Q:Water pump belongs to power equipment or mechanical equipment?
Ownership of mechanical power equipment in assets
Q:Is the motor with a pump a squirrel cage induction motor?
Should be a squirrel cage motor for winding asynchronous motor for high torque applications. For example, its structure and the hoist crane cage motor with different rotor loop it can slip ring external resistor. The motor rotor circuit principle know that certain external resistance can reduce the starting current, but also can improve the rotor circuit power factor and torque. The pump load does not need large torque. So it should be the squirrel cage induction motor.
Q:Should the no-load power of the pump be equal to the rated power?
We must first clear the meaning of rated power; rated power is called the reference numerical electrical power consumption in the voltage conditions specified, and the actual power consumption of electrical appliances is different in different situations, the pure resistance (such as lighting, electric) as long as the voltage conditions, the actual consumption of electric power close to or equal to the rated power, and for appliances like motor, electric power consumption, not only related with the voltage, but also with the relevant load. For example, someone with 200 pounds of energy, then the person in the condition of small meal, maximum load of 200 pounds, but if you take as long as he is 100 pounds, of course he relaxed, he would not say must bear 200 pounds!You measure the pump power is less than 1200W, first you did not mention your use of voltage is not rated voltage, then you don't want him full load, the suction is far less than 8 meters, there is no mention of whether you send water to 50 meters (Yang Cheng), there may be insufficient voltage, and you have don't need it so much power consumption. Of course, one advantage is that it doesn't burn easily. It is easy to burn if it is used at full load.
Q:Can the water from the fire pump enter the roof fire tank? Why?
Fire water pump water can not enter the roof, fire water tanks, "construction regulations" and "high regulations" clearly defined. The roof fire water tank acts as a temporary fire fighting water for 10 minutes, and the water in the fire pump is supplied directly to the indoor hydrant or sprinkler system. Roof water tank fire water can only be provided by the living pump.
Q:When did the pump start?
The promotion of water is very important to human life and production. There are various ancient water appliances, such as Egypt's chain pump (seventeenth Century BC), China shadoof (seventeenth Century BC), Burton (Eleventh Century BC) and water (first Century ad). The famous spiral rods invented by Archimedes in the third Century BC can lift water to a few meters in a steady and continuous way, and the principle is still used by modern screw pumps.In 200 BC, the ancient Greek fire pump craftsmen invented by Kurt Siby Lucius is a kind of piston pump has the most original, the main components of a typical piston pump piston pump, but only after the steam engine was developed rapidly.1840~1850 years, the United States invented Worthington pump cylinder and steam cylinder opposite, the direct impact of the piston pump, marking the formation of modern piston pumps. Nineteenth Century was the climax of the development of piston pumps, which were already used in a variety of machines, such as water presses. However, with the rapid increase in water demand, from 1920s, the piston pumps with low speed and large flow were gradually replaced by high-speed centrifugal pumps and rotary pumps. But in the field of high pressure and small flow, reciprocating pump still occupies the main position, especially diaphragm pump and plunger pump have their own advantages and are used more and more.
Q:What are the commonly used tools for repairing water pumps?
Because had done a mechanic, and relates to a pump, not including motor repair, commonly used tools: pliers, pliers, adjustable wrench, wrench, screwdriver, bench drill, multimeter, electric iron, Lamar, hammer, ruler, chisel. Commonly used parts: bearings, impellers, screws, terminals, lubricants and so on.
Q:Pump pumping small is what happened?
Water pump pumping is small because of insufficient water source or pump head is not enough. At the outlet stop to measure the pressure, if there is a certain pressure, that is, the flow is too small, if there is no pressure, that is not enough head, or both small.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:Explore the flow of water pump production process is like?
The main flow of water pump (take centrifugal pump as an example):Technical determination of Drawing > raw material storage > mold preparation > casting moulding > machining > parts experiment > Assembly > performance experiment > painting packing > storage.Here are a few key steps:1) the technique determines the graphMainly the work of designers. Generally according to the parameters of the pump (flow, lift, cavitation, efficiency, etc.) to determine the specific speed of pumps, impeller form, impeller size, impeller material, pump body, pump shaft and so on. One of the most important thing is to draw the impeller woodenpatterns.2) die preparationThe mold is mainly composed of workers according to the water pump impeller woodenpatterns production model.3) casting moldingThe casting molding sand is made on the base of the mould.4) machiningWater pump parts processing, because it has hydraulic flow channel, in considering the positioning clamping standard, must find the correct flow channel of the correct position. Avoid assembly, resulting in water pressure chamber and impeller flow channel skew, dislocation, uneven gap, or even rub, affecting product quality. In order to ensure the accuracy of parts manufacturing, it is necessary to design the appropriate tooling, and reasonable arrangements for technological processes, control process factors.
Q:Fire pump room is required to set up water pump control room?
What is the concept of fire pump control room? If there is a control room host automatic alarm automatic fire alarm system of words (through the pump distribution box can also control) can control the fire pump, if there is no distribution box automatic alarm system you can through the pump room control
Q:Water pump maintenance what should be maintained?
1 by sound to determine whether the bearing is good. If the sound is abnormal, replace the bearing.2, check whether the impeller is worn, if worn, will affect the flow, lift, efficiency, need to be replaced.3, check whether the mechanical seal can continue to use, can not be used, need to be replaced4, check the oil tank is missing oil, such as lack of oil to the appropriate location.
