Problems solved by technology

[0002] Due to the high viscosity of the syrup, the delivery pump needs to have a large power during the delivery, and if the delivery pump stops, the syrup remaining in the delivery pump will cool down and the viscosity will further increase. When the delivery pump is started next time, it will be due to the The pressure difference between the inlet and outlet is too large and the shaft is broken or the motor is burnt out

Abstract

The invention discloses a syrup delivery pump. The syrup delivery pump comprises a pump body and a return pipe, wherein a feeding pipe and a discharging pipe are arranged on the pump body; one end of the return pipe is connected with the feeding pipe of the pump body, and the other end of the return pipe is connected with the discharging pipe of the pump body; a valve for controlling connection between the return pipe and the feeding pipe and the discharging pipe of the pump body is arranged on the return pipe. Due to the arrangement of the return pipe, some syrup can enter a discharging end from a feeding end through the return pipe when the delivery pump is started, so that the pressure of the delivery pump is relieved; in addition, when few materials are demanded, pumped syrup partially returns to the feeding end from the return pipe to relieve the pressure of a material using end, so that the possibility of damage of the delivery pump is greatly lowered, and the delivery pump is unlikely to be damaged.

Description

technical field [0001] The invention relates to a pump, in particular to a syrup delivery pump. Background technique [0002] Due to the high viscosity of the syrup, the delivery pump needs to have a large power during the delivery, and if the delivery pump stops, the syrup remaining in the delivery pump will cool down and the viscosity will further increase. When the delivery pump is started next time, it will be due to the If the pressure difference between the inlet and outlet is too large, the shaft will be broken or the motor will be burnt out. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a syrup delivery pump that is not easily damaged. [0004] In order to solve the above technical problems, the present invention includes a pump body, the pump body is provided with a feed pipe and a discharge pipe, and also includes a return pipe, one end of the return pipe is connected to the feed pipe of the pump bod...
