Electric Diesel Jockey Pump Set-ZJBetter EDJ Fire Pump Set

Problem one lower water or no water
1, electric pump reversal will lead to the pump doesn’t produce water.
2, the pump can’t normal water into the same can’t be water, check whether the water bay or check stopcock is blocked or stuck, pumping pipe if there’s a leak will also affect the water into the water.
3, the pump internal corridor of the wear and tear or connection out, check the pump and motor coupling wear and tear, loose and impeller is worn.

Problem two ：
1 、 Check the power force as described over, including connectors, switches, fuses,etc.
2. Check whether the impeller in the pump is jammed by foreign objects
3. A burnt motor will also affect the launch of the pump.

Problem three the water affair is big for a while and small for a while
1. still, the lack of depth down the well may beget this problem, If the pump is a submersible pump.
2. The inflow rate of the pump is too high and needs to be replaced with a suitable pump.

In the fire fighting pipeline pump, according to the different installation methods can be divided into vertical fire pumps and horizontal fire pumps, many people have questions about these two common pumps, what is the difference between the two? Shanghai Xizhiquan will explain the difference between horizontal and vertical pumps.

Obviously, different installation methods take up different space. Vertical pipeline pumps are installed vertically, covering a relatively small area, and vertical fire pumps do not require a foundation, while horizontal fire pumps need to be equipped with a base.

According to the different structures of the two pumps, it can be concluded that there is also a certain difference in the ease of maintenance of the two types of fire fighting pipeline pumps. The impeller of the vertical fire pump needs to be dismantled from top to bottom, which makes maintenance more difficult; the horizontal fire pump only needs to have the inlet pipe removed so that the impeller can be overhauled, which is relatively simple.

Due to the different inlet and outlet pipe directions, the pipeline connection between vertical and horizontal is also different. As the vertical pump is a bottom-up structure, while the horizontal fire pump is longitudinally arranged on the base, so the motor of the vertical pump and the pump body are connected in the form of sub-mouth connection, while the horizontal pump needs to use couplings to connect with the motor, and the horizontal pipeline pump needs to be corrected regularly.

Fire pumps can be powered by various sources, including electricity, diesel engines, and, in some cases, natural gas. The selection of a power source depends on factors such as reliability, availability, and the specific requirements of the facility.

Electric fire pumps are commonly used in urban areas with a stable power supply. They are efficient and can start automatically in response to a fire alarm signal. In contrast, diesel-powered fire pumps are reliable in areas with inconsistent power availability, as they can function independently. The choice of power source should align with the facility’s operational conditions and the need for uninterrupted fire protection.

Fire pump package comprises a combination of electric motor driven pump, diesel engine driven and electric motor driven jockey pumps that supply for fire suppression systems.

Common Causes of Fire Pump Motor Failures:

Electrical Issues: Faulty wiring or power supply problems can lead to motor failure.
Overheating: Insufficient cooling or blocked ventilation can cause overheating.
Mechanical Failure: Worn bearings or misalignment can result in motor damage.
Lack of Maintenance: Neglecting routine maintenance can lead to premature failures.
Corrosion: Exposure to moisture and chemicals can damage components.
