2 Port Solenoid Valve For Dust Collector

Transcription

1 The VX* series will be revised shortly. 2 Port Solenoid Valve For Dust Collector Series 2 port solenoid valve for dust collector Series In this L-shaped 2 port valve, the bag filter is cleaned by high speed air jet and shock wave to materialize high speed response and control of instantaneous large flow rate. The supply port to the pressure action chamber is installed in the body and the diaphragm free from stress concentration has a long life span. The main valve made of polyacetal is free from sticking and strong against produced shock waves. Port size Cv A Controller dedicated for operation Series C The pressure action chamber capacity is reduced. High speed main valve opening & closing/min. pulse 0 ms The valve controller turns ON/OFF many valves for the dust controller. Power voltage: 100 V, 200 V, 24 V Output points: points, 10 points Two-time hitting function Two-time hitting can be set to improve the sweeping effect by the bag filter. Two-time hitting is available by turning ON the DIP SW (one-time by turning OFF). Connection of multiple circuit boards is possible Number of output points can be increased (1/20/2/30 points) by connecting boards. Wide ranging time setting ON-time (output to the valve): 0.01 to 1 sec. OFF-time (adjournment to next output): 1 to 120 sec. 2 port solenoid valve for dust collector () Blow tube Nozzle Clean air outlet Bag filter Small, lightweight, and compact C10-1: Outside dimensions 140 x 140, Mounting dimensions 132 x 132, Weight 32 g C0-1: Outside dimensions 120 x 100, Mounting dimensions 112 x 92, Weight 280 g Working principle (A) De-energized Right after energized Dust exhaust port Energized Dust including air inlet Supply orifice Dedicated controller Armature ON time setting rotary SW One-/two-time hitting setting The dimensions in parentheses indicate those in C0 case. Fluid from the IN side goes through the supply orifice and fills the pressure action chamber. The main valve is kept closed by the force pushing down the valve and the reaction force of the valve spring. Valve spring Pressure action chamber When power is supplied to the solenoid valve, the armature begins to be retracted, and the pilot orifice opens. The fluid filled in the pressure action chamber flows through the pilot orifice to the OUT side. Pressure action chamber Since the bleeding lowers the pressure inside the pressure action chamber, the valve pressing-down force becomes weaker than the valve pressing-up force and the valve is opened.

4 Series The VX series will be revised shortly. Selection (In the case of using as a bag filter) selection The deterrioration of /A properties due to the tube length from data B (response time/idle time) and data C (start-up speed), can be measured. Refer to this data to set energization time. Use data A (flow rate characteristics) to calculate the flow rate for each loading time separately in relation to the nozzle dia./qty., pressure, and tube. The data does not correspond to the actual bag filter operation. (In the data: Without tube and Tube length ø = How to calculate How to read the data Stop valve Pilot valve (I.D. ø6, ø10) Air tank I.D. x qty.

MPa. Moreover, the greater the air tank capacity, the greater the amount of airflow. Furthermore, the greater the nozzle's total cross sectional area, the greater the amount of airflow. While the flow volume changes according to the length of the tube, be aware that a wasted flow volume is involved during a return. Start-up speed q (MPa/ms) How to read the graph The start-up speed stands for the degree of the nozzle inside pressure rise per the unit of time. The greater it is, the stronger the shock wave from the nozzle becomes. It also means that the closing speed increases and consumption of air can be used Start-up speed θ = (A)21 Tank 41l ø6 x 610 pcs.

10 Series The VX series will be revised shortly. Precautions Be sure to read before handling. Refer to pages to for Safety Instructions and Solenoid Valve Precautions. 2 Port Solenoid Valve for Dust Collector: Series Silencer Caution 1. The silencer's response properties do not change in the initial stage, but will change due to the blockage after long use. Replace it after using about 00,000 times. This number is subject to change based on fluid quality and energization time. 2. When using a silencer, make space for silencer replacement. Selection Caution 1. The response performance and startup speed deterriorate in case of air operated type (A) as compared with a solenoid type () case. Refer to the data for pilot piping. 2. Note that for units, idle time and return time increase if the voltage is lowered. If a surge voltage suppressor is installed, the return speed decreases. Dedicated Controller for Operation: Series C Wiring Warning 1.The controller starts its output the moment the power switch is turned ON. Be aware that even if the power switch is turned OFF, power is connected to the terminal board. Caution 1. Make sure that the voltage of the power to be input matches the voltage in the controller's specifications. The voltage of the power that has been input becomes the voltage that is output to the solenoid valves. 2. Connect a ground that is rated Class 3 or greater to the power supply terminal board. 3. If the power source is, use caution to its polarity. If the polarity is incorrect, it may result in a malfunction or damage. 4. Operate at a voltage in the range of 10% to +10% of the rated voltage. Environment Caution 1. Operate under conditions that are free of vibration and impact. 2. Operate in an ambient temperature range between 0 C and 0 C. 3. Operate in an ambient humidity range between 3% to 8% (with no condensation). For further details, refer to the instruction manual in which it is explained separately
