Description
Technical field
The present invention relates to plant maintenance technical fields, and in particular to a kind of bush temperature detecting thermal resistance installation method.
Background technique
Bearing shell (including main thrust watt, secondary thrust bearing shoe valve, branch in large-scale compressor group in domestic and international oil-refining chemical enterprise
Support watt etc.) temperature be unit safety operation important monitoring parameters, for these parameters of correct measurement, it is necessary to assure each thermometric
Probe-thermal resistance and conducting wire install and design the correct cooperation with installation technical ability inside unit.Large-sized unit manufacturer is to each at present
More unreasonable place and difficulty of construction are deposited from the embedded thermal resistance installation Position Design of large-sized unit and assembling, to go out
Existing setup error and installation quality problem, cause Thermistor Temperature Measurement component and harness damage, until large-sized unit is made to lose bush temperature detecting
Point failure, threatens to unit operational safety.
After aromatisation device C3202 high pressure cylinder end compressor is uncapped, following problem is found:
(1) thermal resistance and conducting wire install detail mistake, and thermal resistance conducting wire is between thrust bearing shoe valve and rotor propulsion disc in clearance groove
It leads to outside unit shell, conducting wire and thrust disc, also without fixing means, make thermal resistance conducting wire directly and high speed rotation without quarantine measures
Rotor propulsion disc friction, be directed at two open traverse of thrust bearing shoe valve top and rub.
(2) thermal resistance conducting wire is drawn from thrust bearing shoe valve and is routed in complex gap without any fixation in unit, is directed at heat
Resistance wire is loose in clearance groove between bearing shell and rotor propulsion disc, is easily close to high-speed rotating thrust disc, accelerates conducting wire and is ground
Disconnected speed.
(3) two Zhizheng benefit exit of thrust bearing shoe valve lower part, leader cable are just drawn from lower Oil Guide cover board side, so
It does not damage.
After aromatisation device C3202 low pressure (LP) cylinder end compressor is uncapped, the problem of discovery, has:
(1) thermal resistance and conducting wire install detail mistake, and thermal resistance conducting wire is between thrust bearing shoe valve and rotor propulsion disc in clearance groove
It leads to outside unit shell, conducting wire and thrust disc, also without fixing means, make thermal resistance conducting wire directly and high speed rotation without quarantine measures
Rotor propulsion disc friction, be directed at four thermal resistance conducting wires of thrust bearing shoe valve and rub.
(2) four thermal resistance conducting wires of thrust bearing shoe valve are drawn out of all rotor propulsion disc top and Oil Guide cover board, can not be determined
Position is fixed, must be rubbed by high-speed rotating rotor propulsion disc.
(3) wiring is directed at thermal resistance conducting wire without any fixation to thrust bearing shoe valve thermal resistance conducting wire in complex gap in machine
It is loose in cover board clearance groove, it is easily close to high-speed rotating thrust disc, accelerates the speed that conducting wire is rubbed.
After aromatisation device C3201 compressor is uncapped, following problem is found:
(1) thrust bearing shoe valve thermal resistance conducting wire moves towards detail mistake, its conducting wire of thermal resistance is empty between thrust bearing shoe valve and rotor propulsion disc
It is led to outside unit in slot, and thermal resistance conducting wire and thrust disc, also without fixing means, keep thermal resistance conducting wire straight without quarantine measures
It connects and rubs with high-speed rotating rotor propulsion disc, be directed at two lead-out wires and rub.
(2) thermal resistance conducting wire is drawn in unit from thrust bearing shoe valve without any fixation, is directed at thermal resistance conducting wire in thrust bearing shoe valve
It is loose in clearance groove between rotor propulsion disc, accelerate conducting wire to rub.
(3) the master/slave two thermal resistance conducting wires of thrust bearing shoe valve in right side are just drawn from exit, leader cable just on from leading
Oil cap plate side is drawn, so not damaging.
Master/slave thrust bearing shoe valve thermal resistance leader cable does not have dedicated cabling channel, and conducting wire placement can not avoid high-speed rotation portion
Part, be directed at thermal resistance conducting wire encounter rotor part and wear and rupture damage institute extremely；Its is secondary the reason is that thermal resistance cable does not close
The positioning and fixation of reason, cause thermal resistance cable in limited gap, due to the vibration of unit, the impact of lubricating oil, Yi Jiang
Loose cable is pushed high-speed rotating rotor to and is worn.
