Submersible pumps are important equipment for pumping water from deep wells. When in use, the entire unit submerses into the water to extract groundwater to the surface, which is used for domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship load regulation, and can also be used for fountain landscapes. Hot water submersible pump is used for heating?...

Wenzhou Net NewsThe pump and valve industry is our city’sOne of the traditional pillar industries, it is an important area for strengthening the national industrial base. In order to accelerate the reconstruction of the city's pump and valve industry foundation and the improvement of the industrial chain, and create a globally competitive pump and valve intelligent manufacturing base, the Municipal Economic and Information Bureau and the Provincial Institute of Industry and Information Technology recently formed a joint research team to compile the "Wenzhou City "High-quality Development Plan for the Pump and Valve Industry" (hereinafter referred to as the "Development Plan") points out the direction for the future development of Wenzhou's pump and valve industry.

According to whether there is a power source, it is divided into: fire pumps without power source(referred to as pump),fire pump unit(referred to as pump unit).

1. Unpowered fire pumps can be classified according to the following rules

1. According to the use occasion, it is divided into: vehicle fire pumps, marine fire pumps, engineering fire pumps, and other fire pumps.

2. According to the outlet pressure level, it is divided into: low pressure fire pump, medium pressure fire pump, medium and low pressure fire pump, high pressure fire pump, high and low fire pump

3. Divided according to use: water supply fire pump,Stable pressure fire pump, foam liquid supply fire pump

4. According to auxiliary characteristics, they are divided into: ordinary fire pumps, deep well fire pumps, and submersible fire pumps.

Fire pumps achieve the purpose of increasing water pressure and transporting water through mechanical movement. Like other mechanical products, its work requires lubricating oil to provide lubrication, otherwise dry grinding will cause pump failure. As emergency equipment, some fire pumps do not work for a long time, so lubricating oil is particularly important for it.

According to the content of the "Technical Specifications for Fire Water Supply and Fire Hydrant Systems", today the editor will tell you about the installation requirements of the fire pump control cabinet.
The fire control room or duty room should have the following control and display functions. The fire control cabinet or control panel should be equipped with a manual direct pump start button connected through a special line.
The fire pump control cabinet or control panel should display the operating status of the fire water pump and pressure stabilizing pump, and should be able to display high and low water level warning signals as well as normal water levels of fire pools, high-level fire water tanks and other water sources.
When the fire pump control cabinet is installed in a dedicated fire pump control room, its protection level shall not be lower than IP30. When installed in the same space as a fire water pump, its protection level shall not be lower than IP55.
The fire pump control cabinet should be equipped with a mechanical emergency pump starting function, and it should be ensured that if a fault occurs in the control loop in the control cabinet, the fire pump will be started by a person with management authority. When the machinery is started in an emergency, the fire pump should be ensured to work normally within 5.0 minutes.

According to whether there is a power source, it is divided into: fire pump without power source (pump for short) and fire pump group (pump group for short).
