(Egypt pressure retaining cylinder,produced by Hengyu Hydraulic Cylinder Factory）

pressure retaining cylinder are widely used in Egypt，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed pressure retaining cylinder for customers from Egypt.

Introduction to pressure retaining cylinder:

pressure retaining cylinder can not drive the load troubleshooting: oil pressure is too low. pressure retaining cylinder selection specifications are too small. Leakage in pressure retaining cylinder or associated hydraulic system element.

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 pressure retaining 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.

If the pressure retaining cylinder piston rod is found to be worn, it can be brushed and plated first, then ground, and finally adjust the mating accuracy of the piston rod and the guide sleeve. At this time, the guide sleeve can be properly redrilled or the guide sleeve can be re-turned. When making the above repairs, remember to replace various rubber seals in time.

Because of the slightly complex structure of the buffer pressure retaining cylinder, sometimes there will be problems, such as when the pressure retaining cylinder with the buffer device is started in reverse, the piston often stops temporarily or reverses. Elimination method: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above fault phenomenon will occur when the buffer plunger leaves the end cover. In this regard, the orifice of the check valve should be increased.

Answers to some questions about pressure retaining cylinder:

There are four cylinders in the front top of the dump truck. When the second cylinder is lifted to half the height, it suddenly falls back more than 30 cm or so, and the cylinder continues to lift.
The problem is the cylinder, the second section of the different strength of the heart. When the oil supply resistance is small, the first out, when the power is not moving, the cylinder needs to be strong, because the second section needs to pop it out after a while when the pressure is large, the oil can not keep up, so it falls back, and the oil continues to keep up.

How is the hydraulic cylinder tempered?
The purpose of the tempering treatment is to make the piston rod have comprehensive mechanical properties of strength, hardness, plasticity and toughness, and the internal structure is uniform and fine tempered sorbite, so as to prepare the organization for subsequent surface quenching. The length of the long cylinder piston rod is 3800-4200, and the diameter is Φ90-Φ110mm, so its heating equipment uses a 150KW well resistance furnace or 600KW suspension continuous resistance heating furnace, and the temperature is controlled by two areas. Heat treatment process parameters: in the shaft furnace, a furnace is suspended with 4 pieces, the quenching heating temperature is 830±10℃, and after holding heat for 160min, it is divided into two times for quenching, and two pieces are quenched each time, and the circulating cooling water is used for cooling.
