Belarus trunnion cylinder

(Belarus trunnion cylinder,produced by Hengyu Hydraulic Cylinder Factory)

trunnion cylinder are widely used in Belarus,because of smooth movement,high work efficiency,excellent fatigue and impact resistance.So our company has designed trunnion cylinder for customers from Belarus.

Introduction to trunnion cylinder:

The viscosity of the working oil used in the trunnion cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.

When the initial action of the trunnion cylinder is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the trunnion cylinder. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.

trunnion cylinder buffer valve inspection and maintenance: For the valve buffer trunnion cylinder, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.

The trunnion cylinder should be vented: when the trunnion cylinder is installed or parked for a long time to work again, the air will penetrate into the trunnion cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the trunnion cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the trunnion cylinder, the oil is best entered and discharged from the highest point of the trunnion cylinder. trunnion cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

Answers to some questions about trunnion cylinder:

What is a variable amplitude cylinder?
The type of variable amplitude cylinder is: double acting piston type cylinder, single acting plunger type cylinder, double acting two-stage telescopic cylinder. Double acting piston cylinder is the most common application. The oil cylinder has two oil outlets, and when the oil is fed into the A port, the oil is returned to the B port; If the oil inlet of the B port is returned to the oil of the A port, the reciprocating movement of the piston depends on the effect of pressure. Single-acting plunger (or piston) cylinder has only one oil port, the pressure oil can only supply oil to one side of the plunger in the cylinder, the plunger moves in one direction under the action of pressure oil, and the return stroke of the plunger is driven by the gravity of the lifting arm, such as the LT1040 truck crane variable amplitude cylinder. The double-acting two-stage telescopic cylinder is a set structure, and the two-stage piston rod is like a tie rod antenna set in the cylinder barrel.

Are hydraulic cylinders divided into oil cylinders and water cylinders? What's the difference between the two types?
There are oil cylinders and water cylinders. The two cylinders are used in different environments. Oil cylinders are generally used in places where there is less demand for media, which is our most common hydraulic cylinders. Water cylinders are mainly used for large tonnage presses. Because the equipment is too large, the use of hydraulic oil will cause a relatively large waste. However, water is not pure water, there are oil-in-water emulsion and water-in-oil emulsion. Water has another benefit: it's flame retardant. It is especially suitable for some flammable and explosive occasions. Or with water glycol. The use of pure water is very little, mainly because the seal is not good and easy to rust.
