Sichuan Changzheng Machine Tool Group Co., Ltd. and Dongfang Steam Turbine Works have jointly developed and developed, and have the international advanced level. The XKH2000 five-axis linkage blade processing center pioneered in China has recently been successfully developed. On April 11th, an appraisal committee composed of 18 members of the Dongfang Steam Turbine Plant and a team of engineers and technicians came to Changzheng Company to identify the product.
XKH2000 five-axis blade machining center is a new type of blade processing machine. It adopts advanced and reasonable technology: the rotary table has the characteristics of high torque, fast response, high precision and good wear resistance. The spindle has a wide range of gears and double gears are selected. The transmission mode of the anti-backlash, the distribution of the transmission components is reasonable, the performance is superior, the positioning accuracy and repeatability of the machine tool are improved; the tool change is accurate and reliable, and the defects of the tool and the blade are damaged by the sudden power failure of the main shaft casing; the machine tool is ensured. With high precision and high reliability, it can meet the blade processing with length of 2000mm and diameter of less than 500mm. The dynamic column layout makes the machine tool have good approach performance and the machine tool is pleasant to operate.
The successful development of this machine tool is difficult because it is the first in China and the technical difficulty is quite large. In the process of development, the long march and the leaders of Dongqi and the engineers and technicians involved in the development carried forward the spirit of the Long March Dongqi, overcoming many difficulties, and succeeded in trial production for two years. After a period of operation and analysis of the components, it was determined that the machine had been Meet design and manufacturing requirements. The machine tool is mainly used for gas turbine power equipment, and similar machine tools are imported domestically.
Experts believe that through the strong combination of Changzheng Company and Dongfang Steam Turbine Works, the advantages and complementarities of the XKH2000 five-axis linkage blade machining center developed by the XKH2000 five-axis linkage blade machining center have reached the design requirements; From the perspective of the quality of the blade test piece, the axes of the machine tool are well matched and the dynamic performance is good. The development of the machine tool effectively solves the processing of long blades, and will provide a new blade machining machine for Dongqi, increasing the processing capacity of Dongqi blades. At the same time, the successful development of the machine tool has improved the development capability and manufacturing level of the Long March machine tool and broadened the market. It laid the foundation for Changzheng Company to actively respond to the financial crisis and promote the sustainable and sustainable development of enterprises.

Flow Calibration Column

Flow calibration column is widely used in flow calibration of metering pump and dosing device, which can accurately calibrate the output flow of metering pump. Flow calibration column is also called flow calibration tube, calibration column, calibration tube

Transparent tube material: plexiglass, transparent PVC,
Connector material: PVC, stainless steel,
Connection mode: internal thread, external thread and flange.

1. Overview
Flow calibration column is widely used in flow calibration of metering pump and dosing device, which can accurately calibrate the output flow of metering pump. Flow calibration column, also known as flow calibration tube, calibration column, calibration tube, the main material: plexiglass, transparent PVC and stainless steel; connection methods are internal thread, external thread, flange.

2. Selection of flow calibration column
The selection of flow calibration column is determined according to the requirements of pump flow and calibration time. For example, if the flow rate of the pump is 60L / h, and the customer needs to calibrate the flow rate of 0.5-1min, then the calculated flow rate per minute should be 60L â–³ 60 = 1L, then a calibration column with a volume of 1l can be selected.

3. Usage of flow calibration column
When using, the calibration column is filled with medium, and the liquid level of the medium is consistent with the maximum scale of the calibration column. According to the volume of the pump, open the pump volume, and then check whether the pump is calibrated according to the volume of the pump.
