(El Salvador plating press hydraulic cylinder,produced by Hengyu Group）

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

Introduction to plating press hydraulic cylinder:

When the plating press hydraulic cylinder is repaired, its inner and outer diameter and roundness should be accurately measured. If the inner hole of the plating press hydraulic cylinder is badly worn, it can be repaired by grinding the mandrel or honing on the boring machine. If the piston is worn, it can be repaired by electroplating, and serious wear should be replaced.

If the seal of the plating press hydraulic 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 plating press hydraulic cylinder, and the phenomenon of "pulling the plating press hydraulic 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.

In the hydraulic system, sometimes the inner layer of the rubber hose is peeled off, so that the oil circuit is on and off, resulting in irregular plating press hydraulic cylinder action. Troubleshooting method: Replace the rubber hose.

Classification of plating press hydraulic 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.

Answers to some questions about plating press hydraulic cylinder:

How to calculate the speed of cylinder weight decline?
To reduce the weight of the cylinder, the necessary condition is that the weight of the piston rod + external load is greater than the friction between the seal ring and the cylinder. There are many reasons for this, first of all, consider the reasons of the cylinder itself, the piston in the cylinder and the sealing ring on the piston rod will play a reaction force on the weight of the cylinder (because of friction), which depends on the tightness of the sealing ring and the cylinder. Secondly, what is connected under the piston rod of the cylinder and how much weight there is. And the way the cylinders are arranged, is it completely vertical. Anyway, in fact, the most important thing is to see how much the bore of the oil hole of the piston rod cavity of your cylinder is. For example, if the hole in the lower chamber of the cylinder is small, as thin as a needle, then its descent rate will be slow.

Why is there noise in the hydraulic cylinder of the excavator lift arm?
There is no noise of a normal cylinder, check whether the throttle is ringing, or the mechanical part connected with it is ringing, and the mechanical part can be greased. If it can't be ruled out, disconnect the cylinder from the mechanical part and act alone to see what the situation is.
