Description
Technical field
The utility model belongs to water pump technical field of auxiliary facilities, be specifically related to a kind of simple in structure, connect reliably high-efficient energy-saving centrifugal pump irrigation device easily.
Background technique
Centrifugal pump is to utilize vane rotary and make the centrifugal force of water generates carry out a kind of pump of work, due to simple in structure, be easy to manufacture, install and adjust is convenient, flow and pressure are steady, are widely used.Centrifugal pump, before turn on pump, must be full of liquid in suction sleeve and pump, and vane rotary water dumping forms vacuum, could absorb water, if there is no water in pump, in pump chamber, cannot form vacuum, also just can not draw water.After turn on pump, pump shaft impeller and water do high speed rotary motion, and under the effect of centrifugal force, water flies away from impeller and outwards penetrates, and the liquid of ejaculation speed in pump case explosion chamber is slack-off gradually, and pressure increases gradually, and then from pump discharge, discharge tube flows out.Now, around being thrown toward due to liquid, blade center forms the vacuum low-pressure district that not only there is no air but also there is no liquid, liquid in liquid pool is under the atmospheric effect of pond face, in suction pipe inflow pump, liquid is exactly so continuously from liquid pool, be pumped up and continuously flow out from discharge tube.Therefore, the centrifugal pump using for intermittent type, due to reasons such as the leakages of check valve, goes to toward anhydrous storage in pump and suction sleeve in centrifugal pump start, and the just start of not pouring water, gently cannot draw water, heavy easily cause water pump damage.
Conventional centrifugal pump needs to take off centrifugal pump outlet pipe before use, pours in down a chimney and adds water from centrifugal pump water outlet, has both existed and has got, takes on water pipe inconvenience, wastes time and energy again; For large centrifugal pump, also having increases compact submersible pump at water outlet pipe end and assist the device of pouring water, but complex structure, cost are high, and needs the consumption energy, is difficult to be suitable for for middle-size and small-size centrifugal pump.
Model utility content
The purpose of this utility model is to provide a kind of reliable high-efficient energy-saving centrifugal pump irrigation device simple in structure, easy to connect.
The purpose of this utility model is achieved in that and comprises suction sleeve, check valve, and described suction sleeve one end is filled with water intake with centrifugal pump and is communicated with, and the other end arranges check valve and stretches into basin bottom, and described suction sleeve is the water filling port higher than centrifugal pump by valve setting; Described water filling port top arranges water reservoir and is communicated with it, the filler pipe that water reservoir setting is connected with the outlet pipe of centrifugal pump and the valve that adds water, and described valve and/or the valve that adds water are electric control valve and are electrically connected with centrifugal pump control circuit.
The utility model is by arranging the water filling port higher than centrifugal pump at centrifugal pump suction sleeve, and at the water intaking end of suction sleeve, check valve is set, before centrifugal pump starts, pour water and check valve water storage by water filling port, thereby replace tradition to pour water and need to remove the connection inconvenience problem of outlet pipe from centrifugal pump water outlet.Further water filling port setting can also be to funnel-like, so that add water, or water filling port is connected with running water pipe, directly pour water by running water pipe; Convenient for the ease of what pour water, also can water reservoir be set on water filling port top, particularly large-scale water reservoir adds water in advance in water reservoir, as long as open water filling port valve need to pour water time, once adds water to realize repeatedly and pours water; Certainly, also can further filler pipe be set and the valve that adds water at water reservoir, and filler pipe is connected with centrifugal pump water outlet or outlet pipe, when centrifugal pump draws water, shunting is to water reservoir moisturizing; The valve that adds water of water filling port and filler pipe is set to electric control valve, and liquid-level switch is set in water reservoir, valve and the liquid-level switch of water filling port and filler pipe are connected with centrifugal pump control circuit, can be by control circuit auto-irrigation and moisturizing while drawing water, too low cannot the pouring water of liquid level reported to the police, and realizes the automatic control of whole device.The utility model is simple in structure, easy to connect reliable.
