press hydraulic cylinder Sold to Romania

This article mainly introduces:

Romania hydraulic cylinder,press hydraulic cylinder manufacturer,press hydraulic cylinder

(Romania press hydraulic cylinder,produced by Hebei Hengyu company）

press hydraulic cylinder are widely used in Romania，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed press hydraulic cylinder for customers from Romania.

Introduction to press hydraulic cylinder:

The wear of the hard chromium plating layer of the press hydraulic cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.

In order to ensure the service life of the press hydraulic cylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the press hydraulic cylinder, causing damage to the seal and causing leakage in the press hydraulic cylinder. It is required that the filtration accuracy of the system is not less than 80μm, the oil pollution is strictly controlled, the hydraulic oil is kept clean, the performance of the hydraulic oil is regularly checked, and the necessary fine filtration or replacement of the new working hydraulic oil is carried out.

When installing the press hydraulic cylinder, the axial ends of the press hydraulic cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the press hydraulic cylinder, there is axial expansion. If the two ends of the press hydraulic cylinder are fixed, all parts of the press hydraulic cylinder will be deformed. When disassembling the press hydraulic cylinder, it is strictly forbidden to hammer the press hydraulic cylinder and the piston surface, such as the press hydraulic cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.

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

Answers to some questions about press hydraulic cylinder:

What is the cause of sound and vibration when the hydraulic cylinder is under load?
The main reason 1) may be that the load machinery has stuck phenomenon, and the resistance is large. 2) The hydraulic oil is not enough, or the filter is blocked by dirty things, and the oil is flooded. 3) There is a problem with the pump.

CNC lathe rotary cylinder oil leakage and treatment methods
Oil leakage often occurs when the cylinder (especially the hollow cylinder) of the CNC lathe is installed. First check the cylinder yaw, be sure to reach or close to the required value, generally the cylinder requires the outer beat within 1 wire. Otherwise, too much beating is sure to leak oil. Then check whether the tubing is smoothly downward at a certain Angle, and can not bend. Look at the pipe outlet can not go into the oil level, to a little higher. Otherwise, there's back pressure and it's gonna leak.
