Technical field: the present invention relates to plunger pump technique, especially plunger pump packing_seal pressure compensator and application process.
Background technique: plungers pump plunger sealing at present generally adopts packing_seal, because packing is unidirectional in sealed plunger work, bear whole medium working pressures, and work under not lubricated or insufficient lubricating status, cause surface friction drag large, especially the in the situation that of plunger pump conveying high-pressure power media, energy dissipation is high, and disable velocity is fast, change frequently artificial, high material consumption.
Summary of the invention: the object of this invention is to provide a kind of simple in structure, can provide plunger pump packing_seal pressure compensator and the application process with working pressure opposite direction to packing, it adjusts to suitable pressure by pressure compensated pump plunger pump inlet or outlet pressure, to the supercharging of compensation liquid, high pressure compensation liquid after supercharging is transported to the other end of packing closed dielectric, just can offset wholly or in part pressure medium, grease liquid by way of compensation, just can carry out sufficient lubrication to packing.The object of the present invention is achieved like this, and it is by water injection pump, to enter exhaust chamber, feed liquor high-voltage tube, pressure compensated pump, discharge opeing high-voltage tube, one-way valve, spacer ring, packing box to be formed by connecting, and water injection pump enters exhaust chamber and is connected by feed liquor high-voltage tube with pressure compensated pump; Pressure compensated pump is connected by discharge opeing high-voltage tube with packing box, and has one-way valve at packing box and discharge opeing high-voltage tube joint; At pressure
Flow velocity safety valve is installed in the import of compensated pump.
One end at the pressure compensated pump pump housing is installed with pump head, and is fixed by connecting bolt; One end at pump head is provided with inlet opening; Centre at the pump housing is installed with piston, a dynamic chamber of side of piston, and its opposite side has active chamber, and there is seal ring sealing centre; Middle top at the pump housing is installed with oil ga(u)ge assembly; There is outage in left side at the active chamber of the pump housing; Left end at the pump housing has oil hole, and plug is installed on oil hole;
In packing box, there is spacer ring with the joint of one-way valve; On the letter body of spacer ring position, hole, with feed liquor high-voltage tube the import of pressure compensated pump and plunger pump, enter chamber or exhaust chamber is communicated with, pressure compensation delivery side of pump is communicated with letter body spacer ring position through hole at night.
On spacer ring, have spacer ring inlet opening, the outside of spacer ring inlet opening is matrix, spacer ring inlet opening have below an interior intake chute, interior intake chute have below an outer intake chute; End face at spacer ring has packing indent.
When the present invention applies, the highly pressurised liquid of plunger pump admission chamber or exhaust chamber enters pressure compensated pump power cavity by high-voltage tube, and promote piston to the compensation liquid supercharging in active chamber, after the supercharging of compensation liquid, by high-voltage tube, enter packing box, by spacer ring, enter packing and plunger seal position again, just can compensate packing_seal stressed.
The present invention compared with prior art has unique meaning: the one, reduced the pressure that bear packing part, and significantly extended the working life of packing; The 2nd, significantly reduced packing use amount, saved resource; The 3rd, rate while significantly having reduced device maintenance, has improved Utilization ratio.
