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

single rack cylinder are widely used in Italy，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed single rack cylinder for customers from Italy.

Introduction to single rack cylinder:

single rack cylinder daily maintenance, should focus on checking whether the piston rod surface roughness and shape and position tolerance meet the technical requirements, if the piston rod bending should be calibrated to meet the requirements or according to the physical mapping, manufactured by a professional manufacturer. If the piston rod surface coating wear, slip damage, local spalling can be adopted to remove the coating, re-chrome surface processing process.

When the single rack cylinder is installed on the main engine, the oil port piping part and the guide sleeve should be checked for oil leakage in the running test, and the earring and the middle hinge shaft bearing should be refueled.

When using the single rack cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the single rack cylinder block. If the single rack cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the single rack cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the single rack cylinder, so that the working efficiency of the single rack cylinder is reduced.

The method of sleeve single rack cylinder to improve the processing quality: there is a big gap in the service life of post-plating polishing and post-plating polishing, especially in mass production. Strictly clean the flying edge and burr of mechanical components, especially the edge of the sealing groove, and the tiny metal burr, strictly clean before assembly. The surface fatigue strength and stress corrosion resistance of the single rack cylinder can be significantly improved by rolling in the finishing of the inner holes of the single rack cylinder. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.

Answers to some questions about single rack cylinder:

Structural characteristics of the plunger cylinder? (1) The plunger hydraulic cylinder is a single-acting hydraulic cylinder, which can only move in one direction by hydraulic pressure, and the return trip of the plunger depends on other external forces or the weight of the plunger; (2) The plunger is only supported by the cylinder liner and is not in contact with the cylinder liner, so the cylinder liner is easy to process, so it is suitable for long stroke hydraulic cylinder; (3) the total pressure of the plunger during work, so it must have sufficient stiffness; (4) The weight of the plunger is often large, and it is easy to sag due to its own weight when placed horizontally, resulting in wear of the seals and guide side, so its vertical use is more favorable.

Why can't the hydraulic cylinder be replaced with water?
Hydraulic oil for hydraulic transmission has a variety of requirements for viscosity, density, flow rate, and temperature, which are not available for water.
