Description
Известны устройства дл создани медленных пульсаций, предназначенные дл гидравлических испытательных машин с индивидуальным и групповым приводами, с применением регул тора, состо щего из цилиндров с поршн ми, мен ющими направление движени рабочей жидкости в клапанном распределителе. Однако в таких устройствах нет бесконтактной передачи команд.Devices for producing slow pulsations are known, designed for hydraulic testing machines with individual and group drives, using a controller consisting of cylinders with pistons that change the direction of movement of the working fluid in the valve distributor. However, in such devices there is no contactless transmission of commands.
В описываемом устройстве этот недостаток устранен тем, что дл бесконтактной передачи команд испытательным механизмам и повышени точности измерени действующих при испытании сил, управление клапапо.м, измен ющим направление двилсени рабочей жидкости, осуществлено посредством силовой св зи цилиндров регул тора с замкнутой силоизмер ющей системой.In the described device, this disadvantage is eliminated by the fact that for contactless transmission of commands to test mechanisms and to improve the measurement accuracy of forces acting during testing, valve valves, which change the direction of displacement of the working fluid, are controlled by force coupling the regulator cylinders with a closed force measuring system.
На чертеже изображено описываемое устройство (полол ение элементов устройства слева от осевых линий соответствует наименьшей нагрузке, справа - наибольшей).The drawing shows the described device (the polarization of the elements of the device to the left of the center lines corresponds to the smallest load, to the right to the greatest).
Устройство дл создани медленных пульсаций состоит из цилиндра / дл настройки наибольщей нагрузки, цилиндра 2 дл настройки наименьшей нагрузки и клапанного распределител 3.The device for creating slow pulsations consists of a cylinder / for setting the largest load, a cylinder 2 for setting the smallest load and a valve distributor 3.
Рабоча жидкость от насоса по.трубопроводу 4 подаетс в замкнутую силоизмер ющую систему. В это врем отвод 5 клапанного распределител 3, по которому происходит сброс рабочей жидкости, закрыт клапаном 6, а отвод 7 в цилиндр / закрыт поршнем 8 цилиндра /. При возрастании нагрузки поршни § и 9 опускаютс под действием давлени рабочей жидкости, поступающей из силоизмер ющей системы в цилиндры / и 2 по трубопроводам 10 и 11.The working fluid from the pump through pipeline 4 is fed into a closed force-measuring system. At this time, the outlet 5 of the valve distributor 3, through which the working fluid is discharged, is closed by valve 6, and the outlet 7 into the cylinder / is closed by the piston 8 of the cylinder /. As the load increases, the pistons § and 9 are lowered under the action of the pressure of the working fluid supplied from the force-measuring system to the cylinders / and 2 through pipelines 10 and 11.
При достижении нагрузкой наибольшего значени поршень 8 цилиндрической выточкой 12 соедин ет зоны 13 и 14 цилиндра /, благодар чему рабоча жидкость поступает из зоны 14 в надклапанное простWhen the load reaches the maximum value, the piston 8 by the cylindrical bore 12 connects the zones 13 and 14 of the cylinder /, whereby the working fluid flows from the zone 14 to the valve valve
