Integrated innovative centrifugal pump energy-saving significance
Zhang Shengchang believes that the integrated innovative centrifugal pump has high-efficiency and large-flow injection pump equipment with large flow, high discharge pressure, wide performance, high efficiency, long life, and high reliability. This product replaces traditional centrifugal pump water injection equipment with low operating efficiency. It is of great practical significance to reduce oil production costs in oil fields.
After adopting the innovative stable balanced volute, the impeller of the centrifugal pump is balanced by radial forces and the force of the bearing is extremely small, which can effectively improve the mechanical efficiency of the centrifugal pump, improve the working efficiency of the centrifugal pump, and ultimately achieve the purpose of energy conservation; After the type of mouth ring, the volumetric efficiency, cavitation performance and hydraulic efficiency of the centrifugal pump are effectively improved, the working efficiency of the centrifugal pump can be effectively improved, thereby achieving the purpose of energy saving; the innovative balancing hole assist mechanism can change the balance hole back through the structural innovation. The flow direction of the medium is the same as the flow direction of the media inside the impeller, which eliminates the influence of the traditional balanced hole return media on the flow state of the media inside the impeller, thereby improving the cavitation performance and hydraulic efficiency of the centrifugal pump.
Analyze from the market application prospect, the centrifugal pump is a kind of general-purpose mechanical product with large consumption and wide application. The market demand of the product accounts for about 80% of the total demand of the pump products. Therefore, it is of great significance to carry out energy conservation and consumption reduction for large-scale centrifugal pumps.
Large-flow and high-efficiency reciprocating oilfield water injection pump has a good market prospect. Large-flow and high-efficiency reciprocating oilfield water injection pump is a high-efficiency and large-flow reciprocating injection device with high flow rate, high discharge pressure, good performance, high efficiency, long service life, and high reliability. Pump equipment. This product replaces the current centrifugal pump with low operating efficiency and part of the low-efficiency, low-flow reciprocating pump to improve the entire water injection pipe network operating efficiency and motor utilization, save a lot of energy and operation and maintenance costs, to achieve energy conservation, It is of great significance to increase energy efficiency.
Zhang Shengchang pointed out that the total capacity of the drive motors for injection pumps in existing oilfields ranged from several hundred kilowatts to several thousand kilowatts, with a total capacity of over 10 million kilowatts, accounting for more than 60% of the total oil field oil consumption. Therefore, the efficiency of the water injection pump unit is not only directly related to the level of energy consumption, energy saving and consumption reduction, but also relates to the cost of oil production.
The pressurized water injection in oil fields has become one of the advanced oil production processes in China's oil fields, and is also an important measure to ensure stable production and high yields in the oil fields. According to statistics, there are more than 30 large and small oilfields in China, and more than 300,000 oilfields. A large number of high-pressure injection pump stations are required to carry out oilfield water injection operations. It is conservatively estimated that there are more than 20,000 injection pumps in China's oil fields. A considerable amount of centrifugal pump equipment is replaced, and a large number of equipment that has expired life each year also needs to be replaced, and the market prospects are promising.
Large potential demand for diaphragm pumps
From the technical characteristics of the diaphragm pump, this product is a volumetric non-leakage reciprocating pump that uses a flexible element (diaphragm) to flexibly deform and convey the medium. The pump driving medium and the transmission medium are separated by a diaphragm and is a volumetric reciprocating pump. The hydraulic end has a low flow velocity and is resistant to wear, so that it has outstanding advantages in solid-liquid mixing. The product discharge pressure up to 20MPa, can achieve long-distance transmission of high-concentration media, reduce the internal diameter of the pipeline, reduce the number of pumping stations, significantly reducing the investment in the project. Compared with other pump products, it can save more than half of the operating costs.
Zhang Shengchang pointed out that because the product is widely used in coal gasification and liquefaction projects, it plays an important role in national energy security, energy structure adjustment, improvement of coal utilization rate, increase of crude oil production, and reduction of pollution. The market has broad application prospects.
Taking coal chemical industry as an example, in the annual output of 2.5 million tons of coal liquefaction project in Shenhua, there are only 20 sets of diaphragm coal slurry pumps, and the introduction cost will be as high as 800 million yuan. It is estimated that by 2030, China's coal liquefaction will reach a scale of 30 million tons per year. If the pump is all dependent on imports, it will require about RMB 10 billion.
In pipeline coal transportation projects and power plant mortar transportation projects, diaphragm pumps are their key transportation equipment, accounting for one-third of the total project investment, and the potential demand is huge.
In addition, dozens of diaphragm pumps imported from foreign exchange companies in Lunan, Dingnan, Dezhou, Huainan, Shanghai, Juhua and other chemical companies are required to be replaced after their useful life expires. Taiyuan Steel Plant in Shanxi Province imported two pumps from the Netherlands in 1993 and 1998 and spent more than RMB 60 million. It is reported that a unit in Yunnan also has to build five transmission slurry pumping stations, the introduction of GEHO diaphragm pumps more than ten units. In addition, China's steel plant environmental protection projects have also introduced several ABEL diaphragm pumps.
Significant economic benefits for oil and gas mixed pump
The oil-gas mixture pump can save a large number of oilfields from investing in the construction of decentralized oil and gas separation devices, reduce the investment in offshore oil drilling platforms, increase the amount of crude oil extracted and reduce environmental pollution, and has significant social and economic benefits. At present, the widely used oil-gas mixed-phase pumps mainly include screw pumps and external circulation piston pumps.
When the screw pump is working, the liquid is sucked into the sealed space enclosed by the thread and the pump shell. When the active screw rotates, the screw pump sealing volume increases the pressure of the screw pump under the compression of the screw teeth, and moves along the axial direction. Due to the screw type constant speed rotation, the liquid outflow flow is also uniform.
In the outer circulation piston pump, the synchronous gear drives the two rotors to rotate in the reverse direction. In this process, when the rotor is at the inlet side, the suction chamber volume increases to form a vacuum and the conveying medium is sucked into the pump chamber. When the rotor continues to rotate and the medium is delivered to the discharge side, the volume of the discharge chamber is continuously reduced, the medium pressure is increased, and it is pressed out of the pump chamber. The two rotors constantly rotate so that the medium is continuously sucked in and discharged.
According to the latest survey statistics, the annual demand of the four oilfields of Shengli, Zhongyuan, Changqing and Tuha has reached more than 300 sets, and the average number of domestically produced turbines per unit has been analyzed. From 250,000 to 300,000 yuan, the annual output value is nearly 100 million yuan, and the annual profit is expected to be more than 30 million. In 2008, the output value of oil and gas mixed-use pumps of two companies, namely Tianjin Pump Machinery Group Co., Ltd. and Tianjin Reid Screw Pump Manufacturing Technology Co., Ltd., reached 50 million yuan.

The pump for wind power generation uses hydraulic pumps to convert wind energy into hydraulic energy, so that the efficiency of wind energy utilization is high, and it is easy to store; and it can realize power generation at the wrong time in different places; it greatly improves the efficiency of wind power generation; and it can reduce the influence of wind fluctuation on the power generation voltage. Therefore, the hydraulic pump for wind power generation is of great significance to the development of the global wind power business.
From the prospect of wind power development, the world wind power growth rate has been maintained at more than 30% in recent years. With the localization of wind power installed capacity in China and the scale of power generation, the cost of wind power is expected to drop again. Therefore, the wind power market has also become a place for more and more investors.
According to national plans, in the next 15 years, the installed capacity of wind power in the country will reach 20 million to 30 million kilowatts. Calculated at an investment of 7,000 yuan per kilowatt of installed capacity, the future market for wind power equipment will reach 140 billion to 210 billion yuan. This huge market demand provides a good space for the development of pumps for wind power generation.
Oil Dosing Pump Increases Oil Production
The main crude oil production field has entered the "three high" stage. That is, crude oil has high wax content, high corrosiveness, and high viscosity, which brings great difficulty to the mining work. This requires the addition of some liquid chemicals to the oil fields during the mining process, which can extend the life of oil wells and also increase crude oil production to some extent.
According to the preliminary statistical analysis of various oil fields, the total number of oil wells in Daqing, Shengli, Karamay, and Changqing oilfields in China totals more than 300,000. In the future, it is expected that each oilfield in the country will need tens of thousands of sets of products each year, with a large market. prospect.
