Technical field
The present invention relates to Jet injector, specifically a kind of regulable ring-shaped Jet injector.
Background technique
Jet injector is a kind of shearing of jet and fluid machinery and mix reaction equipment that mass transfer biography energy is carried out in the turbulence diffusion effect utilized.This apparatus structure is simple, reliable operation, operation and maintenance cost are low, is particularly suitable under water, radiation and occasion such as inflammable and explosive.
According to the difference of employing nozzle arrangements, Jet injector can be divided into two kinds of central jet pump and annular jet pumps.The nozzle of central jet pump places in the middle of the suction chamber, is inhaled fluid ring around the nozzle outer end; The annular jet pump adopts ring nozzle, is inhaled fluid and encircles in the ring nozzle and pass through.In the annular jet pump, because suction passage is parallel with trunnion in the centre, be very beneficial for transporting of solid particle such as mineral, live fish, capsule, potato and onion etc.
The annular jet pump performance is subjected to the influence of several factors, and wherein the comparison of the area between trunnion and nozzle Effect on Performance is the most remarkable.Certain when the area ratio, its performance curve is basic fixed also.Along with the increase of being inhaled the flow-rate ratio between fluid and the working fluid, its pressure ratio and boost capability reduce.And in the middle of actual motion, the change of external conditions multiterminal, the annular jet pump of fixed-area ratio often can not move in more excellent operating range, even can not satisfy job requirement sometimes, and more renew the operation that pump will expend a large amount of physical resources and financial resources and influence whole system.
Summary of the invention
The purpose of the regulable ring-shaped Jet injector of the present invention is to provide a kind of area than adjustable annular jet pump, when operating mode changes, can compare to adapt to need of work by regulating its area, thereby make the annular jet pump always move in more excellent operating range.
A kind of regulable ring-shaped Jet injector, comprise that rectifier stack, mixing tube, trunnion, diffusing tube, outer pipe connect successively, described rectifier stack comprises rectifier lamp, is inhaled fluid hose and working fluid pipe, described rectifier lamp and working fluid pipe are connected, rectifier lamp one end is provided with end cap, inhaled fluid hose and pass end cap and can be with respect to the end cap axial motion, described end cap outer end is provided with scale, is describedly inhaled fluid hose and is provided with pointer.
The described axis of being inhaled fluid hose and rectifier lamp is located along the same line.
Be provided with the supporting element of being inhaled fluid hose for supporting in the other end of described rectifier lamp away from end cap, have the hole for the working fluid circulation on the supporting element.
Described joint of being inhaled fluid hose and end cap is provided with Sealing.
Described is straight tube by inhaling fluid hose.
Describedly inhaled the end that fluid hose is positioned at mixing tube and be provided with inlet nozzle.
Working principle of the present invention is as follows: inhaled the fluid hose end and form annular main jet with the mixing tube wall, working fluid nozzle ejection thus.Being inhaled fluid hose can move along the axis of pump to change the main jet size, thereby regulates the area ratio of annular Jet injector.
The advantage of the regulable ring-shaped Jet injector of the present invention is: area is than adjustable, and performance can be adjusted with operating mode; By increasing existing comparatively ripe transmission device on the market, it is steadily mobile along axis to realize being inhaled the fluid passage, and guarantees the sealing to pressurized working fluid simultaneously.The present invention is simple to operate, both can also can realize Automatic Control according to preset program by hand-guided.Simple in structure, with low cost, because the price performance height is conducive to promote the use.
