Regulators, gauges and tanks available as accessories. The high pressure port is connected by a conduit to a regulator delivering high pressure gas above about psig and preferably above about psig. The outlet port connects to the power end of the gas motor through a conduit not shown to deliver high pressure air to the motor during the power stroke and to exhaust air from the motor during the retraction part of the power cycle. For example, many high pressure, high volume gas wells have a tendency to freeze up downstream of the production choke located in the Christmas tree. You are commenting using your Facebook account. Rigid with the rocker arm assembly 68 is an actuating arm 76 which alternately pulls and pushes on a pair on linearly movable valve actuating assemblies Year of fee payment:
The hexsteam injector of claim 12 wherein the rocker arm section comprises a slot receiving the valve rod therein. The opposite end of the spring 64 is attached by a similar connecting means 66 to a rocker arm or crank assembly 68 having a shaft 69 mounted by a bearing 70 on texstteam post 72 for rotation about an axis The liquid pump end is of conventional design and may be substantially as previously described. It will be seen that the embodiment of FIG. A prototype of the embodiment of FIGS.
The housing segment includes a high pressure inlet port connected by passagesto an openinglocated intermediate the ends of the valving passages Preferably, the stops,are adjustably mounted on the valve rodsas by threading the outer end of the valve rod and threadably advancing the stops,to a desired position.
The popular models among Texsteam pumps are the,models and for Flomore pumps, the, the series and the Flomore MPC series always in great demand. The standard approach of the industry is to use a smaller pumpp end, i.
Thus, this invention contemplates a chemical injector having a more-or-less conventional gas motor end, a more-or-less conventional liquid pump end and an improved gas distribution system for delivering high pressure gas to the gas motor end.
EQU2 This value, in reality, is the pressure differential required across the gas motor piston or diaphragm. Silahkan melakukan transaksi dengan cara buat permintaan beli, terima penawaran, beli dari penawaran serkes Anda terima dan bayarkan biaya ke Indotrading.
USA – Chemical injector pump – Google Patents
Powered by diaphragm motor with spring return. A retaining nutis threaded onto the end of the valve rods It will thus be seen that the valve and seat member moves for a very short distance, e.
The piston 46 preferably includes a pair of spaced O-rings 50 providing a seal against the inside of the cylinder Making anything that will operate for 5, cycles without breaking down is no small feat. Email required Address never made public. Reversal is accomplished by a direct spring-actuated plunger switching mechanism rotary three-way valve.
Chemical Injection Pumps
Lubrication and sealing of a free floating piston of hydraulically driven gas compressor. This application is a continuation of application Ser. Additional sealing O-rings seal around the exterior of the valve rod as its exits through the connection The outlet port connects to the power end of the gas motor through a conduit not shown to texsteamm high pressure air txsteam the motor during the power stroke and to exhaust air from the motor during the retraction part of the power cycle.
In other embodiments, the chemical injector pump includes a liquid pump end, a gas motor end, and a high pressure position responsive valve for directly delivering high pressure gas to the gas motor.
Thus, control air enters through the port 96, moves through the passage 94 and the valving passage 90 and exits through the passage and vent port Another object of this invention is to provide an improved chemical injector pump which uses higher pressure gas to drive the gas motor. By continuing to use this website, you agree to their use. Daftar Sekarang Hubungi Often, gas pushed out of the gas motor end is throttled to control the speed of the pump which means that the pressure on the inlet side of the gas motor must be higher.
In a second embodiment of the invention, high pressure air or natural gas is controlled directly by a position responsive valve to directly deliver high pressure gas to the gas motor end and to control the exhaust of gas from the gas motor end. When the valve 16 is manipulated by the actuating arm 76 to shift the assemblies 78, control air is delivered to the pilot valve 18 to deliver power air through the line to the air cylinder These pumps fill the requirements of a broad range of applications because of their ability to achieve high discharge pressures up to 12, psi and wide volume ranges.
A branch line connects the conduit to the pilot operated valve 18 while a common conduit connects the power gas outlet and the vent inlet to the inlet of the air motor As shown in FIG. A horizontal plunger and vertical check valve arrangement assure high operating efficiency.
The liquid seriew capacity of a chemical injector pump is increased substantially by using high pressure gas to drive the gas motor.
It will be seen that manipulation of the switching valve cyclically and alternately connects the outlet port with the power air inlet and with the vent port thereby causing the air motor to alternately extend on the power stroke and retract and thereby cyclically operate.
When the valve rod is fully retracted, the O-ring prevents power air from moving to the port and the motor while air is being exhausted through the port and passage It is an pu,p of this invention to provide an improved chemical injector pump. Rizky Adhi Pratama has a wide range of options available for pmup injection pumps which are useful for a large number of industries. In one embodiment, the chemical injector pump includes a liquid pump end, a gas motor end, a low pressure position responsive valve, and a high pressure pilot operated valve manipulated by the seriez pressure valve for delivering high pressure gas to the gas motor.
