Q:What's the difference between a concrete pump and a concrete pump truck?
Concrete conveyor pump height and distance can reach hundreds of meters, which is far more than pumping vehicles, but it needs cloth tube, not flexible enough. Less investment.Pump car use more flexible, higher investment.
Q:Attention should be paid to the use of pumps?
1, pump shaft packing completely worn, it is necessary to add in time, if you continue to use the water pump will leak. The direct effect of this is the increased energy consumption of the motor, which will damage the impeller. 2, the use of pumps in the course of a strong vibration, then must stop to check the reasons, or the same will cause damage to the water pump. 3 gear pump valve Water Leakage, some will use the soil into the water pump inlet tube, the water washed in the end valve, this is indeed undesirable. Because when the dry soil into the inlet pipe, when the pump started working, these dry soil will enter the pump, which will damage the pump impeller and bearings, which shorten the service life of the pump. When the valve Water Leakage must take to repair, if it is serious that it is necessary to replace the new. 4 after the use of pumps must pay attention to maintenance, for example, when the pump is exhausted, we should put the water pump who put clean, it is best to remove the water pipe, and then rinse with water. 5 water pump on the tape should also be written down, and then always flush, and then light out to dry, do not put the tape in the dark damp place. Water pump tape must not be stained with oil, not to tape coated with some sticky things.
Q:Significance of water pump model ISO50-160
According to different working principles can be divided into volumetric pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.
Q:What are the causes of pump shock?
3. the water pump set screws loose, adjust the concentric, fastening the foot4. pump into foreign body, open cover overhaul5. the flow is too large or too small, adjust the equipment to control the water output
Q:What are the internal losses in centrifugal pumps? How did they come about?
Hydraulic loss: the loss of water by friction, eddy, impact, etc in a flow;
Q:Suction stroke and lift of water pump
The absorption process is also called the "largest self-priming height" (also can be understood as "the degree of self suction). Micro pumps do not add water at the circumstances, can automatically water suction pump up the maximum height (the vertical distance from the pump to be pumped from the mouth of pumping liquid).Generally lower than the water pump positioned equal when there is self-priming pump required capacity. For example, outdoor tourism, need to extract the water in the river, with the best micro pump self-priming ability (impossible to people ran to the river water inlet pipe with water. It) or pumping the liquid corrosion, easy to add water and so on occasions.
Q:What is the relationship between the minimum suction vacuum of a pump and the required cavitation?
When the vacuum pressure is called vaporization pressure, cavitation is more than the surplus energy of vaporization pressure at the unit weight of the liquid in the pump suction port of the unit, with mark. The absorption process is to NPSH delta H: pump suction fluid allows the vacuum pump installation height is the unit of rice.
Q:What is a feed pump?
In general, high lift pumps are required with a front pump (which is similar to the feed pump of the landlord) or a low position;
Q:Operating procedures for measuring pumps
3, discharge pipeline unimpeded.4, the pipeline should meet the positive pressure head, that is, in high flow suction conditions work.5, check the direction of the pump, strictly prohibited reverse.6. Check the oil level in the crankcase compartment. For multi cylinder pumps, check that the oil level has reached the required level.7 、 pump motor static grounding is good, meet the requirements.
Q:What is the displacement of the pump? Flow? What is the volume efficiency and mechanical efficiency of the pump?
Mechanical efficiency: the ratio of theoretical torque to actual torque of the pump.
