Background technique:

The cooling difference that has motor and compressor both by the natural gas engine compressor driven; The artificer often considers both in the lump; Select for use a bigger cooler of amount of cooling water to solve cooling problem between motor and compressor stage; Because the heat that produces when motor and compressor operating is different, the actual motion effect is unsatisfactory.As adopting the distributed type of cooling, motor utilizes different coolers with compressor, implements the cooling problem of reasonable this type of the solution compressor of Different control mode ability.

The model utility content:

The purpose of the utility model is exactly the above-mentioned defective that exists in the existing technology in order to solve, a kind of compressor distributed cooling system control gear that provides.

To achieve these goals, the utility model has adopted following technological scheme:

A kind of compressor distributed cooling system control gear; Comprise compressor, clutch and motor; Compressor 1 is connected with compressor cooler; Be provided with one group of compressor cooling blower in the compressor cooler, motor connects engine cooling apparatus, is provided with one group of engine cooling blower fan in the engine cooling apparatus; It is characterized in that: the final stage relief opening at compressor is provided with the compressor temperature transmitter; Be provided with the engine temperature transmitter at the engine cooling water outlet, compressor temperature transmitter and engine temperature transmitter are connected to the AI mouth of programmable controller respectively through signaling line, and programmable controller is connected with one group of compressor cooling blower and one group of engine cooling blower fan respectively through signaling line.

Said programmable controller changes the connection touch screen, to make things convenient for human-machine conversation control.

The advantage of the utility model is:

1, compressor and engine-cooling system are provided with separately, and control has automatically solved the technical barrier in the whole unit cooling, well for compressor cooling system of the same type provides technological auxilliary pad;

2, for adapting to the unit operation conditions, increase and decrease cooling motor operation platform number automatically, product is more energy-conservation.

3, cooling system all independently becomes sled, can put in the open, thereby reduce the construction area of user's compressor house, and user's up-front investment cost decreases.

4, under the situation of multiple compressors group networking; Relevant speciality personnel can monitor compressor through network whenever and wherever possible; In time understand the cooling situation of compressor and motor, the compressor bank automaticity is constantly upgraded, compressor each item technical parameter obtains strong guarantee.

Fig. 2 is that motor temperature control value is regulated and displayed map;

Fig. 3 is whether 4 typhoon machines move the selection picture.

Embodiment:

A kind of compressor distributed cooling system control gear as shown in Figure 1, that the utility model provides comprises compressor 1, clutch 2 and motor 3.Compressor 1 is connected with compressor cooler 8, is provided with one group of four compressor cooling blower (M9-M12), every 3kW in the compressor cooler 8.Motor 3 is connected with engine cooling apparatus 9, wherein is provided with 8 engine cooling blower fans (M1-M8), every 1.5kW, one group of M1, M2; One group of M3, M4; One group of M5, M6; One group of M7, M8 are divided into into 4 groups, every group of independence start and stop.

Final stage relief opening at compressor 1 is provided with compressor temperature transmitter 5; Be provided with engine temperature transmitter 4 at motor 3 cooling water outlets; Compressor temperature transmitter 5 and engine temperature transmitter 4 are connected to the AI mouth of programmable controller 7 respectively through signaling line, programmable controller PLC through signaling line respectively with one group of compressor cooling blower (M9-M12) and another group engine cooling blower fan (M1-M8) corresponding connection.In addition, programmable controller PLC is connected with touch screen 6.

In the utility model, the compressor bank active force is a natural gas engine, and the control of motor self is to form through related devices such as ignition controler, final controlling element, electronic speed regulator, starting motors; Motor drives compressor operation through clutch, through multistage compression rock gas is forced into 25MPa and charges into the aerating of air cylinder group steam supply car.

Compressor and motor adopt the multi fan system respectively, and engine cooling partly has 8 typhoon machines, and every 1.5kW is like figure, one group of M1, M2; One group of M3, M4; One group of M5, M6; One group of M7, M8 are divided into into 4 groups, every group of independence start and stop.The compressor cooling segment has 4 typhoon machines (M9-M12 among the figure, every 3kW).

Compressor distributed cooling system control gear, configurating programmable sequence controller SIEMENS S7-300 PLC and SIEMENS MP377 touch panel, whole unit simple to operate, reliable, automaticity is high.Under the normal situation of power supply, reach unattended state.

The cooling system function description

Consider the replacement in season, user's site environment temperature there are differences, and this cover control system adopts the brand-new design theory, makes compressor that stronger adaptability arranged.

1) engine-cooling system adopts independently cooler 9, and (M1-M9) form need not move whole blower fans when ambient air temperature is low, can drop into fan operation platform number less by many groups little blower fans.Compressor bank is in when operation, because the motor temperature rise ratio is higher, uses and organizes independently that cooler can solve the engine cooling problem flexibly, easily more.Gather engine outlet water temperature (like Fig. 1 through PLC; Engine outlet water temperature transmitter 4 detects); By PLC (7) analytical calculation, increase and decrease drops into fan operation platform number automatically, and we require to be provided with according to engine technology and when water-exit temperature surpasses 60 ℃ (can revise), move first group of blower fan automatically;, temperature drops into second group of blower fan, the 3rd group of blower fan when increasing progressively 5 ℃ successively automatically ..., and the like.

As shown in Figure 2; The numerical value that the A value compares with it for engine outlet water temperature (on touch screen, can revise); When water temperature surpasses 60 ℃, drop into first group of blower fan automatically, B value, C value, D value, E value increase progressively 5 ℃ through the PLC built-in command respectively successively among the figure on A value basis.When amount of cooling water surpasses the engine radiating amount, this group cooling blower of stopping transport respectively automatically when outlet temperature drops to A-F (B-F, C-F, D-F, E-F).The F value is the return difference value, and PLC contact competition when avoiding temperature to be in transition point is to improve the stability of a system.

2) many typhoons machine is also arranged in compressor cooling system, can open automatically according to the final compressor delivery temperature, blowing-out board number, when not needing more amount of cooling water, especially in the winter time, the blower fan of the suitable quantity of stopping transport has automatically also been saved simultaneously electric power.Consider the equipment that many typhoons machine possibly remain to be repaiied, the user also can select the fault blower fan not devote oneself to work automatically through touch screen (clicking the off key of corresponding blower fan) before start.

Seem simple design apparatus, the cooling system technical barrier of motor and compressor when but having solved the compressor bank operation has improved the ride quality of whole compressor group system, and the Flexible Control through PLC makes the compressor bank stable operation at normal condition.
