The maintenance of the oil cylinder and the characteristics

The maintenance of the oil cylinder and the characteristics of the pipe bender  

Maintenance of hydraulic cylinder of pipe bender:  

First of all, you have to get to know what you need to dismantle the hydraulic cylinder, of course, before demolition to first survey.  Preparing for later assembly.  In particular, the position of the oil mouth and the placement size.  

Then you can remove the cylinder bottom, cylinder head and guide sleeve.  Take out the piston rod from the cylinder, and prevent the piston rod from being injured during the collision.  Then come down and remove the piston.  The piston is usually threaded together, but there will be a stop screw. Remove the stop screw first.  Finally remove the sealing ring.  

When a hydraulic system has a plurality of hydraulic cylinders, it is necessary to connect a valve at the pump outlet to ensure that each hydraulic cylinder can not only normal things, but also when some things are not, the whole system of tranquility.  

A solenoid relief valve can be installed.  This valve can control the pressure of your entire system and can be opened to relieve pressure when the cylinder does not rise above the nominal pressure.  Under nominal pressure this valve closed hydraulic cylinder can work normally.  And can be electronic control overflow smooth and easy to use.  

Features of pipe bender:  

This process can avoid the uneven phenomenon of pipe bend wall thickness caused by the tension thinning of the convex edge of pipe wall and the compression thickening of the concave edge of pipe wall.  

By using this process, 180 elbow with uniform wall thickness of small radius (R≈D) and thin wall (T /D≈0.015) can be produced, which cannot be achieved by other bending processes.  

If the design of various technological parameters is reasonable, the thickness of the pipe wall in each part of the bending pipe forming process can be kept constant, that is, it is always equal to the thickness of the straight pipe before deformation.
