Germany Kaysen imported chemical pump overview
The chemical pump is a kind of energy-saving pump. The performance and technical requirements of the pump are designed according to the performance and size specified in the international standard ISO2858. The chemical pump is a single-stage single-suction (axial suction) corrosion-resistant centrifugal pump for transportation. Solid chemical, liquid chemical pump with corrosive and viscosity-like water classification: stainless steel chemical pump, plastic chemical pump, fluorine plastic chemical pump, electric chemical pump, pneumatic chemical pump.
Negative pressure pump
The suction tube and pump must be filled with liquid before the pump is turned on. After the pump is turned on, the impeller rotates at a high speed, and the liquid rotates with the blade. Under the action of the centrifugal force, it flies outward from the impeller, and the liquid that is ejected in the pump chamber diffuses slowly, the pressure gradually increases, and then the pump At the exit, the discharge pipe flows out. At this time, at the center of the blade, the liquid is drawn to the surroundings to form a vacuum low-pressure zone with neither air nor liquid. The liquid in the liquid pool flows into the pump through the suction pipe under the action of the atmospheric pressure of the pool surface, and the liquid is continuously continuous. It is continuously sucked from the liquid pool and continuously flows out from the discharge pipe.
Positive pressure pump
Mainly refers to the working principle of the submerged pump. The submersible pump and the long shaft submerged pump are used as an example. The submersible pump immerses the motor and the pump together in the bottom of the tank. The motor drives the impeller to push the medium to the ground target, and the long shaft liquid The pump connects the pump and the motor separately with a long shaft. The working principle is that the medium is transported under positive pressure, thus solving the problem of air resistance generated by the negative pressure conveying medium and the cavitation problem of the impeller. The motor of the submersible pump is not on the liquid surface, but under the liquid surface. The motor is a submersible motor and is connected to the pump wheel into a potential liquid. The main advantage of this design is that the bearing of the pump is only a few hundred millimeters, there is no long axis, there is no swing problem, the operation is stable, the sound is very small, almost no abrasion.
The chemical pump seal forms mainly include: oil seal seal, gasket seal, thread seal, labyrinth seal, packing seal and dynamic seal, mechanical seal.
The utility model relates to a self-tightening lip seal, which has the advantages of simple structure, small size, low cost, convenient maintenance and small resistance torque, which can prevent medium leakage, prevent external dust and other harmful substances from invading, and has wear resistance. A certain compensation capacity, but not high pressure, so it is generally used in chemical pumps on low pressure occasions.
The gasket is the basic component of the centrifugal pump static seal and is used in a wide range of applications. The selection of gaskets is mainly determined by factors such as the transport medium, temperature, pressure and corrosivity of the chemical pump.
There are generally two forms on chemical pumps, one is a threaded joint gasket seal, and the other is a threaded and filled seal, both of which are used for sealing of small diameter threaded joints. The seal of the threaded electric diaphragm pump gasket is a gasket, and the thread only serves to provide a pressing force.
The maze sealing effect is very good when the design is reasonable, the processing is excellent, the assembly is good, and the rotation speed is high. However, in practical applications, the resulting chemical pump leaks are numerous, so it is not commonly used in chemical pump seals.
The filler with compressibility and resilience is placed in the stuffing box, and the axial pressing force of the gland is converted into a radial sealing force, thereby sealing.
This method of sealing is called a packing seal and this packing is called a packing. Because the packing sealing structure is simple in form, convenient to replace, low in price, suitable for speed, pressure and wide medium, it is widely used in the design of chemical pumps.
When the chemical pump is in operation, the indenter generated by the auxiliary impeller balances the high pressure liquid at the outlet of the main impeller to achieve sealing. When parking, the auxiliary impeller does not work, so it must be equipped with a parking seal to solve the chemical pump leakage that may occur when parking.
The auxiliary impeller has a simple sealing structure, reliable sealing and long service life. The drip water can be prevented from leaking during the operation of the chemical pump, so it is often used in the pump of the chemical pump to transport the impurity-containing medium.
Nowadays, the chemical pump industry is the most widely used sealing form. Because mechanical seals have the advantages of less leakage and long life, mechanical seals in the world are the most important shaft sealing methods in these devices. Mechanical seals, also known as end seals, are defined in the relevant national standards: "The at least one pair of end faces perpendicular to the axis of rotation are held together by the action of the fluid pressure and the compensating mechanism's spring force (or magnetic force) and the auxiliary seal. a device that prevents fluid leakage by sliding relative to each other."
The main advantage:
● easy to repair
●The whole series of water conservancy performance layout is reasonable
●User selection range is wide
● "Back open" structure
● Efficiency and suction reach international advanced level
