Q: Working principle and diagram of axial piston pump with pressure compensation variable: Adjust the flow characteristics, the first limit screw to the top, according to the flow and pressure changes in the required range, adjusting the spring set, the initial flow pressure began to change to meet the requirements, then the limit screw to the ultimate pressure when the flow is no longer changed, the relationship between flow and pressure the changes are determined by the pump itself.

Q: Why can the centrifugal pump hold down the pressure?: Centrifugal pumps are vertical, horizontal, single-stage, multi-stage, single suction, double suction, self suction and other forms. Vertical centrifugal pump is referred to as submerged pump, molten salt pump and submerged pump. Centrifugal pumps use the impeller to rotate and cause centrifugal motion of the water to work.

Q: What is the displacement of the pump? Flow? What is the volume efficiency and mechanical efficiency of the pump?: Displacement of a pump: the volume of the discharged liquid calculated by the change in the size of the sealing geometry for each revolution of the hydraulic pump

Q: What is a positive displacement pump? He Weizheng displacement?: And includes a pump chamber (24) to open and a channel is arranged between the entrance and the pump chamber (26) in the second one-way valve (15), and one for the continuous displacement member (13) in the pump shell (10) in the travel section (S) actuating mechanism reciprocating motion.

Q: What is the function of a submersible pump?Do you have any knowledge about submersible pumps?.: Submersible pumpThe submersible pump is composed of a control cabinet, submersible cables, water pipes, submersible pumps and submersible motors.Submersible pump main application and scope of applicationIncluding mine rescue, construction, drainage, agricultural irrigation and drainage, industrial water recycling, urban and rural residents cited water supply, and even rescue, disaster relief and so on.Classification of submersible pumpsAs far as media is concerned, submersible pumps can be broadly divided into three categories: clean water submersible pumps, sewage submersible pumps, sea water submersible pumps (corrosive).

Q: How high can the pneumatic diaphragm pump be?: If the pump material made of polypropylene (PP) material, corrosion resistance, good chemical resistance using PP material produced by pneumatic diaphragm pump can resist medium low cost, good generality, polypropylene material mainly is especially suitable for general acid-base liquid, using poly propylene made of plastic gas diaphragm pump can only withstand the highest temperature to 65 degrees, more than this number of polypropylene plastic deformation.

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?: 3 、 mechanical requirements of high reliability, low noise, vibration.4, the correct calculation of pump procurement costs, the pump manufacturer to inspect, requiring good quality equipment, good after-sales service, spare parts can be timely supply.The micro pump and the motive of the mechanical energy or other external energy transmitted to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids.The technical parameters of pump performance include flow, suction, lift, shaft power, water power, efficiency and so on.

Q: The working principle of magnetic pump: Magnetic pumpBy the pump magnetic pump, magnetic actuators, motors of three parts. The key components of magnetic actuator by the external magnetic rotor sleeve, inner magnetic rotor and non magnetic components. When the motor drives the outer magnetic rotor, the magnetic field can penetrate the air gap and non-magnetic material, driven by the inner magnetic rotor is connected with the impeller for synchronization the rotation, to achieve non-contact power transmission, the dynamic seal into static seal. As the shaft, the rotor is within a magnetic pump, isolated sets of completely closed to completely solve the problem of "run, run, drip, leak, remove the oil refining chemical industry flammable, explosive, toxic and harmful media through the pump seal leakage security risks, effectively ensure the health and safety of workers.

Q: Types and differences of pumps: Depending on the flow of the fluid, they can be subdivided into the following:Classified centrifugal axial flow type mixed flow tubular flow typeThe basic principle of impeller centrifugal force generated by the high-speed rotation of the fluid energy rotary vane extrusion propulsion of the fluid increases the pressure to get the energy mix and energy principle of centrifugal and axial and centrifugalSuch as: central air conditioning centrifugal fan, central air conditioning or cold storage axial flow water pump, mixed flow water pump, domestic air conditioner, indoor fanWorking principle of pump and fanI. the working principle of centrifugal pumps and fansThe centrifugal force generated by the high-speed rotation of the impeller fluid power, namely fluid through the impeller, pressure and kinetic energy can be improved, which can be transported to the height or distance. The impeller is arranged in a spiral shell, when the impeller rotates, the fluid axial inflow, and then turn 90 degrees into the impeller and the radial outflow impeller. Continuous rotation of the impeller inlet in the form of vacuum, so that the fluid continuously by the pump suction and discharge.
