What is the reason for the slow heating of the extruder oil?

The extruder oil temperature machine is a necessary and necessary good temperature control machine for the working process of the extrusion industry. Its function is to heat or cool the mold and maintain its working temperature, ensure the stability of the extrusion quality and optimize the processing time. The extruder oil temperature machine is not only small and light, but also has fast working efficiency. * * The important thing is that it is easy to operate, without too many complex instructions, low cost and low failure rate, so it is popular in the market.
What is the reason for the slow heating of the extruder oil?
In fact, users often encounter a problem in the daily use of the extruder oil heater, that is, what is the reason for the slow heating of the oil heater? The problem of slow heating speed can be solved from the following aspects:
Part of the heating tube of the extruder oil heater is damaged
Because many processes in industrial production are to first heat the equipment to a certain temperature, and then continue to maintain this temperature. Therefore, when designing temperature control equipment, the manufacturer usually controls the heating tubes in groups (for example, two or more groups). This advantage is that the heating components can be fully opened at the beginning of heating, and the set temperature can be reached in a short time, Then only open part of the heating tube to maintain the temperature. When one group of heating tubes breaks down or burns down, the heating speed is relatively slow due to the power reduction of the heating tubes. The only way to completely solve this problem is to replace the heating tubes.
Second, the heating power of the extruder oil is not matched
Another possibility that causes the slow heating of the extruder oil temperature machine is that the heating power of the equipment does not match the actual demand. For example, it is obviously inappropriate to use a mold temperature machine with a heating power of only 6 KW to control the temperature of a 1600RT injection molding machine. The way that the calf pulls the cart will certainly lead to the slow heating of the mold temperature machine. To solve this problem, only one high-power or controlled temperature equipment can be purchased and heated by multiple mold temperature machines.
Third, the efficiency of heating pipe is reduced due to improper use and maintenance
Because the extruder oil heater has been used for a long time, the pipeline silts up, affecting the flow and heating performance. For example, the water temperature machine is affected by the water quality, which causes the scale to adhere to the outer wall of the heating pipe and the inner diameter of the pipe for a long time, affecting the heating efficiency. The oil temperature machine will be coking due to the high temperature heating of the oil quality, and long-term failure to clean will lead to poor heating. Therefore, when the circulating medium is water, we should carry out corresponding water treatment for the supplier to avoid damage to the heating pipe due to the high water quality.
