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:What does electromechanical vector pump mean?
It is a close set of mechanical and microelectronic technology. It adopts dual control center mode to control, and has a new water pump with logic control center and IPC control center.
Q:What is the pumping property of concrete?
Pumpable concrete slump is generally greater than 160mm, the mortar content is too low, the maximum aggregate size of not more than 1/3 of the diameter of the pump pipe, sending process segregation, plugging in the pump.
Q:Is the sewage pump the same as the mud pump?
Two of the main performance parameters of mud displacement and pressure, displacement from a number of liters per minute, with the diameter and the drilling fluid requirements from the hole on the back end of the speed, the larger aperture, the greater the displacement. The upstream return speed of the washing fluid is required to remove the cuttings and rock powder from the drill in a timely manner from the bottom of the hole and reliably carry it to the surface. Through drilling and extraction, mud can be obtained at the bottom.Sewage pump is mainly used for industrial wastewater treatment, sewage treatment, environmental protection has played a big role. Among them, the sewage pump is also a sewage pump with cutting wheel, such sewage pump can be chopped dirt, and then extract the sewage clean.
Q:What does the pump mortar do?
Concrete pump before the need to transport water and pump pump material, dredge pipeline. In accordance with the technical specification for concrete pumping construction (JGJ/T10 - 1995), pumping concrete, pump mortar generally use cement slurry
Q:What is the nominal pressure of the hydraulic pump and hydraulic motor?
Rated flow refers to the flow under the rated speed and rated pressure input to the motor.Due to leakage loss, the actual flow of the input motor must be greater than its theoretical flow. Actual flow of motor (i.e. inlet flow) leakage flow = theoretical flow of the motor.
Q:Why is the submersible pump tripped on an electrical switch?
There should be the following reasons: 1) the setting value of the trip switch is too small, and the operating current of the submersible pump exceeds its setting value, and the switch is tripped
Q:Why does the centrifugal pump start and close first when the outlet valve is closed?
When the valve is closed off opposite is the first current to the rated current, avoid instant electricity loss of other electrical equipment caused by voltage fluctuation. At the same time, some centrifugal pump outlet check valve is not installed, the role of avoiding the pipeline caused by backflow of water pump reversal.This Regulation (or operation regulation) is generally applicable to larger power centrifugal pumps. For small power equipment, it can be used to determine whether the above operation is necessary for actual use
Q:What is the Rhodes pump?
The ultimate vacuum of roots pump depends on the pump structure and manufacturing accuracy, and also depends on the limit vacuum of the front pump. In order to increase the limit vacuum of the pump, the roots pump can be used in series. The working principle of roots pump is similar to roots blower. As the rotor continues to rotate, the gas is pumped from the intake air to the space between the rotor and the pump housing V0, and then discharged through the exhaust port. Since the V0 space is fully enclosed after inhalation, the gas in the pump cavity does not compress and expand. But when the top of the rotor turns off the edge of the exhaust and the V0 space communicates with the exhaust side, the gas pressure at the exhaust side is higher, and a part of the gas flows back into the space V0, causing a sudden increase in the gas pressure. As the rotor continues to rotate, the gas is expelled from the pump. Roots pump in the pump cavity, there are two "8" shape of the rotor perpendicular to each other on a pair of parallel axis, by a transmission ratio of 1 of a pair of gear belt movements synchronous reverse movement of each other. In the rotor, the rotor and the pump housing between the wall to maintain a certain gap, you can achieve high speed operation.
Q:Why can't the centrifugal pump pump the vacuum?
Characteristic equation of centrifugal pumpStudy the effect of fluid on centrifugal pump to obtain energy.The experimental condition of u is that the ideal fluid of unit weight bends the flow between blades at infinity.U investigated the mechanical energy balance of the fluid between the adjacent two inlet and outlet sections, that is, the relationship between theoretical pressure head and theoretical flow.
