The LCB asphalt pump is primarily used for conveying lubricating oils or other liquids with similar properties that do not contain solid particles or fibers, are non-corrosive, and have a temperature not exceeding 80°C with a viscosity ranging from 5×10^-6 to 1.5×10^-3 m²/s (5-1500 cSt). The pump features oil outlet and return channels, which result in a smaller torque force on the gears during operation, thereby reducing bearing load and wear. The pump is equipped with a valve for overload protection; the full回流 pressure of the valve is 1.5 times the pump's rated discharge pressure and can also be adjusted within the allowable discharge pressure range as needed. However, note that this valve is not intended for long-term use as a pressure-reducing valve; an additional installation on the pipeline is required if necessary.
Structural Features:
The LCB asphalt pump primarily consists of gears, shafts, pump bodies, pump covers, bearing sleeves, shaft end seals, etc. The gears are manufactured using a double-arc sine curve tooth shape. Compared to involute gears, the advantage is that there is no relative sliding of the tooth profiles during the gear meshing process, hence there is no wear on the gear surfaces, ensuring smooth operation, no liquid ejection, low noise, long service life, and durability.
The LCB asphalt pump is primarily designed for conveying various lubricating liquids with temperatures not exceeding 70°C. For high temperatures up to 200°C, please contact our company for suitable materials. The viscosity range is 5×10^-5 to 1.5×10^-3 m^2/s. This pump is mainly used for transporting various oils, such as heavy oil, diesel, and lubricating oils. With copper gears, it can convey low flashpoint liquids like gasoline and benzene.
The LCB asphalt pump features a pair of rotating gears within the pump body, dividing the entire working chamber into two separate sections through the interlocking of the gears. As the pump operates, the driving gear rotates the driven gear. When the gears disengage, a partial vacuum is formed on the suction side, drawing in the liquid. The liquid fills the grooves of each gear and is transported to the discharge side. When the gears engage, the liquid is forced out and expelled from the pump.
Selecting Pump Considerations:
Proper selection is crucial for achieving the desired operational effect. To cater to the different physical and chemical properties of the medium and operational requirements, we recommend the following process: The user provides the pump operating data, our factory staff will make the selection and recommendation, and the user will confirm. When selecting a pump, pay attention to the following points:
1. Lubricity, cleanliness, and corrosiveness of the medium.
2. Viscosity and temperature of the medium.
3. Inlet and outlet pressure of the medium, installation height.
4. Requirements for Application Scenarios.
5. Installation environment requirements: horizontal or vertical, fixed or mobile, and pipeline connection specifications.
