Abstract
The utility model relates to screw pump heating and heat-insulating device, and its feature comprises the calandria be made up of carbon fiber heating wire, and oil resistant, waterproof, fire-retardant, anticorrosion, antistatic, outside are provided with and are fixedly connected with cingulum muff and portable power supply voltage control case.Adopt the technical solution of the utility model, the 36V safe voltage exported with portable power supply voltage control case is carried out heating for power supply and is incubated, by being fixedly connected with cingulum, heating and thermal insulation cover is closely wrapped on screw pump housing, thus the liquid fast melt freezed in guarantee screw pump, device normally starts.It is fast that the utility model has heating rate, and the not starting the arc of breaking, apparatus surface covers completely, lightweight easy for installation, can shirk the advantage of installation and maintenance.
Description
Technical field
The utility model relates to a kind of screw pump heating protection device, especially carries the heating and heat-insulating device of the screw pump of liquid.
Background technology
Winter, outdoor work environment temperature in Northern Part of China was low, and in screw pump, liquid easily freezes at low temperatures, caused device to start.In order to ensure that the fast quick-recovery of frozen device starts, now adopt the mode that simple electric blanket heats.Although be easy to realize, this method also exists problems.The heating source that electric blanket provides is conventional, electric-resistance silk, quantity of heat production is lower, heating rate is slow, the thawing of frozen liquid cannot be ensured, cannot the startup of Quick recovery device, and the resistance wire life-span of electric blanket is short, and recycling rate of waterused is lower, broken string produces electric arc, brings potential safety hazard and significant limitation to use.
Summary of the invention
Goal of the invention
Technical problem to be solved in the utility model is to provide a kind of for screw pump, does not destroy its globality, and uses that a kind of heating efficiency is high, high insulating effect, and easy for installation, and explosion-proof performance is good, realizes the screw pump heating and heat-insulating device of safety in production.
Technical scheme
Screw pump heating and heat-insulating device, the 36 volts of power supplys exported by portable power supply voltage control case provide electric power.Its inside is overlapped two parts formed by single 2 meters to 3.5 meters carbon fiber heating wires in parallel and oil resistant, waterproof, fire-retardant, anticorrosion, antistatic temperature preservation, is provided with and is fixedly connected with cingulum, make it closely be wrapped in screw pump outside in muff outside.Power and the carbon fiber heating wire quantity of heating and heat-insulating device are determined, every square metre 600 watts to 1000 watts according to the size of the surface area of screw pump.The explosion-protection equipment that fiber heater wire and plain conductor joint adopt is by heat-shrink tube, and little copper pipe and epoxy resin are formed.
Advantage and effect
The advantage that the utility model technology is compared with prior art had is:
(1) heating rate is fast, no-load condition lower three minutes Nei Keda 150 DEG C;
(2) to break the not starting the arc, effectively stop the generation of fire;
(3) electric heating conversion ratio is high, saves energy, and calandria is a kind of full black matrix material, and improve 30% than metallic resistance silk heat generation rate, electric heating conversion efficiency is greater than 99%;
(4) safe voltage 36 volts, guarantees the personal safety of site operation personnel.

Embodiment
Below in conjunction with accompanying drawing, the utility model patent is described in detail.
A kind of screw pump heating and heat-insulating device, the 36 volts of power supplys exported by portable power supply voltage control (6) case provide electric power.Comprise the heating and thermal insulation body that can closely be wrapped in outside screw pump of calandria and muff formation, the outside of muff is provided with and is fixedly connected with cingulum, is closely wrapped on screw pump housing by heating and thermal insulation cover by being fixedly connected with cingulum.
Calandria is made up of carbon fiber heating wire (1) parallel connection of joint length at 2 meters to 3.5 meters, fiber heater wire (1) and plain conductor (8) joint adopt explosion-protection equipment (7), by heat-shrink tube (11), little copper pipe (10) and epoxy resin (9) are filled and are formed, and calandria utilizes carbon fiber heating wire to heat in the inner side near screw pump wall of muff.
Muff is made up of oil resistant, waterproof, waterproof, fire-retardant, etch-proof internal layer (5) and skin (3), and heat-insulation layer (4) is made up of resistant to elevated temperatures Polyester Fibers.The power of heating and thermal insulation body and fiber number are determined, every square metre 600 watts to 1000 watts according to the size of the surface area of screw pump.
Claims (4)
1. screw pump heating and heat-insulating device, it is characterized in that: the heating and heat-insulating device be closely wrapped in outside screw pump comprises calandria, oil resistant, waterproof, fire-retardant, anticorrosion, antistatic, outside are provided with and are fixedly connected with cingulum muff and portable power supply voltage control case (6).
