Water ring vacuum pump impeller of the main damage divided -

2 bv5 water ring vacuum pump is usually used in the vacuum adsorption industry, it is made up of several parts, which is a very important part of the impeller, therefore, when the impeller damage, which means that the major problems existing in water ring vacuum pump equipment. Let us introduce the impeller damage types.

1, blade crack, usually appear in the blade root, most of them are fatigue cracks, and some of them are due to the gap between the blade and the wheel size and cause the casting crack.

2. Solution:

a burst of impeller should be replaced, in order to prevent the broken blade and lead to an accident.

,

1 of blade wear, impeller due to transport corrosive gas and liquid or liquid ring contains solid impurities, and the friction on the surface of the impeller or damage due to cavitation damage.

2. Solution:

1. If serious, should be replaced in a timely manner. If the damage is not serious, can be used to repair welding method.

2. Repair welding, the impeller can be heated to 600 ℃, then carries on the repair welding.

(3) the size of the blade after repair welding gun must use rasp leaf or lathe increases to the original size, otherwise it will affect the performance of the original. Three, leaf interrupt

1, because there are solid in the pump, such as metal, gravel, etc. The impeller rotates, due to the stress concentration of blade root, leaf rupture or stuck by solid block of solid, this is due to the small and medium-sized gas and hydraulic pressure in the cavity pump caused by fatigue damage.

2. Solution:

damage of impeller impeller should be timely replacement, find out the reasons, and take corresponding measures. If the strength is insufficient, can increase the number of blades.

for 2 bv5 water ring vacuum pump vacuum adsorption industry demand is higher, so 2 bv5 water ring vacuum pump has been widely used. In order to maintain equipment efficiency, we should be regular maintenance and maintenance, and check whether the internal parts damage on a regular basis, if timely solve.
