Algeria press machine hydraulic cylinder

(Algeria press machine hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)

press machine hydraulic cylinder are widely used in Algeria,because of high work efficiency,excellent fatigue and impact resistance,no need for deceleration device.So our company has designed press machine hydraulic cylinder for customers from Algeria.

Introduction to press machine hydraulic cylinder:

When the press machine hydraulic cylinder wear is serious, you can try to use an alloy scraper to shave grooves with a depth of more than 1mm on the surface of the slip injury, then clean the grooves with acetone, apply the adjusted TS311 anti-wear repair agent on the polished surface with the press machine hydraulic cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the press machine hydraulic cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the press machine hydraulic cylinder can meet the requirements by grinding. However, the life and reliability of this repair press machine hydraulic cylinder are not high.

The wear of the hard chromium plating layer of the press machine 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.

The quality of the press machine hydraulic cylinder can not be ignored in the purchase of the press machine hydraulic cylinder. The press machine hydraulic cylinder is the main component of the press machine hydraulic cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. press machine hydraulic cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of press machine hydraulic cylinder is deep hole processing, which has always troubled the processing personnel.

If the piston rod and press machine hydraulic cylinder are stuck or the press machine hydraulic cylinder is blocked, at this time, no matter how to operate, the press machine hydraulic cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the press machine hydraulic cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

Answers to some questions about press machine hydraulic cylinder:

What is the difference between hydraulic piston cylinder and plunger cylinder?
The force surface of the piston cylinder is a rod cavity and a rodless cavity, and the force surface of the plunger cylinder is the plunger, the spring return single-acting piston cylinder can also rely on the external force of the spring to achieve return, the double-acting piston cylinder can produce tension, and the plunger cylinder only produces thrust without tension.

When the cylinder is tested, why can't the pressure be maintained with the balance valve?
Because the oil into the oil chamber through the hydraulic lock on the control oil circuit through the other side of the spool, the original valve is designed in this way. It locks the circuit after the oil supply circuit loses pressure, on the contrary, if you keep supplying pressure, it is always in the state of opening the other side of the one-way spool. So this valve can't be used in the test.
