The invention discloses an anti-freezing crew-pump capable of increasing the flow velocity of a liquid in a pump. The anti-freezing crew-pump comprises a universal shaft, a universal shaft seat and a screw rod which are sequentially connected, wherein a hole is punched in the extension direction from the connected part of the universal shaft seat and the screw rod to the screw rod, and an electric heating wire is arranged in the hole; the electric heating wire passes through the universal shaft seat and is connected with an electric heating interface in the universal shaft seat. Through the method of arranging the electric heating wire in the screw rod, power supply of the electric heating interface is connected when the environment temperature is too low, and the electric heating wire works and heats the screw rod, so that the liquid in a screw pump is heated and the temperature of the liquid is ensured. The anti-freezing crew-pump has the advantages that the temperature of the liquid in a pump body can be kept, solidification of the liquid is avoided, and the anti-freezing crew-pump is provided with a water cooling pipe, thereby facilitating cooling or heating.
