Abstract
The utility model discloses a lubricating oil starvation alarm device for a horizontal scraper centrifuge, which comprises an alarm device mounted on a lubricating oil inlet pipeline of a horizontal scraper centrifuge bearing. Lubricating oil enters the centrifuge bearing from an oil inlet and flows out of the centrifuge bearing from an oil outlet, and when a flowmeter detects that lubricating oil flow is lower than a set value, the alarm device acts to give out alarm signals, so that damage of the centrifuge bearing caused by poor lubrication is avoided. When the centrifuge is provided with the lubricating oil starvation alarm device, repair and replacement times of the bearing are decreased, the service cost of the centrifuge is reduced, and simultaneously the service life of the centrifuge is prolonged.
Description
Technical field
The utility model relates to centrifuge machinery field, specifically is the lubricated oil starvation warning device of a kind of horizontal type scraper centrifuger.
Background technology
Centrifuge is to utilize centrifugal force, the machinery of each component in separating liquid and solid particle or liquid and the mixtures of liquids.Centrifuge has a cylinder that rotates at a high speed around axis own, is called rotary drum, usually by Motor Drive.After separation of material adds rotary drum, rotated with speed by rapid the drive with rotary drum, each component is separated under centrifugal action, and discharges respectively.Usually, the rotary drum rotating speed is high more, and separating effect is also good more.Centrifuge is widely used in departments such as chemical industry, oil, food, pharmacy, ore dressing, coal, water treatment and boats and ships.
Scraper centrifugal machine mainly is made up of support, workspace location and power-section unit, the junction in workspace location and power-section unit, and main shaft drives the rotary drum running and realizes centrifugal action.During the centrifuge scraper, wing is slowly cut the rotary drum bed of material when rotary drum rotates, with material progressively scraping come off.Horizontal type scraper centrifuger is the perforated wall centrifuge of continuous running, intermittently operated, and its control mode is control automatically, also can manually control.Processes such as the charging in the centrifuge operating process, separation, washing, dehydration, discharging and filter cloth regeneration are generally all finished under full-speed state, and the single cycle time is short, and treating capacity is big, and can obtain dried filter residue and good clean result.
Employed flow of lubrication often hinders for some reason and does not reach setting value during horizontal type scraper centrifuger running now commonly used, causes the centrifuge bearing to damage because of insufficient lubrication.
The utility model content
At the problem that prior art exists, the purpose of this utility model is to provide a kind of lubricated oil starvation warning device of horizontal type scraper centrifuger that lubricated oil starvation warning device is installed.
The utility model takes following technical scheme to realize:
A kind of horizontal type scraper centrifuger lubricates the oil starvation warning device, comprises warning device, and described warning device is installed on the lube oil inlet pipe road of horizontal type scraper centrifuger bearing.
Described warning device comprises oil-in, oil-out, container and signal relay, described oil-in is arranged on the bottom of container, oil-out is arranged on the top of container, be provided with flowmeter in the described container and near switch, described flowmeter be connected near switch, connect the outer signal relay of container near switch.Lubricating oil advances from oil-in, and oil-out goes out, when the detected flow of lubrication of flowmeter less than when setting value, alarm signal is sent in the warning device action.
Described flowmeter can be differential pressure flowmeter, float-type flowmeter or blocked flake type flowmeter.
Described warning device adopts glass or transparent plastic to make, and perhaps has windowpane on the warning device wall, with the convenient liquid level of lubricating oil and the duty of each element of observing.
The beneficial effects of the utility model are:
A kind of horizontal type scraper centrifuger of the utility model lubricates the oil starvation warning device, on the lube oil inlet pipe road of horizontal type scraper centrifuger bearing, warning device is installed, lubricating oil advances from oil-in, oil-out goes out, when the detected flow of lubrication of flowmeter less than when setting value, alarm signal is sent in warning device action, avoids centrifuge bearing lubrication bad and damage.The centrifuge of the utility model warning device is installed, has reduced the maintenance of bearing and changed number of times, reduced the use cost of centrifuge, prolonged the service life of centrifuge simultaneously.
Description of drawings
Fig. 1 is the structural representation of the lubricated oil starvation warning device of the utility model horizontal type scraper centrifuger;
Among the figure: 1-oil-in, 2-oil-out, 3-container, 4-windowpane, 5-flowmeter, 6-be near switch, the 7-signal relay.
The specific embodiment
Below by specific embodiment the utility model is described in further detail.
Shown in Figure 1 as Figure of description, a kind of horizontal type scraper centrifuger lubricates the oil starvation warning device, comprises warning device, and warning device is installed on the lube oil inlet pipe road of horizontal type scraper centrifuger bearing.Warning device comprises oil-in 1, oil-out 2, container 3 and signal relay 7, and oil-in 1 is arranged on the bottom of container 3, and oil-out 2 is arranged on the top of container 3.Be provided with flowmeter 5 in the container 3 and near switch 6, flowmeter 5 with link to each other near switch 6, connect the outer signal relay 7 of containers near switch 6.Have windowpane 4 on the warning device wall, with the convenient liquid level of lubricating oil and the duty of each element of observing.Lubricating oil advances from oil-in 1, and oil-out 2 goes out, when flowmeter 5 detected flow of lubrication less than when setting value, will be by sending alarm signal with the signal relay 7 that is connected near switch 6, avoid centrifuge bearing lubrication bad and damage.The centrifuge of the utility model warning device is installed, has reduced the maintenance of bearing and changed number of times, reduced the use cost of centrifuge, prolonged the service life of centrifuge simultaneously.
