(Burma spring return cylinder,produced by Hengyu Hydraulic Co., Ltd）

spring return cylinder are widely used in Burma，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed spring return cylinder for customers from Burma.

Introduction to spring return cylinder:

The machining accuracy of the spring return cylinder depends on the level of equipment, production technology and testing means. spring return cylinder processing methods are commonly used in two ways, one is rough boring - fine boring - rolling, generally with 45# seamless steel pipe, this method of processing quality is good, but the cost is high. Another method is to use 20# cold-drawn seamless steel pipe, and then honing, the cost is lower. The piston rod must be adjusted and straightened before processing, and the coating thickness of the piston rod is generally not less than 0.03mm. The piston must be machined in strict accordance with the groove size and tolerance requirements given in the seal manual.

The oil spring return cylinder is a part of the hydraulic system, in the hydraulic system, to reasonably design the heat dissipation system, to prevent the oil temperature is too high is the key to keep the hydraulic oil temperature normal. The temperature of the system should be kept in a suitable range to reduce the energy released when the bubble bursts. While not affecting the normal circulation of the coolant, a certain amount of anti-corrosion additives can be appropriately added to inhibit rust. When operating the hydraulic system, we should strive to be stable, not too fast, too strong, and try to reduce the impact of hydraulic oil on hydraulic components.

spring return cylinder and hydraulic station selection: Select the type and structure of the spring return cylinder according to the operation requirements of the main engine. According to the external load force borne by the spring return cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the spring return cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the spring return cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the spring return cylinder, the diameter of the piston and the piston rod.

The internal leakage of the spring return cylinder is an important indicator to measure the quality of the spring return cylinder: the internal leakage of the spring return cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the spring return cylinder, so that the spring return cylinder can not accurately and stably stop in a certain position of the spring return cylinder, so it is one of the main indicators of the spring return cylinder.

Answers to some questions about spring return cylinder:

How to deal with oil cylinder leakage?
The causes of oil leakage and treatment methods are as follows: (1) The spool is stuck or the valve hole is blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the hydraulic cylinder is prone to misoperation or operation failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check valve body for wear. (2) The piston rod and cylinder are stuck or the hydraulic cylinder is blocked. At this time, no matter how to operate, the hydraulic cylinder does not move or moves very little. At this time, it should be checked whether the piston and piston rod seal is too tight, whether it enters the dirt and colloid precipitate: whether the shaft line of the piston rod and the cylinder is in alignment, and whether the wearing parts and seals are invalid.

Structural characteristics of the plunger cylinder? (1) The plunger hydraulic cylinder is a single-acting hydraulic cylinder, which can only move in one direction by hydraulic pressure, and the return trip of the plunger depends on other external forces or the weight of the plunger; (2) The plunger is only supported by the cylinder liner and is not in contact with the cylinder liner, so the cylinder liner is easy to process, so it is suitable for long stroke hydraulic cylinder; (3) the total pressure of the plunger during work, so it must have sufficient stiffness; (4) The weight of the plunger is often large, and it is easy to sag due to its own weight when placed horizontally, resulting in wear of the seals and guide side, so its vertical use is more favorable.
