Submersible pumps are different from ordinary pumps
Ordinary pump work on the ground, while the submersible pump works in the water. It is because the submersible pump work environment, so the requirements of submersible pump is much higher than the ordinary pump. The most important point, submersible pump corrosive problems, used to deal with submersible pumps in a timely manner, you can use the third device to dry the submersible pump. There is a little different, submersible pump before running to fill the water, because only the submersible pump will produce centripetal force, centripetal force will promote the water.

Submersible pump debugging steps
A. Overload overcurrent debugging: the thermal relay current adjustment knob, slowly to less than the actual working current direction of rotation, each rotation a little scale, interval 2-5 minutes or so, until the thermal relay action unit to stop working so far. And then reverse the rotation can be a little scale;
B. Phase loss sensitivity debugging: the unit to start again, and one by one off the unit knife switch fuse, so that the unit in two-phase electrical work. Observe whether the thermal relay can cut off the control power within 5 seconds;
C. Short-circuit test: This step is usually protected by the air switch of the power supply system. Generally do not field test (more dangerous) requires the power supply system must be equipped with air switch (air switch model preferred DW10 type, selected DZ type).

Performance requirements for stainless steel deep well pumps
The submersible pump is a widely used tool of drainage, the medium can be classified into water submersible pump, submersible pump and water submersible sewage pump three, from the installation method, generally divided into vertical, inclined and horizontal three, widely used in production and life in general there are 304 stainless steel deep well pump, 316 stainless steel pump, high flow and high lift submersible pump, large flow and low lift submersible pump etc..
Different application areas for submersible pumps are different, but generally speaking, stainless steel deep well pump in the performance of universal standards. Stainless steel deep well pump to run continuously for a long time, this requires that the design parameters of the pump, the design of suitable flow and lift, and ensure the pump impeller does not produce gas turbidity in various operating conditions, to ensure the pump abnormal vibrations in any operating conditions. The general water pump to work continuously, so the pipe pressure is very large, sometimes may be deformation, thrust and torque which requires the supplier to provide the power plant pipeline of pump interface allowed tolerance range.
With the development of industry, more and more modern city construction, the requirements of these materials is taller than before, in the selection of submersible pump should pay attention to the performance requirements of stainless steel pump, fully understand in order to achieve high efficiency, improve production speed and quality of life.

Submersible pump start device
Simple submersible pump also has a lot of species and shape, it is also a fashionable object. Submersible pump start device mainly Y-type star delta starter start device, direct start device, auto-step-down start device, variable frequency step-down device these four. So what about their function? Then look at your introduction below.
1.Y-type star delta buck starting device
This is a large power submersible pump, can be run in the overload, stall and undervoltage and other abnormal operating conditions to protect, can also be based on changes in pressure or level of automatic control of submersible pump operation, and Equipped with stator winding overheating, bearing overheating, motor or oil indoor water and other special protection.
2.Direct start device
It is used for low-power submersible motor and submersible pump, starting device by the contactor, relays and other components, can be equipped with stator winding overheating protection.
3.Auto-step-down start device
This device can be on the submersible motor and submersible pump step-down start, starting device in addition to contactors, relays and other components, the control panel and equipped with a self-lotus transformer. Its function to the first two devices are equipped with the function.
4.Variable frequency step-down start device
Its function is that the water supply system can automatically adjust the system water supply pressure, so that the water supply pressure to maintain a constant, to avoid the water pressure fluctuations. Using the inverter device soft start, eliminating the start of the impact of the current, extending the service life of the device. The water supply system will automatically adjust the speed of the submersible pump and the number of running units according to the set pressure, so that the water supply system can be operated in the energy efficient optimization state.

Specific method of centrifugal pump filled with water and exhaust
The pipe section outside the pump outlet is the pressure pipe section. The pressure pipe section is equipped with a pressure gauge to measure the pump outlet pressure. The ball check valve is used to prevent liquid backflow in the water pipe section. Generally every time before pumping the pump must be filled with water, commonly known as water diversion. In addition. A drain should also be installed to direct the leaked water from the packing lid to the drain. Sometimes, for the need for anti-vibration, the pump at the entrance of the general selection of K-ST-type flexible rubber joints. Because the centrifugal pump is the impeller to pump the water out of the pump after the formation of a vacuum and water, so in addition to the impeller immersed in water centrifugal pump and self-priming pump, the valve used to adjust the size of the flow. In addition, installed in the heating, air conditioning system on the pump also need to install the thermometer. Panda water pump there are two ways: First, directly to the pump water (at this time should open the vent hole drain pump air); Second, the pump gas to go, to establish a certain degree of vacuum (at this time to close the outlet Gate valve), the introduction of water to go. The following describes several centrifugal pump water and gas exhaust method.
1.With hand pressure pump water. Some pumps come with hand pressure pumps and can also be purchased or self-made small hand pump installed in the inlet must be installed gate valve. After the valve closed, first with a small amount of water filled with water pressure machine for water, and other hand pump after the water, said the pump has been filled with water, you can boot work.
2.The use of vacuum equipment exhaust water. Centrifugal pump from the exhaust and vacuum pump pumping negative pressure exhaust is the same reason, so the use of water ring vacuum pump exhaust to achieve the role of water.
3.Filled with water in the inlet and outlet installed valve . This method is installed a valve in the water pipe, connected to the water pipe to the pump filled with water.

Submersible pump clear hole technology
In submersible pump design, clear hole technology is a very important work. How to master its clear hole technology, the following for everyone to elaborate:
Submersible pump clear hole technology mainly draws on the gas lift type reverse rotation rotary drilling mud removal system. Due to the use of impact drilling machine into the hole, so the water pile mud requirements are not very high, are piling the process of self-made mud, but also because after the hole has been used to dig the large diameter particles have been excluded, so you can do the mud sucking jobs. The depth of the hose in the catheter connected to the conduit should be greater than 1.5 times the height of the head in the borehole to the mouth, and the duct is about 20-30 cm from the bottom of the hole.
Through the submersible pump on the vacuum suction of the mud, reducing the water level within the catheter, because the catheter and the water level within the pile to form a connector, so that the water quickly from the bottom of the catheter flock to the catheter, so that through the catheter hole on the pile bottom layer Upward pressure, the bottom of the pile into the catheter into the catheter and then into the rubber tube, and finally discharged by the submersible pump.

How to extend the use of submersible pumps
Pump impeller and drive the impeller motor are sneaking into the water to work in a submersible pump, submersible pump is divided into deep well and operating surface.
In the use of submersible pumps should be high-definition motor rotation direction, and now there are many types of submersible pump forward and reverse are likely to water, but the reverse of the water is small, the current is large, reverse the time Long after the damage will be the corresponding motor winding. Submersible pump the mortgage power supply line is relatively long, 
the line terminal voltage is too low is often. When the voltage and the line voltage is lower than the corresponding voltage, the submersible pump motor speed decreases, when less than the required speed, start the centrifugal switch will be other, resulting in a long time to start the winding power and heat Burn the corresponding windings and capacitors. The voltage is too high will burn out, in the operation must be observed at any time the corresponding power supply voltage value, abnormal after the motor should immediately stop rotating, find out the cause and troubleshooting.
