(Costa Rica tailplate hydraulic cylinder,produced by Hebei Hengyu company）

tailplate hydraulic cylinder are widely used in Costa Rica，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed tailplate hydraulic cylinder for customers from Costa Rica.

Introduction to tailplate hydraulic cylinder:

There are some honeycomb holes in the inner wall of the tailplate hydraulic cylinder, piston or piston rod surface. How is this formed? When we repair the tailplate hydraulic cylinder, we can see that there are some honeycomb holes on the inner wall of the tailplate hydraulic cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the tailplate hydraulic cylinder is targeted to prevent. Is very necessary.

tailplate hydraulic cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the tailplate hydraulic cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the tailplate hydraulic cylinder. c. The tailplate hydraulic cylinder seal is extruded, if the O-ring is obviously extruded at the tailplate hydraulic cylinder seal, replace the tailplate hydraulic cylinder seal.

If the tailplate hydraulic cylinder piston rod is found to be worn, it can be brushed and plated first, then ground, and finally adjust the mating accuracy of the piston rod and the guide sleeve. At this time, the guide sleeve can be properly redrilled or the guide sleeve can be re-turned. When making the above repairs, remember to replace various rubber seals in time.

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

Answers to some questions about tailplate hydraulic cylinder:

How to choose cylinder size, pump type, motor power for a 30-ton press?
30 tons = 30,000 kg. It is expected to use a 16 mpa oil pump, then the cylinder area =30000/(160x3.14) and then square, the cylinder bore is 150 mm. Calculated at 500 mm travel per minute, the flow rate per minute is :0.75^2x3.14x5=8.8 liters/minute. Motor power =8.8x16/60=2.355. A 9 L/min, 16 mpa pump is available. Piston diameter 150 mm cylinder. 3 kW motor.

How to store hydraulic cylinder?
After cleaning the hydraulic cylinder with diesel or kerosene, apply lubricating oil and wrap it in oil paper, preferably in a wooden box, and store it in a dry and non-corrosive environment. The outer surface and inner surface of the hydraulic cylinder are sprayed with diesel oil, and the inner layer is covered with cloth and the outer coating of anti-rust oil is good. Put it in a dry place, clean it with diesel oil, and then apply a layer of anti-rust inside and outside the butter.
