Patent AT-E40100-T1: [Translated] PROCESS FOR MAKING CERAMIC CYLINDER SLEEVES FOR WELL PUMPS FOR GEOLOGICAL DRILLING.
Description
1. Method for the production of ceramic-cylinder sleeves of boring pumps for geological drilling, wherein a ceramic liner is produced with a maximum diameter of 180 mm, a maximum length of 280 mm, a wall thickness of 2-15 mm, an aluminium oxide content of at least 96%, a tensile strength of a least 3000 N/mm**2, and a heat resistance of at least 1600 degrees C and is fixed in a cylinder sleeve for example through a shrinkage process, characterized in that the ceramic suspension is shaped into a pot with a closed bottom and then is burnt in the first phase of burning-out at a temperature of 1450-1500 degrees C to a rest porosity value of 3-6%, that then the pre-burnt ceramic body is formed to the specified inside and outside dimensions of the ceramic liner, and then the second phase of burning-out ist done at a temperature of 1500-1700 degrees C, wherein the closed bottom part of the ceramic body having a pot form is cut away before inserting the ceramic liner into the cylinder sleeve.
