Listed below are the parts that make up the proposed pump, and their purpose.

Mechanism 1 (Figs. 1 and 2) for transmitting the movement of the piston from the power source, consisting of a bed with main bearings, a crankshaft, a crank, a crosshead and a wedge-shaped connection of the latter with the piston; hollow seed pryshchen 2 pump (Fig. 1 and 2); cylinder 3 of the pump with the gland (Fig. 1 and 2); concentric grooves 4 (Fig. 1) on the spherical surface of the rear part of the cylinder, which are connected by radial grooves to the central part of the cylinder and which are used for suction of the diaphragm over its entire surface; Crane 5 (Fig. 1 and 2) for lowering the air and blowing the cylinder; tides 6 (Figs. 1 and 2) in the cylinder for locating taps 5 therein; a valve or a faucet 7 (Fig. 1) of a large section, when opened, the pump stops pumping, does not stop the operation of other pumps, since the movements of the piston create only the movement of air through the valve, without causing the diaphragm to oscillate; pipe 8 (fig. 1 and 2) with a flange, is cast from one whole with the cylinder and is located equally in all pumps; reservoir 9 (fig. 1, 3, 4, 5 and 6) of the regulator, the volume of which is not less than four volumes, described by the piston per Va pump turn; when the cylinder is filled with water, about half of its capacity is poured into the tank, therefore all excess water that returns to the tank through the discharge valve 20 (maximum of excess water is equal to the volume described by the piston per 2 turn of the pump) is freely placed in the tank without splashing out Camping out, and in subsequent moments, again take part in the pump operation processes, so that the addition of new portions of water during the pump operation is not required; gauge glass 10 (Fig. 1), showing the water level in the tank 9; a valve or faucet 11 supplying water from the water supply to the reservoir 9; cover 12 (fig. 1 and 3) of the regulator, which is mounted on the gasket and hermetically closes the reservoir 9; pipe 13 (Fig. 3) for the passage of air from the tank 9 during operation of the pump; a disk 14 (FIGS. 1 and 3), attached to the lid 12 and serving as a shield reflecting the water splashes, which, together with the air, get to the outside through the pipe 13; nest 15 (figs. 3 and 4) of the regulator injection valve; socket 16 (FIGS. 3, 4 and 5) of the regulator suction valve; gaskets 17 (Figures 3, 4 and 5) for sealing the nests; plates 18 (Figs. 1, 3, 4, 5 and 6), pressing the valve sockets and preventing them from jumping out of their seats under the influence of valve shocks; stud bolts 19 (fig. 1,

5 and 6), pressing plates 18; pressure valve 20 (Fig. 1 and 3) of the regulator; rod 21 (Fig. 1 and 3) of the discharge valve 20; plate 22 (Figs. 1 and 3), serving as a guide for rod 21; stuffing box 23 in plate 22 for sealing rod 21; spring 24 (FIGS. 1 and 3), pushing the valve 20, wherein the degree of its pressure creates the desired limiting pressure in the pump; a screw 25 (FIG. D) with handles for adjusting by hand the degree of pressure of the spring 24; a nut 26 (FIG. 1) of the screw 25, which is mounted on two plates with the aid of two columns; a lock nut 27 (fig. 1) with two tabs, by means of which the correct position of the screw 25 is fixed by hand, at which it does not allow the screw 25, under the influence of valve 20 blows, to move away arbitrarily from its position, so that an arbitrary change in the degree of pressure is impossible springs 24 to valve 20; suction valve 28 (FIG. 3) of the regulator; rod 29 (FIG. 3) of the suction valve 28 with a thread at the upper end; plate 30 (Fig. 3), serving as a guide for rod 29; sleeve 31 (Fig. 3) in which the eraser; Ken 29 passes freely and which serves as a guide spring 32 and as an emphasis for sleeve 33 when the rod 29 oscillates; spring 32 (FIG. 3), tending to pull the valve 28 upwards; sleeve 33 (FIG. 3) is loosely fitted onto the rod 29 and serves as a guide for the spring 32 and as an emphasis for the sleeve 31 and for the nut 35; the gap 34 (Fig. 3) between the sleeves 31 and 33; nut 35 (Fig. 3) with a roll (it is shown in the drawing by zigzag lines) for adjusting the gap 34 by hand, i.e. the magnitude of the span of the rod 29 on which the degree of pump suction depends (i.e., the pump recoil is useful); rod 29 is oscillating up to / 2 mm, i.e. the gap 34 has a size up to mm, so the regularity of the action of the valve 28 is to give pressure uniformity and high

the efficiency of the proposed pump; the spring spruce lock nut 36 (Fig. 3 and 9) fixes the position of the nut 35; a lamb 37 (FIGS. 3 and 9) with a screw secures the lock nut 36 on the rod 29; the nut 35 (Fig. 3) is fixed with the rod 29, which does not change its position under the action of the nuts 35 and 36; The rubber diaphragm 39 (FIG. 1), which oscillates, is guided by the movement of the piston 2, and performs on its other side, in the pipe 41, the same effect as the piston (i.e., it dilutes when the piston is thinning, and produces compression when the piston does it); the cover (Fig. 1) of the cylinder 3 is bolted on to it; pipe 41 (FIG. 1), molded with the lid 40 in one piece, connects the suction and discharge valves on the pumped liquid communication line; a valve or valve 42 connected to the pipe 41 serves to discharge the air accumulated in the pipe and restore normal operation of the pump; box 43 (FIG. 1) of the suction valve; box 44 (Fig. 1) of the discharge valve; the main socket 45 (Fig. 1) on the thread in the suction valve; the main socket 46 (Fig. 1 and 7) on the thread in the discharge valve; an additional socket 47 (FIG. 1) in the suction valve; cap 48 (Fig. 1) with legs controls the lifting of the ball 51 in the suction valve; cap 49 (Fig. 1 and 7) with tabs in the discharge valve; sleeve 50 (Figs. 1 and 7) on the thread serves as the upper guide rod 57 of the discharge valve; The ball 51 (FIG. 1) serves as a suction valve; a gasket 52 (FIG. 1) for clamping the cap 48 tightly with an upper cap 53 in the suction valve; a cap 53 (FIG. 1) of a suction valve; cover 54 (FIG. 1) of the discharge valve; bracket 55 (fig. 1) with screw, pressing cover 53; bracket 56 (fig. 1) with screw, pressing cover 54; rod 57 (FIGS. 1 and 7) of the discharge valve; lower guide (lock-nut) 58 (figs. 1, 7 and 8) will force the valve; a metal disk 59 (Figs. 1 and 7), which is screwed with its thread onto a rod 57; disk 60 (Fig. 1 and 7) (soft gasket); metal disk 61 (Fig. 1 and 7); the nut 62 (FIGS. 1 and 7) presses the discs 61 and 60 against the disc 59 and fastens itself with a lock nut 58; pin

63 (FIG. 7) holds the lock nut 58 in a dead position; spring

64 (Fig. 1 and 7) produces instantaneous closing of the discharge valve, which is important for the pump to work properly (the spring action is so strong that grains of sand and other small objects in the liquid cannot brake it); valve or valve 65 (Fig. 1) for removing, if necessary, fluid from the discharge valve box 44; valves 66 and 67 or taps (FIG. 1) serving to shut off a diaphragm pump; pulley coupling 68 and coupling 69, which serve to connect the pumps and give the crankshafts proper positioning of the water plunger pumps.
