A joint 1, a plunger casing 2 and the pump body 3 are connected successively, the pump body 3 is connected with the lower control body 8 by a double-male joint 12, the upper control body 5 is positioned above the lower control body 8, and an outlet joint 18 is connected with the plunger casing. The utility model has the advantages that: the natural gas under certain pressure in the gas gathering station can be effectively used as power source for driving the pump, thus the power consumption in the gas gathering station can be reduced greatly; the intermediate action links can be reduced to improve working efficiency and functional reliability and to lower labor intensity of workers; the amount of leakage points is decreased, meanwhile the sealing reliability is improved to meet the requirements of the HSE management.
Description
Technical field
The utility model relates to a kind of highly pressurised liquid pumping equipment, specifically, is a kind of pneumatic metering pump.
Background technique
The gas field produces and takes high-pressure gas collection, concentrates and annotate pure technology, injects a certain amount of methyl alcohol in pit shaft and surface line, to avoid forming hydrate and blocking pipeline in the production process.At present, filing provision is a plunger metering pump, and this pump needs electricity consumption as power source, has increased gas gathering station internally-powered consumption; And this equipment causes higher rate of fault owing to there is more intermediary movements link, has increased labor strength.
Technology contents
The purpose of this utility model is to provide a kind of rock gas that can effectively utilize certain pressure in the gas gathering station as power source, driven pump work, thus reduce station internally-powered consumption greatly; Reduce the intermediary movements link simultaneously,, reduce labor strength to increase work efficiency and functional reliability; Reduce leak source, improve sealing reliability simultaneously, with the pneumatic metering pump of the needs that satisfy the HSE management.
The utility model is finished like this:
Comprise inlet union 1, plunger housing 2, the pump housing 3, pump cover 4, control upper body 5, regulate bolt 6, small piston 7, control lower body 8, pump ball-valve 9, valve seat 10, spring 11, two tool joint pin 12, big piston 13, spring 14, plunger 15, pressure cap 16, Sealing 17, outlet connection 18, joint 1, plunger housing 2, the pump housing 3 connect successively, the pump housing 3 connects by two tool joint pin 12 control lower bodies 8, control upper body 5 is arranged on the control lower body 8, and outlet connection 18 is connected with plunger housing 2.
The utility model also adopts following technological scheme:
The pump housing 3 inner plunger 15, spring 14 is arranged at plunger 15 outer tops, and Sealing 17 is arranged at plunger 15 outer bottoms, and pressure cap 16 is arranged on the Sealing 17, and big piston 13 is arranged at the top of plunger 15.
In the control lower body 8 two ball valves 9, valve seat 10, spring 11 are arranged, two ball valves 9 are located on the valve seat 10, and there is spring 11 its underpart.
Control has the bolt 6 of adjusting, small piston 7 respectively in the upper body 5.
Pump cover 4 is arranged on the pump housing 3.
Advantage of the present utility model is:
The rock gas that can effectively utilize certain pressure in the gas gathering station is as power source, driven pump work, thus reduce station internally-powered consumption greatly; Reduce the intermediary movements link simultaneously,, reduce labor strength to increase work efficiency and functional reliability; Reduce leak source, improve sealing reliability simultaneously, to satisfy the needs of HSE management.
Now succeed in developing float amount pneumatic metering pump, and carried out indoor and site test.Every performance index have reached designing requirement, stable and reliable operation.The pneumatic metering pump does not need electrical actuation power, can reduce the power consumption in the gas gathering station greatly, is convenient to the workman and carries out equipment control.Characteristics such as in addition, the pneumatic metering pump volume is little, and noise is little, and installation and maintenance are simple all have been subjected to on-the-spot favorable comment.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Concrete enforcement
The pneumatic metering pump mainly is made up of control section and working portion two-part.Control section mainly comprises control upper body 5, small piston 7, two ball valve, control lower body 8 and regulates bolt 6 that working portion mainly comprises inlet union 1, the pump housing 3, big piston 13, plunger 15, Sealing 17 and outlet connection 18.The rock gas that enters the pump housing 3 is divided into two-way, and one the tunnel enters control upper and lower body 5,8, makes small piston 7 reciprocating, and another road enters active chamber, makes plunger 15 reciprocating.The to-and-fro motion of small piston 7 has realized the continuous commutation (being to-and-fro motion) of plunger 15, and the to-and-fro motion of plunger 15 has realized the suction and the discharge of liquid medium.Control volume adjusted bolt 6 can realize that liquid displacement is by the zero stepless setting to rating value.
Pneumatic control partly is a key of the present invention, mainly comprises control upper body 5, small piston 7, two ball valve 9, control lower body 8 and regulates bolt 6.
The gas of certain pressure is by suction port, and the runner on small piston 7 enters in the cavity of control lower body 8; When gas entered big piston 13 chambeies through two tool joint pins 12, the shunting of fraction gas entered in small piston 7 chambeies of control upper body 5, and it is descending to promote small piston 7, and at this moment, big piston 13 is also descending, finished the discharge opeing action; Small piston 7 comes downwards to two ball valves 9, and two ball valves 9 are opened, and large and small piston 13,7 intracavity gas are discharged through relief opening; When cavity pressure dropped to certain value, spring 11 was closed two ball valves 9, and control lower body 8 cavity pressures raise, and it is up to promote small piston 7, and at this moment, big piston 13 is also up, finishes the feed liquor action; When small piston 7 walked to control 5 tops, upper body, control section was finished the one action circulation.The spinning in and out may command of adjusting bolt 6 enters the tolerance in small piston 7 chambeies, regulates small piston 7 frequency of okperation, thereby regulates pump displacement.
