Bulgaria servo hydraulic cylinder

(Bulgaria servo hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory)

servo hydraulic cylinder are widely used in Bulgaria,because of high work efficiency,excellent fatigue and impact resistance,no need for deceleration device.So our company has designed servo hydraulic cylinder for customers from Bulgaria.

Introduction to servo hydraulic cylinder:

Classification of servo hydraulic cylinder: according to the mode of movement it can be divided into linear reciprocating movement type and rotary swing type; According to the effect of liquid pressure, it can be divided into single acting type and double acting type. According to the structure, it can be divided into piston type, plunger type, multistage telescopic sleeve type, pinion and rack type, etc. According to the installation form can be divided into rod, earring, foot, hinge shaft and so on; According to the pressure grade can be divided into 16Mpa, 25Mpa, 31.5Mpa and so on.

Causes and countermeasures of oil servo hydraulic cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the servo hydraulic cylinder will lead to premature wear of the piston seal, replace the piston seal; If the servo hydraulic cylinder is visibly scarred, the servo hydraulic cylinder must be replaced. It can be pressurized at one end of the servo hydraulic cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most servo hydraulic cylinder piston drift may not come from the servo hydraulic cylinder, the above method to determine the servo hydraulic cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.

There are some honeycomb holes in the inner wall of the servo hydraulic cylinder, piston or piston rod surface. How is this formed? When we repair the servo hydraulic cylinder, we can see that there are some honeycomb holes on the inner wall of the servo hydraulic cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the servo hydraulic cylinder is targeted to prevent. Is very necessary.

The difference between the plunger servo hydraulic cylinder and the piston servo hydraulic cylinder is that the piston in the servo hydraulic cylinder is replaced by a shaft plunger, which is used in hydraulic transmission requiring a long mechanical stroke, and can only input pressure oil from one direction, pressurize in a single direction, and form a thrust to push the plunger to move. The return trip of the plunger depends on the plunger itself to fall, and some rely on the spring to push back to the original position. Usually used plunger type servo hydraulic cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.

Answers to some questions about servo hydraulic cylinder:

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.

What is the difference between hydraulic cylinder self-adjusting buffer and adjustable buffer?
If it is the buffer device inside the cylinder, then there are 4 basic forms, cylindrical buffer device, conical buffer device, variable throttle and adjustable flow groove. The biggest difference between the first three and the latter is that the latter can be adjusted through the external thimble to change the buffer strength, the first three mainly rely on the buffer device and buffer groove form to achieve the buffer (among them, the first type of buffer strength will not change, and the buffer strength of the two and three forms of buffer devices can be gradually increased).
