Advantages of Hydraulic Gear Pump

High efficiency

Hydraulic gear pumps can achieve higher flow and pressure at lower energy consumption, which improves the working efficiency of the hydraulic system.

Widely used

Hydraulic gear pumps can be used in various hydraulic systems, such as engineering machinery, agricultural equipment, hydraulic tools, etc., with strong adaptability.

Simple structure

Its design is relatively simple, easy to manufacture and maintain, and reduces production and maintenance costs.

High reliability

Good sealing and wear resistance enable hydraulic gear pumps to work stably in harsh environments.

Applications of Hydraulic Gear Pump

Production of Oil and Gas

In the oil and gas sector, hydraulic gear pumps play a crucial role in the movement of fluids between sites, including gas and oil. They are able to transfer fluids, for instance, from wellheads to storage tanks.

Water Treatment

To ensure a steady flow of water for processing, these pumps are utilized in water treatment systems to move water from sources like rivers or lakes into municipal wastewater treatment plants.

Mining

A vital part of the extraction and transportation process, hydraulic gear pumps are used in the mining sector to move commodities, such as coal, from mine sites to processing facilities or other destinations.

Hydraulic Gear Pump Assembly Steps

Clean all parts
Clean all parts with a lint-free cloth. Even new parts may have dust or protective grease on them, which should be removed before assembly.

Install bushings or bearings
Press bushings or bearings into the front and rear covers. Make sure they are fully seated and aligned. Use a bearing press or hydraulic press if necessary.

Insert the gear train
Place the gear train into the housing:
The drive gear is connected to the input shaft.
The driven gear rotates with the drive gear.
Make sure both gears mesh smoothly and rotate freely in the housing.

Insert the shaft and seals
Insert the drive shaft into the corresponding gear. Install the shaft seal into the front cover or bearing housing. Make sure the seal lip faces inward to retain oil.
Apply a small amount of clean hydraulic oil to the shaft to make insertion easier.

Precautions for Using Hydraulic Gear Pumps

Regular Lubrication
To minimize wear and tear, it is essential to lubricate these pumps regularly. The lubricating oil film helps prolong the lifespan of the components. However, it is equally important to keep the connection points clean to prevent contamination.

Routine Inspection and Maintenance
Periodic checks are necessary to ensure the pump’s optimal performance. Key areas to inspect include the condition of critical components like bearings, as well as the tightness of internal wiring and connectors.

Proper Installation

Ensure that the pump is installed correctly, with proper alignment and secure connections. Misalignment can lead to premature wear and reduced efficiency.

Monitor Operating Conditions

Keep an eye on the pump’s operating temperature and pressure. Excessive heat or pressure can damage the pump and reduce its lifespan. Using a pressure gauge and temperature sensor can help in monitoring these parameters.

Use High-Quality Hydraulic Fluid

The quality of the hydraulic fluid used in the system plays a significant role in the pump’s performance and longevity. Always use fluids that meet the manufacturer’s specifications.

Ordering Process

Inquiry - quotation - communication - order confirming - deposit payment - production - testing and debugging - balance payment - packing - delivery - customer receiving - after service.

FAQ

Q: How does a hydraulic gear pump work?

A: Gear pumps use the actions of rotating cogs or gears to transfer fluids. The rotating element develops a liquid seal with the pump casing and creates suction at the pump inlet. Fluid, drawn into the pump, is enclosed within the cavities of its rotating gears and transferred to the discharge.

Q: How to tell if a hydraulic gear pump is bad?

A: Pump turns, but no flow.
Low capacity.
Pump will not develop sufficient pressure.
Pump develops too much pressure.
Pump no longer self-priming.
Pump won't turn/ motor stalls.
Pump runs noisy with excessive vibration.
Pump runs hot.

Q: What is the life expectancy of a hydraulic gear pump?

A: The life expectancy of a hydraulic pump isn't typically measured in years, but rather in hours. On average, the following tends to be true: Gear pump – 10,000 – 15,000 hours (equating to around 5-7 years of use) Vane pump – 12,000 – 18,000 hours (equating to around 6 to 9 years of use)

Q: How to test a hydraulic gear pump?

A: Verify flow under load.
Monitor case drain flow & temperature.
Track motor current draw.
Apply thermodynamic testing for precision.
Prioritize safety first.
Start with basic inspections.
Add a flow meter at the relief valve.
Monitor case drain flow & temperature.

Q: How do you maintain a gear pump?

A: Check bearings regularly. The bearings are the most important area to maintain because they can cause imbalance if misplaced or defective. Check bearings regularly and replace as necessary by removing the defective bearing with a puller. Excessive noise can be an indication of bearing wear.
