1. Gas station with submersible pump without self-priming pump What are the advantages? (1) submersible pump a pump with multiple guns, eliminating half of the pipeline. Self-priming pump refers to the pump installed in the tanker, refueling motor and pump rotation when the sound, and each tanker pump must have a separate pipeline leading to the tank. Selection of submersible pumps, each tank only need to put a pump, a total pipeline, several fuel gun divided into several trails. Select a submersible pump with multiple guns, which is to use a submersible pump instead of using a few self-priming pump. (2) The selection of submersible pumps is in the long-term interest. Submersible pumps once invested more money than self-priming pumps, but the service life of up to ten years, the life of self-priming pumps, but three to five years, and the use of self-priming pumps require maintenance, self-priming pump tanker complex structure, the relative submersible pump failure More from time to time it is necessary to maintain, repair, choose the submersible pump will never need to do these jobs, installed after eight years do not move. (3) submersible pump to meet the gas station large flow refueling needs. Self-priming pump flow far less than the submersible pump. (4) The submerged pump fundamentally eliminates the phenomenon of air resistance, and utilizes the principle of positive pressure push to fundamentally solve the negative pressure principle of pipeline pump, positive displacement pump and vane pump under high temperature environment, high lift and long distance conditions Pump can not solve the problem (such as less oil, not even the drawbacks of oil). (5) Submersible pump is environmentally friendly energy-saving new products. At present, Green brand new product frequency conversion submersible pumps can save up to 50% energy. Self-priming pump power consumption is much larger than the ordinary submersible pump. (6) Green card submersible pump explosion-proof rating is Exsd â…¡ AT3, zero zone explosion-proof, more secure than the self-priming pump. National standards clearly proposed gas station recommended submersible pump 2 submersible pump at home and abroad is how the situation? The United States at the end of the last gas station has been the actual submersible pump popularity. China is now PetroChina, Sinopec's new gas station, gas stations all converted with submersible pumps. More and more social gas stations also recognize the advantages of submersible pumps, submersible pumps are at a stage of rapid popularity, gas station submersible pumps instead of self-priming pumps become inevitable. 3. Under what circumstances submersible pump self-priming pump particularly obvious advantages? (1) Refuel the tanker. When you need a big flow. (2) Diesel gun 2 inches and above diameter, and a pump with more than two gun when. (3) Want to use a pump with more guns. (4) When the distance between the tanker and the tanker is far, gas-resistance often occurs in the self-priming pump and the pump can not pump out the gas 4. What are the manufacturers of the submersible pump at home and abroad? The fifties of last century, gas station submersible pump is developed from the United States Franklin explosion-proof shielded motor developed, the core technology is shielded motor. Franklin's gas station submersible pump commonly known as Lan licensing, or blue jacket. US red jacket gas station submersible pump is a world-renowned brand, but it uses shielded motor is also manufactured by Franklin. China now also has a submersible pump manufacturers green card gas station submersible pump products from 0.75HP low power to high-lift, high-flow, variable frequency submersible pump to meet almost all the needs of users, including gas stations, oil depots, ships, internal combustion engines Train, factory production line. This project has won a number of national patents, and accept and complete a number of government research projects in Tianjin task. 5. Red jacket submersible pump and the domestic green card submersible pump comparison (1) brand history: red jacket for the submersible pump well-known brand, 60 years of production history; green card submersible pump was born just six years. (2) core technology: Red Jacket submersible pump core components - shielded motor purchased from Franklin; Green card submersible pump shielded motor with the latest design, lower temperature rise, longer life, completely independent intellectual property rights, the manufacturer Tianjin Jiama Machinery Factory is the only professional research and development, design, production submersible pump shielded motor units. (3) product line: There are few new products introduced red jacket, the general standard sample specifications only, 3HP, 5HP submersible pump only one of the specifications; Green card submersible pump continued research and development of new products, has introduced a number of series, dozens of potential Pump varieties, a variety of models of submersible pumps to meet the needs of different flow head, the submersible pumps in the efficient range of work, the selection is more reasonable, the use of more energy-efficient, but also according to the actual needs of users of special design, tailor-made services. (4) minimum level requirements: red jacket provides the lowest level in the tank not less than 800mm; green card submersible pump requires the lowest tank level of not less than 400mm, an increase of the effective oil storage tank volume. (5) Medium: Red Jacket submersible pumps for gasoline, diesel, kerosene, etc .; Green card submersible pumps in addition to gasoline, diesel, kerosene, specially designed submersible pumps used in special media, such as 100% methanol, 100% ethanol , More than 15% methanol gasoline, isopropanol, ethyl acetate, toluene and so on. (6) Head and flow: Green card submersible pump to fill the gap of the red jacket, the introduction of high lift submersible pump series, up to 100 meters head, large flow series submersible pump, the maximum flow of up to 80m3 / h or more. (7) some special applications: red jacket is blank; Green card submersible pump is also applicable to the railway trestle unloading oil crane submersible pump. (8) Warranty: Red jacket submersible pump for one year; green card submersible pump for three years. (9) Price: red jackets submersible pumps higher prices; green card submersible pump price lower than red card 10% -20%. 6. Green card submersible pump use cases mainly cited several? â—Ž At the end of November 2008, Tianfu Group defeated a big foreign manufacturer in the bidding for the railway project of China Railway 20th Bureau of Angola, winning 204 submersible pump projects at a reasonable price and long warranty period. The first 32 submersibles Oil pump has been assembled, to be checked after the packing and transportation of Party A, to Shanghai to Hong Kong. â—Ž On July 8, 2009, Zheng (State) Chang (State) Project, the first finished light oil pipeline in China designed by PetroChina Pipeline Bureau, has decided to adopt green card submersible pumps, Lanzhou and Zhengzhou projects across the board Section has now begun to install. â—Ž At 16:00 on June 8, 2009, Director of Development and Planning Division of Sinopec Headquarters and Director Song Wei verbally indicated: The green card submersible pump can be supplied to the finalist tanker plant. At this point, the sign green card submersible pump after rigorous testing of scientific research, up to three years of operation, with no fault results finally won the approval of the domestic authorities. The major users can be sold to the headquarters of Sinopec Development Company of Song Wei, director of consulting and verification.
