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

single rack cylinder are widely used in Qatar，because of no need for deceleration device，smooth movement，simple structure and reliable operation.So our company has designed single rack cylinder for customers from Qatar.

Introduction to single rack cylinder:

When producing oil single rack cylinders, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.

single rack cylinder installation precautions: Before installing the single rack cylinder into the system, the parameters on the single rack cylinder label should be compared with the parameters when ordering. The base of the single rack cylinder must have sufficient stiffness, otherwise the single rack cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.

The coordination of the sliding parts of the single rack cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.

When the single rack cylinder wear is serious, you can try to use an alloy scraper to shave grooves with a depth of more than 1mm on the surface of the slip injury, then clean the grooves with acetone, apply the adjusted TS311 anti-wear repair agent on the polished surface with the single rack cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the single rack cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the single rack cylinder can meet the requirements by grinding. However, the life and reliability of this repair single rack cylinder are not high.

Answers to some questions about single rack cylinder:

Why is a light cylinder less productive than a heavy cylinder at the same oil pressure?
f=ps Under the same pressure, the larger the area, the greater the output, but the maximum pressure can not exceed the system engineering pressure of the cylinder!

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.
