Q:How many kinds of pumps are available and the operating principles of various pumps?
The volume type pump, depending on the periodic change of sealing liquid containing space volume, the energy is periodically transmitted to the liquid, the liquid pressure increased to force the liquid discharge, according to the motion form of work elements can be divided into reciprocating pump and rotary pump. Other types of pumps transmit energy in other forms. As the jet pump work on high-speed jet of fluid will be required to transport fluid suction pump after mixing for momentum exchange in order to transfer energy; water hammer pump by water when braking in the flow of energy transfer is to rise to a certain height; the electromagnetic pump is energized to make the liquid metal in the electromagnetic forces generated in the flow and transport. In addition, the pump can also be classified according to the nature of the transmission fluid, driving methods, structure, use and so on.
Q:What are the characteristics of a pipe shield pump?
According to the transmission of liquid temperature, pressure, viscosity and particle level have different requirements, the pump can be divided into the following types: first, the basic type (standard type) transport medium temperature does not exceed 120 degrees, the head of not more than 100m, the pump other types are variations on the basic type and improved.
Q:Fire pump control cabinet There are 6 pumps, two indoor fire hydrant pumps, two spray pumps, and two outdoor pumps
Spray pump in addition to remote direct Kai, there are modules to start function, that is, on the cabinet to add control module, bus linkage pump, in addition to the pressure switch, directly pumping function, a total of three functions.
Q:What are the functions of a disposable infusion pump?
With the development of science and technology, more and more fields need to control the flow or velocity of fluid accurately. For example, the detection and analysis of micro chemical elements in chemical industry always need to control the flow accurately. In the field of health care, the flow and velocity of traditional Chinese medicine liquid must be controlled accurately.Venous transfusion is one of the most commonly used methods of clinical treatment. It is a common medication and treatment technique for nursing specialty. Clinically, appropriate infusion rate should be applied according to the drug and patient's condition. Transfusion too fast may cause poisoning, more serious can lead to edema and heart failure;
Q:What is the distance between the pump and the wall?
Mainly depends on the maintenance, installation is convenient, but there is no other requirements.
Q:What is the minimum continuous flow of a pump?
At'-- the allowable temperature rise of pumping medium,C- pumping medium specific heat, kj/ (kg DEG C);Ho- off dead center lift, M.Minimum continuous flow minimum continuous stable flow and minimum continuous thermal flow and the maximum value in the selection, or use the pump process, the minimum continuous flow process requirements must be greater than the minimum flow rate of the pump, otherwise it will cause the pump cavitation, vibration and noise, so that the pump parts damaged. If the minimum continuous flow the pump can not meet the minimum requirement's process, can install the bypass reflux device or reflux system in the pump pipeline, to ensure that the minimum continuous flow pump.
Q:How is the pump level of submersible sewage pump determined?
Below the top elevation of the sump, 200 is the warning water levelBut note: 1, the effective volume of the sump meets the requirements. 2, the pump should have enough submerged water level
Q:What is the difference between swashplate pump and crankshaft pump?
Swash plate pump motor is driven as a coaxial swash plate drive plunger pump crankshaft work produces high pressure water in general simply and motor rotor to form a 90 degree angle of the motor through the crankcase to drive the piston to work in general the crankshaft speed is relatively high in the 2800 turn left and right to use the cost of the swash plate speed the use of less than 300 kg pressure in about 1400 when the crankshaft is relatively high but in more than more than 300 kilograms of crankshaft pump highlights his advantage.
Q:What should I pay attention to when buying a pump?
Four, packing inspection1. with the pump supply documents shall include: product certification, specification, packing list, agricultural pumps (such as submersible pumps, centrifugal pumps, mixed flow pumps, self-priming pump etc.) should be "Three Guarantees certificate", the implementation of the production permit (such as pump submersible pump, high pressure pump, high temperature pump 5 pump) we should have a production license.2. plugging of the orifice, to withstand wind and rain invasion, and should be strong, can withstand accidental damage.3. pumps and all supplied bulk parts supplied with the pump shall have the required identification number and shall be clear.4. pairs of oil lubricated bearings, bearings tank oil should be discharged, and fixed with "need oil filling" warning signs.
Q:How to distinguish the flow and displacement in the hydraulic pump? What's the difference between the two?
If you're allowed to spend a minute, you can do it 20 times a minute, and that is, the amount of water you sprinkle at a time (1000) is *20.1000 (ML) *20=20000 ml =20 liters, this is the flow,Here is a formula for you to see,Pump displacement * pump speed = flow,
