Procedure for Changing the Shaft on a Siemens Combustion Controls SQM5 Actuator

Watch this video to see how easy it is to change or replace the shaft in a Semens SQM5 actuator. 

The Siemens SQM5 reversing actuators are used for the positioning of flow control valves, butterfly valves, dampers, or any application requiring rotary motion. The SQM5 actuators accommodate control input signals of 4 to 20 mA, 0 to 135 Ω, 0 to 10 Vdc, 0 to 20 mA, position proportional and floating control. The available output signals include 4 to 20 mA, 0 to 135 Ω, 0 to 10 Vdc, 0 to 20 mA, and 0 to 1000 Ω. SQM5 actuators are available with up to six internal, easily adjustable switches.

Airflow Control Within Close Tolerances Saves Money

Airflow Control Within Close Tolerances Saves Money

In drying and coating processes in the pharmaceutical, food and beverage, chemical, petrochemical, and mining sectors, millions of dollars are lost daily - in fluidized beds, rotary drums, flash dryers, kilns, and similar processes. Because of improper air and product feeds, these devices' failure can cause validation problems, causing downtime, re-validation, and loss of both goods and profits. It's vital to control airflow through these devices.

PROBLEM

How can vital processes and devices that need to work within tight tolerances over a broad operating range be supported with continuous air mass flow at a regulated air temperature?

1) Improving Production Efficiency

The off-specification product must be recycled or wasted. This process is too costly, especially in the validated industries. Precise control of airflow and air temperature is essential to maintain high product quality, reduce waste, and increase uptime.  The performance of many processes would benefit from measuring the mass flow of process air.  Also, limited flow meter turndown often constrains operational flexibility - primarily when requirements cover a wide range of operating conditions.  

2) Dealing with Limited Straight Pipe Runs

Airflow meters incorporated into process equipment are often inaccurate due to the short upstream and downstream straight pipe run.  The installation of a good straight run can quickly become problematic in tight quarters, so other solutions are needed.

3) Reducing Plugging and Coating

Most process equipment designs do not include relatively dirty exhaust flow measurements, even though they can provide significant operational benefits. They are often not included because exhaust flow meters can become coated and plugged when particulates are present — reducing flow meter accuracy.  

Products from Air Monitor solve these issues by enhancing the reliability of your airflow meters by improving their accuracy over a wide range of flow rates, thus improving the process's efficiency, improving the product's consistency, and increasing production rates to reduce fuel spending.

The FIREYE® BurnerPRO™ Microprocessor-Based Integrated Burner Management Control

Fireye BurnerPRO

The Fireye BurnerPRO is a compact, microprocessor-based, primary flame safeguard control system designed to provide the proper burner sequencing, ignition, and continuous flame monitoring for on-off, multi-stage, or modulating burners used in commercial heating and process equipment firing oil and gas fuels. The system is designed for non-permanent operations that require burner recycling at least once every 24 hours. Flame monitoring for the UV version is accomplished by the built-in amplifier and compatible UV scanner. Control functions and timings are factory set via special microcontroller firmware.

Through seven SMART LEDs, the control provides current operating status and lockout information in a safety shutdown event.  A complete BurnerPRO system includes the BP110/230, flame scanner, and wiring base. 

The BurnerPRO performs a safety self-test on every start. If a flame is detected before the startup or during the purge cycle, the fuel valves will not be energized, and the control locks out. The LEDs and alarm terminal is used to annunciate the presence of a lockout condition.

Additional functions of the BurnerPRO include:

  • Non-volatile lockout capability
  • Proof of fuel valve closure
  • Air-flow proving
  • A run/check feature allows the operator to stop the program sequence in differentpositions (Purge, Ignition, PTFI and MTFI)
  • Remote and local Reset
  • One second flame failure response time
  • Smart LEDs provide on board diagnostic lockout information
  • Real-time internal diagnostics for added safety integrity
  • Extended temperature operation (-40°C to 60°C) with an over-temp inhibit feature
  • High capacity relay contacts
