Start-up Function of Small Diesel Engine Fire Pump Set

Three start-up functions for diesel engines:
1. Manual start function: manual and automatic interlocking can be completed through the transfer switch, and the manual start function can be realized:

2. Automatic manual function: allow to start three times. If the startup fails for three times, it will issue a “startup failure alarm” and automatically exit the startup state. After a successful startup, the time from startup to rated load is 5-10-15S (depending on the unit capacity);

3. Emergency manual direct start function: When the automatic control device fails, the emergency manual direct start function can be realized.

Main features of diesel engine fire pump:
1. Fully automatic start: After the diesel water pump diesel generator set receives a safety accident/pipeline network working pressure/power failure/or other starting data signals, it can start automatically within 15 seconds and operate the fund management load;
2. Automatic charging: the battery can be automatically charged by the working standard voltage or the diesel engine battery charging motor to ensure the successful start of the diesel generator set;
3. Fully automatic alarm: automatic alarm maintenance for difficult problems such as low air pressure and high temperature of diesel engine, alarm and shutdown at speed limit;
4. Fully automatic heating: make the diesel engine in the condition of embedded parts of the heat engine to ensure emergency work.

    More Fire Pump Set

    There are many types of fire-fighting equipment, fire hydrants and fire extinguishers are a common category, and there is also a category of fire pumps, which can be described as the heart of the fire-fighting system and play an important role in pressurising the water supply for the fire-fighting system. Among the many fire pump products, fire pumps can be divided into multi-stage and single-stage fire pumps.

    Multi-stage pumps have high efficiency, corrosion resistance, reliable operation and other properties, strong bearing capacity of the pump body, strong resistance to overload and more sensitive start. Ltd. introduces you to the relevant features of multi-stage pumps. First of all, Shanghai Xizhiquan multi-stage pumps have a compact structure, with small spacing between parts and small volume. The equipment runs smoothly, has a long service life and produces less vibration during operation, so the practical life of the equipment is correspondingly long.

    With its unique structure, the direction of the water inlet and outlet can be adjusted according to different needs, so it is suitable for various place environments. The direction of the inlet and outlet is horizontal, which reduces the number of bends in the pipeline connection, thus simplifying the pipeline connection and greatly enhancing the efficiency of the fire fighting system.

    The efficient operation of the multistage pump is used in many larger, more demanding fire-fighting locations. Its role is mainly to play a role in the fire fighting pipeline system to pressurise and send water, multi-stage pumps are not only suitable for all kinds of fire fighting systems, but also for industrial drainage, high-rise building water pressure supply, long-distance water delivery, water circulation pressure and other occasions.

    First, what’s a water pump? It’s a device used to transport liquid, pressurize the liquid, and make the liquid from the first liquid position to the high liquid position. The first water pump constructed by the Chinese is called” water windmill”. latterly, around 300 BC, the emergence of the” Archimedes screw pump” is more analogous to ultramodern pumps. In addition, the following introductory knowledge points are what you must understand.
    1. Centrifugal pump

    Centrifugal pump is the most common type of pump. In simple terms, the working principle of centrifugal pump is to rotate the impeller to drive the liquid under the action of centrifugal force. The liquid leaves the impeller and enters the volute. As the inflow passage of the volute gradationally expands, the fluid haste slows down, and the pressure rises continuously, and eventually it’s discharged through the conduit.
    2. Impeller
    The impeller is one of the main factors in the water pump, and it’s the core element that transmits mechanical energy to the liquid. The impeller is substantially divided into three types open type,semi-open type and closed type. The material conditions for the impeller are high, wear resistance is needed, and the manufacturing process is good.

    3. Cavitation

    Cavitation is the conformation of numerous bitsy recesses when the liquid connections the liquid under high- speed inflow and pressure, and gradationally expands into grottoes when serious, and cavitation frequently occurs in the impeller and pump covering.
