Description

Technical Field

[0001] The utility model relates to the technical field of multi-stage pump accessories, and specifically relates to a horizontal multi-stage pump water outlet section casting. Background Technique

[0002] A multi-stage pump is a centrifugal pump in which the water inlet and outlet sections and the middle section are combined together by a pull rod. Its output water pressure can be very large. It also relies on the rotation of the impeller to obtain centrifugal force, thereby pumping materials. When the gas density reaches the working range of the mechanical vacuum pump, it is pumped out, and thus a high vacuum is gradually obtained.

[0003] A multi-stage pump realizes suction, compression, and exhaust by changing the volume of the pump cavity. Therefore, it is a centrifugal pump with variable volume.

[0004] When the existing horizontal multi-stage pump water outlet section casting is in use, for convenient connection, the casting body of the water outlet section is connected by a rotating fastening rod. During operation, it is still necessary to rotate multiple fastening rods in sequence, and the disassembly and assembly are relatively cumbersome and cannot be fastened by sequential operation. For this reason, this application proposes a horizontal multi-stage pump water outlet section casting. Content of the Utility Model

[0029] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following will further describe the implementation manners of the present utility model in conjunction with the accompanying drawings.

[0030] The present utility model provides a horizontal multi-stage pump water outlet section casting, which is connected to the lower end of the main body of the casting in the water outlet section by a connecting piece, and an adjusting piece is arranged on the main body of the casting in the water outlet section. When the adjusting piece is rotated, the connecting piece can be synchronously driven to rotate through the adjusting piece, realizing the synchronous connection of multiple connecting pieces, which is convenient for quick connection and use. Please refer to Figures 1-4 , including: the main body 100 of the casting in the water outlet section, the connecting piece 200 and the adjusting piece 300.

[0031] The main body 100 of the casting in the water outlet section, flanges are provided at both the top and the bottom of the main body 100 of the casting in the water outlet section

[0032] The connecting piece 200 is arranged at the lower end of the main body 100 of the water outlet section casting. The connecting piece 200 includes a bolt 210 and a gear 220. The bolt 210 is connected to the lower end of the main body 100 of the water outlet section casting, and the gear 220 is arranged at the upper end of the bolt 210;

[0033] Among them, the bolt 210 is connected to the flange, and the bolt 210 is driven to rotate through the gear 220.

[0034] The adjusting piece 300 is arranged outside the main body 100 of the water outlet section casting. The adjusting piece 300 includes a sliding tube 310, a sleeve 320 and internal teeth 330. The sliding tube 310 is slidably connected to the outer wall of the main body 100 of the water outlet section casting. The sleeve 320 is arranged at the lower end of the sliding tube 310, and the internal teeth 330 meshing with the gear 220 are arranged on the inner wall of the sleeve 320;

[0035] Among them, the adjusting piece 300 slides and rotates on the main body 100 of the water outlet section casting through the sliding tube 310. When the adjusting piece 300 rotates, the gear 220 is driven to rotate through the meshing of the internal teeth 330 of the sleeve 320, so as to drive the bolt 210 to rotate for connection.

[0036] Since the outer wall of the sliding tube 310 is smooth and it is difficult to rotate and operate, connection holes 340 are arranged at both ends of the sliding tube 310, and operating handles 400 are arranged on the connection holes 340, and the sliding tube 310 is rotated and operated through the operating handles 400.

[0037] Specifically, the operating handle 400 includes a handle rod 410 and a threaded connection end 420. The threaded connection end 420 screwed to the connection hole 340 is arranged at the end of the handle rod 410. The handle rod 410 is screwed to the connection hole 340 through the threaded connection end 420 and can be removed after use.

[0038] To avoid structural looseness, a locking double nut 500 is arranged on the outer wall of the main body 100 of the water outlet section casting. An external thread screwed to the locking double nut 500 is arranged on the outer wall of the main body 100 of the water outlet section casting. When the bottom of the gear 220 abuts against the flange at the lower end of the main body 100 of the water outlet section casting, the top of the inner wall of the sleeve 320 presses on the top of the gear 220, and the adjusting piece 300 is positioned by using the double nut locking principle. After positioning, the top of the inner wall of the sleeve 320 presses on the top of the gear 220 to prevent the bolt 210 from loosening.

[0039] To facilitate rotation and operation, anti-slip convex ribs are evenly distributed on the outer wall of the sliding tube 310, and the anti-slip convex ribs can be grasped for rotation and operation.

[0040] During specific use, the main body 100 of the casting in the water outlet section is connected to the horizontal multi-stage pump through a flange. The handle rod 410 is screwed onto the connection hole 340 through the threaded connection end 420. By operating the handle 400, the sliding pipe 310 is rotated. When the adjusting member 300 rotates, the internal teeth 330 of the sleeve 320 engage to drive the gear 220 to rotate, thereby driving the bolt 210 to rotate for connection. After connection, the top of the inner wall of the sleeve 320 presses on the top of the gear 220 to prevent the bolt 210 from loosening. At the same time, the adjusting member 300 is positioned using the principle of double-nut locking, and all the bolts 210 can be rotated simultaneously, facilitating quick connection and use.

[0041] Although the present utility model has been described with reference to the embodiments above, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present utility model can be combined with each other in any way. The exhaustive description of these combinations is not given in this specification only for the sake of saving space and resources. Therefore, the present utility model is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
