Q:Advantages and disadvantages of canned pumps
The ordinary centrifugal pump is driven by coupling the pump impeller shaft is connected with the motor shaft, the impeller and the motor rotates while working and shielding pump is a kind of non seal pumps, pump and motor is sealed in a medium filled by pumping the pressure vessel, the pressure vessel only static seal and, by a group of wires to provide a rotating magnetic field and rotor drive. The structure eliminates the rotary shaft sealing device of the traditional centrifugal pump, so the utility model can be completely free from leakage.
Q:Hydraulic pump displacement refers to the pump shaft what?
Just as you carry a spoon to the water. How much water can you pump at once (every turn)? That's the displacement.
Q:Brief description of centrifugal pump on / off operation
(3) check whether the turning rotor is easy and flexible, check the pump body is clang or friction sound.(4) the protective cover is installed, and the shield contact.(5) clean the pump frame and do a good job of sanitation.(6) open the inlet valve, make the liquid full of pump body, open the vent valve, clean the air and close it. If the hot oil pump, it is not allowed to open the air valve exhaust, to prevent hot oil channeling spontaneous combustion, if there is a dedicated vent pipes and tanks, you can vent the pipe line air and cold oil.(7) the hot oil pump should be preheated slowly before starting. Especially in winter, the pump body and the pipe should be preheated at the same time, so that the temperature difference between the pump body and the conveying medium is below 50 centigrade.(8) the oil must be sufficiently dehydrated before being introduced into the oil pump.
Q:What is the cause of the damage of pump bearings?
In high-speed equipment, the most likely damage to bearings is high temperature.
Q:Common failure treatment of piston pump
Table 15 common troubles and treatment of hydraulic pumpsFault phenomenon, x09 cause analysis, x09 elimination method(1) the pump does not carry oil; the x091. pump does not turn x09 (1); the motor shaft does not rotate1) missed connection power supply2) electrical wiring and component failure, x09 check electrical and troubleshootx09x09 (2) motor heating trip
Q:What is the liquid pump? What are their categories? What are their strengths and weaknesses?
The air driven liquid pump adopts compressed air driving method, and has the following advantages:The pressure can be adjusted by manual pressure control valve or air control valveIt is driven by air and is especially suitable for explosion protection applicationsAble to achieve pre-set final pressureAutomatic pressure relief by pumpLong term conservation without consuming energyWhen holding pressure, medium will not overheatThe utility model has the advantages of convenient installation and low maintenance cost, and only needs to connect the gas source, the inlet pipeline and the pressure pipelineReliable operation, low maintenance cost and little noise at the time of operation
Q:Fire pump and shower pump flow head selection, high resolution.
Selection of flow head of fire pump and spray pump:1, the volume is greater than 5000 is less than 10000, the minimum water consumption of indoor fire hydrant is 10L/s
Q:Pneumatic diaphragm pump compressed air pressure is 4 kg, the discharge pressure is how big?
Have to know the ratio, pneumatic pump, if high pressure, you can have 2:1,3:1
Q:What are the starting and stopping procedures for centrifugal pumps?
The use of centrifugal pump can be divided into three steps, namely, start, run, stop.Start: you should do the following preparation before starting:(1) check the water pump equipment in good condition.(2) the bearings are filled with oil, the oil level is normal, and the oil quality is qualified(3) all the inlet valves of the centrifugal pump are opened.(4) pump water injection or vacuum pump diversion (except for flow), open the vent valve exhaust.(5) check the leakage of shaft seal. It is advisable to fill the seal with a little drop of water.(6) the motor rotates in the right direction.
Q:What's the difference between non negative pressure and variable frequency water pump?
No negative pressure is superposed pressure intelligent frequency conversion equipment, pump frequency operation is no negative pressure difference, and the variable frequency pump, variable frequency pump is advanced municipal tap water tank or pool, pump from the tank or pond water pressure to set pressure to the pressure water supply, and no negative pressure directly from water the municipal pipeline, using the original municipal 2~3 kilograms of pressure
