Abstract
The utility model designs an improved structure of a pump body of a seal-free self-control self-priming pump, which comprises the pump body and is characterized in that: the pump body comprises barrel, chassis, seal, and the seal welding is in the barrel bottom, and the chassis is a ring dish, is provided with a tang on the inboard upper portion of ring dish, and the tang on chassis is connected in the barrel spot welding. The utility model has the advantage that the base plate is made into a circular ring shape and a non-circular cake shape. After improvement, a sealing disc with the same thickness as the cylinder body is arranged, and the sealing disc and the cylinder body are fully welded. The chassis and the barrel are positioned through the seam allowance of the plane inner ring on the chassis, and the barrel is reinforced and connected by adopting a reinforcing rib plate in a welding mode. Meanwhile, spot welding is carried out between the chassis and the barrel. This operation has reduced welding area, avoids welding heat energy to lead to the chassis to warp, avoids full welding back chassis to lead to the water pump vibration because of warping. The mode of putty scraping and painting between the cylinder body and the chassis is adopted, so that the attractiveness is avoided.
Description
Technical Field
The utility model relates to a self-priming pump, in particular to an improved structure of a pump body of a seal-free self-control self-priming pump.
Background
The conventional non-sealing self-control self-priming pump has a simple structure and a cylindrical shape, the main structure is shown in figure 1,
in the figure 1, a cylinder 11 and a chassis 12 are directly welded to form a large space for containing liquid, the self-priming pump is not high in lift and belongs to a low-pressure container, and the wall thickness of the cylinder is generally 4-10mm according to the size of the pump. Meanwhile, the thickness of the chassis is 10-25mm according to the diameter of the cylinder body. In the structure, the chassis plays a role of sealing the lower end of the cylinder body and simultaneously plays a role of connecting the bottom feet. The chassis is connected with the cylinder body in a welding way. As the lower end enclosure, the chassis and the cylinder body must be fully welded. Experience shows that when the thickness of the chassis is not more than 16mm, the chassis deforms seriously after full welding. When the bottom foot is used for connection, the bottom surface of the chassis after full welding is not flat, the water pump is easy to vibrate, and large noise is generated.
Disclosure of Invention
The utility model aims to solve the problems of the prior art that the conventional seal-free self-control self-priming pump is cylindrical, improve the welding structure of the chassis and the barrel of the seal-free self-control self-priming pump and avoid the deformation of the chassis. Provides an improved structure of a pump body of a seal-free self-control self-priming pump. The utility model designs an improved structure of a pump body of a seal-free self-control self-priming pump, which comprises the pump body and is characterized in that: the pump body comprises barrel, chassis, seal, and the seal welding is in the barrel bottom, and the chassis is a ring dish, is provided with a tang on the inboard upper portion of ring dish, and the tang on barrel spot welding connection chassis. The upper side of the cylinder body of the pump body is provided with a water outlet, and the lower side of the cylinder body is provided with a water inlet. The middle of the cylinder body of the pump body is provided with a clapboard, the lower part of the clapboard is a suction chamber, and the upper part of the clapboard is a pump chamber. A plurality of rib plates are arranged between the bottom of the cylinder body and the chassis. The utility model has the advantage that the base plate is made into a circular ring shape and a non-circular cake shape. After improvement, a sealing disc with the same thickness as the cylinder body is arranged, and the sealing disc and the cylinder body are subjected to full welding treatment. The chassis and the cylinder are positioned through the plane inner ring seam allowance on the chassis, and the cylinder is reinforced and connected by adopting a reinforcing rib plate in a welding mode. Meanwhile, spot welding is carried out between the chassis and the barrel. This operation has reduced welding area, avoids welding heat energy to lead to the chassis to warp, avoids full welding back chassis to lead to the water pump vibration because of warping. The mode of putty scraping and painting between the cylinder body and the chassis is adopted, so that the attractiveness is avoided.

The device comprises a barrel body 1, a base plate 2, a sealing plate 3, rib plates 4, a spigot 5, a partition plate 6, a suction chamber 7, a pump chamber 8, a water inlet 9 and a water outlet 10.
Detailed Description
In the figure, an improved structure of a pump body of a seal-free self-control self-priming pump comprises the pump body and is characterized in that: the pump body comprises barrel, chassis, seal, and the seal welding is in the barrel bottom, and the chassis is a ring dish, is provided with a tang on the inboard upper portion of ring dish, and the tang on barrel spot welding connection chassis. The upper side of the cylinder body of the pump body is provided with a water outlet, and the lower side of the cylinder body is provided with a water inlet. The middle of the cylinder body of the pump body is provided with a clapboard, the lower part of the clapboard is a suction chamber, and the upper part of the clapboard is a pump chamber. A plurality of rib plates are arranged between the bottom of the cylinder body and the chassis. The utility model has the advantage that the base plate is made into a circular ring shape and a non-circular cake shape. After improvement, a sealing disc with the same thickness as the cylinder body is arranged, and the sealing disc and the cylinder body are subjected to full welding treatment. The chassis and the cylinder are positioned through the plane inner ring seam allowance on the chassis, and the cylinder is reinforced and connected by adopting a reinforcing rib plate in a welding mode. Meanwhile, spot welding is carried out between the chassis and the barrel. This operation has reduced welding area, avoids welding heat energy to lead to the chassis to warp, avoids full welding back chassis to lead to the water pump vibration because of warping. The mode of putty scraping and painting between the cylinder body and the chassis is adopted, so that the attractiveness is avoided.
