Abstract
The utility model relates to a pressure stabilizing tank for an impact rotary drilling system. An upper joint is arranged through the upper part of a tank body of the pressure stabilizing tank; a pressure meter is installed on the side face of the upper joint 4; an energy storing device is installed on the upper part of the upper joint; a lower joint is installed on the lower end of the tank body of the pressure stabilizing tank; a liquid discharging joint is welded on the side face of the lower joint; a lower part bent pipe is installed in the center of the lower joint; a liquid charging joint is welded on one end of the lower part bent pipe, and more than two lower part bent pipe longitudinal holes are arranged in the other end; and a cover plate is welded on the top end. By combining the energy saving device and the voltage stabilizing tank, pulse and absorption impact pressure on the system is eliminated; compared with an ordinary pressure air chamber of a current voltage stabilizing tank, the pressure stabilizing tank provided by the utility model is good in voltage stabilizing effects and small in size; and a bigger air chamber is arranged in the lower part of the voltage stabilizing tank, so after entering the bigger air chamber, the high-pressure liquid is compressed and forms an air layer with bigger density on the upper part of the tank body, so liquid and foreign matters are prevented from entering the energy storing device, and the pressure stabilizing tank is suitable for higher pressure. All main accessories are in threaded connection with each other, so the pressure stabilizing tank is convenient to disassemble and easy to maintain.
Description
Technical field:
The utility model relates to a kind of drilling tools supplementary equipment, especially impact rotating and creeps into surge tank used in high-pressure duct system.
Background technique
At impact rotating, creep in high-pressure duct system, because liquid has incompressibility, slurry pump drives hydraulic impacter continuous doing work, can produce larger water hammer pressure, and itself has flow pulsation slurry pump, cause pressure duct internal fluid pressure and flowed fluctuation larger.Especially the surge pressure that water hammering produces, not only affects the service behaviour of impactor, also whole system is caused to larger infringement, makes whole high-pressure system stability decreases, and operating life significantly reduces.
Because air has good compressibility, in practical application, the inequality that surge tank reduces flow is installed between slurry pump output terminal and high-pressure rubber pipe conventionally, eliminate surge pressure, the hydraulic stability while improving work.Conventional surge tank, adopts major-diameter thick-wall seamless steel pipe conventionally, and two ends are added a cover the larger air chamber of welding formation and carried out steady pressure.Its volume, quality are all larger, poor mobility, and be generally applicable to the following low service system of 10Mpa.When being applied to high-pressure system, the stability of a system sharply declines, and the common high-pressure rubber pipe in working site swings violent, and system noise significantly increases.In principle, by increasing the volume of surge tank, can strengthen its voltage regulation result, but can cause tank diameter to increase, wall thickness increases, tank body overall weight significantly increases, and for pressure, be greater than the high-pressure system of 15Mpa, the tensile strength of common low carbon alloy steel seamless steel tube, is difficult to meet the demands, and the welding performance of high-carbon alloy steel is poor, under condition of high voltage, the bearing capacity of surge tank is difficult to guarantee.
Summary of the invention:
The purpose of this utility model is the deficiency for above-mentioned existing surge tank, and a kind of surge tank that collects accumulator and surge tank one is provided.
The purpose of this utility model is achieved through the following technical solutions:
Impact rotating creeps into system surge tank, by screw thread, upper connection 4 to be housed by surge tank tank body 7 tops, between surge tank tank body 7 tops and upper connection 4, be provided with upper sealing gasket 5, pressure gauge 1 is equipped with by pressure gauge bend pipe 2 in the side of upper connection 4, and upper connection 4 is equipped with accumulator 3 by screw thread; Lower contact 11 is equipped with by screw thread in surge tank tank body 7 lower ends, between surge tank tank body 7 lower ends and lower contact 11, be provided with lower seal circle 10, lower contact 11 sides are welded with fluid joint 12, lower bend 9 is equipped with at lower contact 11 centers, lower bend 9 one end outside surge tank tank body 7 is welded with liquid inlet joint 13, the top of lower bend 9 in surge tank tank body 7 is provided with more than two lower bend radial hole 14, and the top of lower bend 9 in surge tank tank body 7 is welded with cover plate 8 and forms.
Described pressure gauge 1 is shock-proof pressure gauge.Described accumulator 3 is diaphragm type or bladder type hydropneumatic accumulator, and the preservative treatment of nickel plating phosphorus is done in inside.
Beneficial effect: accumulator and surge tank are combined, and the pulsation of elimination system and impact-absorbing pressure, because accumulator inside is filled with high pressure nitrogen in advance, compare the air chamber of the normal pressure of traditional surge tank, and voltage regulation result is better, volume required less.Select suitable accumulator, can significantly reduce surge tank (volume own) tank body volume.Because mud has certain corrosivity, and contain certain solid phase particles, impact rotating crept in system in the past, seldom occur adopting accumulator directly as voltage stabilizing element, only clear water as the Hydraulic Impact Mechanism system of medium in application to some extent, and substantially adopt stainless steel material or internal surface preservative treatment to reduce the corrosion of clear water.The accumulator life-span is compared in fluid, significantly declines.The utility model, owing to there being larger air chamber in the surge tank tank body of bottom, after entering, highly pressurised liquid is compressed, and gas forms the larger air layer of density on tank body top, thereby prevent that liquid and impurity from entering in accumulator, make the work that accumulator can be permanent.Surge tank does not need to improve voltage regulation result by increasing tank body volume, and applicable to the system of elevated pressures.Each main accessories is substantially all for being threaded, and convenient disassembly, safeguards easily.
