閥進行調節,盡量使泵運行工況接近泵的設計點。

                      (4)、均勻地擰緊填料壓蓋上的壓緊螺母,使液體呈滴狀流出,同時注意填料腔處的溫升;

                      (5)、當停止水泵運轉時,要先關閉真空表及壓力表的旋塞和排水管路上的閘閥,然后切斷電動機電源。當所處環境溫度低于0℃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)、潤滑滾動軸承用的鈣基黃油的數量以占軸承體空間的1/31/2為宜;潤滑滑動軸承的機械油(N10N32),油位高度要控制,防止油環不上油;

                      (3)、填料磨損時可適當壓緊填料壓蓋,若磨損過多應加以更換;

                      (4)、定期檢查彈性聯軸器部件,注意泵和電機軸承溫升;

                      (5)、運轉過程中,如發現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,但可降低轉速使用,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Q1,揚程為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)
