- Q: What is the relationship between the minimum suction vacuum of a pump and the required cavitation?
- When the pump is working, the liquid at the inlet of the impeller, due to a certain vacuum pressure will produce steam, the vaporization of the bubble in liquid particles under the impact of movement, the impeller and other metal surface erosion, thereby damaging the impeller and other metal
- Q: Is the vacuum pump air compressor?
- A vacuum pump is a device or device that uses a mechanical, physical, chemical, or physical chemical method to pump a vacuum from a container to be evacuated. Generally speaking, a vacuum pump is a device that uses various methods to improve, produce, and maintain a vacuum in a confined space.
- 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 the lift off the dead center point? This is a straight mark about the water pump. What is the function and the relationship between the design head and the pump head? ThanksWhat exactly is the dead point lift? What's the function of this indicator?
- Pump downstream equipment design pressure is greater than 3MPa, if it is 400 meters, the downstream equipment design pressure is greater than 4MPa
- Q: What are the application areas of pumps?
- Performance range from the pump to see giant pump flow up to hundreds of thousands of cubic meters per hour, while the micro pump flow per hour in a few milliliters; pump from atmospheric pressure up to 19.61Mpa (200kgf/cm2); the lowest temperature of the liquid is transported up to -200 DEG C, up to 800 DEG C. Pumps carry a wide variety of fluids, such as water (clean water, sewage, etc.), oils, acid and alkaline solutions, suspensions, and liquid metals.In the chemical and oil sector production, raw materials, semi-finished products and finished products are mostly liquid, and semi-finished and finished products to raw materials, need to go through a complex process, to pump and provide transportation of liquid chemical reaction of the pressure and flow in the process, in addition, the device also used in many pumps to adjust the temperature.In agricultural production, the pump is the main irrigation and drainage machinery. Rural areas in our country are vast and vast, and a large number of pumps are needed every year in rural areas. Generally speaking, agricultural pumps account for more than half of the total output of pumps.Pumps are also the most widely used equipment in the mining and metallurgical industries. The mine needs pumping and drainage. In the process of ore dressing, smelting and rolling, the pump needs water to supply water first.
- Q: What are the basic technical parameters of the pump?
- The basic parameters of the pump, the basic parameters of the main performance parameters of pump are the following: first, water pump flow Q flow is the amount of liquid in the pump unit time delivery out (volume or quality). The volume of flow with Q that the unit is: m3/s, m3/h, l/s and so on. The quality of flow unit is expressed in Qm. T/h, kg/s and so on. The relationship between mass flow and volume flow is Qm= P Q density in P - liquid (kg/m3, t/m3), room temperature water P =1000kg/m3.
- Q: Brief description of centrifugal pump on / off operation
- Two, centrifugal pump start(1) the pump entrance valve fully open, start motor, outlet valve fully closed, fully check operation of pump.(2) when the pump outlet pressure is higher than the operation pressure, the outlet valve is gradually opened to control the flow and pressure of the pump.(3) check whether the motor current is within the rated value, such as the pump in the rated flow operation, and the motor overload should stop the pump inspection.
- Q: Does the reservoir water heater press the booster pump (high marks)?
- The outlet water pressure of hot water is the same as that of cold water. The water heater is pushed by cold water to push out the hot water. (of heating). Installation location about 2 meters away from the ground, the impact of water pressure is not large, in rural areas, the installation position in more than two buildings will have an impact. In the city, the installation position is above four floor to affect the water pressure.
- Q: What's the meaning of the pump head in the water pump, please advise, thank you
- According to China Wikipedia network, the basic components of the water pump: motor, coupling, pump head (body) and chassis (horizontal).Pump is generally composed of pump body and pump head, in which the pump body refers to the spiral case, impeller, bearing, oil shell and sealing assembly, etc., the pump head refers to the impeller, bearings, oil ring and sealing rotating parts (including shaft), etc..
- Q: Is the sewage pump the same as the mud pump?
- No. the main functions are different:1, pump two main performance parameters is the 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
