(54) ИНЕРЦИОННЫЙ ПУЛЬСАТОР(54) INERTIAL PULSER

1one

Изобретение относитс к вибрационной технике, а точнее к инерционным пульсаторам , и может быть использовано в качестве молотков различного назначени и насосов .The invention relates to vibration technology, and more specifically to inertial pulsators, and can be used as hammers for various purposes and pumps.

Известен инерционный пульсатор, содержащий корпус, установленные в нем две управл емые массы, плунжер, расположенный в осевых каналах масс и два стержн , закрепленные в корпусе с возможностью ограниченного перемещени , один из которых подпружинен и имеет ограничитель хода 1.The inertial pulsator is known, comprising a housing, two controlled masses installed in it, a plunger located in axial mass channels and two rods fixed in the housing with the possibility of limited movement, one of which is spring-loaded and has a travel stop 1.

Недостатком таких устройств вл етс соударение подвижных деталей, что снижает их надежность и долговечность.The disadvantage of such devices is the impact of moving parts, which reduces their reliability and durability.

Цель изобретени - повышение долговечности пульсатора.The purpose of the invention is to increase the durability of the pulsator.

Дл достижени этой цели инерционный пульсатор снабжен порщн ми, каждый из которых установлен в осевом канале управл емой массы между плунжером и стержнем , уплотнен относительно массы и выполнен с площадью поперечного сечени меньшей площади поперечного сечени стержн , котора равна площади поперечного сечени плунжера.To achieve this goal, the inertial pulsator is provided with guns, each of which is installed in the axial channel of the controlled mass between the plunger and the rod, sealed relative to the mass and made with a cross-sectional area of a smaller cross-sectional area of the rod, which is equal to the cross-sectional area of the plunger.

На чертеже представлен инерционный пульсатор, .выполн ющий функции электромагнитного молотка.The drawing shows an inertial pulsator, which functions as an electromagnetic hammer.

Пульсатор содержит корпус 1 с электро- магнитом 2, внутри которого размещеныThe pulsator includes a housing 1 with an electromagnet 2, inside of which are placed

5 две управл емые массы 3 и 4. В осевом канале массы 3 установлены стержень (рабочий орган 5), с противоположной стороны-плунжер 6 и между ними - поршень 7, который уплотнен относительно массы 3. Поршень 7 раздел ет канал массы 3 на 5 two controlled masses 3 and 4. In the axial channel of the mass 3 there is a rod (working unit 5), on the opposite side there is a plunger 6 and between them there is a piston 7, which is sealed relative to the mass 3. The piston 7 separates the mass channel 3 by

10 две полости 8 и 9, заполненные приводной средой. Площадь поперечного сечени поршн 7 меньше площади поперечного сечени плунжера 6, котора в свою очередь равна площади поперечного сечени стержн 5,10 two cavities 8 and 9, filled with a driving medium. The cross sectional area of the piston 7 is smaller than the cross sectional area of the plunger 6, which in turn is equal to the cross sectional area of the rod 5,

15 вход щего в массу 3. Масса 4 также имеет осевой канал, в который со стороны, обращенной к массе 3, вставлены плунжер 6, а с противоположной стороны - стержень 10, имеющий на конце, вход щем в массу 4,15 entering the mass 3. The mass 4 also has an axial channel into which, from the side facing the mass 3, the plunger 6 is inserted, and from the opposite side, the rod 10 having at the end entering the mass 4,

Claims

20 limiter 11 stroke. The other end of the rod 10 is fixed in the housing 1 with the possibility of limited movement and compressed by the spring 12. Between the rod 10 and the plunger 6 in the channel of the mass 4 there is a sealed piston 13 dividing the channel 3 of the mass 4 into two cavities 14 and 15. The cavities 14 and 15 are filled driving medium. The cross-sectional areas of the plunger 6 and stroke limiter 11 are equal. The cross-sectional area of the piston 13 is smaller than the cross-sectional area of the restrictor 11. To hold the masses 3 and 4 in the initial position, a spring 16 is installed between them. In the moving mass 3, the opening 17 is designed to eliminate the discharge in cavity 9 when the rod moves 5. The pulsator operates as follows in a way. When current is applied to the electromagnet 2, both masses 3 and 4 begin to move towards each other, while the plunger b remains stationary. Due to the incompressibility of the drive medium enclosed in the mass channels 3 and 4, forces 7 and 13 move towards the rods 5 and 10, respectively. When the piston 13 rests on the rod 10, and the stop 11 moves into the shoulder of mass 4 (stroke 13 and the shoulder of mass 4 to limiter 11 are equal), the pressure of the driving medium sharply increases in cavity 15 with some further movement of mass 4. The plunger 6 transmits the pressure to the cavity 8. At the same time, the piston 7 will abut the rod Biv of the cavity 8 and the pressure will also rise sharply. Thus, the kinetic energy of the masses 3 and 4 is transferred to the potential energy of the driving medium in the cavity 8. Under the action of pressure, the mixture 7 together with the rod 5 is moved by an amount due to perfect useful work. At the same time, a relatively stationary system is also subjected to movement: rod 10, piston 13 and plunger 6. Spring 12 is designed to compensate for movement of rod 10. After turning off the power of electromagnet 2, the idle run of masses 3 and 4 is carried out under the action of a return spring 16. Use of rim 7 and 13 installed between the plunger 6 and the rods 5 and 10 in the mass channels 3 and 4, filled with the driving medium, eliminates the impact of the metal parts, which leads to an increase in the durability of the pulsator. An inertial pulsator comprising a body, two controlled masses installed in it, a plunger located in axial mass channels and two rods fixed in the body with the possibility of limited movement, one of which is spring-loaded and has a travel stop, characterized in that in order to increase durability, the pulsator is equipped with pistons, each of which is installed in an axial channel of a controlled mass between the plunger and the rod, compacted relative to the mass and made with a cross-sectional area of and the cross-sectional area of the rod, which is equal to the cross-sectional area of the plunger.
