Argentina hydraulic cylinder,single rack cylinder manufacturer,single rack cylinder

(Argentina single rack cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to single rack cylinder:

single rack cylinder is the most important part of construction machinery, the traditional processing method is: broaching single rack cylinder block - fine boring single rack cylinder block - grinding single rack cylinder block. The rolling method is: broaching single rack cylinder block - fine boring single rack cylinder block - rolling single rack cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the single rack cylinder block is about 1-2 days, rolling 1 meter of the single rack cylinder 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 RA3.2-6.3 μm before rolling to Ra0.4 ~ 0.8μm, 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 single rack cylinder life is only considered, it is increased by 2 to 3 times, and the boring and rolling process is 3 times more efficient than the grinding process In particular, if you want to make high-quality single rack cylinders, you must take the rolling production process. After the single rack cylinder is rolled, there is no sharp tiny edge on the surface, and long-term motion friction will not damage the seal ring or seal, which is particularly important in the hydraulic industry.

The scar on the sliding surface of the single rack cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the single rack cylinder wall. Therefore, before installation, these scars must be fully repaired.

When the oil pressure of the single rack cylinder inlet is too low to reach the specified value, the leakage situation of the relevant oil system should be checked and the leakage should be eliminated; Check the piston and piston rod seal ring for damage, aging, loose and other phenomena; Check whether the hydraulic pump and pressure valve are faulty.

When installing the single rack cylinder pipe, the pipe should be cleaned after installation, and should not pass through the single rack cylinder block, and the by-pass pipe must be installed in front of the oil port of the single rack cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the single rack cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the single rack cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.

Answers to some questions about single rack cylinder:

What type of seal is the cylinder of shaft 50?
You won't know the exact model until you take it apart. Oil seals have O, Y, Yx, KYx, U, UN, UHS, YA, St, Gray, Yamagata, Lei type, etc. It is difficult to know what kind of oil seal the designer chooses. Cylinder oil seal installation method: 1. Receive a fixed number of oil seals. 2. From receiving the oil seal to assembly, it must be kept clean. 3. Before assembly, check the oil seal and measure whether the size of each part of the oil seal is consistent with the size of the shaft and cavity. Before the oil seal is installed, the size of the shaft diameter should be clearly compared with the inner diameter of the oil seal. The inner cavity size should be suitable for the outer diameter width of the oil seal. Check the lip of the oil seal for damage.

Need a hydraulic cylinder, vertical upward 10 seconds to lift 20 tons of weight up 2 meters, how large cylinder and rod, how much pressure to use the plunger pump and how big?
The first thing to determine the system pressure, let's say 25 mpa, can take into account cost and performance. 1 Cylinder area 20000/250=80 square cm cylinder diameter (80/3.14) squared x2=200 mm 2 cylinder volume 80x200=16000 ml =16 L 3 Required pump flow 16x60/10=96 L/min 4 Power 96x25/55=43 kW 45 kW motor is available.
