Italy hydraulic cylinder,reset cylinder manufacturer,reset cylinder
(Italy reset cylinder,produced by Hebei Hengyu company）
reset cylinder are widely used in Italy，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed reset cylinder for customers from Italy.
When the hydraulic oil is not pumped into the reset cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the reset cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.
If the seal of the reset cylinder is abnormal wear, you can check whether the speed control valve is improperly adjusted, resulting in too high back pressure and improper installation of the seal or hydraulic oil contamination. The second is whether there is a foreign body entering the assembly and the quality of the sealing material is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and reset cylinder, and the phenomenon of "pulling the reset cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operation and improvement should be done according to the installation instructions.
reset cylinder piston rod material introduction: In general, we use 45 steel to produce reset 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.
The advantages and disadvantages of the reset cylinder: the surface of the reset cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the reset cylinder through the top heat treatment, high manufacturing precision, belongs to the precision machinery, has a simple structure, stable quality, high mechanical efficiency, easy to achieve automation and many other advantages. However, hydraulic technology also has the shortcomings of oil leakage, oil temperature change affecting the control of running speed, noise, expensive cost and high maintenance cost.
How to calculate the cylinder diameter, rod diameter and pressure of the cylinder, and how to output tonnage?
Hydraulic cylinder output force F=PAX10^3(KN) F is the output force (KN), P working pressure (MPa), A is the piston or plunger area of action.
What is st represented in the cylinder formula?
St is the original unit of kinematic viscosity, the abbreviation of Stokes, that is, Stokes, short for S. cm2/s has now been used. 1 s (St) = 10^-4m2/s.
