Description
Technical field
The utility model relates to liquid-ring vacuum pumps to install equipment, be a kind of anti-freeze type liquid ring vacuum pumping system heat insulating and sound insulating
Cover.
Background technique
The equipment that liquid ring vacuum pumping system is to provide certain vacuum degree, in petrochemical industry extensive utilization.It is true by pendular ring
The working principle of sky pump is it is found that pump is to complete air-breathing exhaust process by certain thickness pendular ring, and pump chamber is answered before pump startup
There is a certain amount of working solution, working solution can be water or other liquid.Water ring during pump operation to keep constant, it is necessary to
Continuously supply water into pump.In petrochemical industry, liquid-ring vacuum pump often uses one to open one for a set of water system is shared, and
Standby pump can star the configuration mode devoted oneself to work at any time.In winter under cold conditions, for the liquid ring vacuum in outdoor arrangement
Pumping system, the static working solution of stand-by pump easily frozen, even results in the pump housing and frost crack pipe, causes production accident.For
Solve the problems, such as winter working solution circulating water pipework bursting by freezing, generally use following method: a kind of method is the work liquid pipe of drain pump
Line makes in the pump housing and pipeline of pump without working solution, and when starting refills working solution；A kind of method is to the pump housing and pipeline using companion
Hot measure；A kind of method is the workshop of setting band heating setting, and pump is installed improves working environment indoors.
In cold environment, each start-stop pump is intended to fill drain operation above-mentioned first method, cumbersome, once
It omits in printing or drain is not thorough, freezing accident can still occur for equipment, and be unable to satisfy the requirement that active and standby pump automatically switches starting,
Very big using being limited in modern industry, there are security risks.At present industrially, the most commonly used is second methods, that is, are directed to and set
Standby antifreezing heat insulation mainly uses steam tracing and electric tracing method.Since liquid-ring vacuum pump is total system equipment, equipment room
Pipeline pipe fitting valve is more, system complex and compact-sized.Using the method for steam tracing equipment, the arrangement of steam tracing pipeline
It is more difficult, and cause local temperature excessively high and local temperature deficiency, tracing steam pipeline and equipment and work there are dead angle and leak source
Pipeline adc also needs to keep the temperature cladding；If operational reliability depends greatly on heat preservation using electrically heat tracing method
Whether the installation and construction of heating tape are correct, it is also necessary to heat preservation cladding.Above two heat tracing mode main problem be dismounting it is inconvenient,
