Requirement Confirmation: Generate a requirement analysis report and confirm the details with the customer to ensure that the design direction is consistent with the customer's expectations.

Technical Program Design

Parameter design: According to the flow rate, head and other technical parameters, design a slurry pump program to meet the requirements.

Software simulation: Use fluid analysis software to simulate the operation of the pump, optimize the impeller design, flow channel structure, in order to improve the efficiency and durability of the pump.

Material Selection: Determine the material of pump body, impeller and other wet-end parts, such as high chromium alloy, wear-resistant rubber, etc., to meet the wear and corrosion resistance needs of different working conditions.

Mold design and casting

Mould Design

According to the design scheme, make the molds of pump body, impeller, throatbush and other key parts.

Precision Casting

Adopt precision casting process to ensure accurate size of parts, uniform material and avoid defects and internal stress.

Quality Inspection

Strict inspection of casting parts, including size inspection, hardness inspection, etc., to ensure that the castings meet the design requirements.

MACHINING

Rough Machining

Rough machining:

Rough machining of castings or forgings to remove excess material and reserve sufficient margin for subsequent finishing.Rough machining usually includes turning, milling, drilling, etc. The main purpose is to quickly remove material and form a preliminary shape.

Dimensional Inspection:

After rough machining, the critical dimensions of the workpiece are inspected to ensure that the machining allowance reserved is sufficient to avoid subsequent finishing machining failing to meet the tolerance requirements.

Finishing

CNC Machining

Using CNC machines for finishing, including finish turning, finish milling, and finish grinding.CNC machining can realize high precision and high consistency.

Key Component Machining

For impeller, pump casing, shaft sleeve and other important components, special finishing is required to ensure that their shape accuracy and surface finish meet the requirements to enhance the pump's operating efficiency and life.

Tolerance Control

In the process of finishing machining, the dimensional tolerance is strictly controlled, especially for impeller, bearing housing, pump cover and other parts to ensure that the parts can operate normally after assembly and avoid vibration and noise.

Surface Treatment

Polishing treatment:

Polishing treatment for key parts such as impeller, pump body, etc., in order to improve the finish of the surface through which fluid passes and reduce friction and energy loss.

Surface hardening treatment:

According to the wear of the parts, the wear-prone parts (such as bushings, impeller edges) are subjected to surface hardening treatment by quenching or spraying to improve the abrasion resistance.

Anti-corrosion treatment:

For parts that need to be corrosion-resistant, surface coating treatment or electroplating treatment can be carried out to enhance the corrosion resistance of the material and prolong the service life of the equipment.

Accuracy Inspection

Dimensional Inspection:

Using precision measuring tools such as vernier calipers, micrometers, and coordinate measuring machines, the critical dimensions of parts are inspected to ensure that design tolerances are met.

Shape and Position Tolerance Inspection:

Inspection of shape and position tolerances (e.g. parallelism, perpendicularity, coaxiality, etc.) to ensure that the assembly accuracy of each part meets the design requirements.

Surface Roughness Inspection:

Use roughness meters to inspect the finish of critical surfaces to ensure that hydrodynamic requirements are met and to reduce fluid resistance and wear.

Component Assembly and Test Run

Pre-assembly:

Pre-assemble each processed component, check whether there is any mismatch or interference, and test the fit between components.

Debugging and Correction:

According to the result of pre-assembly and fitting, the slight deviation found in the process of assembly will be corrected.If necessary, slight secondary processing of the parts is carried out to ensure an accurate fit.

Cleaning and Maintenance after Processing

Cleaning and Processing

The parts after processing need to be cleaned to remove the oil, dust, etc. generated during the processing process so as not to contaminate the subsequent assembly and operation.

Protective Treatment

Rust prevention treatment (e.g. spraying anti-rust oil) is carried out on the parts after processing is completed, and protective cover or protective film is added to the key parts to prevent moisture or corrosion during storage or transportation.

Quality Re-inspection and Warehousing

Final Inspection

After all the processing steps are completed, a comprehensive re-inspection of each part is carried out to ensure that all the parameters such as size, precision and finish meet the requirements.

Marking and Warehousing

Mark the qualified parts and make warehousing records, ready to enter the next assembly process.

General assembly of equipment

Being manufactured at the highest standards, our pumps can guarantee longer service life, higher performance, easier operation and maintenance.

Component Inspection before Assembly

Appearance Inspection: Conduct appearance inspection of all components to ensure that there are no defects such as knocks, scratches, sand holes, etc.Check whether the pump body, impeller, shaft, bearings, seals, etc. are intact.
Model checking: Check the model and specification of each component to ensure that they are exactly the same as the customized requirements to avoid misassembly.
Cleaning treatment: Use professional cleaning equipment and cleaning agents to thoroughly clean all parts and remove oil, dust and residue on the surface to ensure the accuracy and solidity of the parts during assembly.

Shaft Assembly

Bearing Installation: Install the bearings according to the assembly standard to ensure the fit with the shaft and avoid loosening or over tightening.
Radial runout and axial runout detection: After the shaft assembly is completed, use a percentage meter to measure the radial runout and axial runout of the shaft to ensure that they are within the allowable range.For those out of range, require reassembly or adjustment.

Impeller Assembly

Impeller Concentricity Inspection: When installing the impeller, make sure it is concentric with the pump shaft to reduce the vibration caused by eccentricity.
Dynamic balance test: The impeller is tested for dynamic balance by dynamic balance tester to ensure that the impeller rotates smoothly at high speed and avoid unnecessary wear.

Seal Assembly

Seal Type Confirmation: According to the design requirements of the pump, install appropriate seals (e.g. packing seals, mechanical seals, impeller) to ensure the sealing effect.
Leakage test: After seal assembly, conduct preliminary leakage test to confirm the tightness of sealing parts.

General Assembly of Pump Body

Assembly of pump body and pump cover: Fix the pump body and pump cover in place to ensure that they fit tightly without loosening or misalignment.
Appearance Inspection: After assembly is complete, check the appearance of the pump to ensure that all parts have been installed in place, with no omissions, errors or duplicate installations.

Quality Inspection and Measurement

Gauge Inspection: Use calipers, percent gauges, plug gauges and other gauges to test the assembly dimensions of each component to ensure that each component meets the design dimensions and fit requirements.
Record Feedback: For assemblies that do not meet the quality requirements, the inspectors will record in detail and give timely feedback to the assemblers, requiring immediate rework or adjustment until the quality standards are met.

Product technology verification

Being manufactured at the highest standards, our pumps can guarantee longer service life, higher performance, easier operation and maintenance.
