(lift cargo elevator hydraulic cylinder,produced by Hengyu Group)

lift cargo elevator hydraulic cylinder are widely used ,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed lift cargo elevator hydraulic cylinder for our customers.

Introduction to lift cargo elevator hydraulic cylinder:

The pressure of the sliding surface of the lift cargo elevator hydraulic cylinder piston is too large, resulting in sintering. The piston tilts due to the weight of the piston rod, resulting in the phenomenon of non-stiffness, or the pressure of the sliding surface of the piston rises due to the action of the transverse load, which will cause sintering. In the design of the lift cargo elevator hydraulic cylinder must study its working conditions, the length of the piston and bushing and the size of the clearance must be fully paid attention to.

lift cargo elevator hydraulic cylinder spool stuck or valve hole blocked How to solve: When the flow valve or direction valve spool stuck or valve hole blocked, the lift cargo elevator hydraulic cylinder prone to misoperation or action failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium.

The quality of the lift cargo elevator hydraulic cylinder can not be ignored in the purchase of the lift cargo elevator hydraulic cylinder. The lift cargo elevator hydraulic cylinder is the main component of the lift cargo elevator hydraulic cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. lift cargo elevator hydraulic cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of lift cargo elevator hydraulic cylinder is deep hole processing, which has always troubled the processing personnel.

The definition of the minimum stable speed refers to the minimum movement speed of the lift cargo elevator hydraulic cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the lift cargo elevator hydraulic cylinder that undertakes different work has different requirements for the minimum stable speed.

Answers to some questions about lift cargo elevator 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.

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.
