Tanzania hydraulic cylinder,push and pull the cylinder manufacturer,push and pull the cylinder(Tanzania push and pull the cylinder,produced by Hengyu Group)
push and pull the cylinder are widely used in Tanzania,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed push and pull the cylinder for customers from Tanzania.
When the long-stroke push and pull the cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in push and pull the cylinder head seal damage, oil leakage, and piston sleep in the push and pull the cylinder. The following measures can be taken: increase the piston plan to adjust the piston outer circle and process it into a convex drum, so that the piston can self-position, improve the force situation, and reduce and avoid pulling the push and pull the cylinder; The piston and the piston rod are connected with a spherical joint.
When installing the push and pull the cylinder, the axial ends of the push and pull the cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the push and pull the cylinder, there is axial expansion. If the two ends of the push and pull the cylinder are fixed, all parts of the push and pull the cylinder will be deformed. When disassembling the push and pull the cylinder, it is strictly forbidden to hammer the push and pull the cylinder and the piston surface, such as the push and pull the cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.
push and pull the 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.
When the oil pressure of the push and pull the cylinder inlet is too low to reach the specified value, the leakage situation of the relevant oil system should be checked and the leakage should be eliminated; Check the piston and piston rod seal ring for damage, aging, loose and other phenomena; Check whether the hydraulic pump and pressure valve are faulty.
How do hydraulic equipment and hydraulic cylinders maintain a certain pressure after pressing to a certain position?
There are several methods. 1. You can use a constant pressure variable pump to adjust the control pressure of the pump to the pressure required by the cylinder, so that when the cylinder is in place, the pump uses the minimum flow rate to maintain the pressure, and the system is more energy saving. 2. If the pressure is maintained for a short time, a hydraulic control check valve can be added to the oil inlet end of the cylinder to close the cylinder and maintain the pressure. If the volume of the cylinder is large, an accumulator can be added between the valve and the cylinder to maintain pressure for 10-30 minutes. 3. You can add a small flow pump, the large pump after unloading, the small pump has been running, specifically for maintaining pressure.
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.
