Description

Technical Field

[0001] The utility model relates to the technical field of diaphragm pumps, in particular to a water-cooling pump casing and a water pump having the pump casing. Background Art

[0002] A diaphragm pump is a positive displacement pump that uses a diaphragm to separate the fluid being pumped from the piston, using the diaphragm's movement to draw in and out the fluid. The diaphragm divides the inner cavity of the housing into a volume chamber and a piston chamber. Diaphragm pumps are primarily categorized as plunger diaphragm pumps, hydraulic diaphragm pumps, and pneumatic diaphragm pumps. Regardless of the type of diaphragm pump, the diaphragm is a critical component, and parameters such as the diaphragm's travel and lifespan affect the pump's performance. In a plunger diaphragm pump, the piston moves the diaphragm up and down. The downward movement of the piston pulls on the diaphragm, increasing the volume of the volume chamber and thereby drawing in fluid. The upward movement of the piston pushes on the diaphragm, reducing the volume of the volume chamber and thereby pressurizing and discharging the drawn-in fluid. During operation, a diaphragm pump generates heat, primarily from two sources: heat generated by the rotation of the eccentric shaft at the pump's center and frictional heat generated between the piston and the cylinder wall. When the outlet pressure of the diaphragm pump is less than or equal to 4MPa, the self-generated heat temperature of the diaphragm pump is about 50-60℃. The normal operating temperature of the diaphragm pump can be guaranteed by natural cooling to avoid overheating. When the outlet pressure of the diaphragm pump is greater than or equal to 5MPa, the self-generated heat temperature of the diaphragm pump is greater than 100℃, or even as high as 200℃. At this time, additional cooling equipment is required to cool the diaphragm pump to avoid overheating. The diaphragm pump in the existing technology is a large-volume and high-power diaphragm pump with a flow rate of up to 30m 3 / h, and the weight can reach 3 to 4 tons. This diaphragm pump has a large oil tank and a large heat dissipation area. It can meet the operating temperature requirements by relying on its own natural heat dissipation. There is also a small diaphragm pump with a flow rate of about 10m 3 / h, weighing about 1 ton, this type of diaphragm pump has a low flow rate and low power, and can meet the operating temperature requirements without cooling.

[0003] However, small but high-powered diaphragm pumps lack good natural heat dissipation conditions and require additional cooling components to cool them down to meet operating temperature requirements. However, these additional cooling components increase the diaphragm pump's piping, increase the pump's cost, and take up more space. In view of this, the present invention provides a water-cooled pump casing and a water pump having the same, which eliminate the need for additional cooling equipment and do not occupy additional space, making it more suitable for heat dissipation in small, high-powered diaphragm pumps.
