AI Technical Summary

Problems solved by technology

Conventional water ring vacuum pumps, slide valve vacuum pumps or rotary vane vacuum pumps are usually used in vacuum extruders, but the following technical problems generally exist in actual use: 1) The use of water ring vacuum pumps has low working vacuum and exhaustion. Low efficiency and high energy consumption; 2) When using a conventional slide valve or rotary vane oil-sealed vacuum pump, although the pumping efficiency is improved, the gas pumped out by the vacuum extruder contains a large amount of water vapor, which is common Condensed water will emulsify the pump oil, which will lead to the problem of degraded pump performance; 3) The vacuum pump in the vacuum extruder works under the condition of large displacement for a long time, and the oil injection phenomenon of the conventional slide valve or rotary vane oil-sealed vacuum pump Serious, resulting in a large loss of pump oil consumption and serious environmental pollution; 4) The vacuum extruder works in an outdoor environment and usually lacks qualified industrial circulating cooling water. 5) The ambient temperature in different regions and seasons varies greatly, which will also lead to obvious changes in the performance of the vacuum pump, such as the freezing and cracking of the water cooling jacket in winter in the north; 6) The exhaust airflow of the vacuum extruder Generally, there are more solid dust and sediment particles in the vacuum pump. Once it enters the vacuum pump, it will directly cause the wear and damage of the pump. At present, the purification effect of the actual gas filtration equipment is not ideal.

[0003] Although there is a rotary vane vacuum pump used for brick vacuum extruders, it needs to be equipped with a motor cooling fan to cool the pump oil. The cooler is relatively large and not energy-saving enough.

In addition, if the air filter is not installed, the dust in the pumped gas cannot be filtered out, which will affect the cleanliness of the pump oil, and will affect the use effect and service life of the vacuum pump.
