S.Africa hydraulic cylinder,single rack cylinder manufacturer,single rack cylinder

(S.Africa single rack cylinder,produced by Hengyu Group）

single rack cylinder are widely used in S.Africa，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed single rack cylinder for customers from S.Africa.

Introduction to single rack cylinder:

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.

single rack cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the single rack cylinder head itself is the guide sleeve of the piston rod, the single rack cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the single rack cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

Piston single rack cylinder is widely used in hydraulic transmission. When the single rack cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the single rack cylinder, and uses the pressure difference of hydraulic oil on both sides of the piston to realize the reciprocating movement of the piston. If you want to speed up the forward speed of the piston, the return oil in the single rack cylinder can be controlled by the valve and directly input into the inlet pipe to participate in the work of the piston to achieve rapid movement of the piston, but the thrust of the piston is reduced much.

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:

Does the abbreviation bc stand for bucket cylinder or boom cylinder?
Hydraulic excavator hydraulic cylinder includes boom cylinder, bucket rod cylinder and bucket cylinder three parts, four cylinders. Because of the different naming conventions of major manufacturers, the meaning of BC is also different, for the sake of insurance, you need to consult the manufacturer.

What is a mold core cylinder?
Simple plastic parts can be directly pushed out by the ejector rod after injection molding, complex plastic parts can not be directly pushed out by the ejector rod after injection molding, to make the interference part active, control its position through the cylinder (injection molding into the mold, so that the shape of the plastic parts meet the demand, exit after opening the mold, so that the plastic parts are smoothly pushed out), This kind of cylinder is the mold core cylinder.
