Abstract

Plunger pump packing_seal pressure compensator is plunger pump technique, it adjusts to suitable pressure by pressure compensated pump plunger pump inlet or outlet pressure, to compensation fluid pressurization, the other end of the high pressure compensation Liquid transfer after supercharging to packing closed dielectric, just can offset pressure medium wholly or in part, using grease as compensation liquid, just sufficient lubrication can be carried out to packing.

Description

Plunger pump packing_seal pressure compensator
Technical field: the utility model relates to plunger pump technique, especially plunger pump packing_seal pressure compensator.
Background technique: plungers pump plunger sealing at present generally adopts packing_seal, whole media operation pressure is born because packing is unidirectional in sealed plunger work, and be in and do not lubricate or work under insufficient lubricating status, cause surface friction drag large, especially, when plunger pump conveying high-pressure power media, energy dissipation is high, and disable velocity is fast, change frequent, artificial, high material consumption.
Summary of the invention: the purpose of this utility model be to provide a kind of structure simple, the plunger pump packing_seal pressure compensator contrary with working pressure direction can be provided to packing, it adjusts to suitable pressure by pressure compensated pump plunger pump inlet or outlet pressure, to compensation fluid pressurization, the other end of the high pressure compensation Liquid transfer after supercharging to packing closed dielectric, just can offset pressure medium wholly or in part, using grease as compensation liquid, just sufficient lubrication can be carried out to packing.The purpose of this utility model realizes like this, it be enter exhaust chamber by water injection pump, feed liquor high-voltage tube, pressure compensated pump, discharge opeing high-voltage tube, one-way valve, spacer ring, packing box be formed by connecting, 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.
In one end of the pressure compensated pump pump housing, pump head is installed, and is fixed by connecting bolt; One end of pump head is provided with inlet opening; Be installed with piston in the centre of the pump housing, the dynamic chamber, side of piston, its opposite side has active chamber, and centre has seal ring to seal; In the middle top of the pump housing, oil ga(u)ge assembly is installed; Outage is had in the left side of the active chamber of the pump housing; There is oil hole at the left end of the pump housing, oil hole is installed with plug; Spacer ring is had with the joint of one-way valve in packing box; Spacer ring position letter body is holed, with feed liquor high-voltage tube the import of pressure compensated pump and plunger pump is entered 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.
Spacer ring has spacer ring inlet opening, the outside of spacer ring inlet opening is matrix, spacer ring inlet opening have interior intake chute below, interior intake chute have outer intake chute below; Packing indent is had at the end face of spacer ring.
During the utility model application, 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, packing box is entered by high-voltage tube after compensating liquid supercharging, enter packing and plunger seal position by spacer ring again, just can compensate packing_seal stressed.
The utility model compared with prior art has unique meaning: one is reduction of the pressure born packing local, significantly extends the working life of packing; Two is considerably reduce packing use amount, has saved resource; Three is rates when drastically reduce the area device maintenance, improves Utilization ratio.
Accompanying drawing illustrates: Fig. 1 is the structural representation of plunger pump packing_seal pressure compensator, and in figure 1, water injection pump enters exhaust chamber 2, feed liquor high-voltage tube 3, pressure compensated pump 4, discharge opeing high-voltage tube 5, one-way valve 6, spacer ring 7, packing box.
