How to select a fire fighting pump? - Better Technology Co., Ltd.

The fire pump selection needs to take into account the influence of various factors. In general, the priority of these influencing factors in the fire pump selection is as follows.

(1) Impact analysis of fire pump selection operation reliability
As a fire rescue equipment for offshore oil and gasoline fields, the operational reliability of fire pump choice is the most essential design control factor for fire pump selection. Designers have to fully consider the geographical location around the fire pump, environmental conditions, system design of fire protection, emergency power supply, and so on. These conditions have a new great influence on the operational reliability of fire pump choice, and sometimes an affecting factor is possible. Reject a fire pump selection. Consequently , a good fire pump selection design should be a comparative analysis of all aspects impacting the operational reliability of the fire pump, to minimize the adverse factors affecting the reliability of the fire pump operation.

(2) Analysis of the influence of fire pump selection on the platform system
The design of fire pump selection should fully understand the emergency power supply system of the oil and gas industry and the situation of the normal power source system. Because the design of the fire pump not only has an effect on the equipment selection of the emergency power supply system and the emergency machine, but also the equipment choice of the emergency power provide system and the emergency machine. There is a mutual effect and mutual restraint relationship between them. Fire water pump selection should also follow the principle of system design optimization.
If the emergency load in the oil and gas field is really small, as well as the power load of the fire pump accounts for a big proportion of the emergency load, it directly influences the selection of the emergency machine. In this case, the vertical long-axis firefighting driven by the diesel powered engine should be chosen as much as possible. The pump avoids the use of motor-driven fire pumps to generate an unreasonable increase in the impact on the emergency system and the load on the emergency machine. If the emergency load in the oil and gasoline field is large, and the power load of the fire pump makes up a small proportion of the emergency load, but the difference within the efficiency of the pump straight affects the selection of different powers of the emergency machine, the reliability is satisfied, The submersible fire pump with high pump efficiency reduces the selection of emergency equipment power and optimizes the platform system.


(3)The fire pump selection consider the configuration of seawater lift pump
Generally, seawater lift pumps upon offshore oil and gasoline fields often use vertical long-axis fire pumps and submersible fire pumps. If the above two conditions can be met, the selection of the fire pump also needs to fully consider the equipment selection of the seawater lift pump, and try to achieve the consistency with the pump type and parameters of the seawater lift pump. In this way, not only the spare condition of the fire-fighting equipment is increased, the reliability of the supply of the fire-fighting water system is increased, but also the versatility of the spare parts during the production operation of the oil and gas field is facilitated, the management and maintenance are facilitated, and the maintenance cost and the service cost are reduced.

(4) Analysis of economic impact of fire pump selection
In the design of fire pump selection, the economic analysis should not only consider the initial equipment acquisition cost of the equipment, but also the operating costs, equipment maintenance costs, personnel service costs, etc. required for the future operation and maintenance of the equipment. In this way, it is possible to objectively analyze and evaluate its economics.
