Description

BASIC Auth. St. No. 133096 describes a device for measuring the average efficiency value. Enegistic installations, in which two measuring devices with counting mechanisms are used, taking into account: the first — the total consumption of the driving factor of the installation (liquid fuel), and the second — respectively, the amount of electric energy produced during this time, as well as the contact device, which records the electricity meter readings at consumption of a given amount of fuel.

The proposed device is a further development of the device according to the author. St. No. 133096 and differs from it in that the electricity meter is equipped with an electromagnetic printing mechanism, driven by pulses of the counting mechanism of the second device.

Such an embodiment of the device makes it possible to automate the process of fixing measured quantities of electrical energy.

FIG. 1 given electrical circuit device; in fig. 2 - device, general view; in fig. 3 - the same, side view.

The described device measuring the efficiency power plants, includes a driving factor sensor (steam, fuel, water) and a useful effect sensor (heat, steam). A series of radial stripes is applied on the disks of the counters of sensors with a matte black paint. In the case of the photoresistance counters 1FS and 2FS and the 1L and 2L bulbs are mounted so that only the light reflected from the disk is incident on the photoresistance. When the disk is rotated, the ohmic resistance of the photoresistance will change as many times as the bright bands that are above it. Consistently with each photoresistance, one of the windings / polarized relays 1РП and 2РП, the second windings // of which are included opposite with the windings /

No. 143097 .. 2 on the housing position removed from the dividers R: and. Polished relay / P / I retracts. Electromechanical counter 1CI pulses, counting out iiiiifti nocTofiliHbie amount of a driving factor. The counter emits. ONE pulse when a certain number of pulses are read from the sensor, the ICHi contact of the counter is connected to the core and is closed when each trigger is triggered, and the other 1CI when the counter is set to the specified number. At this moment both ICMi and 1SI2 contacts are closed and the output pulse begins. The number of lanes on the disks of the primary sensors and the number of pulses, after which the output pulse of the 1SI counter is given, is chosen so that the numbers corresponding to the efficiency value are printed on the paper tape. power plants without conversion factor.

Relay 2 FIR includes an electromechanical counter 2SI. Each time it is triggered, the bark of an electromagnet rotates through gears the first decimal drum, on which rubber convex figures are mounted. A movable frame / on which two coils of 2 and 3 s are mounted is mounted above the counter. paper tape. The tape of the reel 2 passes around the rotating roller 4 onto the roller 3. With the pressure bar 5, the paper is pressed against the drums and numbers against the bar are printed on it. The drums are continuously lubricated with a strip 6 of soft porous mass 6 soaked in ink.

The device works as follows. Both electromechanical meters count incoming pulses from sensors. When the number of pulses on the 1SI meter reaches a certain value, it turns on the PS printing solenoid with its ICHi and ICMz contacts. To the core of the solenoid PS attached gear rack 7, made in the form of a cylinder with annular grooves. When the core is pulled in, the rail rotates gear 8, mounted on axis 9, counterclockwise. At the beginning of the rotation, the cam mounted on the axle pulls down the lever W together with the frame, on. which it is fixed. In this case, the reading of the 2SI meter is printed on paper. After the end of the pulse from the 1SI counter, the spring returns the core of the PS solenoid and the rest of the mechanisms to their original position.

On the same axis with the drums, counting the value of efficiency gear 11 and a number of digital drums counting down time are installed. Their drive is carried out from the synchronous motor DM through a carrier / 2, a four-beam sprocket 13, gears 14 to 11 with a ratio of 1: 2.5 and one of the gears-paratroopers 14. With this transfer, the first drum moves every second discretely figure. If necessary, the gear ratio can be changed.
