Description
Technical field
The invention belongs to water pump technology more particularly to a kind of water pumps with auto-irrigation function.
Background technique
Water pump is to occupy the high field of market sale rate in electronic product, and each row, does not have the family of tap water including rural area at each industry
Front yard all be can't do without with pump, the product that water pump does not have high-lighting reform, category electromechanical industries most to fall behind over twenties years.Industrial pump is normal
The product seen, it is most of be all volute type, horizontal machine panel seat, heaviness, occupy, install and be restricted, sleeping stood using loaded down with trivial details, former
Formula multistage pump pig iron casting manufacture fluid rate is low, the big consumptive material again of volume, and efficiency is low, without distortion protective device, fills without back-water valve (BWV)
Standby, often in use to fill liquid vacuum by multiple, booting waiting steam-water separation could be worked normally by vacuum of pouring water successively, be shut down
Loss of vacuum cisco unity malfunction is poured water once more again afterwards, use process consumes the plenty of time, and loaded down with trivial details.The water of the prior art
Pump will first fill water before drawing water into pump case, and the air in pump case is emptied, and the wheel rotation of such water pump drives liquid to produce
Raw centrifugal force makes the water inlet of pump generate negative pressure for draws fluid, generates positive pressure in the water outlet of pump and liquid is discharged, if water
There is air in pump, since the density of air is less than the density of liquid, impeller drives air rotation just to can not produce centrifugal force, water pump
Can not just work, it is well known that the work poured water for water pump be it is very heavy, if it is river embankment, need artificial one barrel of one barrel of ground
Water is put on into river embankment bank, then pours into pump case, if water source is that motor-pumped well or motor-pumped well mouths are small, to pump the work of water just
Trouble needs to draw water, the solution not had also at present with waterwheel to other water head sites.

The main paragraph and undergauge section of secondary connection, the main paragraph are slidably fitted in the large aperture of positioning post holes, the undergauge section sliding
Cooperation is in the small-bore of location hole and extends down into curved groove (10a) to drive plunger (11) back and forth to transport along plunger hole
Dynamic, second spring (15b) is located in positioning post holes to force positioning column (12) to move downward.
3. water pump according to claim 2, it is characterised in that: it is equipped with water one-way valve (16b) in the apopore (22),
Water feeding one-way valve (16a) is equipped in the suction hole (21).
4. water pump according to claim 2, it is characterised in that: apopore (22) passes through communicating pipe (17) and water outlet
(302) it is connected.
5. water pump according to claim 2, it is characterised in that: when apopore (22) interior pressure is lower, apopore (22)
Interior pressure acts on the active force for being not enough to overcome second spring (15b) on positioning column (12), and positioning column (12) is downwardly into
In to curved groove (10a), reciprocal control wheel (10) is driven to rotate by right spindle (1b), and then make curved groove (10a) and positioning
Column (12) matches driving plunger (11) and moves reciprocatingly in plunger hole；When apopore (22) interior pressure rise, apopore
(22) pressure in pushes overcomes the active force of second spring (15b) to move upwards on positioning column (12), and positioning column (12) is detached from
Curved groove (10a), plunger (11) stop moving back and forth.
