Diesel High-Pressure Pump JQD :
The diesel engine fire pump set produced by this company is researched and developed in accordance with the national standard GB6245-2006 "Fire pump performance requirements and test methods" and the American Fire Protection Association standard NEPA20 "Centrifugal fire pump installation" and other standards. At the same time, it is based on market demand and uses When a fire occurs in a building, the power supply system is faulty, and the electric fire pump cannot be put into operation, the diesel emergency fire pump will automatically be put into operation to ensure the normal operation of fire fighting and extinguishing work to ensure the safety of life and property.
Application
This pump is applied in pumping freshwater, seawater, river water, corrosive water, impurity water, dirty water, etc. Such as
1. Irrigation
2. Fire fighting
3. Industry water
4. Mine water pump
5. Transport water with salt or any other impurity things
6. Marine

Pump Construction
Casing/impeller:cast iron,stainless steel,copper,bronze,
Shaft: carbon steel 45#, stainless steel
Mechnical seal:graphite/silicon carbide/tungsten carbide
Advantages
1. Directly coupled, vibration proof, and low noise.
2. Same diameter of inlet and outlet.
3.C&U bearing, which is the most famous brand in China.
4. Circulating flow cooling ensures the mechanical seal's long life.
5. Small foundation is required that will saving construction investment by 40-60%.
6. Excellent seal that is no leakage

Fault | Cause | Solution |
The pump cannot suck water, pressure gauge & vacuum gauge vibrating | 1. Insufficient water pouring 2. Leak between pipe and meter 3. Suction is too high |
1, check a leak in the bottom valve. 2, Tighten the leaked part 3, reduce suction |
The pump cannot suck, high vacuum is shown in the vacuum gauge | 1, bottom valve closed or jammed 2, Too great water suction resistance 3, filter jammed |
1, check bottom valve 2, replace water suction pipe 3, clear off the filter |
Pressure gauge works, no water outcome | 1. Great outlet water pipe resistance 2. Wrong rotation direction 3. Outlet pipe valve closed 4. impeller jammed |
1. check or shorten water pipe 2, check the motor, adjust 3, open the valve and clear off the impeller |
Cannot reach designed flow | 1. air sucked 2. Water level drops, submerged depth is not enough 3. impeller jammed 4. rotor torn and worn |
1, check leak part and clear off 2, prolong water inlet pipe, increase the submerged depth 3, uninstall and clear off 4, replace seal ring |
Great pump power consumption | 1. Stuff tightened, overheated 2. Great flow 3. Collision between rotor and case 4. Pump shaft bearing abrasion 5. Pump shaft misplaced |
1. loosen slightly 2. reduce globe valve opening 3. adjust 4. replace bearing 5. replace or adjust |
Great pump vibration | 1. impeller partially jammed 2. impeller damaged 3. little flow 4. non-concentric between pump shaft and motor. 5, bearing damaged 6, gas etching |
1. Uninstall and clear off 2, replace 3, increase opening 4, adjust 5, replace 6, change suction inlet port |
