Main features of diesel pump set:
1. Automatic operation: when the diesel engine fire pump unit receives the effective fire signal and remote control start signal, the unit will start automatically. When the power supply system of the motor fire pump unit is cut off to form the signal of phase loss, the unit will be in special state automatically. If the diesel engine fire pump set starts for 10s and fails to start, it will stop for 10s and then restart. The unit will automatically repeat three times;
2. Automatic charging: the unit will be charged automatically when the battery voltage is low when the battery is in standby mode at the automatic position. When the battery voltage is sufficient, the charging can be stopped automatically to avoid damage to the battery;
3. Automatic alarm: multiple start failure alarms, diesel engine low oil pressure alarm, diesel engine water temperature alarm, diesel engine ultra-high speed alarm and shutdown, battery low voltage alarm, charging failure alarm, fuel lack indication alarm, etc.
4. Automatic preheating: keep the diesel engine in hot standby state to ensure emergency work;
5. Direct connection: the diesel water pump unit below 360kw adopts the technology of direct connection of diesel engine and water pump through elastic coupling, which is the first in China. It reduces the failure point, greatly shortens the starting time of the unit, and increases the reliability and emergency performance of the unit;
6. Users can also request to set other alarm output (non-standard supply);
7. It has telemetry, remote signaling and remote control functions (non-standard supply);
8. Wide range of type spectrum: single stage single suction pump, multi-stage single suction pump, single stage double suction pump, etc. can be selected for the fire pump set. Or a variety of pump combinations in parallel, wide range of flow, pressure.

Diesel engine selection
Diesel engine
1. Single cylinder or double cylinder diesel engine shall be used for power less than 20kW;
2. Q385 is used for power 20kw-30kw.
3. Power: 30kw-56kw four cylinder diesel engine 4100, 4102, 4108, etc.
4. Power: 70kw-300kw six cylinder diesel engine 6105, 6113, 6135.
5. Power 300kw-2000kw8, 12, 16 cylinder diesel 12v135azd, kt38, etc.
How to select type
1. The rated power of the selected diesel engine shall be greater than 10% of the maximum shaft power of the water pump. Under abnormal conditions, the power of the diesel engine will not reach the rated power. In order to ensure normal operation, it is necessary to select a high-power diesel engine and water pump. Note the rated power of diesel engine is measured under the following standard conditions;
2. The ambient atmospheric pressure is 100KPA.
3. Ambient temperature 25 ℃.
4. Air relative humidity 30%.
5. When the altitude of the working place is increased by 100m, the power will be reduced by 3%.
Fuel tank selection
Tank capacity
The fuel tank capacity is generally 190-250g / kW. H per hour under rated power load. Calculate the 6-hour fuel consumption, leaving 10-15% margin.
Capacity of oil storage tank
The capacity of the main fuel oil storage tank (tank) is calculated based on the expected rated fuel consumption and operating time. In the design of fuel tank capacity, the minimum fuel supply for continuous operation shall be taken as the standard;
Tank installation
1. It is recommended that the user install an oil-water separator on the oil supply pipeline;
2. When connecting the pipeline of the oil tank, it is strictly prohibited to use ordinary raw material to bring sealing, so as to prevent the pipeline from entering the diesel engine due to dissolution, resulting in pipeline blocking;
3. The installation position of oil tank shall avoid heat source and vibration, because vibration will cause sediment to rise, while heating will cause power drop;
4. Considering the fire protection requirements, it is recommended to place the oil tank above 1000L separately and isolate it from the diesel engine fire pump set;
5. Fuel temperature is an important factor that affects the good operation of diesel engine. The oil temperature higher than 60 ℃ will lead to volume expansion, obviously reduce the heat capacity per unit volume of fuel oil, reduce the output power of diesel engine, and avoid the influence of external heat source on the oil temperature;
6. It is suggested that the installation position of the oil tank should be such that the maximum suction head is not more than 2m, and the suction head of the output pump should be calculated from the bottom of the oil tank;
7. The oil tank shall be kept away from the sun. The oil tank shall be placed away from the fire source. Smoking is not allowed near the oil tank. Sparks or flames are not allowed. Volatile fuel will cause explosion. And there should be corresponding fire fighting facilities (such as foam extinguisher, sand, etc.) near the fuel tank. Strictly prohibit the use of water as a fire fighting material. It is recommended that the fire tank department should get the approval of the fire department when placing the fuel tank larger than 2000L.
The following is the selection function, which is proposed when ordering:
1. The speed can be adjusted. When the flow and head of the water pump are inconsistent with the actual requirements, the speed of the diesel engine can be adjusted to meet the actual situation.
2. battery circuits, one for use and one for standby.
3 maintenance free battery, no need to add replenishing fluid for maintenance.
4 preheat to ensure normal startup at low temperature.
5 regular patrol inspection can be set to ensure the normal operation of the unit.
6. Data remote transmission, which can realize the function of data remote transmission. The operation of the device can be seen in real time by using app on the mobile phone.
7.The protection level of 7 houses is increased to IP44.
8 different brands of diesel engines.
