- Q: Why should the pump be closed when the centrifugal pump is started?
- Therefore to close the outlet valve, the pump during starting output water, the minimum pump power, when the pump reaches the rated speed, slowly open the outlet valve, gradually increase the flow of water, the motor current is gradually increased to the rated current.
- Q: 5 floor water pressure is too low, what kind of water pump is better?
- Pipe blockage, leaks, or throttling devices are not opened. This can be tested on a pipe with a pressure gauge;Water pump is equipped with power source, power or speed does not match, check the pump and power end nameplate, power end of the pump power is generally 1.1.5 times;
- Q: How does the centrifugal pump pump and cut the pump?
- Turn on the motor, observe the motor current, turn from high to low, observe the pump outlet pressure, and the pressure rise;Slowly open the outlet valve, so that the pressure drop slowly, the current slowly rising to the stable, the outlet valve to the maximum;Check the pump operation, stuffing box leakage, current, whether or not the rated current, motor, bearing temperature is normal, whether or not abnormal sound.
- Q: What is the pump, how to classify, mainly used in where?
- 1. vane pumpThe impeller pump is driven by the impeller to rotate the liquid at high speed and transfer mechanical energy to the transported liquidAccording to the pump impeller and runner structure characteristics can be divided into different:1) centrifugal pump2) axial flow pump3) mixed flow pump4) vortex pumps3. jet pumpA high velocity jet produced by a working fluid is used to eject the fluid, and then the energy of the ejected fluid is increased by momentum exchange
- Q: The difference between submersible pumps and centrifugal pumpsWhat's the difference between the two? What is applicable and what?
- 1. submersible pumpsA very wide range of water treatment tools. Unlike ordinary water pumps, it works underwater, while the pump works mostly on the ground.The working principle of submersible pumpBefore the pump is opened, the suction pipe and pump must be filled with liquid. Open the pump, the impeller rotating speed, which leaves the liquid together with the rotation under the action of centrifugal force, the left outside impeller injection, injection of the liquid in the pump shell gradually slow the spread of indoor speed, the pressure gradually increased, and then from the pump outlet, the outflow discharge tube. At this time, in the leaves at the center of the vacuum area of low pressure liquid was thrown to the surrounding formation there is no air and no liquid, liquid pool at the surface of the liquid under the action of atmospheric pressure, through the suction pipe into the pump, the liquid is continuously pumped up from the liquid pool is also continuously from the outflow discharge tube.Basic parameters of submersible pumpIncluding flow, lift, pump speed, matching power, rated current, efficiency, diameter and so onSubmersible pump main application and scope of applicationIncluding construction, construction, drainage, agricultural irrigation and drainage, industrial water recycling, urban and rural residents cited water supply, and even rescue, disaster relief and so on
- Q: There are second cutting, third cutting, why three times?
- I used to do this job before. After the impeller is cut, the flow and lift will decrease. Sometimes, the same pump will be cut according to the needs of the impeller, so as to meet the actual needs, at this time, with the power of the motor will also be reduced
- Q: Household automatic booster pump, how much pressure to work automatically, the water pressure and how many kilograms?
- Start the pump. Water pressure depends on how large you buy the pump, generally small, mostly 10-15 meters hydraulic pressure, about 200 of the price.
- Q: What do you mean by the self coupling device on the pump?
- Installation of GAK self coupling device:The installation of automatic coupling submersible sewage pump is mainly the installation of coupling device and the lifting of pump. In the pump before the installation of the rings on the chain, and the pump used for lifting.Installation procedure of coupling device:The coupling frame with four bolts fixed on the pump body; the water outlet pipe is fixed on the substrate; positioning cone mounted on the pipe seat; the lower end of the guide pipe is sleeved in the positioning cone, the upper end is sheathed on the guide rod of the rubber block; the guide rod frame is fixed on the pool wall. The function of the rubber block: the axial compression degree of the rubber block is adjusted by the screw on the guide rod frame, so that the diameter of the rubber block is consistent with the inner diameter of the guide rod, and the guide rod is stable.
- 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: What's the submersible pump?What is a submersible pump, and what about it?
- Not afraid of water, because it is placed in the water itself to cool themselves, you can use for a long time. The amount of water pumped and the height of the water now basically meets the needs of a small amount of individual and a large number of factories. This is the submersible pump, the water pump in the water. You can see.
