Deep well submersible water pumps installation advices

Deep well pump, submersible pump motor and pump water machine straight league one into the water, it is suitable for the extraction of groundwater from a deep well, can also be used for rivers, reservoirs, canals and other water projects: it is mainly used for farmland irrigation and plateau mountainous area with water, can also cities, factories, railways, mines, construction site water supply and drainage.

Are in deep well submersible pump installation of generating unit and the matters needing attention for description of the following three points: one, deep well submersible pump installation instructions: 1. The pump inlet must be in the dynamic water level 1 m, but not more than static level the diving depth of 70 meters, the motor bottom hole at least 1 m below.2. The power rating xiao yu or equal to 15 kw motor adopts full pressure start.3. The power rating is more than 15 kw, step-down starting motor adopted.4. Using the environment must meet the prescribed conditions.

Second, deep well submersible pump installation preparation: 1. The first check the diameter of the well, still water depth and the power supply system is in line with the conditions of use.2. Check whether the electric pump rotation is flexible, should have no card dead center, the repackaging of motors and pumps used coupling connection, attention to tighten the top.3. Open the exhaust and injection screw, the motor lumen fresh water injection, pay attention to prevent false full and plug.

There should be no slack phenomenon.4. The motor insulation is measured with 500 v megohmmeter, shall be not less than 150 megabytes.5. Should prepare the corresponding hoisting tools, such as tripod, chain hoist, etc.6. Installed protection switch and start the equipment, the instantaneous start motor, whether the turning of the motor and to sign the same, if on the contrary, switching power supply can be any two connectors, then good convenient between the plate and water networks, prepare well.

In steering motor and pump connection, must from the pump outlet into the water, the water from the inlet throttling can start. Three, the installation of the deep well pump: 1. The first installed in the outlet of the pump to pump pipe section, and plywood clamp, sling fell into the well, make the plywood is located on the spring.2. With a pair of plywood clamp another delivery.

Then lift and fall into the connect pipe flange and rubber gasket, when screw must be diagonal simultaneously. Rose chain hoist first pay splint, decreased pump pipe clamp and fell on him. Repeated in sequence for installation, under the well, until finish all outfit, put a manhole cover, the last pay plywood not remove it on manhole covers.3. Install the bent pipe, gate valve, outlet, and the corresponding rubber gasket seal.4. The cable is fixed on the water pipe flange of the slots, each firm the rope fixed well, the well process need to be careful, must not be damaged cable.

Under 5. If you have stuck phenomenon in the process of pump, the idea to overcome card points, not to force the pump, so as to avoid stuck.6. Installation personnel are strictly prohibited under operation.7. Protection switch and boot device should be installed in the user panel, panel with voltmeter, ammeter, lights, and placed in the appropriate location inside the room.8. Use "with wire from the motor base to connect pump pipe bundle" force protection measures, to prevent accidents.
