Изобретение относитс к гидромеханизации земл ных работ в строительстве и промышленности строительных материал в частности к исследовани м и испытани м основного оборудовани гидромеханизации-землесосов .The invention relates to the hydromechanization of earthworks in the construction and building materials industry, in particular, to research and testing of the main equipment of hydromechanization-dredging pumps.
Известен стенд дл исследовани работы землесосных агрегатов, включающий зумпф, всасывающий и напорный пульпопроводы и контрольно-измерительную аппаратуру, причем на всасывающем трубопроводе смонтирован дополнительный всас, на свободном конце которого закреплен регулируемый клапан l.A stand for researching the operation of suction units, including a sump, suction and discharge slurry pipes and instrumentation equipment, is known, and an additional suction is mounted on the suction pipe, at the free end of which an adjustable valve l is fixed.
Недостатком известного стенда вл етс то, что на нем нельз имитировать погружение землесоса под уровень воды и, следовательно, исследовать вли ние глубины погружени на изменение внешних и кавитационных характе- ристик.A disadvantage of the known stand is that it cannot imitate the immersion of a suction pump under the water level and, consequently, investigate the effect of the depth of immersion on changes in the external and cavitation characteristics.
Наиболее близким техническим решением вл етс стенд дл исследовани процесса грунтозабора, включающий зумпф, всасывающий и напорный пульпопроводы и контрольно-измерительную аппаратуру 2.The closest technical solution is a stand for investigating the soil gathering process, including a sump, suction and discharge slurry lines and instrumentation equipment 2.
Недостатком .этого стенда вл етс невозможность регулировани условий всасывани , цикличность его работы, The disadvantage of this stand is that it is impossible to control the suction conditions, the cyclical nature of its operation,
отсутствие устройства, регулирующего давление в зумпфе.the absence of a device that regulates the pressure in the sump.
Цель изобретени - расширение диапзона исследовани характеристик землесосного агрегата за счет моделировани глубины его погружени , с одновременным измерением расхода грунтового насоса и консистенции пульпы при работе землесоса на замкнутом пульпопроводе.The purpose of the invention is to expand the range of studies of the characteristics of the suction unit by simulating the depth of its immersion, while simultaneously measuring the flow rate of the ground pump and the consistency of the slurry when the suction pump is operating on a closed slurry pipeline.
Это достигаетс тем, что в предлагаемом устройстве в верхней части зумпфа установлен регулирующий клапан а поворотный сосун, соединенный со всасывающим пульпроводом, укреплен в боковой стенке зумпфа. Кроме того, стенд снабжен установленными последовательно на напорном пульпопроводе индукционным расходомером и трубчатым водомером Вентури.This is achieved by the fact that, in the proposed device, a control valve is installed in the upper part of the sump and the rotary sucker connected to the suction slurry conduit is fixed in the sump side wall. In addition, the stand is equipped with an induction flow meter and a Venturi tubular flow meter installed in series on the discharge slurry pipe.
На чертеже схематично изображен предлагаемый стенд.The drawing schematically shows the proposed stand.
Стенд имеет испытываемый грунтовой насос 1, приводимый в движение от мотора-весов 2, напорный трубопровод 3 с запорной арматурой 4, герметичный зумпф 5, в стенку которого введен поворотный всас 6.The test bench has a test ground pump 1, driven by a weighing motor 2, a pressure pipeline 3 with shut-off valves 4, a sealed sump 5, into the wall of which a rotary suction 6 is inserted.
