Submersible pump is a pump installed in the tank for the tank connected to the tanker common use. When refueling can not hear the sound, the pipeline from the trunk of the tank exports to support the tanker products. Submersible pump core components are shielded motor. Raiders: How can we buy a well-intentioned pump? Submersible pumps according to their main purpose can be roughly divided into four kinds, submersible pumps for gas stations, submersible pumps for oil depots (tanker), submersible pumps for unloading oil tanks for tank trucks, and submersible oil pumps for oil wells. Below, please follow the Asian Fluid Network Xiaobian, we work together to understand the 360 ​​° submersible pump this product. Gas station submersible pump submersible pump selection, first of all according to the use of the power supply voltage of the submersible pump rated voltage. In conditions permitting, try to choose the rated voltage of 380 volts three-phase submersible pump, because the same power 380-volt three-phase submersible pump motor 220-volt single-phase submersible pump motor loss, high efficiency, caused Fever is low. 220 volts of submersible pump must be equipped with capacitors, and the capacitor life is much lower than the submersible pump, which inevitably replaced. In addition, the selection should be based on tank size tank diameter, pipe diameter, pipe length and head, flow and other conditions, the most suitable and most efficient selection of submersible pump. Generally according to the manufacturer's sample to provide a variety of submersible pump performance curve selection, or commissioned by the manufacturer for calculation and selection. Tank depot (tanker) Submersible pump for underground tank oil, oil transfer. Submersible pump tanker (tanker) than the gas station submersible pump flow is much larger, usually 300 ~ 1000 liters / min, so the corresponding submersible pump power should be much larger. Underground tanks to pay oil stations generally 50-60 legislation / hour, pressure but also about 2 kg, the general election of more than 5. There is also a "self-adaptive submersible pump", although the power is small (1) flow, but must be used in conjunction with the pipeline pump. Particularly suitable for the original underground tank oil pump has been installed self-priming pump, but due to large air resistance needs to be rebuilt. Tank car crane tube unloading with submersible pump tank truck unloading process due to air resistance problems become extremely complex. The earliest is the air suction tank filling pump, because the safety factor has been disabled. According to the textbooks of China University of Petroleum, there are the following types of tanker unloading oil: Night unloading method (the use of night low temperature environment), water cooling method, tank car sealed inflatable (inert gas) method, down layered unloading method. Submersible pump manufacturing process can be divided into liquid and electric. Submersible oil pump Submersible oil pump is a multi-stage centrifugal pump, mainly by the multi-stage impeller, guide shell, pump shaft, pump casing and the upper and lower joints and other components. Multi-section pump can be connected through the coupling flange and spline sets in series to meet the needs of head. Submersible pump to adapt to different types of well conditions. The impeller and guide shell with nickel cast iron and the K-500 Monel alloy pump shaft provide a satisfactory operating life of the pump at maximum strength and load. In order to adapt to well conditions, component bearing and simplified assembly, multi-stage submersible pump in the form of assembly using full floating, full compression or semi-floating three, the structure is divided into radial flow and mixed flow In use, divided into standard pump, sand control pump, anti-corrosion pump. In addition, the main difference between self-priming pump and submersible pump gas station is self-priming pump tanker complex, relatively submersible pump fault more, due to the negative pressure within the pipeline, easy to generate gas and gas resistance, etc., submersible pump refueling The internal structure of the machine is simple, the failure rate is very low, and the submersible pump on the storage tank will not be more than 10 years. Pipeline is also relatively simple, but due to the pipe in a positive pressure on the pipeline seal higher, if the pipe rupture will emit a lot of oil. Of course, the submersible pump system also has corresponding preventive measures. In addition the submersible pump power distribution a little more complicated.
