Control system and application of fire pump group

1. Electric fire pump: various end suction pumps and split pumps.
2. jockey pump: vertical, small flow, higher lift than electric or diesel pumps.
3. Control panel: Automatically control the water pump with overload and overcurrent protection.
4. Accessories: suction pipe, discharge pipe with flange, battery, gate valve, check valve, flexible expansion joint, pressure switch, pressure gauge, base, etc.

Diesel engine fire pumps can be divided into self-priming, centrifugal and double-suction types. Self-priming pumps are widely used in urban flood control and emergency rescue. Centrifugal pumps are divided into single-stage centrifugal pumps and multistage centrifugal pumps.

The diesel engine fire pump set has good starting performance, compact structure, humanized design, convenient maintenance, simple and convenient use, and high degree of automation. It is a very good fire pump. The diesel engine fire pump has the advantages of long head and wide application range, and can meet the fire water supply in multiple places such as warehouses, docks, airports, power plants, liquefied gas stations, and petrochemical industries.

Floating impeller axial force tone- balancing device
The balancing slice device has two gaps, the radial gap behind the impeller and the axial gap of the balancing slice, because of these two gaps, the balancing slice can automatically acclimate the axial l gap to achieve automatic balance of axial force, and the tableware rotor is in a floating state.

The principle of the balance plate is scattered to the impeller, the impeller back mouth ring radial concurrence below the axial concurrence, this device that’s the same as the balance plate, the conformation of two gaps, only in a different position. Because the impeller has these two gaps to round each other, so that the impeller can also achieve automatic balance of axial forces.

Fire Pump Packages
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.
Fire pump package is required to comply with Local Civil Defense Authority regulations and International Codes of Practice e.g. National Fire Protection Association (NFPA).

Types of pumps used for fire service include: end suction, horizontal split case, vertical split case, vertical inline and vertical turbines.

As the name suggests, fire pumps are used in fire protection. They are divided into different types according to different classification methods. They are fully sealed and leak-free. They are used in environmental protection, water treatment, fire protection and other departments to pump various liquids. They are created The ideal pumps for non-leakage, civilized workshops and civilized factories are similar to the pumps for fire protection systems, but the head and flow are different.

Electric fire pumps are mainly used for fire-fighting water supply in high-rise buildings, with a wide range of head and flow. Basically, the needs of most users can be met. The operation of electric fire pumps is relatively simple. The main function of electric fire pumps is water supply. If Insufficient water output will affect emergency use, so everyone should choose a matching and suitable fire pump model.

There are many types of fire-fighting equipment. Fire hydrants and fire extinguishers are the most common types. The other is the fire pump, which is the heart of the fire-fighting system and plays an important role in pressurizing the fire-fighting system. Among the numerous fire pump products, fire pumps can be divided into multi-stage and single-stage fire pumps.

Fire pumps are mainly used for pressurized water delivery in firefighting system pipelines, and can also be used in industrial and urban water supply and drainage, high-rise building depressurized water delivery, long-distance water delivery, heating, bathrooms, boiler cold and warm water circulation pressurized air conditioning refrigeration system water delivery and equipment matching, etc.

Common issues with firefighting pumps include priming failures, leaks, clogs, engine or motor problems, and inadequate water supply. Troubleshooting steps may include checking for obstructions, inspecting hoses and connections, verifying fuel and oil levels, and consulting the pump’s manual for troubleshooting guidance.

ZJBetter provide three types of fire pump system, such as diesel engine fire pump set, electric driven fire pump set, EDJ fire pump set.

The electric fire pump is manufactured with good structure and workmanship. It has a wide range of performance, and is easy to use and operate for a long time. The electric fire pump is aimed at various fire water environments, so the selection should also be based on the actual demand environment, performance parameters, etc.

Fire pumps are part of the water supply to a fire sprinkler system and are powered by electricity, diesel or steam. The pump inlet is either connected to a public groundwater supply or to a static water source (e.g. tank, reservoir, lake). This pump provides higher pressure water flow to sprinkler system risers and hose risers.

Fire pumps should be tested on a regular basis according to national and local regulations. Common testing frequencies are monthly, quarterly, annually, and five-yearly, with different tests conducted at each interval.

The DJ fire pump set consists of a pump connected to the diesel engine, jockey pump, pressure vessel, controller for manual or automatic operation of the system and standard accessories mounted on the base.
