The LCB asphalt pump is primarily used for transferring 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 leakage and return channels, which result in minimal torque forces on the gears during operation, thus reducing bearing load and wear. It is equipped with a valve for overload protection, with the full回流 pressure at 1.5 times the pump's rated discharge pressure. This valve can also be adjusted within the allowable discharge pressure range as needed. However, note that this valve is not suitable for long-term operation as a pressure-reducing valve and should be installed separately on the pipeline if required.
Structural Features:
The LCB type asphalt pump is mainly composed of gears, shafts, pump bodies, pump covers, bearing sleeves, shaft end seals, etc. The gears are manufactured using a double-circular arc sine wave tooth shape. Compared to involute gears, its advantage is that there is no relative sliding between the tooth profiles during the gear meshing process, thus there is no wear on the gear surface, operation is smooth, no liquid leakage, low noise, long lifespan, and durability.
The LCB asphalt pump is primarily used for transferring various lubricating liquids with temperatures not exceeding 70°C. For temperatures up to 200°C, please contact our company for suitable materials. The viscosity range is 5×10-5 to 1.5×10-3 m2/s. This pump is mainly suitable for transporting various oils, such as heavy oil, diesel, and lubricating oil. With copper gears, it can transfer low pour point 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 tooth and is carried to the discharge side. When the gears engage again, the liquid is expelled out of the pump.
Selecting Pump Considerations:
The correct selection is crucial for achieving the desired operational effectiveness. To cater to the varying physical, chemical properties, and operational requirements of different mediums, we suggest the following process: The user provides pump operating data, our factory personnel recommend the selection, and the user confirms. When selecting a pump, attention should be given 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 Usage Scenarios.
5. Installation environment requirements: horizontal or vertical, fixed or mobile, and pipeline connections.
