Abstract
The utility model discloses a ware over -temperature alarm device is closed to breaker hydraulic lotus root, including install on the pump impeller shell pressure -sensitive device and with pressure -sensitive device corresponds the travel switch who sets up on motor base, last being equipped with of pressure -sensitive device is stretched out and is triggered when the oil temperature is too high travel switch's tentacle. The utility model discloses a ware over -temperature alarm device is closed to breaker hydraulic lotus root, set up travel switch through setting up pressure -sensitive device and correspond with pressure -sensitive device on the pump impeller shell, when the oil temperature exceedes the scope of setting for, pressure -sensitive device's tentacle stretches out and cooperates with the travel switch contact, and trigger travel switch, then report to the police with the electric alarm of being connected of travel switch, remind maintainer to seek the problem reason by the hard stop, avoid huge economic losses's emergence, and has an accuracy, and the device is safe, reliabl, simple structure with install advantage with low costs additional.
Description
Technical field
This utility model relates to a kind of detection alarm device, concrete for a kind of disintegrating machine fluid power coupling apparatus excess temperature alarm device.
Background technology
Disintegrating machine is the important component part in ingot-casting milling machine milling process, because some reasons can cause disintegrating machine fluid coupling high oil temperature, such as: design of Hydraulic System is unreasonable, it is improper that oil product selects, and in hydraulic oil container, oil level is too low, is mixed into air in hydraulic system, oil filter blocks, parts wear is serious, and the ambient temperature that motor winding, bearing cause is the most high, and these all can cause a series of serious consequence.
1, high oil temperature, makes oil viscosity decline, and leakage rate increases, and reduces volumetric efficiency.Owing to the oil film at the mobile positions such as oil viscosity reduces, guiding valve is thinning and is cut through, frictional resistance increases, and causes abrasion aggravation, system heat generation, and temperature raises.
2, high oil temperature, after making fluid high-temperature oxydation, produces the impurity such as colloid and Colophonium, the aperture in clogging hydraulic element and gap.Causing pressure valve pressure regulation malfunctioning, commutation stubbornly refused by flow valve instability of flow and direction valve card, and metal tubes elongation bent, and all multiple faults such as even ruptures.
3, high oil temperature, causes thermal deformation, makes the gap between the different relative motion part of thermal coefficient of expansion diminish, the most stuck, is allowed to the ability of losing the job.
4, high oil temperature, can make rubber seal produce soften, expand and harden, the deformation such as be full of cracks, reduce its service life, loss of seal performance, cause leakage, leakage can generate heat further again promotion temperature rising.
5, oil temperature raises, and the air separation pressure drop of oil is low, and in oil, dissolved air overflows, and produces air pocket, causes hydraulic work system performance to reduce.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of disintegrating machine fluid power coupling apparatus excess temperature alarm device, can not only send alarm signal when bonder high oil temperature, and have simple in construction and the advantage installing low cost additional.
For reaching above-mentioned purpose, this utility model following technical scheme of offer:
A kind of disintegrating machine fluid power coupling apparatus excess temperature alarm device, including the pressure sensitive device being arranged on pump impeller shell and the travel switch being correspondingly arranged on motor base with described pressure sensitive device, described pressure sensitive device is provided with when high oil temperature the tentacle stretching out and triggering described travel switch.
Further, also include that control system, described control system include that controller and alarm, described controller electrically connect with described travel switch.
Further, described control system also includes the temperature sensor for detecting oil temperature and for controlling the control circuit that described tentacle is flexible, and described controller electrically connects with described temperature sensor and control circuit respectively.
The beneficial effects of the utility model are:
Disintegrating machine fluid power coupling apparatus excess temperature alarm device of the present utility model; by arranging pressure sensitive device on pump impeller shell and being correspondingly arranged travel switch with pressure sensitive device; when oil temperature exceedes the scope of setting; the tentacle of pressure sensitive device stretches out and contacts cooperation with travel switch; and trigger travel switch; the alarm equipment alarm then electrically connected with travel switch; remind attendant can search problem reason with hard stop; the generation of Redeem large economic loss, and there is accurate, safe and reliable, simple in construction and the advantage installing low cost additional.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and beneficial effect clearer, this utility model provides drawings described below to illustrate:
Fig. 1 is the structural representation of this utility model disintegrating machine fluid power coupling apparatus excess temperature alarm device embodiment.
Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art can be better understood from this utility model and can be practiced, but illustrated embodiment is not as to restriction of the present utility model.
As it is shown in figure 1, be the structural representation of this utility model disintegrating machine fluid power coupling apparatus excess temperature alarm device embodiment.The disintegrating machine fluid power coupling apparatus excess temperature alarm device of the present embodiment, including the pressure sensitive device 2 being arranged on pump impeller 1 shell and the travel switch 4 being correspondingly arranged on motor base 3 with described pressure sensitive device 2, described pressure sensitive device 2 is provided with when high oil temperature the tentacle 5 stretching out and triggering described travel switch 4.
The disintegrating machine fluid power coupling apparatus excess temperature alarm device of the present embodiment; by arranging pressure sensitive device on pump impeller shell and being correspondingly arranged travel switch with pressure sensitive device; when oil temperature exceedes the scope of setting; the tentacle of pressure sensitive device stretches out and contacts cooperation with travel switch; and trigger travel switch; the alarm equipment alarm then electrically connected with travel switch; remind attendant can search problem reason with hard stop; the generation of Redeem large economic loss, and there is accurate, safe and reliable, simple in construction and the advantage installing low cost additional.
Further, the disintegrating machine fluid power coupling apparatus excess temperature alarm device of the present embodiment also includes that control system, described control system include that controller and alarm, described controller electrically connect with described travel switch 4.And described control system also includes the temperature sensor for detecting oil temperature and for controlling the flexible control circuit of described tentacle 5, described controller electrically connects with described temperature sensor and control circuit respectively.
During use, after oil temperature exceedes set point, control tentacle 5 and stretch out, trigger travel switch 4, and then controller controls alarm equipment alarm.
Embodiment described above is only the preferred embodiment lifted by absolutely proving this utility model, and protection domain of the present utility model is not limited to this.The equivalent that those skilled in the art are made on the basis of this utility model substitutes or conversion, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
