(Angola stern plate hydraulic cylinder,produced by Hebei Hengyu company）

stern plate hydraulic cylinder are widely used in Angola，because of excellent temperature resistance，powerful torque，no need for deceleration device.So our company has designed stern plate hydraulic cylinder for customers from Angola.

Introduction to stern plate hydraulic cylinder:

Piston stern plate hydraulic cylinder is widely used in hydraulic transmission. When the stern plate hydraulic cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the stern plate hydraulic cylinder, and uses the pressure difference of hydraulic oil on both sides of the piston to realize the reciprocating movement of the piston. If you want to speed up the forward speed of the piston, the return oil in the stern plate hydraulic cylinder can be controlled by the valve and directly input into the inlet pipe to participate in the work of the piston to achieve rapid movement of the piston, but the thrust of the piston is reduced much.

stern plate hydraulic cylinder use should try to avoid sealing belt into the stern plate hydraulic cylinder. As a simple sealing material, polytetrafluoroethylene plastic sealing tape is often used in installation and inspection, and if the winding method of the linear and ribbon-shaped sealing material is wrong, the sealing tape will be cut off and enter the stern plate hydraulic cylinder. The wire belt seal will not have any effect on the winding of the sliding part, but it will cause the check valve of the stern plate hydraulic cylinder to fail to operate or the buffer regulating valve can not be adjusted to the end. For the circuit, it may cause the action of the reversing valve, the relief valve and the reducing valve to fail.

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

In order to ensure the service life of the stern plate hydraulic cylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the stern plate hydraulic cylinder, causing damage to the seal and causing leakage in the stern plate hydraulic cylinder. It is required that the filtration accuracy of the system is not less than 80μm, the oil pollution is strictly controlled, the hydraulic oil is kept clean, the performance of the hydraulic oil is regularly checked, and the necessary fine filtration or replacement of the new working hydraulic oil is carried out.

Answers to some questions about stern plate hydraulic 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.

For a cylinder with a piston diameter of 100mm and a system pressure of 10MPa, what is the thrust?
Thrust is 7850 kg. Piston area A= πR^2=7850 square mm =78.5 square cm 10MPa = 100kg/cm^2 "^2" is square F = A x P =78.5 x 100=7850 kg.
