摘要:
A sprayer system (10) has a first liquid line (160) and a second liquid line (170), both in fluid communication a row. In an embodiment, the row has a first pulse width modulated (PWM) valve (191) in fluid communication with the first liquid line (160) and a second PWM (191) in fluid communication with the second liquid line (170). The PWM valves may both be connected to same nozzle (195) or they may be connected to separate nozzles. The PWM valves may be arranged in a common housing. In an alternative embodiment, each row has a three-way valve (193) in fluid communication with the first and second liquid lines (160, 170). The three-way valve (193) is in fluid communication with a PWM valve (191), which is in fluid communication with a nozzle (195). The sprayer system can be used to apply one chemical to an entire field through the first liquid line and selectively apply an additional chemical to individual locations in the field through the second liquid line.

A configurable nozzle includes a nozzle body having a reception chamber configured to receive an application mixture. The nozzle body includes a nozzle orifice. At least one orifice assembly is coupled with the nozzle body, the at least one orifice assembly includes an orifice plate movably coupled with the nozzle body. The orifice plate extends along at least a portion of the nozzle orifice, and movement of the orifice plate changes one or more of the size or shape of the nozzle orifice. An orifice actuator is coupled with the orifice plate, and the orifice actuator is configured to move the orifice plate.

An agricultural sprayer having a liquid supply conduit for directing selectively controllable pressurized liquid to a plurality of spray nozzle assemblies. Each nozzle assembly includes a nozzle body having a respective orifice member having an inwardly tapered conical section communicating with a smaller diameter discharge orifice. Each respective orifice member is made of a resilient and pressure responsive deformable material such that upon an increase in the pressure of the liquid supply said liquid flow passage and discharge orifice thereof can be altered to increase the rate through said orifice member and nozzle body by at least 75 percent and upon interruption of the supply of pressurized liquid to the orifice member the orifice member liquid flow passage and discharge orifice return to their original shape.

A system for coating a heat transfer tube (105) for a condenser is disclosed. The system simplifies a process of coating the heat transfer tube (105), and is able to uniformly coat a plurality of heat transfer tubes (105). In addition, the system is economically feasible in that coating solution can be reused by collecting and circulating it. Due to super-hydrophobic coating, the size of a droplet condensed on the surfaces of the heat transfer tubes (105) coated by the system can be reduced, and a condensation heat transfer coefficient can be increased.

Spray systems and control systems for use with spray systems are provided. A method of detecting fluid flow through a nozzle coupled in fluid communication with a solenoid valve including a solenoid coil and a poppet is provided. The method generally includes (1) dispensing fluid through the solenoid valve and the nozzle, (2) de-energizing the solenoid coil to close the solenoid valve and control a fluid flow through the nozzle, (3) determining a closing time of the solenoid valve based on a signal from a poppet measuring device, and (4) determining a fluid flow value based on a time delay between the de-energizing the solenoid coil and the closing time.

An injection jet (437) includes a body (601) having a first (701) and a second (703) passage disposed therein for channeling a fluid to a working element (303). The first passage (701) remains fluidly separated from the second passage (703). A system includes the injection jet (437) along with a main reservoir (405) and an emergency reservoir (415). The first passage (701) is in fluid communication with the main reservoir (405), while the second passage (703) is in fluid communication with the emergency reservoir (415). The system operates in a standard mode and an emergency mode. Both the first passage (701) and the second passage (703) are configured for jointly supplying fluid to the working element during standard mode. The second passage is configured for independently supplying fluid to the working element (303) during emergency mode.

摘要:
The present invention relates to a method for dynamically supplying coolant to a cooling device, in particular at least one spray bar, for cooling metal strip or other rolled stock. According to the method, a pre-accelerated stream of coolant is provided, which passes by the cooling device (1) and is fed into a return (3). Furthermore, the presence and/or the temperature of a metal strip or other rolled stock to be cooled is monitored and, depending on the presence and/or the temperature of the metal strip or the other rolled stock, the stream of coolant is diverted to the cooling device (1), wherein, instead of passing by the cooling device (1) and being fed into a return (3), the stream of coolant is fed to the cooling device (1) for cooling the metal strip or the other rolled stock. The present invention also comprises a corresponding device for carrying out the method.
