Tanzania hydraulic cylinder,vehicle hydraulic cylinder manufacturer,vehicle hydraulic cylinder(Tanzania vehicle hydraulic cylinder,produced by Hengyu Group)
vehicle hydraulic cylinder are widely used in Tanzania,because of powerful torque,clever hydraulic energy conversion,simple structure and reliable operation.So our company has designed vehicle hydraulic cylinder for customers from Tanzania.
At the rated pressure, the thrust of the vehicle hydraulic cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the vehicle hydraulic cylinder is related to the diameter of the vehicle hydraulic cylinder, but not to the stroke of the vehicle hydraulic cylinder. Moreover, the larger the vehicle hydraulic 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 vehicle hydraulic cylinder.
vehicle hydraulic cylinder hydraulic oil selection: The recommended working oil viscosity of the vehicle hydraulic cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.
vehicle hydraulic cylinders in series, parallel and series parallel. Series: In the vehicle hydraulic cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Series: In the vehicle hydraulic cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Parallel: the pressure oil in the vehicle hydraulic cylinder is connected with the inlet oil of each reversing valve, and the return oil is collected by the return oil circuit. Series parallel: For this one, compared with the simple series and parallel, it is slightly more complicated, but it is not impossible to understand. The series refers to the oil in the vehicle hydraulic cylinder, which is in series form, but can not form a series circuit, and the parallel refers to the oil return circuit of each valve, which is in parallel.
When installing the vehicle hydraulic cylinder pipe, the pipe should be cleaned after installation, and should not pass through the vehicle hydraulic cylinder block, and the by-pass pipe must be installed in front of the oil port of the vehicle hydraulic cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the vehicle hydraulic cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the vehicle hydraulic cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.
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.
Can a leak in the cylinder cause the hydraulic system to fail?
Leakage in the cylinder can cause the hydraulic system to fail. Cylinder leakage (internal leakage) first affects the controlled action of the hydraulic system can not meet the requirements (such as the movement speed of the cylinder, the insufficient thrust and tension of the cylinder), if the internal leakage of the cylinder is too large, it may also cause the cylinder to be unable to promote the load movement. Second, the existence of internal leakage (internal leakage) of the oil cylinder will lead to the rapid rise (or too high) of the oil temperature of the hydraulic system, and the high oil temperature will not only waste the energy conversion of the system, but also lead to the reduction of the viscosity of the oil, which will accelerate the aging and destruction of the seals such as pumps, valves, cylinders, pipelines, and at the same time, the lubrication effect of the hydraulic oil is reduced, and the production of iron filings that increase the friction of the hydraulic system.
