[0025] To make the purpose, technical solutions, and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in conjunction with the drawings.
[0026] The present utility model provides a multi-stage double-suction split-case pump. Please refer toFigures 1 - 4 It includes a base 100 and a double-suction split-case pump body 200. A groove 110 is provided at the top of the base 100. A bidirectional screw 120 is rotatably connected inside the groove 110. A turntable 130 is rotatably connected to the front side wall of the base 100. One end of the bidirectional screw 120 is fixedly connected to the turntable 130. A rocker 140 is fixedly installed on the side wall of the turntable 130. A slider 150 is threadedly connected to the side wall of the bidirectional screw 120. Clamping plates 160 are symmetrically installed at the tops of the two sliders 150. A limiting frame 170 is fixedly installed at the top of the base 100. A bracket 210 is fixedly installed at the bottom of the double-suction split-case pump body 200. The bracket 210 is inserted into the limiting frame 170. The double-suction split-case pump body 200 is arranged between the two clamping plates 160. Specifically, the limiting frame 170 facilitates the installation of the bracket 210, thereby facilitating the installation of the double-suction split-case pump body 200 on the base 100. At the same time, the limiting frame 170 facilitates the left and right end limiting of the double-suction split-case pump body 200. By operating the rocker 140 to rotate the turntable 130, the bidirectional screw 120 is driven to rotate. When the bidirectional screw 120 rotates, the two sliders 150 are driven to move relative to each other along the groove 110, thereby driving the clamping plates 160 on both sides to move relatively closer or farther apart. The clamping plates 160 on both sides facilitate the clamping and positioning of the front and rear side walls of the double-suction split-case pump body 200, thereby completing the installation and fixation of the double-suction split-case pump body 200. When disassembling the double-suction split-case pump body 200, use the rocker 140 to operate the two clamping plates 160 to move away from each other in the opposite direction, and operate the double-suction split-case pump body 200 to take out the bracket 210 from the limiting frame 170.
[0027] A support frame is provided at the bottom of the base 100, and a vacuum suction cup is provided at the bottom of the support frame. Specifically, the support frame facilitates the support and positioning of the bottom of the base 100, and the device is supported and fixed by adsorbing and fixing on a plane through the vacuum suction cup.
[0028] A semi-circular groove is provided on the side wall of the clamping plate 160, and anti-slip lines are provided inside the semi-circular groove. Specifically, the semi-circular groove facilitates the close fitting of the clamping plate 160 with the side wall of the double-suction split-case pump body 200, facilitating the clamping and fixing of the double-suction split-case pump body 200, and the anti-slip lines improve the stability during clamping.
[0029] A clamping groove is provided on the inner wall of the limiting frame 170, and the bracket 210 is connected to the limiting frame 170 through the clamping groove. Specifically, the clamping groove facilitates the connection and positioning of the bracket 210 with the limiting frame 170, thereby limiting the double-suction split-case pump body 200.
[0030] The bottom of the clamping plate 160 is slidably connected to the top of the base 100. Specifically, it facilitates the stable movement of the clamping plate 160 and is convenient for clamping and fixing.
[0031] The side wall of the rocker 140 is provided with anti-slip lines. Specifically, the anti-slip lines facilitate increasing the anti-slip property of the rocker 140 and are convenient for personnel to operate.
[0032] Combined with Figures 1 - 4 , a multi-stage double-suction split-case pump in this embodiment is used as follows: During the installation and fixation of the multi-stage double-suction split-case pump, the bracket 210 at the bottom of the double-suction split-case pump body 200 is inserted into the limit frame 170, so as to install the double-suction split-case pump body 200 on the base 100. At the same time, the left and right ends of the double-suction split-case pump body 200 are limited by the limit frame 170. The rocker 140 is used to operate the turntable 130 to rotate, thereby driving the bidirectional screw 120 to rotate. When the bidirectional screw 120 rotates, it drives the two sliders 150 to move relative to each other along the groove 110, thereby driving the clamping plates 160 on both sides to approach relatively. The clamping plates 160 on both sides are used to clamp and position the front and rear side walls of the double-suction split-case pump body 200, so as to complete the installation and fixation of the double-suction split-case pump body 200, which is convenient for connecting and fixing the pump body to the base 100, and has good stability. When disassembling the double-suction split-case pump body 200, the rocker 140 is used to operate the two clamping plates 160 to move away from each other in the opposite direction, so that the clamping force on both sides of the double-suction split-case pump body 200 is lost. Just operate the double-suction split-case pump body 200 to take out the bracket 210 upward from the limit frame 170. The operation process is relatively simple, convenient for installation or disassembly, and improves work efficiency.
