Abstract

The utility model discloses a packing box with a demountable fracturing pump head, aiming at overcoming the deficiencies of huge volume of the pump head of a hydraulic end assembly of the prior fracturing pump, great labor intensity and low work efficiency for replacing the hydraulic end assembly, and high production cost caused by the longtime shelving of replaced hydraulic end parts. The packing box comprises a pump head (3), a plunger piston (1), a sealing assembly (4) and a sealing gland cover (2). The sealing assembly (4) and the sealing gland cover (2) are arranged on the excircle of the plunger piston (1), and a packing box (6) is arranged between the sealing assembly (4) and the pump head (3). A pressure cap (5) of the packing box is arranged between the sealing gland cover (2) and the pump head (3). The pressure cap (5) of the packing box is fixedly arranged on the pump head (3), and the sealing gland cover (2) is fixedly connected with the pressure cap (5) of the packing box. The utility model has simple structure, is convenient to adjust the working pressure of the fracturing pump as well as replace and repair the plunger piston, improves the work efficiency, prolongs the service life of the pump head, and reduces the production cost.

Description

The detachable packing box of fracturing pump pump head
Affiliated technical field
The utility model relates to the used fracturing pump of a kind of petroleum production, especially relates to the detachable packing box of a kind of fracturing pump pump head.
Background technique
At present, the plunger of fracturing pump fluid end, sealing gland, seal assembly are installed in (as shown in Figure 1) on the housing with pump head, and the plunger in the work is by moving reciprocatingly along the plunger hole axis on the pump head, to the delivered downhole highly pressurised liquid.In application, the working pressure of fracturing pump should change with the needs of stratum structure and borehole pressure, and pressure range is 70~105MPa.Carry liquid pressure value to depend on fluid end structure and plunger size, the fluid end assembly that needs to change the different-diameter plunger satisfies the needs of carrying different pressures liquid.Because the pump head of the fluid end assembly of fracturing pump is bulky, Heavy Weight, it is big to change fluid end assembly labor intensity, needs crane gear and many people to cooperate and can finish inefficiency; The fluid end parts of replacing are shelved for a long time, and easily corrosion even scrap causes the cost of production height, causes the wasting of resources.
The model utility content
For the pump head of the fluid end assembly that overcomes existing fracturing pump bulky, Heavy Weight, it is big to change fluid end assembly labor intensity, inefficiency, the fluid end parts of replacing are shelved for a long time, cause the cost of production height, cause the deficiency of the wasting of resources, the utility model provides a kind of fracturing pump pump head detachable packing box.The detachable packing box of this fracturing pump pump head only need be changed parts such as packing box and plunger, and does not need pump head is unloaded the adjustment that just can finish the fracturing pump working pressure.
The technological scheme that its technical problem that solves the utility model adopts is: the detachable packing box of fracturing pump pump head, comprise pump head, plunger, seal assembly, sealing gland, seal assembly and sealing gland are installed on the plunger cylindrical, lubrication hole is arranged on the pump head, between seal assembly and pump head, packing box is installed, the packing box pressure cap is installed between sealing gland and the pump head, and the packing box pressure cap is fixedly mounted on the pump head; Sealing gland is fixedlyed connected with the packing box pressure cap; Have on packing box or the packing box pressure cap and the corresponding through hole of lubrication hole; Between packing box and the pump head endoporus seal ring is installed radially.
The beneficial effects of the utility model are, and are simple in structure, are convenient to adjust the working pressure of fracturing pump and the replacing and the maintenance of plunger, significantly reduce labor intensity, increase work efficiency, and help prolonging the working life of pump head, lower cost of production.
Description of drawings
Fig. 1 is existing fracturing pump pump head plunger scheme of installation.
Fig. 2 is the detachable packing box of a utility model fracturing pump pump head structural representation.
Among the figure: 1. plunger, 2. sealing gland, 3. pump head, 4. seal assembly, 5. packing box pressure cap, 6. packing box, 7. lubrication hole.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The detachable packing box of the utility model fracturing pump pump head comprises pump head 3, plunger 1, seal assembly 4, sealing gland 2, and seal assembly 4 and sealing gland 2 are installed on plunger 1 cylindrical, between seal assembly 4 and pump head 3 packing box 6 is installed; Between sealing gland 2 and the pump head 3 packing box pressure cap 5 is installed.Packing box pressure cap 5 is fixedly mounted on the pump head 3; Sealing gland 2 is fixedlyed connected with packing box pressure cap 5.
Provide lubricated by the lubrication hole on the pump head 37 for seal assembly 4, have on packing box 6 or the packing box pressure cap 5 and lubrication hole 7 corresponding through holes.Between packing box 6 and pump head 3 endoporus radial direction seal ring is installed also.
The detachable packing box of the utility model fracturing pump pump head, only need to change the plunger and the packing box thereof of different-diameter on the pump head, just can change the working pressure of fracturing pump, satisfy pressing crack construction operation needs, significantly reduce labor intensity, increase work efficiency, improve the utilization ratio of pump head, reduce operating cost.
