Zusammenfassung: | The utility model provides a torpedo injection pump, which relates to the field of injection pumps and comprises a shell, an injection component, a motor coding component, a push rod and a self-lubricating graphite sleeve, and the push rod and the self-lubricating graphite sleeve are mounted in the shell and connected between the injection component and the motor coding component. The other end of the self-lubricating graphite sleeve is in transmission connection with an output shaft of the motor coding assembly through a transmission connecting piece; when the motor coding assembly is started, the transmission connecting piece can drive the push rod to move along the self-lubricating graphite sleeve and push the injection assembly to perform reciprocating extraction. Through the self-lubricating graphite sleeve, the push rod of the pump body has a self-lubricating function, and a complex lubricating oil device does not need to be additionally adopted to reduce the friction force of the push rod in the moving |
