Description

Cam-type lubricating oil heating device

Technical Field

The invention relates to the technical field of rapid heating of lubricating oil, in particular to a cam type lubricating oil heating device.

Background

At present, the compressor compresses air or nitrogen into a high pressure state, and there are two main ways of pressurizing natural gas by the compressor, one is a centrifugal compressor, and the other is a reciprocating compressor. In winter, the lubricating oil in the compressor oil tank has high viscosity and poor fluidity, and a circulating electric heating device is needed to heat the lubricating oil, but the electric heating device and the lubricating oil are always in a static state, the lubricating oil in contact with the electric heating device is heated to 40 ℃ firstly, the lubricating oil at the edge part and the bottom part of the compressor oil tank needs a long time to be heated, and the defect of long time needed for warming up exists. Because the lubricating oil does not reach the required starting temperature of the compressor, the starting time of the compressor is seriously delayed, if the internal mechanical part of the compressor operates at the temperature of 40 ℃ lower than the lubricating oil, the cold state abrasion of the mechanical part is accelerated, the service life of the compressor is shortened, and the service cycle of the lubricating oil is shortened.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide a cam type lubricating oil heating device which has the advantages of compact structure, shortened lubricating oil heating, quick reduction of lubricating oil viscosity, simple operation and prolonged service life of a compressor.

The purpose of the invention is realized by the following technical scheme: the utility model provides a cam-type lubricating oil heating device, it includes the box, sets up in the case lid at box top and sets up in the cam of case lid top, the top of case lid be provided with the guiding hole, be provided with the loose axle in the guiding hole, set up the recess that is located the box on the cylinder of loose axle, the bottom surface and the loose axle of recess are the contained angle setting, the lower tip of loose axle is provided with presses the oil board, the lateral wall of box on be provided with the oil drain pipe, the box just is located its basal surface and has set firmly the spring, the top of spring links firmly on the loose axle, just it all still is provided with many heating pipes to be located.

The box cover is characterized by further comprising a rack arranged above the box cover, and the cam is rotatably arranged on the rack through a rotating shaft.

The bottom of the box body is provided with a sleeve, and the spring is arranged in the sleeve.

The heating device also comprises a controller, wherein the controller is connected with the heating pipe.

The movable shaft is vertically arranged.

The invention has the following advantages: the invention shortens the heating of the lubricating oil, quickly reduces the viscosity of the lubricating oil, has simple operation and prolongs the service life of the compressor.

Detailed Description

The invention will be further described with reference to the accompanying drawings, without limiting the scope of the invention to the following:

as shown in fig. 1-3, a cam-type lubricating oil heating device, it includes box 1, set up in case lid 2 at box 1 top and set up in the cam 3 of case lid 2 top, the top of case lid 2 be provided with guiding hole 4, be provided with loose axle 5 in the guiding hole 4, the vertical setting of loose axle 5 has seted up the recess 6 that is located box 1 on the cylinder of loose axle 5, the bottom surface of recess 6 is the contained angle setting with loose axle 5, when loose axle 5 upwards moved, recess 6 can bring the lubrication in the box 1 into wherein.

Lower tip of loose axle 5 be provided with and press oil board 7, box 1 in the splendid attire be equipped with the lubricating oil that is used for lubricated compressor, be provided with oil extraction pipe 8 on the lateral wall of box 1, the spring 9 has set firmly on the box 1 is just located its basal surface, the top of spring 9 links firmly on loose axle 5, just be located spring 9 both sides in box 1 and all still be provided with many heating pipes 10, it still includes the controller, controller and heating pipe 10 be connected, the start-up or the closing of operating personnel accessible controller control heating pipe 10 realize remote heating lubricating oil.

The box cover structure further comprises a frame 11 arranged above the box cover 2, and the cam 3 is rotatably arranged on the frame 11 through a rotating shaft. The bottom of the box body 1 is provided with a sleeve 12, and the spring 9 is arranged in the sleeve 12.

The working process of the invention is as follows: in an initial state, the cam 3 is pressed on the top of the movable shaft 5, the spring 9 is in a compressed state, the oil pressing plate 7 presses the lubricating oil to the left and right sides, the lubricating oil is in contact with the heating pipe 10, the heating pipe 10 heats the lubricating oil, the fluidity heating of the lubricating oil is realized, the contact area between the heating pipe and the lubricating oil is increased, and the viscosity of the lubricating oil is rapidly reduced; after the cam 3 rotates clockwise for a half turn, the movable shaft 5 moves upwards under the action of the restoring force of the spring 9, and meanwhile, the groove 6 carries part of lubricating oil to move upwards along with the movable shaft 5; after the cam 3 rotates for a half turn again, the cam 3 presses the movable shaft 5 to generate inertia force, lubricating oil overflows from the inertia force lower groove 6 and enters the lubricating oil liquid level, the liquid level is disturbed after the lubricating oil drips, the contact area between the heating pipe and the lubricating oil is further increased, the lubricating oil is rapidly heated to 40 ℃ in a short time, the starting time of the compressor is shortened, and the utilization rate of the compressor is improved.
