The oil gun and ignition gun propulsion device is one of the executive mechanisms for programmed ignition. This mechanism can send the oil gun and ignition gun into or out of the furnace at a certain speed under the command of the control system. It has the advantages of superior performance, reasonable structure, flexible and reliable operation, and easy to achieve automatic control. XTJ propulsion devices have now formed a series, which can be divided into two types according to the driving mode: electric and pneumatic; According to the structural form, it can be divided into monomer and combination.

1. XTJ-1 electric thruster

(1) Product Introduction

Working principle: The motor transmits its torque to the lead screw through a coupling, thus realizing the process of turning the rotational motion of the motor into a linear motion. At the same time, the forward and reverse rotation of the motor is used to complete the forward and backward movements of the push rod.

Structure: Mainly composed of drive motor, lead screw, nut, travel switch, and other components.

Features: Compact structure, good performance, stable operation, low noise, small size, beautiful appearance, fully sealed dustproof structure, convenient installation, operation and maintenance, easy to control operation.
