Abstract

The invention relates to a packing adjusting system and method, and relates to the field of oil and gas equipment. The packing adjusting system comprises a control system, a driving system, a packing pressing cap tightening device and a packing pressing cap, the control system is used for sending a driving signal to the driving system; the driving system is used for receiving the driving signal sent by the control system and driving the packing pressing cap loosening and tightening device to move according to the driving signal; and the packing pressing cap loosening and tightening device is used for screwing or unscrewing the packing pressing cap under the driving of the driving system. The packing structure is used for solving the problem that the packing is pressed instably.

Description

technical field [0001] The present application relates to the field of oil and gas equipment, in particular to a packing adjustment system and method. Background technique [0002] At present, in the oil and gas field operation site, the packing gland of the plunger pump adopts the method of mechanical anti-loosening or regular packing gland pre-tightening. [0003] The method of mechanical fixing and anti-loosening can ensure that the pressure cap will not loosen, but the pressure of the pressure cap on the packing during this process will change with the long working time. If the packing wears quickly, it will cause the packing to be squeezed If the packing force is reduced, the sealing effect will be affected; if the sediment on the end face of the valve box increases, the space of the packing will be compressed, resulting in an increase of the extrusion force on the packing, which will have a great impact on the service life of the packing. influences. [0004] In addi...
