In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a novel combination formula stuffing box for high-speed pump, includes pump head and power end box, the stuffing box is installed to one side of pump head, install ceramic plunger jointly on pump head and the power end box, be equipped with first spacing groove on the stuffing box, first spacing inslot is installed first O shape sealing washer, be equipped with the second spacing groove on the stuffing box, second O shape sealing washer is installed to the second spacing inslot, be equipped with the fourth spacing groove on the stuffing box, fourth O shape sealing washer is installed to the fourth spacing inslot, be equipped with the mounting groove on the stuffing box, install the plunger seal in the mounting groove, the cooling water ring is installed to one side of stuffing box, the one end of cooling water ring is contradicted in the sealed one side of plunger, the gland is installed to one side of cooling water ring, and installs the cooling water seal on the gland, ceramic plunger runs through the setting at the pump head, The packing box, the plunger seal, the cooling water ring, the cooling water seal, the gland and the power end box body.
Preferably, the ceramic plunger is fixed by a plunger bolt.
Preferably, a fifth limiting groove is formed in the gland, and a fifth O-shaped sealing ring is installed in the fifth limiting groove.
Preferably, a third limiting groove is formed in a cooling water pore passage of the pump head, and a third O-shaped sealing ring is installed in the third limiting groove.
The utility model discloses adopt integrated configuration on packing box structural design, not only improved the leakproofness when the plunger moves, still guaranteed the stability of its continuous operation time, improved the life of part, reduced the number of times of maintaining simultaneously, improved work efficiency, the practicality is strong.

In the figure: the plunger piston comprises a ceramic plunger piston 1, a plunger piston bolt 2, a first O-shaped sealing ring 3, a second O-shaped sealing ring 4, a third O-shaped sealing ring 5, a packing box 6, a fourth O-shaped sealing ring 7, a cooling water ring 8, a fifth O-shaped sealing ring 9, a gland 10, a plunger piston seal 11 and a cooling water seal 12.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-3, a novel combined stuffing box for a high-speed pump, in fig. 1, a ceramic plunger 1 and a plunger bolt 2 are coaxially mounted, and are fastened with a power end intermediate rod through the plunger bolt 2, the left side of a stuffing box 6 is embedded into a pump head, and is in a coaxial mounting state, the stuffing box 6 compresses a first O-shaped sealing ring 3 when being compressed on the pump head, and when the ceramic plunger 1 moves forwards and is in a high-pressure liquid drainage state, the first O-shaped sealing ring 3 bears high pressure.
The utility model discloses in, second O shape sealing washer 4 and first O shape sealing washer 3 are respectively according to the corresponding mounted position at gland packing 6, bear the high-pressure damage back for a long time when first O shape sealing washer 3, form encapsulated situation by second O shape sealing washer 4 at gland packing 6 left side circumference surface, consequently, this structure has been avoided only setting up single high-pressure seal and has damaged the back, the high-pressure pump need be maintained promptly and is changed sealedly, the reliability of sealing is improved, long time has been used to the relevant part of having improved, the stability of high-pressure pump continuous operation has been guaranteed.
The utility model discloses in, high pressure plunger seal 11 installs in the hole of packing box 6 to compress tightly through cooling water ring 8, cooling water ring 8 compresses tightly the other end and is gland 10, and gland 10 left side is pressed cooling water ring 8, and the opposite side is installed in the corresponding round hole of power end box.
The utility model discloses in, among the hole of gland 10 is installed to cooling water seal 12, accomplish the cooling water seal effect, fourth O shape sealing washer is installed in the outside ditch inslot of packing box 6, the outside ditch inslot of gland 10 is installed to fifth O shape sealing washer 9, fourth O shape sealing washer and fifth O shape sealing washer 9 accomplish the sealing function of cooling water in cooling water ring 8 both sides respectively, as shown in fig. 2 and 3, the cooling water gets into power end box cooling water pore from the pump head cooling water pore, rivers reach the plunger surface through the rivers pore of cooling water ring 8, cool off.
