Description

tt

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
