Kazakhstan self-locking hydraulic cylinder

(Kazakhstan self-locking hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)

self-locking hydraulic cylinder are widely used in Kazakhstan,because of smooth movement,high work efficiency,excellent fatigue and impact resistance.So our company has designed self-locking hydraulic cylinder for customers from Kazakhstan.

Introduction to self-locking hydraulic cylinder:

The cavitation of the self-locking hydraulic 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 self-locking hydraulic 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.

When the self-locking hydraulic cylinder is kept, do not pay attention to keeping the oil port open, which will produce the condition of accepting foreign bodies at all times, which is absolutely not allowed. Storage must be filled with anti-rust oil or working oil, and plug.

self-locking hydraulic 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 self-locking hydraulic 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.

The self-locking hydraulic cylinder requires that the filtration accuracy of the system is not less than the 80um, and the oil pollution should be strictly controlled, the oil should be kept clean, the performance of the oil should be checked regularly, and the necessary fine filtration and replacement of new working oil should be carried out.

Answers to some questions about self-locking hydraulic cylinder:

How big is a 300-ton cylinder piston?
The rated pressure of the oil pump is 31.5 mpa, the nominal pressure of the hydraulic press is 3150 kN, then the calculated cross-sectional area of the cylinder: S=3150000/31500000=0.1 square meters diameter is: 2* root sign (0.1/3.14) =2*0.178 m =0.356 m 3150 kN hydraulic press is commonly equipped with 31.5 mpa 63 l/min axial piston pump. There are many variable forms of axial piston pump, and the motor size of the pump with the same flow and pressure is not uniform. 31.5 mpa 63 L/min automatic variable pump, can be equipped with 15 kW 4 stage motor; The manual variable pump needs to be equipped with 22 kW 4-stage motor.

How to store hydraulic cylinder?
After cleaning the hydraulic cylinder with diesel or kerosene, apply lubricating oil and wrap it in oil paper, preferably in a wooden box, and store it in a dry and non-corrosive environment. The outer surface and inner surface of the hydraulic cylinder are sprayed with diesel oil, and the inner layer is covered with cloth and the outer coating of anti-rust oil is good. Put it in a dry place, clean it with diesel oil, and then apply a layer of anti-rust inside and outside the butter.
