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

single rack cylinder are widely used in Angola，because of long service life，smooth movement，high work efficiency.So our company has designed single rack cylinder for customers from Angola.

Introduction to single rack cylinder:

The piston seal of the single rack cylinder is the main element to prevent leakage in the single rack cylinder. For the lip seal, it should focus on checking whether the lip edge is bruised and worn, and for the combination seal, it should focus on checking the wear of the sealing surface, and then determine whether the seal can be used. In addition, it is necessary to check whether the static seal between the piston and the piston rod is crushed. The piston rod seal should focus on checking the wear of the seals and supporting rings.

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.

Repair method of small range wear of oil single rack cylinder: 1. Use oxygen-acetylene flame to bake the scratched part (master the temperature, avoid surface annealing), bake the oil on the metal surface all the year round until no sparks splash; 2. The scratched part is treated with an Angle grinder, the grinding depth is more than 1 mm, and the groove is polished along the guide rail, preferably a dovetail groove. Scratch both ends of the drilling deeper, change the force situation; 3. Clean the surface with absorbent cotton dipped in acetone or anhydrous ethanol.

The machining accuracy of the single rack cylinder depends on the level of equipment, production technology and testing means. single rack cylinder processing methods are commonly used in two ways, one is rough boring - fine boring - rolling, generally with 45# seamless steel pipe, this method of processing quality is good, but the cost is high. Another method is to use 20# cold-drawn seamless steel pipe, and then honing, the cost is lower. The piston rod must be adjusted and straightened before processing, and the coating thickness of the piston rod is generally not less than 0.03mm. The piston must be machined in strict accordance with the groove size and tolerance requirements given in the seal manual.

Answers to some questions about single rack cylinder:

What does cylinder hob125*100 mean?
HOB is a series of hydraulic cylinder products, the use of pressure 14MPA, tie rod structure. 125 refers to the diameter of the cylinder and 100 refers to the stroke. The unit is millimeters.

What is the cause of sound and vibration when the hydraulic cylinder is under load?
The main reason 1) may be that the load machinery has stuck phenomenon, and the resistance is large. 2) The hydraulic oil is not enough, or the filter is blocked by dirty things, and the oil is flooded. 3) There is a problem with the pump.
