trunnion cylinder are widely used in Holland,because of no transmission clearance,powerful torque,clever hydraulic energy conversion.So our company has designed trunnion cylinder for customers from Holland.

Introduction to trunnion cylinder:

In the process of using the trunnion cylinder, sometimes such a problem will occur, the trunnion cylinder can not act immediately after the instruction of the trunnion cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil trunnion cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

If the piston rod and trunnion cylinder are stuck or the trunnion cylinder is blocked, at this time, no matter how to operate, the trunnion 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 trunnion cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

At the rated pressure, the thrust of the trunnion cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the trunnion cylinder is related to the diameter of the trunnion cylinder, but not to the stroke of the trunnion cylinder. Moreover, the larger the trunnion cylinder diameter, the larger the area, and the greater the pressure obtained. To this point, we should have a correct understanding and clear understanding, so as to avoid problems in the use of the trunnion cylinder.

How the cavitation of the trunnion cylinder is formed: With the gradual rise of pressure, the gas in the oil will become bubbles, when the pressure rises to a certain limit value, these bubbles will break under the action of high pressure, so that the high temperature and high pressure gas will quickly act on the surface of the parts, resulting in cavitation of the trunnion cylinder, resulting in corrosive damage to the parts.

Answers to some questions about trunnion cylinder:

Is rubber or polyurethane better for V-ring of hydraulic cylinder?
The hydraulic cylinder V-type seal ring is better with polyurethane, and chlorine rubber is used for various chemicals and high temperatures, especially when there are wear-resistant requirements, polyurethane rubber is needed. But the price of polyurethane rubber is much more expensive than the price of rubber. However, the V-ring material is most commonly used in nitrile and neoprene rubber, and natural rubber is used for sealing water and air. Butyl rubber is used for non-combustible hydraulic fluids and phosphate ester hydraulic fluids. The advantage is that the price is cheaper than the polyurethane material, and the disadvantage is that it is not wear-resistant and the anti-aging property is relatively poor.

Need a hydraulic cylinder, vertical upward 10 seconds to lift 20 tons of weight up 2 meters, how large cylinder and rod, how much pressure to use the plunger pump and how big?
The first thing to determine the system pressure, let's say 25 mpa, can take into account cost and performance. 1 Cylinder area 20000/250=80 square cm cylinder diameter (80/3.14) squared x2=200 mm 2 cylinder volume 80x200=16000 ml =16 L 3 Required pump flow 16x60/10=96 L/min 4 Power 96x25/55=43 kW 45 kW motor is available.
