The setting characteristics and structural characteristics of the spiral scale

　　spiral scaleThe setting characteristics and structural characteristics of

Set features

1) Special type for the measurement and control of powdered raw materials.

2) The feeding spiral has a stable flow structure, and the feed powder sinks evenly on the overall feed inlet cross-section, making it difficult to arch and flush the material.

3) Cycloidal pinwheel reducer ensures long-term stable operation.

4) The steady-flow spiral adopts a variable pitch structure and an inlet and outlet overflow method, which effectively solves the problem of punching raw materials.

5) The measuring spiral scale adopts a high-precision sensor (tensile strength), which can instantly achieve high-precision structure, which effectively solves the error caused by the high-precision of the lever and greatly improves the measurement accuracy.

6) Use a fast data collection model, with an effective resolution of one million; a collection rate of 50 times\/second; the annual drift is less than 50 PPM; the temperature drift is less than 50 PPM.

7) Airtight structure to reduce dust emission.

Structural features

(a) The scale body of the spiral scale is made of pipe fittings, and is made of polyester cloth and plastic to ensure airtightness. The airtightness is good, and dust does not float around during the transportation of raw materials, and there is no air pollution.

(b) The high-precision bridge has a simple structure, and the levers are made of rectangular steel tubes, which have good bending stiffness and no deformation.

(c) The structure adopts friction-free trunnion-type fulcrum, which is earthquake-resistant, dirt-resistant and corrosion-resistant.

(d) Using high-precision pull-type standard sensors, pull-type installation is convenient, fast, and stable, and can effectively reduce nonlinear errors.

(e) The weighing display instrument has the functions of automatic calibration, zero calibration, distance adjustment, fault diagnosis, etc., and has optional automatic zero-point tracking.

(f) Promote the equipment to use a direct-connected cycloidal pinwheel reducer, which has low noise and no vibration.

(g) The operation process and maintenance are simple, and the calibration and correction methods are simple and easy to implement.
