Holland hydraulic cylinder,cylinder with sensor manufacturer,cylinder with sensor

(Holland cylinder with sensor,produced by Hengyu Hydraulic Cylinder Factory）

cylinder with sensor are widely used in Holland，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed cylinder with sensor for customers from Holland.

Introduction to cylinder with sensor:

When the cylinder with sensor needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the cylinder with sensor, and hard beating and sudden drop are strictly prohibited during disassembly.

If it is found that the cylinder with sensor lubrication is poor or the cylinder with sensor bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the cylinder with sensor, the guide rail and the piston rod have relative movement, if the lubrication is poor or the cylinder with sensor bore is abnormal, it will aggravate the wear and reduce the straightness of the cylinder with sensor center line. In this way, when the piston works in the cylinder with sensor, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the cylinder with sensor first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

The daily inspection of the cylinder with sensor includes: checking the connection of the cylinder with sensor and the pipe joint for leaks. Check the cylinder with sensor rod for leaks. Check the cylinder with sensor connection for leaks. When the cylinder with sensor moves, the work is normal and smooth. Whether the cylinder with sensor has internal leakage.

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

How to change the seal ring of lift oil cylinder of forklift truck?
Remove the cylinder, put it on the vise, first screw off the big nut plug on the head, and then pull out the guide sleeve, you can directly pull out the core of the cylinder, if it is to change the seal of the cylinder head, the core does not need to be pulled out, if it is to change the seal inside, pull it out and see the oil seal, remove it and replace it, there are three seals of the cylinder head, the inner seal, The outer seal, dustproof, it is best to replace them all together, and be sure to keep them clean when changing, and you can lubricate them with clean hydraulic oil.

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.
