Puffing machinery and equipment has been widely used in the field of raw material pretreatment, maintenance should not be ignored, mainly to grasp the following aspects of the problem:.
1, puffing equipment extruding machine to ensure that the host oil tank oil level to reach the premise that the host must start the oil pump before starting, to stop the oil pump only after the host has stopped to protect the spindle bearings, and to avoid prolonged idling of the host.
Generally not more than 60 seconds.
2, puffing equipment extruding machine in the host idle or start must ensure that the screw in the process of operation and puffing cavity wall without any touching sound. If the puffing cavity offset, the screw in the running process with the puffing cavity friction impact, will greatly affect the service life of the screw, and even directly break the screw, but also make production instability, affecting output.
Each time the replacement screw or disassembly of the expansion cavity need to adjust the expansion cavity. Adjustment method: the puffing cavity is fixed in a suitable position through the puffing cavity support, and the puffing cavity support can be adjusted up and down and left and right, adjusted by the two sides of the "horizontal limit bolts" and up and down direction of the four "upper and lower limit bolts" When adjusting the empty machine, the gap will be adjusted evenly in the left and right directions, and the gap above is slightly larger than the gap below (about 0.5-1mm), and the ф195㎜ pressure ring can be installed for reference; when the material enters the cavity, the screw will float slightly, making the gap basically the same without any touching sound, and the nut on the limit bolt must be fixed after the adjustment.
3, puffing equipment extruding machine replacement screw configuration, do not knock the screw and puffing cavity and bushing, each screw, pressure ring, bushing and adjusting spacer end face must be clean, while the spindle cleaned and coated with lubricant for disassembly.
4, puffing equipment extruding machine production process must ensure a continuous supply of materials, broken material and a sudden increase in the amount of material are prone to blocking the machine, the amount of steam supply also needs to be relatively stable.
5, puffing equipment extruding machine check whether the actual current of the host and the current meter shows the same current, regularly check the tightness of the host belt, generally 29Kg of force acting on the midpoint between the two pulleys to press down one of the belts, the belt down 14㎜ (that is, basically a belt thickness) is appropriate, otherwise it needs to be adjusted.
6、Extruding machine when accidentally blocking the machine can not start the main engine, it is recommended to solve the problem according to the following measures, until the main engine rotates.
①, disassemble the last section of the puffing cavity after the point of the host.
②, the use of special tools set on the lever or remove the main motor shield, artificial positive and negative direction of rotation of the main pulley.
③, such as still can not turn the need to disassemble the puffing cavity to try to turn, until the material cleaned up. According to the specific circumstances can also add steam to each jacket to raise the temperature of the puffing cavity carbonized cavity materials.
7, puffing equipment extruding machine equipment lubrication.
①, puffing cavity main bearing lubricant lubrication
Recommended lubricant name and code: ISO-VG68 bearing oil (room temperature ≥ 0 ℃)
ISO-VG32 bearing oil (-8 ℃ ≤ room temperature ≤ 0 ℃)
The new oil must be replaced regularly in the bearing housing and oil tank. The first oil change is 500 hours of work with all new oil, and then the oil is replaced once a year. The specific replacement method and details are shown in the TPH200 Installation and Operation Maintenance Manual.
②, other parts, every 48 hours of work, grease injection once, the recommended grease name and code: calcium-based grease ZG3 (GB491-1987).
Other parts are mainly
A. Bearings at both ends of the feeder shell (2 places).
B, the temperer motor (1 place).
C, both ends of the temperer shell bearings (2 places).
D, puffing machinery and equipment main motor (2 places).
E, feed puffing cavity and bearing seat connection side of the oil cup refueling port (1 place).
F, cutting device motor (2 places).
8, puffing equipment extruding machine to keep the puffing machine and its surrounding sanitation and cleanliness
