(Azerbaijan plunger type cylinder,produced by Hebei Hengyu company）

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

Introduction to plunger type cylinder:

The plunger type cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure plunger type cylinder can use 20 steel pipe, and the high pressure plunger type cylinder can use 45 steel pipe.

If the plunger type cylinder slips or crawls, please check whether there is astringency inside the plunger type cylinder, because the internal parts of the plunger type cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, the action resistance is too large, so that the piston speed of the plunger type cylinder changes with the different stroke position, and the slip or crawl occurs. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the plunger type cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings.

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

The wear of the hard chromium plating layer of the plunger type 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.

Answers to some questions about plunger type cylinder:

What components can control cylinder rising and falling speed and the speed is adjustable?
A throttle or special solenoid valve is required. The reversing valve can choose the three-position reversing valve with P-type middle function. When rising, the reversing valve can be changed to the middle position to achieve differential connection and the fastest speed. Add a combination valve one-way throttle valve in the oil return circuit, connection mode: when the cylinder rises, the oil flows back to the tank through the check valve, the throttle valve is reversed off, when the cylinder falls, the reversing valve is changed to the left or right position (see the structure of the valve), the check valve is reversed off, the oil returns to the tank through the throttle valve, and the speed can be adjusted through the throttle valve.

How to control the speed of the cylinder?
High demand control, it is necessary to use servo closed-loop control, you can adjust the speed at will. Reference: Hydrodynamic Motion Control Practical Design Guide.
