Description

Flange-mountable pumps

[technical field]

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]

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.

At present, the flange is a protruding part that is integrated with the inlet and outlet of the water pump. However, the protruding flange often causes great trouble during casting. 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 great problems, and the cost of stainless steel materials for non-flowing parts is also high. In addition, the orientation of the bolt mounting holes of the integral flange is fixed, and it is not easy to align when connecting with the pipeline, so the installation is inconvenient.

[Content of the invention]

The purpose of the present invention is to solve the above-mentioned deficiencies, and to provide a water pump that can be assembled with flanges. Road connections make manufacturing easier.

In order to achieve the above purpose, a water pump that can be assembled with flanges is designed, including a water pump inlet and outlet section 110 and a flange 130. One side of the water pump inlet and outlet section 110 is provided with a water inlet 111, and the other side of the water pump inlet and outlet section 110 is A water outlet 112 is provided, and the water inlet 111 and the water outlet 112 of the water pump inlet and outlet section 110 are respectively provided with a flange mounting platform 120, and the flange installation platform 120 is fixedly connected with the water pump inlet and outlet section 110. The flange 130 is installed on the flange mounting platform 120 , and the flange 130 is provided with at least two mounting holes 132 .

The flange mounting table 120 is respectively provided with at least two raised mounting table card channels 121, the mounting table card channel 121 extends from the mounting table front end 121a to the mounting table rear end 121b, and the mounting table card channel 121 An installation platform channel 122 is formed therebetween, and the flange 130 is installed on the installation platform card channel 121 through the installation platform channel 122 .

The inner diameter of the flange 130 is provided with a flange channel 131 corresponding to the channel 122 of the mounting platform, and the flange channel 131 extends from the rear end 130b of the flange to the front end 130a of the flange, and the thickness of the flange channel 131 is less than Flange 130 thickness.

The mounting holes 132 of the flange 130 are bolt holes.

Beneficial effects of the present invention:

Since the flange installation platform is fixedly connected to the water inlet and outlet of the water pump inlet and outlet section, the flange installation platform is integrated with the water inlet and outlet section of the water pump and assembled with a separate flange, so as to be connected to the pipeline. The flange can Rotate on the flange mounting table to align the bolt mounting holes, making the combined water pump easier and more convenient than before in terms of manufacture and connection with pipelines, and finally solves the problem of traditional water pump inlet and outlet sections Difficulty in casting, many defective products, and inconvenient connection with pipelines caused by the integration with the flange. For the stainless steel inlet and outlet sections, since the flange is a non-passing part, it can be made of carbon steel, thereby reducing the Material costs.

[Detailed ways]

Below in conjunction with accompanying drawing, the present invention will be further described as follows:

As shown in accompanying drawings 1 to 4, 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 both sides of the water pump inlet and outlet section 110. On the platform 120, thereby being connected with the pipeline.

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 110, so that the fluid can flow smoothly. Each flange mounting table 120 is provided with a protruding mounting table card channel 121, the mounting table The card channel 121 extends from the front end 121a of the installation platform to the rear end 121b of the installation platform, and a plurality of installation channel channels 122 are formed between the card channels 121 of the installation platform; the flange 130 has an inner diameter corresponding to the flange installation platform 120, and the flange The inner side of 130 is provided with a flange card channel 131 corresponding to the channel 122 of the mounting platform, and the flange 130 is provided with a mounting hole 132 that can be connected to the pipeline flange, and the mounting hole 132 is a bolt hole; The rear end 130b begins to extend toward the flange front end 130a (as shown in Figure 1 and Figure 2 ), but does not extend to the flange front end 130a, that is, the flange card channel thickness I is smaller than the flange thickness b.

The following describes in detail the installation of the flange 130 on the flange mounting platform 120 at the water inlet 111 and the connection of the pipeline, and the water outlet 112 is the same as the water inlet 111, so it is omitted:

As shown in accompanying drawings 3 and 4, the flange card channel 131 formed inside the flange 130 is aligned with the mounting channel 122 formed between the mounting card channels 121 on the flange mounting platform 120, so that the flange 130 flows into and out of the water pump. The section 110 moves in the direction, and the movement of the flange 130 makes the flange card channel 131 pass through the channel 122 of the installation platform and then breaks away from the channel 122 of the installation platform, and rotates so that the flange card channel 131 moves to the position of the rear end 121b of the channel 121 of the installation platform , to form an assembling state; after the flange 130 is installed, it is connected with the inlet pipeline flange F of the inlet pipeline P through bolt holes (as shown in Figure 1), and finally completes the connection with the pipeline.
