(Germany large stroke cylinder,produced by Hebei Hengyu company）

large stroke cylinder are widely used in Germany，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed large stroke cylinder for customers from Germany.

Introduction to large stroke cylinder:

The scar on the sliding surface of the large stroke cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the large stroke cylinder wall. Therefore, before installation, these scars must be fully repaired.

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 large stroke 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.

Most of the failure of the large stroke cylinder is because there is a foreign body in the large stroke cylinder into the failure of the large stroke cylinder, the most problematic is that it is difficult to determine when the foreign body is into the large stroke cylinder. After a foreign body enters, if the outer side of the sliding surface of the piston is equipped with a seal with a lip edge, then the lip edge of the seal can scrape the foreign body when working, which is beneficial to avoid scratching. However, the piston equipped with 0-shaped sealing ring has a sliding surface at both ends, and foreign bodies are sandwiched between this sliding surface, which is easy to form scars.

The large stroke cylinder should not be mixed with foreign objects during assembly, which will cause scars. Before the total assembly of the large stroke cylinder, all parts must be fully removed and cleaned. When the parts are installed with burrs or dirt, foreign objects are easily embedded into the surface of the large stroke cylinder wall due to the stiffness and the weight of the parts, causing scars.

Answers to some questions about large stroke cylinder:

What valve is used to control cylinder expansion?
Mainly use reversing valve, but the details of the control need hydraulic control valve, hydraulic control valve can be divided into direction control valve, pressure control valve, flow control valve. The valve controls the expansion of the cylinder is the direction control valve, that is, the reversing valve. What is the meaning of two-position three-way and three-position four-way of the reversing valve? Usually according to the different working positions that can stay after the spool is moved, it can be divided into: two-position valves, three-position valves and multi-position valves. According to the number of different slide valve channels can be divided into: two-way valve, three-way valve, four-way valve, five-way valve and multi-way valve. The name of the reversing valve is called the multi-position and multi-pass reversing valve according to its working position and the number of channels.

The two cylinders of the bending machine are out of sync?
Check whether the sliding slide is worn, adjust its tightness, so that both sides are consistent, check whether the two cylinder tubing is connected, tighten the flow valve, pressure, let the cylinder air discharge.
