常常是軸承發熱比較普遍的原因，如滾動軸承保持架損壞，鋼球壓碎內圈或外圈斷裂，滑動軸承的合金層剝落，掉塊等。這種情況軸承處聲音異常，噪音大，應及時拆開軸承檢查并更換之。水泵轉子的靜平衡不好。水泵轉子徑向力增大，軸承負荷增加，造成軸承發熱。水泵軸彎曲或不同心，會使水泵振動，引起軸承發熱或磨損。通過以上的分析，如果你還不能解決混流泵在使用過程中軸承溫度過高的問題，可以隨時致電我們。????。安裝的是否牢靠關系到后期使用中性能的穩定與否，所以一定要做好混流泵的安裝工作。銘科泵業在長期的安裝調試中得出一些經驗，今天就給大家做個分享。按混流泵出水室的不同，混流泵有蝸殼式和導葉式兩種類型。蝸殼式混混流泵作為泵站的重要組成。

一.概述

1.用途：HW混流泵為臥式，單級，單吸，渦殼式混流泵。適用于輸送清水或物理，化學性質類似于水的其它液體。被輸送液體溫度不宜高于50度。廣泛用于農田灌溉，工業和城市排水等多種場合。HW泵的性能范圍：流量90-9000m3/h    揚程3.5-22m。

2. 特點：結構簡單，使用可靠，裝修方便，而且效率高，體型小，重量輕。jdhuiquan4.9

3. 傳動方式：用直接傳動和變速傳動。常用動力機是電動機和柴油機。訂貨   時應明確動力機的型號，以便確定聯軸器和皮帶輪的型號

4.型號說明：以150HW-8S例

         150---------泵進出口直徑mm

          8------------設計揚程 m

         S------------變型代號

The coupling pair is too bad or the axial gap is too small. Workaround: View the condition in the alignment and adjust the axial voids. Shaft seal heating elements and treatment methods are as follows: 1, the filler pressure is too tight or dry. Treatment: Relax the filler, check the water seal tube. The water seal ring is misplaced with the water seal pipe. Workaround: View the alignment from the beginning. Scour, poor cooling. Treatment: View scour cooling circulating tube. There is something wrong with the mechanical seal. Treatment: View mechanical seals. The main elements of rotor movement and treatment methods are as follows: 1, the operation is not appropriate, operating conditions away from the pump planning conditions. Treatment method: Strict operation, so that the pump has been in the planning of operating conditions adjacent to the operation. Balance is not recombination. Treatment method: Dredge the balance tube. Balance plate and balance plate material is not requested. Treatment: Replace the raw material to meet the requested balance plate and balance disk seat. 11, the occurrence of water hammer elements and treatment methods are as follows: 1, because of the power outage in Russia, the formation of system pressure fluctuations, showing the presence of gas in the platoon. Treatment: Drain the gas.

二.結構和作用

1.HW型泵主要有泵蓋，葉輪，泵體，泵軸，軸套，及軸承體等主要零件組成。 泵蓋分別與泵體和進水管相接。2.泵蓋平面與葉輪平面之間應有適當間隙。間隙過小會產生摩擦，間隙過大，會導致泵體內的壓力水大量回流，是泵的效率降低。實際使用的適宜間隙為0.3-0.7mm，間隙可用增減紙墊厚度來調整。

3.軸套用以保護泵軸，磨損后應及時更換。

1.泵體上端的螺孔，用于加灌引水或連接真空泵抽氣引水。 

2.為擴大泵的適用范圍，滿足用戶不同需求，可切割葉輪外徑或換用不同性能的葉輪。

The relevant parts may be replaced as appropriate to troubleshoot. And if the pump damage is very serious, there is no repair conditions on the way, you can put the pump into, outlet pipe directly on, in order to make full use of the natural circulation of hot and cold water temporarily so that the engine to maintain a normal temperature; or use an inner tube or bucket as a container to secure it firmly, and then draw two hoses from the container, One is connected to the inlet of the engine and the other to the outlet of the engine, and the other end of the two tubes is inserted into the container. Secondly, the hose should be fixed firmly. If only the pump shell produces cracks and leaks, the cracks can be treated clean, and then glued with adhesives. For emergency use, egg cleaning and cement can be mixed into sticky groups applied to the cracks, after a few minutes of solidification can be used. Also, the construction machinery driving or operation process, the water seal leakage of the pump is also a common thing. As long as there is no damage to the hydrosphere or swelling deformation, the spring force of the water seal is insufficient or broken and other faults.
