Tongjiang electric submersible pump frequency conversion transformer manufacturer [Tianjin Aote pump industry]

the pump type is appropriate, and the electric submersible pump with detailed parameters is very good. If you want to buy something, hurry up. There is a very useful electric submersible pump in Tianjin Aote pump industry, waiting for you to choose the right pump type Oh electric submersible pump system

the electric submersible pump system consists of three parts: ground equipment, power transmission and downhole units. Ground equipment includes transformer, control cabinet (frequency conversion cabinet), junction box, etc. Power transmission is composed of power cables, connecting cables, etc. The downhole unit is composed of submersible motor, protector, separator (or port) and multistage centrifugal pump. As required, centralizers, single flow valves, relief valves, sensors and other devices are generally installed underground

in order to adapt to oil wells with different production casings, the electric submersible pump system is designed into different specification series, which can be applied to production casings above 5 ", 51/2", 7 ", 85/8", 9 5/8 ", etc. Displacement: 30-2800m3/d (BPD) lift: <3800m (12460ft) gas separator can be configured with port and gas separator according to the gas containing conditions of the oil well. The gas separator is divided into sedimentation separator and rotary separator in structural principle, and is divided into standard separator, wear-resistant separator, corrosion-resistant separator and high-efficiency separator in use. Protector SLP protectors include sedimentation protectors, sedimentation protectors and sedimentation hybrid protectors. Different types of protectors can be configured according to the service conditions and user requirements. Submersible motor submersible motor is a three-phase squirrel cage asynchronous motor. Its shape and structure are fine 87 polymer lotion building waterproof coating and long. SLP motors are suitable for bushings of 5 ", 51/2", 7 ", 95/8" and above. The working voltage of the submersible motor is 140v-3600v and the working current is 14-104a. The strength and plasticity indexes of the metal during tension are measured by the microcomputer hydraulic servo universal testing machine. The high-power motor can be connected in series with multiple sections. The rated speed at 50Hz is 2850r/min (the rated speed at 60Hz is 3420r/min). Its temperature resistance grades are: 50 ℃, 90 ℃, 120 ℃, 150 ℃, 180 ℃

this entry is reviewed by the "popular science China" science encyclopedia entry compilation and application work project. Electric submersible pump is a multi-stage centrifugal pump working underground. It goes down into the well together with the oil pipe. The ground power supply transmits electric energy to the underground submersible motor through the transformer, control panel and power cable, so that the submersible motor drives the multi-stage centrifugal pump to rotate, converts electric energy into mechanical energy, and lifts the well fluid in the oil well to 9. Maximum impact height: 2000mm ground. As an important mechanical oil extraction equipment, electric submersible pump has a history of nearly 20 years since the introduction of electric submersible pump technology in 1981. Since the introduction of electric submersible pump technology in 1981, China has a history of more than 30 years. As an important mechanical oil production equipment, electric submersible pump has been widely used in oil fields. Up to now, electric submersible pump has developed into a complete system instead of a single equipment. It is composed of downhole temperature and pressure measurement and control device, submersible motor, protector, separator/port, submersible centrifugal pump, combination of single flow valve and oil drain valve, submersible cable, control cabinet/frequency converter, junction box, transformer, etc

at present, there are two main types of water injection equipment used in oil fields, namely, surface centrifugal pump and plunger pump. Large displacement of surface centrifugal pump, low water injection cost and the need for fixed plant and water injection pipe are the main ways of large-scale water injection development; The plunger pump has high pressure and high pump efficiency, which is suitable for the establishment of small water injection stations. To adapt to small high-pressure water injection blocks, pump rooms, pipes, etc. need to be established, and sometimes water source wells need to be drilled. The high-pressure injection increase technology of electric submersible pump is based on mature electric submersible pump products to solve the water injection of low-permeability oil reservoirs and remote well areas in the oilfield restricted by the existing pipe design, pipe distance, and the safety stroke force rise of the emergency stop key of water injection pressure. 1. Process principle 1 - incoming water pipeline; 2-high pressure check valve; 3-high voltage over cable wellhead; 4-frequency conversion control cabinet; 5-tubing hanger; 6-power cable; 7-inverted centrifugal pump; 8-connecting cable; 9-water injection nozzle; 10 protector; 11 - submersible motor; 12 water injection layer uses water from the ground

at present, domestic electric submersible pump production system manufacturers belong to the subordinate enterprises of PetroChina, Sinopec and CNOOC. The electric submersible pump products produced by them are mainly supplied to the oil fields and oil and gas development projects subordinate to PetroChina, Sinopec and CNOOC, and the remaining products are exported and sold domestically. Other joint venture or private manufacturing enterprises mostly export electric submersible pump products, and the export volume accounts for more than 60% of the total output of electric submersible pumps. In 2011, the output of electric submersible pump production system equipment in China was about 9700 sets. In 2012, the output of electric submersible pump production system equipment in China was about 10200 sets, with a year-on-year increase of 5.15. For 13 years, the output of electric submersible pump production system equipment in China was about 11000 sets, with a year-on-year increase of 7.84%. At present, the domestic electric submersible pump production system industry has not yet formed a trend of clustering. In terms of the number of enterprises, there are a large number of electric submersible pump manufacturing enterprises in Tianjin, about 4-5 in terms of enterprise scale and production capacity
