Norway hydraulic cylinder,tension cylinder manufacturer,tension cylinder
(Norway tension cylinder,produced by Hengyu Hydraulic Co., Ltd）
tension cylinder are widely used in Norway，because of no need for deceleration device，long service life，smooth movement.So our company has designed tension cylinder for customers from Norway.
The material of the sliding part of the tension cylinder piston sintered casting piston will cause sintering phenomenon when subjected to large transverse load. In this case, the sliding part of the piston should be made of copper alloy or welded to such material.
When the tension cylinder wear is serious, you can try to use an alloy scraper to shave grooves with a depth of more than 1mm on the surface of the slip injury, then clean the grooves with acetone, apply the adjusted TS311 anti-wear repair agent on the polished surface with the tension cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the tension cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the tension cylinder can meet the requirements by grinding. However, the life and reliability of this repair tension cylinder are not high.
tension cylinder piston sealing is best to use Yx ring, polyurethane and polytetrafluoroethylene sealing material combination, can significantly improve the sealing performance: (I), reduce friction resistance, no crawling phenomenon; (ii) Have good dynamic and static sealing, wear resistance, long service life; (iii) The installation groove is simple, and the disassembly is simple.
tension cylinder body inspection: The inner surface of the tension cylinder and the piston seal are the main factors causing the leakage in the tension cylinder, if the tension cylinder has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the tension cylinder mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.
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 does cylinder speed ratio mean?
The speed ratio of the cylinder is the ratio of the reciprocating speed of the piston, equal to the ratio of the rodless cavity area to the roded cavity area.
