Oil Pump Types Introduction
There are many types of oil pumps, which can be divided into many types according to different classification standards. The following is a detailed introduction to the classification of oil pumps from different angles:
1. Classification by function and application field
Injection pump:
It is mainly used in modern automobile diesel engines and is one of the core components of diesel engines.
The injection pump assembly is usually composed of injection pumps, speed regulators and other components installed together, and its operating status directly affects the overall performance of the diesel engine.
Once there is a problem with the injection pump, the diesel engine may not work properly.
Self-priming oil pump:
It has a unique self-priming function, which can gradually exhaust the air in the suction pipeline through repeated cycles, so that water or other liquids can enter the pump smoothly.
This feature makes the self-priming oil pump irreplaceable in certain specific occasions (such as occasions where self-priming function is required).
Submersible oil pump:
It is mainly composed of pump shaft, impeller, guide casing, pump casing and other components, which can adapt to different types of oil well environments.
Its stability and durability are widely used in fields such as oil extraction.
Oil pump:
It is mainly used in various mechanical equipment to provide stable and reliable lubrication effect for the equipment.
The oil pump is driven by an electric motor and consists of a pump sleeve, an end face housing, a rotor and a rotor elastomer.
All its friction contact surfaces are made of highly wear-resistant materials, so they have extremely strong wear resistance and long life.
2. Classification by mechanical structure
In-line oil pump:
The plungers of this type of oil pump are arranged in a row, and the structure is relatively simple. It is suitable for some occasions where the performance requirements of the oil pump are not particularly high.
Distributor oil pump:
The plungers of the distributor oil pump are distributed in a circle, and the high-pressure oil is distributed to each cylinder through a specific distribution mechanism.
This oil pump has a compact structure and stable performance, and is widely used in modern automobile diesel engines.
Monomer oil pump:
Monomer oil pump usually refers to a single independent oil pump unit, which may contain some of the above functions (such as self-priming, fuel injection, etc.) and is installed on the mechanical equipment as an independent component.
3. Other classification methods
Oil pumps can also be classified according to other characteristics, such as according to the driving mode (electric, hydraulic, etc.), according to the working pressure (high pressure, low pressure, etc.), according to the conveying medium (heavy oil, diesel, lubricating oil, etc.), etc. These classifications help to provide a more comprehensive understanding of the types and characteristics of oil pumps.
