In modern agricultural machinery, two vital components are hydraulic gear pumps and agricultural gear pumps. These pumps play crucial roles in powering the various hydraulic systems found in agricultural equipment. While both types of pumps serve similar purposes, there are key differences between them. Functionality and Application. Hydraulic gear pumps are primarily used in hydraulic systems that require high-pressure fluid delivery, such as excavators, loaders, and hydraulic presses. Their main purpose is to transfer power from the engine to the hydraulic system, providing the necessary force to control the machinery's various functions. On the other hand, agricultural gear pumps are specifically designed to meet the unique demands of agricultural equipment, such as tractors, harvesters, and sprayers. They are responsible for powering hydraulic systems used for lifting, steering, and operating different agricultural implements. Design and Construction. Both hydraulic gear pumps and agricultural gear pumps consist of gears that rotate and trap fluid between the teeth of the gears, generating pressure and transferring the fluid. However, the design and construction of these pumps differ to suit their specific applications. Hydraulic gear pumps are typically built with robust materials and precise machining to handle high pressures and provide long-lasting performance. Agricultural gear pumps, on the other hand, are often designed to be more compact and lightweight, considering the space and weight limitations of agricultural machinery. Pressure and Flow Rate. Hydraulic gear pumps are known for their ability to generate high pressure, typically ranging from 1000 to 5000 psi, making them ideal for heavy-duty hydraulic applications. Agricultural gear pumps, on the other hand, generally operate at lower pressures, ranging from 500 to 2000 psi, as the agricultural machinery often requires less force. While hydraulic gear pumps deliver higher pressure, agricultural gear pumps are designed to provide higher flow rates to meet the demands of agricultural equipment. Efficiency and Performance. Hydraulic gear pumps are known for their high mechanical efficiency, often exceeding 90%, resulting in ideal power transmission. Agricultural gear pumps, while slightly less efficient than hydraulic gear pumps, still offer a good level of efficiency, ensuring adequate power delivery to operate agricultural machinery effectively. Maintenance and Reliability. Proper maintenance is crucial to ensure the longevity and reliable performance of gear pumps. Hydraulic gear pumps often require regular maintenance due to the higher pressures and loads they experience. However, with proper maintenance and timely replacement of worn components, they can provide reliable operation for an extended period. Agricultural gear pumps, designed for the specific demands of agricultural settings, are often more resilient and require less frequent maintenance, making them a practical choice in the field. In conclusion, both hydraulic gear pumps and agricultural gear pumps play vital roles in powering hydraulic systems in modern agricultural machinery. While hydraulic gear pumps are capable of higher pressures, agricultural gear pumps are designed for agricultural applications with suitable flow rates. Each type of pump has its advantages and limitations, and considering their specific functional requirements is crucial when choosing the appropriate pump for agricultural equipment. Understanding the similarities and differences between hydraulic gear pumps and agricultural gear pumps enables farmers and machine operators to make informed decisions to ensure the desired performance and service life of their machinery....

We all know that the hydraulic gear pump is the power component of the entire system, but some users find that the pressure does not rise when the pump is turned on during use. According to user analysis, the pump has internal leakage and cracks. So today I will talk to you about the reasons and solutions for these two failures. Let's find out together! 1. Reasons for the leakage of hydraulic gear pump 1. The end face is leaking. This is the gap between the end face of the gear and the end thrust plate and is the cause of pump leakage. This place also occupies a large proportion of leakage. Therefore, wear of the thrust plate or floating bushing may cause leakage. increase pressure, which affects pump displacement and pressure; 2. Radial leakage. This kind of leakage refers to the leakage between the tooth top circle of the gear and the surface of the pump body cavity, and the wear of the tooth top or the pump cavity is aggravated, resulting in leakage; 3. The meshing line leaks, and the full-width meshing of the gear cannot be realized. The resulting leakage is called mesh line leakage, and the tooth surface is severely worn, resulting in increased leakage; Solution: replace or repair thrust plate, replace or repair gear, replace or repair gear. 2. Reasons for cracks in the hydraulic gear pump body 1. Caused by improper installation of the pump; 2. The pump is suffocated by high pressure; 3. There is a problem with the screw pre-tightening torque, which leads to excessive stress and damage; Solution: replace the new pump, install it according to the instructions, adjust the pump pressure, and adjust the screw preload torque. The above content is the reason for the internal leakage of the hydraulic gear pump shared by Xiaobian and the cracks in the pump body. If the pump we use has these two situations, then we may try the reasons compiled by Xiaobian to solve the problem. Failed, hope to help everyone.
