Abstract
The utility model relates to a diesel engine fire-fighting pump unit with a self-cooling function. The diesel engine fire-fighting pump unit comprises a diesel engine, a fire-fighting pump, a gate valve, a pressure reducing valve, a pressure gauge and a heat exchanger, and is characterized in that an outlet of the fire-fighting pump is connected with a side pipe; the side pipe is connected with the pressure reducing valve by the gate valve and is communicated with the heat exchanger; an inlet of the fire-fighting pump is connected to the outlet end of the heat exchanger; and a circulation pipeline in the diesel engine is connected with the heat exchanger. The diesel engine fire-fighting pump unit has the advantages that circulating water in the diesel engine is cooled by utilizing an external water source, so that diesel engine fire-fighting pumps can still run normally under the condition of poor ventilation.
Description
Technical field
The utility model relates to a kind of novel having from the diesel powered fire pump group structure of cooling off function.
Background technique
Diesel engine cycle water generally is made up of fan and water tank, and the motivational drive fan by diesel engine self when unit operation reaches the cooling purpose.This type of cooling is higher to the space and the air-conditioning requirement of pump house, and also the power of loss diesel engine own particularly when pump house can not meet the demands, can make diesel engine cycle water not reach cooling effect, causes unit normally to move.Therefore must the structure of diesel powered fire pump group be improved, just can make circulating water obtain cooling, guarantee the normal operation of Diesel engine pump group.
Summary of the invention
The purpose of the utility model is to solve diesel powered fire pump of the prior art not reach the problem that requires existing circulating water can't cool off diesel engine because of the space of pump house with ventilating; A kind of novel having from the diesel powered fire pump group of cooling off function is provided; The utility model design has from the diesel powered fire pump group of cooling off function, comprising: diesel engine, fire water pump, gate valve, reduction valve, pressure gauge and heat exchanger; It is characterized in that: be connected to other pipe in the fire water pump outlet; Other pipe connects reduction valve by gate valve and is communicated to heat exchanger again, and the outlet end of heat exchanger has connecting tube to connect the import of fire water pump, and the diesel engine inner loop pipeline connects heat exchanger.The utility model has the advantages that and utilize outer water source, guarantee under the situation of improper ventilation, still can make the diesel powered fire pump proper functioning the lowering the temperature of circulating water in the diesel engine.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Comprise among the figure: diesel engine 1; Fire water pump 2, gate valve 3, reduction valve 4, pressure gauge 5 and heat exchanger 6; It is characterized in that: be connected to other pipe 7 in the fire water pump outlet; Other pipe connects reduction valve by gate valve and is communicated to heat exchanger again, and the outlet end of heat exchanger has connecting tube 8 to connect the import of fire water pump, and diesel engine inner loop pipeline 9 connects heat exchanger.
Its working principle is exactly after fire water pump operation, to utilize the outer circulation water of the high pressure fire fighting water of pump discharge as heat exchanger, when high pressure fire fighting water through the reduction valve rated pressure input heat exchanger of heat exchanger that reduces pressure, and then be back to the import of fire water pump.The heat of circulating water will be taken away by outer circulation water in the diesel engine like this, reaches cooling purpose.
