Description

Pneumatic Diaphragm Pump High Suction Energy Saving Device

technical field

The utility model relates to a high-suction energy-saving device for a pneumatic diaphragm pump.

Background technique

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 cannot reach this level.

Detailed ways

    The utility model will be further described below according to the accompanying drawings and specific embodiments:

As shown in Figure 1, a pneumatic diaphragm pump high-suction energy-saving device includes a diaphragm pump 1, which is provided with an inlet 2, an outlet 3, and is connected with an air inlet pipe 4, and the air inlet pipe 4 is connected to an air source input The pipelines are connected and connected to the air inlet of the diaphragm pump 1 through a manual ball valve 7, air filter pressure regulating valve 6 and leakage ball valve 5 in sequence, and a first pipeline 12 is connected to the inlet 2. The first pipeline The other opening of 12 is vertically downward and connected to the first end of a tee 8, the second end of the tee 8 communicates with the air source input pipeline through an air pipe 9, and the air pipe 9 is provided with a manual ball valve 7 And an air filter pressure regulating valve 6, the third end of the tee 8 is connected with the vertically downward second pipeline 13, and the bottom valve 10 is arranged on the second pipeline 13.

In this embodiment, a filter 11 is provided at the lower end of the second pipeline 13, and extends vertically into the water. The filter is composed of a leaking net, which can prevent debris from entering the diaphragm pump and increase the service life of the diaphragm pump. ; Bottom valve 10 is a one-way valve, so that water will not fall back when sucked in; the air source is compressed air.

When in use, open the manual ball valve 7, the air filter pressure regulating valve 6 and the leakage ball valve 5 on the intake pipe to adjust the air intake, give the diaphragm pump 1 a certain air pressure, the diaphragm pump 1 starts to work, and the water is sucked up by the diaphragm pump 1 , into the diaphragm pump 1, at this time, the suction lift of the diaphragm pump 1 can only reach about 7.6 meters, and no lower water can be sucked out; open the manual ball valve 7 and the air filter pressure regulating valve 6 on the air pipe 9 to adjust the air pressure, The air is made to enter the diaphragm pump 1 from the tee 8 through the vertical first pipeline 12 in the shape of small bubbles.
