FIELD: oil industry.
SUBSTANCE: invention relates to oil and gas industry and can be used for protection of power cable of pump from mechanical damage. Device comprises a two-component housing, a detachable tool joint with fastening elements and a protective screen. Housing consists of pivotally coupled housing and bracket, interconnected by hinged bolt and adjusting screw, screwed into housing and connected to bracket by axis. Adjusting screw may be regulated axially due to screwing in/out into/from housing when diameter of pump neck changes. Detachable tool joint is made as a hinged bolt and a hold-down nut, with uncontrolled screwing lock washer. Furthermore, housing on one side is equipped with grooves Doc1 and Doc2 for landing on different-size pump bases or housing of hydraulic protection, on other side - slot b3, support plane B1 and four bosses b1, b2, b3 and b4, as well as grooves DF1, DF2 and DF3 for landing on different-size flanges heads of electric centrifugal pumps. Slot, support plane and bosses are made on special lugs of housing having thickness cl.
EFFECT: technical result is improved reliability of protectolizer fixation at pump neck, improved versatility of device.
