Hungary tension cylinder

(Hungary tension cylinder,produced by Hengyu Group)

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

Introduction to tension cylinder:

If the seal of the tension 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 tension cylinder, and the phenomenon of "pulling the tension 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.

When installing the piston rod, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the tension cylinder head adn the earring (or the middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent the phenomenon of rigid interference and causing unnecessary damage.

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

Factors that should be considered when selecting the oil seal in the tension cylinder: some specific factors should be taken into account when selecting the oil seal in the tension cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: tension cylinder diameter, piston rod diameter, piston rod and piston groove size, tension cylinder working pressure, tension cylinder movement speed, hydraulic system oil temperature and tension cylinder working environment.

Answers to some questions about tension cylinder:

How big is the pump and motor for 20 tons of hydraulic cylinder?
According to the working pressure of 25 mpa estimate, the cylinder should use 100mm bore, 63mm piston rod, stroke 40mm. According to 30 reciprocating calculation, the flow rate is about 25 liters/minute. The motor power is 11 kW, want to be cheap, use 25SCY14-1B oil pump can be.

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.
