KCB-135 in the normal operation of gear pump leakage causes and prevention of sudden
In the actual production run , sometimes we will find , KCB-135 gear oil pump has been running good, but suddenly they found a leak , but I do not know why ! , In fact, lead to a gear pump KCB-135 in normal operation , there are three sudden leak reasons, one mechanical seal leakage , the second is the installation appear different hearts, three are worn bushings . Pump casing and bushing into one ( collectively pump ) , seal is a mechanical seal . KCB gear pump is designed within a reasonable drain and return tank, gear to withstand the torque force at work a minimum , thus bearing loads of small, wear , high pump efficiency
KCB-135 gear oil leak suddenly functioning main reasons :
1 , evacuated, cavitation or longer hold pressure , resulting in seal damage ;
2 , the actual output of the pump is too small, the large number of medium circulation pump , heat build-up , causing the gasification medium , resulting in seal failure ;
3, the return flow is too large , resulting suction tube side of the container ( tower , tank , tank , tank ) bottom dregs , damaged seals ;
4 , for a long time outage , no manual re- start when the disk drive , adhesion and friction due to bad pull the sealing surface ;
5 , corrosive media , polymerizable , gumming substances increased ;
6, the dramatic changes in the ambient temperature ;
7 , frequent changes in operating conditions or adjustment ;
8 , such as a sudden power outage or downtime . KCB-135 gear oil pump suddenly leaks during normal operation , if not in time, will often lead to more accidents or loss shall be seriously and take effective measures.
Depending on the cause of the leaks we know how to solve , then I think the best thing is not to solve problems , but to avoid the problem, then
Preparing for KCB-135 gear pump start is very important.
KCB-135 gear oil pump before starting preparations:
1 , imported gear pump KCB-135 should be fitted with a filter , usually through the filter of the largest particles less than 0.1mm.
2 , check the unit and the connecting portion is fixed firmly ; connection check suction pipe sections and joints are sealed instrument .
3 , to check whether the coupling between the gap and a strict control of the two axes, the coupling should not exceed the outer runout 0.05mm, the coupling end surface runout should not exceed 0.1mm.
4 , the first starting working medium should be filled within the first gear pump KCB-135 .
5, the inlet check valve and the suction path of the discharge line of the exhaust valve is fully open .
6 Rotate the KCB-135 gear oil pump coupling, screw rotation should be uniform texture , light , without any reluctance or jammed rotating phenomenon . KCB-135 gear oil pump installation, commissioning and quality is good or bad , can directly affect the normal operation of the pump and affect the life and performance parameters of the pump. Vibration and noise of its units, also has a crucial impact. So pump installation , commissioning must be carried out carefully using appropriate tools .
In everyday use KCB-135 gear oil pump in the process, we should be in strict accordance with the operating instructions executed , is not only ready to start before the usual maintenance is also very important.
Many devices because of damage caused by improper operation . Correct method of operation is a key factor in the delay device lifetime .
