High-absorption process energy-saving device of pneumatic diaphragm pump

Abstract

The invention discloses a high-absorption process energy-saving device of a pneumatic diaphragm pump. The device comprises the diaphragm pump, wherein an inlet and an outlet are formed on the diaphragm pump; the diaphragm pump is connected with an air inlet pipe; the air inlet pipe is communicated with an air source input pipeline and is then connected with the air inlet of the diaphragm pump after sequentially passing through a manual ball valve, an air filtering and pressure regulating valve and a leakage ball valve; a first pipeline is connected to the inlet; the other opening of the first pipeline is vertical downwards and is connected with a first end of a tee joint; a second end of the tee joint is communicated with the air source input pipeline through an air pipe; the manual ball valve and the air filtering and pressure regulating valve are arranged on the air pipe; a third end of the tee joint is connected to a second pipeline which is vertical downwards; and a bottom valve is arranged on the second pipeline. The absorption process can be improved by 20m; and the diaphragm pump is more convenient to use, saves energy and improves benefit.

Description

technical field [0001] The invention relates to a high-suction energy-saving device for a pneumatic diaphragm pump. Background technique [0002] A pump is a machine that transports liquids or increases the pressure of liquids. Pneumatic diaphragm pump is to transfer the air pressure energy to the liquid to increase the energy of the liquid. It is mainly used to transport water, oil, chemical solvents, corrosive liquids, liquids with particles and highly toxic liquids. But there are also deficiencies, such as the problem of suction. The maximum dry suction lift is 5.48 meters, and the maximum wet suction lift is 7.6 meters. However, under actual working conditions, such a suction distance cannot be used. For example, if the vertical suction distance is 20 meters, the pump cannot lift the liquid to more than 20 meters. On the deck of the 10,000-ton ship in Dongfang Shipyard, the water at the bottom of the warehouse must be sucked clean, but the existing diaphragm pump cann...
