However, improper installation, long use time or poor maintenance, but also easy to wear or destroy. Rolling bearings In addition to the individual parts can be replaced with new, generally have to replace the whole parts. The mouth ring is also called a leak reduction or grinding ring. It is one of the most wear-prone parts in the pump. After wear can be repaired or replaced with new. When replacing the new leak reduction ring, its inner diameter should be configured according to the outer diameter of the impeller inlet. If the impeller inlet diameter wear, can be turning processing, in order to eliminate trench marks and ellipses, and then configure the internal diameter reduction of the leakage ring, impeller inlet diameter can generally be turning three times. Filler after a long time will harden and lose elasticity, will make the pump leakage, leakage, generally should replace the new filler. Oil seal is rubber products, easy to wear and aging, generally have to replace new parts. Parameters and properties of water pump (1) The main parameters of the pump pump parameters are the main technical data of the pump's operating performance, including flow, lift, speed, efficiency and ratio of the number of revolutions. Flow rate (Q) The flow rate of the pump refers to the amount of liquid discharged during the unit time.

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。jdhuiquan4.20

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

電動機上下兩端各有一軸承室，裝有滾動軸承和機械密封裝置。電動機外殼設有兩排進出水孔，使電動機工作時內部充滿清水，確保電動機正常運行。水泵有葉輪、泵殼、進水段組成，有離心式、混流式、軸流式三種。原材料均為鑄鐵。水泵位于電動機外伸軸上端。干式下泵型潛水電泵QX型干式下泵型潛水電泵設計新穎。外型美觀，密封可靠。電動機內裝有熱保護開關和電子自動保護器。水泵位于整機下端，故可將積水吸干。廣泛應用于灌溉和工礦企業、建筑工地的地下水道排水作業等。（1）使用條件電泵潛入水下深度為0.5～5米；水溫和環境溫度均不超過40°C；水所含固體雜質的體積比小于0.1%，PH值6.5～8；電源為50赫茲、380伏三相交流電。

二.結構和作用

故又稱斜流泵。常用的農用泵（一）離心泵離心泵型號、品種規格及其變型產品在農用泵中是最多的。根據水流入葉輪的方式、葉輪多少、泵本身能否自吸以及配力大小和動力品種等，離心泵有單級單吸離心泵、單級雙吸離心泵、多級離心泵、自吸離心泵、電動機泵和柴油機泵等。單級單級離心泵老的泵型號有BA、B型單級單吸離心泵，80年代，我國根據國際標準和排灌機械實際情況，對離心泵產品進行更新換代研制工作，并生產IB型、IQ型單級離心泵系列產品，已列為國家專業標準和行業標準。單級單吸離心泵，水由軸向單面進入葉輪，葉輪只有一個，因此稱為單級單吸離心泵。其特點是，與混流泵、軸流泵相比，揚程較高，流量較小，結構簡單，使用方便。IQ型單級單吸離心泵（又稱輕小型離心泵）是針對我國國情并滿足用戶提出結構簡單、重量輕、價格低、性能好和配套方便的要求而設計的。1.HW pump mainly has pump cover, impeller, pump body, pump shaft, bushing, and bearing body and other major components. The pump cover is connected with the pump body and the inlet pipe respectively. 2. There should be an appropriate gap between the pump cover plane and the impeller plane. The gap is too small will produce friction, the gap is too large, will lead to the pump body pressure water a large number of reflux, is the pump efficiency reduction. The suitable gap used in practice is 0.3-0.7mm, and the gap can be adjusted by adding and subtracting the thickness of the paper pad.

3. The shaft is applied to protect the pump shaft and should be replaced in time after wear.

1. Screw holes at the upper end of the pump body, used for filling water diversion or connecting vacuum pump pumping gas to divert water. 

2. In order to expand the scope of application of the pump to meet the different needs of users, can cut the outer diameter of the impeller or exchange different performance of the impeller.
