There are diversified forms：Such as two kinds of submersible type and dry type, current most common submersible type is QW type submerged sewage pumps, most common dry type
Sewage pump two kinds of such as horizontal sewage pump of W types and WL types vertical sump pump.Mainly for delivery of municipal sewage, contain in excrement or liquid
There is fiber.The medium of the solid particles such as paper scrap, the temperature for being typically transported medium are not more than 80 DEG C.Due in transported medium
Fibre object containing easy winding or pack.Therefore this kind pump runner is easy to block, pump can make pump cisco unity malfunction once being blocked,
Motor even is burnt, so as to cause blowdown not smooth.Serious influence is brought to urban life and environmental protection.Therefore, anti-blocking and can
It is an important factor for sewage pump is good and bad by property.
Hydraulic chamber is located at the core position of sewage pump, cooperates with impeller and completes water suction and draining, but in pump machine work
Many problems, such as cavitation are often run into when making；Pump occurs cavitation and shows when suction vacuum is more than permissible suction head
As.When drop of pressure is to by liquor charging body saturated vapor pressure at the working temperature at impeller eye, part will occur for liquid
Vaporization, the bubble of generation will enter higher-pressure region with liquid from low-pressure area, and in higher-pressure region, bubble can drastically be shunk, condensation, around it
Liquid Primordial Qi bubble rushed at high speed taken up space, produce the shock wave of high intensity, impact impeller and pump case, make an uproar
Sound causes vibrations.Chemical attack due to being subject to trace dissolved oxygen in impact force repeated action and liquid for a long time acts on, impeller
There is spot and crackle even into spongy damage in local surfaces.
Utility model content
It is to be solved in the utility model be in the prior art sewage pump serious cavitation erosion the problem of, there is provided sewage pump intermediary type
Anti scuffing hydraulic chamber, shunting increase space so as to reduce cavitation phenomenons by way of reducing pressure.
The utility model is achieved through the following technical solutions：
