What are the considerations for fire pump systems in research laboratories and R&D facilities?

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.

The diesel engine fire pump set has the characteristics of good starting performance, strong load capacity, compact and effective structure, convenient maintenance, simple and reliable use, etc. The generator set has maintenance functions such as speed limit, low oil level, repeated failed starts, high temperature, low oil level, and low battery voltage. At the same time, it can be connected with the customer’s automatic fire alarm system or the centralized control cabinet of fire-fighting facilities to establish a real-time monitoring function.

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.

In cold climates, fire pumps must be designed and installed to prevent freezing and ensure reliable operation in low temperatures. This includes using heated enclosures or pump rooms to keep the pumps and associated piping above freezing temperatures. Insulation and heat tracing can be applied to pipes to prevent water from freezing, particularly for outdoor or exposed piping. Additionally, anti-freeze solutions may be used in sprinkler systems to protect against freezing. Fire pumps in cold climates must also be tested and maintained regularly to ensure that all components, including heaters and insulation, are functioning correctly. Special considerations are also given to the type of fire pump selected, with diesel-powered pumps often preferred over electric ones in areas where power outages during winter storms are common.

The engine cooling system of the diesel engine fire pump adopts double closed-loop heat exchangers. The system has the advantages of high cooling efficiency and little impact on the ambient temperature of the pump room. The cooling water flow direction is controlled by a ball valve from the pump outlet pipe to the heat exchanger, so that the cooling water temperature of the machine body is between 85 and 95 °C. If the water temperature is too high, you can increase the opening of the ball valve, increase the heat dissipation capacity of the heat exchanger, and reduce the temperature of the engine cooling water.
