Изобретение относитс к насосостроению , касаетс объемных насосов и может найти применение в различных отрасл х народного хоз йстваThis invention relates to a pump engineering industry, relates to positive displacement pumps, and can be used in various industries of the national economy.
Известны объемные насосы, содержащие поршень и цилиндр, между уплотнительными цилиндрическими поверност ми которых установлено с возможностью перекатывани эластичное кольцо круглого поперечного сечени ||1Д.Volumetric pumps are known that contain a piston and a cylinder, between which cylindrical sealing surfaces are installed with the possibility of rolling an elastic ring of circular cross section || 1Д.
Недостатком известного насоса вл етс возможность проскальзывани и перекоса кольца и недостаточна степень уплотнени . Все это -снижает герметичность и надежность уплотнени .A disadvantage of the known pump is the possibility of slippage and skew of the ring and an insufficient degree of compaction. All this reduces the tightness and reliability of the seal.
Цель изобретени - повьаиение герметичности и надежности уплотнени .The purpose of the invention is to improve the tightness and reliability of the seal.
Указанна цель достигаетс тем, что на уплотнительных поверхност х поршц и цилиндра нанесены насечки.This goal is achieved by notches on the sealing surfaces of the pistons and cylinder.
На фиг. 1 представлен объемный насос (пунктиром показано положение поршн в начале хода нагнетаки ) ; на фиг. 2 - уплотннтельныё поверхности поршн и цилиндра в увеличенном масштабе.FIG. 1 shows a volumetric pump (the dotted line shows the position of the piston at the beginning of the stroke of the blowers); in fig. 2 - sealing surfaces of the piston and cylinder on an enlarged scale.
Между уплотнительными поверхност ми 1 и 2 соответственно поршн Between the sealing surfaces 1 and 2, respectively, the pistons
3 и цилиндра 4 установлено с возможностью перекатывани эластичное кольцо 5 круглого поперечного сечени . На уплотнительных поверхност х 1 и 2 нанесены насечки 6 и 7.3 and cylinder 4 is mounted with the possibility of rolling the elastic ring 5 of circular cross section. Notches 6 and 7 are applied to the sealing surfaces 1 and 2.
Объемный насос работает следующим образом.Volumetric pump works as follows.
При возвратно-поступательном движении поршн 3 в цилиндре 4 кольцо 5 перекатываетс по уплотннтельным поверхност м 1 и 2. Насечки 6 и 7 преп тствуют проскальзыванию кольца 5 по поверхност м 1In the reciprocating movement of the piston 3 in the cylinder 4, the ring 5 rolls over sealing surfaces 1 and 2. Notches 6 and 7 prevent the ring 5 from sliding along surfaces 1
и 2 и, вдавлива сь в кольцо 5, повышают герметичность уплотнени . Тем CciMdM повышаетс надежность уплотнени , так как снижаетс веро тностьand 2 and, being pressed into the ring 5, increase the tightness of the seal. Meanwhile, the CciMdM increases the reliability of the seal as it reduces the likelihood
перекоса кольца 5.ring skew 5.
