Description

Technical Field

[0001] The invention relates to the technical field of water pump impeller wear measurement, and in particular to a water pump impeller wear measurement device and a measurement method for metal mines. Background Art

[0002] The wear problem of the impeller of a metal mine water pump is a key factor affecting the normal operation and efficiency of the water pump. Especially during the long-term use of a mine water pump, the wear of the impeller will cause the water pump to have reduced efficiency, unstable operation, and even cause failures. The wear of the water pump impeller is mainly reflected in the gradual reduction of the impeller surface material, the appearance of pits, cracks and other structural damage, and in severe cases, the efficiency of the pump body will be greatly reduced. Effective measurement and analysis of impeller wear can timely detect wear problems, optimize the maintenance and repair cycle of the water pump, reduce equipment failure rate, and thus improve mine production efficiency.

[0003] The existing technology uses a tactile surface roughness meter to measure the microscopic roughness of the impeller surface. However, many water pump impeller surfaces are coated with anti-corrosion or anti-wear coatings, and it is not convenient to treat the coatings. The presence of these coatings will affect the wear measurement, especially when using contact measuring instruments or laser scanners for measurement. If the coating is uneven or falls off, it may reduce the accuracy of the measurement results.

[0020] 1. By setting a movable placement seat, the water pump impeller to be measured for wear can be placed in the remover solution to soften the coating on the surface of the water pump impeller. Then, the reciprocating brush plate can be used to remove the coating on the surface of the water pump impeller, ensuring that the bare metal surface is measured, making the measurement data more representative and avoiding the influence of coating errors;

[0021] 2. By setting up a transmission mechanism, the brush plate can be driven to move back and forth, and the angle can be adjusted under the action of the rack, and the water pump impeller on the placement seat can be driven to rotate at a uniform speed, thereby realizing multi-directional coating removal. The combination of multi-angle and reciprocating motion makes the coating removal more thorough, reducing the time and labor cost of repeated cleaning. Through uniform rotation and angle adjustment, the coating on all parts of the surface of the water pump impeller can be evenly removed, which can improve efficiency while ensuring the comprehensiveness and accuracy of the coating removal on the surface of the water pump impeller;

[0022] 3. By setting up a solvent treatment seat, while the transmission mechanism drives the brush plate to remove the coating, the used solvent can be sucked into the solvent treatment seat to remove the coating residue in the solvent, avoiding long-term contact between the solvent and the coating residue, keeping the solvent clean, reducing the need for frequent solvent replacement, and improving the operating efficiency of the system.

[0041] The invention relates to a wear measuring device and a measuring method for a metal mine water pump impeller, comprising the following steps:

[0042] S1. When it is necessary to measure the wear of the water pump impeller 4 used in the metal mine, the water pump impeller 4 is removed from the water pump and placed on the placement seat 3, and then the placement seat 3 is moved so that the water pump impeller 4 is immersed in the coating remover solution in the equipment seat 1 to soften the coating;

[0043] S2, then move the water pump impeller 4 to the coating treatment mechanism 6, and use the transmission mechanism 7 to drive the coating treatment mechanism 6 to treat the coating on the surface of the water pump impeller 4;

[0044] S3, while the transmission mechanism 7 drives the coating treatment mechanism 6, it will drive the water pump impeller 4 on the placement seat 3 to rotate at a constant speed, so as to remove the coating in all directions;

[0045] S4. Driven by the transmission mechanism 7, the coating remover solution containing the coating residue is sucked into the solvent treatment seat 8 for filtering treatment, and then the water pump impeller 4 with the coating removed is removed, and the probe of the surface roughness measuring device 2 is brought into contact with the surface of the water pump impeller 4 to measure the microscopic roughness of the surface, which is used to evaluate the surface condition after wear.

[0046] Working principle: When it is necessary to measure the wear of the water pump impeller 4 used in metal mines, the water pump impeller 4 is removed from the water pump, and then the water pump impeller 4 is fixed on the key shaft 301 on the placement seat 3, and then the motor A102 is used to drive the threaded rod 101 to rotate, so that the threaded rod 101 drives the placement seat 3 connected to the moving seat 103 to move downward, so that the water pump impeller 4 is immersed in the remover solution in the equipment seat 1 to soften the surface coating of the water pump impeller 4;

[0047] Then, the water pump impeller 4 on the placement seat 3 is driven to move to the coating treatment mechanism 6, and then the motor B702 is used to drive the connected reciprocating screw 701 to rotate, so that the reciprocating screw 701 can drive the moving frame 601 to move back and forth, so that the brush plate 604 removes the coating on the water pump impeller 4.

[0050] After the coating on the surface of the water pump impeller 4 is removed, it is moved out of the equipment base 1, and the probe of the surface roughness measuring device 2 is brought into contact with the surface of the water pump impeller 4 to measure the microscopic roughness of the surface for evaluating the surface condition after wear.
