Q:What is the pumping property of concrete?
Under a certain pump pressure, the farther or higher the concrete can deliver, the lower the probability of clogging, the better the concrete pumping performance.
Q:Bolus dosage of infusion pumpWhat is the purpose of the pill dose control in the special safety standard for infusion pumps? If the risk is not properly controlled, what is the degree of risk? And how can the open infusion pump be used in this regard?
(1) the pellet dose in the safety standard of the infusion pump refers to the amount of liquid that is transported to the patient in a short period of time(two) pill dose limit is mainly to control the risk of accidental pill dosage. Especially after the mandatory requirements of pipe blockage in the elastic pipe storage liquid limit amount of agglomeration and the limitation of these methods to release pill dose.
Q:What is the name of the day pump and ground pump? Specific introduction
Day pumpDay pump is called "day pump", the main reason is that it can deliver concrete to a certain height, make up for other concrete pump transportation shortage. Compared with other concrete pumps, the pump has its own boom, and the concrete can be transported without the use of artificial cloth. It is very convenient for use. At present, China's longest boom pump is 101 meters, which means that 101 meters under the floor can be completed with the help of day pump concrete delivery. In addition, the pump is equipped with a chassis, so compared with the ground pump, it can walk independently, moving very convenient, you can quickly move from one site to another location.
Q:How to distinguish the flow and displacement in the hydraulic pump? What's the difference between the two?
For example, once you sprinkle water from the tank to the ground, one shot of water is 1000 milliliters, which is equivalent to displacement, once (pump turn) 1000 ml.,
Q:What's the meaning of the pump head in the water pump, please advise, thank you
In general, the pump removes the motor, and all the fittings are part of the pump head.A pump is a machine that transports liquids or pumps liquids.
Q:Piston filling and peristaltic pump filling which precision is high?
If the unit area is large, the accuracy of the plunger is certainly not high. The peristaltic pump is used by means of extrusion roller extrusion pump to promote the solution, this also depends on the unit cross section size, the same motor accuracy is very important.
Q:How to select hydraulic pump?
1. rpmOperating speed is the actual rotation speed of a pump (or motor) at work.Rated speed is the maximum speed that can operate normally for a long time under rated pressure. If the pump exceeds the rated speed, the work will cause insufficient oil absorption, vibration and noise, the parts will suffer cavitation damage, life expectancy.Minimum steady speed is the minimum speed allowed for normal motor operation. At this speed, the motor does not appear crawling phenomenon.
Q:What is the principle of a turbopump?
A machine that converts the energy contained in a fluid medium into mechanical work [turbine]. Also known as turbines, turbines. Turbine is the transliteration of English turbine, derived from the Latin word "turbo", meaning "rotating object". The working conditions of turbines are different from those of the employed ones, so their structure types are various, but the basic working principle is similar. The most important component of a turbine is a rotating element (rotor or impeller) that is mounted on a turbine shaft and has blades uniformly arranged along the circumference. The energy of the fluid is converted into kinetic energy in the flow through the nozzle, and when the fluid passes through the rotor, the fluid impacts the blade and drives the rotor to rotate, thus driving the turbine shaft to rotate. The turbine shaft drives the other machinery directly or through the transmission mechanism, and outputs mechanical work. According to the turbine working fluid used can be divided into different turbine (used as a power source of Hydropower Station) and steam turbine (used in thermal power plant, ship propulsion), gas turbine (used as jet propulsion, ship power, and power plants, with a small peak load power station and air turbine (only) as a small power).
Q:Know flow and lift how to calculate the pump power?
The pump power (kw) ={9.61* flow (cubic meters per second) * head (m)}/.Where ETA is device efficiency, including mechanical, electrical loss and other factors, generally between 55%~80%. The smaller the pump, the lower the efficiency.
Q:Direct connection pump What is straight pump and non direct pump? What's the difference in structure?
Direct connected pump: pump impeller installed directly on the motor shaft, it looks like a whole, relatively compact, simple installation, but the general power is relatively small (big bad processing connection, but not absolute);Non direct pump: pumps and motors are independent of each other, through the coupling torque transmission, the structure is relatively large, complex installation, to adjust the level / concentricity and so on, the general power is relatively large
