The water pump can draw water at a height of 1m; how should it be installed for the best results?
Thread Content
There is one cooling circulation water pump operating at fixed frequency and one that operates at variable frequency; two pumps are needed during peak times, with a total flow rate of 200–300 cubic meters per hour. The water is drawn from a tank, and the pump inlet is located about 1 meter above the liquid surface. 1. A bottom valve is used to add water before each start-up. 2. A vacuum suction tank is installed at the inlet. 3. A vacuum pump is used to create a vacuum before each start-up. What is a reliable approach if we want to automate the starting/shifting of these pumps using a PLC? Do both the foot valve and the vacuum pump require manual operation? If a vacuum water intake tank is used, is a vacuum pump also required? Thank you!
Raising the water level at the inlet and lowering the position of the pump’s inlet may increase one-time capital investment, but it should be the most cost-effective solution
Imported vacuum water intake tanks are installed, enabling one-time drainage for lifetime self-priming. It is necessary to ensure the sealing of the inlet pipelines and the water intake tank.
