Description

POMPA MANOMEA-RICHESKAYA SALT.

The utility model relates to measuring equipment and can be used for checking and calibrating deformation gauges in the laboratories of the NIP of industrial enterprises and in repair shops.

A known portable piston manometer containing a measuring device, including a calibrated pressure gauge and a measuring column, a device for creating pressure, including a press, a reservoir with a working fluid, channels for supplying and discharging a working fluid and shut-off valves 1.

The disadvantage of this device is that the housing is made welded and after welding it is necessary to finish the surfaces under the calibrated pressure gauge and measuring column.

The closest in technical essence and the achieved result is a portable piston manometer, consisting of a measuring device and a device for creating pressure, which includes a press, a reservoir with a working fluid and channels for supplying and discharging a working fluid and shut-off valves 2.

The disadvantage of this device is that this pressure gauge is inconvenient during assembly.

The device for creating pressure consists of a plate T (base), on which a press 2 is placed, consisting of an outer 3 and an inner 4 cylinder and a cylinder 5, with a flywheel b, with a tank 7 for filling the working fluid and with a valve 8, the right body 9 for installation of the piston column, consisting of a cylinder 10, a piston II with a position indicator 12 and a load-bearing disc 13. The left housing 14 for installing the calibrated pressure gauge 15. Shut-off valves 16 and 17 are located on the housings 9 and 14. Plate I is mounted on the support leg 18, intended for installation level deadweight column. Threaded bushings 19 are screwed to both ends of the press 2. Using the nuts 20, the press 2 is pressed against the housings 9 and 14.

The pump is a device operating on the principle of the action of an uncompressed piston, the rotation of which (by hand) during operation is a prerequisite for eliminating friction in the piston pair, which affects the measurement accuracy. For operation, the pump using the support legs 18 is set at the level. A verifiable pressure gauge 15 is installed in the housing 14, the valves 16 and 17 are closed and the valve 8 is opened, then, by rotating the handwheel b of the press 2, they are pumped in a clock system clockwise. 3-4 working fluid. Then close the valves 16 and 17 and create pressure in the system by rotating the flywheel 6 counterclockwise. Weights are imposed on the load-receiving disk 13, the mass of which must correspond to the pressure on the device being verified.
