1, Make well the electrical system ground ( or receive zero ) protection, and make well the whole machine lightning protection grounding and sensor shield grounding, from the power supply, if the power supply using the TT system, When installed the asphalt plant,the metal frame and control room's Electrical cabinet shell of asphalt plant are doing grounding protection. If the power supply using the TN-C system, when installed asphalt plant, the metal frame and control room's electrical cabinet shell of asphalt mixing plant should do grounding protection and access to zero reliable, this way not only achieve a asphalt plant conductive framework protect access to zero, but also to achieve a asphalt plant repeated electrical system neutral grounding. If the power supply with TN-S ( or TN-CS) system, when we installed asphalt batching plant, grounding and access to zero metal frame and control room's electrical cabinet of asphalt batching plants. Regardless of the kind of power supply system , do the grounding resistance of grounding point that is greater than 4Ω. In order to prevent asphalt plant lightning hazards, when installed asphalt plant, must be installed lightning rod in the highest point of asphalt plant, and all parts of asphalt plant must be in the effective lightning rod protection zone. the Lightning rod ground deflectors must be adopt a cross-section of not less than 16mm2, When installed asphalt plant must be have insulation protection, Copper skin, ground stations to be set up in other ground from asphalt plant at least 20m away where no pedestrian or facilities, and to ensure this grounding grounding resistance 30Ω or less.When installed asphalt plant, but also to do all sensors shielded wire grounded reliable, the ground can link the ground deflectors of control unit, but the ground is different from the previously mentioned protective ground point and anti- Ray grounding point, leaving this ground to protect the ground at least 5m away from the straight line, grounding resistance is not greater than 4Ω.
2, do well the commissioning work carefullyWhen asphalt plant initial assembly, commissioning work may need to spend a lot of energy and time, as may be found in debugging a lot of problems, such as wiring errors, component or control unit parameter setting is inappropriate, improper installation location component, component damage, etc. reasons, specifically what is the reason, it is necessary to correct or adjust in accordance with the drawings, the actual situation and the test results.After asphalt plant main part and electrical system installed, to do serious debugging work, starting with a single action manually controlled single motor load commission, if have problem do check the line and electrical components whether or not normal, if a single action single motor test action are normal, you can enter part of the unit controlled manually or automatically load commission, if are normal, then enter the full automatic load test. after work done, then do the whole machine with load test machine. after completed commissioning work, it can be said that the basic asphalt plant installation work has been completed, asphalt plant has already have a production capacity.3, do well done temperature regulation of control room, often cleaning electrical components and external unit dust, check electrical components frequently, and do well done the maintenance work of mechanical transmission part. The control room of asphalt plant is the electric control syltem core, if the control room temperature is too high, it will affect the electrical components and systems normal work reliably, so to adjust the control room temperature. Since the largerdust of field, which have a greater impact with relays, contactors and other electrical components work reliably, so regular cleaning dust from various parts of the electrical components. In order to make the various mechanical transmission of asphalt plant can operate normally, to timely manner lubrication of mechanical transmission part.
Asphalt concrete mixing plant is an important road construction equipment, it combines the mechanical, electrical and automation and many other technologies. Asphalt plants installation mainly includes base production, machine metal structure installation, installation and commissioning of electrical systems, asphalt heating and piping part of the installation. in the conditions of asphalt plant foundation built, the installation of mechanical metal structures can step in place, rarely make adjustments and changes in the future production. Asphalt heating and piping parts mainly for asphalt heating installation service, installation workload depends on bitumen storage and heating equipment . In production, the electric drive and control system weather or reliable is one important factor of affecting the asphalt plants normal production.
Installation and maintenance of asphalt plants electrical control system:1, familiar with the system, familiar with the principles, rational layout, make wiring connection Either asphalt plant is first installed or moved to a new site installation, The technical aspects of electrical installation and maintenance personnel should first familiar with the whole electrical system control mode and principles according to asphalt plant working process, familiar with the system distribution and some of the key control device specific role, so installation is relatively easy. by the peripheral portion to the each control unit or the external to control room concentration, and Cable arrangement should choose the right path, and requires the weak and strong signal cable distribution cable slot arrangement. The electrical system of the asphalt mixing plant includes strong electric, weak electric, AC, DC, digital signals, analog signals, to ensure these signals are effective and reliable transmission, make control unit and electrical components output the correct control signal timely, and can reliably drive the actuators, connection of electrical wiring reliability has played a significant impact. Therefore, during installation must be done at the connection of the wiring and electrical components installed reliable fastening. Asphalt plant mainly control units generally adopt IPC or PLC (programmable logic controller ), and their internal control processes are basically that after Internal circuit detects satisfy certain electrical input signal of logic relationship, output electrical signal timely that meet certain logical relationships to drive relays or other electrical units or components. these relatively sophisticated parts work is usually relatively reliable, if the operation or debugging fails, firstly check all the relevant input signal is or not input to the bit, then check the output signal of the outgoing inspection requirements are or not, whether according to the logic required output. Generally, as long as the input signal is valid and reliable to meet logic requirements, the output signal will be output in accordance with design requirements of internal procedures, unless wiring head (connection flapper ) loose or these control units with associated peripheral components and a fault line. Of course, individual special circumstances may also occur inside unit component damage or a circuit board failure.Now I supply a DAYU asphalt plant installation sample in algeria, if you interest it, you can click the link: www.asphalt-plant.cn/company-news/43-dayu-brand-asphalt-plant-succesful-installation-in-algeria.html.
