Abstract
The utility model relates to a middle-high pressure outlet plunger pump head structure for a metering pump. The structure comprises a plunger (1), a pump head (2) and a seal box (4), wherein the plunger (1) is arranged in the pump head (2), and the seal box (4) is arranged between the plunger (1) and the pump head (2). The structure is characterized in that the structure also comprises a front packing set (3), a back packing set (5), an adjusting cap (6) and a pressure source access port (7); the front packing set (3) and the back packing set (5) are arranged between the plunger (1) and the pump head (2); the front packing set (3) is arranged on the front end of the seal box (4); the back packing set (5) is arranged behind the seal pack (4); and the pressure source access port (7) is arranged in the pump head (2) and is communicated with the seal box (4). Compared with the prior art, the structure is advantaged by capability of increasing the promised maximum value of inlet pressure.
Description
Technical field
The utility model relates to a kind of metering pump, especially relates to a kind of metering pump mesohigh import plunger pump header structure.
Background technique
The lower rotary pump equipment of the multiplex efficiency of recycle pump of existing import Intermediate High Pressure, and the high metering pump of fewer utilization efficiency, its main cause is that metering pump has larger restriction to maximum inlet pressure, generally speaking, it when the inlet pressure of metering pump is greater than 10MPa, is import Intermediate High Pressure, using metering pump for the higher situation of inlet pressure, tending to because the overheated problem of pumping that causes of drive end driving mechanism causes damage; If adopt replacing drive end to solve this problem, high cost, and there is no versatility.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of working stability reliable in order to overcome the defect that above-mentioned prior art exists, insensitive to particle, mesohigh import plunger pump header structure for the metering pump of long service life.
The purpose of this utility model can be achieved through the following technical solutions: mesohigh import plunger pump header structure for a kind of metering pump, and plunger, pump head, sealed letter, described plunger is arranged in pump head, between plunger and pump head, is provided with sealed letter; It is characterized in that, also comprise front filler group, rear filler group, adjustment cap, pressure source access port, described front filler group and rear filler group are all arranged between plunger and pump head, and front filler group is positioned at sealed letter front end, rear filler group is positioned at sealed letter rear portion, described pressure source access port is arranged on pump head, and communication seals letter;
Medium enters by the medium that is arranged on pump head front end, pressure source medium is introduced pump head by pressure source access port, when plunger moves forward, front filler group sealing medium, rear filler group sealing load source medium, pressure source medium enters sealed letter, and medium and pressure source medium are exerted pressure to plunger simultaneously, reduce the pressure difference at plunger two ends; When plunger moves backward, front filler group sealing medium, rear filler group sealing load source medium, pressure source medium is discharged sealed letter, further reduces the pressure difference at plunger two ends, thereby improve inlet pressure, agrees maximum value.
Described medium import and export, front filler group, pressure source access port, rear filler group are located on pump head successively.
On described pump head, be also provided with lubricant oil and splash into mouth, this lubricant oil splashes into a mouthful communication seals letter.
After described rear filler group, be provided with adjustment cap.
Compared with prior art, the utility model, by introducing import or export pressure source, carrys out the pressure difference at balance plunger two ends, thereby greatly improve inlet pressure, agrees maximum value.
Accompanying drawing explanation
Fig. 1 is the utility model metering pump mesohigh import plunger pump header structure schematic diagram.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Embodiment
As shown in Figure 1, mesohigh import plunger pump header structure for a kind of metering pump, plunger 1, pump head 2, sealed letter 4, described plunger 1 is arranged in pump head 2, between plunger 1 and pump head 2, is provided with sealed letter 4; Also comprise front filler group 3, rear filler group 5, adjustment cap 6, pressure source access port 7, described front filler group 3 and rear filler group 5 are all arranged between plunger 1 and pump head 2, and front filler group 3 is positioned at sealed letter 4 front ends, rear filler group 5 is positioned at sealed letter 4 rear portions, described pressure source access port 7 is arranged on pump head 2, and communication seals letter 4; Described medium import and export (medium import 9, media outlet 10), front filler group 3, pressure source access port 7, rear filler group 5 are located on pump head 2 successively.On described pump head 2, be also provided with lubricant oil and splash into mouth 8, this lubricant oil splashes into mouthful 8 communication seals letters 4.Described rear filler group 5 is provided with adjustment cap 6 below.
Medium enters by the medium that is arranged on pump head 2 front ends, pressure source medium is introduced pump head by pressure source access port 7, when plunger 1 moves forward, front filler group 3 sealing mediums, rear filler group 5 sealing load source media, pressure source medium enters sealed letter, and medium and pressure source medium are exerted pressure to plunger 1 simultaneously, reduce the pressure difference at plunger 1 two ends; When plunger 1 moves backward, front filler group 3 sealing mediums, rear filler group 5 sealing load source media, pressure source medium is discharged sealed letter 4, further reduces the pressure difference at plunger 1 two ends, thereby improve inlet pressure, agrees maximum value.
