Q:What is a positive displacement pump? He Weizheng displacement?
The principle and structure of positive displacement pumps are similar to those of hydraulic motors. Positive displacement is the pump outward to provide flow and pressure, that is, conventional pumps. A negative displacement pump is a hydraulic motor that rotates by external pressure and flow.
Q:Why should the pump be closed when the centrifugal pump is started?
On the other hand, the water on the pipe of the inlet pipe of the pump is stationary before the pump is opened, such as the sudden acceleration, and the water behind it can not keep up, which will cause the pressure of the inlet to drop suddenly and vaporize the water, and the centrifugal pump will be evacuated. (because of the centrifugal pump is rotating centrifugal force generated by the pump, leaf water and steam driven (gas) quality is very light, according to F= Ma, the centrifugal force is small, the pump can not be water sent).
Q:How to adjust the flow of piston pump?
The oil pan with oil liquid through the suction port and the piston cylinder; from 180 degrees to 360 degrees, the piston cylinder volume decreases, so the oil liquid in the pan with oil discharged from the outlet of the liquid. The pump works continuously as long as the drive shaft rotates.
Q:What are the parts of a pump? How do you classify it?I just want to know
Before opening the pump suction pipes and pumps must be filled with water. Open the pump, the impeller rotating speed, which leaves the liquid together with the rotation under the action of centrifugal force, the left outside impeller injection, injection of the liquid in the pump shell gradually slow the spread of indoor speed, the pressure gradually increased, and then from the pump outlet. The outflow discharge tube. At this time, in the leaves at the center of the vacuum area of low pressure liquid was thrown to the surrounding formation there is no air and no liquid, liquid pool at the surface of the liquid under the action of atmospheric pressure, through the suction pipe into the pump, the liquid is continuously pumped up from the liquid pool is also continuous outflow from the discharge pipe.Mainly by the impeller, pump shell, pump shaft, bearings and packing sealing devices and other components
Q:What is the pump delivery? What's the difference between years and years?
1) integer integer: ~ batch. Sell ~.2) buy in bulk: ~ goods. Sell now.The exchange is, according to the duration of the contract delivery insurance premium, payment is generally in common, 5 years of insurance you every year that time, continuous call five years; general single sex 5 years or even 10 years of premium.Furthermore, the insurance premium is good or good pay period, if a single rate from the point of view, to make cheaper than single period, but considering the one-time payment of the interest cost of funds and the opportunity cost, there is no difference. While the single cross ratio advantage is mainly reflected in its flexibility. First of all, additional premium may be added to the premium. At present, additional risks can only be covered if the main risks and principal risks are covered during the payment period. The single way to buy insurance, even in the primary insurance protection period will no longer be able to purchase additional insurance new; secondly, to pay the premium can enjoy a premium waiver. If the insured in full payment period has not yet had the danger, not pay part of the premium would be exempt from the Qing dynasty. For child insurance, the premium waiver is more advantageous. If parents unfortunate accidents or illness, resulting in death or one or two, three disabled or suffering from severe illness, the insurance company will be exempted after the premium, the insurance contract shall continue to be valid; finally, to pay the premium or additional premium amount can be changed. The policy holder may adjust his insurance plan according to the change in his economic strength. In contrast, single premium has the advantage of a one-time payment more convenient.
Q:What kind of motor does the hydraulic pump need?
First count the flow: Q=dn L / minD displacement / revN RPM / minThen calculate the actual power: N=QP/ (60K) kwQ flow L / minP MPa MPaK total efficiency (usually 0.85)
Q:How to select the fire pump?
According to the water quantity form fire flow water supply system fire safety in high-rise building fire hydrant pump lift is 10L/s, accurate algorithm is to say after a simple calculation with each indoor hydrant flow is two 5L/s bolt so to get the most unfavorable point for the calculation unit to calculate the minimum requirements, with the most unfavorable point suppository pressure specifications 0.07MPa, partial loss of the most unfavorable line and the line (according to the equivalent length) and loss (according to the material resistance coefficient), and finally the pump head loss of gravity difference. But we just calculate the construction elevation difference multiplied by 110% to 120% to determine the head {there is a need to know is: conversion head (m), (kg) and MPa kg 1MPa=10 kg = 100m is the vertical water column on unit area pressure conversion
Q:Advantages and disadvantages of centrifugal pumps?
The uniform liquid no pulse phenomenon.(2) shortcomingsBefore running, the pump must be filled with liquid.For the supply of small flow, large pressure head inappropriate, inefficient and limited.Encountered imperfect design or operation is not at the time, such as milk, it is easy to produce foam, affecting the next process production.The installation is wrong. There will be "Qi tie" phenomenon.The efficiency is also lower than the reciprocating pump.The sources of knowledge are absolutely reliable!!!!
Q:Difference between pump and compressor
In the spiral case, the liquid slows down due to the gradual enlargement of the flow passage, and the part of kinetic energy is converted to static pressure, and finally flows into the exhaust pipe at higher pressure and is sent to the required place. When the liquid flows from the center of the impeller to the outer edge, a vacuum is formed at the center of the impeller. As the pressure at the upper level of the tank is greater than the pressure at the pump inlet, the liquid is continuously pressed into the impeller. Visible, as long as the impeller continues to rotate, the liquid will continue to be inhaled and discharged.The working principle of the linear pump is different from that of any other pump. It adopts the principle of magnetic suspension and the hydraulic structure of the spiral ring to realize liquid propulsion, that is, to cancel the shaft, to cancel the shaft connection, and to cancel the sealing structure of the shaft. After starting, the electric current is transformed into a magnetic field, and the magnetic field force drives the spiral ring to move, namely, the spiral ring promotes the liquid advance.Compressor (compressor), a driven fluid machine that promotes low-pressure gas as a high pressure gas, is the heart of a refrigeration system. It is of low temperature and low pressure refrigerant gas suction pipe from the suction, through the operation of the motor drives the piston to compress it after high temperature and high pressure refrigerant gas discharge pipe to the exhaust, to provide power for the refrigeration cycle, so as to realize the compression and condensation (exothermic), expansion and evaporation (endothermic) refrigeration cycle.
Q:Brief description of centrifugal pump on / off operation
Two, centrifugal pump start(1) the pump entrance valve fully open, start motor, outlet valve fully closed, fully check operation of pump.(2) when the pump outlet pressure is higher than the operation pressure, the outlet valve is gradually opened to control the flow and pressure of the pump.(3) check whether the motor current is within the rated value, such as the pump in the rated flow operation, and the motor overload should stop the pump inspection.
