    one
    The invention relates to industrial transport, namely to a pump for pumping a thick mass, preferably concrete.
    A pump for pumping thick mass is known, containing two alternately operating cylinders in which there is one inlet made in the casing of the guide tube through which the transported mass pushed out of each cylinder by means of a piston enters the rotating element. The outlet is preferably located opposite the supply line to which the pumped concrete is directed. With the help of the guide tube, the cylinder, which is predominantly suction, sucks the concrete from a pre-filled container, most often attached to a casing, which is transported during the next pump stroke j.
     The use of this pump for transporting material with a high coefficient of friction is associated with difficulties attributable to significant hydrostatic forces (e.g., on the order of 20,000 kgf), which result in the deformation of pump elements that resist elastic loads, even with their considerable size. Such deformation contributes to the formation of a crack on the sliding one. relative to the other sealing elements of the guide tube. Thus, even without taking into account the inevitable abrasion of surfaces. for these reasons, leaks occur, through which a part of the liquid is lost from concrete, which leads to disruption in the working process. In addition, particles of sand penetrate into the gaps that get stuck after unloading, which occurs with each turn of the guide tube. This is a hindrance when the pump is turned on and causes significant wear on the components.
    The seals proposed to eliminate such problems include, for example, rings with grooves, axially displaceable in the return member, which are loaded and compressed under the action of
    38032
    pressure of the transported medium. However, this sand particles are stuck. The annular gap between the end of the rotary element and the ring with grooves located on it varies along the load and deformation of the device, counteracting the action of this load, and during the course
    Compression is increased by several millimeters. During activation, the guide tube begins to unload, as a result of which the load on the opposing
    15, the fixture is lowered, the gap is again compressed. On this basis, they try to reduce the elastic deformation as much as possible with the help of short traction or elements working on 20 bends.
    A pump is known for pumping thick Macqj, predominantly concrete, along a guide pipe, comprising a casing, two inlets and
    25 one exhaust, fastening respectively on the opposite walls of the casing, and mounted on the shaft of the transfer pipe, communicated on one side with the exhaust pipe and
    3Q installed with the possibility of alternate communication with the inlet pipes, the axes of which are offset relative to the axis of the rotary shaft 2j. To seal the inlet opening, a sleeve disk is placed on the corresponding inner wall of the casing, which is then influenced by considerable axial force. If the action of this axial force with the help of a rotary shaft is transferred to the casing, forces acting perpendicular to the shaft appear, which requires a certain strength, which elastically bend the shaft and together with
    .f those displacing the case and
    swivel element located in the casing. In this form of execution, when turning on the rotary element as a result of cracking
    - sticking occurs, which leads to significant wear and, therefore, reduces the reliability of the workflow.
    The purpose of the invention is to increase the reliability and service life of the pump.
    The goal is achieved by the fact that, in order to pump a thick mass, mainly concrete, in a front pipe, which contains leatherette, two inlet pipes and one outlet pipe are fixed to the opposite walls of the casing. and a shaft-mounted branch pipe communicating on one side with the outlet branch pipe and installed with the possibility of alternate communication with the inlet pipes whose axes are displaced relative to the axis of the swivel shaft to the axis of the rotary shaft more than the distance from the axis of the exhaust pipe to the axis of the transfer pipe, while the rotary shaft is mounted on two bearings, one of which is mounted in: the casing wall on the side of the exhaust pipe and is made resistant, and the other on the inside the wall of the casing from the side of the inlets. In this case, the surface of the transfer pipe in cross section on the side of the outlet pipes has a renal-like shape. S. In addition, the transfer pipe is provided with zaporny rings installed along its ends with the possibility of their movement along the axis of the corresponding pipes. The second handler can be made stubborn. In Fig. 1, a view on a & noc side view; figure 2 - section aa in figure 1; on fig.Z - section BB. Fig.4; Fig. 4 shows a section B-B in Fig. 1; on fig.Z - section GG on figure 3. The pump contains a container 1, which is preliminarily filled with a thick mass, and under which is located a casing 2, divided by a transverse edge, which is a transverse wall 3, on which is mounted a disk 4 with holes 5 and 6. The disk 4 is joined with inlets 7 and 8, located in the sleeves 9 and 10, on the ends of which there are seals 11 and which are installed in the wall 3 and in the rear wall 12. The casing 2 is closed by a cover 13. In the holes of the lip 13 there are bolts 14 that are screwed into the corresponding holes, made on flange 15 skin ha 2. On the inner side of the cover 13 there is an empty 16 with an opening 17. A sleeve 18 with seals 19 and 20 serves to hydraulically tightly connect the outlet 21, into which the concrete is transported by means of a pump. The nozzles 7 and B alternately suck the concrete from the pre-filled tank 1 through the inner space 22 of the casing 2. During the next working stroke, the cylinders alternately push the concrete through the inlets 5 and 6, made in the sleeve disc 4. Before this stroke begins, the inlets 5 or 6 communicate with the outlet 7 in the plate-16. For this purpose, the transfer pipe 23 (FIG. 3) has an inlet 24, surrounded by an axially moving ring 25, and an edge giving the inlet 24 in the cross section Mr. sectional shape of a circle. The center of gravity is in the center of the circle. In addition, the transfer nipple 23 has an unloading surface at its opposite end surrounded by an axially moving locking ring 26. This surface is bounded by an end edge 27 of the nozzle 23, which; in cross section has the shape of a kidney. Inside the kidney-shaped boundary line, the outlets partially overlap. The center of gravity of the outlet 17 is in the middle of the kidney-shaped section and is located at a radial distance RI from the geometric axis of the rotary shaft 28, while the center of gravity of the inlet holes is from the geometric axis of the shaft 28. To the radial distance R. Transfer pipe 23 configured with a lever 29 connected to a bearing cap 30, which is attached to the lever 29 by replacing a pair of bolts 31 and 32 so that the center of the rotary shaft 28 is installed between the two parts described. The rotary shaft 28 at the location of the transfer pipe 23 is made with a multifaceted segment 33, which ends with an oversize 34 of increased diameter. In this way, axial fastening of the nozzle 23 to the shaft 28 is carried out. A lindric portion 35 of smaller diameter adjoins the shoulder 34, which rests on a combined angular contact ball bearing 36. At its opposite end, the multi-faceted portion 33 adjoins the cylindrical portion 37 of a smaller diameter, which continues with shaft 38 even more diameter. A nut 39 and a lock nut 40 are screwed onto this shaft. With the help of nuts, the rotary shaft 28 is fastened to the composite washer 41, which in turn is pressed against the sleeve of the thrust bearing 42, which is loaded through the nozzle 23 in the opposite direction to transportation. The rotary shaft is driven by the movement of the piston 43 through the crank 44, which (figure 5) acts on the end 45 of the shaft 28, made with keyways 46. While the cylindrical end of the shaft 28 passes only in the bearing 36 (figure 5) it The end of the shaft 28, according to the example shown in FIG. It has a support structure that corresponds to the support bearing cover 13. With the help of nuts 47 and 48, the second end of the rotary shaft 28 can also be fixed, thereby preventing the deformation of parts that perceive axial loads. The keyways 46 are therefore located behind the nuts 47 and 48, which make it possible axially to fix the shaft on the bearing 49. The turn shaft 28 with the branch pipe 23 suspended thereto rests with its axis at least on one of the bearings 42 and 49, which are located on the walls of the casing 2. At the same time, the inlets 5 and 6, which are in contact with the pipe 23 or its sealing rings 26 and are made in the disk 4, are placed in such a way that the distance from their axes or centers of gravity to the axis of the rotary shaft is greater than the corresponding Russ of from about the outlet axis. The pipe 23 is positioned in such a way that it with its ends1 and covers one of the two outlets 5 or 6 and the outlet. A port 23 or its lever 50 (Fig. 5) or 29 (Fig. 3) connected to the rotary shaft 28 are in the desired position depending on the rotary shaft. The ends of the pipe 23 are located in front of the plate I6 and the wall 12 and the required clearance is adjusted by means of rings 25 and 26 with grooves. In addition, in the pipe 23, there are two axes which, if necessary, connect one of the two outlets with the inlet. These axes are inclined more than is required if the holes are at the same distance from the axis of the rotary shaft. The inclination angle should be kept relatively small, therefore the outlet opening (Fig. 4) is renal shaped. A form in which, in the case of a larger inclination angle, both outlet openings are reduced to one. The use of the invention will significantly reduce the mechanical load on the chamber wall without increasing the bending load acting on the rotary shaft, which will increase the reliability of the device in operation and service life.
