Uganda hydraulic cylinder,tailboard balance cylinder manufacturer,tailboard balance cylinder(Uganda tailboard balance cylinder,produced by Hengyu Hydraulic Cylinder Factory)
tailboard balance cylinder are widely used in Uganda,because of long service life,smooth movement,high work efficiency.So our company has designed tailboard balance cylinder for customers from Uganda.
1, the hydraulic machinery should be kept clean, in order to prevent dust and debris from falling into the oil, the tank should be sealed. 2, the oil in the tank should be replaced regularly according to the working condition. When changing the oil, the dirt and impurities accumulated at the bottom of the tank should be removed and the tank should be cleaned. 3, hydraulic oil, oil drums should be set in a clean and safe place to strengthen management. The oil drum, oil filter, oil funnel, oil pipe, etc. used should be kept clean. The oil drums for loading hydraulic oil must be cleaned in advance, and the oil drums should be dedicated and not mixed with other oil drums.
tailboard balance 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 tailboard balance cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the tailboard balance cylinder. c. The tailboard balance cylinder seal is extruded, if the O-ring is obviously extruded at the tailboard balance cylinder seal, replace the tailboard balance cylinder seal.
When installing the tailboard balance cylinder, the axial ends of the tailboard balance cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the tailboard balance cylinder, there is axial expansion. If the two ends of the tailboard balance cylinder are fixed, all parts of the tailboard balance cylinder will be deformed. When disassembling the tailboard balance cylinder, it is strictly forbidden to hammer the tailboard balance cylinder and the piston surface, such as the tailboard balance cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.
The internal leakage of the tailboard balance cylinder is an important indicator to measure the quality of the tailboard balance cylinder: the internal leakage of the tailboard balance cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the tailboard balance cylinder, so that the tailboard balance cylinder can not accurately and stably stop in a certain position of the tailboard balance cylinder, so it is one of the main indicators of the tailboard balance cylinder.
How does the variable amplitude cylinder work?
The variable amplitude cylinder is generally an engineering hydraulic cylinder connected by the front and back earrings, and the telescopic expansion of the hydraulic cylinder changes the Angle of the arm of the lifting machinery to achieve the role of the variable amplitude, according to the role it plays is called the variable amplitude cylinder, and there is no variable amplitude hydraulic cylinder in the classification of hydraulic cylinders.
What are the causes of hydraulic cylinder oil leakage?
First, between the piston rod and the guide sleeve: 1, the cylinder force is not good, there is a radial force between the piston rod and the guide sleeve there is a partial load, so that the oil seal is worn early, causing oil leakage. 2. The ambient temperature of the piston rod is high, especially radiant heat, and the oil seal aging is fast. 3. Whether the oil seal is selected correctly; Check whether the oil seal is damaged during installation. 4, guide sleeve and piston rod matching tolerance is correct. Second, between guide sleeve and cylinder: 1. Whether the O-ring on the guide sleeve is installed correctly, pay special attention to the O-ring can not "roll", especially some O-rings are die-pressed with a die-closing line. Third, common problems: 1, guide sleeve, cylinder, piston rod concentricity is poor. Fit tolerance is correct.
