(Belgium lifter hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to lifter hydraulic cylinder:

If the seal of the lifter hydraulic cylinder is abnormal wear, you can check whether the speed control valve is improperly adjusted, resulting in too high back pressure and improper installation of the seal or hydraulic oil contamination. The second is whether there is a foreign body entering the assembly and the quality of the sealing material is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and lifter hydraulic cylinder, and the phenomenon of "pulling the lifter hydraulic cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operation and improvement should be done according to the installation instructions.

lifter hydraulic 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 lifter hydraulic 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 ' lifter hydraulic 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 lifter hydraulic cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The lifter hydraulic cylinder mainly outputs linear motion and force. The lifter hydraulic 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 lifter hydraulic cylinder, plunger lifter hydraulic cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger lifter hydraulic cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.

In use, the lifter hydraulic cylinder should try to avoid the friction iron powder or iron filings formed by buffering the plunger. When the matching gap of the buffer device is small and the transverse load on the piston rod is large, the sintering phenomenon may be caused. These friction iron powder or the metal fragments that have fallen off as a result of sintering will remain in the lifter hydraulic cylinder.

After chrome plating of the piston rod of the lifter hydraulic cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.

Answers to some questions about lifter hydraulic cylinder:

How is the hydraulic cylinder tempered?
The purpose of the tempering treatment is to make the piston rod have comprehensive mechanical properties of strength, hardness, plasticity and toughness, and the internal structure is uniform and fine tempered sorbite, so as to prepare the organization for subsequent surface quenching. The length of the long cylinder piston rod is 3800-4200, and the diameter is Φ90-Φ110mm, so its heating equipment uses a 150KW well resistance furnace or 600KW suspension continuous resistance heating furnace, and the temperature is controlled by two areas. Heat treatment process parameters: in the shaft furnace, a furnace is suspended with 4 pieces, the quenching heating temperature is 830±10℃, and after holding heat for 160min, it is divided into two times for quenching, and two pieces are quenched each time, and the circulating cooling water is used for cooling.

What is the function of the Reza mounted master cylinder?
The role of the Resa-mounted master cylinder is to pump the concrete from the hopper to the delivery pipe and to provide sufficient concrete outlet pressure so that the concrete can reach the specified location.
