What causes affect the working efficiency of 2bv2071 vacuum pump?
1. Steam pressure
The low steam pressure and pressure fluctuation have great influence on the capacity of vacuum pump, so the steam pressure should not be lower than the required working pressure. However, the structural design of the vacuum pump used has been finalized. If the steam pressure is increased too much, the pumping capacity and vacuum degree will not be increased. In addition, to ensure that the steam pressure supplied by the boiler is stable, it is better to use a boiler to provide working steam for the steam jet pump, so that the steam pressure will not fluctuate and the performance of the vacuum pump will be stable.
2. Circulating cooling water
If the cooling water supply is insufficient, the condenser will heat up, the sound of air flow will increase, the vacuum degree will drop rapidly, and even the steam will return to the suction pipe. Condensate plays an important role in multi-stage vacuum pump. Condensate can condense steam fully. The partial pressure of water vapor in the discharge pressure of vacuum pump must be higher than the corresponding full steam pressure. Therefore, the temperature of condensate water should be lower than the full temperature under the pressure to ensure the normal operation of the pump body.
The nozzle is an important part that affects the performance of vacuum pump. The existing problems are: the nozzle is installed incorrectly, installed Skewly, blocked, damaged, corroded and leaked. No matter what preventive measures are taken, the nozzle blockage is inevitable. On the one hand, when the steam pipe is installed, the residual iron chips and welding slag in the pipe will block the nozzle; on the other hand, when the vacuum pump system is stopped, the steam pipe is easy to rust, and the rust spots fall down and block the nozzle when using.
4. Usage environment
The environmental impact mainly refers to the pollution of the system caused by the extracted gas. In the process of liquid steel disposal, a lot of gas will be released from the molten steel. At the same time, some small particles such as oxide scale will be sucked into the vacuum pump. These small particles will accumulate and adhere to the pump body, which reduces the flow conductivity of the suction pipe, prolongs the pumping time and reduces the pumping function of the pump.
