Techniques for Ensuring the Levelness of Slurry Pump Installation

---

• TIME : 2025-12-22

The slurry pump is subjected to high wear and vibration during operation. If installed unevenly, it can cause shaft eccentricity, seal leakage, bearing overheating, and even impeller damage. Therefore, ensuring its levelness is a key prerequisite for ensuring long-term stable operation.

Installation and leveling techniques

The following are the key steps and technical points to ensure the horizontal installation of slurry pumps:

Basic Preparation

Ensure that the concrete foundation is strong and flat, and reserve anchor bolt holes.

Use a level to preliminarily level the position of the shim, laying the foundation for subsequent fine adjustments.

Base installation and rough adjustment

Place the common base of the pump and motor on the inclined pad iron.

Adjust the height using a combination of flat and diagonal shims to make the base roughly horizontal.

Accurate positioning and secondary grouting

Adopting the "secondary grouting method": temporarily fix the base and align the coupling; After the alignment is completed, pour concrete into the anchor bolt holes; Finally, complete the overall grouting.

This method can avoid the problem of inability to adjust the position caused by one-time grouting.

Levelness detection method

Place the level gauge on the flange surface or machining plane of the pump outlet for measurement.

The horizontal tolerance standard is 0.1/1000, which means that the height difference per meter of length should not exceed 0.1 millimeters.

suggestion

After completing the pipeline connection, it is necessary to recheck the alignment of the pump and motor, as the additional force on the pipeline may damage the original alignment state. In addition, after operating under high temperature conditions for a period of time, a thermal alignment review should be conducted to compensate for the impact of thermal expansion.
