Abstract
The utility model relates to an oil submerged pump with double volute chambers. The existing oil submersible pumps are in a single volute chamber structure, oscillation and noise can be easily generated when the pumps work, and bearings and seals can be easily damaged. The utility model comprises a hydraulic motor, a pump body and a liquid conveying pipe, wherein the hydraulic motor is directly connected with the pump body. The utility model is characterized in that the pump body is in a double volute chamber structure and is provided with two symmetrical pump body discharge openings; the liquid conveying pipe is provided with two inlets and an outlet, wherein the two inlets are respectively butted with the pump body discharge openings. The utility model effectively eliminates radial force and axial force which can not be easily avoided by a pump with one volute chamber, and extends the service life of bearings and seals. The utility model lowers oscillation and noise and can run smoothly.
Description
The utility model relates to a kind of oil-immersed pump, is meant two volute casing oil-immersed pumps especially.
Existing with the oil hydraulic motor be prime mover unload the groove oil-immersed pump, can in the environment of inflammable, explosive and high pressure, use safely, and eliminated the air-resistance phenomenon of pump, but radial force and axial force that oil-immersed pump that should list volute casing structure produces when work, oil hydraulic motor can't be born or ability to bear relatively poor, thereby easily producing vibrations and noise during pump work, bearing and sealing are fragile.
The purpose of this utility model is to provide a kind of radial force and the axial force that can eliminate said pump, and working stability is safe and reliable, and two imports of indusion tube directly butt up against two volute casing oil-immersed pumps of pump housing discharge opening.
The utility model is achieved like this: a kind of pair of volute casing oil-immersed pump, comprise oil hydraulic motor, the pump housing, indusion tube and impeller, oil hydraulic motor directly is connected with the pump housing, it is characterized in that the pump housing is two volute casing structures, and two symmetrical pump housing discharge openings are arranged; Indusion tube has two imports and an outlet, and wherein two imports butt up against pump housing discharge opening respectively.
Described pair of volute casing oil-immersed pump is characterized in that having on the impeller cylindrical ringwise preoral loop and back choma.
Described pair of volute casing oil-immersed pump is characterized in that on the closed chamber outer wall of the pump housing or have equalizing orifice on back shroud of impeller.
Described pair of volute casing oil-immersed pump is characterized in that indusion tube (1) is down the hollow tube of " Y " shape for shape.
The utility model makes the pump body fluid flow symmetrical because the pump housing has adopted two volute casing structures, and two imports of indusion tube butt up against pump housing discharge opening respectively, and the radial force that acts on the impeller is cancelled each other; Impeller has then adopted the twoport ring structure, and having equalizing orifice on the back shroud of impeller or on the closed chamber outer wall of the pump housing, it is basic identical with impeller inlet place pressure that the pressure of closed chamber reduces to, thereby eliminated axial force, make the pump running steadily, prolonged the working life of bearing and sealing, reduced vibrations and noise, make the work of pump more safe and reliable, improved work efficiency.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is two volute casing horizontal cross.
Below in conjunction with accompanying drawing the utility model is further described: oil hydraulic motor 2 directly is rigidly connected with the pump housing 4, locate by sending out blue face and seam, impeller 5 be installed in oil hydraulic motor 2 spools 9 on.The pump housing 4 is two volute casing structures, and two symmetrical pump housing discharge openings 15 are arranged, and makes liquid stream symmetrically, and two symmetrical discharge openings 15 of the pump housing are connected respectively with two imports 12 of indusion tube 1.The hollow tube that indusion tube 1 is down " Y " or falls " U " shape for shape, the liquid of 1 two imports of indusion tube, 12 inputs converge the back from exporting 13 outputs.There are preoral loop 7 and back choma 8, two chomas to be circular cylinder on the impeller.The top of back choma 8, sealing 3 and the pump housing 4 constitutes closed chamber 10.On closed chamber 10 outer walls of the pump housing 4 or on back shroud of impeller 16, have an equalizing orifice 11.Pump cover 14 tops and impeller 5 inlets below are suction chamber 6.
Claims (4)
1, two volute casing oil-immersed pumps, comprise oil hydraulic motor (2), the pump housing (4), indusion tube (1) and impeller (5), oil hydraulic motor (2) directly is connected with the pump housing (4), it is characterized in that the pump housing (4) is two volute casing structures, and two symmetrical pump housing discharge openings (15) are arranged; Indusion tube (1) has two imports (12) and an outlet (13), and wherein two imports (12) butt up against pump housing discharge opening (15) respectively.
