5)、當周圍的環(huán)境溫度達到30℃時，軸厚溫度不能超過90℃，當溫度再升高，軸承溫壓最多不應(yīng)超過100℃：
6)、使用稀油潤滑，要定期檢查油位；油脂潤滑的深溝球軸承不需要維護。
7)、檢查聯(lián)軸器上的彈性元件，一旦磨損，應(yīng)立即更換：
8)、如果密封、冷卻、潤滑液不是用工作介質(zhì)，必須保證使用的液壓比進口壓力高1.0～2.0巴。
3、停止：
1)、泵停止運轉(zhuǎn)時，先關(guān)閉出口閥，然后切斷電源：
2)、關(guān)閉輔助管路。泵的軸封即使在停機狀態(tài)也要用潤滑油密封：
3)、在冰凍或長期停止使用時，應(yīng)排除泵及管路中的介質(zhì)，以免凍裂。
4)、當輸送的介質(zhì)為對踺康有害的液體時，應(yīng)將泵和管路內(nèi)介質(zhì)盡快排盡。

to be
pumped. In the case of both gravity feed and suction operation venting must be
carried out via the hole on the upper suction elbow. In the ease of suction
operation the pump must additionally be evaeuated(a vacuum must be created).
2. Running:
1 ) . As soon as the
pump starts to deliver this can be recognized by the rising gauge presstire
slowly open the delivery, gate valve fully.
2). All additional
connections for cooling, heating, lubrication irrigation or sealing liquid ete,
if fitted, must be opened fully or switched on and the flow must be checked.
3) . 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 ease temperature rising.
4) . Prolonged
operation against a closed shut- off element is not permitted in order to
prevent the medium handled from heating up.
5). At room temperatures of up to 30℃the bearing temperature should
not exceed 90℃. At higher room temperature the bearing temperature should be
below 100℃.
6) . If the pump features oil-lubricated
bearings, the correct oil level must be verified at regular.
7). If the flexible
coupling elements begin to show signs of wear, they should be replaced in clue
time.
8) . If the liquid for
sealing, cooling and lubricating is taken from an external source, the pressure
must be 1.0 to 2.0 bar higher than at the suction nozzle. The gland packing(if
the pump is fitted with one) should drip slightly during operation. The gland
should only be gently tightened.
3. Stopping
1 ). While stopping
the pump running, first turn off the brake valve on the discharge pipe passage
way.
2) . Close the auxiliary connections. The
shaft seal in pumps where the liquid is fed in under vacuum must also be
lubricated with sealing liquid during standstill.
3). In the eve.nt of
frost and/or prolonged shutdowns, the pump and if applicable the cooling
chambers must be drained or otherwise protected against freezing.
4) . Pumps handling
liquids posing health hazards must be dreeontaminated. When draining the edium
see to it that there is no risk to persons or the environment.
