Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] see Figure 1-2 , the present invention provides a technical solution: a silent type split double suction pump, including a base 1, the bottom surface of the base 1 is fixedly connected with a shock absorbing pad 2, and the horizontal length of the shock absorbing pad 2 is the same as the horizontal length of the base 1 The values ​​are equal, which can effectively isolate the external vibration from being transmitted to the device, so as to generate re...

Abstract

The invention discloses a silent type middle opening double-suction pump. The silent type middle opening double-suction pump comprises a base, wherein two symmetric chutes are formed in the upper surface of the base, and two symmetric sliding blocks are clamped into each chute; two symmetric damping boxes are fixedly connected to the upper surface of the base, and the two damping boxes are correspondingly positioned right above the two chutes; an inverted U shaped damping steel plates are arranged in each damping box; the upper surfaces of the two sliding blocks are fixedly connected to the bottom surfaces of the damping steel plates; and a through hole is formed in the middle part of the upper surface of each damping box. According to the silent type middle opening double-suction pump, springs and the damping steel plates are arranged and are capable of fully absorbing vibration produced by the middle opening double-suction pump body, and thus the noise produced by the vibrating of the middle opening double-suction pump body can be effectively avoided; sound absorbing cotton is provided, so that the noise produced in the middle opening double-suction pump body can be sealed into anoise enclosure, and as a result, the noise produced in the middle opening double-suction pump body can be effectively prevented from transmitting to the outer part.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to a silent split split double-suction pump. Background technique [0002] As an important form of centrifugal pump, double-suction pump is widely used in engineering because of its high lift and large flow rate. The impeller of this pump type is actually composed of two back-to-back impellers. From the impeller The outflowing water flows into a volute, because the water enters from both sides of the impeller, and the casing is divided into upper and lower halves from the center line of the shaft, so it is called a split double suction pump. [0003] In the water pump industry, split double-suction pumps are products with a large variety and a wide range of products, with good performance and convenient maintenance. The nature of the liquid is similar to that of clear water. The existing split double suction pump will cause double suction due to the unbalanced internal magnetic...
