Hydraulic cylinder It is one of the key words in the web, and there are different kinds of hydraulic cylinder products. Therefore, in order to enable everyone to use the hydraulic cylinder accurately, the above will develop the further education work of this product, that is, to explain relevant knowledge and answer questions, so that everyone can have a further education mode, and then reach the policy.

1. How to change the hydraulic cylinder oil seal?

To reform the oil seal in the hydraulic cylinder, in detail, we should first remove the guide sleeve on the hydraulic cylinder, and then take out the piston rod and piston. In the future, we should be able to remove the oil seal in each part and replace it with a new oil seal. How can we accomplish the task of reform and prevent the problem of title in the process of change.

2. Process flow of cylinder barrel, piston and guide sleeve in hydraulic cylinder

The processing flow of the cylinder barrel in the hydraulic cylinder is as follows:

(1) Material preparation (seamless steel pipe) - maintenance - tempering - turning (turning excircle, shelf opening, boring seam, flange seam, etc.) - hardening and tempering hardness testing - welding (welding receiving and probing seat, flange and other accessories) - boring or honing (rough boring, fine boring, rolling) - turning (hole clamping groove or thread pattern inside the table) - fitter (oil hole) - maintenance - rust prevention warehousing

(2) Material preparation (forging) - testing - welding - welding flaw detection - rough turning - quenching and tempering - turning (turning excircle, frame mouth, boring seam, flange seam, etc.) - quenching and tempering hardness testing - welding (welding collar receives search seat, flange and other accessories) - boring or honing (rough boring, fine boring, rolling) - turning (hole clamping or internal and external threads) - fitter (oil drilling mouth) - grinding - rust prevention warehousing

The processing flow of the piston and guide sleeve in the hydraulic cylinder is as follows:

(1) Material preparation (casting, forging) - test (material certificate, forging flaw detection, etc.) - rough turning - fine turning - test - rust prevention warehousing

(2) Material preparation (round steel) - test (material certificate, etc.) - rough turning - fine turning - inspection - rust prevention warehousing
