Pakistan hydraulic cylinder,stern plate hydraulic cylinder manufacturer,stern plate hydraulic cylinder(Pakistan stern plate hydraulic cylinder,produced by Hebei Hengyu company)
stern plate hydraulic cylinder are widely used in Pakistan,because of no transmission clearance,powerful torque,clever hydraulic energy conversion.So our company has designed stern plate hydraulic cylinder for customers from Pakistan.
The machining accuracy of the stern plate hydraulic cylinder depends on the level of equipment, production technology and testing means. stern plate hydraulic cylinder processing methods are commonly used in two ways, one is rough boring - fine boring - rolling, generally with 45# seamless steel pipe, this method of processing quality is good, but the cost is high. Another method is to use 20# cold-drawn seamless steel pipe, and then honing, the cost is lower. The piston rod must be adjusted and straightened before processing, and the coating thickness of the piston rod is generally not less than 0.03mm. The piston must be machined in strict accordance with the groove size and tolerance requirements given in the seal manual.
The internal leakage of the stern plate hydraulic cylinder is an important indicator to measure the quality of the stern plate hydraulic cylinder: the internal leakage of the stern plate hydraulic cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the stern plate hydraulic cylinder, so that the stern plate hydraulic cylinder can not accurately and stably stop in a certain position of the stern plate hydraulic cylinder, so it is one of the main indicators of the stern plate hydraulic cylinder.
stern plate hydraulic cylinder diameter, rod diameter, stroke determination: Choose national standards or other standards stern plate hydraulic cylinder, avoid the selection of non-standard size, otherwise the difficulty of processing and manufacturing costs will be increased. The length of the stern plate hydraulic cylinder guide is determined by the length of the stroke. Check the strength of stern plate hydraulic 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.
When installing the stern plate hydraulic cylinder pipe, the pipe should be cleaned after installation, and should not pass through the stern plate hydraulic cylinder block, and the by-pass pipe must be installed in front of the oil port of the stern plate hydraulic cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the stern plate hydraulic cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the stern plate hydraulic 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.
Why hydraulic cylinder load can not rise?
The hydraulic cylinder does not top up indicates that the pressure of the working chamber of the hydraulic cylinder is insufficient, and the following circumstances can lead to insufficient pressure: 1) The relief valve of the hydraulic system cannot establish pressure, elimination method: check whether the pressure setting screw of the relief valve is screwed to the appropriate position. If it is an electromagnetic relief valve, please check the power-on condition. 2) The hydraulic system pipeline is connected incorrectly, when P and T are connected, this must be checked and excluded; 3) Excessive leakage in the hydraulic cylinder, resulting in (only for double-acting cylinders); 3) No hydraulic oil into the working chamber of the hydraulic cylinder, elimination method: first disassemble the hydraulic pipe connecting the reversing valve and the hydraulic cylinder, and then control the reversing valve, and observe whether there is hydraulic oil flowing out of the reversing valve.
What is a two-way hydraulic cylinder?
Bidirectional hydraulic cylinder definition: The bidirectional hydraulic cylinder uses the oil as the working medium, transmits the movement through the change of the sealing volume, and transmits the power through the pressure inside the oil. The two-way cylinder has at least two oil ports, which are used to connect the hydraulic tubing, and control the extension and retraction of the cylinder by pressing.
