Fire pump acceptance is a critical process that involves passing national testing standards. When the fire pump arrives at the construction site, it must be accompanied by a valid fire inspection report. Therefore, the quality requirements for fire pumps are quite stringent. Their performance parameters and technical specifications must comply with relevant industry standards, featuring high efficiency, low operational noise, excellent anti-cavitation performance, a rational design, and a long service life.
In this article, I will introduce you to the model selection and maintenance aspects of fire pumps. Fire pump maintenance is essential to ensure reliable operation. Before assembly, all components should be thoroughly cleaned, and technicians should familiarize themselves with the design drawings and product documentation. It is important to verify that the fire pump model matches the product certification, production license, test report, and assembly manual. Cleaning should follow the assembly sequence, and appropriate grease should be applied where necessary. Any parts that have already been installed should be checked for cleanliness and integrity. If not required, they should be cleaned accordingly.
During the assembly process, each component must be inspected for dimensional accuracy and surface condition to ensure they meet the assembly requirements. Proper assembly is crucial for the pump's long-term performance and reliability.
When selecting a fire pump, it's important to consider its role in maintaining the required pressure for both sprinkler and hydrant systems. The fire pump ensures adequate water supply during emergencies, making it a key component in fire protection systems. In many cases, it functions as a booster or pressure regulation pump, especially in automatic sprinkler systems.
Several factors influence the flow rate of a fire pump. First, the type of fire protection system determines the required water volume—sprinkler systems depend on the number of sprinklers, while hydrant systems rely on the number of fire hydrants. Second, the presence of an air pressure water tank affects the pump's flow requirements. Without an air pressure tank, the pump’s flow is calculated based on the maximum water demand from a single nozzle or hydrant. However, if an air pressure tank is installed, it helps maintain system pressure and supplement water, so the pump only needs to meet the pressure tank’s flow requirements. In such cases, the regulator pump flow should be calculated based on the total volume of the air and water tank, as well as the water volume inside the tank. The pump should provide at least 1.2 times the maximum hourly water demand of the pipeline network when the tank is at average pressure.
These are some of the key considerations when selecting and maintaining fire pumps. We hope this information helps our customers better understand the importance of proper model selection and regular maintenance for optimal fire protection performance.
Pulse Controller
Pulse Controller is a pulse jet bag filter control device in cleaning system, its output signal to control pulse jet valve, blow compressed air bag sequential cleaning, so dust remains in the design within a predetermined range, in order to protect the processing power and dust collecting effect.
1. Controller outputs an electrical signal duration, called pulse width.
2. Controller output time interval between the two signals, called pulse interval.
3. The control device outputs an electric signal to complete a cycle, the time required for the pulse cycle is called.
Features:
1. Chassis: exquisite style PC works transparently bare chassis, with the appearance of new, sealed, dust-proof effect, to meet the modern international trends.
2. Movement: using chip technology to control the pulse output, pulse width, pulse interval and the number of output gates can be arbitrarily set according to the desired site, the realization of intelligent control.
3. Power supply: imported power components, thus ensuring the reliability of the machine, in harsh mining conditions of long-term stability.
4. Differential pressure control: can be connected with the second-tier passive differential pressure transmitter ,4-20mA standard current signal to the dust resistance remains within the set range, to ensure that in addition to the hubbub of the economy.
5. Wiring: Convenient and flexible plug-in terminals.
