Zhengzhou Longxing Company's innovative transformation equipment appears fruitful result

In recent years, Zhengzhou Longxing Company Equipment Department actively encourage everyone in the work of ground brains, more thinking, continue to find a variety of problems that exist in the production process, and carry out technological innovation, reduce equipment damage frequency, reduce maintenance time and improve equipment operation rate, saving maintenance costs, help plant to increase production to ensure product quality; for the successful completion of production tasks provided strong support. In this process, the emergence of a number of fruitful transformation project - 

     Fast track process requirements mill motor reverse conversion, motor inrush current is large, easily lead contactor burning or sticking, replace the contactor takes about twenty minutes, while also playing out of about a dozen root of billets. More serious is likely to cause motor burn. Once the motor burned, replace the motor also needs more than thirty minutes, but play out over twenty billets. So in this case, not only will cause equipment failure rate, maintenance for a long time, but also severely hampering production capacity to play. To change this situation, electrician class members through trial and improved motor control method, without affecting the original mode of operation, and give each track the installation of a spare motor control circuit, and a new installation of the converter circuit while the console mode of operation unchanged. After the transformation, if one set of control loop is a problem, can be converted directly to an alternate circuit can immediately normal production. In addition, for the three runways often burning motor, electrical switch metallurgical lifting classes given special motor, effectively improve the working conditions of the mill runway, reducing the probability of the motor burned. After the equipment improvement, down by month, up to 1-2 times the electrical cause, but also greatly reduces the maintenance time, and even online maintenance without downtime can be more effectively reduced the repair process played out billet problems, reducing the economic loss, while also reducing the amount of maintenance and repair costs. 

Bending machine shop mill coil due to end after a good inertia, unable to stop immediately, but later rolled steel bars have to wait for the good bending machine, if the motor is able to achieve reverse brake bending machine stop in time, the end plate rolled withdrew the request in a timely manner, but the result of this operation that led to the impact of the current large, likely to cause motor burn. Machine repair class members brainstorming, gives an effective rehabilitation programs: the gear positioning motor driven wheel, the installation of a 300mm diameter brake wheel, electro-hydraulic hold fast to install a new device, so that in time to stop bending performance without motor reverse braking, the motor can easily be burned to solve the problem. Transformation of the former, the motor was burned five or six times every month, every motor repair costs are needed more than 2000 RMB, and each two hours at least affect production, the impact of a multi-class production time, to the production caused great waste. After the transformation did not happen again through the motor burned fault, not only reduces the amount of maintenance and repair costs, but also improve production efficiency.

Vertical lathe machine shop pump motor used for a period of time, wear and tear on the motor shaft keyway serious, some keyway wear big, some ground into the hole oval, can not be used without re-processing; but the pump using a vertical lathe special import motor, the motor shaft is interpolated axes, out processing needs special equipment, processing costs, long time, no quality assurance; if you buy a new motor, a flat fee is more than 1000 RMB, This is a high cost. Now there are 20 sets of machine shop pump motor, plus damage to be repaired and spare as many as 30 units, for this phenomenon, machine repair and electrician after a period of research and exploration, and finally thought of a solution. To make a coupling to the motor to transform the inner shaft, inserting a long axis of the finished, one end connected to the motor, one end connected to the pump, and then processing a sheath fixed to the pump motor with a long screw, and adjust the gap, after many tests, and finally to achieve satisfactory results. Since then, even when the keyway bad, just replace the processed couplings, debugging can be used normally, both effort and provinces, but also serve to reduce costs, the effect of waste re-use, greatly improving the efficiency, effectively guarantee production carried out orderly. 

     In addition, there is a large punch bottom mold technical modification tapping machine motor, casting hydraulic shears track reconstruction, renovation bending machine console, the pressure welder transformation, etc., are to varying degrees, to solve production operational problems, reducing maintenance costs, reducing maintenance time and improve work efficiency, the company has created economic benefits. 

Continue to adhere to the transformation of innovative equipment management philosophy, and constantly find problems, play to their talents, the company is developing a stone in the direction of future efforts Zhengzhou Longxing Company Equipment Department, we will mobilize more people to participate in the initiative and equipment modification creativity, motivate employees in their own posts by reasonable improvement to create a first-class performance.
