Adjustment mechanism of Halter applied in pump unit for oil extraction

摘要

Adjustment mechanism of Halter applied in pump unit for oil extraction.The present invention patent describes a mechanism of adjustment of the halter applied in pump unit for oil extraction, which belongs to the field of the equipment used in oil exploration, understood by a rod (120) of the oil well which alters the length of the The rod (120).Reducing or increasing to compensate for the change course of pumping the pump unit (100), keeping the top of the shaft (120) always in the same position, without the need to stop the pump unit (100) when it has control of automatic course each change of course it is ne Necessary preparations.The adjustment mechanism of Halter applied in pump unit for oil extraction comprises a fixed body (10) equipped with a support device for fixing steel wire ropes (11) which are coupled to the head (110) of the pump unit (100).In the periphery of the fixed body (10) are arranged guides (12) which displaces the peripheral support, said guide (12) being provided for a position sensor (121) in the extreme upper portion.A mobile body (13) in the position of the fixed internal telescopic body has its course defined in relation to the movement of the head (110) of the pump unit (BU), moving in the same proportion of the movement of the head (110), said body (13) with mobile drive unit actuated by a elet Ro - water (20).
