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
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.
What are the conditions for good starting performance of excavators?
- There must be enough starting speed. The high starting speed means less gas leakage in the cylinder, shorter heat transfer time of compressed air to the cylinder wall, less heat loss, and higher gas temperature and pressure at the end of compression. Generally, the speed is required to be above 100r/min.
2. The cylinder should have good sealing. This can further reduce the amount of leakage and ensure that the gas has sufficient combustion temperature and pressure at the end of compression. The compression pressure of the cylinder shall not be lower than 8_0_%_ of the standard value.
3. The engine is required to have appropriate clearance relative to the running parts and good lubrication.
4. The battery must have sufficient starting capacity and the technical condition of the starting circuit is normal.
5. The starting oil volume meets the requirements, the injection quality is good, and the injection advance angle meets the requirements.
6. Use fuel that meets the requirements
How do you prevent cavitation in a hydraulic pump?
Ways to prevent cavitation include maintaining the proper hydraulic oil level, using the correct oil viscosity, ensuring the filter is clean and avoiding excessive loads on the hydraulic system.
What are the reasons for the excavator crawler chain off?
1. Chain off caused by tension cylinder failure
At this time, you should check whether you have forgotten to butter the tension cylinder and see if there is any oil leakage in the tension cylinder.
2. Chain off caused by severe wear of the crawler
If used for a long time, the crawler will definitely be worn, and the wear of the chain ribs, chain barrels and other parts on the crawler will also cause the crawler chain off.
3. Chain off caused by wear of the chain guard
Now almost all excavator crawlers have chain guards, and chain guards can play a very important role in preventing chain off, so it is also very important to check whether the chain guard is worn.
4. Chain off caused by wear of the drive motor ring gear
For the drive motor ring gear, if it is severely worn, we need to replace it, which is also an important reason for the excavator chain off.
5. Chain off caused by damage to the sprocket wheel
Generally speaking, oil leakage of the sprocket wheel oil seal of the excavator will cause severe wear of the sprocket wheel, which will cause the crawler chain off. The public account Zhizao Daguan focuses on sharing relevant theoretical knowledge in the engineering machinery manufacturing industry.
6. Chain derailment caused by guide wheel damage
When checking the track guide wheel, check whether the screws on the guide wheel are missing or broken. Check whether the groove of the guide wheel is deformed.
How to maintain the excavator's swing bearing?
Regularly lubricate the swing bearing, check if the grease is sufficient, inspect the bearing for wear or looseness, and adjust or replace it if necessary.
