Patent KR-20010106315-A (KR)
Inventor: JANG HONG YOUNG
IPC: E04H6/12
Filed: 2001-09-28
Abstract: This invention concerns a process for monitoring the degree of wear of a compression worm (8) which conveys a plasticized material, in particular, plastic, against an element that exerts a resistance and is located in a worm housing (4). To this effect, the pressure of the material conveyed is measured at two points disposed at intervals along the direction of travel. These two points are situated at both sides of a resistance body (12) towards which the compression worm (8) conveys. The difference between the two pressures measured is used to display the degree of wear of the worm (5) and its housing. A device for that purpose has an opening (18) which penetrates the wall (20) of the housing (4) of the worm (5) in the region of its thread or in a region immediately adjacent thereto. An additional opening (19) penetrates the wall of this housing (4); both openings (18, 19) are disposed axially at a distance from each other. A pressure sensor (22, 23) is linked to each opening (18, 19).
