Mobile Asphalt Mixing Plant is mainly composed of mixing host, dosing system, fuel system, support device and dust removal system. Among them, the mixing machine is the core part, which is responsible for mixing various raw materials evenly to produce high-quality asphalt mixture. The dosing system is responsible for adding various raw materials to the mixing machine in a certain proportion. The fuel system powers the entire device, usually using diesel or gasoline. The support unit includes four wheels and a suspension system that allows the device to travel and operate in a variety of terrain conditions. The dust removal system is responsible for collecting dust and exhaust gas generated during the production process to ensure a clean working environment and air quality.
The working process of the mobile asphalt mixing station mainly includes the following steps: First, the various raw materials are prepared and added to the mixing machine through the dosing system. Next, the mixer machine starts to work, mixing the raw materials evenly to produce the asphalt mixture. The asphalt mixture is then transported to the construction site for road paving or maintenance. In the whole process, the operation of the mobile asphalt mixing plant is simple and convenient, and it can be quickly deployed and moved, which greatly improves the construction efficiency.
Compared with the traditional fixed asphalt mixing plant, the mobile asphalt mixing plant has the following advantages: First, it has the characteristics of strong mobility and rapid deployment, and can adapt to a variety of complex terrain and construction environment. Secondly, the installation and disassembly of the mobile asphalt mixing plant is very convenient, and the transfer and installation of the equipment can be quickly completed, reducing the construction time. In addition, the operation of the mobile asphalt mixing plant is simple and easy to maintain, reducing the skill requirements of the operator and maintenance costs.
In short, the mobile asphalt mixing plant is an efficient, convenient and mobile asphalt mixture production equipment, which is suitable for all kinds of road construction and maintenance projects. It has many advantages, can provide high quality asphalt mixture for engineering, improve construction efficiency, and has a wide range of application prospects.
Characteristics and applicability of electromagnetic valve
First, the characteristics of the solenoid valve 1 gas, liquid or mixed state were selected different types of solenoid valves, such as ZQDF for air, ZQDF-Y for liquid, ZQDF-2 (or -3) for steam, or easily cause Misoperation. ZDF series of multi-function solenoid valve is available in the gas. Liquid. The best time to state the media state, the installation users do not have to adjust. 2 different temperature medium products, or the coil will burn, aging seals, seriously affect the life of the life. 3 Medium viscosity, usually below 50cSt. If more than this value, diameter greater than 15mm with ZDF series of multi-function solenoid valve for special order. Path less than 15mm set high viscosity solenoid valve. 4 medium cleanliness is not high should be equipped with a recoil filter valve in front of the solenoid valve, low pressure fashion can choose direct acting diaphragm solenoid valve such as CD-P. 5 If the medium is directional flow, and do not allow reverse flow ZDF-N and ZQDF-N single flow in both directions, please make special requirements. 6 medium temperature should be selected within the allowable range of the solenoid valve. Pipeline parameters 1 According to the media flow requirements and pipeline connection options valve port and model. For example, the small diameter selection CA5 and Z3F for one pipe to two pipes, ZDF-Z1 / 2 for medium or large diameters. Another example is the control of the convergence of two pipelines, please choose ZDF-Z2 / 1. 2 According to the flow rate and the valve Kv value selected nominal diameter, but also optional with the pipe diameter. Please note that some manufacturers are not marked with Kv value, often the size of the valve hole is smaller than the interface diameter, must not be greedy price low and misleading. 3 working pressure minimum working pressure differential above 0.04Mpa is optional indirect pilot; minimum working pressure close to or less than zero must be used direct or step-by-step direct type. Three. Environmental conditions 1 The maximum and minimum temperature of the environment should be selected within the allowable range, if there is any special order made for tolerance. 2 environment, high relative humidity and rain drops and other occasions, the election should be waterproof solenoid valve. 3 environment often vibration, bump and impact occasions such as special varieties should be selected, such as marine electromagnetic valve. 4 In a corrosive or explosive environment should give priority to the use of corrosion-resistant selection according to safety requirements. 5 If the environmental space is limited, please use the multi-function solenoid valve, because it eliminates the need for bypass and three manual valves and easy on-line maintenance. Four. Power conditions 1 According to the type of power supply, were selected AC and DC solenoid valve. In general AC power access convenience. 2 voltage specifications exhausted preferred AC220V.DC24V. 3 power supply voltage fluctuations are usually used + 10% AC-10%, DC allows ±% 10 or so, if over-tolerance, voltage regulation measures must be taken or make special order requirements. 4 should be based on the power capacity of the rated current and power consumption. Should pay attention to AC starting VA value is higher, in the lack of capacity should be preferred indirect induction solenoid valve. V. Control accuracy 1 ordinary solenoid valve only open and close two positions, high precision control parameters and parameters require stable multi-position solenoid valve; Z3CF three normally open solenoid valve, with micro-Kai, fully open and closed three Kinds of flow; ZDF-Z1 / 1 combination of multi-function solenoid valve with full open, big open, small open, full open four flow. 2 Action time: refers to the electrical signal is turned on or off to the completion of the main valve action time, only the company patented product multi-function solenoid valve can be opened and closed separately adjusted not only to meet the control accuracy requirements, but also to prevent water hammer damage.
