Diesel engine fire pump is a common fire fighting equipment, especially suitable for use in places without electricity supply. The diesel engine fire pump uses a diesel engine as a power source to convert the work of the pump into hydraulic power to achieve a certain flow and pressure. It is mainly used in building fire protection, engineering fire protection, water source fire extinguishing and other fields.

Learn how to read fire pump performance curves to evaluate flow, pressure, and efficiency for selecting the right pump and ensuring optimal fire protection.

Multi stage pump refers to a pump with two or more impellers, which can absorb and press water in stages and stages, so as to lift the water to a very high position. The lift can increase or decrease the number of stages of pump impellers according to needs; When the single-stage pump head needs to be equipped with two-stage motors, the multi-stage pump can be equipped with four-stage motors by increasing the number of impellers, which can improve the service life of the pump and reduce the noise of the unit. When the actual required lift of the pump is less than 125 meters, the selection of a single-stage pump or a multi-stage pump can be comprehensively considered according to the area of the pump room, the pump price (the price of a multi-stage pump is generally higher than that of a single-stage pump) and other factors.

The diesel engine fire pump can form an automatic water fire water supply system with electric pumps and jockey pumps, and can be linked with the fire control center.
When the diesel engine fire pump set receives the starting command, if the mains power is cut off, the automatic control cabinet of the diesel engine will immediately send a start signal to the starting motor of the pump set, start the motor, start the diesel engine at idle speed, and then gradually adjust the throttle to accelerate the diesel engine until Rated speed. The control system will automatically monitor the operation of the diesel engine, such as the oil pressure, oil temperature, speed of the diesel engine, outlet pressure of the water pump, etc., and determine whether the diesel engine starts normally through automatic monitoring. If the start fails, the control system will send a restart signal, and if the three starts fail, the automatic control system will send a failure alarm. When the diesel engine fire pump set receives a signal that the pressure of the pipe network is restored or the mains power is restored to normal, the pump set will quickly slow down and stop automatically after monitoring the idle position for a period of time.

Intelligent linkage fire pump equipment has the advantages of automatic response, remote monitoring, independent diesel drive and stable water supply. It is widely used in modern smart building fire protection systems to improve the efficiency of automated fire extinguishing response and the building safety guarantee capability.

There are numerous ways to maintain fire pumps and water pumps. The following styles are more effective. You can use them for reference
System 1 The installation of the pump set should be accurate and dependable, and there should be no egregious vibration duringoperation.However, or the bearing is hot to the touch( the temperature is advanced than 60 °C) and the water seepage in the seal of the pump shaft is further than 60 drops per nanosecond, the cause must be set up out and the fault should be excluded in time, If the pump makes abnormal noise when pumping water.
the
system 2 Screws that are squinched daily, similar as packing gland screws, irrigation entrapments,etc., should be disassembled with a suitable wrench and a reasonable necklace. You can put some slicking oil painting on it or wipe it regularly with an oil painting cloth to help rust; if the water drain screw isn’t used constantly, it’s easy to rust, so after buying a new water pump, you should first wind the water drain draw, and apply some machine oil painting and white lead oil painting on the screw thread, Change the new oil painting two or three times a time in the future.
the
System 3 If the pump is waxed with machine oil painting, the slicking oil painting should be replaced once a month; if it’s waxed with adulation, it should be replaced every six months. It should be noted that the water pump uses calcium- grounded grease, and the motor uses sodium- grounded grease, and they shouldn’t be used inaptly. Because sodium- grounded grease is hydrophilic, it’ll emulsify into froth and dissipate when it encounters water on the pump, while calcium- grounded grease is hysterical of high temperature, so it’s easy to melt when the temperature rises when used on a motor.

system 4 Don’t pump water with too important beach, so as to avoid unseasonable wear and tear of the impeller, mouth ring and shaft, and try to help water deficit operation. Running without water will damage the water seal, and the water pump is prone to water leakage or indeed no water.
System 5 After the irrigation and drainage season is over, the water pump should be precisely gutted and auditedimmediately.However, they should be repaired or replaced in time, and the corridor that should be waxed should be filled with suitable oil painting; Stylish stored in a dry place, If any damaged or misshaped corridor are set up to be unworkable.

What kind of terrain to choose what kind of water pump

This problem, in short, is the selection of water pumps. The following are the applicable way for you to choose water pumps from zjbetter. I hope they can help you choose water pumps and help you better. Choose the water pump that suits your design.
1. Confirm the use terrain
First understand the terrain in which the outfit is used, including temperature, moisture, air pressure, air cattiness, dustproof and leakproof conditions, and the position of dangerous areas.
2. Confirm operating conditions
Refers to the liquid face pressure( absolute) on the suction side of the liquid, the liquid face pressure on the discharge side, intermittent or nonstop work, fixed or mobile position, and the convenience of installation and conservation.
3. Confirm the nature of the medium
Medium temperature, viscosity, density, impregnated vapor pressure, solid flyspeck periphery and content, gas content, cattiness, volatility, trap, toxin.
4. elect the material of the pump bathe corridor
According to the physical and chemical parcels of the pumped medium above, the material of the inflow- passing corridor is determined.
5. Determine performance parameters
The performance parameters of the water pump can be determined by computation, analogy, test and other styles.
6. Determine the installation type
The installation of the channel is determined by the layout of the channel and the installation point, and there are direct connection, perpendicular and other types.
8. Determine the number of pumps
In general, spare pumps, especially fire pumps, are set up, and the number of pumps is named according to different situations.

High-lift deep well fire pump units are designed for large-scale projects and feature deep well water intake, high-pressure long-distance water supply, and stable operation. They are suitable for fire protection systems in industries, ports, and high-rise buildings, providing reliable and efficient fire water supply solutions.

The pump casing of the electric pump of the fire pump set can be made of cast iron or stainless steel, the impeller can be made of copper impeller, the flow head, pressure or other parameters of the diesel pump are the same as those of the electric pump, and the diesel engine is connected to the pump head through a coupling. The jockey pump is a vertical pump, and its technical parameters are different from those of electric or diesel pumps. Generally, the lift is higher than that of electric and diesel pumps, and can be customized.

The jockey pump of the jockey fire water supply system must be kept running at ordinary times to maintain the pressure of the pipe network. When a fire occurs, it should still be able to run for a period of time until the main fire pump is started. It must be set according to the main and standby pumps. pressure pump. Due to the need for the stabilizing pump to keep running, energy is wasted, and the stabilizing pump is in working condition for a long time.
