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.

With the advent of the information age, people have higher requirements for the quality of life, and fire safety is particularly important for high-rise buildings. The state attaches great importance to fire safety work. All workplaces require us to be equipped with fire safety facilities, and fire pumps are necessary water intake equipment for fire infrastructure. The commonly used fire pumps in our country are electric fire pumps and diesel fire pumps. The difference between the two is that the electric fire pumps need a power system. If the diesel engine fire pumps can be started at any time to fill the position of the original electric fire pumps.

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.

The function of the diesel fire pump is very powerful. We can set the control time during use, for example: preheating in advance, pre-lubrication or timing start. The use of high technology has made some complicated and time-consuming things easier. The preheating setting in advance has greatly reduced the preparation time for rescue, allowing firefighters to rescue at the first time. In the face of disasters, time is money, time It is life.

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.
