Uzbekistan hydraulic cylinder,single rack cylinder manufacturer,single rack cylinder

(Uzbekistan single rack cylinder,produced by Hebei Hengyu company）

single rack cylinder are widely used in Uzbekistan，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed single rack cylinder for customers from Uzbekistan.

Introduction to single rack cylinder:

The commonly used buffer structure of the single rack cylinder is composed of a piston boss and a single rack cylinder head groove. When the piston moves close to the single rack cylinder head, it gradually enters the groove, and the oil in the groove is extruded through the gap between the boss and the groove, which increases the oil return resistance, produces the braking effect and realizes the buffer. Generally, a buffer mechanism should be used when the pressure is above 10MP.

If it is found that the single rack cylinder lubrication is poor or the single rack cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the single rack cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the single rack cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the single rack cylinder center line. In this way, when the piston works in the single rack cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the single rack cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

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

Protection of the single rack cylinder surface: During the dismantling process, safety protection should be carried out on the single rack cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the single rack cylinder surface. In the process of propulsion, the damaged pipe segments should be prevented from falling and smashing, and the slurry remaining on the surface of the single rack cylinder should be cleaned up in time.

Answers to some questions about single rack cylinder:

The cylinder is moving too fast. I want to slow it down. What can I do?
The hydraulic cylinder is the execution action, and the power source is the hydraulic system. The cylinder speed is too fast, indicating that the system flow is large, the hydraulic system has a hydraulic valve responsible for speed control function, method: 1, by adjusting the speed control valve to reduce the speed; 2, the speed control valve has been adjusted to the lowest, indicating that the hydraulic system design flow is too high, the need to re-configure the hydraulic system according to demand, or the cylinder diameter is changed.

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.
