Repair of the barrel
Repair of the barrel The inner surface hardness of the barrel is higher than that of the screw, and its damage comes later than that of the screw. The scrap of the barrel is the increase of the inner diameter due to time wear. Its repair method is as follows: 1, due to wear to […]
Conical twin screw extruder and wear failure repair methods extruder wear failure after depending on the screw and barrel wear degree and repair symptoms can adopt the following methods
Conical twin screw extruder and wear failure repair methods extruder wear failure after depending on the screw and barrel wear degree and repair symptoms can adopt the following methods: by measuring the screw and barrel of wear in 0.30 Within the mm range, the screw and barrel can be chrome-plated and then finely ground and […]
Conical twin-screw installation
Conical twin-screw installation Conical double screw to install bite together of the conical twin-screw see below. The installation of conical twin-screws and parallel twin-screws is not quite the same. Since the conical twin-screw has a taper, it can only be installed from the back of the screw barrel. First, remove the special tool for the […]
Disassembly and Assembly Process of the Screw
Disassembly and Assembly Process of the Screw (1)Open the machine head and extrude the material in the extruder. After the material is completely extruded, keep the screw idling for at least 5 minutes to prevent residual material inside the screw from affecting screw removal. (2)Remove the pressure sensor from the machine head and open the […]
Repair Methods for Screws and Barrels
1.1 Thermal Spraying Repair Thermal spraying offers surface strengthening for repairs, characterized by high-quality wear-resistant coatings, low cost, high efficiency, and wide applicability. Its basic process involves: melting spraying materials (metals, ceramics, plastics, etc.) into a liquid or molten state, refining them into particles ranging from tens to hundreds of microns, and spraying these particles […]
Main causes and solutions of screw extruder wear
Main cause of wear of the screw extruder The normal wear of the screw and cylinder of the screw extruder mainly occurs in the feeding area and the metering area. The main wear reason is caused by the dry friction between the slice particles and the metal surface, and the wear is reduced. Screw and […]
How to install and adjust the screw extruderInstallation of the barrel
How to install and adjust the screw extruderInstallation of the barrel When the barrel deviation, the screw may be difficult to load, barely loaded The screw will be squeezing noise, or damage the screw shaft And shaft sleeve, or scraping screw and barrel, causing disallowed damage. The way to adjust the deflection position of the […]
The installation method of the conical twin-screw of the plastic extruder
Here is the general installation method for the conical twin screws of a plastic extruder: 1. Preparation Work Clean relevant components of the extruder, including the barrel, screws, coupling, etc., to ensure there is no debris or dirt. Check whether the new screws meet the specifications and whether there is any damage or deformation. Prepare […]
