Bahrain stroke adjustable cylinder

(Bahrain stroke adjustable cylinder,produced by Hebei Hengyu company)

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

Introduction to stroke adjustable cylinder:

The wear of the hard chromium plating layer of the stroke adjustable cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.

stroke adjustable cylinder body inspection: The inner surface of the stroke adjustable cylinder and the piston seal are the main factors causing the leakage in the stroke adjustable cylinder, if the stroke adjustable cylinder has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the stroke adjustable cylinder mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.

The machining accuracy of the stroke adjustable cylinder depends on the level of equipment, production technology and testing means. stroke adjustable 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.

Do not regularly check the damage of the chrome layer of the stroke adjustable cylinder: completely extend the stroke adjustable cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the stroke adjustable cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the stroke adjustable cylinder seal. Welding slag is strictly prohibited on the surface of the stroke adjustable cylinder.

Answers to some questions about stroke adjustable cylinder:

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.

What is the bearing capacity of the HOB cylinder?
The normal specification of HOB is 140 kg pressure, which is more commonly used in the market, and there are clear marks on the cylinder, 210 kg is a strengthened version of HOB, generally customized cylinders are also clearly marked on the above, when the specific use of the cylinder, the maximum use pressure is marked on the cylinder.
