Switzerland hydraulic lift cylinder

(Switzerland hydraulic lift cylinder,produced by Hengyu Hydraulic Co., Ltd)

hydraulic lift cylinder are widely used in Switzerland,because of excellent fatigue and impact resistance,no need for deceleration device,long service life.So our company has designed hydraulic lift cylinder for customers from Switzerland.

Introduction to hydraulic lift cylinder:

hydraulic lift cylinder piston rod material selection and requirements: ① piston rod is usually made of 45 steel. When there is a large impact force and heavy load transmission, it is made of 40Cr steel. This is to ensure that the piston rod has sufficient working strength. The piston rod is generally designed as a hydraulic lift cylinder, if the diameter is larger, the hollow piston rod can be used. Made of No. 45 seamless steel pipe. ③ When the piston rod is manufactured, the blank should be first forged and conditioned after mechanical rough processing, and the hardness of HB=230 ~ 250. The purpose of conditioning is to improve the machining performance and increase the working strength of the material. ④ The surface roughness Ra of the piston rod after finishing should not be greater than 0.65μm. ⑤ In order to improve the corrosion resistance of the piston rod, the working surface of the rod can be plated with hard chromium. ⑥ The piston rod and the end cap are guided by H8 ' hydraulic lift cylinder piston rod industry standard: piston rod diameter series of national recommended standard GB/T2348-1993. Piston rod thread size series standard GB/T2350-1980. Please refer to execute. There is no industry standard for piston rods Both the hydraulic lift cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The hydraulic lift cylinder mainly outputs linear motion and force. The hydraulic lift cylinder has a variety of forms, according to the different characteristics of its mechanism it can be divided into piston type, plunger type and swing type three categories, according to the mode of action he can be divided into single action and double action. Piston hydraulic lift cylinder, plunger hydraulic lift cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger hydraulic lift cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.

Do not regularly check the damage of the chrome layer of the hydraulic lift cylinder: completely extend the hydraulic lift cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the hydraulic lift cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the hydraulic lift cylinder seal. Welding slag is strictly prohibited on the surface of the hydraulic lift cylinder.

In the hydraulic system, sometimes the inner layer of the rubber hose is peeled off, so that the oil circuit is on and off, resulting in irregular hydraulic lift cylinder action. Troubleshooting method: Replace the rubber hose.

If the seal of the hydraulic lift cylinder is softened and sticky, it may be that the seal is incompatible with the hydraulic oil or the nearby lubricating oil, replace the appropriate seal; If the seal becomes hard and loses elasticity, most of it is because the ambient temperature is too high (more than 80 ° C), make appropriate temperature insulation protection or replace the high temperature seal.

Answers to some questions about hydraulic lift cylinder:

How to limit cylinder push rod rotation?
In general, the push-rod rotation can be limited after the push-rod is connected to the pushed mechanism. For example, the push rod is hinged with the push mechanism, or the push mechanism itself is guided, which can limit the rotation of the push rod.

How many boom cylinders, bucket rod cylinders and bucket cylinders are there in a small single-bucket excavator?
one for bucket, one for forearm, only one piece for a small excavator under the big arm, two pieces for medium and large excavator.
