Description
Technical Field
The utility model relates to a water injection pump is used in oil field.
Background
The structure of a pump valve in the existing water injection pump is shown in figure 6: the large outer circle of a stuffing box in the stuffing box assembly is matched with an inner hole of the end face of the frame (H7/f7), and eccentric wear is avoided during linear motion of the plunger. The service life (more than 20MPa and oilfield sewage) of the sealing filler is 720 hours (national standard), namely about 30 days, the plunger sealing filler component needs to be replaced, and the method for replacing the filler comprises the following steps:
1: the screw A is removed, the stuffing box component is ejected out of the hole of the frame by a jackscrew, and because the material of the frame is HT250, the oil field sewage leaked from the sealing position of the plunger piston is not easy to be rusted at the matching position of the frame and the stuffing box, the oil field sewage is difficult to be removed. The oil field maintenance worker basically does not disassemble the packing box assembly, and only if the pressing thread of the packing box is damaged, the packing box assembly is disassembled to replace the packing box.
2: and (3) disassembling the pressing plate B, taking the valve component C out, taking the plunger D out, disassembling the compression nut E, and ejecting the sealing component out, wherein the work is completed on the pump, and the valve component is disassembled when the sealing component is replaced, so that the labor, the time and the physical power are wasted.
SUMMERY OF THE UTILITY MODEL
In order to solve the not enough among the prior art, provide one kind and alleviate intensity of labour, easy dismounting's stuffing box quick change structure water injection pump, the utility model discloses the technical scheme who adopts is:
the utility model provides a water injection pump of gland box quick change structure, is including installing the pump head in the frame the pump head in be equipped with the valves the pump head in be equipped with water inlet and delivery port the pump head be in the outer one end of frame and be equipped with the clamp plate the pump head on be in the frame in be equipped with the position sleeve with the relative one end of clamp plate, position sleeve one end stretch out outside the pump head the position sleeve on be equipped with the gland box and position sleeve in the activity be provided with the plunger and gland box between plunger and gland box on the gland box be equipped with and compress tightly the pressure disk on the position sleeve gland box hole equipartition have a set of separation blade gland box outer lane equipartition have a set of and separation blade complex terrace with arris, terrace with arris can follow and pass through between two adjacent separation blades.
Furthermore, the locating sleeve is fixed on the pump head through a bolt, and the pressure plate is connected to the frame through a bolt to compress the stuffing box.
Furthermore, the separation blade and the terrace with edge equipartition have three respectively.
Furthermore, the separation blade and the terrace with edge equipartition have four respectively.
Adopt the water injection pump of above-mentioned structure, because the pump head is arranged in to the stuffing box and is fixed through the position sleeve location outward, and compress tightly fixedly through the pressure disk, thereby the distance of stuffing box has been shortened, only need not become flexible pressure disk during the dismantlement, make the terrace with edge break away from separation blade clearance through rotatory stuffing box can take out the stuffing box, need not realize the dismantlement to the stuffing box through parts such as dismantlement clamp plate valves, make the dismantlement installation more convenient, the size of stuffing box has reduced weight simultaneously, labor intensity is reduced.

Detailed Description
As shown in fig. 1 water injection pump includes pump head 1, pump head 1 passes through the bolt-up to be fixed in frame X, be equipped with valves 2 in pump head 1, be equipped with water inlet 3 and delivery port 4 in pump head 1, it has clamp plate 5 to be used for the opening that 2 usefulness of shutoff installation valves to lie in the frame at pump head 1 one end outside the frame through the bolt fastening, it also is equipped with the opening and installs position sleeve 6 to lie in 5 one end of clamp plate in the frame on pump head 1, this position sleeve 6 passes through the bolt fastening on pump head 1, this position sleeve 6 one end stretches out outside pump head 1, be equipped with gland packing 7 on this position sleeve 6, the cover is equipped with pressure disk 10 on gland packing 7, gland packing 7 compresses tightly on position sleeve 6 in the frame through bolted connection to pressure disk 10, plunger 8 is then at gland packing 7 and 6 interior reciprocating motion, be equipped with seal assembly 9 between plunger 8 and gland.
The pressing of the pressure plate 10 on the stuffing box 7 is realized in the following way, as shown in figures 2 and 3, baffle plates 5-1 are uniformly distributed on the inner ring of the pressure plate 10, as shown in figures 4 and 5, prismoids 7-1 are uniformly distributed on the outer ring of the stuffing box 7, the baffle 5-1 is lapped on the prismatic table 7-1 to realize compaction, when in disassembly, the bolt for fixing the pressure plate 10 is loosened to enable the stuffing box 7 to rotate, the stuffing box 7 is rotated to align the gaps between each prismatic table 7-1 and the adjacent baffle 5-1, and the prismatic table 7-1 just can pass through the gaps between the baffle 5-1, so that the stuffing box 7 can be drawn out, since the combined overall length of the stuffing box 7 and the locating sleeve 6 in the structure is equivalent to the length of the stuffing box in the prior art, therefore, the overall length of the filling box in the structure is reduced, and the weight is reduced, so that the labor intensity is reduced, and the disassembly is convenient and quick. The baffle 5-1 and the frustum pyramid 7-1 shown in fig. 3 and 5 are generally uniformly distributed in a four-lobe manner, and can be uniformly distributed in a three-lobe manner.
