installation of submersible water well pump unit

Installation of submersible water well pump unit:
1. submersible water well pump installation instructions
(1) water pump inlet must be in the moving water level 1 meter, but the depth of diving should not exceed the water level about 70 meters, the motor from the bottom of the bottom of the least 1 meters. (2) rated power is small or equal to 15kw (power supply allows 25kw) motor with full pressure start.
(3) rated power greater than 15kw, the motor uses a buck to start.
(4) the use of the environment must meet the required conditions.
2. Preparation of submersible water well pump before installation
(1) first check the diameter of the wells, the depth of the water and the power supply system is in line with the conditions of use.
(2) check the pump is flexible, should be no stuck, sub-installed motor and pump coupling coupling, pay attention to tighten the top wire.
(3) open the exhaust and water plug, to the motor cavity filled with water, pay attention to prevent the full, good on the plug. There should be no leakage.
(4) measuring the motor insulation with a 500 volt megger, shall not be less than 150 ohms.
(5) should be equipped with the corresponding lifting tools, such as tripod, hanging chain and so on.
(6) Install the protective switch and start the device, instantly start the motor (no more than 1 second), see whether the steering of the motor and turn the same sign, if the contrary, the exchange of power can be any two joints, Water net, ready to go down. When the motor is connected to the pump, it is necessary to pour water from the pump outlet to start before the water flows out of the water.
3. submersible water well pump installation
(1) first in the pump outlet to install a pump tube section, and clamped with a splint, hanging into the well, so that the splint is located on the well platform.
(2) and then a pair of splint clamping the other section of the water pipe. And then lift, down and then connected with the water pipe flange pads, screwing the screw must be diagonal at the same time. Lift the chain to remove the first plywood, so that the pump down the splint and fall on the well. Followed by repeated installation, down, until all the equipment, put the covers, the last one does not disassemble the splint on the cover.
(3) installation of elbow, gate valve, outlet, etc., and add the appropriate rubber seal.
(4) cable to be fixed in the groove on the water pipe flange, no section with a rope fixed, go down the process to be careful not to bump the cable.
(5) under the pump if the phenomenon of stuck, to think of customer service card points, can not force the next pump, so as not to stuck.
(6) installation is strictly prohibited personnel down the work.
(7) protection switch and start-up equipment should be installed in the user's power supply board, the switchboard with a voltmeter, ammeter, light, and placed in the appropriate position in the well.
(8) the use of "wire from the motor base to the pump tube tied" forcibly protective measures to prevent accidents other than.
