Paraguay hydraulic cylinder,hydraulic steering cylinder manufacturer,hydraulic steering cylinder(Paraguay hydraulic steering cylinder,produced by Hengyu Group)
hydraulic steering cylinder are widely used in Paraguay,because of clever hydraulic energy conversion,simple structure and reliable operation,excellent temperature resistance.So our company has designed hydraulic steering cylinder for customers from Paraguay.
hydraulic steering cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the hydraulic steering cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the hydraulic steering cylinder. c. The hydraulic steering cylinder seal is extruded, if the O-ring is obviously extruded at the hydraulic steering cylinder seal, replace the hydraulic steering cylinder seal.
We can not just consider the price and ignore the quality when we purchase the hydraulic steering cylinders. Now some manufacturers produce unqualified products in order to reduce costs, the piston rod is not adjusted, the rod coating is not enough, the hydraulic steering cylinder finish can not reach, the guide sleeve should use copper, but instead of ductile iron, although the cost is reduced, the quality of the hydraulic steering cylinder is not required.
How to repair the hydraulic steering cylinder body when it is damaged: When the hydraulic steering cylinder has trace deformation and shallow tensile marks, the hydraulic steering cylinder is repaired by strong honing process. The heavy honing process can repair hydraulic steering cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the hydraulic steering cylinder can meet the technical requirements.
When installing the hydraulic steering cylinder pipe, the pipe should be cleaned after installation, and should not pass through the hydraulic steering cylinder block, and the by-pass pipe must be installed in front of the oil port of the hydraulic steering cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the hydraulic steering cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the hydraulic steering 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.
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.
How big is a 300-ton cylinder piston?
The rated pressure of the oil pump is 31.5 mpa, the nominal pressure of the hydraulic press is 3150 kN, then the calculated cross-sectional area of the cylinder: S=3150000/31500000=0.1 square meters diameter is: 2* root sign (0.1/3.14) =2*0.178 m =0.356 m 3150 kN hydraulic press is commonly equipped with 31.5 mpa 63 l/min axial piston pump. There are many variable forms of axial piston pump, and the motor size of the pump with the same flow and pressure is not uniform. 31.5 mpa 63 L/min automatic variable pump, can be equipped with 15 kW 4 stage motor; The manual variable pump needs to be equipped with 22 kW 4-stage motor.
