Изобретение относитс к насосостроению , а именно к осевым насосам, предназначенным j9iK перекачивани неоднородных в зких масс, например жидкого навоза.The invention relates to a pump manufacturing industry, namely to axial pumps designed for pumping non-uniform viscous masses, for example, liquid manure.
Известен шнековый насос дл перекачивани жидкого навоза, содержащий корпус с установленными в нем основным и предвключенным шнеками, последний из которых выполнен с менбшим шагом витков 1.A screw pump for pumping slurry is known, comprising a casing with main and upstream screws mounted therein, the latter of which is performed with a shallow pitch of 1.
Недостатками известного насоса вл ютс мала производительность, уменьшение напора из-за закручивани жидкости основным и предвключенным шнеками в одном направлении и плохое измельчение примесей.The disadvantages of the known pump are low productivity, a decrease in the pressure due to the main and upstream screw tightening in one direction and poor grinding of impurities.
Цель изобретени - повышение производительности и напора и улучшение измельчени примесей. .The purpose of the invention is to increase productivity and pressure and improve the grinding of impurities. .
Указанна цель достигаетс тем, что шнеки имеют противоположные направлени витков и установлены с возможностью встречного вращени .This goal is achieved by the fact that the screws have opposite turns and are installed with the possibility of counter-rotation.
Причем шнеки со сторон обращенных друг к другу поверхностей снабжены торцовыми зубь ми.Moreover, the augers on the sides of the surfaces facing each other are provided with end teeth.
На чертеже изображен шнековый на- сое, продольный разрез.The drawing shows a screw bore, longitudinal section.
Насос содержит корпус 1 и установленные в нем основной 2 и предвключенный 3 шнеки соответственно. Планетарный механизм 4 обеспечивает возможность встречного вращени шнеков . Со стороны обргиценных друг к другу поверхностей шнеки снабжены торцовыми зубь ми 5. Шнек 2 установлен на валу б, а шнек 3 - на валу 7. The pump includes a housing 1 and installed in it the main 2 and the upstream 3 screws, respectively. The planetary mechanism 4 provides the possibility of counter-rotation of the screws. On the side of the surfaces which are accredited to each other, the screws are provided with end teeth 5. Screw 2 is mounted on shaft b, and screw 3 is mounted on shaft 7.
10 шнек 3 выполнен с шагом Ц витков,меньшим шага t шнека 2. шнеки 2 и 3 имейт противоположные направлени витков.10. The screw 3 is made with a pitch Δ of turns, smaller than the pitch t of the screw 2. The screws 2 and 3 have opposite directions of the turns.
Насос работает следующим образом.The pump works as follows.
1515
При врёицении валов 6 и 7 перекачиваема среда поднимаетс вверх сначала предвключенным шнеком 3, а затем основным шнеком 2. При этом на зубь х 5 происходит дополнитель20 ное измельчение примесей.When roll shafts 6 and 7 are installed, the pumped medium rises up first with the upstream screw 3 and then with the main screw 2. At the same time, additional impurities are crushed onto the tooth x 5.
Увеличение производительности и напора достигаетс за счет увеличени скорости потока при переходе его с предвключенного на основной The increase in productivity and head is achieved by increasing the flow rate when switching from the pre-included to the main
25 шнек.25 auger
