Q:What is an industrial water pump?
The pump has the different uses, conveying different liquid medium, different flow rate, different lift range, therefore, its structure of course is not the same, the material is different, in general, can be divided into:1, urban water supply 2, sewage system 3, civil and construction systems 4, agricultural water conservancy system 5, power station system6. Chemical system 7, petroleum industry system 8, mine metallurgy system 9, light industry system 10, ship system
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:Working principle and diagram of axial piston pump with pressure compensation variable
The size of the outlet flow pressure compensated variable displacement pump with outlet pressure of approximately in a certain range according to the constant power curve. When the pressure oil from the main part of the channel (a), (b), (c) into the inferior vena cava (d) variable shell, oil by the channel (E) respectively into the channel (f) and (H), when the spring force is greater than the oil (f) into the lower end of the piston ring servo hydraulic thrust area when the oil liquid (H) to the chamber (g), push the variable downward movement of the piston, the pump flow increases. As for the hydraulic servo piston end thrust force ring shaped area is greater than the spring when the servo piston moves upward, blocking channels (H), the (g) (I) through the cavity of the oil cavity pressure relief, at this time, the piston moves up, the variable head angle decreases, the pump flow rate decreases.
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 kind of motor does the hydraulic pump need?
Hydraulic pump is a power component of hydraulic system. It is driven by an engine or an electric motor. It draws oil from the hydraulic tank to form a component of the pressure oil which is sent to the actuating element. Hydraulic pump according to the structure is divided into gear pumps, piston pumps, vane pumps and screw pumps.
Q:What is the pump, how to classify, mainly used in where?
Classification of pumpsAccording to the principle of division:1. displacement pumpDepending on the movement of the work parts, the volume of the work increases periodically and reduces the suction and discharge of the liquid, and the pressure of the liquid increases directly by the extrusion of the working partsAccording to the different movement of moving parts, it can be divided into two types: reciprocating pump and rotary pumpAccording to the structure of the moving parts are different: piston pump and piston pump; there are gear pumps, screw pumps, vane pumps and water ring pump
Q:Does the reservoir water heater press the booster pump (high marks)?
In addition, the water storage electric water heater has a safety valve is O.7MPa, before buying a booster pump, you can check the water inlet valve spring weakness, see the effect of water, barely even, then use it, do not buy.
Q:If you use an ordinary 15W submersible pump, put it in the tank, if the leakage, the fish will hang it?
Submersible pump even if it really leakage, it will not cause the fish electric shock. The so-called leakage is the submersible pump wire or shell broken, live parts and water contact, the most extreme test is a fire line directly into the fish tank
Q:What is a water pump coupling device?
The water pump coupling device comprises a coupler, a coupling flange, a guide rod and an upper fixing plate, wherein the contact surface of the coupling base and the coupling slide plate is provided with an annular groove, and a soft sealing gasket is tightly fixed on the groove. By adopting the structure, the coupling contact surface of the coupling slide plate and the coupling base is sealed firmly by an annular sealing groove
Q:What is a gear pump for?
Internal wear of oil pumpOil pump parts wear will cause leakage. The large leakage area between the floating axle sleeve and the end face of the gear is the main part of the inner leakage. This part of the leakage accounted for about 50%~70% of the total leakage. The pump efficiency of the gear pump is much lower than the input power when the gear pump is worn and leaked. All of its losses are converted to heat energy, which will lead to overheating of the oil pump. If the joint plane is pressed, the movement of the floating axle sleeve will cause a little wear and tear when the work is in use, so that the farm tools can be lifted slowly or can not be improved, so the floating axle sleeves must be replaced or repaired.
