(El Salvador pusher hydraulic cylinder,produced by Hebei Hengyu company）
pusher hydraulic cylinder are widely used in El Salvador，because of excellent temperature resistance，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed pusher hydraulic cylinder for customers from El Salvador.
The piston rod and guide sleeve function of the pusher hydraulic cylinder is crucial: the relative motion pair between the piston rod and the guide sleeve is the main factor causing external leakage, if the chrome layer on the surface of the piston rod is spalling or producing longitudinal tensile marks due to wear, it will directly lead to the failure of the seal.
Repair method of small range wear of oil pusher hydraulic cylinder: 1. Use oxygen-acetylene flame to bake the scratched part (master the temperature, avoid surface annealing), bake the oil on the metal surface all the year round until no sparks splash; 2. The scratched part is treated with an Angle grinder, the grinding depth is more than 1 mm, and the groove is polished along the guide rail, preferably a dovetail groove. Scratch both ends of the drilling deeper, change the force situation; 3. Clean the surface with absorbent cotton dipped in acetone or anhydrous ethanol.
Disassembly pusher hydraulic cylinder: When disassembly pusher hydraulic cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the pusher hydraulic cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the pusher hydraulic cylinder.
At the rated pressure, the thrust of the pusher hydraulic cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the pusher hydraulic cylinder is related to the diameter of the pusher hydraulic cylinder, but not to the stroke of the pusher hydraulic cylinder. Moreover, the larger the pusher hydraulic cylinder diameter, the larger the area, and the greater the pressure obtained. To this point, we should have a correct understanding and clear understanding, so as to avoid problems in the use of the pusher hydraulic cylinder.
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.
How to calculate cylinder pressure?
Hydraulic pressure area of cylinder × hydraulic pressure = output force of cylinder 200mm=20cm 100mm=10cm 15Mpa=150Kg/cm2 Cylinder thrust: 3.14×10×10 area ×150 pressure =47100Kg=47.1t cylinder pulling force: 3.14×(10×10-5×5) Area ×150 pressure =35325Kg=35.325t The above calculation did not consider the resistance of oil return, because you did not provide oil return pressure. But the impact should be small.
