The curve of pressure, current, vibration and exhaust temperature parameters of the air compressor can be displayed and printed. The flow, pressure and temperature of the compressed air main pipe in the east and west regions can be displayed, and the total pipe flow can be accumulated. This central centralized control system reflects the advanced automation control level of the air compressor stations in the East and West, and is very popular among production units. The speed limit and the stop position are controlled by manually controlling the speed limit. In this way, the manual operation speed and the stop position are manually controlled, and the manual control also has the function of automatically determining the braking point. The maximum speed limit and acceleration and the braking slope of the manual forward running at different positions are the same as the automatic running, which can meet the requirements of the speed limit and position control of the insertion chain at different positions during manual operation.
In the past, the position control of the insertion chain was realized by a fixed line composed of electronic components. It did not have the function of automatically determining the braking point, nor could it achieve the braking speed of the middle curve 3, and the line was very complicated. It is very difficult to handle. The new mill was used to modify the control system of the continuous rolling mill. According to the above method, the position control and speed control of the insert chain were realized by software programming method, and a good control effect was obtained.
The equipment is stable in operation, and the air compressor station with sufficient air supply capacity is stable. The equipment is running stably and the gas supply is sufficient. It provides a reliable guarantee for the stable production of the steel pipe branch. For the 2001 steel pipe branch, the annual output is 727,000 tons. Steel pipes, contributing 45% of the design capacity. The gas produced by the old air compressor has a large oil content in the gas production quality plateau, and the compressed air output from the new air compressor after the transformation is zero.
Derrick crane, also known as Roof Crane, is installed on a fixed foundation. The top of its mast is fixed with the back braces (stiff legs). BQ models of derrick crane includes 10T Derrick Crane 2533A, 6T Derrick Crane DCB20-6, 10T Derrick Crane DCB24-10, 12T Derrick Crane DCB30-12, 16T Derrick Crane DCB30-16, 18T Derrick Crane DCB42-18.
