USE OF CHEMICAL COMPONENTS Spraying Systems Co. does not manufacture or supply any of the chemical components used in this equipment and is not responsible for their effects. Because of the large number of chemicals that could be used and their different chemical reactions, the buyer and user of this equipment should determine compatibility of the materials used and any of the potential hazards involved. -
Page 5: Es250+ Overview
SECTION 3 ES250+ OVERVIEW 3.1 ELECTROSTATICS SPRAYING OVERVIEW In electrostatic spraying, a negative charge is introduced into a fluid in the nozzle body through a central charging elec- trode, which causes the fluid to acquire a negative charge. When this negative charge is applied to the fluid, this causes the fluid molecules to repel each other, following the principle that molecules with opposite charges will attract and molecules with like charges will repel. -
Page 6: Electrostatic Spray Control Panel
SECTION ELECTROSTATIC SPRAY CONTROL PANEL SPRAY CONTROL PANEL - 250TS25000051W0 ® The AutoJet ES250+ Electrostatic Spray Control Panel supplies the required voltage to the electrostatic nozzles via a 30,000 VDC (40 kVDC) positive polarity HVPS. At the control panel, the operator can adjust the applied voltage, pump frequency and start or stop the system modes. -
Page 7: Connecting The High Voltage Cable
4.2 CONNECTING THE HIGH VOLTAGE CABLE WARNING: Before installation, ensure that the spray control panel is turned off and power is disconnected. CABLE CONNECTION PROCESS • Remove cable cover by removing two socket head cap screws (Figure 4.2-1) • Press high voltage cable onto the electrode (Figure 4.2-2) •... -
Page 8: Fluid Reservoir Assembly
SECTION 5 FLUID RESERVOIR ASSEMBLY 5.1 MOUNTING AND POSITIONING FLUID RESERVOIR ASSEMBLY The fluid reservoir assembly includes pumps, an air pressure regulator with a built in particle filter, and the fluid reser- voir tank. The piston pump powers lubricant delivery from the reservoir to the nozzle. The pressure regulator with built in parti- cle filter provides clean, controlled air pressure to the pump for its operation. -
Page 9: Fluid Reservoir Connections
5.2 FLUID RESERVOIR CONNECTIONS FLUID LINES The fluid line originates from the fluid reservoir and connects to the pump. The line then runs out to the electrostatic nozzle through 1/4 in. OD push-to-connect fittings. AIR LINES The air input connects to the air pressure regulator using 1/4 in. NPT. The regulator connects to the pump through 1/4 in. -
Page 10: Lubricant Pump
5.3 LUBRICANT PUMP System fluid delivery is powered by a small piston pump. This type of pump is commonly used in applications when low flow rates are desired for chain lubrication. The system includes an air pressure regulator assembly to power the pump. -
Page 11: Components
5.4 COMPONENTS FLUID RESERVOIR COMPONENTS The air pressure switch, solenoid cable, and fluid level float switch are all wired back to the Electrostatic Spray Control Panel. • The air pressure regulator (Figure 5.4-1) connects Block J9 and Input 9 connecting the black and white wires to terminals 17 and 18 respectively. -
Page 12: Particulate Filter
5.6 PARTICULATE FILTER The particulate filter (five micron) is included to prevent moisture and dirt from entering the solenoid valve by way of the compressed air line. Excess moisture will condense inside the Figure 5.6: attached polycarbonate bowl. The polycarbonate bowl water level can be viewed through Particulate Filter the slots of the metal bowl protector. -
Page 13: Electrostatic Chain Oiler Spray Nozzle
SECTION 6 ELECTROSTATIC CHAIN OILER SPRAY NOZZLE 6.1 NOZZLE OVERVIEW ELECTROSTATIC CHAIN OILER SPRAY NOZZLE The Electrostatic Chain Oiler Spray Nozzle delivers the electrostatically charged fluid to the target. Using the spray control panel, operators can adjust the voltage level applied to all nozzles that are connected to that panel. Each nozzle is connected to its own individual piston pump, which allows for some independent adjustment of pump flow rate. -
Page 14: Nozzle Connections
6.2 NOZZLE CONNECTIONS Fluid Line Fluid line tubing must be made from a material that is compatible with the fluid being sprayed. Tubing must be rigid enough to be compatible with the 1/4 in. (6.4 mm) OD push-to-connect fittings that are supplied with the nozzle assembly. -
Page 15: Nozzle Configuration And Adjustment
6.4 NOZZLE CONFIGURATION AND ADJUSTMENT ELECTROSTATIC VOLTAGE The electrostatic nozzle is rated for between 0–40,000 volts. This voltage range allows for variation in fluid viscosities and allows for adjustments to both spray pattern and drop size. WARNING: Do not exceed voltage rating for nozzle assembly. Serious injury or death may occur. PRIMING THE ES250+ 1. -
