What is a Hydraulic Pump: Everything You Need to Know
In the world of heavy machinery, hydraulic pumps play a pivotal role. From construction sites to manufacturing plants, these mechanical wonders are the unsung heroes that keep our industrial world moving. But what exactly is a hydraulic pump, and why is it so crucial in today’s machinery landscape? In this comprehensive guide brought to you by Kyotechs, we will delve deep into the intricacies of hydraulic pumps and their significance in various applications.
What is a Hydraulic Pump?
A hydraulic pump is a mechanical device that converts mechanical energy into hydraulic energy. It generates flow with enough power to overcome pressure induced by the load. The purpose of a hydraulic pump is to move hydraulic fluid from the reservoir to the rest of the hydraulic circuit. This movement of the hydraulic fluid accomplishes work such as lifting, pushing, steering, and moving heavy machinery in a controlled manner.
How Does a Hydraulic Pump Work?
The operation of a hydraulic pump is straightforward yet fascinating. When powered, typically by an electric motor or engine, the pump creates a vacuum at its inlet, forcing hydraulic fluid from the reservoir into the inlet line. The pump then mechanically transports the fluid to the outlet, generating the flow and pressure necessary to produce mechanical work.
Types of Hydraulic Pumps
There are several types of hydraulic pumps, each designed for specific applications:
1. Gear Pumps: Simple in design and highly reliable, these pumps are mainly used in industrial applications.
2. Vane Pumps: Known for their efficiency, these are used in medium-pressure applications.
3. Piston Pumps: Ideal for high-pressure applications, these pumps are often used in heavy machinery.
4. Axial and Radial Piston Pumps: Known for their compact design and are ideal for high-efficiency power transmission.
Benefits of Hydraulic Pumps
Hydraulic pumps are essential in a wide range of applications due to their numerous benefits, including:
- Efficiency: They convert energy with minimal losses.
- Precision: These pumps offer precise control of movement, essential for machinery accuracy.
- High Power Density: Capable of delivering substantial power from a compact device.
- Durability: Designed to withstand harsh environments and demanding tasks.

FAQS
What are the common faults of crawler excavator hydraulic pumps?
Common faults of hydraulic pumps include insufficient pressure, hydraulic oil leakage, abnormal noise, system overheating and wear of internal pump components.
How to adjust the tension of the tracks?
To adjust the track tension, refer to the specific operation manual for the excavator model. Generally, this is done by adjusting the bolts on the tension cylinder or increasing/decreasing the pressure of the tension spring.
How to test the system after the hydraulic pump is replaced?
The way to test the system after replacement is to start the excavator, slowly operate all hydraulic functions, check system pressure, leakage and operation, and ensure that everything is normal.
When does the battery in use need to be recharged?
When the battery liquid specific gravity is lower than 1.15 or the single cell voltage is lower than 1.7V (V), or when changing seasons for maintenance, it should be removed for recharging and the liquid specific gravity should be adjusted. If it needs to be parked for a long time, it should be fully charged and stored, and recharged once a month. If it needs to be stored for a long time, it should be fully charged, all the liquid should be poured out, and the filling port should be sealed for storage. When it needs to be used, re-add the electrolyte that meets the requirements.
Which oil level is the most suitable for the oil cylinder?
There are usually the highest and lowest oil level marks (MAX and MIN) on the inner wall of the oil filling port of each engine. This means that the oil level cannot exceed MAX or be lower than MIN.
A lower oil level, that is, a decrease in the amount of oil in the engine, will increase the oil load, causing the oil to become more seriously contaminated by heat, which not only weakens the lubrication performance, but also increases the fuel consumption. Because the less oil in the engine, the higher the oil temperature; and the higher the oil temperature, the greater the fuel consumption will be as the oil temperature rises. It is very dangerous to run the engine when the oil level is at the lowest point (MIN).
Keeping the oil level at the highest point (MAX) all the time will cause the oil to foam and lead to insufficient lubrication, resulting in serious wear. Foaming oil will also increase fuel consumption.
Therefore, it is recommended to keep the engine oil level between the MAX and MIN marks at a position close to one-third of the MAX.
