Vertical sump pump parts inspection

What does the vertical blowdown pump part check need to be done? What is the inspection procedure for vertical sump pump parts?

1. Vertical sump pump mouth ring

Vertical sump pump mouth ring role is in the impeller and the pump shell to form a narrow, tortuous channel, to increase the flow resistance of the medium to achieve the purpose of reducing media leakage. The ring is also set to protect the main parts of the sump pump is not affected by the role of wear, wear in the mouth ring, you can repair or replace the new ring to restore the normal assembly gap, so economical and easy maintenance. The integrity of the mouth ring and its radial gap with the impeller asked the gap, in the demolition of the sump pump should first check. If the mouth ring has grooves or other defects or has ruptured, or gap over the required value, should replace the new mouth ring or repair the original mouth ring repair welding.

Vertical sump pump in operation, the corresponding ring and impeller impeller circumference is caused by wear while increasing the gap exceeds the specified value, because the new ring diameter should be the impeller inlet diameter to the preparation of the impeller and the ring between the ring Radial clearance requirements. In the repair process, the gap to a small point in order to improve the working efficiency of sump pumps and extend the use of time.

Vertical sump pump ring repair welding steps are as follows:

Brush the dirt on the mouth of the vertical blowdown pump.

With the mass fraction of 5% hydrochloric acid, activated again.

Into the temperature of 90 ℃, l0% mass fraction of caustic soda in the dip, and then placed in clean water, 90 ℃.

4) repair welding alloy. Preheat the mouth ring to about 100 ℃, with the appropriate welding ring welding alloy on the original ring, with the same alloy with the original alloy pre-cast into the electrode, along the circumference of the circular or longitudinal direction of a road even welding up (not repeated Re-welding). After welding, can be machined to the required standard size.

2. Vertical sump pump impeller

Replacement of the impeller of the blowdown pump Impeller that has been used may cause some damage and should be replaced. Impeller surface cracks. Impeller surface due to corrosion, erosion or cavitation to form more holes. Due to erosion caused by impeller cover and leaves thinning, affecting the mechanical strength. The impeller of the mouth ring hub more serious partial grinding phenomenon without repair value.

The above is the vertical sump pump parts inspection steps. If you need to replace the vertical sump pump parts, moving parts Shenlong sump pump parts.
