Q: What is the difference between swashplate pump and crankshaft pump?: In hydraulic system:Axial piston pump is the use of parallel with the transmission shaft in the plunger plunger reciprocating movement of the volume changes generated by the work. As the plunger and the plunger hole are circular parts, processing can achieve high accuracy with the high volume efficiency, stable operation, good flow uniformity, low noise, high working pressure, but the hydraulic oil pollution is more sensitive, more complicated structure, high cost.

Q: 5 floor water pressure is too low, what kind of water pump is better?: Pipe blockage, leaks, or throttling devices are not opened. This can be tested on a pipe with a pressure gauge;Water pump is equipped with power source, power or speed does not match, check the pump and power end nameplate, power end of the pump power is generally 1.1.5 times;

Q: The function of centrifugal pump: 6. Stuffing box mainly consists of packing, water seal ring, stuffing box, packing gland and water seal pipe. The function of the stuffing box is mainly to close the gap between the pump shell and the pump shaft. The water in the pump is not allowed to flow outside and the outside air is not allowed to enter the pump. Always keep the vacuum in the pump! When the pump shaft and packing friction heat, it is necessary to rely on water seal to control water into the water ring, so that the filler cooling! Keep the pump running properly. Therefore, in the water pump running inspection process, the stuffing box inspection is to pay special attention to! In the operation of about 600 hours, it is necessary to replace the packing.

Q: Is the diaphragm pump and the drain pump one?: Therefore, the need to play a liquid discharge pump, if the medium is corrosive liquid, high viscosity, volatile, flammable, highly toxic liquid, you can choose diaphragm pump. Conversely, the general liquid, there is no special requirements, you can use the general centrifugal pump to reduce costs.

Q: Why can't the inlet of centrifugal pump be negative pressure?: Therefore, the centrifugal pump inlet pressure can be negative, and negative number, should be used to pump cavitation margin and liquid saturated steam pressure parameters to specific calculation. Sometimes, the liquid saturated steam conveying pressure is very high, such as the 9 m water column, then the minimum pressure of the pump inlet should be equal to 4+9=13 meters, the atmospheric pressure is higher than 3 meters, not only for negative pressure, even higher than the atmospheric pressure to work properly.

Q: Water pump does not produce water, what are the reasons?: The reason why centrifugal pump does not produce water:1. pump inlet or sink, water tank water shortage.2. water pump pipe blocked or valve not open.

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: How can I buy a pump?: 2, must meet the characteristics of the media requirementsFor the delivery of flammable, explosive, toxic or valuable medium pump, requiring reliable sealing shaft or the use of non leakage pump, such as magnetic drive pumps (without shaft seal, using isolated magnetic indirect drive).For the transmission of corrosive medium pumps, convection components are required to use corrosion-resistant materials, such as fluorine plastic corrosion resistant pump.For conveying pumps containing solid particles, wear resistance materials shall be adopted in convection parts, and clean liquid shall be used for shaft seal when necessary.

Q: Why is the flow of the pump too small will occur cavitation phenomenon?: Throttling regulation is to change the opening of the valve to change the flow of the pump, that is to say, to change the characteristic curve of the pipeline. The commonly used to regulate the flow of exports, because the entrance throttle makes reduce the inlet pressure caused by cavitation danger.

Q: What is the difference between centrifugal pump and self suction pump? Which is better?: In order to prevent the filling liquid into the pump shell because of gravity flow in the low groove, in the pump suction pipe at the entrance of a non-return valve (valve); if the location of the pump below the liquid level in the tank, then start without irrigation pump.Self-priming pump is a self-priming centrifugal pump, centrifugal pump is a kind of.Specific choice of a pump, depending on your specific parameters and conditions of use.
