Abstract
The utility model relates to the technical field of an electric rotary drilling rig, in particular to an air conditioner independently operating on an electric rotary drilling rig. The air conditioner independently operating on an electric rotary drilling rig comprises a condenser, wherein one end of the condenser is connected with an electric air conditioner compressor, and the other end is connected with a liquid storage dryer; the electric air conditioner compressor is connected with an evaporator; the evaporator is connected with an expansion valve and a PTC (Positive Temperature Coefficient) heater; and the expansion valve is connected with the liquid storage dryer. Through the air conditioner independently operating on an electric rotary drilling rig, the driver of the rotary drilling rig can use the air conditioner without starting the rotary drilling rig; and the electric air conditioner compressor and an electric heater are used by taking electricity as the main power.
Description
Technical field
The utility model relates to the turn digging dynamoelectric drilling machine technical field, the air-conditioning of independent operating on especially a kind of turn digging dynamoelectric drilling machine.
Background technology
The refrigeration of the air-conditioning of existing rotary drilling rig and to heat all be to lean on the operation of engine to drive, refrigeration are the compressors of air conditioner that leans on the belt pulley of Diesel engine machine directly to drive; Heat is that the hot water that produces during through engine radiating heats.Air-conditioning can't use when engine is idle; If ato unit is opened air-conditioning system when rotary drilling rig is idle, not only wasted the energy, increased cost; And polluted environment; So generally can ato unit when rotary drilling rig is idle open air-conditioning, especially in cold and stern winter and extremely hot summer, bring great inconvenience to construction.
The utility model content
In order to overcome existing rotary drilling rig out-of-operation deficiency of air-conditioning when engine is idle, the utility model provides the air-conditioning of independent operating on a kind of turn digging dynamoelectric drilling machine.。
The utility model solves the technical scheme that its technical problem adopted: the air-conditioning of independent operating on a kind of turn digging dynamoelectric drilling machine; Comprise condenser; Said condenser one end connects the electric air-conditioning compressor; The other end connects drier receiver, and said connection electric air-conditioning compressor connects evaporimeter, and said evaporimeter connects expansion valve and is connected drier receiver with the said expansion valve of ptc heater.
The beneficial effect of the utility model is; The air-conditioning of independent operating can make the driver of rotary drilling rig under the situation that rotary drilling rig does not start, use air conditioner on this turn digging dynamoelectric drilling machine; Electricity consumption is used electric air-conditioning compressor and electric heater as major impetus.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model;
Among the figure 1, evaporimeter, 2, the electric air-conditioning compressor, 3, condenser, 4, drier receiver, 5, expansion valve, 6, ptc heater.
The specific embodiment
Like Fig. 1 is the structural representation of the utility model; The air-conditioning of independent operating on a kind of turn digging dynamoelectric drilling machine; Comprise condenser 3, said condenser 3 one ends connect electric air-conditioning compressor 2, and the other end connects drier receiver 4; Said connection electric air-conditioning compressor 2 connects evaporimeter 1, and said evaporimeter 1 connects expansion valve 5 and is connected drier receiver 4 with ptc heater 6 said expansion valves 5.
The air-conditioning of independent operating on this turn digging dynamoelectric drilling machine, the rapid expansion of moment volume that utilizes the cold-producing medium compression to discharge will absorb the principle refrigeration of great amount of heat energy.Its compressor is an electric air-conditioning compressor 2; Condenser 3 is installed in the place ahead of rotary drilling rig radiator; Directly driven by independent motor, and evaporimeter 1 is in driver's cabin the inside, the low pressure gaseous state cryogen flow of coming out from evaporimeter 1 during refrigeration work becomes high pressure-temperature gas through electric air-conditioning compressor 2; Become the liquid of high pressure low temperature through condenser 3 radiating tubes cooling cooling; Pass through drier receiver 4 dehumidifying and buffering again, with than pressure stable and flux and flow direction expansion valve 5, flow to evaporimeter 1 at last then through throttling and step-down.Refrigerant one is met environment under low pressure and is promptly evaporated, and absorbs great amount of heat energy.Air in the driver's cabin continues to flow through evaporimeter 1, drives indoor temperature and also just therefore reduces.Liquid cryogen is flowed through and is become low-pressure gas once more behind the evaporimeter 1, is inhaled into the periodic duty that electric air-conditioning compressor 2 carries out next time again.
By ptc heater 6 is arranged in driver's cabin, get to when heating when the cold and hot knob of panel when heating, it is open-minded to lead to ptc heater 6, by the airflow passes PCT heater 6 of blower fan or separate ventilation, sees off from air outlet again.And the air-conditioning system of all-electric independent operating; It is characterized in that replacing the compressor of air conditioner that former cause diesel engine belt drives by electric air-conditioning compressor 2; Ptc heater 6 is replaced little water tank; With blower fan independently air conditioner heat radiator is dispelled the heat, with electric air-conditioning compressor 2, independently blower fan directly is connected electric cabinet with ptc heater 6, electric cabinet directly links to each other with external power supply.
The air-conditioning of independent operating has been realized need not starting diesel engine and just can have been carried out the work of cooling and warming on this turn digging dynamoelectric drilling machine, has reduced energy resource consumption, and for the driver provides comfortable working environment, result of use is good.
