(Greece trunnion cylinder,produced by Hengyu Group）

trunnion cylinder are widely used in Greece，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed trunnion cylinder for customers from Greece.

Introduction to trunnion cylinder:

Regular maintenance of the trunnion cylinder includes: regular tightening, trunnion cylinder fastening screws and gland screws, trunnion cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the trunnion cylinder once a year. Clean regularly, the trunnion cylinder is cleaned every other year, and the seals are replaced while cleaning.

The main role of the trunnion cylinder: the trunnion cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the trunnion cylinder realizes reciprocating motion. The structure of the trunnion cylinder has three categories: piston trunnion cylinder, plunger trunnion cylinder, swing trunnion cylinder, piston trunnion cylinder and plunger trunnion cylinder to achieve reciprocating linear motion, output speed and thrust, swing trunnion cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the trunnion cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The trunnion cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.

The trunnion cylinder pipe should not be left behind when deburring at both ends after the fixed length processing. In addition, the placement of steel pipes near the site of welding pipeline operations is the cause of welding foreign objects. The pipes placed near the welding operation site should be sealed. It must also be noted that pipe fitting materials should be fully prepared on a dust-free workbench.

If air enters the hydraulic system, the trunnion cylinder will not operate normally, mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced.

Answers to some questions about trunnion cylinder:

How many boom cylinders, bucket rod cylinders and bucket cylinders are there in a small single-bucket excavator?
one for bucket, one for forearm, only one piece for a small excavator under the big arm, two pieces for medium and large excavator.

Why does the hydraulic cylinder ring?
1 Air intrusion into the hydraulic system is the main reason for noise 2 The relief valve is unstable, such as due to the improper combination of the slide valve and the valve hole or the contact of the cone valve and the seat is stuck by dirt, the damping hole is blocked, the spring is crooked or fails to make the spool stuck or move in the valve hole, causing system pressure fluctuation and noise. 3 Improper adjustment of the reversing valve causes the spool of the reversing valve to move too fast, resulting in reversing impact, resulting in noise and vibration. 4 Mechanical vibration, such as long tubing, elbow more and not fixed, when the oil flow through, especially when the flow rate is high, easy to cause pipe shaking; The rotating part of the motor and hydraulic pump is unbalanced, or the alignment is not good during installation, or the coupling is loose, etc., which can produce vibration and noise.
