Abstract
The utility model discloses a protective device for a lubricant pump. The protective device comprises a motor, a lubricant pump, an outlet pipe, a lead and a shutdown device, wherein the outlet pipe of the lubricant pump is provided with a connecting pipe and connected with a compression gauge with electric contacts through a valve, and the lead connects the compression gauge with electric contacts and the shutdown device. Since the outlet pipe of the lubricant pump is provided with a connecting pipe and connected with a compression gauge with electric contacts through a valve, and the lead connects the compression gauge with electric contacts and the shutdown device, an interlocking shutdown pressure value of the compression gauge with electric contacts is set. When the pressure of the lubricant in the pipe reaches the set value, an alarm normally opened contact of the compression gauge with electric contacts is closed, and signals are sent to the shutdown device through the lead. The motor stops working, and the lubricant pressure falls, thereby preventing occurrence of safety accidents.
Description
Technical field
The utility model relates to OIL IN LUBRICATING OIL PRODUCTION system field, is specifically related to a kind of lubricating pump protective gear.
Background technique
In recent years, quickening along with the mechanization process, machinery increases year by year with the use amount of lubricant oil, when OIL IN LUBRICATING OIL PRODUCTION, lubricating pump is a kind ofly under the drive of motor crude lube stock to be raised to certain pressure, and crude lube stock is supplied with the common equipment of manufacturing mechanism by oil circuit, but when lubricating pump is worked, if the equipment that oil circuit stops up or drives goes wrong, the pressure of oil pipe will raise under the effect of lubricating pump gradually in the oil circuit, and in the case, oil pipe is booster probably, because the lubrication pressure in the pipeline is high pressure oil, if booster then can cause serious personal injury to the staff around it, simultaneously, lubricant oil leaks in a large number, not only befouling environment but also can cause the certain economic loss.
The model utility content
For solving the problems of the technologies described above, we have proposed a kind of reasonable in design, simple in structure and safe and reliable lubricating pump protective gear.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of lubricating pump protective gear is by motor, lubricating pump, oil outlet tube, lead and arresting gear; The oil outlet tube of described lubricating pump is provided with PRESSURE PIPE, and is connected with a pressure gauge with electric contact by a valve, and described lead is electrically connected described pressure gauge with electric contact with described arresting gear.
Preferably, described arresting gear is provided with warning device.
Pass through technique scheme; the utility model is provided with PRESSURE PIPE by the oil outlet tube of described lubricating pump; and be connected with a pressure gauge with electric contact by a valve; described lead is electrically connected described pressure gauge with electric contact with described arresting gear; the interlocking of the pressure gauge with electric contact that configures is shut down force value; when the pressure of the lubricant oil in pipeline reaches setting value; the warning normally opened contact closure of pressure gauge with electric contact; give arresting gear by lead with the signal tradition; motor quits work; lubricating oil pressure falls after rise, thereby has avoided the generation of security incident.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the disclosed a kind of lubricating pump protective gear of the utility model embodiment.
Numeral and the represented corresponding part title of letter among the figure:
1. motor 2. lubricating pumps 3. oil outlet tubes 4. leads
5. arresting gear 51. warning devices 6. PRESSURE PIPE 7. valves
8. pressure gauge with electric contact
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Below in conjunction with embodiment and embodiment the utility model is described in further detail.
Embodiment.
As shown in Figure 1, a kind of lubricating pump protective gear is by motor 1, lubricating pump 2, oil outlet tube 3, lead 4 and arresting gear 5; The oil outlet tube 3 of described lubricating pump 2 is provided with PRESSURE PIPE 6, and is connected with a pressure gauge with electric contact 8 by a valve 7, and described lead 4 is electrically connected described pressure gauge with electric contact 8 with described arresting gear 5.
Wherein, described arresting gear 5 is provided with warning device 51.
The lubricating pump protective gear workflow of the technical program is as follows: as shown in Figure 1; the crude lube stock of lubricating pump 2 outputs enters production system by oil outlet tube 3; the force value of normal operating pressure for allowing; because the outlet of the oil outlet tube 3 of lubricating pump 2 arranges a pressure gauge with electric contact 8(its alarm pressure value is set; the force value that alarm pressure value allows greater than normal operating pressure); draw two leads 4 from normal battle of the warning of pressure gauge with electric contact 8; and connection motor arresting gear 5; when stopping up appears in the pipeline of carrying crude lube stock; when lubricating oil pressure is elevated to alarm pressure value; the warning normally opened contact closure of pressure gauge with electric contact 8; by lead 4 signal is passed to arresting gear 5, motor 1 quits work.Therefore, adopt the technical program, in lubricating pump 2 outlets overpressure protector is set, in case when superpressure occurring, occur interlocking immediately and shut down, warning device 51 sends acoustooptic alarm simultaneously, reminds operator to take measures, thereby has avoided the generation of security incident.
Pass through technique scheme; the utility model is provided with PRESSURE PIPE 6 by the oil outlet tube 3 of described lubricating pump 2; and be connected with a pressure gauge with electric contact 8 by a valve 7; described lead 4 is electrically connected described pressure gauge with electric contact with described arresting gear; the interlocking of the pressure gauge with electric contact that configures is shut down force value; when the pressure of the lubricant oil in pipeline reaches setting value; the warning normally opened contact closure of pressure gauge with electric contact; give arresting gear by lead with the signal tradition; motor quits work; lubricating oil pressure falls after rise, thereby has avoided the generation of security incident.
Above-described only is a kind of lubricating pump protective gear preferred implementation of the present utility model; should be understood that; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
