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: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:Does vacuum pump oil belong to dangerous goods?
Of flammable substances, but not included in dangerous goods!Does not belong to dangerous goods,
Q:Why does the centrifugal pump start and close first when the outlet valve is closed?
When the valve is closed off opposite is the first current to the rated current, avoid instant electricity loss of other electrical equipment caused by voltage fluctuation. At the same time, some centrifugal pump outlet check valve is not installed, the role of avoiding the pipeline caused by backflow of water pump reversal.This Regulation (or operation regulation) is generally applicable to larger power centrifugal pumps. For small power equipment, it can be used to determine whether the above operation is necessary for actual use
Q:The difference between diaphragm pumps, vacuum pumps and centrifugal pumps
The diaphragm works by changing the size of the diaphragm. When the cup is covered with an eraser and the edge is airtight, then pressing the rubber or pulling the rubber outward will make the pressure in the cup increase or decrease. Use this principle, in the pressure of an hour from a hole suction medium, when the pressure is large, from another hole extrusion medium, so as to achieve the purpose of conveying.
Q:What is the relationship between the minimum suction vacuum of a pump and the required cavitation?
Suction is allowed to pump the vacuum from the distance from the inlet, which is part of the field installation.The manufacturer of cavitation allowance is closely related to the design and process of pump. Estimation formula: cavitation allowance =10.33 meters - allow suction of -0.5 meters (safety).
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 are the differences between the sewage pump and the clean water pump?
Sewage pump is a pump and motor conjoined, and at the same time submerged into the work of pump products, and general horizontal pump or vertical sewage pump compared to the sewage pump compact structure, small footprint.The water pump is for the transport of water and physical and chemical properties similar to water and other liquids used, suitable for the industry and the city water supply and drainage, water pressure high-rise buildings, garden sprinkler, fire booster, long-distance transportation, HVAC refrigeration cycle, irrigation, bathroom, cold and hot water circulation pressurization and equipment.
Q:What is the difference between the ground pump and the pump in the commercial concrete?
What you should say here is the concrete pump.Ground pump: the pump will be placed in a position on the site, the pipeline will be sent to the construction of concrete surface,
Q:What is a gear pump for?
Gear oil pump is through a pair of parameters and the same structure of the involute gear of each other rolling meshing, the tank of low pressure oil to work can do the important parts of high pressure oil. A power unit that converts the mechanical energy of an engine into hydraulic energy. The engine is prone to the following faults during its use.
