(Australia tailboard balance cylinder,produced by Hengyu Hydraulic Co., Ltd）

tailboard balance cylinder are widely used in Australia，because of smooth movement，high work efficiency，clever hydraulic energy conversion.So our company has designed tailboard balance cylinder for customers from Australia.

Introduction to tailboard balance cylinder:

If the piston rod and tailboard balance cylinder are stuck or the tailboard balance cylinder is blocked, at this time, no matter how to operate, the tailboard balance cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the tailboard balance cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

The definition of the minimum starting pressure of the tailboard balance cylinder refers to the minimum working pressure of the tailboard balance cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the tailboard balance cylinder parts and the size of the sealing friction.

tailboard balance cylinder piston rod material introduction: In general, we use 45 steel to produce tailboard balance cylinder piston rod. It has a large impact force when it is used, and some good performance steel are also used in the heavy load transmission. In order to have enough work intensity when using, and can ensure normal use, this is still more critical to have a detailed understanding of the material.

tailboard balance cylinder is the most important part of construction machinery, the traditional processing method is: broaching tailboard balance cylinder block - fine boring tailboard balance cylinder block - grinding tailboard balance cylinder block. The rolling method is: broaching tailboard balance cylinder block - fine boring tailboard balance cylinder block - rolling tailboard balance cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the tailboard balance cylinder block is about 1-2 days, rolling 1 meter of the tailboard balance cylinder block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3 μm before rolling to Ra0.4 ~ 0.8μm, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the tailboard balance cylinder increases by 25%. If the tailboard balance cylinder life is only considered, it is increased by 2 to 3 times, and the boring and rolling process is 3 times more efficient than the grinding process In particular, if you want to make high-quality tailboard balance cylinders, you must take the rolling production process. After the tailboard balance cylinder is rolled, there is no sharp tiny edge on the surface, and long-term motion friction will not damage the seal ring or seal, which is particularly important in the hydraulic industry.

Answers to some questions about tailboard balance cylinder:

Classification and application of cylinders.
Hydraulic cylinder is divided into single acting hydraulic cylinder, double acting cylinder, combined hydraulic cylinder, swing hydraulic cylinder. Single acting cylinder is divided into plunger type hydraulic cylinder, single piston rod hydraulic cylinder, double piston rod hydraulic cylinder, telescopic hydraulic cylinder. Plunger type hydraulic cylinder: the plunger moves only in one direction, and the return stroke is to push the plunger back using its own weight or load. Single piston rod hydraulic cylinder: The piston moves only in one direction, and the return stroke is to push the plunger back using dead weight or load. Double piston rod hydraulic cylinder: both sides of the piston are equipped with piston rods, and pressure oil can only be supplied to one side of the piston. The return stroke usually uses spring force, gravity or external force. Telescopic hydraulic cylinder: It obtains long stroke with short cylinder. The hydraulic oil is pushed out from large to small section by section, and the external force is reduced from small to large.

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.
