product description

I. Cummins generator / generator advantages:

Excellent quality, low fuel consumption, low noise, high output power and reliable performance. Its reliable stability, economy, power, durability and environmental safety are welcomed by users at home and abroad. The Sino-US joint venture Dongfeng Cummins and Chongqing Cummins engines have small size, light weight, low fuel consumption, high power, reliable work, convenient parts supply and maintenance. The electronic governor is used to provide protection functions such as high cooling water temperature, low oil pressure, overspeed alarm and automatic shutdown.


Cummins diesel generators are officially authorized products of Cummins, with better performance, better quality and more guaranteed service among similar products, so they are welcomed by customers.


Product Overview of Cummins Generator / Generator Set

1) The design, production and testing of the generator set fully comply with the national standard GB / T2820-97.

2) Equipped with Cummins engine, advanced technology, reliable performance and long working life.

3) The generator excitation system can make the frequency fluctuation recover quickly when the unit is loaded at any instant.

4) The generator is designed with low power to make the waveform distortion under non-linear load extremely small, and it has good starting motor capacity.

5) Cummins provides quality assurance for a full range of products.

6) Cummins company builds a professional service network throughout the country, providing customers with 24-hour after-sales service and spare parts supply.


3. Cummins company profile

Cummins is the largest company in the world to design, produce and sell diesel engines and compressed natural gas engines. Cummins has invested more than USD 140 million in China, including Dongfeng Cummins Diesel Generator Set and Chongqing Cummins Diesel Generator Set. As the largest foreign investor in the Chinese engine industry, Cummins has eight joint ventures and wholly-owned manufacturing companies in China, of which Dongfeng Cummins produces B, C and L series diesel engines, and Chongqing Cummins produces M, N and K series diesel engines. The product complies with ISO 3046, ISO 4001, ISO 8525, IEC 34-1, GB1105, GB / T 2820, CSH 22-2, VDE 0530 and YD / T 502-2000 "Technical Requirements for Communication Diesel Generators" and other standards.


4. Cummins generator / generator technology introduction:

1. Cummins generator exhaust system

1) Use a hanger or bracket to support the exhaust pipe and supercharger

2) The bellows is strictly prohibited to be used as an elbow and to compensate for installation errors

3) For units over 200KW, use stainless steel bellows over 610mm.

4) The exhaust pipe laid horizontally is set with a slope of 0.3-0.5%, the slope is outdoor, and a drain valve is set at the lowest point.

5) When disposing the engine exhaust pipe, it is forbidden to use a pipe with a diameter smaller than the exhaust port.

6) If the exhaust pipe must be bent upwards, a drain plug should be set at the rising starting point.

7) When multiple generator sets are installed, special attention should be paid to the common exhaust pipe.

2. Cummins generator cooling system

1) The air inlet should be set on the generator side or on both sides of the generator. The area should be 2.2 times larger than the water tank area.

2) The area of the air outlet should be 1.5 times the area of the water tank, and shutters and wind walls should be installed at the air outlet.

3) The flexible air duct flange is used to connect with the water tank to absorb the displacement and vibration of the unit and prevent the transmission of noise.

4) The hot air must be discharged to the outside of the machine room through the air duct, and the cross-sectional area of the air duct should be smoothly transitioned from small to large. If there is a curve in the air duct, a deflector must be installed to reduce pressure loss.

5) When the ambient temperature is higher than the design temperature, consider reducing power usage.


Five, Cummins generator / generator standard configuration

Engine: Cummins 4-stroke diesel engine

Generator: Stanford / Marathon Brushless Alternator

Short circuit protection: MCCB air switch

Cooling system: On-line cooling water tank that meets the heat dissipation requirement of 40oC ambient temperature

Filter systems: Cummins oil, fuel and air filters

Accessories: exhaust elbow, bellows, muffler and other accessories


Installation of Cummins generators / generators

1. Cummins generator room design

1) The unit should be arranged horizontally. When restricted by the building site, it can be arranged vertically

2) When the machine room is adjacent to the control room, the generator outlet and cable trench should be close to the power distribution room.

3) The battery should be near the starter motor

4) The machine room should have sufficient fresh air inlets, hot air and exhaust ducts should extend outside, the air inlet should be set on the motor side, and the air outlet should be set on the water tank side

5) Machine room shall adopt comprehensive measures for unit noise reduction and machine room sound insulation

2. Noise reduction processing method of Cummins generator set

A. The unit is installed on the concrete floor:

1) A reinforced concrete base should be poured on the floor

2) The concrete base should pass the pressure test above 173KPa for one month.

3) The concrete base should be at least 150mm higher than the floor, and the extension of the unit chassis should be at least 150mm extended on each side.

4) "J" or "L" anchor bolts should be embedded in the cement base

B. The unit is fixed on the chassis fuel tank:

1) A shock absorber must be installed between the engine and the fuel tank

2) The structure and strength of the fuel tank must be able to withstand the static and dynamic loads of the unit

3) There must be a certain distance between the bottom of the fuel tank and the ground to facilitate maintenance

3.The unit is installed on the basis of vibration isolation
