1264i WL powder feeder

The 1264i type powder feeder is an important innovative update design based on the world famous 1264 type powder feeder. The 1264 i powder feeder organically combines the latest electronic technology, ergonomics and 1264 user's suggestions in the world, which can save time, money and improve the stability of powder feeding. The 1264 i powder feeder is equipped with a touch screen operator interface terminal (OIT) with advanced technology, which can be placed remotely. PLC is used for process control, and the capacity of the powder storage tank is increased by 30%. The user-friendly operator interface terminal (OIT) has a variety of technical functions, such as maintenance screen, plasma/HVOF mode selection, total operation time, operation time reset, etc. The electric blanket with settable temperature can keep the powder warm and help prevent the powder from getting wet. The 1264WL powder feeder also has the above performance, and also has the closed-loop weight metering feedback control function.

It is important to increase the effective spraying time that 1264i not only increases the volume by 30%, but also the powder storage tank can be replaced quickly. This replaceable powder storage tank can be designed to store the remaining powder, or is specially used for certain specific powder to prevent cross contamination. When it is necessary to change the powder, the rapid replacement of the powder storage tank increases the effective operation time of spraying.

The quick change design of the powder storage tank makes the powder change easier and faster, and the effective operation time is longer

The 1264i powder feeder is a closed loop pressure unit specially designed for thermal spraying applications. Based on the proven volume conveying technology, 1264i is an economical powder feeder for powder thermal spraying process. Its proven design has become a model in the thermal spraying industry, and it has incomparable powder delivery accuracy and reproducibility.

A "super" powder feeder with high-end technology and advanced design

Working principle: The operation of the 1264i powder feeder is based on the principle of volume metering. The powder feeding rate is directly controlled by controlling the rotation speed of the powder feeding plate. During operation, the slot on the powder tray is filled with powder. The rotation of gravity, powder carrier gas and variable-speed powder feeding tray drives the powder to enter the powder feeding pipe. The inert carrier gas pressurizes the powder storage tank and then transports the powder to the thermal spray gun through the pipeline. The RPM high limit/low limit alarm value that can be set by the user will inform the operator when the RPM of the powder tray exceeds the limit. The powder feeder is not sensitive to back pressure, and the rated pressure is up to 150PSI (1034kPa).

Control the powder feeding rate by weight

A major project of the new design is to replace the 1280 type powder feeding rate controller. The birth of 1264WL powder feeder has raised the reliability and weight reduction control function to a new level. By quickly calculating the weight reduction over time, 1264WL automatically places the powder feeder in the pre-programmed powder feeding rate control and maintains this powder feeding rate throughout the operation cycle. The closed-loop control of powder feeding rate can estimate the change of powder bulk density, and maintain the desired powder feeding rate by adjusting the rotational speed (RPM) of the powder feeding plate. In this way, the uncertainty related to the control of the disc speed powder feeding rate is eliminated.

Due to the powerful PLC control program of 1264WL, the time to reach the predetermined powder feeding rate is very short. This program uses an algorithm based on powder loose density to quickly control the powder feeding rate at the set value, and synchronously adjust the RPM of the powder feeder to maintain the set speed. Considering the rapid change of powder feeding parameters, the 1264WL allows the operator to store the set value and powder bulk density data in its memory.

1264WL also has other functions, such as the user-settable alarm of low powder quantity and high/low powder feeding rate, which can tell the operator that the powder storage tank is going to be empty or the powder feeding rate is going to exceed the corresponding set value.

Both the 1264i and 1264WL are equipped with maintenance (PM) screens, which can be set by the user. The internal access is simple, so that the maintenance can be easily carried out and completed as scheduled, and the downtime is minimized.

Both 1264i and 1264WL can be used as independent units, or as a component combined with the advanced JP-8000 HP supersonic, 7700UPC plasma, or GTS multi-process system.
