Q:Types and differences of pumps
Classification and working principle of pump by structureClassification of pumpsInvolved pump standard product types are also very much, a centrifugal pump, metering pump, screw pump, reciprocating pump, hydraulic pump, submersible pump, oil pump, water pump, pressure test pump, vortex pump, cryogenic pump, vacuum pump, roots pump, molecular pump, gear pump, mud pump, corrosion-resistant pump deep well pump, water pump, mixed flow pump, axial flow pump, boiler feedwater pump, liquid pump, injection pump, chemical pump, pump plugging and no leakage pump, plastic pump, fire pump and so on, there are many. Its name is divided according to some conventional classification methods such as pump vane pump volume, pump etc., some are divided by purpose such as sewage pump, pump and other health, some names are more random as diffusion pump, liquid nitrogen pump. As long as the production of this product, with standard requirements, through a certain application and approval procedures may produce a new The standard, but sometimes the content also has a repeated cross, quite. The domestic and foreign standards, the domestic standard is more than the number of foreign standards. In general, such as centrifugal pumps are widely used, the production history of the pump more standard (total standard centrifugal pump up to more than 100). As new standard pump leakage pump this rapid development is relatively small. This paper introduces the structure and working principle of the pump according to the classification of the
Q:Why can't the inlet of centrifugal pump be negative pressure?
Can be negative pressure ah, the negative pressure here refers to the pressure is less than the atmospheric pressure, but the pressure can not be too low, to prevent water vapor below the saturated vapor pressure, so that water vaporization, cavitation phenomenon, the centrifugal pump will be considered.
Q:What does electromechanical vector pump mean?
Commercial buildings: hotels, office buildings, department stores, large saunas, etc.Irrigation: such as parks, playgrounds, orchards, farms, etc.Manufacturing: such as manufacturing, washing equipment, food industry, factories and so on
Q:Troubleshooting of diaphragm pump
In the application of the pump, these conditions are likely to encounter. Each situation can be divided into several possible reasons. This guide lists the causes of failures and gives appropriate corrective maintenance measures. The meaning of all the specific terms in the guide is listed later.Air valves - copper or stainless steel valves are bolted to the center of the pump by four bolts.The piston aluminum cylinder is enclosed in the air valve to control the gas flow.Cavitation - because the pump inlet for the amount of fluid to reduce or lack, the pump discharge is less than the amount of quantitative. In fact, the fluid chamber is full of fluid before it is discharged.Static pressure drop - the inlet pressure from the pump centerline to the free point - the inlet is measured in pounds, including the specific gravity and velocity of the fluid.
Q:Why should the pump be closed when the centrifugal pump is started?
Centrifugal pump has an important characteristic: when the pressure (head) is very low, the flow will be great, which can be seen from the characteristics of the pump curve. While the pump power is directly proportional to the flow rate, pump start, no pressure in the pipeline, caused by the pump flow, high power pump, and the pump motor, the rotating part from rest to high-speed operation, need a lot of acceleration, it will cause a great starting current
Q:What's the difference between a centrifugal pump and a centrifugal pump? What are they used for?
Centrifuges are generally used to classify liquids of different densities in liquids.
Q:What is double hydraulic pump?
[double hydraulic pump] the same drive shaft drives the rotation of two pumps, which are connected together and driven by an electric motor. The suction port of the pump is common, and the oil pressure port is separated from each other. Pump output of two shares of flow can be used alone, can also be used in parallel. This pump, a pump can play the function of two pumps. For example, there are two pumps on the loader, a pump acting as the work, a pump acting as the steering, and the double linked pump can replace the functions of the two pumps. It works by coupling the two pumps at the same time.
Q:What is the dry running protector of screw pump? What's the principle and function? Thank you
The utility model relates to a screw pump dry running protector, which is used for protecting the stator and the rotor of the screw pump from being transported by air
Q:What are the basic technical parameters of the pump?
The effective power of pump and output power, with Pe said. It is the effective energy per unit time from the pump in conveying out liquid obtained in the pump. Because the lift refers to the effective energy, pump output unit of heavy liquid obtained from the pump so that the product of head and the mass flow rate and the acceleration of gravity. Is to obtain the output from the pump in unit time of liquid effective energy - efficient pump power: Pe= P gQH (W) = QH (W) - P - density of liquid pumping (kg/m3); severe gamma - pump for transporting liquid (N/m3) - Q (pump flow; m3/s; H) - pump head (m); G (m/s2). The acceleration of gravity P axle power and effective power Pe is the difference of power loss in the pump, the size of the pump efficiency to measure the efficiency of the pump. As the effective power and shaft power ratio, with ETA said. Selection of related pumps:
Q:Why is the sewage pump device coupler?
2. automatic coupling device of the sewage pump coupling device has compact structure and small occupation area. Because the sewage pump is submerged, it can be installed directly in the sewage tank, and no special pump room is needed to install the pump and pump. It can save a lot of land and infrastructure costs.
