Vacuum pump is a kind of
equipment that will be applied in many industries, and it plays an increasingly
important role. However, in the process of use, it is inevitable that it will
have such or such problems. When facing these problems, we must be patient to
deal with them, because only in this way can it give full play to its use
advantages, as well as for water ring vacuum pump unit , let's talk about its
corresponding isolation processing. I hope this article will help you.
First of all, we should check whether the work is normal; whether there
is leakage point in the vacuum system; at the same time, check whether the
pipeline of the vacuum system and the continuous vent pipeline of the low
pressure heater are damaged, whether the vacuum breaking valve is closed
tightly, whether the sealing water is normal, and whether the steam supply
pressure of the shaft seal is normal; Check whether the steam inlet valve,
diverter valve and load relief valve of the shaft seal are normal, whether the
water seal of the shaft is normal, whether the shaft heater fan is in fault or
the negative pressure of the shaft heater is low, start the standby fan, check
whether the exhaust system of the small turbine is normal, if necessary, start
the electric pump, stop the small turbine and close the exhaust butterfly valve.
Check whether the sealing water of the condensate pump is normal and
whether the condensate pump leaks air; whether the water level of the condenser
is too high; if the vacuum of the condenser drops to - 87kpa, the standby water
ring vacuum pump unit will start automatically, otherwise it will be put into
operation manually; if the vacuum continues to drop, the load shall be reduced;
if the vacuum drops to - 84kpa, the load shall be reduced to zero; if the vacuum
drops to - 81kpa, the trip protection shall act, otherwise, the shutdown shall
be manually tripped.
