Provide stable pressure for the injection molding process to ensure the quality of plastic product molding; During die-casting, assist in accurately filling the mold cavity with molten metal to improve the precision of die-casting products.

3. * * Agricultural Machinery * *: Used for tractors, harvesters, and other agricultural machinery, providing power support for various movements of agricultural machinery in farmland operations, adapting to complex and changing farmland environments, and helping to promote efficient and mechanized agricultural production.

##3、 Product Features

1. * * Efficient and energy-saving * *: Adopting advanced gear meshing design to reduce internal leakage, the volumetric efficiency is as high as [X]% or more. Compared with similar products, it can reduce energy consumption by [X]% under the same working conditions, effectively reducing operating costs.

2. * * Durable * *: The key components are made of high-quality alloy steel materials, which have undergone special heat treatment processes, resulting in high surface hardness and strong wear resistance. The body components of the gear pump are integrally extruded under a pressure of 3600 tons, with a compact structure that can withstand working pressures up to [X] MPa, adapt to harsh working conditions, and have a service life of over [X] hours.

3. * * Low noise and stable * *: Optimized gear parameters and pump body structure, with low vibration and noise as low as [X] dB (A) during operation, ensuring a quiet and comfortable working environment while ensuring smooth equipment operation and reducing damage to other components caused by vibration.

4. Strong adaptability: With a wide range of model specifications, it can meet different flow and pressure requirements. The displacement range covers - mL/r, and the rated pressure ranges from [* low rated pressure] MPa to [maximum rated pressure] MPa. It can be matched with various hydraulic systems, making it convenient for customers to choose.

5. * * Convenient maintenance * *: Open design concept, some components can be disassembled and replaced separately, without the need to disassemble the pump body as a whole, greatly reducing maintenance time and lowering maintenance costs. At the same time, vulnerable parts have strong universality and are easy to purchase in the market.

##5、 Model Selection Guide

1. * * Determine flow demand * *: Based on the required hydraulic oil flow rate during equipment operation, combined with factors such as working cycle time, calculate the required gear pump flow rate for the system.

2. * * Clarify pressure requirements * *: Consider the pressure requirements of the equipment under normal operation and possible peak working conditions, and select a gear pump model that can meet the requirements for both rated pressure and maximum pressure.

3. * * Consider installation space and connection method * *: Measure the space size of the equipment that can be used to install the gear pump, and choose a model that fits the external dimensions. Meanwhile, based on the system interface form, determine the connection method of the gear pump, such as flange connection, threaded connection, etc.

4. * * Speed matching * *: Ensure that the rated speed of the selected gear pump matches the output speed of the equipment drive device, to avoid affecting the performance and service life of the pump due to speed mismatch.

##6、 Production process and quality control

Komatsu gear pumps strictly follow production process standards during the production process. Starting from the raw material procurement process, strict quality inspection is carried out on each batch of steel to ensure that the material performance meets the design requirements. During the component processing stage, high-precision machining equipment is used to ensure that the machining accuracy of key components such as gears and shafts is controlled within ± [X] mm. The assembly process is carried out in a dust-free and constant temperature environment, operated by experienced technicians according to standardized operating procedures to ensure that each component is installed in place. Before leaving the factory, the product needs to go through multiple strict quality inspection processes, including performance testing, pressure resistance testing, leakage testing, etc. Only products that pass 100% of the tests can enter the market.

##7、 After sales service
