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.

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(shè)有兩排進出水孔，使電動機工作時內(nèi)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(shè)計新穎。外型美觀，密封可靠。電動機內(nèi)裝有熱保護開關(guān)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(yīng)用于灌溉和工礦企業(yè)、建筑工地的地下水道排水作業(yè)等。（1）使用條件電泵潛入水下深度為0.5～5米；水溫和環(huán)境溫度均不超過40°C；水所含固體雜質(zhì)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。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.
