The Speed Increasing Gearbox for pumps is a key transmission component that connects the power source and pump equipment. It increases the input speed to the working speed required by the pump body through the principle of gear meshing, ensuring that the fluid conveying equipment operates efficiently under high pressure and large flow conditions.

Its design focuses on matching the power requirements of various pumps and is the core component for realizing speed regulation and power transmission in fluid mechanical systems.

High-efficiency transmission performance

Adopting high-precision gear processing technology (tooth surface accuracy reaches IT5 level), combined with high-strength alloy materials, the transmission efficiency is stable at 94%-98%, which can reduce power loss.

Wide range adaptability

Supports input speed of 500-3000rpm, output speed can be increased to 1500-12000rpm, adapts to various pump types such as centrifugal pumps, screw pumps, reciprocating pumps, etc., and the pressure adaptation range covers 0.1-30MPa, meeting the working conditions of different flow and pressure levels.

Durability and stability

The gears are carburized and quenched (surface hardness HRC58-62), the tooth root bending strength reaches 1200MPa, and the contact fatigue strength reaches 1800MPa, which prolongs the service life

The labyrinth seal structure is adopted, and the leakage protection level reaches IP65, which is suitable for complex environments such as humidity and dust

Structural optimization design

The modular assembly structure is 15%-20% smaller in volume and 10%-15% lighter in weight than traditional Gearboxes, which is convenient for installation in small spaces. The standard flange interface is compatible with multiple installation standards such as ISO and ANSI, reducing the cost of adaptation and transformation.

Petrochemical industry:

Crude oil delivery pumps and chemical medium circulation pumps need to increase the flow rate of viscous media under high pressure. The gearbox can increase the motor speed by 3-5 times to meet the pressure requirements of long-distance pipeline transportation.

Municipal water treatment:

The sludge return pump of the sewage treatment plant and the booster pump of the water plant can stabilize the outlet pressure by speed adjustment when the processing volume fluctuates, reducing the impact of the pipeline network.

Power industry:

The boiler feed water pump of the thermal power plant and the circulating water pump of the nuclear power plant need to maintain a stable flow rate under high temperature and high pressure environment. The temperature resistance design of the gearbox (-40℃ to 120℃) can adapt to harsh working conditions.

Metallurgical manufacturing:

Blast furnace cooling water pump, steel rolling emulsion pump, the anti-vibration performance of the gearbox (amplitude ≤ 0.08mm) can adapt to the high-frequency vibration environment of the workshop equipment

Installation points:

The flatness error of the base installation surface must be ≤0.1mm/m. Use a level to calibrate to ensure that the coaxiality of the gearbox, power source, and pump body is ≤0.05mm.

The connecting bolts must be tightened evenly (the preload force complies with GB/T 1231 standard), and anti-loosening washers are installed to prevent vibration and loosening.

Check the lubrication system: Fill N320 extreme pressure industrial gear oil to the center line of the oil level gauge before first use. Different brands of oil cannot be mixed.

Startup and operation:

Run the test run at no load for 10-15 minutes to check for abnormal noise (normal operating noise ≤85dB) and oil leakage.

Gradually load to rated working conditions, monitor the oil temperature in real time (stop for inspection if it exceeds 85℃) and the bearing temperature (≤95℃).

Record the operating parameters (speed, temperature, vibration value) every 8 hours during continuous operation.

Daily maintenance:

Regular maintenance: Run 2000 Replace gear oil every 12 hours (filtration accuracy ≥ 10μm), clean oil filter; check gear meshing clearance every 5000 hours (standard value 0.15-0.3mm)

Check seals every 12 months, and replace immediately if aging or damage is found (fluoro rubber seals are recommended)

Long-term shutdown (more than 30 days) requires manual turning 1-2 times a week to prevent bearing corrosion
