Q: Must the water pump in the tank be all soaked in water?: Need a submersible pump in the water, but it is not entirely like this, I have to work for a long time no problem in water, but there is a problem you should pay attention to the water pump, at least in half, or stop when the smoke is not on water.

Q: What is cavitation, centrifugal pump cavitation phenomenon how to solve?: In order to make the pump full of liquid, usually in the valve installed at the bottom of the filter screen along the suction pipe, the valve until the end against the valve, strainer prevents the solid material into the normal operation of the pump impeller damage or hinder the pump.

Q: If you use an ordinary 15W submersible pump, put it in the tank, if the leakage, the fish will hang it?: What will happen then? The aquarium glass is an insulator. The water in the fish tank has the same potential as the live wire, and the fish is like a bird standing on the fire line. No electricity flows through their bodies, so they won't get electrocuted. But if you put your hands into the water, you will get an electric shock, because the line voltage through the water, then your body and the earth to form a loop, current flowing through your body you will get (of course, if you stand on the insulator does not get an electric shock)

Q: What is the relationship between the minimum suction vacuum of a pump and the required cavitation?: Suction is allowed to pump the vacuum from the distance from the inlet, which is part of the field installation.The manufacturer of cavitation allowance is closely related to the design and process of pump. Estimation formula: cavitation allowance =10.33 meters - allow suction of -0.5 meters (safety).

Q: Why should I pump the pump before starting the centrifugal pump?: Before the operation of the centrifugal pump, the pump must be filled with water, exhaust the air, before you start the operation. All centrifugal pumps should be handled this way, which is the centrifugal pump itself.The way of water diversion:1., in the centrifugal pump outlet increase water diversion pump (usually using vacuum pump), start the centrifugal pump before, start the vacuum pump, the centrifugal pump air into;2. increase the vacuum water tank before the intake of the centrifugal pump to meet the working conditions of the centrifugal pump;3. in the centrifugal pump inlet water increase valve, to meet the working conditions of centrifugal pump;4., if the water tank or water tank volume of water level is higher than the centrifugal pump position, the first operation of the front row empty, usually do not empty, you can use.

Q: Is the centrifugal pump large or small?: When the liquid is lowered at a certain temperature to the vapor pressure at this temperature, the liquid bubbles. The phenomenon of producing bubbles is called cavitation. When the bubbles are flowing to the high pressure, the volume of the bubbles is reduced so that they are destroyed. This due to the pressure of rising bubbles disappear in the liquid in the phenomenon called cavitation bubble collapse. The local pump is in operation if the over-current part (usually the impeller blade inlet somewhere later) for some reason, the absolute pressure of pumping the liquid was reduced to liquid vapor pressure temperature, liquid vaporization began there, produce a lot of steam bubble formation, when the liquid contains a lot of bubbles by forward high pressure impeller Zone, high pressure liquid around the bubbles in the bubble decreases drastically and rupture. Condensation in the bubble burst and the liquid particle at high speed to fill a hole in this moment has a very strong effect of water hammer and the impact of high frequency against the metal surface, the impact stress of hundreds to thousands of atmospheric pressure, impact frequency can be up to tens of thousands of times per second, serious breakdown when the wall thickness will be. The process of cavitation in a pump is caused by the bursting of bubbles and bubbles in the water pump and the destruction of the over-current components. Water pump cavitation, in addition to the over-current components will have a destructive effect, but also produce noise and vibration, and lead to the performance of the pump down, seriously when the pump will be interrupted liquid, can not work properly.

Q: What are the main performance parameters of hydraulic pumps?: Displacement and flowDisplacement refers to the pump (or motor) every turn a week, by the size of the sealing chamber geometry variable discharge (or enter) the volume of liquid, commonly used unit is ml/r (ml / rev). Displacement can be changed as a variable pump (or variable motor), and the displacement can not be changed into a quantitative pump (or a quantitative motor).Actual flow is the amount of flow at the outlet (or inlet) when the pump (or motor) is operating. As the pump itself leaks, the actual flow is less than the theoretical flow. As the motor itself has an internal leakage, to achieve the specified speed, in order to compensate the leakage, the actual flow of input must be greater than the theoretical flow.

Q: How many pumps does the 80cm tank use?: Filter pump to select the water per hour can be filtered more than 3 times, I personally feel that this is almost enough. Of course, the more times the better, but also consider that if the pump is too large, the water inside the tank will be too large.128X3=384LThat is, the flow must be more than 384L/H of the water pump.You can buy a bigger pump, because the pump for a long time there will be some attenuation and domestic things in general to sign data, so it should be based on your actual situation to buy. Taobao on this category is about 20~40 yuan.

Q: How to maintain and repair the booster pump of pipeline pump?: I. installationAssembly and disassembly1. scrub all the spare parts to be cleaned.2. mechanical seals are installed on the main shaft of the motor, and a small amount of clean turbine oil or 20 oil is added to the surface of the mechanical seal.

Q: Attention should be paid to the use of pumps?: 7 water pump and pipe interface must be sealed, because if there is debris access, then the pump will cause damage to the interior. 8 for the water pump bearing is also the focus of inspection, use up to check whether the bearings wear,
