Abstract

The invention relates to the mining industry and is intended for the separate synchronous supply of two liquids. The purpose of the invention is to provide a stepless change in the ratio of the volumes of liquids pumped by the installation while reducing the synchronism of the supply of the plungers (P) 4 of the pumping unit. For this, the plunger pump 2 and the motor (D) 1 are placed on a common base 3. The spring-loaded P 4 are in contact with the working surface (RP) of the disk 6 fixed on the shaft D 1. On the RP of the disk 6 there are two diametrically located protrusions. The height of the protrusions increases with increasing distance from the center of the disk 6 to its periphery. On the base 3, D 1 is fastened on the support 7, with which it can be moved with the help of a screw pair (screw 8 and nut 9) along the base 3 along its guide bars 10 in the direction perpendicular to the axial lines P 4 of pump 2 in the plane their location. When D 1 is turned on, disk 6 rotates, and П 4, pressed up by springs 5 to RP, top of disk 6, reciprocate, ensuring suction and injection of liquids. The presence of two diametrically located symmetrical protrusions provides with a symmetrical arrangement of the shaft D 1 relative to P 4 the same value of their stroke and a synchronous supply of liquids in a 1: 1 ratio. When D 1 is shifted to the right or left along the bars 10 from the middle, the stroke of one of the P 4 increases while simultaneously decreasing the stroke of the other. The synchronization of the components is maintained, but the ratio of the volumes of the injected fluids varies. 3 il.

The invention relates to the mining industry, as well as to other industries that require separate synchronous supply of two liquids.

The purpose of the invention is to provide a stepless change in the ratio of the volumes of pumped liquids while maintaining the synchronism of the supply of plungers.

Figure 1 shows the installation, top view; figure 2 is the same, side view; Fig. 3 kinematic installation diagram.

The installation for injecting the fastener includes engine 1 and pump 2 placed on a common base 3. The plungers 4 of the pump 2 with the help of springs 5 are pressed against the disk 6 attached to the motor shaft 1. On the working surface of the disk there are two diametrically symmetrical protrusions which increases with distance from the center of the disk. The engine is mounted on the support 7, with which it can move with the help of a screw pair (screw 8 and nut fixed on base 9) along the guide bars 10, the pump is equipped with suction 11 and pressure 12 valves.

A unit for inducing bonding compositions works as follows.

When the engine 1 is turned on, the disk 6 rotates, and the plungers 4 of the pump 2, pressed by the springs 5 to the working surface of the disk 6, make a reciprocating motion, providing suction through the valves 11 and discharge through the valves 12. The presence of two diametrically symmetrical projections ensures synchronous the movement of the plungers and the synchronous feeding of the components of the bonding compound. If the engine is located midway between the plungers, the components are fed in a 1: 1 volume ratio. If necessary, you can change the ratio of

components, for this purpose, by means of a screw pair of screw 8 and a nut 9 fixed to the base 3, the engine 1 together with the support 7 is displaced along the guide bars 10 to the right or left of the middle. Wherein

the distance from the center of the disk to one of the plungers increases and decreases to the other, and since the height of the protrusions on the working surface of the disk increases with increasing distance from the center, the stroke of one of the plungers increases, respectively, its feed increases and the value decreases. stroke of the other plunger and its feed is reduced. Synchronization of the pump plungers at

this is preserved.
