Tailored 50GPM 6Bar ED Fire fighting Pump Set for Every Scenario

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.

In order to match the service cycle of the fire pump, the inspection of the diesel engine and the fire pump should be regularly checked, and the parts to be replaced or repaired should be adjusted and corrected in a timely manner. We need to check the fuel tank reserves and oil quality of the diesel engine fire pump every day; the usage of the battery; the cooling system, etc., the pump shaft, impeller, bearing, and the wear of the water pipe and filter screen of the water pump. (Diesel engines of different brands may be different, and should be checked and maintained according to the specific model and structure of the diesel engine).

Fire pumps are used to pump various liquids. They are ideal pumps and fire protection systems for building non-leakage, pollution-free civilized workshops and civilized factories. They are often installed on fire trucks, fixed fire extinguishing systems or other fire-fighting facilities for transportation Special pumps for liquid extinguishing agents such as water or foam solutions. Fire pumps are widely used in environmental protection, water treatment, fire protection and other departments.

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.

There is a combination equipment that uses diesel as fuel for firefighting, but it is usually used as a backup firefighting facility, because it can only be started automatically when the firefighting signal comes, and the electric water pump fails or the power supply is cut off, that is, the diesel engine firefighting pump set. It is very different from the electric fire pump in that it has its own independent power supply and storage system.

Learn how to choose the right fire pump for your building. Compare electric vs. diesel pumps, sizing, and NFPA 20 compliance to ensure fire safety.

Diesel fire pumps are available in various configurations, including horizontal split-case, vertical turbine, and end-suction pumps. Each type has its advantages and is suitable for different applications based on factors such as space limitations, flow requirements, and installation preferences. Consulting with a qualified engineer or fire protection specialist can help determine the most appropriate type of diesel fire pump for a specific application.

Building occupants should receive training on the location and proper use of firefighting equipment, including fire pumps. Regular drills and educational sessions contribute to increased awareness and preparedness during a fire emergency.
