Description

The invention relates to military tracked vehicles, in particular to systems for preheating power plants of military tracked vehicles (VGM).

Known systems for heating tanks and infantry fighting vehicles containing heaters of various designs. The launch of well-known analogues of heating systems for power plants is possible only with the participation of the driver, since the means and controls of the heating system (heater) of the VGM power plant are installed at the driver’s workplace or separately from the driver’s place (separated by the VGM object).

As a prototype, the heating system of the power plant of the T-72 tank was taken (see Technical description of the T-72 tank. - M .: Military Publishing House 2002, p.99). The heating system includes a heater, which consists of a boiler, exhaust manifold, supercharger, electric motor, water pump, fuel pump, nozzle, fuel valve, glow plug and glow plug.

One of the main measures to ensure high combat readiness is the preparation of the power plant for the movement of the high-speed military. The practice of operating the VGM in the troops has shown that preparation for movement, especially at negative ambient temperatures (winter), is to a decisive extent determined by the time required to prepare for the launch (warm-up) of the VGM power plant.

Preparation for the movement of the VGM is carried out by the driver after arrival in the park of a military unit from the location of the unit.

Parks of military units, as a rule, are located at a considerable distance from the locations of the personnel of units. Therefore, the arrival time of the crews (driver mechanics) to the VGM samples in the park is significant. Consequently, the arrival time of the crews (driver-mechanics) to the VGM samples remains unused for the preparation of the VGM power plants for launch, while the overall execution time of the assigned combat mission increases, which is a significant drawback in the system of basic measures for ensuring the combat readiness of units.

On the existing heating systems of the VGM power plants, including the selected prototype, the remote start of the heating system of the power plant at any time of the day and a certain period (winter, summer) of the operation of the VGM is not provided. Thus, in this case, the preparation of the power plant for launch is possible only with the direct presence of the crew (driver) in the VGM facility, which is a significant drawback of existing similar systems for heating the power plant.

The purpose of the proposed technical solution is to provide automatic preparation of the VGM power plant for launch, regardless of the time of day, a certain period of operation of the VGM, as well as the location of the crew (driver-mechanic).

To achieve this goal, a device is proposed for automatically preparing the power plant of a military tracked vehicle for launch, containing a heater including a boiler, exhaust manifold, supercharger, electric motor, water pump, fuel pump, nozzle, fuel valve, glow plug and glow plug, characterized the fact that in the heating system of the power plant an additional control unit is installed with a remote control panel, while the control unit is connected to a spark plug and a candle under overheating, fuel valve, a motor, a temperature sensor and a heater installed boiler flame temperature sensor and the actuator of the exhaust manifold cover, and a heat exchanger mounted temperature limiter.

The invention is illustrated in figure 1. A general view of the structural diagram is shown in figure 1, where it is indicated: fuel valve 1, fuel pump 2, electric motor 3, air blower 4, coolant pump 5, exhaust manifold cover 6, exhaust manifold cover cover 7, exhaust manifold cover 8, heat exchanger 9, temperature sensor 10, heating limiter 11, control unit 12, flame sensor 13, glow plug 14, glow plug 15, nozzle 16, boiler 17, remote control 18.

The proposed device operates as follows. The signal from the control panel 18 for starting the heater is received by the antenna of the control unit 12 included in the VGM electric network. The control unit 12 issues a command to the actuator of the exhaust manifold cover 7, which opens the exhaust manifold cover 6. Also, the control unit 12 opens the fuel cock 1, supplies voltage to the glow plug 15 and the glow plug 14 to glow for a certain time (at least three minutes) . Fuel begins to flow to the nozzle 16, where it is heated by the glow plug 15 to ensure normal ignition. After a certain time (at least three minutes), the electric motor 3 is turned on, the air blower 4 rotates, the coolant pump 5 and the fuel pump 2. Fuel under pressure is supplied to the nozzle 16, is sprayed in the boiler 17 and ignites, falling on a hot glow plug 14. With steady combustion, a signal is received from the flame sensor 13 to the control unit 12, while the control unit turns off the glow plug 14, the glow plug 15. The heat generated during combustion is transferred to the coolant of the cooling system the power plant through the heat exchanger 9. Coolant is circulated in the cooling system by the coolant pump 5. When the coolant reaches 90 ° C, the temperature sensor 10 sends a signal to the control unit 12, which shuts off the fuel valve 1, and the fuel does not flow to the nozzle 17 As a result, the flame in the boiler 17 goes out. In this case, the electric motor 3 continues to operate for a certain time (at least forty seconds) to purge the boiler 17 of the heater. After that, the control unit 12 stops the operation of the electric motor 3 and issues a command to the exhaust manifold cover 7, which closes the exhaust manifold cover 6. The exhaust manifold cover 6 prevents water, dust, dirt, and other foreign elements from entering the exhaust manifold 8.

To protect against unacceptably high operating temperatures, a heating limiter 11 is provided. At a heat exchanger temperature above 120 ° C, the signal from it enters the control unit 12, which closes the fuel valve 1, and the fuel does not enter the nozzle 17, as a result of which the flame in the boiler 17 goes out . After that, the heater can start after cooling and troubleshooting.

Thus, the proposed technical solution allows you to automatically prepare the VGM power plant for launch, regardless of the time of day, a certain period of operation of the VGM, as well as the location of the crew (driver-mechanic).
