Q:Why is the submersible pump tripped on an electrical switch?There is no electrical leakage protection, directly connected to the circuit breaker, and when the switch on, the circuit breaker jumpedI checked the line is good, the pump did not break down, is not the water pump?: There should be the following reasons: 1) the setting value of the trip switch is too small, and the operating current of the submersible pump exceeds its setting value, and the switch is tripped

Q:Why can't the centrifugal pump pump the vacuum?: Condition:The pump shell must be filled with liquid under certain installation height and running without leakage.What is the phenomenon of centrifugal pump? What harm does it have? How to eliminate?)

Q:Metering pumps related matters: Rotate to stroke length 100% position. This allows the kit to rotate to the back of the drain hole and align the bottom of the pump. Adjust the hydraulic end and diaphragm to the proper position during the pump operation.The duration of the pulse may not be long enough for the reaction time. With respect to the standard pulse width 80msec, the flow monitor pulse width expansion can be activated, increasing the pulse width to 300msec. Activate the smart switch, remove the cover fixed circuit board, remove the jumper X-1. This activates the extended function and allows more time before the failure instructions.Metering pump installed from the exhaust pump head, the use of self suction liquid imbibition. Keep the suction line as short as possible.

Q:How about the depreciation of vacuum pumps?: (five) electronic equipment, for 3 years.The depreciation period of a vacuum pump can be calculated for 5 years. The expected residual rate is generally 5%, or it can be estimated by itself.

Q:Attention should be paid to the use of pumps?: To carefully check whether there is a crack impeller, impeller fixed in the bearings are loose, if there are cracks and loose, hungry phenomenon should be promptly repaired, if the pump impeller above the soil should also be cleaned

Q:Roots pump and dry pumpRecently involved in the work of the vacuum pump, don't understand this, is a ads602 vacuum pump, composed of roots pump and dry pump, is pre pumped to the 500mtorr equipment, the main pumping vacuum continues to 10mtorr, where the roots pump and dry pumps must be used? What role they play respectively. The so-called dry pump? Is refers to one kind of the pump, the pump is many dry pump? Also do not understand how the work of automatic switching system for pre pumping, the main pump, pump work alone did not connect system ah (of course there are even a butterfly) teach?: Different working conditions, our company does dry claw pump alone can also achieve the vacuum of 133 PA.

Q:What is the Rhodes pump?: Work principle editorRoots-type pump is a vacuum pump without internal compression, usually compression ratio is very low, so high and medium vacuum pumps need pre pump.A vacuum pump for pumping air by pumping a gas by the simultaneous rotation of a pair of lobed rotors in a pump cavity and a reverse rotation.Roots vacuum pump is a mechanical vacuum pump with a pair of synchronous and high-speed rotating sole shaped rotors. The pump can not be drawn out separately. The front stage needs to be equipped with an oil seal and a water ring, etc. it can be discharged directly into the atmosphere.

Q:What is the function of the heating pump system for the water pump design?: Will cause some of the internal friction gap disappeared, the coupling center damage. In this case, starting the pump inevitably results in vibration, friction, etc.

Q:What is double hydraulic pump?: Two hydraulic pumps installed on one shaft can be connected to increase output flow, and can also be connected to increase output pressure. See how the demand is. The system can change the mode of application at any time.

Q:What are the general water pump failure, how to repair?: Two, pump speed is low(1) human factors. Some users because of original motor damage, may be accompanied by another motor, resulting in a flow of small, low head or even the consequences of Sheung shui.(2) the mechanical failure of the pump itself. Impeller and pump shaft fastening nut loose or deformation of the pump shaft bending, resulting in multi impeller, directly with the pump body friction, or bearing damage, are likely to reduce the pump speed.(3) the maintenance of the power machine is not working. The motor is lost because of winding burn, the change of winding number, wire diameter, wiring method, or failure in maintenance can not change the pump speed.
