Dominica hydraulic lift cylinder

(Dominica hydraulic lift cylinder,produced by Hengyu Hydraulic Cylinder Factory)

hydraulic lift cylinder are widely used in Dominica,because of long service life,smooth movement,high work efficiency.So our company has designed hydraulic lift cylinder for customers from Dominica.

Introduction to hydraulic lift cylinder:

The pressure of the sliding surface of the hydraulic lift 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 hydraulic lift 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.

Regular maintenance of the hydraulic lift cylinder includes: regular tightening, hydraulic lift cylinder fastening screws and gland screws, hydraulic lift cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the hydraulic lift cylinder once a year. Clean regularly, the hydraulic lift cylinder is cleaned every other year, and the seals are replaced while cleaning.

Classification of hydraulic lift 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.

When the hydraulic lift cylinder is customized, if there are high requirements for the quality of the hydraulic lift cylinder, it is best to use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface of the small crack, preventing the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the hydraulic lift cylinder can be improved. By rolling forming, a cold working hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the inner wall of the hydraulic lift cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.

Answers to some questions about hydraulic lift cylinder:

What is the meaning of cylinder ejection on the injection mold, and what is the difference between cylinder ejection and ordinary ejection?
Usually requires the front die ejection will use the cylinder to drive the thimble plate to achieve the ejection of the thimble. There is also a case that the mold is very large or long, and the balance of the ejector rod of the injection molding machine is not enough, and the cylinder ejector will also be used.

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.
