Q:Types and differences of pumps
(I) volumetric typeClassification reciprocating rotary typeThe basic principle of reciprocating action by the piston in the cylinder in the cylinder volume changes again, with the suction and discharge of fluid in the shell or the rotor rotating member rotates, the volume of work between rotor and casing changes to the suction and discharge fluid, such as piston pump gear pump, screw pump(two) blade type;The main structure of vane pumps and fans is rotary, bladed impellers and stationary housings that rotate fluid through the impeller to do work, thereby enabling fluids to obtain energy
Q:Piston filling and peristaltic pump filling which precision is high?
First of all, we should know the working principle of each, and analyze the accuracy from the principle, this problem is very important. Piston filling, such as the injection of drugs that we have been ill, the accuracy of the piston pump depends on the accuracy of the motor and the area of the unit cross section
Q:Is the flow meter in front of the pump or after the pump?
After the flowmeter is placed in the pump, it is better to add a pressure tank or a buffer tank, so that the flow meter will work better
Q:Why is the flow of the pump too small will occur cavitation phenomenon?
This is because the impeller of the centrifugal pump rotating speed under the drive of the prime mover, when the valve opening decreases, flow rate is too low, can not be taken away by the friction heat generated by the impeller and the liquid completely, make the temperature of the liquid inside the pump. Thus causing liquid vaporization, forming cavitation. Especially in the power plant, the boiler feed pump is more remarkable. Therefore, when throttling regulation, we should set up recirculation system, increase the output flow of the pump to prevent cavitation. When the feed water rate is reduced to 1/3 of the maximum flow rate, the recirculating gate shall be opened so that the flow of the feed pump will be increased properly to ensure that the liquid temperature in the feed pump does not rise.
Q:Why do we need to stop the pump?
And the pump at the start, if the valve opening pump, then the pump outlet pressure (head) is very small, so the pump flow will be great, the pump power is very large, causing the start-up current is very large. In addition, the starting current of the motor itself is also very large. These two factors add up to the possibility of overloading the motor, resulting in failure to start or even burn the motor.
Q:Concrete pump 125 pipe wall thickness
Concrete pump diameter 125mm, pipe wall thickness is generally 4mm, also have 4.25mm, 4.5mm, 4.75mm, need to be in accordance with the rules of transport.
Q:What is the nominal pressure of the hydraulic pump and hydraulic motor?
Working pressure - the actual working pressure of the motor, that is, the pressure of the input oil. The difference between the motor inlet pressure and the outlet pressure should be calculated.Rated (nominal) pressure under normal working conditions, according to the test standards for continuous operation of the maximum pressure, that is, the rated pressure, more than the maximum pressure is called overloading.
Q:Excuse me, what is the water pump from the lotus root?
The utility model relates to a self coupling sewage pump, which is composed of a base, a self coupling frame, a guide rod, a guide rod, a support seat, etc., and the utility model does not need bolt connection
Q:Centrifugal pump flow, why can be adjusted through the outlet valve?
Centrifugal pump, and is a very common method of centrifugal pump, flow with the head (or pressure) increases, off a small valve resistance increases, the pump head should be increased, then the flow decreased, whereas open valve flow increase
Q:What is the Rhodes pump?
Work principle editorRoots-type pump is a vacuum pump without internal compression, usually compression ratio is very low, so high and medium vacuum pumps need pre pump.A vacuum pump for pumping air by pumping a gas by the simultaneous rotation of a pair of lobed rotors in a pump cavity and a reverse rotation.Roots vacuum pump is a mechanical vacuum pump with a pair of synchronous and high-speed rotating sole shaped rotors. The pump can not be drawn out separately. The front stage needs to be equipped with an oil seal and a water ring, etc. it can be discharged directly into the atmosphere.
