Later our technicians recommended CX-KCB-300 gear oil pump to him

 

When selecting a gear oil pump, you need to consider multiple aspects to ensure that the selected pump can meet the specific application requirements. Here are some key selection steps and considerations:

 

1. Clarify application requirements

 

Medium characteristics:

 

Viscosity: Understand and determine the viscosity range of the required conveying medium. For high viscosity media, you need to select a gear oil pump that can handle this viscosity, and pay attention to the drive configuration of the pump, such as selecting a belt reduction or an adjustable frequency motor.

 

Temperature: Determine the temperature range of the medium. Generally speaking, the delivery temperature of the gear oil pump should not be higher than 70°C. For high-temperature media, a pump body of special materials or structures needs to be selected to ensure its normal operation.

Corrosiveness: eva luate whether the medium is corrosive to select the appropriate pump body and sealing materials. Stainless steel is suitable for the delivery of corrosive fluid media.

Flammability: For flammable and explosive media, it is necessary to select an explosion-proof gear oil pump, and select an explosion-proof motor or a common motor according to the flammability of the medium.

Flow and pressure requirements:

Flow: Determine the required flow size according to system requirements, usually in liters/minute (L/min) or cubic meters/hour (m³/h). Flow requirements will directly affect the selection and configuration of the pump.

Pressure: Determine the required working pressure range of the system and select a gear oil pump with sufficient pressure capacity.

2. Material selection

 

Pump body material:

Select the appropriate pump body material according to the nature of the medium. Cast iron material is suitable for the delivery of lubricating fluid media under ordinary industrial conditions; stainless steel material is suitable for the delivery of corrosive fluid media.

For special media, such as high temperature or high pressure media, it is necessary to select special materials that are resistant to high temperature and high pressure.

Sealing materials:

The selection of sealing materials depends on the characteristics of the media and the working pressure. Mechanical seals are suitable for occasions that require high sealing reliability, while packing seals are suitable for high temperature oil pumps.

For non-lubricated, low viscosity media, it may be necessary to select special sealing forms or enhance the reliability of the seal.

 

III. Structure and performance parameters

 

Gear type:

Different types of gear pumps have different performance characteristics. The involute gear pump has a simple structure, is easy to manufacture and maintain; the arc gear pump has higher transmission efficiency and lower noise.

Select the appropriate gear type according to the medium delivery requirements and the system performance requirements.

Speed ​​and power:

The speed selection should be determined according to the working conditions and system requirements. High speed can increase the flow rate of the pump but may increase noise and wear; low speed may reduce the flow rate of the pump but reduce noise and wear.

The power is closely related to the pump flow, pressure, speed and other parameters, and needs to be selected according to actual needs.

Efficiency and precision:

Selecting a high-efficiency pump can reduce energy consumption and heat loss and improve the overall efficiency of the system.

If you have high requirements for the control accuracy of flow and pressure, you need to choose a gear oil pump with the corresponding accuracy level.

 

Self-priming ability: If the application requires the pump to have self-priming ability, you should choose a pump with this function.

Explosion-proof requirements: As mentioned above, for occasions where flammable and explosive media are transported, you need to choose an explosion-proof gear oil pump.
