Description
Technical field
The utility model relates to and belongs to automatic control technology field, specifically, is a kind of diaphragm type compressor lubricant oil heating automatic controller.
Background technique
Membrane compressor is a kind of positive displacement compressor of special construction, has the advantages that compression ratio is large, good airproof performance, pressurized gas are not polluted by lubricant oil and other solid impurity.Usually, diaphragm type compressor is primarily of compositions such as driving mechanism, cylinder part, lubricating oil system, air pipe parts, crankcase components.According to the working principle of membrane compressor, hydraulic oil in membrane compresses Oil cylinder is augmented by compensating oil pump in lubricating oil system, from running of just starting shooting, could normally work, to gas boosting until fill hydraulic oil in cylinder body to during 1.1 ~ 1.15 times of rated discharge pressures of required exhaust pressure.
Traditional diaphragm type compressor does not have lubricant oil to heat automatic controller, in this case, particularly during winter, at some northern areas, temperature is lower, in crankcase, oil body increases, lubricating oil flow is weak, oil require is filled for a long time like this from equipment oil cylinder of just having started shooting, even cannot augment full, do not have q.s lubricant film press can not to gas boosting, cannot normally work, usage requirement can not be met, in addition, in oil cylinder, low on fuel cannot form desired oil pressure and also can cause discontinuity to diaphragm, load increases, long-time use, reduce the defects such as diaphragm working life.
Model utility content
For above-mentioned prior art Problems existing, the utility model provides a kind of diaphragm type compressor lubricant oil to heat automatic controller, can detect lubricating oil temperature and timely to its heating, reaches compressor and normally to work required temperature.
To achieve these goals, the technological scheme that the utility model provides is, a kind of diaphragm type compressor lubricant oil heating automatic controller, comprise crankcase body, bimetallic thermometer, temperature transmitter, electric heater and PLC control circuit, crankcase body is built with lubricant oil, electric heater is arranged on crankcase side wall, the heating pipe of electric heater extend into below the lubricant oil liquid level in crankcase body, bimetallic thermometer and temperature transmitter are arranged on crankcase body front, the bimetallic temperature sensing element of bimetallic thermometer extend into below the lubricant oil liquid level in crankcase body, the sensor of temperature transmitter extend into below the lubricant oil liquid level in crankcase body, temperature transmitter is electrically connected with PLC control circuit.
In the technical program, the effect of crankcase body is splendid attire lubricant oil and provides a transit space for lubrication oil circulation process during compressor operating; The effect of bimetallic thermometer is the lubricating oil temperature in detection crankcase body; The effect of temperature transmitter physical measurement signal or generic telecommunication number is converted to standard electric signal export or can export in communications protocol mode, and the lubricating oil temperature measurement signal here detected by bimetallic thermometer exactly changes into standard signal and is transferred in PLC control circuit; The effect of electric heater is heated the lubricant oil of stickiness large fluidity difference in crankcase body; PLC control circuit is a kind of control circuit based on digital calculation operation, can receive the standard signal that temperature transmitter sends, also can send work order to electric heater.
Further improvement of the utility model is, anti-explosion electric heater selected by electric heater, and anti-explosion electric heater mainly adopts cluster type tubulose electric heating original paper, and volume is little, power is large; Also have that thermal response is fast, temperature-controlled precision is high, integrated heat efficiency is high, the advantage such as applied range, strong adaptability.
Further improvement of the utility model is, integrated bimetallic thermometer selected by bimetallic thermometer, integration bimetallic thermometer by the signal is far passed function of thermal resistor or thermocouple and bimetallic thermometer on the spot deixis combine, it can meet on-the-spot thermometric demand, also remote transmission demand can be met, therefore can no longer serviceability temperature transmitter, reduce cost of production.
The beneficial effects of the utility model are: detect lubricating oil temperature in time during start and be heated to preference temperature to subzero oil, effectively prevent because lubricating oil temperature is low, viscosity be large, poor fluidity and after the diaphragm type compressor start that causes oil cylinder can not fill oil for a long time, then make diaphragm type compressor not meet usage requirement and reduce the hidden danger in diaphragm working life, fix a breakdown in time, guarantee the normal operation of diaphragm type compressor.
Accompanying drawing explanation
Fig. 1 is structural scheme of mechanism of the present utility model.
In figure, 1-temperature transmitter, 2-bimetallic thermometer, 3-crankcase body, 4-electric heater.
Embodiment
In order to deepen, to understanding of the present utility model, to be described in further detail the utility model below in conjunction with drawings and Examples, this embodiment, only for explaining the utility model, not forming protection domain of the present utility model and limiting.
As shown in Figure 1, a kind of diaphragm type compressor lubricant oil heating automatic controller, comprise crankcase body 3, bimetallic thermometer 2, temperature transmitter 1, electric heater 4 and PLC control circuit, crankcase body 3 is built with lubricant oil, electric heater 4 is arranged on crankcase side wall, the heating pipe of electric heater 4 extend into below the lubricant oil liquid level in crankcase body 3, bimetallic thermometer 2 and temperature transmitter 1 are arranged on crankcase body 3 front, the bimetallic temperature sensing element of bimetallic thermometer 2 extend into below the lubricant oil liquid level in crankcase body 3, the sensor of temperature transmitter 1 extend into below the lubricant oil liquid level in crankcase body 3, temperature transmitter 1 is electrically connected with PLC control circuit.
Electric heater 4 in present embodiment can choice for use anti-explosion electric heater, bimetallic thermometer 2 can select integrated bimetallic thermometer, the use of integration bimetallic thermometer, by the signal is far passed function of thermal resistor or thermocouple and bimetallic thermometer on the spot deixis combine, wherein, the signal is far passed function instead of the effect of temperature transmitter 1 in the present embodiment, therefore can no longer serviceability temperature transmitter 1, reduces cost of production.
The specific works flow process of present embodiment is, during diaphragm type compressor starting up, operator can observe the lubricating oil temperature in crankcase body 3 by bimetallic thermometer 2, simultaneous temperature transmitter 1 detects that corresponding oil temperature is converted into electrical signal and passes to PLC control circuit in real time, program according to setting: when oil temperature being detected lower than 0 ° of C, PLC control circuit report to the police not directly start mair motor and give electric heater 4 one signals, start electric heater 4 pairs of lubricant oil heating, until during 10 ° of C, PLC control circuit is by the feedback signal instruction electric heater 4 again of temperature transmitter 1, stop the heating to oil, then mair motor is started, the very fast normal work of molding machine, when temperature transmitter 1 detects lubricating oil temperature higher than 0 ° of C, do not start electric heater 4, main electrical engine direct start up work.
More than show and describe basic principle of the present utility model, major character and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
