The pressure maintaining device for the reciprocating type mud pump is simple in structure, low in manufacturing cost and convenient to install, and only a tee joint and a reducing joint need to be additionally arranged on a pipeline; the inflatable rubber capsule can be adjusted specifically according to different pressures. The production practice shows that the pressure maintaining device for the reciprocating type mud pump is simple and effective, convenient to use, and obvious in economic benefit and social benefit.
Description
Technical field
The utility model relates to stable-pressure device, specifically, is a kind of stable-pressure device for piston high-density pump that reduces piston high-density pump pump pressure pulsation in service.
Background technique
Piston high-density pump is one of capital equipment of core drilling engineering, and its effect is to provide the cooling drill bit of highly pressurised liquid (water), in the Hydraulic and Hydro-Power Engineering prospecting, is also the capital equipment of water pressure test in borehole usually.Piston high-density pump mainly is comprised of transmission system (gear), connecting rod, pump head (inlet valve, drain valve), frame.The piston of piston high-density pump is realized the linear reciprocating motion in pump chamber by transmission system (gear) and connecting rod, thereby changes volume realization water suction and the draining of pump chamber.The fluid pressure of piston high-density pump output has pulse characteristic.The pulse of fluid pressure affects the working life of pipeline, the correct collection of impact to test data in water conservancy and hydropower drilling project water pressure test in borehole.As shown in Figure 1, in order to reduce the pulse of pressure, prior art is to install an air chamber as stable-pressure device 3 on the outlet pipe 4 of piston high-density pump 2, the pressurized vessel that described stable-pressure device 3 is a cavity, be provided with through hole 5 in the bottom of pressurized vessel, the through hole 5 of pressurized vessel is connected on outlet pipe 4 by three-way pipe.1 is intake pipe.
Its principle of stabilized voltage is that the compression property of application gas is subdued crest and the trough with compensatory pressure pulsation liquid, realizes the stable of pressure.When the water pressure of discharging when pump is large (crest), the high pressure water in outlet pipe 4 makes the air compressing of air chamber, and air pressure increases, and water pressure reduces; When the water pressure hour (trough) that pump is discharged, the air spreading of air chamber, air pressure reduces, and water pressure increases.Thereby reduce the water pressure fluctuation in outlet pipe 4.
But, the stable-pressure device of prior art (pressurized vessel), the air in pressurized vessel with the liquid in outlet pipe without separating, pump is in operation, liquid in outlet pipe is often invaded in pressurized vessel, in outlet pipe 4, causes voltage regulation result poor part Bas Discharged in the air chamber pressurized vessel.
The model utility content
Technical problem to be solved in the utility model is that a kind of stable-pressure device for piston high-density pump that reduces piston high-density pump pump pressure pulsation in service is provided.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of stable-pressure device for piston high-density pump, described stable-pressure device is arranged on the outlet pipe of piston high-density pump, the pressurized vessel that described stable-pressure device is a cavity, the bottom of pressurized vessel is provided with through hole, be placed with the inflating rubber capsule in the inside of pressurized vessel, the top of pressurized vessel is provided with the top cover that picks and places the inflating rubber capsule.
The beneficial effects of the utility model are: simple in structure, and low cost of manufacture; Easy for installation, only need on pipeline, install a threeway and reducer fitting additional; The inflation rubber capsule can be adjusted targetedly for different pressure; By production practices, prove that device of the present utility model is simply effective, easy to use, obtained significant economic benefit and social benefit.
The accompanying drawing explanation:
Fig. 1 is the section of structure of the stable-pressure device for piston high-density pump of prior art.
Fig. 2 is the section of structure of the stable-pressure device for piston high-density pump of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
The working principle of piston high-density pump of the present utility model is identical with prior art, can be with reference to prior art, so no longer narration, the utility model and the difference of prior art are that the structure of stable-pressure device is different, below are described in detail:
As shown in Figure 2, stable-pressure device for piston high-density pump of the present utility model, described stable-pressure device is arranged on the outlet pipe 4 of piston high-density pump 2, the pressurized vessel 13 that described stable-pressure device is a cavity, the bottom of pressurized vessel 13 is provided with through hole 15, be placed with inflating rubber capsule 14 in the inside of pressurized vessel 13, the top of pressurized vessel 13 is provided with the top cover 17 that picks and places inflating rubber capsule 14.
Be provided with through hole 15 in the bottom of pressurized vessel 13, the through hole 15 of pressurized vessel is connected on outlet pipe 4 by three-way pipe.1 is intake pipe.
Described inflating rubber capsule 14 is the enclosed high pressure capsule, and the capsule requirement of withstand voltage is greater than maximum pump pressure, is provided with valve cock 16 on inflating rubber capsule 14.
Stable-pressure device of the present utility model is installed on the output pipe of water pump, and the pressure pulsation liquid effects that the pump housing produces is on aerated capsule, and the compression property of application gas is subdued crest and the trough with compensatory pressure pulsation liquid, realizes the stable of pressure.
Above-described embodiment is only for illustrating technological thought of the present utility model and characteristics, its purpose is to make those skilled in the art can understand content of the present utility model and implement according to this, can not only with the present embodiment, limit the scope of the claims of the present utility model, be equal variation or the modification that spirit that all the utility model disclose is done, still drop in the scope of the claims of the present utility model.
