Fault phenomenon: during the operation of the boiling water pump, the packing has a large water rejection, which causes the water inlet bearing in the bearing chamber to be damaged.

　　Cause analysis:

　　1) . the gland screw of packing is loose,

　　2) . the packing was not installed in place due to pressure deviation during installation, and the packing was not opened 90 ° during installation. The interface was in a straight line.

　　3) . the packing material is too hard to wear the shaft sleeve.

　　Treatment method:

　　1) . tighten the packing gland screws evenly, but do not tighten them too tightly, resulting in the packing and shaft locking heating.

　　2) When installing the packing, press the packing into the packing room symmetrically and evenly, and the interface must be staggered more than 90 °

　　3) . replace the packing with flexible and soft packing (oil soaked or high water base packing), and transform the packing if conditions permit

　　It is a rubber packing.

　　Effect after maintenance: use rubber injection packing, and the packing water shall be dropped at 10-20 drops per minute, so as to reduce the maintenance and repair workload of the pump body.

　　Precautions:

　　1) . the packing with good wear resistance and flexibility shall be selected.

　　2) . install the packing correctly.

　　Application of oil filtering trolley:

　　The portable filter oiler produced by our company is specially designed for the power plant, power station, industrial and mining enterprise's substation (room) lubricating oil depot, machine station, petroleum, chemical industry, metallurgy, national defense industry and other units. It is used to filter the impurities in transformer oil, turbine oil, lubricating oil, hydraulic oil, gasoline kerosene, antirust oil, cleaning oil, and other liquid oil, as well as pumping and filling oil, etc Working condition.

　　This machine is suitable for long distance and high lift oiling and pumping. It can effectively filter out all kinds of harmful impurities in the oil, ensure the safe operation of oil using equipment, reduce the wear of machinery during operation, improve the working efficiency of machinery, and guarantee the safe and efficient operation of the enterprise.

　　Features of oil filtering trolley:

　　1. The portable filter oiler is an oil delivery machine. At the same time of oil output, filter and remove all kinds of mechanical impurities in the oil, ensure the safety of mechanical operation, improve the working efficiency of machinery, and reduce environmental pollution.

　　2. High filtering precision, stainless steel filter element, can be cleaned and reused, saving user's use cost.

　　3. The trolley is portable and flexible, does not occupy space, and can be used for equipment overhaul and installation, field work, equipment repair, emergency, etc. it is a multi-purpose and good equipment, which is popular with users.
