The Shandong chemical industry has overcome the influence of various unfavorable factors and the economic operation has remained generally stable. From January to April, Shandong's chemical industry accumulatively completed the current gross industrial output value (excluding crude oil exploitation, the same below) of 648.5 billion yuan, realized main business income of 640 billion yuan, and completed export delivery value of 32.3 billion yuan, an increase of 19.8% over the same period of last year. 19.3% and 19.4%. Among the 28 products monitored by the Shandong Petrochemical Industry Association, the output increased by 22 types, which accounted for 78.6%. Among them, pesticides, synthetic fiber monomers, fertilizers, pure benzene, pyrite, and sulfuric acid output grew faster. Affected by the sharp decline in oil refining and efficiency of the two alkali industries, the Shandong Chemical Industry achieved a profit of 30 billion yuan in the first four months, a year-on-year decrease of 1.2%, but the rate of decline was 5.4 percentage points lower than in the first quarter.

Inverted vertical wire drawing machine

Host: The take-up reel installed on the top of the rack is rotated by the AC motor through the gear reducer, and the AC motor speed is controlled by the AC drive to achieve stepless speed regulation.

Take-up trolley: The take-up trolley is equipped with a drop device, and the bottom rails allow the trolley to enter and exit.

Electric control system: It is composed of AC frequency converter, contactor and operation panel. This system uses AC frequency converters to control asynchronous motors. The inverter changes the frequency of the input power of the three-phase AC motor, which enables the AC motor to realize stepless speed regulation. Its speed regulation features are good, the scope is wide, the protection function is all, the volume is small, the weight is light, the structure is simple, and the installation and maintenance are convenient.

Pneumatic system: consists of cylinders, solenoid valves, gas source triplets, etc. This system is controlled by the solenoid valve to control the wire on the reel and press it smoothly.
