                                                                    Installation Instructions
1, the installation of pipe weight should not bear on the pump, or vulnerable ring pump;
2, the pump is the overall structure of the motor, the factory has been factory calibration, so no need to adjust the installation, so the installation is very convenient;
3, before installing the pump should carefully check whether there is any impact on the pump runner pump running hard materials, (such as stones, iron sand, etc.) in case of pump running back loss of flow components;
4, into the installation must be tightened anchor bolts, and each interval in fact, should check the pump during the passage to prevent its loosening, so as to avoid the pump start violent vibration and affect the performance;
5, In order to maintain the convenience and safety, install a regulating valve on the pump inlet and outlet piping and install a pressure gauge near the pump inlet and outlet. For high lift, in order to prevent water hammer, it should also be installed in front of the outlet gate Check valve only to cope with sudden power outages and other lost power accidents, so as to ensure that the pump running in the best conditions, increasing the life of the pump;
6, the pump for a suction occasion, should be equipped with the end of the valve, and the inlet pipe should not have too many corners at the same time there may be leakage, leakage phenomenon, so as not to affect the pump suction performance;
                                                                   Start and stop
Preparation before starting
1, pull the coupling by hand, the impeller should be no card grinding phenomenon, flexible rotation;
2, open the inlet valve, open the exhaust valve so that the liquid filled the entire pump chamber, and then close the exhaust nozzle;
3, such as the delivery of hot liquid, before starting should be preheated, heating rate of 50 ºC / h, the pump is preheated by the continuous circulation of liquid delivery to achieve, so that all parts of the heated uniform;
4, should be manually activated KCB horizontal Multistage gear oil Centrifugal Pump several times so that the lubrication water into the mechanical seal face;
5, move the motor, the steering is correct.
Start and run
1, fully open the inlet valve, close the discharge pipe door;
2, connect the power, when the pump reaches the normal speed, gradually open the valve on the discharge pipe and adjust to the required conditions;
3, observe the instrument readings, check the shaft seal leakage, the normal timing of mechanical seal leakage 3 leakage / min, check the motor, the bearing temperature ≤ 70 ºC, if abnormal, should be promptly addressed.
parking
1, gradually close the discharge pipe valve;
2, close the inlet valve
3, such as the ambient temperature is below 0 ºC. Should drain the pump liquid, so as not to freeze crack pump;
4, such as long-term disabled, the pump should be disassembled clean, packaging and custody.
                                                                Repair and maintenance
In operation, maintenance and care
1, the inlet pipe must be highly sealed, can not leak, leak;
2, KCB horizontal Multistage gear oil Centrifugal Pump are prohibited from long-term operation under cavitation;
3, prohibit the KCB horizontal Multistage gear oil Centrifugal Pump operating in high flow conditions, the motor over-current long-term operation;
4, Regularly check the motor current in the pump operation, try to make the pump run in the design conditions;
5, KCB horizontal Multistage gear oil Centrifugal Pump in operation should be someone care, so as to avoid accidents;
6, KCB horizontal Multistage gear oil Centrifugal Pump for each 500 hours of operation to refuel;
7, KCB horizontal Multistage gear oil Centrifugal Pump after long-term operation, due to mechanical wear and tear, so that the unit noise and vibration increase, parking inspection, the need to change into the vulnerable parts and bearings, unit overhaul period is generally one year.
Mechanical seal maintenance and repair
1, mechanical seal lubricating fluid should be clean without solid particles;
2, mechanical seal is strictly prohibited in the case of dry grinding;
3, KCB horizontal Multistage gear oil Centrifugal Pump (motor) should be activated a few times before starting, so as not to cause a sudden start-up mechanical seal rupture damage.
                                                     Causes of failure and troubleshooting                         

Trouble phenomenon	May cause the reason	To exclude
1,The pump does not water	Inlet valve is not open, out of the pipeline obstruction, Impeller flow blockage Motor running in the wrong direction, motor phase loss is very slow speed Suction tube leaks Pump is not filled with liquid, the pump cavity with air Inadequate supply of imported water, suction stroke is too high, leakage valve at the end Pipeline resistance is too large, inappropriate pump selection	Check, remove obstruction Adjust the motor steering, tighten the motor wiring Tighten the sealing surface, remove the air Open the pump cover or open the exhaust valve and drain the air Stop checking, adjusting Reduce the pipe bend, re-select the pump
2, The first pump to check the flow of less than	Pipe, pump runner or impeller blockage, scale deposition ... Low voltage Impeller wear	First exclude 1 Remove the obstruction and readjust the valve opening Regulated Replace the impeller
3,The power is too large	Than the rated flow Suction stroke is too high Pump bearing wear	Tear to adjust the flow, off the small outlet valve Lower Replace the bearing
4, Noise vibration	Tube support instability Liquid mixed with gas Cavitation produces Bearing damaged Motor overloaded to run	A solid pipe Raise suction pressure and exhaust Reduce the degree of vacuum Replace the bearing Adjust by 5
5, The motor heat	Flow is too large, overload operation Partial friction Motor bearing damaged Low voltage	Off the small outlet valve Check exclusion Replace the bearing Regulated
6,Pump leakage	Mechanical seal wear The pump has sand holes or cracks The sealing surface is not smooth Loose mounting	Screws Welding repair or replacement Trimming Tighten
