Description

Lubricating devices of locomotives, which enclose a press-lubricant with plunger pumps for lubrication and with levers limiting the stroke of the plungers, are known.

In order to provide in such a device, when the locomotive moves with a closed regulator, to turn off pumps, to lubricate them in sliding spools, an air servomotor is used that acts on the arms limiting the plunger stroke, the air duct connecting the servo motor to the main tank, and placed on the air duct a valve articulated with a diaphragm located on one side under the action of air pressure in the main tank, and on the other under the action of vapor pressure in the spool box of the locomotive and the pressure of dinners.

The drawing shows a diagram of the proposed lubricating device of a locomotive.

The device includes a press machine 1, a servomotor 2 and a shut-off valve 3.

In the cylinder 4 of the servomotor 2, the shaft 5 is located. The rod 6 of the shaft 5 is connected with the rod 7 with the rod 8, which is articulated with the levers limiting the stroke of the piston knives 1, but not lubricating the sliding spools. Return przzhina 9 squeezes Porschen in the left side of the drawing.

The air pipe 10 communicates the servomotor cylinder through a shut-off valve 3 with the main reservoir 11.

The diaphragm 12 of the shut-off valve 3 is under the action of the pressure of the air coming from the main tank through the pipeline W from the upper side, and under the action of the pressure of the steam supplied from the spool box and the pressure of the spring 75 from the underside.

When a locomotive with an open regulator moves, the total pressure of the steam and the spring and diaphragm grows higher than the air pressure. Therefore, the diaphragm bends upward and the valve 3 articulated with the diaphragm blocks air access from the main reservoir to the servomotor piston. Therefore, the piston occupies the left position shown in the drawing, corresponding to the position of the normal operation of all plungers and press maslenka /.

When the regulator is closed, steam does not flow under the diaphragm 12, and the pressure from the upper side of the diaphragm does not come. sags

way down. The valve 3 at the same time opens the passage of air into the servomotor through the air pipe 10.

The piston of the servo moves to the right, and the rod 8 moves the plunger limiting arms of the pumps supplying lubricant to the spools to the off position of these pumps from operation.

A lubricant device of a steam locomotive that incorporates a lag-and-blind with plunger pumps for supplying lubricant and with levers limiting the stroke of the plungers, or about

The purpose of shutting down the operation of a locomotive with a closed pump regulator, supplying them with lubricants in sliding spools, was not equipped with an air servomotor, acting on the levers limiting the stroke of the plungers, the air line connecting the servo motor to the main tank, and a valve connected to the air line a diaphragm located on one side under the action of the pressure of the air in the main tank, and on the other side under the action of the pressure of steam in the spool box of the locomotive and the pressure of the spring.
