Tunisia hydraulic cylinder,non-standard special type cylinder manufacturer,non-standard special type cylinder(Tunisia non-standard special type cylinder,produced by Hengyu Hydraulic Co., Ltd)
non-standard special type cylinder are widely used in Tunisia,because of simple structure and reliable operation,excellent temperature resistance,no transmission clearance.So our company has designed non-standard special type cylinder for customers from Tunisia.
When installing the non-standard special type cylinder pipe, the pipe should be cleaned after installation, and should not pass through the non-standard special type cylinder block, and the by-pass pipe must be installed in front of the oil port of the non-standard special type cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the non-standard special type cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the non-standard special type 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.
The advantages and disadvantages of the non-standard special type cylinder: the surface of the non-standard special type cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the non-standard special type 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.
non-standard special type cylinder diameter, rod diameter, stroke determination: Choose national standards or other standards non-standard special type cylinder, avoid the selection of non-standard size, otherwise the difficulty of processing and manufacturing costs will be increased. The length of the non-standard special type cylinder guide is determined by the length of the stroke. Check the strength of non-standard special type cylinder, piston rod, screw, etc. according to the working pressure or load. At the same time, working pressure, ambient temperature, working medium and running speed are also the key to selecting seals.
How the cavitation of the non-standard special type cylinder is formed: With the gradual rise of pressure, the gas in the oil will become bubbles, when the pressure rises to a certain limit value, these bubbles will break under the action of high pressure, so that the high temperature and high pressure gas will quickly act on the surface of the parts, resulting in cavitation of the non-standard special type cylinder, resulting in corrosive damage to the parts.
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.
What is the main maintenance of the cylinder?
After disassembling the cylinder: 1, clean the cylinder and piston; 2, replace all seals; 3, if there is a valve to repair, to ensure sealing and flexible; 4, deal with all deformation parts; 5. Installation experiment.
