Q:Piston filling and peristaltic pump filling which precision is high?

These two pumps are used as a metering pump to use, so the accuracy is to be on a par with the peristaltic pump has more advantages than the piston pump is the largest energy fluid conveying there are particles, and the piston pump is smaller than the peristaltic pump pulse, so we need to choose according to the material characteristics you need to transport.

Q:What are the general water pump failure, how to repair?

Troubleshooting of water pumpFirst, the water pump does not cause water analysisThere is air in the inlet pipe and pump body(1) before the water pump is started, the water is not filled enough. Sometimes it seems that the water has been discharged from the vent hole, but the pump shaft is not rotated. The air is completely discharged, resulting in a small amount of air remaining in the inlet pipe or pump body.

Q:Does the reservoir water heater press the booster pump (high marks)?

60 liters of water storage should be able to drive two bathrooms at the same time bath! Water storage water heater generally does not need booster pump, as long as there is a little pressure, the water heater is filled with water, as long as the tap water can do. You can turn off the hot water valve and see only the amount of water in the cold water. If hot water is much smaller than cold water, it is the reason for the heater. Can you check the water mixer is normal, the one-way valve is installed in reverse.

Q:How can the submersible pump level meter be connected?

Install liquid level controller, two position liquid level sensor, controller to buy manual, wiring according to wiring diagram.

Q:Why does the centrifugal pump start and close first when the outlet valve is closed?

The contact is burned out, the bond and so on the accident, therefore closes the outlet valve, starts the electric machinery, at this time the electric machinery belongs to the no-load current movement, greatly reduces the big current impact

Q:What is the minimum continuous flow of a pump?

At'-- the allowable temperature rise of pumping medium,C- pumping medium specific heat, kj/ (kg DEG C);Ho- off dead center lift, M.Minimum continuous flow minimum continuous stable flow and minimum continuous thermal flow and the maximum value in the selection, or use the pump process, the minimum continuous flow process requirements must be greater than the minimum flow rate of the pump, otherwise it will cause the pump cavitation, vibration and noise, so that the pump parts damaged. If the minimum continuous flow the pump can not meet the minimum requirement's process, can install the bypass reflux device or reflux system in the pump pipeline, to ensure that the minimum continuous flow pump.

Q:How much water does the water ring vacuum pump run for an hour? If there is no steam separator, does the water vaporize?

For example: water storage is relatively small, it needs to reduce the temperature of the heat exchanger. If the tank is relatively large, it does not need cooling water circulation pump again when the temperature is very low, there is no need to heat exchanger. So you need to ask how much water this is not OK.In a soda separator problem:

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.

Q:Harm of air pump and pump

Minimum starting current when centrifugal pump of such a small impact on the grid but long closed operation will make the liquid in the pump to the pump overheating temperature is too high will lead to the problem of the seal to a certain temperature will cause deterioration of oil bearing bearing caused by excessive wear and even bite dead

Q:What is the pumping property of concrete?

Pumpable concrete slump is generally greater than 160mm, the mortar content is too low, the maximum aggregate size of not more than 1/3 of the diameter of the pump pipe, sending process segregation, plugging in the pump.
