(Denmark trunnion cylinder,produced by Hengyu Hydraulic Cylinder Factory）

trunnion cylinder are widely used in Denmark，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed trunnion cylinder for customers from Denmark.

Introduction to trunnion cylinder:

Repair method of small range wear of oil trunnion cylinder: 1. Use oxygen-acetylene flame to bake the scratched part (master the temperature, avoid surface annealing), bake the oil on the metal surface all the year round until no sparks splash; 2. The scratched part is treated with an Angle grinder, the grinding depth is more than 1 mm, and the groove is polished along the guide rail, preferably a dovetail groove. Scratch both ends of the drilling deeper, change the force situation; 3. Clean the surface with absorbent cotton dipped in acetone or anhydrous ethanol.

Piston trunnion cylinder is widely used in hydraulic transmission. When the trunnion cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the trunnion cylinder, and uses the pressure difference of hydraulic oil on both sides of the piston to realize the reciprocating movement of the piston. If you want to speed up the forward speed of the piston, the return oil in the trunnion cylinder can be controlled by the valve and directly input into the inlet pipe to participate in the work of the piston to achieve rapid movement of the piston, but the thrust of the piston is reduced much.

When the trunnion 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 trunnion cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the trunnion cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the trunnion cylinder can meet the requirements by grinding. However, the life and reliability of this repair trunnion cylinder are not high.

The repair method of the trunnion cylinder: the repair of the trunnion cylinder must use brush plating. This is because this repair method can be carried out on site, and the repair effect is good. In this way, loading and transportation can be eliminated to shorten the repair time and improve work efficiency. In addition, the coating obtained by brush plating has good binding force and will not have obvious boundaries. Moreover, the repair surface has high hardness and good wear resistance.

Answers to some questions about trunnion cylinder:

What brand of hydraulic cylinder seal ring is best?
Depending on the specific product, the world famous seal brands are NOK, CFW, PARKER, TSS, WKF, DINGZING DZ, ASTON, HALLITE, TECNOLAN and so on.

Why does the cylinder pop out of itself when it stops?
This situation has two possibilities, 1. There is more air in the system, so exhaust the gas. 2. The back pressure of the oil return is relatively large, check the oil return filter, check whether the cylinder has a rod cavity buffer is too tight, and choose a 3-position 4-way M-type valve for the reversing valve. In addition, after the shutdown, manually change the reversing valve back and forth several times, it should not rise out.
