the cylinder.

What does the maximum output force of the cylinder piston mean?
The maximum output of the cylinder is related to the pressure of the hydraulic system that you link to the cylinder. For example, the rated maximum output thrust of the MOB 50 cylinder is 1.3 tons and the rated pressure is 7Mpa. That is, when the input hydraulic oil pressure of the cylinder reaches 7Mpa, the maximum output thrust of the cylinder is only 0.98 tons. When the input hydraulic pressure is only 5Mpa, the maximum output thrust of the cylinder is 1.3 tons. Because the pressure of the cylinder limit is only 7Mpa, if the oil pressure of the input system exceeds 7Mpa, the cylinder can not withstand the pressure burst, and it is damaged.
