RSP Equipment

Equipment is the key to manufacturing quality screw pumps, RSP invests a lot of money every year to introduce various types of high-end equipment, with vertical machining centers, horizontal machining centers, CNC screw milling machines, CNC boring machines, ion nitriding furnaces, optical curve grinding machines, gear measuring instruments, three- coordinate instruments and other kinds of high precision manufacturing and inspection equipment.
RSP has invested a lot of money in the design and construction of a domestic first-class screw pump testing center to test the flow, pressure, vibration and noise performance of each screw pump sold. With the use of high precision equipment, the company's product quality, production capacity and efficiency have been significantly increased.
Our intelligent screw pump comprehensive test center has been assessed by the expert group of the National Pump and Valve Quality Testing Center and has been awarded the "Certificate of Conformity for the Assessment of the Test Equipment" and the accuracy of the test equipment has reached the highest accuracy class 1.

The central hole positioned exactly in line with the screw machining process minimizes errors caused by the establishment of coordinates and is mainly used for the inspection of shaft parts such as screws. Calibration accuracy up to 1.0 µm.

Gear Measuring Instruments

The laboratory measures and tests the material, heat treatment etc. of the screw pump and its components to ensure the performance and working conditions of the product.

Specialized Physical and Chemical Laboratory

The key parts of the pump are machined by the machining center, with a pass rate of 99.9% at one time, effectively improving the stator machining accuracy.

Horizontal Machining Centers

In order to ensure that the bushing processing hole distance accuracy ±0.015/500mm, hole roundness = 0.01mm, end runout < 0.01mm, comprehensive pass rate ≥ 98.5%, RSP introduced the MA-600HB horizontal machining center from Japan, which can achieve high efficiency, high precision and high performance processing, so that the bushing processing accuracy can be further improved.

Horizontal Machining Centers

For bushing machining with an accuracy tolerance of 0.005 mm.

Vertical Machining Centers

Use grinding tools to grind the surface of the screw, with an accuracy of 0.005mm.

CNC Screw Grinding Machines

Use grinding tools to grind the surface of the screw, with an accuracy of 0.005mm.

Details of Three-coordinate Instruments

One of the largest professional testing center for screw pumps in China. 12 pipelines for testing requirements up to 800m³/h - 1000 m³/h.

Comprehensive Testing Center

The most critical part of screw processing is to carry out a secondary heat treatment to obtain strength, toughness, plasticity and other comprehensive mechanical properties. The ion nitriding furnace gives the screw a nitrogen-reinforced surface layer and results in high hardness, high wear resistance and high fatigue limits. The surface hardness of the screw after nitriding can reach HV500-800.
