Problems solved by technology
For water pumps used to pressurize tap water, they must be sanitary, so the water pump inlet and outlet sections are generally made of stainless steel. However, stainless steel casting is relatively troublesome, so more defective products often appear in casting. Production has brought a lot of problems, and the cost of using stainless steel materials for non-flowing parts is also high
In addition, the bolt mounting holes of the integral flange are fixed in position, and it is not easy to align when connecting with the pipeline, making installation inconvenient

Embodiment Construction
[0016] Below in conjunction with accompanying drawing, the present invention will be further described as follows:
[0017] as attached figure 1 To attach Figure 4 As shown, the flange 130 is not integrated with the water pump inlet and outlet section 110, but the flange 130 is made separately, and the flange 130 is installed on the flange mounting platforms 120 on both sides of the water pump inlet and outlet section 110, so as to be connected with the pipeline connected.
[0018] In the present invention, the impeller 10 is installed in the pump body of the water pump inlet and outlet section 110, and the water pump inlet and outlet section 110 has a water inlet 111 and a water outlet 112 for fluid inlet and outlet, and the pressure formed by the rotation of the impeller 10 makes the fluid suction and discharge; method The flange mounting table 120 penetrates the water inlet 111 and the water outlet 112 to form an integral body with the water pump inlet and outlet section...

The invention relates to the technical field of installation of flanges of water pumps, in particular to a water pump capable of being assembled with flanges. The water pump comprises a water pump water inlet and outlet section (11) and the flanges (130). A water outlet (111) is arranged on one side of the water pump water inlet and outlet section (110), a water outlet (112) is arranged on the other side of the water pump water inlet and outlet section (11), flange mounting tables (120) are respectively arranged at the water inlet (111) and the water outlet (112) of the water pump water inlet and outlet section (110) and are fixedly and integrally connected with the water pump water inlet and outlet section (110), the flanges (130) are mounted on the flange mounting tables (120), and at least two mounting holes (132) are arranged on each flange (130). The water pump has the advantages that easy and convenient effects in the aspects of manufacture and pipeline connection are realized as compared with an existing water pump; problems of difficulty in casting, high quantity of defective products, inconvenience in pipeline connection and the like due to the fact that the traditional water pump is integrated with flanges are solved; and because the flanges are not flow passing components and can be made carbon steel, cost is lowered.
Description
[technical field] [0001] The invention relates to the technical field of flange installation of water pumps, in particular to a water pump capable of assembling flanges. [Background technique] [0002] A water pump is a machine that uses pressure to transport fluids such as liquids and gases to the terminal. According to the driving mode, it can be divided into various types of water pumps such as circulating pumps, centrifugal pumps, axial flow pumps, and friction pumps. The water pump with small structure is used in various fields with high efficiency. The water pump with water inlet and outlet is equipped with an impeller inside the water inlet and outlet section, and the impeller uses rotation to transport fluid. The liquid transported from the inlet and outlet of the water pump inlet and outlet section needs to be connected to the pipeline. In order to connect the pipeline, it is necessary to have a flange connected to the pipeline. [0003] At present, the flange is a...
