Title: Controlling method for operation of compressor
Inventor: WAKABAYASHI SHINICHI
IPC: F25B49/02
Filed: 1990-11-30
Abstract: PURPOSE:To prevent a compressor from seizing by incorporating an electrostatic capacity type sensor into the lower part of the compressor to effect the feedback control of the diluting degree signal of oil detected by the sensor. CONSTITUTION:An electrode 1 out of a sensor and an electrode inside of the sensor, which are insulated surely by Teflon 11, are attached to a sensor body 3. After attaching lead wires 7 to both electrodes, the lead wires 7 are inserted into a sensor guide 4 welded to the lower part of a compressor 10, then, the sensor guide 4 is fixed to a sensor body 3 through bolts 8. According to this method, the electrode I in the sensor and the other electrode 2 in the sensor are dipped into the lubricating oil of the compressor 10. When the compressor 10 is operated, liquid refrigerant is solved into the oil by the operating condition of the compressor whereby an electrostatic capacity outputted through the lead wires 7 is changed depending on the difference of conductivities of the oil and the liquid refrigerant. The electrostatic capacity is detected and when the value satisfies a preset deciding value, the operation of the compressor 10 is continued as it is and when the detecting value has not achieved the preset value, the operation enters protecting control. According to this method, the seizing of the compressor 10, which is generated due to the diluting condition of the oil, can be prevented.

Abstract: PURPOSE:To reduce the occurrence of cuts, cracks and the like due to gas generation, by granulating a ceramic material powder body, adding an organic binder thereto, regulating a mud slurry and casting it in a mold, calcining it tentatively at a specified temperature as occasion demands after the molding is dried, and then calcining the molding obtained in an isostatic press. CONSTITUTION:Globular granulates of 10-1000mum in grain size are obtained, for example from a ceramic material powder body by a spray dry and granulating method. A mud slurry is conditioned by adding an organic binder thereto and casted into a mold made of resin and others. The obtained molding is dried and tentatively calcined at 600-800 deg.C as occasion demands. Next, the molding is coated with latex, etc., and dried to cover its whole surface and pressed isostatically at pressures of hundreds to thousands kg/cm<2>. By calcining the pressed molding with a normal method, the vaporization of water from the molding becomes easy because the space between particles is relatively large due to granulates used in molding.
