On March 22, 2011, Cummins demonstrated to the customers of Chinese oil and gas fields for the first time at the 11th China International Petroleum & Petrochemical Technology and Equipment Exhibition (CIPPE) to meet the first, second and third stage emission standards of Europe and the United States (Tier 1/Tier). 2/Tier 3) 15 liter, 19 liter, 60 liter high horsepower engine with 375 to 3,000 horsepower, and the new QTR series gearbox for the oil and gas field fracturing market.
Compared with traditional gearboxes, Cummins QTR series gearboxes adopt a new design concept of dual clutches, which results in higher transmission efficiency, faster shifts, smoother shifts, and better reliability and durability. Once launched, the Cummins QTR series gearboxes are available to customers of oil and gas fields. highly anticipated. In 2011, Cummins will introduce the QTR2500 (2500 hp) and QTR3000 (3000 hp) products to the Chinese market. Customers can either purchase it separately or package it with Cummins 50-liter QSK50 engines or 60-liter QSK60 engines.
Cummins is a leading manufacturer of diesel and natural gas engines, providing advanced technology, reliable, durable, highly efficient fuel economy, clean and environmentally friendly diesel engines, natural gas engines, and oil drilling, cementing, oil recovery, workover, fracturing, and natural gas compression. Generator set. With more than 500 Cummins distributors and more than 5,200 distributor locations in 190 countries and regions, Cummins provides a full range of parts and after-sales support to customers around the world.
Highlights in Highlights: Cummins QTR Series Transmission
Over the past 20 years, Cummins has developed a series of engine products that meet the demand for tough oil and gas operations. In the new stage of global oil and gas exploration and development, Cummins enhanced the comprehensive competitiveness of Cummins in the oilfield market by introducing a complete power system: a durable engine + an efficient gearbox to meet the new demands of the market.
The QTR series gearbox is the first product in the industry dedicated to oil and gas field applications and meets the high requirements of fracturing equipment. Its unique dual clutch technology and synchronized shift design were first applied to large horsepower fracturing equipment and was a major breakthrough in the application of DaMali Oilfield. This design eliminates power interruptions when shifting gearboxes in the past, achieving smooth, fast shifts and providing constant torque over the operating range.
As an industry-leading new design and new product, Cummins QTR series transmissions do not use the torque converters commonly found in conventional transmissions, reducing the overall complexity of the system, avoiding common failures caused by torque converters, and improving the system. The reliability extends the service life. At the same time, this design also improves the thermal efficiency and mechanical efficiency of the system and achieves the effect of saving fuel and reducing emissions.
Through extensive consultation with customers, Cummins has also developed an industry-first electronic control test mode for the QTR series transmission. In this mode, the operator can control the output shaft rotation speed in a limited way during the pressure test of the oil and gas well and maintain the minimum flow rate under high pressure, effectively reducing the failure rate of the system. In the normal test mode, the power train components are often damaged by the impact load, which is one of the major sources of faults that are common in the market. Cummins electronic control test mode, using innovative design, effectively prevent the occurrence of such failures.
The QTR series transmissions are exceptionally reliable, reliable and durable, and are optimally matched to the Cummins QSK50 and QSK60 engines. At the same time, the gearbox series can also directly replace the traditional gearbox in use, which is easy to operate. This flexibility gives equipment operators the opportunity to experience world-class Cummins products and their superior quality without requiring a complex redesign of the system.
