Jordan hydraulic cylinder,trunnion cylinder manufacturer,trunnion cylinder

(Jordan trunnion cylinder,produced by Hebei Hengyu company）

trunnion cylinder are widely used in Jordan，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed trunnion cylinder for customers from Jordan.

Introduction to trunnion cylinder:

trunnion cylinder spool stuck or valve hole blocked How to solve: When the flow valve or direction valve spool stuck or valve hole blocked, the trunnion cylinder prone to misoperation or action failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium.

If the seal of the trunnion cylinder is abnormal wear, you can check whether the speed control valve is improperly adjusted, resulting in too high back pressure and improper installation of the seal or hydraulic oil contamination. The second is whether there is a foreign body entering the assembly and the quality of the sealing material is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and trunnion cylinder, and the phenomenon of "pulling the trunnion cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operation and improvement should be done according to the installation instructions.

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.

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.

Answers to some questions about trunnion cylinder:

How to set the stroke of the cylinder?
Self-design should be based on product demand and practical application. The stroke of standard cylinder depends on the parameters the customer requires. The hydraulic cylinder is a linear motion actuator whose output force is proportional to the effective area of the piston and the pressure difference on both sides. Its function is to convert hydraulic energy into mechanical energy. The input of the hydraulic cylinder is the flow rate and pressure of the fluid, and the output is the speed and force of the linear motion. The piston of the hydraulic cylinder can complete the linear reciprocating movement, and the linear displacement of the output is limited. Hydraulic cylinder is an energy conversion device that converts hydraulic energy into mechanical energy of reciprocating linear motion. The hydraulic cylinder is basically composed of cylinder body, cylinder head, piston and piston rod, sealing device, buffer device and exhaust device.

What are the causes of hydraulic cylinder oil leakage?
First, between the piston rod and the guide sleeve: 1, the cylinder force is not good, there is a radial force between the piston rod and the guide sleeve there is a partial load, so that the oil seal is worn early, causing oil leakage. 2. The ambient temperature of the piston rod is high, especially radiant heat, and the oil seal aging is fast. 3. Whether the oil seal is selected correctly; Check whether the oil seal is damaged during installation. 4, guide sleeve and piston rod matching tolerance is correct. Second, between guide sleeve and cylinder: 1. Whether the O-ring on the guide sleeve is installed correctly, pay special attention to the O-ring can not "roll", especially some O-rings are die-pressed with a die-closing line. Third, common problems: 1, guide sleeve, cylinder, piston rod concentricity is poor. Fit tolerance is correct.
