Technical Reform of Water Ring Vacuum Pump

Technical Exploration and Improvement of Water Ring Vacuum Pump in Use
1. Establishment of renovation plan
Considering the cost of the retrofit, two 2YK water ring vacuum pumps were used in the retrofitted vacuum transportation system. Because the first touch of this type of equipment, the performance of 2YK water ring vacuum pump is insufficient, coupled with the long time shelf of the pump, the overflow parts show rust, and because there is no specific quantitative specification for smoke and dust. In operation, the transportation power is low, forming a backlog of smoke and dust, and even forming a caking or powder fire, which brings great labor intensity. When the situation is severe, the workers show the phenomenon of exclusion. On the one hand, they adopt rehabilitation to clear the ash spiral to send the ash, so as to ensure normal production. On the one hand, actively look for reasons and solutions. Arrange relevant personnel to tackle key problems, and ultimately think that the pre-water ring vacuum pump bag filter has a higher orientation, unreasonable pipeline equipment, and pipeline diameter is too large. Combined with the actual situation of the site, the diameter and direction of the pipeline have been changed. After the transformation, the transportation function has been greatly improved.
2. Work condition after transformation
Although certain effects have been achieved by changing the diameter and direction of the pipeline, the normal pneumatic transportation is still unsatisfactory. In order to improve the site environment and reduce power consumption, it was decided to replace two energy-saving SK120 water ring vacuum pumps. After the new pumping device, it can completely satisfy the need of production. But through less than half a year's work, the new pump has the following phenomena.
​
1) The fittings are damaged. The working sound is abnormal, and the vacuum degree is also declining.
2) All the flow surfaces of the pump body are corroded and worn severely, and the front and rear side covers show holes.
3) Inlet, cylinder and bottom leakage of gas-water separator.
4) In the work of vacuum pump, the V-belt has large amplitude and severe wear and tear, and announces that the harsh voice has brought many impacts and damages to the post operators.
