Pipeline pump work serious gas resistance solution
Pipeline pumps are the most common equipment currently used in oil delivery systems. However, its biggest problem is low suction, easy to produce air resistance; the same time, if the actual flow in the pipeline and the rated flow more difference between the formation of oil and gas mixed transport, will lead to double the oil transmission time, waste of electricity doubled.
Oil tank zero tank is buried in the horizontal tank, pipeline pump installed in the ground pipe. Working pump sucked the oil from the underground horizontal tank into the pump, the vertical height is the pump suction. Gasoline 20 ° C suction over 4.27 meters began to vaporize, suction more than 4.5 meters can not work properly.
Negative pressure suction conveying oil, the pipeline in negative pressure working state, when the pipeline at a point the remaining pressure is less than the saturated vapor pressure of oil operating temperature, the oil will be a large number of vaporization, resulting in discontinuous flow or flow Phenomenon, this is gas resistance. Once the air resistance, the entire oil system can not work properly, this also need to support the installation of vacuum systems.
The green card submersible pump is immersed in the tank at the bottom of the tank directly through the impeller to the oil pressure, the oil will be pushed to the target storage tank, to achieve the oil or zero tank canning oil. Because it is a positive pressure transmission oil, high flow submersible pump does not produce air resistance, there is no suction problem.
The core technology to solve this problem ------ submerged motor or shielded motor, there is a gap between the stator and rotor of the motor about the thickness of an A4 paper, the oil flows through the middle, play Two functions: First, the motor cooling, almost all of the motor can only flow through the motor to achieve the cooling effect, thus protecting the motor life. Submersible pump motor fluid inside the characteristics of this motor doubled the life. Second, the liquid flow through the gap between the stator and the rotor, the bearing play a good role in lubrication. Motor and bearing problems have been effectively resolved, so that submersible pump does not require maintenance, low failure rate. Service life of up to ten years, shelf life of three years.
Green card submersible pump shielded motor is the latest design, lower temperature rise, longer life, completely independent intellectual property rights, manufacturers Jiama Machinery Plant in Tianjin is the only professional research and development, design, production submersible pump shielded motor units.
In addition, GMA Machinery Co., Ltd. has been continuously developing new products and has launched several series and dozens of submersible pump varieties. A variety of submersible pump models meet different demands for different flow heads, enabling submersible pumps to work in an efficient range with more reasonable selection, The use of more energy-saving, but also according to the actual needs of users of special design, providing tailor-made services. Standard submersible pumps, submersible pumps, high-lift submersible pumps, variable frequency submersible pumps also introduced for the railway trestle unloading oil crane submersible pump. In terms of lift and flow, Green card submersible pump to fill the gaps in the world's submersible pumps, launched a series of high lift submersible pumps, head up to 100 meters, large flow series submersible pumps, flow up to 80m3 / h or more. The submersible pumps require the lowest tank level of not less than 400mm, an increase of the effective oil storage tank volume. It is suitable medium for gasoline, diesel, kerosene and submersible pumps specially designed for special media such as 100% methanol, 100% ethanol, over 15% methanol, isopropanol, ethyl acetate and toluene. Green card submersible pump warranty period of three years, this is the same industry submersible pump can not be compared to the advantages.

Eco-friendly Packaging Color Box
What products are the environmentally friendly packaging color boxes suitable for:
The environmentally friendly packaging color box is mainly suitable for some small-sized products.Because its commercial cost is too high, there is not a large amount of popularization.After the technology matures in the future, the environmentally friendly packaging color box will definitely become one of the mainstream.
Environmentally friendly packaging materials generally include reusable and renewable packaging materials, edible packaging materials, degradable materials and natural paper materials. Environmentally friendly packaging is reflected in the use of materials, the least waste and energy saving, and easy recycling and reuse. Packaging waste does not produce secondary pollution.
