Недостатком устройства вл етс повышенна скорость соудар юшихс масс, что снижает долговечность работы.The disadvantage of the device is the increased speed of the impact of the masses, which reduces the durability of the work.

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

Поставленна цель достигаетс тем, что стержень второй массы закреплен в корпусе с возможностью ограниченного перемещени , снабжен пружиной и ограничителем хода . При этом плунжер выполнен в виде двух соосно расположенных отдельных частей.The goal is achieved by the fact that the rod of the second mass is fixed in the housing with the possibility of limited movement, equipped with a spring and a travel stop. In this case, the plunger is made in the form of two coaxially arranged separate parts.

Инерционный пульсатор содержит две управл емые массы 1 и 2 с осевыми ступенчатыми каналами 3 и 4, в которых размещены стержни 5 и 6 закрепленные в корпусе 7. Между стержн ми 5 л 6 расположен плунжер 8. Стержень 6 управл емой массы 2 снабжен пружиной 9 и ограничителем 10 хода . Плунжер выполнен в виде двух соосно 10 расположенных- частей 8 и П. Между управл емыми масссами 1 и 2 расположена пружина 12.Inertial pulsator contains two controlled masses 1 and 2 with axial stepped channels 3 and 4, in which rods 5 and 6 are mounted fixed in housing 7. Plunger 8 is located between rods 5 and 6. Rod 6 of controlled mass 2 is equipped with a spring 9 and limiter 10 stroke. The plunger is made in the form of two coaxially 10 spaced parts 8 and P. A spring 12 is located between the controlled masses 1 and 2.

Ка15 налы 3 и 4 соответственно между плунжерами 8 и 11 и стержн ми 5 и 6 заполнены рабочей жидкостью. Привод инерционного пульсатора выполнен в виде двух электромагнитов 15 и 16.In the rod 5 of the inertial pulsator (Fig. 1), channels are made for the discharge 13 and the suction 14 of the working fluid. Cables 3 and 4, respectively, between the plungers 8 and 11 and the rods 5 and 6 are filled with the working fluid. The drive of the inertial pulsator is made in the form of two electromagnets 15 and 16.

Claims

20 (Fig. 2), performing the function of a shock vibrator, are hydraulic pulses received from a pulsator of any design. At the same time, chambers 17 and 18 are formed to move the controlled masses 1 and 2, and the percussion instrument 19 is fixed in the housing 7 through the shock absorber 20. The inertial pulsator works as follows. When current is applied to the power windings of electromagnets 15 and 16, both controlled masses 1 and 2 begin to move towards each other. At that, the plunger 8 starts moving downwards relative to the controlled mass 1, and the plunger 11 starts moving upwards relative to the controlled mass 2, but all the time the plungers 8 and 11 remain extended from the masses. As a result of movement under the action of electromagnetic pulses of controlled masses 1 and 2 towards each other, the plungers 8 and 11 also move towards each other, but with slower speeds than the controlled masses. The stroke of the controlled mass 2 relative to the rod 6 to the limiter 10 is equal to the motion of the controlled mass 2 before the impact with the plunger 8. When the plunger 8 and 11 collide, the limiter 10 of the stroke abuts the end surface of the channel 4 of the controlled mass

2. Since the rod 6 stops its movement relative to the controlled mass 2, the plunger 11 also stops its movement relative to the controlled mass 2 due to the incompressibility of the working fluid filled in the channel 4. At the same time, the system controlled mass 2 is the rod b and the plunger 11 begins to move after impact on the stroke, which is caused by the change in volume in channel 3 due to the performance of useful work. Before striking, the power supply to the electromagnets 15 and 16 is turned off and the idling of the masses is carried out under the action of the spring 12. The process is then repeated. Shock vibration hammer (Fig. 2) works in a similar way. The difference lies in the fact that both controlled masses 1 and 2 move towards each other under the action of hydraulic impulses supplied simultaneously to chambers 17 and 18. Thus, due to placement of rod b in body 7 with limited movement and the two coaxially arranged parts 8 and 9 decrease the speed of the colliding masses, which increases the durability of the inertial pulsator. Claims of Invention An inertial pulsator containing two controllable masses, in the axial stepped channels of which the rods fixed in the housing, as well as the plunger, are mounted. located between them, characterized in that, in order to increase durability, the rod of the second mass is fixed in the housing with the possibility of limited movement, provided with a spring and a travel stop, while the plunger is made in the form of two coaxially arranged parts.
