• oil-lubricated rotary vane vacuum pump
Oil-lubricated rotary vane vacuum pump is widely used in the cleaning system. Experience has shown that this type of pump is well suited for such applications, it also became the drying process of cleaning system standard pump. Rotary vane vacuum pumps are long life and a high level of vacuum powerful vacuum generator. However, when it comes to having a high probability of occurrence of the steam cleaning process, rotary vane vacuum pumps is not always possible to prevent the occurrence of steam in the process of removing the vacuum pump suction condensed. At the same time, the vacuum pump condensate oil emulsion. This may lead to insufficient lubrication of rolling bearings and rotating blades, resulting in other parts of the pump wear, suction performance and the expected degree of vacuum may be affected. These effects may be more frequent destruction of the vacuum pump oil and filter to cause a rise in the overall maintenance and operating costs.
By the Dr. K. Busch GmbH manufactured dry rotary screw vacuum pumps and there is a long history of success in a wide range of vacuum process technology. Vacuum pump has been successfully meet all kinds of different specific application requirements, beginning in 2005, successfully used in industrial cleaning and drying technology, and as a new standard in the field of vacuum technology dissemination.
Busch COBRA screw vacuum pumps do not need oil as a working fluid. During the drying process, it has the advantage that condensation in the compression process is not in contact with the oil formation, and thus ruled out the possibility of an oil-lubricated rotary vane vacuum pump related issues arise.
In COBRA screw vacuum pumps, twin screw rotor in the opposite direction of rotation of the cylinder, or the cylinder wall is not in contact with each other. Similarly, sealed using a non-contact manner, thus no wear occurs. If the steam condenses during compression COBRA screw vacuum pump, the air flow will still be pushed to the exhaust side of the compression chamber ruled out. Therefore, the liquid volume of a few liters per hour, can without any problem through the pump body. Outfall design in such a way, even when the pump is at a standstill, it can easily discharge condensate liquid.
Unlike rotary vane vacuum pumps, screw pumps are water-cooled. Cooling principle designed to ensure a uniform and stable absolute temperature through the entire pump. The amount of coolant can be adjusted by the average value of the thermostat, allowing the process pump has an ideal temperature control, and to avoid unnecessary waste of water resources. Further, a pump having a sealed cooling system (heat exchangers) can also be installed locally on the device not available coolant.
