How to test the pressure of the telescopic hydraulic cylinder
Telescopic hydraulic cylinder is the most popular cylinder type in many construction industry, According to the nominal pressure of the cylinder, the maximum allowable pressure refers to the maximum pressure that the cylinder can withstand instantly, and the resistance test pressure refers to the test pressure that must resist 1.5 times the nominal pressure when checking the quality of the cylinder, where V is the amount of oil consumed in the stroke of the cylinder piston rod, t is the time required for the cylinder piston to move once, and v is the speed of the piston rod. A is the speed of the piston rod, and the stroke of the piston refers to the distance between the poles when the piston corresponds.
Usually, after meeting the cylinder stability requirements, the standard competition similar to the actual competition is selected according to the actual work competition, the moving speed is the pressure is the distance to push the piston, the size specifications mainly include the inner and outer diameter of the cylinder barrel, the diameter of the piston rod and the size of the cylinder head, these dimensions are based on the working environment and installation mode of the cylinder, and need to provide force and push and pull stroke, etc. After cleaning the cylinder with diesel or kerosene, grease it and wrap it in oil paper, preferably in a wooden box, and store it in a dry, non-corrosive environment.
Not only Anbao Group could manufacture all kinds of hydraulic cylinders according to the drawing from our customers,but also we could make a design according to customer’s requirements.If you require our engineer to make a design,please advise us the following specification:
