Heavy duty bearings with high thrust capacity Heavy duty bearings provides the option to revolve both sides, has the capacity to carry high thrust load. Water lubricated radial carbon bearings Radial carbon bearings, which have channels in its structure that makes it possible to get lubricated by water easily, provides precise bearing of rotor shaft at up and down. Chrome-plated bearing collet Chrome-plated and precisely machined bearing collets which are located in the radial bearings operating area, have great importance for bearing the rotor. Mechanical sealing system for high sand resistance and degree of protection: IP68 Although mechanical seal is optionally used by other companies, it is always used by Vansan as a standard, to prevent sand and other particles to get in motors to provide long bearing life. Practical and easy-to-mount output power cable Connection of the power cable to body is made practically by cable seal and seal cover. Power cables can be changed easily without any damage. Pressure balancing checkvalve Pressure balancing checkvalve controls the pressure changes inside the motor. When the pressure increases, it throw water out of the motor.when the pressure drops, it filtrates the water inside well and gets it inside the motor by the help of this checkvalve to balance the pressure inside. That s why pressure differences inside motor never causes membrane under motor to blow up.

PT00 Overheating protection By connecting the PT00 thermal sensors to the slot that is standardly placed on upper bearing body, motor temperature values can be easily measured. Up-Thrust ring Provides safe operation conditions for motor by absorbing Up-Thrust loads with it s machined surface and water channels on it. Cable connection Preventing the water inside the motor to run through the cable and reach connection parts of power cables by specially designed cable seals. Adjustment screw Standard shaft height can be precisely adjusted by the adjustment screw on the thrust bearing base. Membrane Membrane minimizes the expansion pressure that is caused by heating of cooling water s inside the motor Slinger (sand guard) Slinger helps to prevent the sand inside the water of the well entering in mechanical seal and through mechanical seal to inside of the motor.

Copper Pipe 5 cm 5 cm Rubber tape 5 cm 5 cm PVC tape Power Cable Connection Connection of the power cable that will be used along the well and until the control panel with the power cable on the motor must be done very carefully and by the professionals only. Unless the insulation after the connection is well done, short circuit might happen when the connection area is in the water. Insulation of each cable should be stripped only as far as necessary to provide room for a stake type connector. Each individual joint should be taped with pvc tape, using two layers by wrapping tightly for eliminating airspaces as much as possible. Total thickness of tape should be no less than the thickness of the cable insulation in order to prevent the smashing of the cables when the pump is lowered in the well. Use Cooling Jacket Cooling of submersible motors is provided with the flow of the water around it. That s why water flow around motors has vital importance during submersible pump installation. This flow rate depends on diameter and power of motor. Most important factor of submersible motors long service life is that the motor has to be cooled well. Required flow velocity around the motor is given in the table below for motors being cooled well enough. If the motor will be installed in an open body of water (i.e pool) or diameter of the well is much bigger than the diameter of the motor, Flow Inducer Sleeve must be used to provide the flow velocities that are given in the table below, around the motor.

Insulation Resistance Test All Vansan motors are applied insulation test under 3.000 V before shipment. Motors which have at least.000 megaohm test result are shipped. Insulation test results should be controlled before the installation and after connecting power cables as it is explanied below. Meger tester s one probe should be touched to motor body and other probe should be touched to tip of each power cable to measure the insulation of each phase. If there is any short circuit in a phase, insulation value is 0 megaohm. Under the normal operating conditions, a motor inside the well should have megaohm insulation resistance. When the insulation resistance drops under 0.5 megaohm, there might be a insulation problem in winding. Test voltage should be at least 0 V DC. After extending power cables with a joint, same test procedures should be also appllied for insulation control while power cables are inside water. If insulation test result for any winding is lower than 00 megaohm, cable joint should be done again. Use Frequency Convertor and Soft Starter These points listed below should be taken into consideration while operating submersible motors with frequency convertor and soft starter. Needed precautions should have been taken to protect your frequency convertor from voltage flactuations. Flow rate around motor must be at least 0,5 m/s. If flow rate is not enough, flow inducer sleeve must be used to provide the needed flow rate. In systems which are operated by frequency convertor and soft starter, motor selection should be done as choosing next higher motor rate for pumps will provide long service life for motors. Motors should be operated between - Hz with frequency convertors. As the protective water layer can't be formed on thrust bearing at the lower frequencies, motor would get damaged. Dual slope frequency convertors should be used while using soft starter too. Voltage Drop and Cable Power Loss To determine the cable section it should be considered that the voltage drop must not exceed 3%. The formulas used for voltage drop calculation are given below. Direct starter ( cable) Direct starter ( cables in parallel) Star-delta starter L I q cos Pv Uv U : Cable length (m) : Current at nominal voltage (A) : Condutor section (mm) : Power factor : Power loss (%) : Voltage drop (%) : Nominal voltage (V) The power loss along the feeling cable has to be calculated adjacent to:
