1. Stainless steel deep-well pump before the installation of inspection and preparation
(1) Check whether the pump is in compliance with the conditions of use of the pump, that is, the diameter of the well, the vertical and the quality of the wellbore, the static water level, the moving water level, the water discharge quantity and the water quality condition. If the conditions are not met, the pump must not be pumped down .
(2) Check the power supply equipment and power supply lines can ensure the normal operation of the pump.
(3) whether the power supply voltage and frequency meet the conditions of use.
(4) familiar with the installation instructions, the new drilling wells must be washed well, remove the mud after the water before they can install the submersible pump.
(5) check the electrical wiring, control and protection devices are reasonable and safe and reliable.
(6) ready to use a variety of installation tools, erected tripod and chain (or other lifting tools) to be safe, reliable, easy to use.
2. Stainless steel deep-well pump installation
(1) pump unloading one drainage network, and then open the water injection and release holes bolts to the motor cavity filled with clean water, be sure to fill, to prevent false full. And check whether the Ministry of motor leakage. Found that leakage should be adjusted according to the location of the pads on the tight bolts.
(2) carefully check whether the cable and connector bruises or damage, and found a timely packet holes.
(3) measured with a 500-megohm winding insulation resistance of not less than l50 megohm.
(4) Install the protective switch and starting equipment, and check whether the motor is filled with water and then tighten the water injection, put the bolt holes, and then a good line protection board, drainage network ready to go down.
(5) in the stainless steel deep-well pump outlet to install a short water pipe section, and clamped with a clamp down into the well, so that the splint sits on the well.
(6) and then a pair of clamping plate clamp another section of the water pipe, and then hoisted down and short water pipe flange connection. Raise the lifting chain to remove the first clamping plate, so that the pump tube down the well is located on the well stage, followed by repeated installation, go down, until all Bahrain, the last section of the plywood will not unload the pump fixed on the wellhead.
(7) Finally put the covers, elbow, gate valve and other water pipes.
(8) to connect the flange each time to add pads, align the rear fastening screws to diagonal direction at the same time tighten to prevent skew leaking.
(9) cable to be fixed in the water pipe flange groove, each section are tied with a rope fixed, down the process to be careful, the cable can not be used when the sling, not to bruise the cable.
(10) under the process of the pump stuck phenomenon, to overcome the card point, can not force the next pump to avoid stuck.
(11) large wells and other wells when the installation is prohibited.
(12) protective switch and starter equipment should be equipped with voltage, current meter, indicator light, and installed in the distribution board, on the well around the appropriate location.
3. Stainless steel deep-well pump start
(1) with 500 volt megger to measure the motor winding resistance to ground insulation resistance of not less than 5 megohm.
(2) Check the three-phase power lines, voltage compliance, a variety of instruments, protective equipment and wiring is correct before closing start.
(3) after starting to observe the current, voltage, whether the provisions of the scope of the operation of the sound with or without abnormal vibration phenomenon occurs, if not normal should promptly identify the cause of treatment.
4. Stainless steel deep-well pump test steering
In order to determine the correct direction of rotation of the motor, the pump should be in the closed state, according to two directions. Through the exchange of three
Any two phases of the phase power supply change the direction of rotation. Rotation direction is different, the pressure gauge readings are also different. Pressure higher direction
Is the correct direction of rotation. It is also possible to determine the direction of rotation from the magnitude of the flow rate when the valve is open and the correct direction of rotation in the direction of the larger flow rate.
5. Stainless steel deep-well pump stop
(1) Turn off the switch to stop, and then start to wait for 5 minutes or more time to prevent the motor temperature is too high, the best cut off after shutdown.
(2) protection switch shall not be disabled, or increase the fuse with aluminum wire copper wire is wrong.
(3) stainless steel submersible pump continuous downtime shall not exceed 14 days, otherwise, water impurities, precipitation in the bearing and impeller clearance, or even block the pump shaft. If the working environment requires more than 14 days of downtime, should be at least once every 14 days, boot, run 5 minutes, to ensure that the unit at any time boot.
(1) Check whether the pump is in compliance with the conditions of use of the pump, that is, the diameter of the well, the vertical and the quality of the wellbore, the static water level, the moving water level, the water discharge quantity and the water quality condition. If the conditions are not met, the pump must not be pumped down .
