Q: The suction pump has a nominal suction range of 30 metersHow deep can a well be sucked?Well, sixteen meters,: That is impossible. The suction height of the pump is caused by the centrifugal force of the vacuum. The water is sucked into the vacuum

Q: How does the centrifugal pump pump and cut the pump?: Can not be generalized, the pump is divided into many categories, centrifugal, reciprocating, screw type, diaphragm type, and so on, the starting steps of each pump is not the same. The following is the centrifugal pump and reciprocating pump to do a simple introduction. Check the items and so on.Centrifugal pump: first open the pump inlet valve, pump exhaust, and then start the motor, slowly open the outlet valve. If it is a high speed motor or multi-stage pump, open the motor before the outlet valve slightly open.Reciprocating pump: slightly open the inlet valve of the pump, fully open the outlet valve. After starting the motor, at the fully open inlet valve.Here is a brief introduction. I hope it works for you.

Q: Variable flow pumps are variable pumps: Variable input speed, the pump out of the flow is variable, it can not be said that it is variable pump.In a word。 A variable pump is a variable displacement pump.

Q: What is the pump, how to classify, mainly used in where?: 2. other classification of pumpsThe pump can be divided into two parts according to the position of the pump shaft:1) vertical pump2) horizontal pumpDivided by the number of suction ports:1) single suction pump (single suction pump);2) double suction pump (double, suction, pump)According to the prime mover of the drive pump:1) electric pumps2) steam turbine pump3) diesel engine pump[other details]

Q: Water pump can not be pumped out, how to maintain water?: Severe vibration of water pumpIt is possible that the rotor is unbalanced, or the coupling is not good, the bearing is worn and bent, and some parts may be loosened and broken. They can be adjusted, repaired, strengthened or replaced separately.

Q: How is the pump level of submersible sewage pump determined?: Below the top elevation of the sump, 200 is the warning water levelBut note: 1, the effective volume of the sump meets the requirements. 2, the pump should have enough submerged water level

Q: Bolus dosage of infusion pumpWhat is the purpose of the pill dose control in the special safety standard for infusion pumps? If the risk is not properly controlled, what is the degree of risk? And how can the open infusion pump be used in this regard?: Four) release bolus dosage method can use automatic release and manual release two ways, the key is to alarm after the infusion must be stopped(five) any kind of pill dose release are not restricted to replace the pill. The total dose limit for in pipe blockage after pill agglomeration process will remove blocking accident, this time will be the rapid infusion of pill dose concentration into the patient's blood, if the total dose pill does not get test and limit, rapid infusion of this accident it may have unimaginable consequences.(six) supplies open type infusion pump overflow on the domestic market for pill characteristic parameters of consumables simply without testing and limitation. Therefore, the risk of accidental pill has become one of the residual risk of open type infusion pump supplies the most deadly.

Q: What is the liquid pump? What are their categories? What are their strengths and weaknesses?: The liquid pump can be filled with oil, water and chemical medium. The gas drive range of the liquid pump is 1 to 10bar (14.5-145psi). The bottom piston is controlled by a two position four pass pilot valve.

Q: What is the pumping property of concrete?: Under a certain pump pressure, the farther or higher the concrete can deliver, the lower the probability of clogging, the better the concrete pumping performance.

Q: Hydraulic pump displacement refers to the pump shaft what?: You can see the sign of your hydraulic pump. There will be a displacement **ml/r in the sign of the hydraulic pump (r stands for every turn, ML is milliliter)
