SU1308749A1 - Rigid reflector of hydraulic waves - Google Patents

Abstract

The invention relates to hydraulic impact machines in the mining industry and allows to increase the reliability and efficiency of the reflector by adjusting the length of the reflective cavity (OD) and prevent jamming of the adjustment rods (PC) 22 in the deadlock chamber (K). The reflector includes a housing 2 with an axial channel of 12 and three K. One (L

Description

the supply line K communicates with the channel 12, and the other two (7.8) in the upper part communicate with each other and form an OP, the radial-longitudinal ribs 4-6 of the housing 2 form with it K, and junction 11 is connected to its lower part and has a prism guide 14 with a transverse hole. It is located in the OP at the bottom of the dead end K. Inclined channels 15 of the adapter 11 are in communication with the inlet K and OP. For adjusting the length of the OD, case 2 contains removable in-situ housings located in the dead end. The invention relates to mining industry, in particular, to water hammer machines operating in a wide frequency range with rigid reflectors of hydraulic waves when drilling wells.

The purpose of the invention is to increase the efficiency (|) of work by adjusting the length of the reflective cavity, increasing reliability and warning, and jamming the adjusting rods in the deadlock chamber.

The rigid reflector of hydraulic waves consists of the upper adapter 1, the housing 2 with the sealing ring 3, the radial-longitudinal ribs 4-6 forming with the housing 2 a single rigid structure with chambers 7-9. The chambers 7 and 8, which are hydraulically interconnected in the upper part of the rib 4 by the window 10, form a reflective cavity. A lower adapter 11 with an axial channel 12 is screwed onto the body 2, the figured base 13 is pressed to the body, with a guide prism 14 with a transverse, through hole, an inclined channel 15 and a smooth transition 16 into the reflection cavity of the chamber 7, and an inclined channel ( not shown),. connected to the channel 15 by the hole 17 and a similar smooth transfer

PCs with a prism 25 at the top and a groove at the bottom, in the bottom prism. They are fastened with pins 29. The upper PC 22 has a groove under the sealing collar 28. During the work of the reflector, the flushing fluid is supplied through the drill pipe, adapter 1, supplying K, channels 18 and 12 to the hydropercussion machine. Hydraulic waves pass through channels 12, 18, 15 K 7.8. Reflected in the OP, they return to the machine exactly at the stroke phase. 1 hp ff, 4 sludge

by moving 16 to chamber 9 for supplying washing liquid to the hydraulic shock machine through the axial channel 18 of the process sleeve 19 with sealed calts 20 and 21. Adjusting the length of the reflective cavity are adjustment rods 22, one of which is mounted in a longitudinal groove 23 with a transverse through hole 24 on guide prism 14 and at the top has a similar prism 25 with a transverse through hole 26, which is mounted on the groove, analogous to the groove in the rod 22, removable dead end 27 with sealing

cuff 28. Details 14, 22 and 27 in the collection are fastened with pins 29.

The device works as follows.

On the surface, by means of removable, unequal, adjusting rods 22, is established according to the frequency of operation of the hydraulic hammer, the length of the reflection cavity is necessary. At the same time, the parts assembled 22, 27 and 29 together with the upper parts of the figure-shaped base 13 are inserted into the corresponding reflector chamber and the adapter 11 is screwed onto the body 2. The gear with the water hammer and the reflector is lowered into the well. Wash fluid is supplied through drill pipes connected to adapter 1 through openings 17 and chamber 9 through inclined channel 15 of figured base 13J to axial channels 18 of technological sleeve 19 and 12 of adapter 11 into

water hammer machine. The hydraulic waves generated during the operation of the hydraulic shock pass through channels 12, 18 and 15, a smooth transition 16, chambers 7 and 8 and, reflecting from the dead end fitting 27 of the reflective cavity, the length of which is adjusted according to the frequency of operation. hydraulic shock machine, return to the machine exactly at the phase of the working stroke.
