HomeExplanation>Usage varieties(Vibration proof and heatproof)

Heatproof type

①【Environmental temperature】After it confers, the specification is decided when it makes to the range of 5~80℃, and this is exceeded.

②【Other condition】Common type's condition ②③④⑤ is quoted

③【SignH】It displays and the kind according to the usage is shown.

Vibration proof type(Excitement vibration proof type)

①【Pulse or vibration】It is time when it joins the pulse and the vibration that the indicator that exceeds the accuracy allowance difference is swung, and the extent is concretely made the following range.

  【Range of pulse】It must not be an accuracy allowance difference or less and there be no abnormality in function after applying the pulse pressure of 1Hz or less continuously within the range in the table.

Maximum pressureMPa Range of pulse pressure
(% to maximum pressure)
Frequency
Vibration proof type {Excitement vibration proof type}
Ten or less 30~70 15000 {500000}
60 or less exceeding ten. 40~60 10000
160 or less exceeding 60. 40~60 5000

  【Oscillating range】 The resonant oscillation within the range in the table. a right and left and 33 upper and lower directions install it in regular posture
 It must not be an accuracy allowance difference or less and there be no abnormality in function for each two hours addition later 6.9m/s and ±30Hz when there is no resonance point in this.

Vibration frequency Amplitude mm Acceleration m/s^2
1~13.2 1.0
13.2~100 ±6.9

②【Other condition】
Common type's condition ②③④⑤ is quoted

③【SignV】
It displays and the kind according to the usage is shown.

Vibration proof for steam type

①【Condition】It has both conditions of the vibration proof type for steam.

②【SignMV】It displays and the kind according to the usage is shown.

Heatproof and vibration proof type

①【Condition】It has both conditions of the vibration proof type for steam.

②【SignHV】It displays and the kind according to the usage is shown.

※{ } It doesn't correspond to JIS B 7505 by what enacted as our standard for the performance gain.
