(India lifting hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)

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

Introduction to lifting hydraulic cylinder:

1, the hydraulic machinery should be kept clean, in order to prevent dust and debris from falling into the oil, the tank should be sealed. 2, the oil in the tank should be replaced regularly according to the working condition. When changing the oil, the dirt and impurities accumulated at the bottom of the tank should be removed and the tank should be cleaned. 3, hydraulic oil, oil drums should be set in a clean and safe place to strengthen management. The oil drum, oil filter, oil funnel, oil pipe, etc. used should be kept clean. The oil drums for loading hydraulic oil must be cleaned in advance, and the oil drums should be dedicated and not mixed with other oil drums.

We can not just consider the price and ignore the quality when we purchase the lifting hydraulic 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 lifting hydraulic 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 lifting hydraulic cylinder is not required.

In recent years, the processing process of the lifting hydraulic cylinder generally adopts the rolling method, which is a pressure finishing processing, which uses the cold plastic characteristics of the metal at room temperature, and uses the rolling tool to exert a certain pressure on the surface of the workpiece, so that the surface metal of the workpiece produces plastic flow, and fills in the low concave trough of the original residue, and the roughness value of the workpiece surface is reduced. Due to the plastic deformation of the rolled surface metal, the surface tissue is cold hardened and the grain is fine, forming a dense fiber, and forming a residual stress layer, and the hardness and strength are increased, thus improving the wear resistance, corrosion resistance and compatibility of the workpiece surface. Rolling is a plastic machining method without cutting.

lifting hydraulic cylinder is the most important part of construction machinery, the traditional processing method is: broaching lifting hydraulic cylinder block - fine boring lifting hydraulic cylinder block - grinding lifting hydraulic cylinder block. The rolling method is: broaching lifting hydraulic cylinder block - fine boring lifting hydraulic cylinder block - rolling lifting hydraulic cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the lifting hydraulic cylinder block is about 1-2 days, rolling 1 meter of the lifting hydraulic 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 lifting hydraulic cylinder increases by 25%. If the lifting hydraulic 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 lifting hydraulic cylinders, you must take the rolling production process. After the lifting hydraulic 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 lifting hydraulic cylinder:

What valve is used to control cylinder expansion?
Mainly use reversing valve, but the details of the control need hydraulic control valve, hydraulic control valve can be divided into direction control valve, pressure control valve, flow control valve. The valve controls the expansion of the cylinder is the direction control valve, that is, the reversing valve. What is the meaning of two-position three-way and three-position four-way of the reversing valve? Usually according to the different working positions that can stay after the spool is moved, it can be divided into: two-position valves, three-position valves and multi-position valves. According to the number of different slide valve channels can be divided into: two-way valve, three-way valve, four-way valve, five-way valve and multi-way valve. The name of the reversing valve is called the multi-position and multi-pass reversing valve according to its working position and the number of channels.

Can a leak in the cylinder cause the hydraulic system to fail?
Leakage in the cylinder can cause the hydraulic system to fail. Cylinder leakage (internal leakage) first affects the controlled action of the hydraulic system can not meet the requirements (such as the movement speed of the cylinder, the insufficient thrust and tension of the cylinder), if the internal leakage of the cylinder is too large, it may also cause the cylinder to be unable to promote the load movement. Second, the existence of internal leakage (internal leakage) of the oil cylinder will lead to the rapid rise (or too high) of the oil temperature of the hydraulic system, and the high oil temperature will not only waste the energy conversion of the system, but also lead to the reduction of the viscosity of the oil, which will accelerate the aging and destruction of the seals such as pumps, valves, cylinders, pipelines, and at the same time, the lubrication effect of the hydraulic oil is reduced, and the production of iron filings that increase the friction of the hydraulic system.
