Description
Technical field
The present invention relates to a kind of heating system, be specifically related to a kind of centralized lubrication pipeline heating system and using method.
Background technique
At low temperatures, the lubrication of equipment can select the lubricating grease of low temperature, although low temperature grease can ensure its usability in extremely low temperature, can reduce and become thickness more by Yin Wendu equally, even forming block.When such low temperature, lubricant grease in longer path and small aperture lubricating pipe is conveyed through time resistance increase, the situation of very easily intercepting, makes parts can not get effective lubrication.
The pipeline of centralized lubrication system comparatively thin (being generally 4mm-6mm) and long, branch line is many, and the power transporting lubricating grease is also disperseed, easily because the thickness of low temperature grease shines into intercepting of lubricating pipe.Dispersion is arranged in centralized lubrication pipeline space simultaneously, and the environment at the place of each branch line is different, is difficult to unification and heats each branch line simultaneously, and select more cold-resistant low-temperature lubrication grease also significantly can increase the purchase cost of oil product.
Summary of the invention
The object of the invention is for overcoming above-mentioned the deficiencies in the prior art; a kind of heating system for centralized lubrication pipeline is provided, the overall length scope of lubricating pipe is heated, and the heating equipment of at different levels, different lubricating pipe can be connected together; realize centrally connected power supply, unified control and scheduling co-design.
For achieving the above object, the present invention adopts following technical proposals:
For a heating system for centralized lubrication pipeline, comprise lubricant pump and lubricating oil path distributor; Described lubricant pump, lubricating oil path distributor are communicated by electric heating oil pipe I, and the output terminal of described distributor connects multiple lubricant oil by multiple electric heating oil pipe II squeezes into a little, correspondence output terminal squeezed into by a lubricant oil, and the outside that each lubricant oil is squeezed into a little is wound with resistance wire, described electric heating oil pipe I, the electrical heating net of electric heating oil pipe II, return wire are connected with contactor after all connecting with resistance wire, and described contactor is connected with circuit breaker; Described circuit breaker is by Power supply.
Described electric heating oil pipe I, electric heating oil pipe II include an oil pipe, a circle heating net is provided with in the outside of oil pipe, the thermal insulation layer of heating net outer wrapping insulation, insulation heat preservation layer is provided with return wire, and described heating net is connected by connecting ring with between return wire.

The lighting outlet of the connecting ring of described each electric heating oil pipe II is connected on a connecting terminal block, and makes the heating tape between pipeline form series connection by connecting terminal block by connecting terminal block.
Coil and a temperature detect switch (TDS) of connecting between circuit breaker of described contactor; Be responsible for detecting ambient temperature.After lower than setting temperature, it is electric that its switch motion makes contactor coil obtain, and connects netted power supply.
Described power sources in series timer, it is mainly setting heating cycle and time, and is connected with power supply, controls cycle and the time of power supply output.
Described circuit breaker, when the situation of being short-circuited, can deenergization in time, and feed back trouble signal.
For a using method for the heating system of lubricating pipe, step is as follows:
Step 1) lay lubricating pipe;
Step 2) thermal insulation layer of oil pipe is divested at the two ends of electric heating oil pipe, expose the heating net of internal layer;
Step 3) heating net that exposes at oil pipe is inserted in connecting ring, utilize connecting ring to make the heating net of oil pipe internal layer cause on the tenminal block of connecting ring, again the return wire of heating oil pipe is also accessed in the tenminal block of connecting ring simultaneously;
Step 4) squeeze into an end at lubricant oil, external resistance wire is linked on the tenminal block of connecting ring, utilizes the tenminal block of connecting ring to make the heating net on oil pipe be formed connect with external resistance wire, return wire;
Step 5) concentrate side at oil pipe line, by each oil circuit connecting ring upper connecting terminal by the heating net on oil pipe and return wire to picking out lead-in wire; And outside for lead-in wire access is gathered in connecting terminal block, make the electrical heating net on each lubricating pipe, return wire, external resistance wire formation series connection, and draw the total joint after series connection;
Step 6) the total joint after series connection is accessed power supply by contactor and circuit breaker;
Step 7) by the coils connected in series of temperature detect switch (TDS) and contactor, then access power supply in parallel, as determining whether the switch starting heating system;
Step 8) after all loops connect, measure the resistance value after the series connection of all electrical heating nets, then select the magnitude of voltage of heating power supply; (ac power supply uses adjustable transformer regulation output voltage, and direct current utilizes switch power to power to it.)
Step 9) adjustment Power supply parameter:
Heating time and cycle being set, can being set to heating cycle identical with lubricating the startup cycle; Heating time should in advance (at least advanced 10 minutes) and cover the time that lubrication starts, to realize the control of the temperature of the whole process to the preheating of oil product in pipeline before getting and fortune grease.
10) after connecting, when arriving the startup heating cycle of setting, power supply supplying power for outside, temperature detect switch (TDS) judges that whether environment temperature is lower than setting value simultaneously.If the temperature detected is lower than setting value, then connect contactor, make electrical energy transfer on heating net, whole heating system is powered.
The invention has the beneficial effects as follows:
1. the entire body heating adding thermal recovery of pair lubricating pipe, heating effect is even, also can access external heating wire flexibly simultaneously and heat greasing joint (or other devices).
2., for centralized lubrication system, multi-pipeline is formed and heats simultaneously, and can realize the heating that a power supply drives all branch lines, the efficiency of heating surface is high, and cost is low, and flexibility is good.
3. according to starting time of oil pump and cycle in advance and omnidistance oil circuit to be heated.
4. because the installation of entirety heating pipeline belongs to cascade, the uniform heat distribution that each branch line, each position produce.
5. according to the concrete condition of having laid rear line, heating power supply can be adjusted, adapt to the requirement under different situations more flexibly, also can meet the demand of pipeline transformation afterwards.
6. heating system only in temperature lower than when setting value and lubricant pump just can periodic startup before starting, saving power.
7. when heating system short circuit, make can disjunction power supply automatically, and reports to the police to control system.
Sum up: because centralized lubrication system branch line may much and very long, oil product stickiness increases when low temperature, and pass in process in long distance fortune and easily occur situations such as intercepting.And apply can be overall to pipeline after the heating pipe line of the design, omnibearingly to heat, avoid because low temperature is on the impact of lubrication system.
