(Guatemala Lifting cylinder,produced by Hengyu Hydraulic Cylinder Factory）

Lifting cylinder are widely used in Guatemala，because of no need for deceleration device，long service life，smooth movement.So our company has designed Lifting cylinder for customers from Guatemala.

Introduction to Lifting cylinder:

Disassembly Lifting cylinder: When disassembly Lifting cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the Lifting cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the Lifting cylinder.

Do not enter foreign bodies when installing the Lifting cylinder block. The place where the installation operation is carried out, the conditions are not good, and foreign bodies can be entered unconsciously. Therefore, the installation site must be cleaned up around, especially the place where the parts are placed must be cleaned, so that there is no dirt.

After the Lifting cylinder is installed, lubricating grease should be added to the relative moving parts such as earring and middle hinge shaft before trial operation.

The Lifting cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure Lifting cylinder can use 20 steel pipe, and the high pressure Lifting cylinder can use 45 steel pipe.

Answers to some questions about Lifting cylinder:

Why should the piston rod of the hydraulic cylinder be so precise? If you hope the cylinder has a long service cycle, then all parts need to be high-precision, not only the piston rod, but also the cylinder, the sealing groove, the surface roughness, the cylinder looks very simple. Any hydraulic factory can produce the cylinder, but the good cylinder is difficult to produce.

What is the cause of the sound of the excavator arm cylinder?
Hydraulic excavator cylinder includes boom cylinder, bucket rod cylinder and bucket cylinder, four cylinders. The sound of boom cylinder may be the wear of hydraulic cylinder block bushing, piston rod bushing and shaft pin. The main reason: poor lubrication, followed by improper clearance in the assembly process. Countermeasures: (1) Strictly lubricate each shaft pin at least once every 8 hours when the excavator is initially used for 100 hours and under harsh conditions; In other working conditions, lubricate each pin at least once every 50 hours. (2) If the lubricating oil passage is found to be blocked, it must be stopped for rectification. (3) Require assembly, replacement of all parts of the shaft pin, bushing strictly comply with the assembly testing standards and operating procedures.
