What are the functions of hydraulic gear pump springs

A、 Advantages of springs 1. Ensure the stability of pump operation: The presence of springs can make the speed of gears more stable, thereby ensuring the normal operation of the pump. 2. Greatly enhances the pump's anti-interference ability: Gear pumps inevitably encounter external disturbances during operation. Without the support of springs, gears will be susceptible to disturbances and unable to function properly. With the support of springs, gear pumps can better resist such disturbances, thereby ensuring the stability and efficiency of the pump. 3. Reduce pump noise: Springs can reduce the impact noise between gears and pump bodies, thereby reducing the overall noise of the pump.

B、 The mechanism of action of springs The main function of the spring in the hydraulic gear pump is to adjust the tooth clearance and ensure the normal operation of the pump. When the pump is running, due to the influence of the load on the gears, small displacements will occur, resulting in changes in the tooth clearance between the gears and the pump body. And the spring is designed to adapt to this change through compression and elongation, maintaining a constant gap between the tooth tips.

C、 Material selection and maintenance of springs 1. Material selection of springs: The spring material in gear pumps is usually high-quality spring steel, which has a relatively high elastic modulus and tensile strength, as well as good compatibility and corrosion resistance. 2. Spring maintenance: When using a gear pump, it is necessary to regularly check whether the spring is deformed or damaged. If any problems are found, they should be replaced in a timely manner to ensure the normal operation of the pump.
