Austria push and pull the cylinder

(Austria push and pull the cylinder,produced by Hebei Hengyu company)

push and pull the cylinder are widely used in Austria,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed push and pull the cylinder for customers from Austria.

Introduction to push and pull the cylinder:

push and pull the cylinder piston rod material selection and technical requirements: (I), because there is no special requirements, so use 45 steel as the piston rod material, the design of the piston rod only withstand pressure stress, so no modulation processing; (ii) The coaxial tolerance of the shaft journal and the outer circle of the mounting piston is not greater than 0.01mm, so as to ensure the coaxial degree of the outer circle of the piston rod and the outer circle of the piston, and avoid the stuck phenomenon of the piston and the push and pull the cylinder, the piston rod and the guide. The vertical tolerance between the end face of the mounting piston and the axis of the piston rod is not more than 0.04mm/100mm to ensure that the piston installation does not produce skew; (iii) The outer circle of the piston rod should pay attention to the roughness; (iv) Because it is operated under low load conditions, surface treatment is omitted.

When the push and pull the cylinder is in use, ensure that the push and pull the cylinder and the surrounding environment should be clean. The tank should be sealed to prevent contamination. Pipelines and fuel tanks should be cleaned to prevent falling off the oxide sheet and other debris. Clean with lint-free cloth or special paper. Twine and binder should not be used as sealing materials. Hydraulic oil according to the design requirements, pay attention to the change of oil temperature and oil pressure. When there is no load, unscrew the exhaust bolt for exhaust.

The cavitation of the push and pull the 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 push and pull the 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.

We can not just consider the price and ignore the quality when we purchase the push and pull the cylinders. Now some manufacturers produce unqualified products in order to reduce costs, the piston rod is not adjusted, the rod coating is not enough, the push and pull the cylinder finish can not reach, the guide sleeve should use copper, but instead of ductile iron, although the cost is reduced, the quality of the push and pull the cylinder is not required.

Answers to some questions about push and pull the 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.

What is the thin cylinder used for?
The principle is no different from ordinary cylinders, that is, the installation space is small, the formation is small, and it is suitable for some special occasions. For example, the space is compact and the place of small travel is used.
