Abstract
The invention relates to a screw rod pump heating and heat preservation device. Under a winter outdoor environment, liquid in a screw rod pump is easy to freeze and the device cannot be started. The screw rod pump heating and heat preservation device is composed of a heating and heat preservation body and a hand-lifting power supply variable-voltage control cabinet. With the adoption of the technical scheme, 36V safety voltage output by the hand-lifting power supply variable-voltage control cabinet is used as a power supply and is used for heating and preserving heat, so that the liquid frozen in the screw rod pump is rapidly melted and the device can be normally started. The screw rod pump heating and heat preservation device has the advantages that the temperature rising speed is rapid, electric arc is not generated when a line is broken, the surface of the device is completely covered, the weight is light, the installation is convenient, and the device can be detached, mounted and maintained.
Description
Technical field
Patent of the present invention 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
Patent of the present invention technical problem to be solved 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 made up of heater wire and muff two parts, and heater wire utilizes carbon fiber heating wire to heat in the inner side near screw pump wall of muff.Be provided with in muff outside and be fixedly connected with cingulum, make it closely be wrapped in screw pump outside.
Advantage and effect
The advantage that patented technology of the present invention 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.
