Q:How much water does the water ring vacuum pump run for an hour? If there is no steam separator, does the water vaporize?
Water ring vacuum pump is divided into many types, different sizes, different types, so water is different. As for how much water the no fixed amount, but to ensure that the water temperature is in 25 degrees, not more than 35 degrees can be.
Q:60 type concrete pump performance?
Specification for concrete cylinders:Bore * stroke mm 200 * 1650Hopper capacity L 800Feeding height mm 1400Motor model Y2-280M-4Power kw 90Rated voltage V 380Rated speed r/min 1480Soft starter withoutHydraulic system open-loop
Q:Double floor sewage pump circuit diagram of a small problem
Question 3 when the water level is low, when the 1KA is connected, the pump will run depending on where your SS selector switch is located. Its left and right position, running pump and standby pump definition is different, left position is 1#, running 2# standby, right position is 2# running, 1# standby. Only inIn case the high level switch 2KA is connected, the standby pump may work at the same time.
Q:What's the difference between non negative pressure and variable frequency water pump?
When peak water is used, the fluctuation of water pressure will be the same for customers! Because the key to the fluctuation of hydraulic pressure is the flow rate of the pump and the lift of the pump. As long as the flow of the selected pump is large enough, the tank is large enough, the lift head is suitable, and the pressure fluctuation is relatively small. And the selection of non negative pressure and frequency conversion pump group is not directly related. If the municipal tap water pressure and water sufficient (large enough diameter), the use of non negative pressure is better. If the municipal tap water pressure and water shortage, you can only use the frequency converter pump + water tank, no negative pressure can not be used.
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:Why is the submersible pump tripped on an electrical switch?
Submersible pump cable or motor insulation is damaged.3) motor water solution
Q:Advantages and disadvantages of centrifugal pumps?
The centrifugal pump has no valve, so it is suitable for conveying suspended liquid, and the special design can also transport large solid suspensionThe pump can be made of chemical resistant material, which is suitable for conveying corrosive solution.The utility model has the advantages of simple structure, few parts, little failures, durability, low maintenance cost, convenient management and reliable work.The output can be adjusted even by the discharge valve fully closed, there is no danger of infinite rising pressure head.The liquid is transferred to a large quantity. And the pressure head does not require large, most suitable for centrifugal pump.
Q:What is a water pump coupling device?
The water pump coupling device comprises a coupler, a coupling flange, a guide rod and an upper fixing plate, wherein the contact surface of the coupling base and the coupling slide plate is provided with an annular groove, and a soft sealing gasket is tightly fixed on the groove. By adopting the structure, the coupling contact surface of the coupling slide plate and the coupling base is sealed firmly by an annular sealing groove
Q:Is the centrifugal pump large or small?
Centrifugal pump, the smaller the better the cavitation.1, centrifugal pump cavitation less, anti cavitation performance is better, the pump cavitation is called the necessary cavitation margin or pump inlet dynamic pressure drop, the smaller the better. Generally speaking, the pump cavitation is the need for cavitation, the pump inlet pipe said effective cavitation margin, that is, the device cavitation margin. For a given pump, at a given speed and flow rate required NPSH is called pump necessary NPSH, also called NPSH, is required to achieve the performance parameters of the pump cavitation, the internal flow and the centrifugal pump is composed of pump head itself, its physical meaning is that liquid drop in pump inlet pressure part degree, is to guarantee the pump cavitation does not occur, with surplus energy exceeds the vaporization pressure head at the inlet of the pump unit weight of liquid. The cavitation must be independent of the device parameters. It is only related to the parameters of the inlet of the pump. These parameters are determined by the geometric parameters at a given speed and flow.
Q:What's the pump? Where can I use it?
A pump is a machine that transports liquids or pumps liquids. Pumps are ubiquitous in life. They can be used to transport liquids such as water, oil, acid and alkali, emulsions, suspensions and liquid metals, as well as liquids, gas mixtures, and liquids containing suspended solids.
