Description

Изобретение относитс к насосостроению и может быть использовано в лабиринтных насосах.The invention relates to pump engineering and can be used in labyrinth pumps.

Известен лабиринтный насос, содержащий корпус и расположенную в нем неподвижную втулку, в которой установлен с рабочим зазором относит&пьно нее вращающийс винт, имеющий переднюю опору, причем втулка и винт выполнеш с многозаходными винтовыми нарезками противоположного направлени 13.A labyrinth pump is known, comprising a housing and a fixed sleeve located therein, in which a rotating screw having a front support is installed with a working clearance, and the sleeve and the screw are made with multiple-thread screw cuts of the opposite direction 13.

Недостатком известного насоса вл етс износ рабочих органов, наблюдаемый при попадании в рабочий зазор по. сторонних включений, размер которых больше величины рабочего зазора. В результате происходит износ элементов нэсоса, снижаетс его долговечность.The disadvantage of the known pump is the wear of the working bodies, which is observed when it enters the working gap. third-party inclusions, the size of which is greater than the size of the working gap. As a result, the elements of Nassos are worn out, its durability is reduced.

Цель изобретени - увеличение срока службы насоса.The purpose of the invention is to increase the service life of the pump.

Указанна цель достигаетс тем, чтов корпусе со стороны входа установ- лен со сквозными концентричными прорез ми , а на торце винта закреплены кольца, расположенные в прорез х диска с зазорами, меньшими рабочего зазора, причем передн опора выпол- нена в виде цапфы и обоймы, закрепленных соответсвенно на винте и диске и расположенных относительно друг друга с зазором, меньшим рабочего зазора.This goal is achieved by the fact that the casing is mounted on the inlet side with through concentric cuts, and on the screw end there are rings located in the cuts of the disc with gaps smaller than the working clearance, with the front bearing in the form of a pin and a clip fixed respectively on the screw and disk and located relative to each other with a gap smaller than the working gap.

На фиг. 1 показан насос, продольный разрез; на фиг. 2 - вид А на фиг. 1.FIG. 1 shows a pump, a longitudinal section; in fig. 2 is a view A of FIG. one.

Насос содержит корпус 1 и расположенную в нем неподвижную втулку 2, в которой с рабочим зазором 3 относительно втулки 2 установлен вращающийс винт 4, имеющий переднюю опору 5. Втулка 2 и винт 4 выполнены с многозаходньши винтовыми нарезками (не показаны ) противоположного направлени .The pump includes a housing 1 and a fixed sleeve 2 located therein, in which a rotating screw 4 having a front support 5 is installed with a working gap 3 relative to the sleeve 2. The sleeve 2 and screw 4 are made with multiple screw cuttings (not shown) of the opposite direction.

В корпусе 1 со стороны входа установлен диск 7 со сквозными концентр прорез ми 8, а на торце 9 нинчл 4 закреплены кольца 10, расположемIn case 1, on the entrance side, there is a disk 7 with through-concentrating slots 8, and on the end of 9 Ninch 4 rings 10 are fixed;

Claims

Claim

A labyrinth pump containing a housing and a stationary sleeve located in it, in which a rotating screw having a front support is mounted with a working clearance relative to it, the sleeve and screw being made with multi-thread screw threads of the opposite direction, with the aim that, in order to increase the service life, in the case from the inlet side it is installed with through concentric slots, and on the end of the screw there are fixed rings located in the slots of the disk with gaps .. smaller than the working gap, and the front The ora is made in the form of a trunnion and a holder secured respectively to a screw and a disk and located relative to each other with a gap smaller than the working gap.

external particles, which prevents wear of the pump elements, and the presence of the front support 5 prevents the contact of the sleeve 2 and screw 4, allowing them to perform much longer
