Gear pumps are used to transport viscous liquids such as lube oil and combustion oil. They should not be used to transport liquids with lower viscosity (such as water and gasoline), liquids containing particulate impurities (affect the service life of the pump) Lubrication system pumps and hydraulic system pumps, widely used in engines, steam turbines, centrifugal compressors, machine tools and other equipment. Gear pump high process requirements, not easy to get accurate match. Below to introduce several unique gear pump products.
NBX series of spur-toothed internal gear pump is a new design with the international advanced level of hydraulic power components, it has a simple structure, low noise, long life, low pollution sensitivity and so on. Widely used in mining machinery, engineering machinery, plastic machinery, metallurgical machinery, auxiliary power stations, petrochemical machinery, food packaging machinery, precision machine tools, general-purpose machine tools and other mechanical hydraulic system.
Technical innovation features:
1, a special tooth profile: NBX pump external gear profile is a straight line, ring gear is a linear conjugate line
2, two-stage pressure: NBX pump using two-stage pressurized structure, does not increase the spindle load, increase pump output pressure, extend pump life.
3, hydrostatic bearing: NBX pump no axial load, the axial gap between the ring gear and the pump housing is small, during which full of oil, forming a dynamic and static pressure bearings.
4, modular design: NBX pump main parts of a high degree of standardization, suitable for advanced modular design.
5, the use of straight-tooth conjugate meshing principle, the gear tooth shape using straight lines, and the establishment of the best tooth angle, ring gear tooth line with linear conjugate line, so that after the engagement without sleepy oil zone, so as to achieve stable, accurate , High, volume efficiency, low noise, the ideal effect.
Gear pump KCB-7600 Hengsheng
This series of gear pump gear, shaft, pump, safety valve, shaft seal composed of the end. The gears are heat-treated to a higher hardness and strength and mounted with the shaft in a replaceable hub. The lubrication of all parts in the pump is automatically achieved using the output medium while the pump is in operation.
The pump has a well-designed drain and return tank, the gear torque in the work to bear the smallest, so the bearing load, wear a small, high pump efficiency.
Pump with safety valve as overload protection, safety valve full back pressure of the pump rated exclusion pressure of 1.5 times, but also allows the discharge pressure within the scope of the actual need to be adjusted. But note that the safety valve can not be used for long-term work of the valve, if necessary, can be installed separately in the pipeline.
From the spindle extension to the pump to see, clockwise rotation.
CBQ series gear pump is a high performance gear pump. With small size, light weight, good performance, reliable, long life and so on. Widely used in construction machinery and other equipment.
The ROTAN internal gear pump offers favorable flow conditions because only a slight adjustment of the pump is required to change the flow direction. This means superior self-priming capacity and smooth delivery while delivering high viscosity media.
â—† scope of application
BCB series cycloid internal gear pump
For conveying solid particles and fibers, non-corrosive, the temperature is not higher than 150 ℃, the viscosity of 5-1500cst of lubricating oil or other liquid of similar nature.
â—† use
In the oil transmission system for transmission, booster pump.
In the fuel system can be transported, pressurized, jet fuel pump.
In all areas of work, can be used for lubricating oil pump.
â—† structure type
1, This series of gear pump gear, shaft, pump body, pump cover, shaft seal and other components, with cycloidal arc as a gear-shaped. Made of wear-resistant powder metallurgy material. Its compact structure, smooth operation, high efficiency, long life.
2, shaft end; Adopt the patented sealing technology (external bellows mechanical seal) patent number (ZL200520118516.2) developed by our company, without any leakage during use, shelf life: 1-3 years, without any maintenance in the middle
