DJ (diesel engine + jockey pump) Fire Pump Set

Fire pump sets are often required when the local water system cannot provide sufficient pressure to meet the design hydraulic requirements of the fire sprinkler system. This typically occurs in multi-story buildings or systems that require relatively high terminal pressures at fire sprinklers in order to release large volumes of water, such as storage warehouses. A fire pump is also required if the water supply is provided from above-ground or underground storage tanks.

The EEJ fire pump set is composed of two electric pumps + one jockey pump. The motor of the electric pump is directly connected to the ISW pump head. The jockey pump adopts CDL pump, adopts high-quality NSK bearing and wear-resistant mechanical seal, which is suitable for any emergency firefighting occasion. . Products can be customized according to their own needs.

Fire pumps have a wide range of uses. In addition to providing water for fire-fighting pipeline systems, they can also be used in industrial water supply. Fire pumps can also be used in urban water supply and drainage systems. There are other relatively long-distance water supply work, such as heating boilers, bathroom boilers, hot and cold water circulation pressurization of multi-stage fire pump boilers, etc.

The Fire Pressure Stabilization Equipment, coupled with the CDL Vertical Multistage Fire Pump, offers a comprehensive solution to elevate fire safety measures. This powerful combination ensures a consistent water pressure for effective fire suppression. By incorporating pressure stabilization technology, this system guarantees an uninterrupted fire water supply, efficient water distribution, and reliable operation of fire hydrants and sprinkler systems. With advanced infrastructure and the ability to maximize firefighting capabilities, this configuration significantly enhances overall fire safety standards. Investing in fire pressure stabilization equipment is a proactive step towards ensuring superior fire protection and providing peace of mind in critical situations.

First of all, check whether the oil level is normal and cannot reach the oil mark line on the normal surface. If it is not, we must replenish it in time, but remember one thing, it cannot exceed the amount of the oil quantity indicator line.

Secondly, check the radiator. The water is appropriate. If it is not added in time, the water that needs to be added must be clean water, as long as it is clean water, or tap water is fine. Why not use groundwater, because impurities in groundwater can easily form scales in the water tank, which affects the cooling effect and is also prone to failure. In winter, we drive to preheat the car, add coolant to the car, and the fire pump is no exception. The weather in the north is very cold, so add the coolant to the fire pump according to the actual temperature.

Finally, check the installation of each part of the fire pump, such as whether they are stable, the connection between the screw and the screw, if there is any looseness, tighten the screw in time. To clean the fire pump, soak a canvas or dry cloth and wipe slowly on the body or on surfaces made of grease or dust.
