Detailed explanation of main features of diesel water pump unit
The biggest difference between a diesel water pump unit and an electric water pump is that it has its own independent power supply system—battery. Therefore, the startup and operation of the diesel pump can be completely separated from the city power.
The diesel water pump unit is usually used as a backup facility. Therefore, it will start automatically only when the signal comes, and the electric water pump fails or the power supply is cut off. When it has an ultra-low pressure pump starting device, the electric water pump control cabinet supporting it should also have an ultra-low pressure pump starting device, and the lower limit of the two pump starting points should have a certain pressure difference. Of course, I can also design a control system that better suits the needs of the customer according to the customer's requirements.
The main features of diesel pump set are detailed as follows:
1. Strong power: The overall crankshaft of the diesel unit has high rigidity, high strength, and high torque transmission efficiency.
2. Advanced technology: It adopts international advanced technology and gantry type body, sliding bearing, plate-fin type cooler, top-mounted heat exchanger, spin-on oil filter and double cooling system.
3. Superior performance: The smoke level and noise index reach the national premium products, and the fuel consumption is lower than the national standard premium products by 2.1g / kW.h or more.
4. High degree of automation: It has automatic, manual and automatic fault detection functions, monitors the working status during the whole process, can recover from faults and restarts automatically, and automatically pre-lubricates and pre-heats to make the equipment start more safe and reliable; with a central control room Remote control and remote control functions, and can also have field bus connection (optional function). The battery adopts full-automatic floating charge (constant current, constant voltage, trickle charge) electric mode to ensure that the battery is in a standby state at any time.
5. Convenient to use: Equipped with remote transmission instruments and meters, which can be connected to the control center as required, easy to install and use, and easy to maintain.
Deconstruction function characteristics of diesel engine water pump unit:
1. Automatic start: after receiving the fire alarm / pipe network pressure / power failure / or other start signal, the diesel water pump unit can start automatically and put into full load operation within 15 seconds;
2. Automatic charging: The battery can be automatically charged by the mains or diesel charging motor to ensure the smooth start of the unit;
3. Automatic alarm: automatic alarm protection for diesel engine low oil pressure, high water temperature and other faults, alarm and stop when overspeed;
4. Automatic preheating: keep the diesel engine in the state of hot engine standby to ensure emergency work;
5. Direct connection type: The diesel water pump unit below 360kw adopts the first domestic direct connection technology of diesel oil return machine and water pump through elastic coupling, which reduces the fault point and greatly shortens the start time of the unit, which increases the reliability of the unit And emergency performance;
6. The user can also request to set other alarm outputs: the diesel-powered drive pump (or fire pump set) is installed safely and tightly on a common chassis by horizontal centrifugal pumps and diesel electrical instruments and other equipment. Through the control line and electric control Box connected.
