MPa Viscosity Characteristics: Built-in Solenoid Valve/Air Operated Viscosity Characteristics (Flow rate correction for viscous fluids) SUP =.7 MPa SUP =.5 MPa SUP =.5 MPa SUP =. MPa Calculation of Air Consumption Selection from Viscosity Characteristic Graph Selection from Flow Rate Characteristic Graph Required specification example Find the pilot air pressure for a discharge rate of 6 ml/min and a discharge pressure of.15 MPa for builtin solenoid valve type. <The transferred fluid is clear water (viscosity of 1 mpa s, specific gravity of 1.) and solenoid valve cycle is 5 Hz.> When the total pump head is required instead of the discharge pressure, a discharge pressure of.1 MPa corresponds to a total pump head of 1 m. Selection procedure 1. First, mark the intersection point for a discharge rate of 6 ml/min and a discharge pressure of.15 MPa.. Find the pilot air pressure for the marked point. In this case, the point is between the discharge curves for.5 MPa and.5 MPa, and based on the proportional relationship to these lines, the pilot air pressure for this point is approximately.4 MPa. Find the air consumption for operation with a 5 Hz switching cycle and pilot air pressure of.5 MPa from the air consumption graph. Selection procedure 1. Look up from the 5 Hz switching cycle to find the intersection with SUP =.5 MPa.. From the point just found, draw a line to the Y-axis to find the air consumption. The result is approximately 1 L/min (ANR). 1. Flow rate characteristics are for clear water (viscosity of 1 mpa s, specific gravity of 1.), no piping for suction and discharge.. The amount of discharge differs greatly depending on properties (viscosity, specific gravity) of the fluid being transferred and operating conditions (pump head, transfer distance), etc. 1. The air consumption differs greatly depending on properties (viscosity, specific gravity) of the transferred fluid and operating conditions (pump head, transfer distance), etc. Required specification example Find the pilot air pressure and pilot air consumption for a discharge rate of 7 ml/min, discharge pressure of.15 MPa, and a viscosity of 15 mpa s. Selection procedure 1. First, find the ratio of the amount of discharge against clear water when viscosity is 15 mpa s from the graph to the left. It is determined to be 45%.. Next, the viscosity of 15 mp s and the discharge rate of 7 ml/min in the required specification example are converted to the amount of discharge for clear water. Since 45% of the clear water discharge is equivalent to 7 ml/min in the required specifications, 7 ml/min.45 = approximately 6 ml/min, indicating that a discharge rate of 6 ml/min is required for clear water.. Finally, find the pilot air pressure and pilot air consumption based on the flow rate characteristic graphs.

6 1A Series Working Principle: Built-in Solenoid Valve/Air Operated Pump chamber Discharge port < OUT> Suction port < IN> Diaphragm Driving chamber Return spring Built-in solenoid valve (-port valve) Only 11A The 11A air-operated type is not equipped with a built-in solenoid valve. Prepare a -port solenoid valve separately. Air supply port <AIR SUP> Air exhaust port <AIR EXH> Piping and Operation: Built-in Solenoid Valve/Air Operated When air is supplied with the built-in solenoid valve turned ON (energized), air enters the driving chamber and the diaphragm moves to the left. Due to this movement, the fluid in the pump chamber passes through the upper check valve and is discharged to the discharge port < OUT>. When the solenoid valve is turned OFF (de-energized), the air inside the driving chamber is evacuated to air exhaust port <AIR EXH>, and the diaphragm is moved to the right by the return force of the return spring. Due to this movement, the fluid on the suction port < IN> passes through the check valve and is sucked into the pump chamber. The 111A transfers the fluid continuously by suction and discharge in turn by repeating ON/OFF of the built-in solenoid valve. The 11A air-operated type is operated by the ON/OFF operation of an external solenoid valve. Maintenance Parts Basically, it is not recommended to disassemble the process pump. However, if this is necessary, be sure to follow the instructions in the maintenance procedure. When carrying out this work, wear appropriate protective equipment. 1A Series Description 1A series 111A 11A Diaphragm kit KT-1A-9 KT-1A- Check valve kit Port set Packing kit KT-1A-1 KT-1A-7 Note) KT-1A-4 Foot kit Solenoid valve kit KT-1- SYJ14M-5H-Q KT-1A-4 Note) One of Nil, F or N is entered as a thread symbol.

Supply clean air that has passed through a filter or mist separator, etc., to the air supply port <AIR SUP>. Air that contains debris or drainage, etc., will have an adverse effect on the built-in solenoid valve, and will cause malfunction of the pump. Maintain the proper tightening torque for fittings or mounting bolts. Looseness can cause problems such as liquid or air leakage, while over-tightening can cause damage to threads or parts, etc. Suction port < IN> Solenoid valve lead wires Air supply port <AIR SUP> Air exhaust port <AIR EXH> (Silencer: Option) Recommended Valve () 11A SYJ54 Suction port < IN> Circuit example/built-in solenoid valve Operation 1. Connect air piping to the air supply port <AIR SUP>, and connect piping for transferred fluid to the suction port < IN> and the discharge port < OUT>.. Connect the solenoid valve lead wires to a 4 VDC power supply. Red is (+) and Black is ( ). (The 11A air-operated type must be equipped with a separate -port solenoid valve.). Using a regulator, set the pilot air pressure within the range of. to.7 MPa. By continuously turning the 4 VDC power ON/OFF, the fluid flows from the suction port < IN> to the discharge port < OUT>. The pump performs suction with its own power even without priming. Idle run of the pump Air supply port <AIR SUP> shall be minutes or less for the intake of the liquid. 4. To stop the pump turn OFF the 4 VDC power. Also, be sure to turn OFF the power when the discharge side is closed. If the pump is stopped for a long time, exhaust the air from the <AIR SUP> port. The manual override pin is used for manual operation when there is no electric power. Each time it is pressed, there is one reciprocal operation. For the 11A air-operated type, stop the -port solenoid valve, and be sure to discharge air from the pump. Although the pump can be stopped by closing the throttle installed in the discharge side, avoid stopping operation for a long time. If the valve opens/closes suddenly, surge is generated, shortening the pump life. When the tank for fluid suction side is empty, stop operating the pump immediately.

SUP =.5 MPa SUP =.5 MPa SUP =. MPa Selection from Flow Rate Characteristic Graph Required specification example Find the pilot air pressure for a discharge rate of 4 ml/min and a discharge pressure of.15 MPa. <The transferred fluid is clear water (viscosity 1 mpa s, specific gravity of 1.) and solenoid valve cycle is 5 Hz.> When the total pump head is required instead of the discharge pressure, a discharge pressure of.1 MPa corresponds to a total pump head of 1 m. Selection procedure 1. First, mark the intersection point for a discharge rate of 4 ml/min and a discharge pressure of.15 MPa.. Find the pilot air pressure for the marked point. In this case, the point is between the discharge curves for. MPa and. MPa, and based on the proportional relationship to these lines, the pilot air pressure for this point is approximately.5 MPa. Calculation of Air Consumption Find the air consumption for operation with a 5 Hz switching cycle and pilot air pressure of.5 MPa from the air consumption graph. Selection procedure 1. Look up from the 5 Hz switching cycle to find the intersection with SUP =.5 MPa.. From the point just found, draw a line to the Y-axis to find the air consumption. The result is approximately 7.5 L/min (ANR). 1. Flow rate characteristics are for clear water (viscosity of 1 mpa s, specific gravity of 1.).. The amount of discharge differs greatly depending on properties (viscosity, specific gravity) of the transferred fluid and operating conditions (pump head, transfer distance), etc. Selection from Viscosity Characteristic Graph Required specification example Find the pilot air pressure and pilot air consumption for a discharge rate of 18 ml/min, discharge pressure of.15 MPa, and a viscosity of 15 mpa s. Selection procedure 1. First, find the ratio of the amount of discharge against clear water when viscosity is 15 mpa s from the graph to the left. It is determined to be 45%.. Next, the viscosity of 15 mp s and the discharge rate of 18 ml/min in the required specification example are converted to the discharge rate for clear water. Since 45% of the amount of clear water discharge is equivalent to 18 ml/min in the required specifications, 18 ml/min.45 = approximately 4 ml/min, indicating that a discharge rate of 4 ml/min is required for clear water.. Finally, find the pilot air pressure and pilot air consumption based on the flow rate characteristic graphs.
