(Latvia stacker cylinder,produced by Hebei Hengyu company）

stacker cylinder are widely used in Latvia，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed stacker cylinder for customers from Latvia.

Introduction to stacker cylinder:

When the hydraulic oil is not pumped into the stacker cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the stacker cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.

The method of sleeve stacker cylinder to improve the processing quality: there is a big gap in the service life of post-plating polishing and post-plating polishing, especially in mass production. Strictly clean the flying edge and burr of mechanical components, especially the edge of the sealing groove, and the tiny metal burr, strictly clean before assembly. The surface fatigue strength and stress corrosion resistance of the stacker cylinder can be significantly improved by rolling in the finishing of the inner holes of the stacker cylinder. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.

The cavitation of the stacker 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 stacker 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.

The daily inspection of the stacker cylinder includes: checking the connection of the stacker cylinder and the pipe joint for leaks. Check the stacker cylinder rod for leaks. Check the stacker cylinder connection for leaks. When the stacker cylinder moves, the work is normal and smooth. Whether the stacker cylinder has internal leakage.

Answers to some questions about stacker cylinder:

How to disassemble the cylinder?
Generally speaking, it is not difficult to disassemble the hydraulic cylinder, as long as you are careful, but you often encounter some small trouble in the disassembly process, because the disassembly process is not correct. In fact, this can be avoided, as long as you follow below points. 1. Before removing the hydraulic cylinder, the hydraulic circuit should be relieved of pressure, otherwise, when the oil pipe connected with the cylinder is loosened, the high-pressure oil in the circuit will be rapidly ejected. When the hydraulic pressure comes back, the handwheel or pressure regulating screw at the relief valve should be loosened first, so that the pressure oil is unloaded, and then the power supply or power source is cut off, so that the hydraulic device stops running. 2. Disassembly should prevent damage to the top thread of the piston rod, the oil thread and the chrome layer on the piston rod surface.

How does the hydraulic solenoid valve realize that the cylinder stops at any position?
Use an O-type medium function solenoid directional valve, or use a Y-type solenoid directional valve and a hydraulically controlled check valve.
