Q:Concrete pump 125 pipe wall thickness

Concrete pump, also called concrete pump, consists of pump body and pipe. The utility model relates to a machine for continuously conveying concrete along a pipeline by utilizing pressure, which is mainly used for building, bridges and tunnels

Q:The function of centrifugal pump

4, bearings are set on the pump shaft supporting the pump shaft components, there are two kinds of rolling bearings and sliding bearings. Rolling bearings use butter as a lubricant, refueling should be appropriate, generally 2/3 ~ 3/4 of the volume is too much, will heat, too little, there is noise and fever! The plain bearings are made of transparent oil as a lubricant and fill up to the oil level. Too much oil will leak out along the pump shaft and float *, too little, the bearings will overheat and burn out, causing accidents! In the pump running process, bearing temperature is highest in 85 degrees, generally run at about 60 degrees, if higher, will find the reason (whether there is impurities, whether the oil is black, whether water) and timely processing!

Q:What does electromechanical vector pump mean?

Scope of application is;Residents living water: such as high-rise buildings, residential areas, villas and so onPublic places such as hospitals, schools, gymnasiums, golf courses, airports, etc

Q:How to install, operate and maintain the pipeline booster pump?

Should be "People's Republic of China network security law" requirements, since June 1, 2017, the use of Internet services to carry out real name authentication account. In order to ensure your Baidu account can be used normally, please check the account number as soon as possible. Thank you for your understanding and support.How to install, operate and maintain the pipeline booster pump?Brother Yao s Gc76 2547 | browseRecommended for 2016-12-01 23:52:54 best answerThe installation of booster pump must be installed horizontally or vertically according to the installation method. The direction of flow shall be consistent with the arrow on the pump body, and installed as far away from the water level as possible. A valve shall be installed on the pump inlet line for ease of use and maintenance. When the impeller is the aspiration level below the pump on the pump shaft end or around the pump should be installed check valve, the outlet is connected with 13 links for water use, at first use to pump should be filled with water, and tighten the screw plug. The pipe connection should be tight, especially the water inlet pipe can not leak, otherwise it will reduce the pump head or not pumping water. The pump cavity is not water, not a long time running, so as not to damage the seal

Q:The water tank of the fish tank does not air out and only has the water outlet

The water pump is cut off, the intake pipe is drawn out, and the water in the air pipe is blown out, then the water pump is put on the surface of the water, and the air inlet pipe is inserted on the surface of the water pipe, and then the water pump is put back into the water, and the water pump is electrified. Try again several times at a time. It should be effective.

Q:What's the meaning of the pump head in the water pump, please advise, thank you

The pump head of the centrifugal pump refers to the shell that contains the impeller and impeller, and also includes the shaft part that drives the impeller. It can be used as the part of the motor and shaft coupling and the base.

Q:Know flow and lift how to calculate the pump power?

The pump power (kw) ={9.61* flow (cubic meters per second) * head (m)}/.Where ETA is device efficiency, including mechanical, electrical loss and other factors, generally between 55%~80%. The smaller the pump, the lower the efficiency.

Q:What's the difference between a concrete pump and a concrete pump truck?

Concrete pump and concrete pump truck are concrete conveying machinery, use the same, but the former need to transport and car towing need additional support pipeline, the locomotive body and arm extends freely, without pipeline, hundreds of thousands of millions of the former, the latter

Q:What is a positive displacement pump? He Weizheng displacement?

The principle and structure of positive displacement pumps are similar to those of hydraulic motors. Positive displacement is the pump outward to provide flow and pressure, that is, conventional pumps. A negative displacement pump is a hydraulic motor that rotates by external pressure and flow.

Q:Household automatic booster pump, how much pressure to work automatically, the water pressure and how many kilograms?

With the pressure does not matter, because the pressure is small, it is necessary to boost the pump, the water pressure with the pipe flow and the size of the booster pump related
