(France stainless steel cylinder,produced by Hengyu Hydraulic Cylinder Factory）
stainless steel cylinder are widely used in France，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed stainless steel cylinder for customers from France.
In the hydraulic system, sometimes the inner layer of the rubber hose is peeled off, so that the oil circuit is on and off, resulting in irregular stainless steel cylinder action. Troubleshooting method: Replace the rubber hose.
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 stainless steel 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.
The scar on the sliding surface of the stainless steel 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 stainless steel cylinder wall. Therefore, before installation, these scars must be fully repaired.
The cavitation of the stainless steel cylinder has a great influence, and to avoid it, it is necessary to use the hydraulic oil reasonably and ensure the quality of the hydraulic oil. If the anti-foam property of the oil is poor, it is easy to produce foam, resulting in cavitation. Secondly, the change frequency of oil pressure is too fast and too high, which will also directly cause the formation of bubbles and accelerate the rupture rate of bubbles. The test shows that the speed of cavitation will be accelerated in the part with high frequency of pressure change. For example, at the inlet and outlet of the stainless steel cylinder, due to the relatively high frequency of pressure changes, the degree of cavitation is also relatively higher than that of other parts. In addition, overheating of the oil will also increase the probability of cavitation.
How big is the pump and motor for 20 tons of hydraulic cylinder?
According to the working pressure of 25 mpa estimate, the cylinder should use 100mm bore, 63mm piston rod, stroke 40mm. According to 30 reciprocating calculation, the flow rate is about 25 liters/minute. The motor power is 11 kW, want to be cheap, use 25SCY14-1B oil pump can be.
How to repair the bent oil cylinder correctly?
If the bending oil cylinder leaks, the most direct way is to replace the seal ring. Most of the sealing rings used by domestic bending machines are made in Taiwan and Japan, so the service life of the sealing ring is still relatively long. If the bending oil cylinder used by the customer leaks oil, then when replacing the seal ring, be sure to choose a high-quality and durable seal ring. In this way, the replaced cylinder will not leak oil for a long time.
