Q:Piston filling and peristaltic pump filling which precision is high?
These two pumps are used as a metering pump to use, so the accuracy is to be on a par with the peristaltic pump has more advantages than the piston pump is the largest energy fluid conveying there are particles, and the piston pump is smaller than the peristaltic pump pulse, so we need to choose according to the material characteristics you need to transport.
Q:What does "efficiency" mean in a water pump catalog?
Pump efficiency: the ratio of the effective power and the pump shaft power
Q:Must the water pump in the tank be all soaked in water?
Of course, if the motor is overheated, it will burn, and the temperature of the water will drop down.
Q:Significance of water pump model ISO50-160
A pump is a machine that transports liquids or pumps liquids. It will be the prime mover of the mechanical energy or other external energy transfer to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids. Pump performance parameters include flow, suction, lift, shaft power, water power, efficiency and so on;
Q:How is the pump level of submersible sewage pump determined?
Generally as:The bottom elevation of sump sump plus 300 is the water level of pump stopThe top 300 of the sump top elevation is the pump water level
Q:What is the dry running protector of screw pump? What's the principle and function? Thank you
When the temperature reaches a certain value, the signal is transmitted to the electric control box through a dry running protector, and the electric control box is used to stop the screw pump so as to protect the screw pump.
Q:What are the conditions required for hydraulic pumps to complete oil absorption and compression?
2, the change of working volume is periodic, and in each cycle, the oil absorption process is changed from small to big, and the process of oil pressure is changed from large to small;3, suction oil cavity must be separated from each other without interference.
Q:Is vane pump good or gear pump good?
The main parts of a gear pump are gears that mesh with each other. The meshing driving gear and the driven gear are respectively arranged on two parallel rotating shafts. Because the gear teeth enter and exit the meshes, the volume of the teeth is changed, and the suction and discharge effect is formed.
Q:Pump unloading in hydraulic transmission,
Unloading water, from the literal interpretation is along the pump, leakage of water seal through the head, the water with certain pressure (even with relief effect seal). The water as the working quality is asked to be recycled, now the design of some use it as a water seal, and others by direct recovery, but eventually recovered.
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
