Deep well submersible pump installation and use of the method

1. Deep well submersible pump acceptance: user acceptance check carefully to the logistics company delivery cable sheath have damaged. Water pump with and without fracture.

2. Handling, loading and unloading car need to be careful, so as not to damage the concentricity of the unit or touch broken cable insulation.

3. A complete set of unit under well before the inspection steps: a. open mesh, even with all pry bar shaft should be flexible rotation, B put add fresh water, the electric pump shaft connected cable joint, with water immersion, joint rock joint to ground resistance measurement (single joint insulation resistance) of water value is not less than 500 ohms. C. put using suitable container to pump the water pump set of export with detergent water, at the same time point to move a little bit about the motor start button to see the pump steering, time shall not be more than 2 seconds, completes the sequential markers.

4. When pump fission transportation field assembly steps: a. before installation will put the motor to the vertical, open porosity and water injection hole, pay attention to must open the both water block, add fresh water to water plugging and water plugging is tightened, observe the motor if there is leakage phenomenon, if there is leakage phenomenon must not well, the reason may is the transport process of knock against, should contact the agent or manufacturer's talk things over solve, until not leak (10 ~ 15 minutes). And then shake test motor insulation resistance, the value of no less than 50 ohms. B. bandage cable joint, wrapped after try the steering motor, motor turns to the direction of the arrow marked on the pump are consistent, and sequential markers.

5. Submersible deep-well pump inspection when fission

A. on the pump shell is removed to show the top of the impeller, b. flexible c. rotating impeller by hand to see if the pump shaft direction pull the seven total amount up to observe the impeller impeller (QJ pump commonly 4 to 6 mm) d. install connecting shaft and motor into one to make the motor shaft head and pump shaft head of tight no cracks are allowed. E. jumped up and down the impeller clearance, should be in the middle of the amount of total channeling location (allowable deviation plus or minus 0.5 mm). F. when the deviation is greater than 0.5 mm in adjustment gasket to the middle position in hand rotating impeller should be flexible. G. then even the axis is the top wire holes, tighten the top wire installed on the shell. H. again even with all pry bar should be flexible rotation for a week and put shaft device. Then pretend to filter and convenient slot on the box.

6. Under the deep well submersible pump well, the well before the rope hanging a in units of the same length logs or steel pipe (diameter) unit is equal to the largest diameter test tube well is upright. In order to avoid the well stuck units.

(especially new well first pump, mine do not need this step).

7. The cable tie, cable to use insulation cable tie binding to raise water pipes, don't use metal wire.

8. Control of the unit and start: control equipment selection. Motor power by 1.2-1.4 = power control cabinet. Control cabinet to be lack of phase, overload, over current short circuit protection, etc. Started well after the installation of commissioning, startup time according to the difference of motor power, master between 10 to 25 seconds, high-power motor startup time should be relatively long, check whether the current overload, whether the three phase current balance and recorded. As the basis of warranty and feedback manufacturer.

9. Overload, short circuit, over current, lack of phase, debugging sensitivity: this step is very important, please installation personnel serious debugging.
