(Libya trunnion cylinder,produced by Hengyu Group）

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

Introduction to trunnion cylinder:

When purchasing the trunnion cylinder, try to clarify the following parameters of the trunnion cylinder: A. trunnion cylinder diameter, rod diameter, stroke; B. Working pressure or trunnion cylinder load; C. Working environment temperature; D. Working medium; E. Operating speed; F. Other parameters, such as connection form, mounting size, etc. In this way, the right trunnion cylinder type can be found accurately and quickly.

When the piston speed of the trunnion cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the trunnion cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.

When installing the piston rod, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the trunnion cylinder head adn the earring (or the middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent the phenomenon of rigid interference and causing unnecessary damage.

trunnion cylinder to reasonable use of hydraulic oil: strict hydraulic oil selection off. Hydraulic oil is selected in strict accordance with oil standards. The selection of good quality hydraulic oil can effectively prevent bubbles in the working process of the hydraulic system. When choosing the oil, it should be selected according to the lowest temperature in different regions, and fill the hydraulic oil according to the dipstick standard, and at the same time, it should also keep the hydraulic system clean (when filling the hydraulic oil, it should prevent the water and other impurities into it), and often check the oil quality, oil level and oil color of the hydraulic oil. If blisters and bubbles are found in the hydraulic oil. When the oil becomes milky white, the source of the air in the oil should be carefully found and eliminated in time.

Answers to some questions about trunnion cylinder:

How to calculate cylinder speed?
If there is a throttle valve, the cylinder speed will be adjustable. When the throttle is fully opened, the speed of the cylinder reaches the maximum: maximum speed = oil pump displacement ÷ cylinder cavity cross-sectional area The displacement of the oil pump is a main indicator, which can be found on the nameplate, and some can also be known by the oil pump model; The cross-sectional area of the cylinder cavity can be easily calculated. Just make sure the units are the same. And because the cross-sectional area of the rod cavity and the rodless cavity of the cylinder is different, the speed of advance and retreat may also be different.

To achieve the same stroke, which is better, hydraulic cylinder or lead screw?
If there is batch action, then the hydraulic pressure is better. Hydraulic: smooth operation, no lubrication, easy control, high control accuracy (can use proportional or servo system), the key is to manually control, but certainly to support the hydraulic system, for a single action must cost. Maintenance costs are also high. Lead screw: simple structure, easy to achieve, convenient maintenance, but must be lubricated, can not be manual, or manual control is inconvenient. See where it is used, if it is used in high-precision occasions, it must only be hydraulic, because the lead screw has a gap. There are many hydraulic actions, the hydraulic system itself must be prepared, then the use of hydraulic pressure is also very economical.
