Silenced Diesel Pumpset Station.

Silenced Diesel Pumpset station JQS :   The silenced diesel engine pump, developed with advanced technologies, is used for emergency fire control and living water supply. With large flow and high lift, it is suitable for long-distance water delivery with the large flow. It has higher efficiency with a double channel design. Equipped with a vacuum-assisted system, it can achieve self-suction without irrigation. Characteristics:1. 1m noise measured 65dB(A)-85dB(A);2. Silenced diesel engine pump, has a compact structure, small;3. The vibration absorbed, to reduce vibration and noise;4. Noise absorbed material-made cover, to reduce noise;5. Noise absorbed compound silencer reduces noise;6. High-efficient noise-off inlet channel;7. Big-capacity fuel tank;8. Cap plate, easy to maintain.Conditions:1. Altitude:≤2500m2. Ambient temperature:-25~55ºC3. Relative humidity:9~95%4. Earthquake: 7 degree5. Flow range: 50-700(L/S)6. Head range: 32-600m7. Diesel engine power: 18-1100KW8. Media part materials: cast iron, graphite cast iron, stainless steel, cast copper.Silenced diesel engine pump:1. automatic start: when receiving fire/piping network/power off/other start signals, in 5s, automatic start with a full load;2. automatic charging: the storage can carry out automatic charging by industrial power supply or diesel charging motor;3. automatic warning: automatic warning for diesel engine low oil pressure, high water temperature, ultra-speed;4. automatic preheat: for emergency;5. Direct coupling: under 360kw, diesel engine pump, innovative, flexible shaft couples, direct coupling.Technical Parameter :   Flow80 - 3600 m3/h Head 10 - 210 m Speed 980 - 3000 RPM Power11 - 1600  kWCaliber 150 - 600 mm Start, running and stop Start1. First of all, pour water into pipes, to make the pump and inlet pipe filled with water. The pipes shall be sealed, no air leaked. (no-water inside start is forbidden) 2. Close globe valve and cock on outlet pipe, to reduce start currency.3. Rotate the rotor by hand, lubricate the bearing and check the pump impeller, seal the ring, if it cannot rotate, you shall not start.4. Try to start, motor rotation direction shall be as same as the arrow direction on the pump. 5. When the rotor works normally, open gradually the outlet globe valve, adjust for the work conditions required.Running1. Observe the reading in meters, keep it running around the flow and head shown on the nameplate.2. Regularly check, motor currency value shall not exceed rated currency value.3. Pump bearing temperature shall not exceed 75ºC, and shall not be 35ºC higher than ambient environment.4. To start, loosen the stuff cap. Adjust later when started.5. In case of fragile component abrasion, replace in time.6. When any abnormal happens, immediately stop and check.Stop1. Close the globe valve on the outlet pipe, close the vacuum gauge cock.2. Stop the motor, and close the pressure cock.3. In Winter, drain the liquid in the pump completely to avoid frozen cracks.4. When you will not use it for a long time, uninstall the pump, clean, and lubricate Troubleshooting  FaultCauseSolutionThe 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 gauge1, bottom valve closed or jammed 2, Too great water suction resistance 3, filter jammed 1, check bottom valve2, replace water suction pipe3, clear off the filterPressure gauge works, no water outcome1. Great outlet water pipe resistance2. Wrong rotation direction 3. Outlet pipe valve closed4. impeller jammed 1. check or shorten water pipe 2, check the motor, adjust 3, open the valve and clear off the impellerCannot reach designed flow1. 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 depth3, uninstall and clear off 4, replace seal ring Great pump power consumption1. Stuff tightened, overheated 2. Great flow 3. Collision between rotor and case 4. Pump shaft bearing abrasion 5. Pump shaft misplaced1. loosen slightly2. reduce globe valve opening3. 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 etching1. Uninstall and clear off 2, replace 3, increase opening 4, adjust5, replace  6, change suction inlet position  Borra Technology Co., Ltd.Borra Technology co., Ltd., founded in 1995, owns a top-rank design, production, sales, and service team, and modern production lines, to manufacture various self-priming pumps, movable diesel pumps, diesel Self-Priming dirt drain pumps, diesel fire pumps units, diesel mini pumps Certificate : Services:1.
