(54) СТЕНД ДЛЯ ДИАГНОСТИРОВАНИЯ РЕГУЛИРУЕМЫХ ДВУХСЕКЦИОННЫХ НАСОСОВ(54) STAND FOR THE DIAGNOSIS OF ADJUSTABLE TWO-SECTIONAL PUMPS
1one
Изобретение относитс к испытани м гидронасосов и может быть использовано дл технической диагностики регулируемых двухсекционных насосов.The invention relates to the testing of hydraulic pumps and can be used for the technical diagnostics of adjustable two-piece pumps.
Известен стенд дл диагностировани регулируемых двухсекционных насосов, содержащий диагностируемый насос, магистрали нагнетани каждой из секций которого соединены гидравлическими каналами с полост ми регул тора мощности насоса, приводной двигатель, нагружающие элементы, преобразователи и измерительные приборы, бак с рабочей жидкостью радиатор охлаждени и фильтр 1..A stand for diagnosing adjustable two-piece pumps is known, containing a diagnosed pump, the discharge lines of each of the sections of which are connected by hydraulic channels to the cavities of the pump power regulator, drive motor, load elements, transducers and gauges, tank with working fluid cooling radiator and filter 1. .
Недостатком известного устройства вл етс взаимовли ние в п{5оцессе испытаний диагностируемой и недиагностируемой секций, а также регул тора мощности насоса, что снижает достоверность получаемых результатов.A disadvantage of the known device is the mutual interaction in the n {5 process of testing the diagnosed and undiagnosed sections, as well as the pump power controller, which reduces the reliability of the results obtained.
Цель изобретени - повышение точности диагностировани .The purpose of the invention is to improve the accuracy of diagnosis.
Указанна цель достигаетс тем, что в устройстве полости регул тора мoщнoctи гидравлически соединены между собой дополнительным каналом, а каждый из гидравлических каналов снабжен вентилем.This goal is achieved by the fact that in the device of the cavity of the power regulator and hydraulically interconnected by an additional channel, and each of the hydraulic channels is provided with a valve.
установленным между дополнительным каналом и магистралью нагнетани .installed between the additional channel and the injection line.
На чертеже представлена принципиальна схема стенда.The drawing shows a schematic diagram of the stand.
Двухсекционный насос 1 с регулируемыми секци ми 2 и 3 приводитс во вращение приводным двигателем 4. Насос снабжен регул тором 5 мощности, полос .ти 6 и 7 которого соединены гидравлическими каналами 8 и,9 с магистрал ми 10 и 11 нагнетани секций 2 и 3 насоса 1.A two-piece pump 1 with adjustable sections 2 and 3 is driven in rotation by a driving motor 4. The pump is equipped with a power regulator 5, the lanes 6 and 7 of which are connected by hydraulic channels 8 and 9 to the highways 10 and 11 of the pump sections 2 and 3 one.

Полости 6 и 7 регул тора 5 соединены между собой дополнительным каналом 12, а каждый из каналов 8 и 9 снабжен вентилем 13 и 14. СтёнД снабжен нагружающими элементами 15 и 16, преобразовател ми 17, измерительными приборами 18-21, баком 22 с рабочей жидкостью, радиатором 23 охлаждени , фильтром 24.The cavities 6 and 7 of the regulator 5 are interconnected by an additional channel 12, and each of the channels 8 and 9 is equipped with a valve 13 and 14. The wall is equipped with loading elements 15 and 16, converters 17, measuring devices 18-21, tank 22 with a working fluid , radiator 23 cooling filter 24.
При диагностировании одной из секций насоса 1 полости - и 7 регул тора 5 сообщают с напорной магистралью диагности20 руемой секции 2, дл чего перекрьшают вентиль 14 и открывают вентиль 13. Нагружающим элементом 16 нагружают диагностируемую секцию 2 и производ т замер контролируемых величин.When diagnosing one of the sections of the pump 1, the cavities - and 7 of the regulator 5 - communicate with the discharge line of the diagnosed section 2, for which the valve 14 is closed and the valve 13 is opened. With the loading element 16, the diagnosed section 2 is loaded and measured values are measured.
Аналогично провер ют другую секцию 3.Similarly, another section 3 is tested.
При применении предлагаемого устройства можно судить о техническом состо нии каждой из секций насоса без их взаимного вли ни , что повышает точность диагностированн .When using the proposed device, it is possible to judge the technical condition of each of the pump sections without interfering with them, which improves the accuracy of diagnostics.
