Definition of water pump
Answer: In terms of the manufacturing principle and process of water pumps, there is no definition of water pumps. However, in terms of water supply and drainage and environmental engineering, the water pump is a water pump used for the supply of clean water, and is generally placed in the clean water pool after sewage treatment or tap water purification. Horizontal single-stage centrifugal pumps are mostly used.
Rust on the water pump
Answer: Rust is possible, but it is not necessarily the rust of the water pump. Small water pressure pipes are easy to scale and rust, and are flushed out after pressurization. The power of the pump should be about 100 watts, but the lift is what matters. If your floor is high and the lift is not enough, the water will not come up. When you buy it, pay attention to it. It is best to buy one with automatic control. As long as the faucet is turned on, the pump will automatically turn on, and it will automatically stop when it is turned off. It is very convenient to use.
The difference between water pump and centrifugal pump
Answer: The water pump mainly conveys water, etc. The concept of centrifugal pump and water pump is not the same category, one is the difference between the medium and the other is the structure. Some centrifugal pumps are also water pumps. The difference is that they belong to a subordinate relationship. Water pumps belong to the classification of centrifugal pumps. The rotation of the pump shaft makes the medium do centrifugal motion in the impeller, so as to achieve the purpose of pumping! The water pump is only a small subcategory of the centrifugal pump
The process of installing and debugging the water pump
Answer: a. The sealed cavity should be kept full of liquid before starting. When conveying solidified media, the sealed cavity should be heated with steam to melt the media. The crank must be cranked before starting to prevent the soft ring from breaking due to sudden start. b. For the mechanical seal using the oil sealing system outside the pump, the oil sealing system should be started first. Finally stop the oil sealing system after parking. c. After the hot oil pump is out of operation, the cooling water in the oil seal cavity and the end face seal cannot be stopped immediately. The cooling water can only be stopped when the oil temperature at the end face seal drops below 80 degrees to avoid damage to the sealing parts.
Operation of the water pump
Answer: a. If there is slight leakage after the centrifugal pump is started, it should be observed for a period of time. If the leakage is still not reduced after continuous operation for 4 hours, the pump should be stopped for inspection. b. The operating pressure of the pump should be stable, and the pressure fluctuation should not be greater than 1 kg/cm2. c. During the operation of the pump, the phenomenon of evacuation should be avoided to avoid dry friction of the sealing surface and seal damage. d. The sealing condition should be checked frequently. During operation, when the leakage exceeds the standard, the heavy oil is not more than 5 drops/min, and the light oil is not more than 10/min. If there is no improvement trend within 2-3 days, the pump should be stopped and the sealing device should be checked.
