Abstract
The utility model discloses a high efficiency liquid ring pump, relating to liquid varactor machinery. The high efficiency liquid ring pump comprises a liquid ring pump. Impeller blades of the liquid ring pump are arc impeller blades, an angle of each arc impeller blade bending toward the rotating direction is 45 degrees, a horn-shaped inspiration window and an exhaust window which are bidirectionally relative are respectively arranged at both ends of a front distribution plate and a back distribution plate relative to an inspiration and exhaust chamber, the size of each window is in proportion to the volume of inspiration and exhaust, an initial angle of the inspiration window is 135 degrees, the eccentric distance of an impeller and a pump body is 12-18mm, and the peripheral speed of the impeller is 16.5m/s. After the utility model is improved, the pumping efficiency is improved by above 10 percent.
Description
Technical field:
The utility model relates to fluid varactor machine, flammable explosive gas is pumped in the space that particularly a kind of centrifugal force that utilizes liquid in rotation forms in pump, can be used as the liquid-ring vacuum pump of vacuum drying, vacuum filtration and force feed gas or the efficient water-ring pump that compressor uses.
Background technique:
Existing water-ring pump, be that an eccentric shaft is installed in a pump housing, wheel hub and impeller blade thereof are installed in the pump housing on the eccentric shaft, be respectively equipped with a gas distribution plate in the pump housing at wheel hub two ends, the outboard end of two gas distribution plates covers respectively and upwards leads to suction port and exhaust port in pump, this water-ring pump, because blade is that straight plate vertically or tangentially is installed on the wheel hub, to a unidirectional suction/exhousting hole should be arranged, the power of impeller blade is little during work on each distribution plate, and the efficient of dispatch gas is low.
Summary of the invention:
The purpose of this utility model provides a kind of high water-ring pump of gas efficiency of pumping simple and compact for structure.
Technical solution of the present utility model is finished as follows, it includes a water-ring pump, it is characterized in that: the impeller blade of water-ring pump is a kind of arc impeller blade, each arc impeller blade is 45 ° to the angle of sense of rotation bending, on the distribution plate of front and back, be respectively equipped with the cattle horn shape air intake window and the exhausting window of a two-way correspondence corresponding to the two ends of suction chamber, the size of each window is directly proportional with suction tolerance, the beginning angle of air intake window is 135 °, impeller and pump housing throw of eccentric are 12-18mm, and the peripheral velocity of impeller is 16.5m/s.The utility model makes and pumps the efficient raising more than 10% through above-mentioned improvement.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1; Fig. 3 is the B-B sectional view of Fig. 1.
Embodiment:
Describe in detail in conjunction with the accompanying drawings and execute example.The utility model is improvements over the prior art, it comprises a water-ring pump, be respectively equipped with intakeport 2 and relief opening 7 on the front and back side cover 1 of water-ring pump, its improvement place is that all arc impeller blades 5 evenly are installed on a water-ring pump pump housing inner eccentric shaft, each arc impeller blade is 45 ° to the angle of sense of rotation bending, on preceding distribution plate and back distribution plate 3, be respectively equipped with the cattle horn shape air intake window 8 and the cattle horn shape exhausting window 9 of a two-way correspondence corresponding to the two ends of each suction chamber, the size of each window is directly proportional with suction tolerance, the beginning angle of air intake window is 135 °, impeller and pump housing throw of eccentric are 12-18mm, and the peripheral velocity of impeller is 16.5m/s.During the impeller rotation, fluid is subjected to action of centrifugal force to form pendular ring in the pump housing, form a crescent-shaped space between impeller and the water ring, Seal cage volume between preceding half way around two impeller blades and water ring becomes greatly gradually, produces negative pressure, by the air intake window suction gas of distribution plate, at the back half way around, the Seal cage volume diminishes gradually, and gas is compressed and is discharged by the exhausting window of distribution plate, thereby plays air-breathing and scavenging action.In running, a part of water can discharge with gas, must in pump, supply water continuously, determine compression ratio and the isoparametric function relation of corner in the compressing section, adopt method of iteration, utilize card work as the derivation of equation, circumference of impeller linear velocity definite by carrying out best revised behind the verification experimental verification.
