The mechanical seal detector can timely find out the leakage reason of corrugated pipe mechanical seal,so as to reduce the medium loss caused by the leakage of the dynamic device, and protect the environment.
Description
Technical field
[0001] the utility model relates to a kind of detector in the petrochemical industry, particularly a kind of machine envelope detector.
Background technology
Mechanical seal is crucial consumable accessory on the power-equipment of petroleum chemical enterprise, especially on pump.When medium was gas or the liquid of inflammable and explosive easy pollution, more need guarantee it can not reveal.More advanced sylphon seal is adopted in the mechanical seal of installing on the existing pump mostly, and sylphon seal produces the main cause of revealing and is: 1, dynamic and static ring friction pair wearing and tearing; 2, dynamic and static ring friction pair is owing to not producing dynamic and static ring end face injustice at that time and cause leakage dispatching from the factory or install; 3, the excessive corrugated tube of pressure is impaired.Owing to the leakage that different reasons produce need be adopted different solutions.If therefore can not in time find the leakage reason, will strengthen the dielectric loss that moves equipment leakage and bring and cause environmental pollution, increase workpeople's labour intensity simultaneously.
Summary of the invention
Thereby the utility model technical matters to be solved is to overcome can not in time finding of existing in the background technology to reveal reason and strengthen the dielectric loss that moving equipment leakage brings and cause environmental pollution problems; And provide a kind of machine to seal detector; This machine envelope detector can in time be found corrugated tube machine envelope and produce leakage reasons; Reduce the dielectric loss that moving equipment leakage causes, the protection environment.
The utility model solves its problem and can reach through following technical scheme: this machine envelope detector comprises fuel reserve tank and line oiler monomer; Fuel reserve tank top connects the line oiler monomer; The main shaft of described fuel reserve tank is equipped with handle outward; Described line oiler monomer connects oil pipe through pipeline, and described oil pipe junctor seals up the gland seat and the machine envelope presses down cage, and machine is sealed up gland seat and machine envelope and pressed down between cage from top to bottom junctor envelope rotating ring, machine envelope stationary ring and machine envelope corrugated tube successively; Described machine is sealed up gland seat, machine envelope rotating ring, machine envelope stationary ring, machine envelope corrugated tube and machine envelope and is pressed down the cage center and be equipped with pull bar; Machine is sealed up on the pull bar on gland seat top the adjustment nut is housed, and has oil hole between the machine envelope rotating ring of pull bar and machine envelope stationary ring, and pull bar lower end and machine seal and press down the cage center pit and be threaded.
The utility model and above-mentioned background compared with techniques can have following beneficial effect: this machine envelope detector is owing to adopt said structure, and the contact compression degree of simulation dynamic and static ring when pump turns round in time conveniently found corrugated tube machine envelope and produced leakage reasons.Reduce corrugated tube machine envelope and accessory cost of use, alleviated the dielectric loss that brings by moving equipment leakage and caused environmental pollution, reduced workpeople's labour intensity.Energy-saving and cost-reducing, time saving and energy saving.
Description of drawings:
Accompanying drawing 1 is the connection schematic flow sheet of the utility model;
Accompanying drawing 2 is that the utility model pull bar junctor is sealed up the structural representation that presses down cage.
Among the figure: 1-handle, 2-fuel reserve tank, 3-tensimeter, 4-line oiler monomer, 5-operation valve; The 6-machine is sealed up the gland seat, and 7-machine envelope presses down cage, 8-pull bar, 9-machine envelope rotating ring, 10-machine envelope stationary ring; 11-machine envelope corrugated tube, the 12-oil pipe, 13-adjusts nut, 14-oil hole, 15-outside framework oil seal.
Embodiment:
To be described further the utility model below in conjunction with accompanying drawing:
Shown in Figure 2 like accompanying drawing 1 combination, this machine envelope detector comprises fuel reserve tank 2 and line oiler monomer 4, and fuel reserve tank 2 tops connect line oiler monomer 4; The main shaft of described fuel reserve tank 2 is equipped with handle 1 outward; Described line oiler monomer 4 connects oil pipe 12 through pipeline, described oil pipe 12 cylinder lever connecting rods 8, and adjustment nut 13 is equipped with in pull bar 8 upper ends; Upper end, pull bar 8 axle center has the hole; Terminal corresponding pull bar 8 bodies in hole radially have the oil hole 14 of UNICOM, and junctor is sealed up gland seat 6 and machine envelope and pressed down cage 7 on the pull bar 8, and machine is sealed up gland seat 6 and machine envelope and pressed down 7 of cages from top to bottom junctor envelope rotating ring 9, machine envelope stationary ring 10 successively; Machine is sealed up outside framework oil seal 15 is installed on the gland seat 6; Pull bar 8 tops adjustment nut 13 machines of being sleeved on are sealed up on the outside framework oil seal 15 of gland seat 6,10 of pull bar 8 oil holes, 14 corresponding machine envelope rotating rings 9 and machine envelope stationary rings, and pull bar 8 lower ends press down cage 7 center pits with the machine envelope and are threaded; Be connected to tensimeter 3 and operation valve 5 on the described oil pipe 12.
When this machine envelope detector uses, with after injecting media such as water or machine oil in the fuel reserve tank, be installed to machine envelope dynamic and static ring on the upper and lower gland seat of pressing machine earlier, fix through the hole on the gland respectively.Machine is sealed up gland and is enclosed within on the pull bar, and machine envelope lower cover is connected with pull rod screw, machine seal decrement through the adjustment nut on the pull bar to machine seal up, the lower cover relative position adjusts, make machine seal decrement and reach the standard use value.With crank handle liquid in the fuel reserve tank is passed through line oiler monomer and oil pipe again, inject in the machine sealing chamber through oil hole on the pull bar and pressurize, pressure shows through tensimeter, to reach the force value of regulation.If at this moment liquid is driven, the stationary ring end face is revealed, prove that the dynamic and static ring friction pair has problem, this phenomenon can be handled through the dynamic and static ring end surface grinding.If liquid is revealed from corrugated tube, prove the corrugated tube leakage, can be through changing the corrugated tube solve problem.
