(Costa Rica single rack cylinder,produced by Hengyu Group）

single rack cylinder are widely used in Costa Rica，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed single rack cylinder for customers from Costa Rica.

Introduction to single rack cylinder:

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 wear of the hard chromium plating layer of the single rack cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.

Classification of single rack cylinder: according to the mode of movement it can be divided into linear reciprocating movement type and rotary swing type; According to the effect of liquid pressure, it can be divided into single acting type and double acting type. According to the structure, it can be divided into piston type, plunger type, multistage telescopic sleeve type, pinion and rack type, etc. According to the installation form can be divided into rod, earring, foot, hinge shaft and so on; According to the pressure grade can be divided into 16Mpa, 25Mpa, 31.5Mpa and so on.

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.

Answers to some questions about single rack cylinder:

Why do two hydraulic cylinders lift out of sync?
There may be several situations (do not know the result of the equipment, may not be accurate) 1, whether the slow one is worn 2, whether there is air in the slow cylinder 3, if the two cylinders are supplied by the same oil port, whether the slow joint is blocked (some processing residue will reach a certain oil port under a certain coincidence condition, This situation will not happen if it is not necessarily good before) 4, the oil seal in the slow cylinder leaks, causing the feed oil to leak from the return oil end. Point 4 is most likely because it is invisible and a technical failure. If it is a dual oil feed (separate oil feed), it is also necessary to check the oil supply system and the oil return system (valve type).

Hydraulic cylinder load algorithm?
If it is thrust, load = working pressure x piston area. If it is pulling force, load = working pressure x(piston area - piston rod area).
