的溫升；
(5)、當停止水泵運轉時，要先關閉真空表及壓力表的旋塞和出水管路上的閘閥，然后切斷電動機電源。當所處環(huán)境溫度低于O℃時，則應將泵體下部的四方螺塞打開，去掉剩水，以免凍裂；
(6)、長期停止使用時，應拆開水泵，將零件上的水擦開，在加工表面涂上防銹油保管好。
2、運轉：
(1)、水泵軸承最高溫度不應超過75℃；
(2)、潤滑軸承用的鈣基黃油的數(shù)量以占軸承體空間的1／3～1／2為宜；
(3)、填料磨損時可適當壓緊填料壓蓋，若磨損過多應予以更換；
(4)、定期檢查彈性聯(lián)軸器部件，注意泵和電機軸承溫升；
(5)、運轉過程中，如發(fā)現(xiàn)噪音或其他不正常的聲音時，應立即停車，檢查原因，加以消除；
(6)、不得任意提高泵的轉速，但可降低轉速，如本型泵額定轉速n，流量Q，揚程H，功率N，倘若降低轉速為n1，則流量為Qz，揚程為H1，功率為N1，其相互關系可用下列公式換算：

running
speed is normal, and then open gradully the brake valve untitl the suction water
of the two sides reaehs to balance.
4. Screw homogenizenously the nuts
on the primp packing gland so as to the leakage of liquid is little, at the
same time, pay more attention to the packing ease temperature rising.
5. While stopping the pump runing,
first turn off the cocks of the vacuum gauge and manometer and turn off the
brake valve on the discharge pipe passage way. ff the ambient temperature is
low, the coach un- der the pump casing should be loosen to drain away the rest
water so as to keep the pump easing from being split by frost.
6. ff it will not be used for a long
time, the pump must be disconnected and all the parts should be kept dring, and
smear the machining face with rust - proof
grease
oil.
Running:
1. The temperature of the pump
bearing should not be exceeded 75℃.
2. The suitable quantity of the
good Ca-bade grease which is used to lubricate the bearing occupies 1/3 to 1/2
space of the bearing body, and it should be changed periodicaly.
3. When the paking worn, tighten the packing gland properly or
change it if it is necessary.
4. Check the flexible coupling part, care
more for the motor bearing temperature rising.
5. During running, if any noise or unnormal sounds are
h,eared, stop the pump immediately, and look for the cause, then clear out.
6. It is not allowed to increase
the running speed wantonly, but you can decrease the running speed of the pump
for working, The performance Paramet of the pump changes as the following.
(Plese see the formula as follow) :
