Advantages and Common Problems of Volvo Gear Pump

The Volvo excavator's gear pump is one of its key components, playing a crucial role in the machine's performance and efficiency. Many users may have questions about the Volvo gear pump's working principle, maintenance, and other aspects. Below we will address some common questions.

Volvo Gear Pump Common Questions

Q1: What is the working principle of the gear pump?

A1: The gear pump generates vacuum and pressure through two meshing gears, thus sucking in and discharging the liquid. This design provides the pump with efficient and stable working characteristics.

Q2: How to maintain and service theVolvo gear pump?

A2: Regularly replacing the lubrication oil, cleaning the pump body, checking the seals and filters, are key to ensuring normal operation of the gear pump. Additionally, avoiding overload operation can extend the pump's service life.

Q3: How to deal with abnormal noises in the gear pump?

A3: Abnormal noises may be caused by gear wear, insufficient lubrication, or foreign objects entering the pump body. Timely inspection, repair, and replacement of damaged parts are key to solving the problem.

Q4: What should be done in case of oil leakage from the gear pump?

A4: Oil leakage might be due to aging or damaged seals. Seals should be replaced promptly and the pump body should be checked for damage to ensure the leakage problem is resolved.

Q5: How to determine if theVolvo gear pump needs replacement?

A5: When the gear pump experiences frequent failures, decreased work efficiency, or abnormal noise, it may be time to consider replacing the pump body or key components. Regular inspections and maintenance can extend the pump's service life.

Volvo Gear Pump Working Principle

The working principle of the gear pump is based on the rotation and meshing of gears:

Suction Process

When the gears start rotating, a sealed working chamber (pump chamber) is formed between the two gears. As the gears separate, the volume of the pump chamber gradually increases, creating a low-pressure area. At this time, the liquid enters the pump chamber through the inlet pipe, filling the space within the pump chamber.

Discharge Process

As the gears continue to rotate, the meshing of the gears causes the volume of the pump chamber to gradually decrease, increasing the pressure. The liquid is pushed out of the pump chamber and discharged through the outlet pipe.

Sealing

The meshing of the gears creates a seal in the pump chamber, ensuring that the liquid is pushed through the pump chamber without leaking into the gaps between the meshing gears.

Volvo Gear Pump Advantages

• High cost performance: The gear pump features high output performance and low cost.

• Strong adjustability: The output pressure and flow rate of the gear pump are accurately adjusted by the pressure regulator of the drive gas. Adjusting the drive air pressure allows for precise adjustment of the output pressure of the pneumatic pipeline gear pump between the preset pressure and the maximum output pressure.

• High output pressure: The maximum working pressure of the pneumatic liquid pipeline gear pump can reach 700Mpa, while the pneumatic gas pipeline gear pump's maximum working pressure can reach 300 Mpa.

• Excellent material:The high-pressure parts of the Volvo gear pump are made of hard aluminum alloy. The high-pressure plunger is made of stainless steel and uses dual-layer sealing. The material of key parts can be selected based on the nature of the medium.
