Italy trunnion cylinder

(Italy trunnion cylinder,produced by Hebei Hengyu company)

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

Introduction to trunnion cylinder:

trunnion cylinder diameter, rod diameter, stroke determination: Choose national standards or other standards trunnion cylinder, avoid the selection of non-standard size, otherwise the difficulty of processing and manufacturing costs will be increased. The length of the trunnion cylinder guide is determined by the length of the stroke. Check the strength of trunnion cylinder, piston rod, screw, etc. according to the working pressure or load. At the same time, working pressure, ambient temperature, working medium and running speed are also the key to selecting seals.

The machining accuracy of the trunnion cylinder depends on the level of equipment, production technology and testing means. trunnion cylinder processing methods are commonly used in two ways, one is rough boring - fine boring - rolling, generally with 45# seamless steel pipe, this method of processing quality is good, but the cost is high. Another method is to use 20# cold-drawn seamless steel pipe, and then honing, the cost is lower. The piston rod must be adjusted and straightened before processing, and the coating thickness of the piston rod is generally not less than 0.03mm. The piston must be machined in strict accordance with the groove size and tolerance requirements given in the seal manual.

Factors that should be considered when selecting the oil seal in the trunnion cylinder: some specific factors should be taken into account when selecting the oil seal in the trunnion cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: trunnion cylinder diameter, piston rod diameter, piston rod and piston groove size, trunnion cylinder working pressure, trunnion cylinder movement speed, hydraulic system oil temperature and trunnion cylinder working environment.

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.

Answers to some questions about trunnion cylinder:

How to limit cylinder push rod rotation?
In general, the push-rod rotation can be limited after the push-rod is connected to the pushed mechanism. For example, the push rod is hinged with the push mechanism, or the push mechanism itself is guided, which can limit the rotation of the push rod.

Can one hydraulic pump with two cylinders work?
A hydraulic pump with two cylinders will work. Commonly used hydraulic pump types: 1, according to whether the flow can be adjusted can be divided into: variable pump and quantitative pump. The output flow can be adjusted according to the needs of the variable pump, the flow can not be adjusted called quantitative pump. 2, according to the pump structure commonly used in the hydraulic system is divided into: gear pump, vane pump and plunger pump 3 kinds. Gear pump: small volume, simple structure, the cleanliness of the oil requirements are not strict, the price is cheaper; However, the pump shaft is subjected to unbalanced force, serious wear and leakage. Vane pump: divided into double acting vane pump and single acting vane pump. The pump has uniform flow, smooth operation, low noise, higher pressure and volumetric efficiency than gear pump, and more complex structure than gear pump.
