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 is the series of pumps? What's the difference between a unipolar and a multistage?
Each impeller is of the first stage. (two impellers share only one level, and exit is only level one)
Q:Difference between pump and compressor
In the spiral case, the liquid slows down due to the gradual enlargement of the flow passage, and the part of kinetic energy is converted to static pressure, and finally flows into the exhaust pipe at higher pressure and is sent to the required place. When the liquid flows from the center of the impeller to the outer edge, a vacuum is formed at the center of the impeller. As the pressure at the upper level of the tank is greater than the pressure at the pump inlet, the liquid is continuously pressed into the impeller. Visible, as long as the impeller continues to rotate, the liquid will continue to be inhaled and discharged.The working principle of the linear pump is different from that of any other pump. It adopts the principle of magnetic suspension and the hydraulic structure of the spiral ring to realize liquid propulsion, that is, to cancel the shaft, to cancel the shaft connection, and to cancel the sealing structure of the shaft. After starting, the electric current is transformed into a magnetic field, and the magnetic field force drives the spiral ring to move, namely, the spiral ring promotes the liquid advance.Compressor (compressor), a driven fluid machine that promotes low-pressure gas as a high pressure gas, is the heart of a refrigeration system. It is of low temperature and low pressure refrigerant gas suction pipe from the suction, through the operation of the motor drives the piston to compress it after high temperature and high pressure refrigerant gas discharge pipe to the exhaust, to provide power for the refrigeration cycle, so as to realize the compression and condensation (exothermic), expansion and evaporation (endothermic) refrigeration cycle.
Q:Fire hydrant pump button, under what circumstances do not need to install?
General high voltage system, when normal, use small pump steady pressure.Fire hydrant button lifting pump is one of the multiple pumping methods, and it is an important link of reliable operation of the system.

Q:What is a gear pump for?
Gear oil pump is through a pair of parameters and the same structure of the involute gear of each other rolling meshing, the tank of low pressure oil to work can do the important parts of high pressure oil. A power unit that converts the mechanical energy of an engine into hydraulic energy. The engine is prone to the following faults during its use.
Q:What is a solution pump?
(4) smooth running, low noise, no lubrication, no lubrication and low noise due to the absence of rolling bearings and motor fans(5) a wide range of use, the high temperature, high pressure, low temperature, high melting point and other conditions are able to meet the requirements2.2 shielding pump shortcomings(1) because the shielding pump adopts sliding bearings and is lubricated by the medium to be transported, the medium with poor lubricity should not be transported by shielding pump. Generally, the viscosity of the pump medium is 0.20mPa.s.(2) the efficiency of shielding pump is usually lower than that of single end mechanical seal centrifugal pump, which is approximately equal to that of double end mechanical seal centrifugal pump(3) long time in small flow operation, shielding pump efficiency is low, will lead to heat, make the liquid evaporation, and cause the pump to dry, and thus damage the sliding bearingsCanned pumps can be divided into the following types: 1) basic type 2) reverse circulation type 3) high temperature type 4) high melting point type 5) high pressure type6) self priming 7) multi stage 8) mud type
Q:What is the principle of a turbopump?
The working conditions of the turbine are different from those of the medium used, so the structure of the turbine is varied, but the basic working principle is similar. The most important component of a turbine is a rotating element (rotor or impeller) mounted on a turbine shaft with blades uniformly arranged along the circumference. The energy of the fluid is converted into kinetic energy in the flow through the nozzle, and when the fluid passes through the rotor, the fluid impacts the blade and drives the rotor to rotate, thus driving the turbine shaft to rotate. The turbine shaft drives the other machinery directly or through the transmission mechanism, and outputs mechanical work.
Q:The water tank of the fish tank does not air out and only has the water outlet
The picture above is very clear, but I didn't say anything about it. My problem is solved. The intake pipe and the exhaust pipe are connected by the inverted T type. The intake pipe is upward, but not fixed. It can be rotated. The intake pipe can be rotated to adjust the number of bubbles
Q:Why should I pump the pump before starting the centrifugal pump?
1., if it is backward flow, it is not pumping;2., if the pump is installed underwater (such as submersible sewage pump), it is not pumping;3. pump is for installation in the form of suction. If no diversion irrigation pump, then the pump is full of air quality, air density is less than water, the pump will not be inside the gas out, the pump pressure will not be far less than the atmospheric pressure, the water will not be pressed into the pump to pump through irrigation formed inside the closed environment, the pump will start water out will cause local vacuum, entrance external water pressure into the pump is in inside and outside differential pressure, complete water movement. (vacuum water diversion is directly through the vacuum pump pumping the air in the pump, resulting in internal and external pressure difference, the external water pressure in the internal and external pressure is press into the inlet of the pump. The principle is the same as the pump. A standard atmosphere of =10m water column.)
