Flow Solution
Do you offer any product lineups connected with thread type or union type other than flanges type? Yes, several types of our pumps such as our small-size magnetic pumps are available in various connections. Please contact us for more information.
What is the maximum liquid temperature the pumps can resist? Each pump has different upper temperature limits. The corrosion resistance of a pump varies depending on the relationship between the chemical concentration and temperature. Please contact us for more information by providing your pump type and application use.
Is the corrosion resistance chart available? Yes, however, the corrosion resistance chart is to provide a reference for selection of a proper pump. The chart shows corrosion resistance of pumps under restricted conditions and is subjected to change by each application.
Can you quote liquid requirements/ conditions by PH value? No, we will need more information on top of the PH value. Corrosion resistance on connection parts varies depending on: liquid type, concentration and temperature. Even though different liquid types have the same PH value, they may not be able to use the same resin. When you inquire for a quotation, please provide us with information on: liquid type, temperature and specific gravity in addition to the PH value.
What are the precautions when installing or removing the pump? Please read the safety precautions in the instruction manual before proceeding with the installation or removal. For installation, please be sure to take out the “Protection Seal” on the suction/discharge openings. For removal, please turn off the main power first. Then, disconnect cables and close the piping valve on inflow/outflow side. Remove liquid through the drain cock and dismount the pump. Please be careful not to splash liquid.
I ran the pump without filling up the priming water first. I soon realized and turned off the pump. Was I able to avoid the damage? Does the pump work OK? The pump may be damaged from dry running. Please contact us to obtain more information.
Some foreign substances may have been stuck and the pump is making abnormal noise. Will removing the foreign substances clear the noise? Even though you have removed the foreign substances, they may have damaged the inner part of the pump by abrasion. Please contact us and report the problem.
Can I use the submersible pump for highly concentrated strong acids and/or alkaline liquids? The submersible pump cannot be used for certain kinds of liquids. Please contact us to verify what kind of liquid the pump can be used for by providing us with information on: liquid type, temperature and specific gravity in addition to the PH value.
HVAC/R & Air Treatment Solution
What is refrigerated air dryer? And how it works? Refrigeration dryers work by cooling the air, so are limited to positive pressure dewpoint ratings to prevent freezing of the condensed liquid. Ideal for general purpose applications, they typically provide pressure dewpoints of 38°F (3°C), 45°F (7°C) or 50°F (10°C). Air is reheated before it re-enters the system to prevent piping from "sweating" in humid conditions. Refrigeration dryers are not suitable for installations where piping is installed in ambient temperatures below the dryer dewpoint i.e. systems with external piping.
What is absorption air dryer? And how it works? Water vapor is water in a gaseous form and is removed from compressed air using a dryer, with dryer performance being measured as pressure dewpoint. Adsorption or desiccant dryers remove moisture by passing air over a regenerative adsorbent material which strips the moisture from the air. This type of dryer is extremely efficient and typical pressure dewpoint ratings are -40°F (-40°C) or -100°F (-70°C). This means that for water vapor to condense into a liquid, the air temperature would have to drop below -40°F (-40°C) to -100°F (-70°C) respectively (the actual air temperature after an adsorption dryer is not the same as it's dewpoint). Beneficially, a pressure dewpoint of -15°F (-26°C) or better will not only prevent corrosion, but will also inhibit the growth of microorganisms within the compressed air system.
What is the purpose for line filters? Line filters are a convenient and cost effective means of ensuring your sensitive pneumatic applications are not exposed to damaging moisture and foreign contaminations . Compact size for point-ofuse applications.
How does a scroll compressor works? Two, spiral-shaped members fit together, forming crescent shaped gas pockets. One member remains stationary, while the second orbits relative to the first. As the spiral movement continues, gas is drawn in and forced toward the center of the scroll form, creating increasingly higher gas pressures and discharging the gas from the port of the fixed scroll member.
How can you tell if the rotation of a scroll compressor is running in reverse? Three phase scrolls can rotate in either direction depending on how it is wired. If running in reverse rotation the compressor will have elevated sound levels, reduced current draw and suction pressures will not drop along with a non rise in discharge pressure. The compressor will eventually trip on motor protector.
Will I damage the scroll compressor if I run it in the wrong rotation? Scroll compressors are direction-dependent, meaning they will compress in just one rotational direction. Three-phase scrolls will rotate in either direction, depending on power phasing. Here, the service technician should be aware of potential problems associated with reverse rotation. Prolonged operation in reverse result in insufficient lubrication, scroll galling and scroll set damage.
Automation & Printing Solution
What is a PLC (Programming Logic Controller)? PLC is a digital computer used for automation of electromechanical processes, such as control of machinery on factory assemble lines, amusement rides, or light fixtures. PLCs are used in many industries and machines. Unlike general-purpose computers, the PLC is designed for multiple inputs and output arrangements, extended temperature ranges, immunity to electrical noise, and resistance to vibration and impact.
General desktop computer with a remote I/O hardware combined with PLC-like programming can perform as well as PLC, do we still need PLC? Regarding the practicality of these desktop computer based logic controllers, it is important to note that they have not been generally accepted in heavy industry because the desktop computers run on less stable operating systems than do PLCs, and because the desktop computer hardware is typically not designed to the same levels of tolerance to temperature, humidity, vibration, and longevity as the processors used in PLCs. In addition to the hardware limitations of desktop based logic, operating systems such as Windows do not lend themselves to deterministic logic execution, with the result that the logic may not always respond to changes in logic state or input status with the extreme consistency in timing as is expected from PLCs
What are the differences between inverter and soft starter? A soft starter runs a motor up to speed, one uses a bypass contactor to take the soft starter out of circuit and the motor continues to run at full speed. An inverter has more control features and allows user to vary the motor speed during operation.
How do I know what size proximity sensor to use? It depends on two factors: mounting space and sensing distance. Each application has a specific amount of space available for the sensor and a requirement of how close the sensor can be mounted to the sensing object.
What is the difference between a shielded and unshielded proximity sensor? There are two major differences between a shielded and an unshielded proximity sensor. With a shielded sensor, only the face of the sensor is exposed and can be mounted flush with the sensing object. In many applications flush mounting is a requirement. With an unshielded sensor, the face and a small portion of the sides are exposed. This allows detection of objects from the side as well as the front, but does not allow mounting flush with the object as the sensor would always be activated. Unshielded proximity sensors allow for greater sensing distances.
How do I determine which type of proximity sensor output I need, NPN or PNP? PNP sensors are current sourcing devices and NPN sensors are current sinking devices. A current sourcing sensor must be connected to a current sinking input. Likewise, a current sinking sensor must be connected to a current sourcing input, so you must know the input circuitry of the device you are connecting with the sensor.
Sustainable Energy Solution
How many solar panels do I need to run my home? The size of your solar system depends on a number of factors:
  • How much electricity your home uses.
  • Angle, pitch, and direction of your roof.
  • Unobstructed roof space that is available.
In general, your solar system will not be designed to offset 100% of your electricity needs. This is because it makes more financial sense to get some of your electricity from solar energy and the rest from your utility company
How frequently should I clean my panels? The solar electricity your panels produce will naturally vary depending mostly on the weather. Most dust and debris that gets on your panels won't significantly impact solar production, and average wind and rainfall will keep your solar panels producing at near optimum. In certain situations, dust and debris can decrease your solar production by 5% to 15%, but this would most likely occur in special situations, such as a forest fire near your home. It's best to clean your panels only if you notice a significant drop in electricity production.
How long will a solar power system last? Most commercially available solar panels are capable of producing electricity for at least twenty years. Panels are expected to function for a period of 30 to 35 years
