Q:Why can't the inlet of centrifugal pump be negative pressure?
However, the centrifugal pump will have its import pressure requirements, which is to prevent cavitation, that is, the fear of the delivery of liquid at low pressure will occur gasification. Centrifugal pump has an important parameter called NPSH, for example relating to the inlet pressure, the pump NPSH, 4 meters, it means that the absolute pressure of imports should be higher than the saturated steam conveying fluid pressure of liquid column is 4 meters high, so, when it is at a temperature of saturated vapor pressure for water transport 2 meters, 4+2=6 meters minimum inlet absolute pressure. Because the absolute pressure is 10 meters water column atmospheric pressure, at this time the entrance negative pressure is 10-6 meters =4 meters water column.
Q:What should be used to pay attention to the use of mechanical pumps?
Overall: large pump should first do a good job of the foundation, to find a good whole, fixed, and motor, pump should be added good oil, the first test of the motor, and then conjoined test
Q:Advantages and disadvantages of canned pumps
The ordinary centrifugal pump is driven by coupling the pump impeller shaft is connected with the motor shaft, the impeller and the motor rotates while working and shielding pump is a kind of non seal pumps, pump and motor is sealed in a medium filled by pumping the pressure vessel, the pressure vessel only static seal and, by a group of wires to provide a rotating magnetic field and rotor drive. The structure eliminates the rotary shaft sealing device of the traditional centrifugal pump, so the utility model can be completely free from leakage.
Q:What's the submersible pump?What is a submersible pump, and what about it?
Submersible pump is a pump directly on the water inside the pump, eliminating the water inlet pipe, eliminating the trouble of ordinary water, is very convenient, just a pool, pool, bucket, water tank water level is shallow to be able to work, meet your requirements of pumping drainage
Q:What are the problems that should be paid attention to when using vacuum pumps?
(1) check the vacuum pump line and the joint site regularly to see if there is any looseness. Turn the vacuum pump by hand and see if the vacuum pump is flexible.(2) add lubricating oil to the bearing body, observe the oil level at the center line of the oil mark, and the lubricant shall be replaced or supplemented in time.(3) plug screw vacuum pump of the water screw, filling water (or lead paste). (4) turn off the gate valve of the water outlet pipe and the outlet pressure gauge and the vacuum gauge. (5) point motor, and see if motor steering is correct.(6) start the motor. When the vacuum pump is in normal operation, open the outlet pressure gauge and the inlet vacuum pump. As soon as the proper pressure is shown, the gate valve is gradually opened, and the motor load is checked.
Q:Working principle and diagram of axial piston pump with pressure compensation variable
Working principleThe main part (see section structure) the transmission shaft drives the rotating cylinder, the plunger seven uniform distribution on the cylinder to rotate around the shaft center line through the center of the spring will be slippery boots column components in the variable pressure in the head (or swash plate). In this way, with the rotation of the plunger cylinder for reciprocating motion complete, oil absorption and oil pressure action.
Q:If you use an ordinary 15W submersible pump, put it in the tank, if the leakage, the fish will hang it?
Submersible pump even if it really leakage, it will not cause the fish electric shock. The so-called leakage is the submersible pump wire or shell broken, live parts and water contact, the most extreme test is a fire line directly into the fish tank
Q:What are the parts of a pump? How do you classify it?I just want to know
The liquid ring pump: pumping air, the working medium is generally at room temperature water gas lift pump: simple structure of submersible sewage pump: a form of basic principle, performance parameters of centrifugal pump, with it the same. Underwater installation, sound, water cooling condition, screw pump: spiral lower invasion water medium variety formThere are too many kinds of pumps, such as submersible pumps for wells, centrifugal feed pumps, sewage pumps, etc. the submersible pumps are wet, oil immersed, etc.The water pump for automobiles is divided into oil lubrication and grease lubrication,
Q:What are the failures and causes of the replacement of the fuel pump assembly?
Gasoline pump is the gasoline from the gasoline tank suction and the gasoline tank has a certain pressure, thereby, it overcome the resistance of the pipeline, pipeline and fuel filter into the carburetor float chamber or electronically controlled injection engine in the guide frame.
Q:What does centrifugal pump mean horizontally?
In other words, pump casing and pump body along the horizontal center of the pump leaves into the upper and lower halves, so that when the pump leaves the pump cover open, you can pump and bearings as a whole pumping out. No need to remove the pipe. I don't know. Do you understand?.
