Water taking device assisted by vacuum pump and water taking method

Abstract

The invention relates to the field of water delivery and discloses a water taking device assisted by a vacuum pump and a water taking method. The water taking device comprises a water pipe, one end ofthe water pipe is set as a water inlet, the other end of the water pipe is set as a water outlet, the water pipe is wave-shaped, first regulating valves are mounted at the water inlet and the water outlet, the vacuum pump which is used for vacuumizing the water pipe is arranged at the wave peak position of the water pipe, and a water suction pump is mounted on the water pipe. By the aid of the device, water in the high position can be delivered to the low position by the water pipe, the two first regulating valves control opening and closing of the water inlet and the water outlet of the water pipe respectively, when water is pumped, the water pipe is filled with water by the water suction pump, residual air in the water pipe is sucked by the vacuum pump and exhausted into the air, the water pipe is filled rapidly by the water suction pump, the first regulating valves in the positions of the water inlet and the water outlet are opened simultaneously, high position water delivery is realized, during the delivery, the vacuum pump can pump at irregular intervals, and the vacuum pump is closed when water goes out; the water suction pump is closed when filled with water, and power is saved.

Description

technical field [0001] The invention relates to the field of water delivery, in particular to a vacuum pump-assisted water intake device and a water intake method. Background technique [0002] Common water intake devices include three types: pump water intake, artesian water intake, and siphon water intake. Water pumps have a wide range of applications, but consume a lot of energy; self-flowing water diversion does not consume energy, but it is only suitable for diverting water from high places to low places, and the places that flow through the way must be lower than a certain height of the water inlet, which requires high terrain; Siphon water intake is also to divert water from a high place to a low place, but it can span a height of less than 10 meters and does not consume energy. However, it is troublesome to start and the operation is mostly unstable. Contents of the invention [0003] Aiming at the disadvantages of high energy consumption or small application rang...
