ツクバリカセイキ List of Products and Services

This device is a fan airflow measurement system based on AMCA and JIS standards, utilizing a multi-nozzle method. It can be used for performance testing of various small fans. By combining it with the F-411 flow calculation system, automatic measurement of the fan's P-Q characteristics can be performed. In automatic measurement, parameters such as fan speed, voltage, and current can be measured simultaneously. There are two methods for switching the multi-nozzles: one is automated via software, and the other is done manually.

• Testing Equipment and Devices

This device is used to test the P-Q characteristics of fans with very small airflow. JIS-B-8330 "Fan Performance Testing Methods" is not suitable for testing fans with very small airflow, such as those used for cooling laptops. By using a mass flow controller in the airflow detection section, testing of fans with very small airflow has been made possible.

• Testing Equipment and Devices

It is the most theoretically superior and reliable method for mechanically measuring the flow rate of gases and liquids. The flow rate within a pipe can also be determined from the pipe's cross-sectional area and average flow velocity. The tip of a standard Pitot tube has a total pressure port, and a static pressure port on the side. By inserting the Pitot tube into the flow pipe as shown in the diagram, the difference between total pressure and static pressure, that is, dynamic pressure, is measured with a manometer, and the flow velocity is calculated using the following formula.

• Analytical Equipment and Devices

"WAZUKA" is a leak area tester that measures the airtightness of closed spaces and calculates the leak area based on the pressure difference between the inside and outside. It emphasizes portability, resulting in a compact and lightweight device. It measures the leakage amount in response to the pressure applied to the workpiece and calculates the leak area in a circular window shape, displaying the results in real time.

• Testing Equipment and Devices

"Shizuka" is a measurement system that utilizes a noise plenum for small fans, as specified in the JBMS 72 series. Centered around the Tsukuba Rika Seiki Co., Ltd. F4115 series "noise plenum," it has been further expanded to enable easy measurement of noise, vibration, and shaft power. This series targets fan motors (types where the motor and fan are directly connected). When using this series, it is assumed that the PQ performance of the fan being tested has already been measured using a fan airflow and low airflow measurement system, and that the motor input is known through the shaft power measurement system.

• Testing Equipment and Devices

Our company is capable of constructing a system that combines a 5-hole Y-ometer, a traverse, and a computer to measure the distribution of flow direction and velocity while moving measurement points consecutively.

• Analytical Equipment and Devices

The pressure value can switch between time average display and display units (mmH2O/Pa). Additionally, it is equipped with an analog output terminal (0-5V) and an RS-232C port on the back, allowing it to connect to other information devices to capture data.

• Analytical Equipment and Devices

To measure the differential pressure of devices such as Pitot tubes and orifices at multiple points with a single differential pressure gauge, a switching cock is used.

• Analytical Equipment and Devices

In measurements such as flow velocity distribution, boundary layer measurements, and average airflow measurement using the JIS 5-point method, it is necessary to precisely move the pitot tube and correlate the measurement values with their positions.

• Analytical Equipment and Devices

This device measures the flow pressure loss characteristics, which is an important performance evaluation item of the catalyst support incorporated in automotive exhaust gas purification systems. It consists of a wind tunnel, a blower, and a control computer.

• Analytical Equipment and Devices

This device is an apparatus for testing the heat dissipation performance of automotive radiator cooling systems based on JIS-D-1614.

• Wind Speed/Volume Meter

The most widely used type of wind tunnel for wind tunnel experiments is the circulating flow type, which has cross-sectional shapes of square, octagonal, and circular.

• Wind Speed/Volume Meter

It is most suitable for intuitively understanding aerodynamic flow phenomena and can be easily used for educational and fundamental flow experiments.

• Wind Speed/Volume Meter

It can be used as a standard instrument with a wind speed distribution of less than 1% and turbulence of less than 1%. It is also possible to add a rotating device for calibration purposes, such as for a Yomeeter. The compact type has been miniaturized for installation in a laboratory, with turbulence at 0.5%.

• Wind Speed/Volume Meter

It is used to predict and solve various wind-related issues such as wind gusts occurring around high-rise buildings, wind pressure acting on buildings, and the dispersion of urban pollutants.

• Other environmental analysis equipment

In fields such as aviation, vehicles, automobiles, and fluid machinery, it is necessary to clarify and verify the mechanisms of noise generation using wind tunnel experiments and CFD (Computational Fluid Dynamics) in order to develop environmentally friendly (Ecology) and economically viable (Economy) ECO products by reducing aerodynamic noise and improving efficiency.

• Other Auto Parts

Water is supplied to the overflow tank by a pump, and static water at a constant pressure flows into the open water channel.
