Precautions When Using Electric Pump
Install the leakage protector
When working underwater, the equipment is easy to leak current, causing losses and even dangerous accidents. If a protector is installed, as long as the leakage value exceeds the allowable weak current value, the device will automatically cut off the power supply to avoid waste and ensure safety.
Avoid frequent switching
Do not turn the pump on and off repeatedly for a short period, as the electric pump will backflow when stopped. If you turn it on immediately, the motor will start the load, causing too much starting current and burning out the windings. Repeated switching can also burn submersible pump motor windings due to the large charge flow at startup.
Do not let the submersible pump work for a long time
In order to prevent the electric pump from working under high load for a long time, try not to pump water when there is too much sand, and always observe whether the current value is within the value range specified on the nameplate. If the value is found to be too large, it should be turned off to check. In addition, the dehydration operation time of the electric pump should not be too long to prevent the motor from overheating and burning.
The rotation direction of the motor should be correct
The direction of rotation of the motor should be clear. There are many types of pumps that can pump water during either forward or reverse rotation. However, during reverse rotation, there is less water output but higher current flow. If the reverse time is too long, the motor windings will be damaged.

What if the water pump doesn't discharge water?
In our daily pump maintenance process, many users will encounter the problem that the pump does not discharge water. We all know that if there is air in the inlet pipe and pump body, the pump will not discharge water. Before the pump is started, it is not filled with enough water. Sometimes it seems that the filled water has overflowed from the vent hole, but the air is completely discharged without rotating the pump shaft, resulting in a little air remaining in the inlet pipe or pump body. The horizontal section of the water inlet pipe in contact with the water pump shall apply a downward slope of more than 0.5% against the water flow direction, and the end connecting the water pump inlet shall be high, not completely horizontal. If it tilts upward, air will remain in the water inlet pipe, reducing the vacuum in the water pipe and water pump and affecting water absorption.
In other words, if the packing of the pump has been worn out due to long-term use or the packing has been pressed too loose, causing a large amount of water to be ejected from the gap between the packing and the pump shaft sleeve, the result is that the external air enters the inside of the pump from these gaps, affecting the water lifting. Due to long-term potential underwater, the water inlet pipe has holes due to pipe wall corrosion, and the water surface continues to decline after the pump works. When these holes emerge from the water surface, air enters the civil water inlet pipe from the holes. Cracks appear at the elbow of the water inlet pipe, and there is a small gap between the water inlet pipe and the water pump, which may make air enter the water inlet pipe.
In addition, the low speed of the water pump will also cause the water pump not to flow out. If it is human factors. Due to the damage to the original motor, some users randomly equipped another motor to drive, resulting in the consequences of small flow, low lift, and even no water supply. Moreover, it is the mechanical failure of the water pump itself. The loose fastening nut between the impeller and the pump shaft or the deformation and bending of the pump shaft may cause the impeller to move more, direct friction with the pump body, or bearing damage, which may reduce the speed of the water pump. The maintenance of the power machine is not effective. The motor loses excitation due to the burnout of the winding, the change of the winding turns, wire diameter, and wiring method during maintenance, or the failure in maintenance is not eliminated, which will also change the speed of the water pump.

Application field
① In the production of chemical and petroleum sectors, most of the raw materials, semi-finished products and finished products are liquids, and the production of semi-finished and finished raw materials into semi-finished products and finished products needs to go through complex technological processes. During these processes, pumps play a role in transporting liquids and providing pressure flow for chemical reactions. In addition, in many installations, pumps are used to adjust the temperature.
② In agricultural production, pumps are the main irrigation and drainage machinery. my country's rural areas are vast, and a large number of pumps are needed in rural areas every year. Generally speaking, agricultural pumps account for more than half of the total output of pumps.Pumps are also the most used equipment in the mining and metallurgical industries. The mine needs to be drained by pumps, and in the process of beneficiation, smelting and rolling, pumps are needed to supply water.
③ In the power sector, nuclear power plants need nuclear main pumps, secondary pumps, and tertiary pumps, and thermal power plants need a large number of boiler feed pumps, condensate pumps, oil and gas mixing pumps, circulating pumps, and ash pumps.
④ In national defense construction, the adjustment of aircraft flaps, tail rudders and landing gear, the rotation of warships and tank turrets, and the ups and downs of submarines all require pumps. High pressure and radioactive liquid, and some also require the pump without any leakage.
⑤ In short, whether it is aircraft, rockets, tanks, submarines, drilling, mining, trains, ships, or everyday life, pumps are needed everywhere, and pumps are running everywhere. That's why the pump is listed as a general-purpose machine, which is a major product in the machinery industry.
⑥ Electric pumps, i.e. pumps driven by electricity. The electric pump is composed of a pump body, a water lift pipe, a pump base, a submersible motor (including cables) and a starting protection de
