Romania stern plate hydraulic cylinder

(Romania stern plate hydraulic cylinder,produced by Hengyu Group)

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

Introduction to stern plate hydraulic cylinder:

There are some honeycomb holes in the inner wall of the stern plate hydraulic cylinder, piston or piston rod surface. How is this formed? When we repair the stern plate hydraulic cylinder, we can see that there are some honeycomb holes on the inner wall of the stern plate hydraulic cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the stern plate hydraulic cylinder is targeted to prevent. Is very necessary.

1, the hydraulic machinery should be kept clean, in order to prevent dust and debris from falling into the oil, the tank should be sealed. 2, the oil in the tank should be replaced regularly according to the working condition. When changing the oil, the dirt and impurities accumulated at the bottom of the tank should be removed and the tank should be cleaned. 3, hydraulic oil, oil drums should be set in a clean and safe place to strengthen management. The oil drum, oil filter, oil funnel, oil pipe, etc. used should be kept clean. The oil drums for loading hydraulic oil must be cleaned in advance, and the oil drums should be dedicated and not mixed with other oil drums.

The "O" ring can be used as an auxiliary seal inside the stern plate hydraulic cylinder, and the elastic force of the "O" ring makes the sealing slip ring close to the sealing surface, generating sealing pressure to achieve sealing. When the internal hydraulic pressure increases, the "O" ring will further deform and squeeze the slip ring, thereby increasing the sealing pressure and improving the sealing performance. The structure has the characteristics of low friction coefficient, good wear resistance, automatic compensation for wear and absorption of hard particles in the stern plate hydraulic cylinder, and can be completely sealed.

Before the stern plate hydraulic cylinder is removed, the relief valve should be loosened to reduce the pressure of the hydraulic circuit to zero, and then the power supply should be cut off to stop the hydraulic device. After loosening the oil port piping, the oil plug should be applied to plug the oil port.

Answers to some questions about stern plate hydraulic cylinder:

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.

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.
