Republic of Lithuania hydraulic cylinder,track steering cylinder manufacturer,track steering cylinder(Republic of Lithuania track steering cylinder,produced by Hengyu Hydraulic Cylinder Factory)
track steering cylinder are widely used in Republic of Lithuania,because of no need for deceleration device,long service life,smooth movement.So our company has designed track steering cylinder for customers from Republic of Lithuania.
The method of sleeve track steering cylinder to improve the processing quality: there is a big gap in the service life of post-plating polishing and post-plating polishing, especially in mass production. Strictly clean the flying edge and burr of mechanical components, especially the edge of the sealing groove, and the tiny metal burr, strictly clean before assembly. The surface fatigue strength and stress corrosion resistance of the track steering cylinder can be significantly improved by rolling in the finishing of the inner holes of the track steering cylinder. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.
The advantages and disadvantages of the track steering cylinder: the surface of the track steering cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the track steering 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 the track steering cylinder is in use, once the seal and guide support ring are found to be defective, the seal with the same structural form and appropriate material should be replaced according to the structural form of the track steering cylinder seal to be repaired, so as to minimize the thickness of the oil film between the seal and the sealing surface and reduce the leakage of the seal.
track steering cylinder piston rod material selection and technical requirements: (I), because there is no special requirements, so use 45 steel as the piston rod material, the design of the piston rod only withstand pressure stress, so no modulation processing; (ii) The coaxial tolerance of the shaft journal and the outer circle of the mounting piston is not greater than 0.01mm, so as to ensure the coaxial degree of the outer circle of the piston rod and the outer circle of the piston, and avoid the stuck phenomenon of the piston and the track steering cylinder, the piston rod and the guide. The vertical tolerance between the end face of the mounting piston and the axis of the piston rod is not more than 0.04mm/100mm to ensure that the piston installation does not produce skew; (iii) The outer circle of the piston rod should pay attention to the roughness; (iv) Because it is operated under low load conditions, surface treatment is omitted.
Why manual forklift oil cylinder can not lift up?
Manual hydraulic forklift truck often can not be pressed up, there are several reasons: for manual hydraulic truck: 1) There is no hydraulic oil 2) the purity of the oil is not enough 3) the adjusting bolt is too close or the adjusting screw is too tight, so that the valve is always open, 4) there is an air in the hydraulic cylinder. Method: 1) Refueling 2) Oil change 3) air discharge. For manual hydraulic stacker, also called manual lift car 1) Less than the amount of oil 2) impurities in the hydraulic oil, so that the check valve can not be closed. Method 1) Add enough hydraulic oil 2) Remove the cylinder, screw off the bottom plate, remove the impurities in the bottom plate.
How to distinguish loader boom and forearm hydraulic cylinder? Is it the upper arm or the lower arm?
The one in the middle that can flip the bucket is the small arm cylinder you say, and the one that lifts the brackets (big arms) on both sides is the big arm cylinder.
