Turkmenistan hydraulic cylinder,hydraulic servo cylinder manufacturer,hydraulic servo cylinder

(Turkmenistan hydraulic servo cylinder,produced by Hebei Hengyu company）

hydraulic servo cylinder are widely used in Turkmenistan，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed hydraulic servo cylinder for customers from Turkmenistan.

Introduction to hydraulic servo cylinder:

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

How the cavitation of the hydraulic servo cylinder is formed: With the gradual rise of pressure, the gas in the oil will become bubbles, when the pressure rises to a certain limit value, these bubbles will break under the action of high pressure, so that the high temperature and high pressure gas will quickly act on the surface of the parts, resulting in cavitation of the hydraulic servo cylinder, resulting in corrosive damage to the parts.

hydraulic servo cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the hydraulic servo cylinder head itself is the guide sleeve of the piston rod, the hydraulic servo 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 hydraulic servo cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

If the seal of the hydraulic servo 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 hydraulic servo cylinder, and the phenomenon of "pulling the hydraulic servo 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.

Answers to some questions about hydraulic servo cylinder:

Servo cylinder control principle
The electro-hydraulic pulse servo cylinder is composed of a stepper motor, a three-position four-way servo valve, a mechanical feedback device (a wire carrier) and an oil lever. When the stepper motor gets a pulse signal, its output shaft rotates 1.5 or 3 degrees, the servo valve spool drives the wire to rotate at the same time, the valve spool moves and opens the reversing cylinder to output pressure oil, the piston moves and drives the lead screw to reverse rotate the valve spool back to the original position, and the servo valve stops output pressure oil in the center. At this time, the cylinder moves 0.1 or 0.2mm stroke, and the displacement and speed of the cylinder travel are determined according to the given value of the electrical pulse.

How to calculate the hydraulic cylinder pressure? How much pressure can put up how much weight?
If you want to calculate the pressure of the cylinder, you must know the inner diameter of the cylinder, if the piston rod is needed to lift the weight, it should be: cylinder (no piston rod end) pressure = load (4000N) ÷{(PI /4)X the square of the cylinder diameter (mm) ", it has nothing to do with the piston rod diameter, the rod diameter of the piston rod is only related to the stability of the cylinder. The pressure inside the cylinder should be p=F/S=400×10/(3.14×(0.5×25)×(0.5×25))=8.15MPa which means that you need to provide at least that much pressure to complete the operation.
