英漢解釋

abbr.

1. pounds per square inch, differential

例句

Open TC #2. When flow of water out of TC #2 stops, the differential reading is the pressure drop. Record (must be 1 PSID or more).

開啟測試旋塞2號。當測試旋塞2號流出的水停止時，則壓差讀數(shù)就是壓降。記錄（必須是1PSID或以上）。

If the reading returns to +PSID, No. 2 shutoff valve is leaking excessively and must be replaced to test the valve.

如果讀數(shù)恢復到+PSID，則2號關閉閥泄漏過于嚴重，必須對其更換，以便進行閥門的檢測。

When dripping from bleed screw stops and PSID needle on gauge stabilizes, record the differential pressure .

當從排氣螺絲上的滴漏停止時，儀表上的PSID指針穩(wěn)定下來，則記錄壓差。

Requirement: Differential pressure across check must be 1. 0 PSID or above.

要求：通過止回閥的壓差必須在1.0PSID及以上。

Requirement: Supply pressure drop must be 1. 0 PSID or more when water flow stops from test cock No. 2.

要求：當水流從測試旋塞2號上停止時，供應壓降必須在1.0PSID及以上。

Requirement: Supply pressure drop must be 1. 0 PSID or above when water flow stops from test cock No. 2.

要求：當測試旋塞2號的水流停止時，供應壓降必須等于或大于1.

Slowly open VA and lower high side pressure about -2 PSID below the low side pressure (differential reading about -2. 0 PSID ).

慢慢開啟閥門A，并且降低高端壓力使其比低端壓力低大約-2PSID（壓差讀數(shù)大約為-2.0PSID）。
