Abstract

The utility model provides a helical -lobe compressor's oil piping system is done in forced air cooling, its can solve adopt current external oil pump carry on the oil circuit circulation in advance lubricated mode can't satisfy the problem of operation requirement in winter. It includes compressor, gear box, overflow valve, lubricating -oil tank, oil pump, oil cooler, joins in marriage oil pipe and oil filter, its characterized in that: the oil pump is the built -in oil pump of system, the oil pump with the lubricating -oil tank tube coupling, the oil pump with be provided with the temperature -sensing valve between the oil cooler, the temperature -sensing valve respectively with the water spacer tube coupling of oil pump, oil cooler, compressor host computer.

Description

A kind of oil-way system of air cooling dry helical-lobe compressor
Technical field
The utility model relates to compressor oil circuit design field, especially relates to the oil circuit design field of air cooling dry helical-lobe compressor, is specially a kind of oil-way system of air cooling dry helical-lobe compressor.
Background technique
Dry screw compressor needs before starting to carry out oil circulation pre-lubrication by starting external oil pump more at every turn, oil body is influenced by environmental temperature, in the winter that room temperature is lower, because oil body is larger, oil pump need be opened for a long time, could by through for whole oil-way system after promoting lubricating oil temperature.And open the compressor initial stage, lubricant oil is as cold as lower temperature state by oil cooler again, and oil body becomes large again, and oil circulation is not smooth, and what lubricant oil can not be timely, enough is transported to each lubricating point, thus causes unit to damage; Therefore, the pre-lubrication time of existing oil-way system is grown and wastes energy, and reduces the fault-free interval time of unit.
Summary of the invention
For the problems referred to above, the utility model provides a kind of oil-way system of air cooling dry helical-lobe compressor, and it can solve and adopt existing external oil pump to carry out the problem that oil circulation pre-lubrication mode cannot meet use in winter requirement.
Its technological scheme is, it comprises compressor, gear-box, relief valve, lubricating oil tank, oil pump, oil cooler, oil distributing pipe and oil strainer, it is characterized in that: described oil pump is the built-in oil pump of system, described oil pump is connected with described lubricating oil tank pipeline, be provided with thermostat valve between described oil pump and described oil cooler, described thermostat valve is connected with the water spacer pipeline of described oil pump, oil cooler, compressor host respectively.
Further, described thermostat valve is connected with the water spacer pipeline of described compressor, and the water spacer of described compressor is connected with described relief valve, oil strainer and oil distributing pipe pipeline successively;
Further, described gear-box is connected with described lubricating oil tank pipeline.
The beneficial effects of the utility model are: it regulates overall lubricating oil temperature by the built-in oil pump of system and the thermostat valve be arranged between oil pump and oil cooler, guarantees that lubricating oil temperature can not be subject to low temperature environment impact and cause damage to unit, thus carry out the oil circulation prelubricated time, energy saving before saving the start of air-cooled screw compressor.
Accompanying drawing explanation
Fig. 1 is the oil-way system schematic diagram of a kind of air cooling dry helical-lobe compressor of the present utility model.
Embodiment
See Fig. 1, the oil-way system of a kind of air cooling dry helical-lobe compressor of the utility model, it comprises compressor host 1, gear-box 9, relief valve 2, lubricating oil tank 3, oil pump 5, oil cooler 6, oil distributing pipe 7 and oil strainer 8, wherein oil pump 5 is the built-in oil pump of system, oil pump 5 is connected with lubricating oil tank 3 pipeline, be provided with thermostat valve 4 between oil pump 5 and oil cooler 6, thermostat valve 4 is connected with the water spacer pipeline of oil pump 5, oil cooler 6, compressor host 1 respectively; The water spacer of compressor host 1 is connected with relief valve 2, oil strainer 8 and oil distributing pipe 7 pipeline successively; Gear-box 9 is connected with lubricating oil tank 3 pipeline.
Lubricant oil is delivered to thermostat valve 4 from lubricating oil tank 3 after oil pump 5 sucking-off pressurization, the adjustment temperature of thermostat valve 4 is arranged on T1 DEG C ~ T2 DEG C and T1 DEG C of < T2 DEG C, when the temperature of lubricant oil is more than T2 DEG C, thermostat valve 4 controls lubricant oil and all flows through the water spacer entering compressor host 1 after oil cooler 6 cools again; When the temperature of lubricant oil is between T1 DEG C ~ T2 DEG C, lubricant oil is divided into two-way by thermostat valve 4, a road flow into that oil cooler 6 cools, another road does not enter oil cooler 6 but directly shunting and with converge through the cooled lubricant oil of oil cooler 6 adjust overall lubricating oil temperature after flow directly into the water spacer of compressor host 1; When the temperature of lubricant oil is lower than T1 DEG C, then thermostat valve 4 controls the water spacer that lubricant oil all flows directly into compressor host 1; Adjust the temperature of the lubricant oil energy active balance compressor host housing of the low temperature flow after process through thermostat valve 4, prevent housing local temperature too high, stress is concentrated, and damages unit; The lubricant oil flowed out from the water spacer of compressor host 1 is after demand pressure adjusted to by relief valve 2, flow into oil strainer 8, then after oil distributing pipe 7 distributes, lubricant oil is transported to each lubricating point thus the bearing of lubricate compressors main frame 1, gear-box 9 and gear by oil strainer 8; And gear-box 9 is transported to lubricating oil tank 3 by concentrating after the lubricant oil merger of each lubricating point collection again, recycle.
