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).

开启测试旋塞2号。当测试旋塞2号流出的水停止时，则压差读数就是压降。记录（必须是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.

如果读数恢复到+PSID，则2号关闭阀泄漏过于严重，必须对其更换，以便进行阀门的检测。

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

当从排气螺丝上的滴漏停止时，仪表上的PSID指针稳定下来，则记录压差。

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

要求：通过止回阀的压差必须在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：当水流从测试旋塞2号上停止时，供应压降必须在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：当测试旋塞2号的水流停止时，供应压降必须等于或大于1.

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

慢慢开启阀门A，并且降低高端压力使其比低端压力低大约-2PSID（压差读数大约为-2.0PSID）。
