Problems solved by technology

[0002] Pumps with double-suction impellers in the first stage have been used in production and life, while the diversion integrators on the existing integrated double-suction pumps use a single water inlet. When the rated flow of the pump is too large, if it cannot If sufficient submerged depth is ensured, cavitation may occur in the pump. Cavitation will not only affect the working parameters such as the flow rate and head of the pump, but also cause damage to the pump structure, which is seriously harmful.
Reducing the speed of the water pump can effectively solve this problem, but the speed of the water pump decreases, the volume increases, the installation space is limited, and the manufacturing cost increases

Abstract

The invention discloses a double suction pump water inlet flow guide integrator. The double suction pump water inlet flow guide integrator comprises a lower flow guide shell and an upper flow guide shell. A double suction impeller mounting cavity is formed in the lower flow guide shell, a first water inlet located in the lower side of the double suction impeller mounting cavity is formed in the lower flow guide shell, and a second water inlet located in the upper side of the double suction impeller mounting cavity is formed in the lower flow guide shell. A water cavity is formed in the upper flow guide shell, a plurality of flow guide pipelines are arranged between the lower flow guide shell and the upper flow guide shell, and the double-suction impeller mounting cavity communicates with the water cavity through the flow guide pipelines; and a water outlet communicating with the water cavity is formed in the top of the upper flow guide shell. The water inflow of each water inlet is half of the rated flow of a water pump, the necessary net positive suction head of the water pump during work can be reduced, the design range of the flow of the water pump at the same rotating speed is enlarged, the size of the water pump is reduced, and the requirement of the pump for the mounting environment is lowered.

Description

technical field [0001] The invention relates to a diversion integrator, in particular to a double-suction pump inlet diversion integrator. Background technique [0002] Pumps with double-suction impellers in the first stage have been used in production and life, while the diversion integrators on the existing integrated double-suction pumps use a single water inlet. When the rated flow of the pump is too large, if it cannot If sufficient submerged depth is ensured, cavitation may occur in the pump. Cavitation will not only affect the flow rate, head and other working parameters of the pump, but also cause damage to the pump structure, which is seriously harmful. Reducing the speed of the water pump can effectively solve this problem, but the speed of the water pump decreases, the volume increases, the installation space is limited, and the manufacturing cost increases. Therefore, it is necessary to make substantial changes to the overall structure of the current double-suct...
