How to debug the electric concrete batching plant

1 Overview
In all electric concrete batching plant equipment installation, wiring and electrical control system and after the completion of the unit owners and suppliers of the person concerned after examination recognized by the mechanical and electrical and other relevant personnel to debug. Trial is to confirm the installation was successful, and the electronic control system wiring is correct, performance, and economic and technical indicators electromechanical equipment meets the requirements of the contract.
2. Preparation before test
2.1 All mechanical equipment should be related to the specification requirements for inspection and lubrication filling oil gear, rotated by hand if necessary, to ensure safety.
2.2 confirm that all electrical connections meet the requirements of the drawings, the wiring is correct, grounded. Confirmed that the supply voltage to meet the requirements.
2.3 Verify that the system air pressure is greater than 0.6Mpa, compressed air is dry and clean, and open the tank drain valve deflated sewage. 0.7Mpa air line to seal the pressure test, check all joints for leaks and promptly eliminated. After the air line pressure test, blowing pipe, oil mist filling 10 oil.
2.4 confirmation mixers, screw machine, tape machines, combined aggregate hoppers, aggregate storage, powder silos, water tanks, additives, etc. inside the box clean and free of debris.
3. No-load test
3.1 on the power switch and power button on the console and check the power supply is normal, check the emergency stop button is effective and reliable early warning signal, ready to load debugging.
3.2 itemized test each device to start and stop the motor (with scene buttons and console buttons to start and stop), check the motor rotation direction is correct; especially the twin-shaft mixer, to pay attention to its two electric motors turn, should be separately start confirming its motor after turning right before the merge starts. No-load running for 15 minutes, check the operating conditions and the degree of heat bearing.
3.3 itemized solenoid valves manual test button and the console button pneumatic actuator member (including arc gate, butterfly valves, ball valves, etc.) action is correct. Action should be no obstruction, creeping phenomenon. Pneumatic adjustment element group lubricator drip flow to ensure smooth operation of pneumatic components.
3.4 Check and adjust the limit switch, proximity switch operation correctness.
3.5 Adjustment nine hopper level, and to ensure that the door is closed tight arc, proximity switch on the cylinder. Said admixture to adjust the level of the bucket, to ensure verticality sensors. Static school scale: the computer is set in the state school scales with weights by one school scale and recorded, calculate static accuracy. Static accuracy of ± 0.1%, does not exceed ± 0.2%.
3.6 mixer idling test: no confirmation within twin-shaft concrete mixer miscellaneous foreign body after the first start of concentrated oil pump mixer bearing grease, and then start the mixer motor to run for 30 minutes and the normal operation, the stirring blade cylinder wall clearance is adjusted to <3 mm. (See mixers Instructions)
3.7 Check screw conveyor without confirmation miscellaneous foreign objects, one by one start screw conveyor, running 15 minutes without exception.
3.8 Start the tape machine, when feeder starts operation, the tape may not deviation, if any deviation adjustable rear tension bolts and self-aligning roller. It runs 15 minutes without exception.
3.9 No-load linkage test: computer manual and automatic mixing plant load linkage test systems, test equipment startup sequence is correct, the equipment and body movements are normal. Adjustment is completed, all of the mechanical linkage should be eight hours running-load test.
4. Overload test
In the no-load commissioning confirmed after passing system forms the basis of concrete on the material can be overloaded on test and production test. Overload test and production test can be combined.
5. Microcomputer function tests
In accordance with the computer operation manual for the upper and lower computer features one by one test, check the check print a single print or modify a single format.
6. The concrete test specimen
Concrete samples ultimate performance is affected by many factors, only as a reference test sample mobile mini concrete batching plant trials.
7. The test organization and test report
Test organizational unit by the owner, design units and technical support, the parties concerned in close cooperation. After passing the test performance, the parties sign the test report. professional concrete batching plant allowed into official use.

2016 concrete batching plants price action and Price Predictions

Currently, due to the transformation of economic growth mode, hard, raw materials, financing and other costs continue to rise, to the enterprise caused enormous operational difficulties. On the other hand, China's economy after years of rapid development, has become the same type of equipment, excess capacity, deterioration of the market environment and other issues, China's mobile mixing station enterprises are concentrated in the low-end market, killing, and high-end equipment almost nobody cares. What measures should be taken to solve these problems in the future to achieve a breakthrough it?
Because a lot of the development of mineral resources, the amount of resources available to continue to decline, resulting in taste dwindling ore mining, smelting and other follow-up processing for beneficiation product quality requirements are increasing. At the same time, the human environmental awareness been intensified. These realities of mobile mixing station raised higher and higher requirements to promote mobile mixing station to keep the bigger, better direction and energy efficient development.
First mobile mixing station should transition the domestic market to the international market. Information age, mobile mixing aspects of global development should stand for, the use of global resources and platform to develop suitable equipment; the same time, in terms of sales but also a strategic vision of globalization, the market will be widened to a broader field.
Second, the manufacturing strategy mobile concrete batching station transition from a fixed mode to a more flexible way. With a variety of new industries emerge, mobile concrete mixing station must be able to meet the different needs of different customers. So manufacturers design mobile mixing station should be more diverse and flexible, improve the scope of application of the device.
Finally, the mobile concrete mixing plant should be transformed into a single manufacturing technology and other technology integration. Focus on the development of mobile mixing station in the integration of electronic controls, control software and other technology to effectively improve the production efficiency of the equipment.
Mobile concrete batching plant and development of the beneficiation process is synchronous, the process is dominant, the device is the foundation. The birth of a new type of mobile mixing station, beneficiation process often brings change. Technical level of equipment is a prerequisite not only the level of technology, but also directly affect the smooth flow of production processes and applications.
Scientific and technological progress, and mutual penetration of mutual integration between industries among scientific fields, extensive application of new structure, new materials, new technologies and new processing technology after another, mechatronics and automatic control technology, a strong promotion of mobile concrete batching plants and innovation to energy-efficient direction.
