Abstract

The utility model relates to a pneumatic liquid conveyer which comprises a water storage tank, an air intake electromagnetic valve, an exhaust electromagnetic valve, a back valve, a closed water storage tank, a manual valve, an exhaust pipe, a liquid level detection switch and a water pipe. When the liquid level detection switch of the water storage tank senses that the water level is in a low water level, the exhaust electromagnetic valve is opened; the air intake electromagnetic valve is closed; water is supplemented from a water inlet pipe. When the water in the closed water storage tank is supplemented to a high water level and the liquid level detection switch senses full water level, the exhaust electromagnetic valve is controlled to close; the air intake electromagnetic valve is opened; air enters the closed water storage tank from the air inlet pipe for pressurizing. Water after pressurized enters the water storage tank (or a water tower) via the water pipe.

Description

Pneumatic liquid conveyer

The utility model relates to a kind of pneumatic-typed liquid conveyer, refers to a kind of characteristic of utilizing aerostatic buoyancy especially, send water (liquid) to eminence or liquid conveyer at a distance.

All be that city's population is more and more many, the corresponding increase of water consumption, especially suddenly increase especially in the rush hour water consumption, everybody draws water at the use suction pump, often causes the later person of drawing water to take out less than water, causes pump motor idle running and causes problems such as motor burns, water is a problem very much, therefore, traditional water pump is under the situation that the city water increases sharply now, and rate of fault greatly improves; And present suction pump technology can not make above-mentioned shortcoming improve.Traditional water failure of pump rate increases, main because of following shortcoming is arranged, promptly when aqua storage tank (or water tank) lack of water, Water-pumping motor begins to draw water, but as take out, so, Water-pumping motor still rotates because of must drawing water just to stop operating to draw water to a special position until the water level of water tank always less than water; Therefore when Water-pumping motor does not stop dallying, Water-pumping motor spoilage height, problems such as the normal damage of bearings of finding to have Water-pumping motor, coil burnout, and Water-pumping motor its power consumption under the idle running situation is also quite high.

The purpose of this utility model, be to provide a kind of pneumatic-typed liquid conveyer, improve traditional suction engine because of taking out the puzzlement of burning less than water, reduce equipment failure rate, and the water of carrying equal conditions carries the energy of required consumption far below traditional water pump, when anhydrous to a certain destination with air pressure, stop to send water, the problem that does not have the empty power consumption of idle running source produces.

The purpose of this utility model is to realize like this, a kind of pneumatic-typed liquid conveyer promptly is provided, it has the sealed mode water storage tank, be connected with intake pipe on the water storage tank, outlet pipe, suction tude and steam outlet pipe, also be provided with a liquid level detecting switch in it, outlet pipe is connected to an aqua storage tank, in suction tude, be provided with an air inlet solenoid valve, in outlet pipe, be provided with an exhaust solenoid valve, opening of control circuit control air inlet solenoid valve and exhaust solenoid valve, close action, exhaust solenoid valve is opened, the air inlet closed electromagnetic valve, water enters into the sealed mode water storage tank from intake pipe; And when the water level that the liquid level detecting switch detects the sealed mode water storage tank is high water level, exhaust solenoid valve is closed, and the air inlet solenoid valve is opened, and suction tude enters forced air, sends water to aqua storage tank through waste pipe after making the water storage tank pressurization.

Pneumatic-typed liquid conveyer of the present utility model can reduce power consumption, increases economic efficiency, and its uses the mode of pneumatic conveying liquid, transmits corrosion so can improve industry, the damage that minimizing liquid causes pump or motor, the cost of reduction conveying equipment.
