Изобретение относитс  к транспортному машиноетроенню, в частности к устройствам дл  регулировани  температуры охладител  дизел  тепловоза.This invention relates to a vehicle chiller, in particular to devices for controlling the temperature of a diesel locomotive cooler.

Известпы устройства дл  автоматического регулировани  температуры в системе охлаждени  дизел  тепловоза, содержаи-Uie вентил тор с исполиительным механизмом, датчик температуры и реле, включеииое в цепь управлени  жалюзп холодильника.The devices for automatic control of the temperature in the diesel engine cooling system of a diesel locomotive are known, containing a fan with an actuating mechanism, a temperature sensor and a relay included in the louver control circuit of the refrigerator.

Цель изобретени  - уменьшение етатичегской перавпомериости регулировани  температуры ири установившемс  ироцессе регулировани  дизел . Это достигаетс  тем, что устройство сиабжено датчиком мощности дизел , св занным пневматически с его органом топ .ливонодачи и сумматором, выход которого пневматически подключен к исиолпительному механизму и реле, а входы - к датчикам мощности и температуры.The purpose of the invention is to reduce the efficiency of adjusting the temperature control and the steady-state process of controlling the diesel. This is achieved by the fact that the device has a diesel power sensor that is pneumatically connected to its top oil supply body and an adder, the output of which is pneumatically connected to the actuator and the relay, and the inputs to the power and temperature sensors.

На чертеже схематически показано описываемое устройство.The drawing schematically shows the described device.

Оно содержит веитил тор 1, приводпмый во враи1,еиие от двигател  виутреннего сгорани  (на чертеже не показан) носредством привода с исполиительиым механизмом 2, управл емым давлением Р воздуха, выход щим из сумматора 3 и подводимым также к пиевмоэлектричеокому реле 4 давлени , упра вл ю .щему жалюзп холодильника (на чертеже не It contains a fan 1, driven from the engine of the morning combustion (not shown) by means of a drive with a control mechanism 2, controlled by air pressure P, coming out of the adder 3 and supplied also to the pyrethromotive pressure relay 4, the controller to the cooler’s louver

показапы). Сумматор 3 воздухопроводами св зан с выходами пневматпческого датчика 5 температуры в спстеме охлаждени  и датчика 6 моииюсти двигател  внутреннего сгорани , преобразующего перемещение органа тоиливоподачи (штока) 7 регул тора скорости 8 двигател  в давление Ро воздуха.shows) The adder 3 is connected to the outlets of the pneumatic sensor 5 of temperature in the cooling system and sensor 6 of the engine of the internal combustion engine, which converts the movement of the body of the feed unit (rod) 7 of the engine speed controller 8 to the air pressure Po.

При низкой температуре /i (ннже нижнего предела диапазона регулнровани ) охлаждающей среды двигател  давление РЗ воздуха на выходе датчнка 5 н давленне Р на выходе сумматора 3 - папбольщее. При этом контакты реле 4 разомкнуты, жалюзи холодильника закрыты п исиолнительпый механизм 2 находитс  в положении, когда производительность вентил тора 1 равна нулю. При повышении темиературы охлаждающей среды двигател  давлеиие РЗ воздуха на выходе датчика 5 снижаетс ; при некоторой его величине контакты реле 4 замыкаютс  п жалюзи холодильника открываютс . При дальнейщем повыщеиии темиературы fi охлаждаюп1ей среды двигател  и поиижепии давлени  РЗ на выходе датчика 5, а значит, в исполнительном механнзме 2 (вначале сумматор 3 работает как повторитель, и давление Р1«Рз) производительность вентил тора 1 начинает увеличиватьс , и повышение температуры t прекращаетс .At a low temperature / i (below the lower limit of the adjustment range) of the engine cooling medium, the pressure of the air of the air at the output of the sensor 5 n pressure P at the output of the adder 3 is popular. At the same time, the contacts of the relay 4 are open, the louver shutters of the refrigerator are closed. The two-way mechanism 2 is in the position when the capacity of the fan 1 is zero. With an increase in the temperature of the cooling medium of the engine, the pressure of the RZ air at the output of the sensor 5 decreases; at a certain value, the contacts of the relay 4 are closed and the fridge blinds open. As the temperature fi increases further, the engine environment cools down and the RP pressure increases at the output of sensor 5, which means that in actuator 2 (first, adder 3 works as a repeater and pressure P1 "Pz), performance of fan 1 begins to increase, and temperature rise t stops .
