Q:Why does the water pump leak?
Two reasons.One is that the gap between the bearings becomes larger. Damage the water seal. One is the aging of water seal.
Q:Submersible pump reverse impact on the pump
Water pump is easy to burn out.Submersible pump is an important equipment for deep well water extraction. When in use, the whole unit dives into the water. The extraction of groundwater to the surface is water, mine rescue, industrial cooling, irrigation, water lifting, ship ballast, also can be used in fountain landscape, hot water submersible pump for hot spring bath, but also can be applied to the extraction of groundwater from wells, can also be used in rivers, reservoirs, canals and other water projects. Mainly used for irrigation and high mountain areas, drinking water, but also for the central air conditioning cooling, heat pump, cooling pump unit, city, factories, mines, railways, construction site drainage use. The general flow can be achieved (5m per hour, fand fand ~650m) head can reach 10-550 meters.There are several kinds of electric submersible pump, in line package is oil immersed and water invasion there is dry must first read the instructions before use, cannot be wrong, not long before use, must have to make the impeller turn, or because of long time card dead burning.Before the pump is opened, the suction pipe and pump must be filled with liquid. Open the pump, the impeller rotating speed, which leaves the liquid together with the rotation under the action of centrifugal force, the left outside impeller injection, injection of the liquid in the pump shell gradually slow the spread of indoor speed, the pressure gradually increased, and then from the pump outlet, the outflow discharge tube.At this time, in the leaves at the center of the vacuum area of low pressure liquid was thrown to the surrounding formation there is no air and no liquid, liquid pool at the surface of the liquid under the action of atmospheric pressure, through the suction pipe into the pump, the liquid is continuously pumped up from the liquid pool is also continuously from the outflow discharge tube.
Q:What's the water pump?
Cooling water pumpDetermination of water replenishing pump1) the hourly flow is 4%~5% and the total water quantity is.2) the lift is the replenishment point and the pressure is plus 30~50 kPa.3] water pump to overcome the pressure of the replenishment point and the pressure difference between the make-up water tank, during which the pipeline is not long, you can ignore its resistance4) open system replenishment, no replenishment pump
Q:How do I calculate the power of the pump?
A 15kw pump, know how to calculate the head pumping water for an hour (if the head is 10 meters)Lift: MFlow rate: kg / sec (general water pump is cubic / hour, if 10 cubic hour / hour: 2.7 kg / sec)Efficiency: average 60%15000/102*0.6=88 kilograms per second88/10=8.8 kg / sec8.8*3600=31680 kg / h=31.6 cubic / hour
Q:Water pump motor overload
If the power line is too long or too small, power line is too long or too small will cause excessive current. Valve shut down certainly affect the flow. When the valve is in the semi open state, the water pump out of the water flow down, the power to reduce, so the current drops.
Q:The wiper pump is broken. How much will it cost to fix it?
This can not be repaired, can only be replaced, change a thirty or forty
Q:Why is the minimum liquid temperature allowed at 2 DEG C instead of 0?
It freezes at 0 degrees, and the pump runs and gets stuck.
Q:The water burst how to repair?
This is used by welding and making AB calls
Q:Safety head of water pump?
Pump selection should pay attention to the following points: (1) to meet the maximum load conditions, should try to reduce the waste of energy; (2) rational use of high efficiency section of the pump; (3) using the same type pump as much as possible, the type of neat, standby each other; (4) to the selection of large pump according to the actual situation, but also should consider taking into account the size, flexible deployment; (5) lack of H value changes, different types of collocation is optional pump operation. (6) to ensure the water conditions, take care of basic level, reduce the pumping depth; (7) consider the standby unit necessary; (8) check the fire with water; (9) considering the development, implementation of the combination of short and long term; (10) to the selection of water pump type local mass production.
Q:Why is the water pump usually used multi-stage pumps, while the circulating pump is usually a single-stage pump?
Mainly determined by the function of the water supply pump and the circulation pump.Replenishment pump is mainly to supplement the loss of the system, so the general flow is smaller, larger head, single pump water model in a small flow situation, many are not up to the required head, can only use multi-stage pumps.Circulating pumps are generally large flow, low lift, heavy efficiency, economic operation, and hydraulic model point of view, are single-stage pumps more appropriate, especially single stage double suction pump.
