Abstract
Изобретение относитс к уплотнительной технике. Целью изобретени вл етс повышение надежности уплотнени при всасывании и нагнетании насоса путем обеспечени посто нства контакта набивки с плунжером. Уплотнение плунжера насоса содержит корпус 1, в котором установлен стакан 2 с набивкой 3, поджимаемой с помощью крышки 4 к плунжеру 5. В глухое отверстие 6 плунжера 5 запрессована вставка 7 с напр жени ми на поверхности контакта вставки и плунжера, превышающими давление нагнетани насоса. Вставка 7 имеет осевые отверсти 8, в которые вход т с зазором вытеснители 9. При всасывании, когда снаружи на плунжер 5 действует давление от набивки 3, а изнутри с поверхности контакта действуют напр жени от запрессовки, плунжер не деформируетс . 2 ил.This invention relates to a sealing technique. The aim of the invention is to increase the reliability of the seal when sucking and pumping the pump by ensuring constant contact of the packing with the plunger. The pump plunger seal includes a housing 1 in which a cup 2 with a gasket 3 is pushed against the plunger 5 by means of cover 4. Insert 7 is pressed into the blind hole 6 of plunger 5 with voltages on the contact surface of the insert and plunger exceeding the pump discharge pressure. The insert 7 has axial bores 8 in which the displacers 9 enter with a gap. When sucked, when the outside of the plunger 5 is under pressure from the gasket 3, and the inside of the contact surface is applied, the plunger does not deform. 2 Il.
