"Longevity tips" for laboratory extruders"
The laboratory extruder wants to live longer and the daily maintenance work should be done well:
(1), check the lubrication parts at least 1 to 2 times per shift and add enough oil. The temperature of the bearing parts should not exceed 50 degrees centigrade.
(2) before feeding, the cylinder and the molding die must have a certain heating constant temperature time, and it is not allowed to be put into production under the condition of low temperature.
(3) the screw must be started at low speed, and the screw speed can be increased only after a period of operation at low speed.
(4), the screw in the barrel of the air transfer time is not allowed to exceed 2 ~ 3min, in order to avoid the screw and barrel rolling.
(5), the current changes of extruder work should always observe the main motor, the motor that work for a long time in overload conditions (allow overloading), should immediately stop, find the cause of the malfunction, troubleshooting and then continue production.
(6) after the first heating of the cylinder, the cylinder and the base are connected to a fixed screw.
(7) before installing the screw and die, it is necessary to clean the contact surfaces of the parts, and the fastening bolts should be coated with a layer of molybdenum disulfide or silicone oil, so as to facilitate the disassembly of the parts at high temperature. Disassembly and assembly of the parts are not allowed to use heavy hammer to knock the various parts of the face, if necessary, to pad hardwood, hand percussion hardwood removal parts.
(8), cleaning barrel screw, and the mold materials, can only use bamboo or copper knife scraping sticking material, are not allowed to use steel knife sticking material, but are not allowed to remove the residual material through the screw with fire method.
(9), regular maintenance in continuous operation of 2500-5000h extruder machine after stopping, wear machine needs disintegration inspection measurement and identification of main components, the replacement has reached the prescribed limit of wear parts, repair damaged parts.
(10), the conditions permit, it is best to designate a person responsible for equipment maintenance. And the detailed records of each maintenance and repair are included in the plant equipment management files.
