Brazil hydraulic cylinder,vehicle hydraulic cylinder manufacturer,vehicle hydraulic cylinder(Brazil vehicle hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)
vehicle hydraulic cylinder are widely used in Brazil,because of no transmission clearance,simple structure and reliable operation,excellent temperature resistance.So our company has designed vehicle hydraulic cylinder for customers from Brazil.
The wear of the hard chromium plating layer of the vehicle hydraulic cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.
The advantages and disadvantages of the vehicle hydraulic cylinder: the surface of the vehicle hydraulic cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the vehicle hydraulic cylinder through the top heat treatment, high manufacturing precision, belongs to the precision machinery, has a simple structure, stable quality, high mechanical efficiency, easy to achieve automation and many other advantages. However, hydraulic technology also has the shortcomings of oil leakage, oil temperature change affecting the control of running speed, noise, expensive cost and high maintenance cost.
When using the vehicle hydraulic cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the vehicle hydraulic cylinder block. If the vehicle hydraulic cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the vehicle hydraulic cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the vehicle hydraulic cylinder, so that the working efficiency of the vehicle hydraulic cylinder is reduced.
The internal leakage of the vehicle hydraulic cylinder is an important indicator to measure the quality of the vehicle hydraulic cylinder: the internal leakage of the vehicle hydraulic cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the vehicle hydraulic cylinder, so that the vehicle hydraulic cylinder can not accurately and stably stop in a certain position of the vehicle hydraulic cylinder, so it is one of the main indicators of the vehicle hydraulic cylinder.
How to calculate the cross-sectional area of hydraulic cylinder?
Hydraulic cylinder cross section integral rod cavity and rodless cavity: rod cavity is cylinder inner wall cross-sectional area - piston rod cross-sectional area; The rodless cavity is the cross-sectional area of the inner wall of the cylinder. If the working pressure p and the output force F are known, the effective cross-sectional area A=F/p can be calculated.
Why can't the hydraulic cylinder be replaced with water?
Hydraulic oil for hydraulic transmission has a variety of requirements for viscosity, density, flow rate, and temperature, which are not available for water.
