Description

(54) INERTIAL PULSER

t

The invention relates to inertial pulsators that can operate as hammers for various purposes.

According to the main author. St. No. 718630, an inertial pulsator is known, containing two controlled masses installed in a housing with the possibility of relative movement in antiphase, in the central step cough one of which is placed with the possibility of relative slip the rod and plunger facing the opposite mass, and the section area of the plunger is larger than the section area rod, and the cavity of the central stepped channel between the scissors and the rod is filled with the driving medium.

The disadvantage of such a device is that during its operation only the reciprocating movement of the rod is carried out and its rotation is impossible, which reduces the functionality of the pulsator C 7.

The purpose of the invention is to extend the functionality of the inertial pulsator.

The goal is achieved by the fact that the inertial pulsator is additionally equipped with an annular chamber, wedged into the core and an annular groove and distribution channels for periodically communicating the central stepped channel of the controlled mass with the annular chamber.

In addition, the rod of the inertial pulsator is equipped with a hydraulic rotation device placed in the annular chamber.

FIG. Figure 1 shows the inertial pulser, which is the executing function of a hand hammer with irrigation of the surface treated with a hammer; in fig. 2 - inertial pulsator, which performs the functions of a perforator, a longitudinal section; in fig. 3 shows a rotary device, section A-A in FIG. 2

Claims (2)

The inertial pulsator consists (Fig. 1, 2) of the housing 1 installed therein with the possibility of relative displacement in antiphase of douh controlled masses 2 and 3. The central channel 4 of mass 3 is made stepwise and is installed with the possibility of positive sliding the rod 5 and plunger b. The diameter of the bore of the central optic channel 4 under the plunger 6 is larger than the diameter of the bore under the rod 5 and, accordingly, the area of the plunger 6 is larger than the cross section of the rod 5. The central stepped channel 4 between the plunger 6 and the rod 5 is filled with the driving medium. The anti-phase electromagnets 7 and 8 are used to drive the controlled masses 2 and 3. To return the controlled masses 2 and 3 to the initial position, there is a spring 9 located between them (Fig. 1). Distribution channels 10 and 11 are made in rod 5. Distribution channel 10 and pipeline with non-return valve 12 are used to feed central stepped channel 4 of controlled mass 3 with driving medium. Distributive channel 13, filled in controlled mass 3, annular groove 14 the rod 5 and the distribution channel 11 connect the central stepped channel 4 to the annular chamber 15. The annular chamber 15 is provided with a nozzle 16 directed to the end of the rod 5. The distribution channels 10, 11 and 13 in an inertial pulsator, the perforator functions (Fig. 2) are made in the rod 5, and the annular groove 14 is on a controlled mass 3. The central stepped channel 4 is connected to the annular chamber 15 by means of distribution channels 13 and 11 of the annular groove 14 and the nozzle 16, in which a check valve is installed 17. In the annular chamber 15, a hydraulic rotating device 18 is placed, rigidly connected to the rod 5. The inertial pulsator operates as follows. Under the action of control electromagnetic pulses, excited by electromagnets 7 and 8, controlled masses 2 and 3 move in antiphase towards each other. At the end of the movement, the controlled mass 2 strikes the plunger 6, giving it its impulse. The pressure of the driving medium in the central flow channel 4 rises. At the same time, the plunger 6, which, due to the difference in areas, had moved up to the drawing relative to the rod 5, slowed down, and the controlled mass 3 continued to move upwards, giving its impulse through the driving medium to the rod 5. The rod 5 performs a working stroke. In this case, the distribution channel 13 through the annular groove 14 is connected to the distribution channel 11 and the driven medium under pressure flows through the annular chamber 15, the nozzle 16 onto the surface to be treated. After switching off the electromagnets 7 and 8, the controlled masses 3 and 2 and the rod 5 occupy the initial position, and the lack of the driving medium in the central stepped channel 4 under the effect of the resulting vacuum is replenished through the distribution channel 10 and the pipeline with a check valve 12. If to the controlled mass 3, in contrast to the controlled mass 2, a smaller impulse is applied, the controlled mass 3 performs a smaller stroke and the connection of the distribution channels I and 13 does not occur. Thus, by changing the magnitude of the applied pulse to the controlled mass 3, it is possible to carry out surface treatment with an inertial pulsator with or without irrigation. The difference in the operation of the inertial pulsator shown in FIG. 2, 3, from the pulsator in FIG. 1 is that the drive medium coming from the central stepped channel 4 through the distribution channels 13 and AND, the annular channel 14, the nozzle 16, into the annular chamber 15, acts on the toothed surface of the tilt rotation device 18, forcing the rod 5 to rotate during its translational movement. After completing the working cycle, the check valve 17 is closed and the replenishment of the central stepped channel 4 with the drive medium is carried out through the distribution channel 10 and the pipeline with a non-return valve 12. The annular chamber located in the housing and enclosing the rod, annular groove, distribution channels for periodic communication of the central stepped channel of the priming mass with an annular chamber, in which a hydraulic rotating device can also be placed It allows you to extend the functionality of the pulsator and increase productivity when using it.
