The invention discloses a double-power parallel displacement delivery pump with the cooling function. The double-power parallel displacement delivery pump comprises an externally-arranged device and an internal device. A stainless steel tank body is arranged behind a stainless steel pump cover and connected with an outer shell through the stainless steel pump cover. A shaft bin is arranged behind the stainless steel tank body. A base support is arranged below the shaft bin and connected with the stainless steel tank body through the shaft bin. The internal device is internally provided with spiral rotors. A liquid-charged cooling sealing bin is arranged behind each spiral rotor and connected with the internal device through the corresponding spiral rotor. A front roller bearing is fixedly welded to the position behind each liquid-charged cooling sealing bin. A roller is arranged behind each front roller bearing in a movable manner. A rear roller bearing is arranged behind each roller. Each rear roller bearing is connected with the corresponding front roller bearing through the corresponding roller. The double-power parallel displacement delivery pump is provided with the liquid-charged cooling sealing bins, so that heat resistance of the spiral rotors is improved; the double-power parallel displacement delivery pump is provided with double driving shafts, so that kinetic energy efficiency is improved; and the double-power parallel displacement delivery pump is simple in structure and easy to implement.
