Description
ром 10 ее углового положени . Дл ограничени обратного хода толкателей 4 служит передвижной упор 11.rum 10 its angular position. To limit the return stroke of the pushers 4, a movable stop 11 serves.
При вращении ротора 8 ролики 7 последовательно нажимают на толкатели 4, заставл их перемещатьс в направлении насосной трубки 2. Ребрами 6 башмаков 5 толкатели 4 последовательно пережимают насосную трубку 2, создава в ней перистальтическую волну и перемеща перекачиваемую среду к потребителю. Перемещением упора 11 ограничивают обратный ход толкателей 4 и, тем самым, регулируют объемную подачу насоса.When the rotor 8 rotates, the rollers 7 successively press the pushers 4, causing them to move in the direction of the pump tube 2. With the ribs 6 of the shoes 5, the pushers 4 successively press the pump tube 2, creating a peristaltic wave in it and moving the pumped medium to the consumer. The movement of the stop 11 limit the reverse motion of the pushers 4 and, thereby, regulate the volumetric flow of the pump.
Насосна трубка 2 пережимаетс каждым толкателем 4 не по всей торцовой поверхности бащмака 5, а лищь по ребру 6. В месте контакта ребра 6 с трубкой 2 происходит накопление усталостных повреждений . Периодически по мере .накоплени усталвстныз повреждений в трубке 2, корпусную деталь 3 поварачивают на некоторый угол, не равный и не кратный угловому щагу ,fо 1Йателей 4. После поворота кор . пусную детал 3 фиксируют в новом угловом положении-- фиксатором 10. При этОм происходит угловое смещение линии контакта ребер 6 толкателей 4 с трубкой 2. Последн пережимаетс в новых сечени х, в которых ранее не действовали чрезмерные напр жени и не возникало накопление усталостных повреждений. В тех же сечени х , в которых произошло накопление до некоторого заданного уровн усталостных повреждений, деформаци и износ практически прекращаютс . Это предохран ет насосную трубку 2 от преждевременных локальных разрушений, обуславливает ее равномерный износ по всей длине и увеличивает срок службы. Таким образом, за счет выполнени наThe pump tube 2 is clamped by each pusher 4 not across the entire end surface of the base 5, but across the rib 6. At the point of contact of the rib 6 with the tube 2, an accumulation of fatigue damage occurs. Periodically, as fatigue of damage in the tube 2 accumulates, the body part 3 is rotated at a certain angle that is not equal and not multiple to the angle bar, after the turn 4. After turning the box. The trigger part 3 is fixed in a new angular position — a latch 10. At this, an angular displacement of the line of contact of the ribs 6 of the pushers 4 with the tube 2 occurs. The latter is clamped in new sections in which previously no excessive stresses or accumulation of fatigue damage occurred. In the same cross sections in which up to some predetermined level of fatigue damage has accumulated, the deformation and wear are practically stopped. This protects the pump tube 2 from premature local damage, causes it to wear evenly over its entire length and increases its service life. Thus, by performing on
торце толкателей 4 поперечных ребер 6 и установки корпусной детали 3 с возможностью углового перемещени и фиксации, обеспечиваетс распределение износа равномерно по всей длине насосной трубки 2,the end face of the pushers 4 of the transverse ribs 6 and the installation of the body part 3 with the possibility of angular movement and fixation, ensures that the wear is evenly distributed over the entire length of the pump tube 2,
устран ютс преждевременные локальные разрушени и, тем самым, повышаетс ее долговечность.premature local destruction is eliminated and, thereby, its durability is increased.
