From the operation of the fire pump, it is not difficult to see that its operation rate is fast, under the action of pressure, its operation process is very smooth, its main standby switching process is controlled by signal:
1, current signal control method: through the feedback of the motor current signal of the water pump, to judge whether the fire pump is working. When the motor short circuit (power failure), the current is too large, the power automatically switches to the motor of another pump set, stop the work of one pump, start the work of the other pump.Fire Fighting Pump
2. Pressure signal control method: the electric node pressure gauge is set on the outlet main pipe of the fire pump, and the switch between the main and standby pumps is judged by the signal of the pressure gauge. When the control box receives the action instruction, start either pump immediately. If the pressure indicated by the pressure gauge of the electric node after the pump works fails to reach the set pressure value, the control box will automatically switch to another pump to start the work.
Fire Fighting Pump through the signal control method, to achieve its main standby switching process, improve the efficiency of the use of equipment, switching back and forth, usually in multiple pumps can achieve this function.
The difference between submersible pump and self-priming pump Do a good job before starting the fire pump preparation fire pump self-test method comparison of fire pump does not pump the reason and solution fire pump power consumption reduction secret
Fire pump is really good to use, high efficiency, easy to use, its use can not be separated from the mutual cooperation of the components, such as the import filter, what is the necessity of installing it?
1, if the fire Fire Fighting Pump is transported at room temperature will solidified medium, in the selection of filter, must have the jacket insulation function, in order to effectively play the filtering effect, known as the imported insulation filter;
2, ordinary filter in use for a period of time, must be opened the sewage outlet, discharge the impurities left inside, if you want a simpler and more convenient sewage, can choose a filter with backwashing, is the import of automatic backwashing filter;
3. If the environmental temperature of the fire pump changes greatly, or the preloading force of the fire pump is large, the filter with telescopic can be selected to protect the impact force brought by the thermal expansion and contraction of the pipeline, and the length can be adjusted in the installation, with the import telescopic filter;
4, small diameter, low pressure, corrosive medium pipeline occasions, generally use internal thread connected check valve, with imported internal thread filter;
Therefore, in order to achieve the effect of sewage, it is necessary to install imported filter, improve efficiency, pump is widely used in life, the above content can be used in practice.
