Q:What are the ways of hydraulic pumps?
Check valves, such as single piston pumps, three piston pumps, etc.;The port of the valve arrangement, such as the radial piston pump.
Q:How to maintain and repair the booster pump of pipeline pump?
I. installationAssembly and disassembly1. scrub all the spare parts to be cleaned.2. mechanical seals are installed on the main shaft of the motor, and a small amount of clean turbine oil or 20 oil is added to the surface of the mechanical seal.
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 do we need to stop the pump?
The valve opening pump is aimed at the centrifugal pump.From the power curve of the centrifugal pump, the power of the centrifugal pump increases with the increase of the flow rate; the flow curve of the centrifugal pump shows that the flow rate of the centrifugal pump decreases with the increase of the head.
Q:Attention should be paid to the use of pumps?
7 water pump and pipe interface must be sealed, because if there is debris access, then the pump will cause damage to the interior. 8 for the water pump bearing is also the focus of inspection, use up to check whether the bearings wear,
Q:Direct connection pump What is straight pump and non direct pump? What's the difference in structure?
What is straight pump and non direct pump? Direct coupled pump shaft and the motor shaft is directly coupled with the coupling and non direct coupled pump: pump shaft and motor shaft through the belt pulley, V-belt connection or other forms of transmission. What is the difference in the structure: the direct coupled pump has the advantages of compact structure, simple installation, but the relatively small power; non direct coupled pump: pump and motor is independent, the two transfer torque through the belt, the structure is relatively large, complex installation, general power is relatively large.
Q:The difference between diaphragm pumps, vacuum pumps and centrifugal pumps
The diaphragm works by changing the size of the diaphragm. When the cup is covered with an eraser and the edge is airtight, then pressing the rubber or pulling the rubber outward will make the pressure in the cup increase or decrease. Use this principle, in the pressure of an hour from a hole suction medium, when the pressure is large, from another hole extrusion medium, so as to achieve the purpose of conveying.
Q:Fire hydrant pump button, under what circumstances do not need to install?
General high voltage system, when normal, use small pump steady pressure.Fire hydrant button lifting pump is one of the multiple pumping methods, and it is an important link of reliable operation of the system.
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:What is a solution pump?
2.1 advantages of canned pumps(1) fully enclosed. There is no dynamic seal in the structure. Only the static seal in the outer shell of the pump can be made without leakage. It is especially suitable for transporting flammable, explosive, precious liquids and toxic, corrosive and radioactive liquids(2) high safety. The rotor and stator each have a shielding sleeve, so that the rotor and stator of the motor are not in contact with the material, even if the shield is broken, it will not produce the risk of leakage and leakage(3) compact structure and small footprint, the pump and motor is a whole, disassembly and assembly do not need to find the center. The base and foundation requirements are low, and the daily maintenance workload is low, and the maintenance cost is low
