閥進(jìn)行調(diào)節(jié)，盡量使泵運(yùn)行工況接近泵的設(shè)計(jì)點(diǎn)。
(4)、均勻地?cái)Q緊填料壓蓋上的壓緊螺母，使液體呈滴狀流出，同時(shí)注意填料腔處的溫升；
(5)、當(dāng)停止水泵運(yùn)轉(zhuǎn)時(shí)，要先關(guān)閉真空表及壓力表的旋塞和排水管路上的閘閥，然后切斷電動機(jī)電源。當(dāng)所處環(huán)境溫度低于0℃時(shí)，則應(yīng)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(shí)，應(yīng)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(yùn)轉(zhuǎn)：
(1)、水泵軸承最高溫度不應(yīng)超過75℃：
(2)、潤滑滾動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；潤滑滑動軸承的機(jī)械油(N10～N32)，油位高度要控制，防止油環(huán)不上油；
(3)、填料磨損時(shí)可適當(dāng)壓緊填料壓蓋，若磨損過多應(yīng)加以更換；
(4)、定期檢查彈性聯(lián)軸器部件，注意泵和電機(jī)軸承溫升；
(5)、運(yùn)轉(zhuǎn)過程中，如發(fā)現(xiàn)噪音或其他不正常的聲音時(shí)，應(yīng)立即停車，檢查原因，加以消除；
(6)、不得任意提高泵的轉(zhuǎn)速，但可降低轉(zhuǎn)速使用，本型泵額定轉(zhuǎn)速n，流量Q，揚(yáng)程H，功率N，倘若降低轉(zhuǎn)速為n1，則流量為Q1，揚(yáng)程為H1，功率為N1，可用下列公式換算：

pump, the cocks on the pipe passage way which connect
the pump should be turned off. Then start the motor. It is not allowed to turn
on the motor until the running speed is normal, and then open gradully the brake
valve until the suction water of the two sides reachs balance.
4. Screw homogenizenously
the nuts on the pump packing gland so as to the leakage of liquid is little, at
the same time, pay more attention
to the packing case temperature rising.
5. While stopping the pump
running, first turn off the cocks
of the vacuum gauge and manometer and tuna off the brake valve on the discharge
pipe passage way. If the anabient temperature is low, the coach under the pump casing should
be loosen to drain away the rest water so as to keep the pump casing from being
split by forst.
6. If it will not be used
for a long time, the pump must be disconnected and all the parts should be kept
dry, and smear the machining face
with rust- proof
grease
oil.
b. Running:
1. The temperature of the
pump beating 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 rumfing, if any noise or unnormal sounds are
heared, stop the pump immediately, and look for the cause, then clear out.
6. It is not allowed to increase the
rumfing speed want only, but you can decrease the running speed of the pump for
working. The performance paranaet of the pump changes as the following. (Please
see the formula as follow)
