The filter screen changer blocked by the exchanger will affect the temperature of molten material

When the screen changer blocked filter works to a certain extent, the pressure in the extruder body will increase and the material flow will not be smooth and can not continue to work. At this time, it is necessary to stop the machine and replace the blocked filter. When the blocked filter is replaced manually, the pressure will suddenly drop, and the temperature of molten material may also drop, resulting in changes in the size of the product. In order to maintain the same size of the product,

Misuse of gear pumps

The inlet of the gear pump inlet is not in the right direction. Many pilots think that this can improve the practice of lift, the original gear pump practice head = total head to lose head. When the type of gear pump is determined, the total head is certain; the loss of head mainly comes from pipeline resistance, the smaller the diameter of the pipe, the greater the obvious resistance, so the loss of head, the greater the cause of stainless steel corrosion analysis, so reducing the diameter of t

Control of screen changer

Control of screen changer Hydraulic control mesh screen changer can be equipped with two kinds of control systems, manual slide valve operating system or automatic circulation operating system (ACS). According to Kreyenborg, its K-SWE and continuous mesh screen changer with back-flushing device are usually equipped with ACS system, while D-SWEp intermittent mesh screen changer is generally equipped with manual sliding valve operating system. The ACS system consists of a program controller, a dra

The important position of screen changer in the production of recycled plastics

In the extrusion production of plastics, there may be various impurities and foreign substances in the raw materials as well as fine crystalline particles with incomplete plasticization, especially in the recycling process of recycled plastics, there are paper scraps, aluminum foil, sand, iron scraps, copper wire, wood scraps, defoamer and other impurities, the existence of these impurities without the installation of a mesh changer. Impurity filtration will result in the decline of product qual

The use of screen changer in the field of chemical fiber recovery

In the process of chemical fiber production, the change of material, equipment, process technology and product variety inevitably lead to the production of waste silk. If not used, on the one hand will form solid waste, or even white garbage; on the other hand, petroleum and other fossil resources are non-renewable, as the downstream petrochemical fiber industry urgently needs to recycle this part of waste. In the process of waste collection, storage and transportation, solid impurities will be
