Q:What are the application areas of pumps?: Water pump has different uses, different transmission liquid medium, different flow, lift range, therefore, its structure form is not the same, the material is also different, summed up, can be roughly divided into:

Q:What are the constant pressure pumps?: Constant pressure pump is also called the booster pump, the name is used for booster pump, its main purpose is water heater booster, with tall low pressure, sauna, bath and other pressure in the apartment, the lack of water pressure, solar automatic pressurization and so on.

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 are the reasons for sealing damage of centrifugal pumps?: The reasons for sealing damage of centrifugal pumps are as follows: six, the specific contents and handling methods are as follows:First, the centrifugal pump water quality is poor, containing particles.As a result of poor water quality, containing small particles and medium hydrochloride content is high, forming abrasive wear, centrifugal pump seal plane or pull the surface, resulting in groove, ring groove and so on.Treatment method: improve water pressure or medium, replace machine seal.

Q:If the calculation of the required pump flow is 45, lift 110, and the actual pump flow 100, head 125, what will happen in operation? Can I use it properly?: The air pump.The pump itself is mechanical failure.The pump outlet valve core off.Low voltage power.

Q:Centrifugal pump flow, why can be adjusted through the outlet valve? Can the flow of the reciprocating pump be adjusted in the same way?. Why: First of all, we know that pump according to the principle of work is divided into speed and volume type, centrifugal pumps are speed type, and reciprocating pumps are volume type.The centrifugal pump can adjust the flow through the outlet valve and outlet valve opening can determine the pump flow and head performance curve parameters such as specific relationship between the outlet flow and pressure can be provided by the data pump manufacturers endplate that even close the outlet valve of the pump pressure will also have a fixed value, but not allow zero flow pump operation, vibration caused by damage to the pump on the mechanical seal is not good and so easy to cavitation, set the minimum reflux line.

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 maintain and repair the booster pump of pipeline pump?: 4. install "0" ring, tighten the pump body and motor end cover with bolts. Notice that the clearance between the front cover of the impeller and the pump body is 20. 0.5 mm. The impeller inlet, the outer ring and the pump body ensure a certain running clearance.5. the disassembly order is the opposite.

Q:What is the cause of the damage of pump bearings?: First of all, know your pump model, and what is the bad bearing, in order to accurately judge for you. Because in addition to some common reasons, the structure of different pumps, bearing damage caused by the reasons are different. Otherwise it is fraught with itching shoes.

Q:No negative pressure water supply equipment, both the main pump and auxiliary pump, power is not the same, how to choose the control cabinet?: 1) microcomputer frequency conversion control cabinet2) water pump unit3) current stabilizing compensator4) vacuum suppressor5) all kinds of pipe fittings, valves and so on
