Description
Technical field
What the present invention relates to is mechanical seal detection experiment device.It can real simulation mechanical seal in actual applications, when routine running and accident condition, the operating mode of mechanical seal working chamber and the conversion of flow field environment and operating mode and flow field environment, detect, performance that test machines seal in all directions dynamically.For the development of mechanical seal, inspection and qualification.
Background technology
At present, the mechanical sealing performance proving installation of " GB/T14211-93 mechanical seal test method " is met as shown in Figure 1.Be made up of gearing, mechanical seal chamber analogue means, liquid storage tank device.
The wheel box b that gearing is driven by motor a is formed.
Liquid storage tank device by tank body 201, be opened in tank body 201 side feed tube 202, be opened in tank body bottom drain pipe 203, be opened in the liquid supplementation pipe 204 of tank body top side, be opened in the import/exhaust pipe 205 of tank body upper end, the cooling coil 206 itself and the inlet/outlet pipe 207,208 thereof that are arranged on bottom in tank body are formed.
The fluid reservoir of above-mentioned prior art mainly plays and stores and provide pressure medium effect, and can to a certain degree cool medium, elimination mechanical seal heat of friction is to the intensification of medium, in tank pressure medium and temperature adjustment and maintain controllability poor, also need to join special heating arrangement to coordinate as high-temperature medium will be provided, there is provided high-temperature medium to use so can not fully meet, can not meet and at any time regulating and controlling is converted to pressure medium, temperature, to meet the conversion request for utilization of working conditions change.
Mechanical seal chamber analogue means as shown in Figure 2, by cylindrical shell 101, axle sleeve 102, terminal pad 108, axially conveying pumping ring 104, cylindrical shell 101 front end shutoff mechanically-sealing apparatus 105 are formed, axle sleeve 102 is installed with the axial conveying axis that coordinates with cylindrical shell 101 inner ring surface to pumping ring 104, on cylindrical shell 101, the left and right sides of pumping ring 104 offers medium respectively and exports and input port 109,110.When it uses, cylindrical shell 101 is fixedly connected with and is arranged on the wheel box b of gearing, and axle sleeve 102 coordinates with the output shaft of wheel box b to be installed and is bolted to connection.Terminal pad 108 is fixedly connected with the front end of cylindrical shell 101, on terminal pad 108 and axle sleeve 102, then install the tested mechanically-sealing apparatus 107 be made up of gland 171, static components 172, moving ring assembly 173.
