S.Africa unidirectional cylinder

(S.Africa unidirectional cylinder,produced by Hengyu Hydraulic Co., Ltd)

unidirectional cylinder are widely used in S.Africa,because of long service life,smooth movement,high work efficiency.So our company has designed unidirectional cylinder for customers from S.Africa.

Introduction to unidirectional cylinder:

The unidirectional cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure unidirectional cylinder can use 20 steel pipe, and the high pressure unidirectional cylinder can use 45 steel pipe.

When the unidirectional 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 unidirectional cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the unidirectional cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the unidirectional cylinder can meet the requirements by grinding. However, the life and reliability of this repair unidirectional cylinder are not high.

unidirectional 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.

unidirectional cylinder can not drive the load troubleshooting: oil pressure is too low. unidirectional cylinder selection specifications are too small. Leakage in unidirectional cylinder or associated hydraulic system element.

Answers to some questions about unidirectional cylinder:

How big is a 300-ton cylinder piston?
The rated pressure of the oil pump is 31.5 mpa, the nominal pressure of the hydraulic press is 3150 kN, then the calculated cross-sectional area of the cylinder: S=3150000/31500000=0.1 square meters diameter is: 2* root sign (0.1/3.14) =2*0.178 m =0.356 m 3150 kN hydraulic press is commonly equipped with 31.5 mpa 63 l/min axial piston pump. There are many variable forms of axial piston pump, and the motor size of the pump with the same flow and pressure is not uniform. 31.5 mpa 63 L/min automatic variable pump, can be equipped with 15 kW 4 stage motor; The manual variable pump needs to be equipped with 22 kW 4-stage motor.

What are the main dimensions of the cylinder?
The main dimensions of the cylinder include: cylinder inner diameter, piston cylinder diameter, cylinder length, cylinder wall thickness, stroke, installation distance, etc.
