hydraulic jack cylinder are widely used in Brazil,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed hydraulic jack cylinder for customers from Brazil.

Introduction to hydraulic jack cylinder:

The body of the hydraulic jack cylinder on the processing process requirements: the body of the hydraulic jack cylinder is an important and essential part of the hydraulic jack cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the hydraulic jack cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.

hydraulic jack 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.

The daily inspection of the hydraulic jack cylinder includes: checking the connection of the hydraulic jack cylinder and the pipe joint for leaks. Check the hydraulic jack cylinder rod for leaks. Check the hydraulic jack cylinder connection for leaks. When the hydraulic jack cylinder moves, the work is normal and smooth. Whether the hydraulic jack cylinder has internal leakage.

When installing the piston rod, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the hydraulic jack cylinder head adn the earring (or the middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent the phenomenon of rigid interference and causing unnecessary damage.

Answers to some questions about hydraulic jack cylinder:

When the cylinder is tested, why can't the pressure be maintained with the balance valve?
Because the oil into the oil chamber through the hydraulic lock on the control oil circuit through the other side of the spool, the original valve is designed in this way. It locks the circuit after the oil supply circuit loses pressure, on the contrary, if you keep supplying pressure, it is always in the state of opening the other side of the one-way spool. So this valve can't be used in the test.

What kind of seal ring we should choose for 120Mpa hydraulic cylinder?
The sealing rings used in mining machinery are high pressure, which can reach 150MPa. It is generally composed of three parts, the guide ring, the sealing body and the elastomer. It's not a special structure. It's more mature. Usually said mountain circle, bud circle.
