Structural features and functions of diesel engine fire pump

The number of impellers is different, and the head is also different: Generally speaking, a single-stage pump has only one impeller, while a multi-stage pump has two or more impellers, which enables it to suck water many times and segment it. processing, which greatly increases the lift. Therefore, under the same medium flow, the lift of the multi-stage fire pump appears higher.

All places need to be equipped with fire-fighting facilities, and fire pumps are the water intake equipment for fire-fighting facilities. At least one or two fire pumps are equipped. Our commonly used fire pumps are electric fire pumps and diesel engine fire pumps. The difference between them is that electric fire pumps require power systems. supply. In the event of a power failure, the diesel engine fire pump can be started at any time to make up for the original position of the electric fire pump.

The diesel engine fire pump has the characteristics of good starting characteristics, strong overload capacity, compact and reasonable structure, convenient maintenance, simple and reliable use, etc. The unit is equipped with protection functions such as overspeed, low oil pressure, three start failures, high water temperature, low oil level, and low battery voltage. Diesel engine fire pump is composed of diesel engine, chassis, cooling water tank and fan, high elastic coupling, water pump, diesel tank and control panel and other equipment. The diesel engine fire pump is directly connected with the diesel engine through a highly elastic coupling or a diaphragm coupling, and is installed on a common channel steel chassis.

Vertical turbine pump is a kind of centrifugal water pump, which is used to deal with non-corrosive clear water at normal temperature. The main working part is the impeller, which can generate centrifugal force through high-speed rotation to achieve the function of lifting water. In a group of cases, it only needs to match the head, flow rate, power and other requirements. There will be no problem.

The main advantage of the hand-held diesel fire pump is the high lift, which can reach 90 meters. It is generally used for fire emergency fire prevention, forest emergency fire prevention, and factory fire protection. When the diesel engine fire pump is working, the auxiliary impeller is together with the pump main shaft Rotating, the liquid in the auxiliary impeller will also rotate together, and the rotating liquid will generate an outward centrifugal force. On the one hand, this centrifugal force resists the liquid flowing to the mechanical seal, reducing the pressure at the mechanical seal. On the other hand, it prevents the solid particles in the medium from entering the friction pair of the diesel engine fire pump seal, reduces the wear of the mechanical seal grinding block, and prolongs its life. The auxiliary impeller of the diesel engine fire pump can not only play a sealing role, but also reduce the axial force. In the diesel engine fire pump, the axial force is mainly caused by the pressure difference force of the liquid acting on the impeller and the gravity of the entire rotating part. The direction of action of these two forces is the same, and the resultant force is formed by the addition of the two forces.

As a fixed fire extinguishing equipment, diesel engine fire pump has been widely used in fire diversion, especially in emergency situations such as no power supply or abnormal power supply, other diesel engines can also be equipped as power engines according to the needs of users.
The diesel engine fire pump has automatic, manual and fault self-checking functions. It can monitor the working state of the whole process, restore the function of failure start, automatic pre-lubrication and automatic restart of preheating, so that the equipment start-up is safer and more reliable. It has the functions of central control room remote control, remote control and field bus connection. The battery is fully automatic floating charge (constant current, constant voltage, trickle charge) mode to ensure that the battery is in a standby state at any time. Diesel engine fire pump is easy to use, equipped with remote instrument and instrument, which can be connected to the control center as needed, easy to install and use, and easy to maintain.

The pump that supplies water to some sprinkler systems is called a fire pump. These pumps can be powered in several ways: namely diesel and electric. The water source connected to the pump inlet can be a static water source (i.e. lake, reservoir, tank) or a pipe from an underground public water supply.

Portable fire pump is mainly composed of engine, water supply system and hand lift. The engine is the power. Most of the engines used in portable fire pumps are automobile engines, because automobile engines have the characteristics of high power, light weight, simple structure, easy to use and maintain, and fast starting. The air supply system is the working part of the portable fire pump, and the hand lift is the support of the whole machine. When using, pull out the handle horizontally to lift the pump.

Fire pumps are typically activated automatically when a drop in water pressure is detected in the fire protection system. This drop in pressure can be sensed by a fire detection system or a flow switch.
