Изобретение относитс к испытательной технике, в частности к испытательным стендам, и может быть использовано дл испытаний гидроцилиндров .The invention relates to testing equipment, in particular to test stands, and can be used to test hydraulic cylinders.
Цель изобретени - повышение точности измерени давлени в полост х испытуемого гидроцилиндра.The purpose of the invention is to improve the accuracy of measuring the pressure in the cavities of the test cylinder.
На чертеже приведена гидросхема предлагаемого стенда.The drawing shows the hydraulic circuit of the proposed stand.
Гидропривод стенда содержит испытуемый 1 и нагрузочньй 2 гидроцилин- дры, насос 3, распределитель 4 и нагрузочный дроссель 5. Кроме того, стенд дополнительно содержит манометры высокого 6 и низкого 7 давлени и золотники 8 с гидроуправлением, автоматически соедин ющие при реверсировании полости высокого и низкого давлени гидроцилиндров 1 и 2 с манометрами 6 и 7.The hydraulic actuator of the stand contains test 1 and load 2 hydrocylinders, pump 3, distributor 4 and load choke 5. In addition, the stand additionally contains pressure gauges of high 6 and low 7 pressure and spools 8 with hydraulic control, which automatically connect when reversing the cavity of high and low pressure of hydraulic cylinders 1 and 2 with pressure gauges 6 and 7.
Поршнева 9 и штокова 10 полости гидроцилиндра 1 соединены с распределителем 4 магистрал ми 11 и 12, а магистрал ми 13 и 14 -с распределителем давлени - золотником 8. Поршнева 9 и штокова 10 полости грщро- цилиндра 2 соединены с дросселем 5 магистрал ми 15 и 16 и далее магистралью 17 - с распределителем 4 и магистралью 18 - с баком. Золотник 8 имеет камеры управлени , соединенные радиальными и осевыми проточками с манометрами 6 высокого и 7 низкого давлени .The piston 9 and the rod 10 of the cavity of the hydraulic cylinder 1 are connected to the valve 4 by lines 11 and 12, and the lines 13 and 14 of the pressure distributor by the spool 8. The piston 9 and the rod 10 of the cavity of the cylinder 2 are connected to the throttle 5 of the lines 15 and 16 and further by line 17 - with distributor 4 and line 18 - with tank. The spool 8 has control chambers connected by radial and axial grooves to high and 7 low pressure gauges 6.
Стенд работает следующим образом.The stand works as follows.
При крайнем положении распределител 4 рабоча жидкость от насоса поступает в поршневую полость 9 гидроцилиндра 1 и одновременно по магистрали 13 - к левой торцовой полости золотника 8, права торцова полость которого св зана со штоковойAt the extreme position of the distributor 4, the working fluid from the pump enters the piston cavity 9 of the hydraulic cylinder 1 and at the same time via line 13 to the left end cavity of the spool 8, the right end cavity of which is connected with the rod
