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:How to select hydraulic pump?
Select the hydraulic pump from the following considerations:1. hydraulic pump pressureHydraulic pump operating pressure is the pump (or motor) in actual work output (or input) oil pressure, determined by the external load.Rated pressure refers to the maximum pressure under continuous running in accordance with the test standards under normal working conditions. The size of the pump is limited by the service life, and the service life of the pump (or motor) will be shorter than the design life if it exceeds the rated pressure. When the work pressure is greater than the rated pressure, it is called overload.
Q:Suction stroke and lift of water pump
For example: there is a kind of water pump, the model is called "BSP" series, the volume is not large, but the nominal suction process can be 4 meters, it can not add water to 4 meters, it is considered to be relatively high in the micro pumpIn micro pumps, not all pumps have self-priming capacity ("suction stroke")Some centrifugal pumps there is no self-priming ability to use must first do add water. Although some micro pump with self absorption capacity, but "suction" are often the subject of "and the water inlet pipe in all air, can smoke the vertical height of water gap, even only half not so. The pump selection, the absorption process is a relatively important parameter.
Q:How to select metering pump head?
When it comes to metering pump heads, the usual problem is when they measure acid, chlorine, fluoride, and hydrogen peroxide. Due to the difference in concentration and operating temperature, it is difficult to determine the specific pump head material.
Q:Why does the centrifugal pump start with a closed valve and the axial pump starts with an opening valve?
Because the characteristic curves of the two are different.The power of centrifugal pump decreases with the decrease of flow rate. When the flow rate is zero, the power is minimum, so the centrifugal pump is started with a closed valve.
Q:How is the pump level of submersible sewage pump determined?
Pump water level must be higher than the water pump top, so that the motor running in the lower water temperature cooling environment, otherwise long-term operation will burn the machine
Q:What is the pump, how to classify, mainly used in where?
Classification of pumpsAccording to the principle of division:1. displacement pumpDepending on the movement of the work parts, the volume of the work increases periodically and reduces the suction and discharge of the liquid, and the pressure of the liquid increases directly by the extrusion of the working partsAccording to the different movement of moving parts, it can be divided into two types: reciprocating pump and rotary pumpAccording to the structure of the moving parts are different: piston pump and piston pump; there are gear pumps, screw pumps, vane pumps and water ring pump
Q:Is the vacuum pump air compressor?
A vacuum pump is a device or device that uses a mechanical, physical, chemical, or physical chemical method to pump a vacuum from a container to be evacuated. Generally speaking, a vacuum pump is a device that uses various methods to improve, produce, and maintain a vacuum in a confined space.
Q:Household automatic booster pump, how much pressure can you work automatically?
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
Q:Why can't the centrifugal pump pump the vacuum?
Running process: depending on the centrifugal pressure of the liquid in the impeller, the liquid is sucked into the liquid, and the liquid in the pump shell has the conversion of the energy form, so that the fluid can obtain the mechanical energy mainly with the static pressure.The characteristics of the system: the suction diameter than out of large diameter, the general valve installed.
