self-locking hydraulic cylinder are widely used in Singapore，because of smooth movement，no need for deceleration device，long service life.So our company has designed self-locking hydraulic cylinder for customers from Singapore.

Introduction to self-locking hydraulic cylinder:

When the oil pressure of the self-locking hydraulic cylinder inlet is too low to reach the specified value, the leakage situation of the relevant oil system should be checked and the leakage should be eliminated; Check the piston and piston rod seal ring for damage, aging, loose and other phenomena; Check whether the hydraulic pump and pressure valve are faulty.

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 self-locking hydraulic 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.

The advantages and disadvantages of the self-locking hydraulic cylinder: the surface of the self-locking hydraulic cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the self-locking hydraulic cylinder through the top heat treatment, high manufacturing precision, belongs to the precision machinery, has a simple structure, stable quality, high mechanical efficiency, easy to achieve automation and many other advantages. However, hydraulic technology also has the shortcomings of oil leakage, oil temperature change affecting the control of running speed, noise, expensive cost and high maintenance cost.

When the initial action of the self-locking hydraulic cylinder is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the self-locking hydraulic cylinder. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.

Answers to some questions about self-locking hydraulic cylinder:

What hydraulic oil does servo cylinder generally use?
The medium used by the cylinder generally depends on the working condition of the use, including pressure, installation environment, sealing material, etc. I think the first thing to consider is the impact of the sealing material. Mineral oil is a good choice if it is not too fire-resistant or used in a high temperature environment. 1, servo cylinder features: closed-loop servo control, control accuracy of 0.01mm; Precise control of thrust, increase pressure sensor, control accuracy up to 1%; It is easy to connect with PLC and other control systems to achieve high precision motion control. Low noise, energy saving, clean, high rigidity, impact resistance, long life, simple operation and maintenance. 2, the servo cylinder can be fault-free in harsh environments, and the protection level can reach IP66.

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.
