Abstract

The invention refers to a downhole piston pump for the exploitation of the oil, used in the extraction of hydrocarbons from the productive layers of the oil wells by sucker rods. The pump according to the invention consists of a drive head (2) which is mounted on a polish rod (4) for driving the piston of the pump and is provided with two nuts (3), polish rod (4 ) drive passing through a conducting nut ( 8) made of graphite bronze and the nine sealing nuts ( 9 and 10) also made of graphite bronze, in the channels are introduced a special oil-resistant grease (11) and the nut (8 and 9) that seal on the polished rod (4) are supported on a shaft (12) which is leaning on another adjustable guide nut (13) which is adjusted and fastened with three pins(14) adjusting the nut (8 and 9) for sealing and guiding is made with a threaded nut (5) which is screwed into a shell (15) and the ensure is made with two nuts (6 )which are stamped, stopped in a ring (7) and in the shell (15) of the sealing box, a spherical (16) bolt is screwed in which is secured with a nut (17) on the spherical bolt (16), the assembly consisting of a spherical ring (2G) being mounted on a spherical guide ( 21), is mounted on the spherical bolt (16) with the support of six screws (18 ) and six elastic shaft (19) the pump further using a multiple relief valve which is formed by a bracket (33) of the valve on which the seat (32) of the valve, six balls (31), is initially mounted, a block (30) with springs in which initially there were mounted six adjusting shaft (27), six springs (28), six guides (29) of the springs, a closing flange (6), in which six adjusting pins (25) and six shock absorbers (24) are mounted, all of them centering is with two positioning pins (34) and Is secured with two nuts (23) after which the spherical guide is mounted and secured with a nut (22).
