Challenges in Screw Pump Precision Manufacturing

The performance of a screw pump is significantly influenced by the manufacturing precision of its key components, particularly the dimensions and gap of the screw. Below are the primary challenges encountered in the manufacturing process of screw pumps:

1.Dimension Requirements

①The outer diameter, pitch, lead, and other dimensions of the screw must be controlled within micrometer-level tolerance (usually ±0.01 to ±0.05mm).

②For double-screw or triple-screw pumps, the meshing gap between screws must be uniform (typically between 0.05 and 0.15mm). A large gap can lead to internal leakage, while a small gap may result in jamming or wear.

2.Consequences of Poor Precision

①Fluid Leakage: A large gap or deviation can cause the fluid to flow back from the high-pressure area to the low-pressure area, then reducing volumetric efficiency.

②Efficiency Decrease: Increased internal leakage and friction lead to higher energy consumption.

③Vibration and Noise: Uneven meshing or axis deviation can cause mechanical vibrations and noise.

④Wear Intensify: Surface roughness or insufficient hardness can shorten the screw’s lifespan, especially when transporting fluid containing particles.

⑤Jamming Risk: A small gap or uncompensated thermal expansion can lead to screw lock due to temperature changes.

Measureing? Challenges

• When measuring the wall thickness of small-sized sheet metal square tubing, traditional measuring tools often fail to meet the required precision, and human errors easily occur.
• Traditional methods only provide static data and are unable to monitor the changes of the fitting sizes in real-time or detect quality issues during the production process.

Recommended Solution

1） Measurement Principle

When measuring square tubing, the operator needs to hold the portable arm and touch the probe on the surface of the measured target. By rotating and moving the elbow, the arm is able to collect coordinate data from different positions on the tubing. Then, the data will be transmitted to the control system and processed and analyzed by the software. Finally we get the required dimensions, shapes, and positions of the tubing.

2） Measurement Steps

• Establish the Coordinate System

① Compare the workpiece with the drawings. Analyze the drawing requirements and relations between each dimension, and identify the features on the workpiece. Use the measuring arm to detect the relevant feature elements.

② Import the CAD model. After importing the CAD model, the PMT engineer will delete unnecessary components (such as cylinders, connecting blocks, valve islands, brackets, screws, etc.) according to the requirements of the CAD model, and retain the modules that need to be inspected.

③ Establish the coordinate system (usually using methods such as the center point of the plane axis, iteration, etc.). Align the measured data with the nominal data to establish the positional relationship between the measuring arm and the workpiece. This will facilitate the next steps.

• Data Acquisition

Contact measurement with the portable measuring arm: The engineer will collect data by touching the surface of the workpiece with the ball probe of the arm and use the least squares method to best-fit the measured data parameters.

• Data Analysis

Based on the technical requirements, we can analyze the position of holes and surfaces. In the measurement system, the shape deviations, position and other parameters of the measured object can be evaluated, and the key dimensions can be marked.

• Report Generation

Generate a report based on the measurement results. The report should include basic information about the measured object, parameters, results, error analysis, and other relevant content.

• Feedback of Results

Send the measurement results to relevant departments so the company can facilitate subsequent production, processing, and quality control activities.

• Batch Inspection

Since sheet metal components are often mass-produced, it is common to conduct random sampling or batch inspection of the same product. In such cases, the creation of new workpiece command in the software can be used for repeated inspections, with no need for data editing or processing, greatly improving measurement efficiency.

Advantages of the Portable Measuring Arm in Pipe Fitting Inspection

① High Precision

The PMT portable arm employs advanced angle encoder technology, enabling high-precision measurements that meet the requirements of most industrial production and quality inspection processes.

② High Efficiency

Compared to traditional methods, the PMT measuring arm is easy to install and calibrate.

③ Strong Flexibility

The PMT portable measuring arm can rotate and move flexibly, adapting to the measurement needs of square tubing of various shapes and sizes. It can also be used in complex environments.

Other Applications

In industries such as mechanical manufacturing, automotive manufacturing, and aerospace, square tubing is widely used in the production of various structural components. For large square tubing structures, such as steel structures in construction or bridge structures, the PMT measuring arm is able to perform rapid on-site inspection to ensure construction quality control.

During the research and development of square tubing, the PMT portable arm can provide precise measurements of samples to optimize the design process. It can also compare different schemes and select the optimal design for customers.

It all only took two weeks, saving about 40 percent of the time compared with traditional methods.

Molds and Production Tools Inspection

Use ALPHA Arm to do regular inspection of molds and production tools, and to analyze the wear condition so repairs or replacement could be made. For example, the customer used the PMT Alpha arm on their auto parts production line to inspect the mold on a regular basis. They detected and fixed a slight wear problem in time, helping prevent production delays and cost increases caused by mold damage.

CAD Model Comparison

Using ALPHA Arm to measure 3D coordinates will help ensure the accuracy of auto parts. We can see deviations between the actual workpiece and the CAD model by comparing the measured data with the nominal data. For example, in a process of quality control of key components, the operator used the ALPHA arm to detect dimensional deviations in a batch of components, and feedback was immediately sent to the production department. It effectively helped prevent the customer from producing batches of substandard products.

Tool Alignment

We can make adjustments to the assembly position according to the obtained accurate data of the auto parts so as to make sure the accuracy and quality of the whole process. For example, on the assembly line of a high-end model, the application of the PMT ALPHA arm has improved the assembly accuracy by 20 percent, significantly enhancing the quality of the vehicle and customer satisfaction.
