On November 3, 2009, the first engine of Shanghai Pu'an Diesel Engine Co., Ltd. (hereinafter referred to as "Shanghai Pu'an") was put on the line in Shanghai Baoshan City Industrial Park. Leaders of Shanghai Pu'an and South Korea’s Doosan Corporation, and the district’s director of Baoshan District, the National Development and Reform Commission, and Baoshan City Industrial Park participated in the off-line ceremony. As a star in the domestic heavy-duty diesel engine industry, what is the life experience of Shanghai Pu'an? What are the main products? What is the current production capacity? To this end, our reporter specially interviewed Chen Jian, deputy general manager of Shanghai Pu'an, to learn about Shanghai Pu'an.
Automotive diesel network: Hello Chen, as a new diesel engine company, surely everyone is not too familiar with Shanghai Pu'an, please also tell us about the company's situation in Shanghai Pu'an, right?
Chen Jian: Shanghai Pu'an Diesel Engine Co., Ltd. was formally established in July this year. It is a modern engine manufacturing company invested in the high-power diesel engine technology of Doosan Infracore Co., Ltd. in Shanghai. Established in 1896, Korea Doosan Group is one of the oldest companies in Korea and is one of the world's leading integrated enterprise groups. In April 2005, Doosan Group successfully acquired the original Korean Daewoo company and changed its name to Doosan Infracore Co., Ltd., which mainly produces engines, excavators, forklifts, and armored vehicles. In 2007, it began to negotiate cooperation with Shanghai Pu'an and hopes to enter the heavy truck market in China. The new plant of Pu'an Diesel Engine Company in Baoshan district of Shanghai is planned to occupy an area of ​​87,000 square meters. In the first phase, it plans to produce 30,000 high-power diesel engines annually. The total investment is about 500 million yuan, and it will be put into use at the end of 2010.
Automotive diesel network: What is the basis for the cooperation between Shanghai Pu'an and Doosan? What are the advantages of cooperation with Doosan?
President Chen: Shanghai Pu'an and Doosan's cooperation is based on the mutual benefit of both parties. Doosan, Korea has a high reputation in the international and domestic markets for construction machinery and generator sets. It also hopes to make a difference in the domestic heavy-duty diesel engine market.
Automotive Diesel Engine Net: What are the series of products of Shanghai Pu'an Company and what products are mainly used in?
Mr. Chen: Shanghai Pu'an Technology's introduction of Doosan's products in South Korea mainly includes DV11 series, DL11 series, and DV15 series. They are V-type 6-cylinder, in-line 6-cylinder, V-type 8-cylinder, displacement 11~15L, and power 330~460Ps. . At the same time, Shanghai Putian machine imported Doosan DL06 series and DL08 series diesel engines are all in-line 6-cylinder, displacement 6-8L, and power 230-340Ps.
Shanghai Pu'an's entire product range covers 230~460Ps. The product has a wide range of applications. It is mainly used in all types of heavy trucks, luxury passenger cars and construction vehicles.
Vehicle diesel network: At present, the domestic heavy-duty diesel engine market is very fierce, and there are many models that use foreign technology. Does Chen think that Shanghai Pu'an's products have competitive advantages over other domestic companies?
Mr. Chen: First of all, Shanghai Pu'an's diesel engine products from Doosan, Korea, are advanced in technology and suitable for the Chinese market, because Korean Doosan technology originates from the introduction of the world's leading heavy-duty diesel engine technology from Doosan, Germany. High-pressure common-rail and SCR post-processing systems are in line with China. Market emission strategy. Second, Shanghai Pu'an, as a private enterprise, has a very good operating mechanism and can respond flexibly and quickly to changes in the market. In addition, South Korea’s Doosan’s technical support for Shanghai’s security and Korean Doosan’s perfect after-sales service system in the Chinese market will also provide service protection for Shanghai Pu’an.
Automotive Diesel Engine Net: What is the current product mix of Shanghai Pu'an? How about the expected production capacity?
Mr. Chen: In 2009, Shanghai Pu'an focused on the infrastructure and supporting tests of the factory. At present, the first-phase production line has been completed and put into use. Starting from CKD, it has formed an annual production capacity of 5,000 heavy-duty diesel engines.
Diesel Engine Net: How do you think about the diesel engine market next year? What is the forecast for the production and sales of Shanghai Pu'an next year?
Mr. Chen: At present, there is no obvious improvement in the domestic diesel engine market. The infrastructure construction such as the high-speed railway will bring new opportunities to the heavy truck market in China. It is expected that the heavy truck market in China will develop more rapidly in the next few years and at the same time, The demand for quality engines will also increase, and there are relatively few 11L high-quality diesel engine products in the Chinese market. It is believed that Shanghai Pu'an will develop rapidly.
Diesel Engine Net: Thanks to Mr. Chen for accepting our interview. Shanghai Pu'an is a rising star in the heavy machinery industry, but the cooperation with Doosan of South Korea makes Shanghai Pu'an have mature products and technologies, and they also get after-sales service. Protection. As a result, Shanghai Pu'an's starting point is higher than other domestic companies, let us wait and see, pay attention to this dazzling "nova."
Reverse Circulation Water Well Drilling Rig
Reverse circulation (or RC as it`s more commonly known) drilling is an essential tool in the mining industry. In addition to other oil rigs and drill rigs, reverse circulation drills assist in the productivity and accuracy in mining jobs.
RC drilling is a drilling method involving a large rotary drill and Air Compressor that yields high quality mineral and rock samples, free from contamination and material interference.
It is the preferred method of mineral exploration, drilling and in-pit grade control because it is fast and cost-effective.
What is RC Drilling?
Much like air core drilling, RC drilling returns cutting to the surface through an inner tube inside the rod. This is achieved by blowing air down the rods at a rate up to 1500 Pascals. This creates a pressure differential that pushes cuttings and water up via air lift.
The drilling component is powered by a pneumatic reciprocating piston (also known as the hammer), which drives a steel drill bit.
The two most commonly used drilling bits in RC systems are the fixed cutter and roller cone, both of which are advantageous depending on the project and geographical location of the site.
RC drilling is primarily used on large machinery and drill rigs and often goes to depths of 500 metres.
High quality RC equipment also has the ability to dry out the rock with large air compressors before the drill hits, which provides dry rock chips and, in turn, better samples.
Reverse circulation drilling is the predominant technique based on a number of advantages.
.A higher percentage of uncontaminated cuttings
.Drilling rate similar to open hole drilling, but can often be faster and penetrate greater depths
.One of the most accurate drilling methods
.Quick retrieval of sample rates
.Dry samples allow for easier analysis
