Mainly for the present, some still using manual canned / play materials / ingredients / add water, but do not want to put too much cost, wanted to improve the efficiency of enterprise users, we recommend the use of the system. DLPL quantitative control system according to customer requirements, customize different dosing system. First, the system is composed of a flow sensor: This is the basis of control, directly affect the control of the results, so the basic requirement is the higher measurement accuracy is better, there is a signal output function. Meanwhile flowmeter type more, but also for selection according to the measured medium, pipe diameter, flow range, explosion, corrosion, protection class and other parameters and requirements, select the appropriate meter. 2, DLPL control box: includes quantitative control device, the internal control lines and components, such as external control buttons and lights, standard size box of 400 * 300 * 150mm, input power (AV220V) unified control box to power other devices such as flow sensors, solenoid valves and other equipment are powered directly inside the control box; and increase access printing. 3, drying equipment: the existing conduit may be power equipment, such as pumps; may also be larger block of solenoid valves, electric valves and other equipment. Second, quantitative control process control instrument after receiving traffic signal meter in its interior complete cumulative flow, while the value of a good set of quantitative control required in internal control device, when the accumulated value of quantitative control instrument display reaches the set The quantitative control value, quantitative controller output switch signal. At this signal by using this switch is connected with the relay or contactor to control shut-off device is installed in the pipe, so as to achieve the effect of quantitative control. ? Third, the product features 1, only flowmeters, control boxes and drying equipment components, simple structure, low cost; 2, the control box of the control circuit and components are based on the meter and the equipment customers need to tailor The signal line connection is simple, the flowmeter and drying equipment powered directly from the control box inside, usually without adjustment to the scene;? 3, the control device for the whole Chinese display, easy operation, visual display; control box panel has a "start" "stop" and "reset" button, but also external button, and a "status indicator" shows, so intuitive display, simple operation, convenient, easy to learn;? 4, each value can be any quantitative control required changes, just the operation is completed within the quantitative control device, can also be set in accordance with the requirements of the usual dose groups, direct selection on the line, no need to set it again when playing material; Fourth, the main function of a, with large and small valve control, are controlled high flow and low flow, to achieve accurate quantitative control; 2, while the control of pumps and valves, has a pump delay start function off valve and the pump in advance; 3, with a flash, hold the pump interface, the occurrence of flash, hold pump off when playing material immediate protection;? 4, in the quantitative control device can view the total cumulative flow rate, time, flow meter input signal values, etc., and a number of hit material, each feeding time to play, you play material amount, date or month cumulative etc. inquiry; 5, can be equipped with a printer to print real-time capabilities, printing capabilities, including the starting and ending time to play material, playing quantity, quantity actual playing, playing material name (according to customer requirements set free); break Power remains active material before the fight. 6, the control device and the control box is completely independent research and development, so that we can make other features For customized; V. Ordering Information 1. Select the appropriate meter: Measuring media name advertised, measuring tube diameter, operating pressure and temperature, flow range or other requirements, we give you the selection; 2, indicating control requirements: such quantitative values ??for each size, the number of daily control, the value is the same for each control and other requirements; 3, select the drying equipment: as has been drying equipment please let its operating power and power, we make tailored; if necessary we can also provide drying equipment. Here we recommend drying device, select the solenoid valve or electric valve (a delay in startup or shutdown) is better, do not control the pump, while at the piping to the stagnation level difference generated by the power source for the best , so that when the control most secure, but also the best measurement accuracy. Sixth, on-site installation and piping diagram of an installation considerations. Meter installation (see instructions): At least guarantee before the meter before and after a straight pipe after 10D 5D (D is pipe diameter), and the longer the better, as far as possible in front of the pump and want to increase the regulating valve straight pipe before length away from them, near the mount point should be no strong electric, magnetic and frequency interference. Installation point pipeline must be full pipe flow when the pipe is installed vertically oriented, fluid must flow from bottom up. 2. Solenoid valve: meter should be installed in the rear, and with the meter should 10D (D is pipe diameter) over a distance, to avoid vibration and electromagnetic solenoid valves before and after the operation due to the impact of measurement accuracy of the meter, in addition to the solenoid valve mounting point should be as close exit flow is appropriate. 3. Control Box: Non-waterproof, it is recommended to install in the room; if installed outdoors or order shall require the use of waterproofing waterproof control box. Quantitative measurement principle ?? beginning when the flow control device indicating quantitative electromagnetic valve is open, fluid enters the flow sensor. When the flow sensor signal to the flow control device and start the quantitative measurement, the flow reaches the set value, quantitative Totalizer control device instructs the solenoid valve off, back to the original closed state.迪川 flow sensor and solenoid valve according to the site to select the desired flow rate and pipe press figure connected with the quantitative control instrument quantitative control instrument's display as shown, standard size box of 400 * 300 * 150mm (H * W * thick) of the pulse (current) flow sensor output calculation formula Q = N / K where? Q -------- cumulative flow (in liters) ??? N -------- traffic signal number of pulses (pulse number corresponding current (times) ??? K- ------ instrument constant (Ci / l) ?? placed within the meter constant control device, the control device according to the setting value is automatically calculated ), initiate recovery of the relay control device when the built-in relay state changes, so that the control valve is opened, the control device of the pulses from the sensor (current) signals are counted, the amount of the original reaches the set state, the control valve will close, in order to achieve Quantitative pipe flow (batch) control. ■ Technical parameters measuring medium: liquid or gas.
