Sudan hydraulic cylinder,plunger type cylinder manufacturer,plunger type cylinder

(Sudan plunger type cylinder,produced by Hebei Hengyu company）

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

Introduction to plunger type cylinder:

When the plunger type cylinder is installed on the main engine, the oil port piping part and the guide sleeve should be checked for oil leakage in the running test, and the earring and the middle hinge shaft bearing should be refueled.

plunger type 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.

Disassembly plunger type cylinder: When disassembly plunger type cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the plunger type cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the plunger type cylinder.

How to determine the working pressure of the plunger type cylinder: The pressure depends on the load size (i.e., F) and the type of equipment. The limitations of assembly space, economic conditions and component availability of the actuator should also be considered. In the case of a certain load, it is necessary to increase the structural size of the actuator if the working pressure is low, for some equipment, the size may be limited, and it is not economical from the point of view of material consumption; On the contrary, if the pressure selection is too high, the material, sealing and manufacturing accuracy of the pump, plunger type cylinder, valve and other components are also required to be high, which will inevitably increase the cost of equipment. In general, for equipment with a fixed size that is not too limited, the pressure can be selected lower, and the walking machinery should be selected higher.

Answers to some questions about plunger type cylinder:

When the cylinder is tested, why can't the pressure be maintained with the balance valve?
Because the oil into the oil chamber through the hydraulic lock on the control oil circuit through the other side of the spool, the original valve is designed in this way. It locks the circuit after the oil supply circuit loses pressure, on the contrary, if you keep supplying pressure, it is always in the state of opening the other side of the one-way spool. So this valve can't be used in the test.

What is the relationship between medium cylinder and side cylinder ratio of forklift truck?
The middle cylinder and the side cylinder seem to have no relationship, as long as the lifting speed required by the design can be ensured, but the diameter of the cylinder can not be too thin, so as to avoid the middle cylinder acting first when the high gantry vibration lifting, and then the two cylinders acting again.
