The gear oil pump is used to provide hydraulic power to drive the hydraulic systems of agricultural and construction machinery to perform various work tasks such as lifting, tilting and turning. The oil outlet pipe is an important component of the gear oil pump. Its main function is to transport the lubricating oil pressurized by the gear oil pump from the inside of the pump body to the lubrication system or equipment that needs lubrication.

The unstable oil pressure may affect the normal operation of the lubrication system, resulting in insufficient lubrication and excessive lubrication, causing damage to the equipment. In addition, during the delivery of the lubricating oil, the noise generated inside the oil pump is relatively large. Therefore, it is particularly important to design a low-noise gear oil pump.
