Description
Technical field:
The present invention relates to the cooling unit of vacuum pump unit, relate in particular to the cooling unit of flow-dividing vacuum pump assembly.
Background technique:
Rotary-vane vaccum pump is one of pumping equipment the most basic in the vacuum technique.Rotary-vane vaccum pump mostly is middle-size and small-size pump, and the branch of single-stage and twin-stage is arranged.So-called twin-stage is exactly structurally two single-stage pumps to be together in series.Bipolar rotary-vane vaccum pump (being commonly called as 2X type vacuum pump) is the gas that is used for extracting in the specific seal container, makes this container obtain the basic equipment of certain vacuum degree.The degree of vacuum of the vacuum pump twin-stage of equal specification is higher than single-stage.The twin-stage sliding vane rotary pump can directly obtain 6.0 * 10
-2The degree of vacuum that handkerchief is following, the fore pump that can be used as other vacuum equipments uses, and can supply industrial and mining enterprise such as metallurgy, chemical industry, oil, medicine, electrovacuum, atomic power, weaving, food, printing and dyeing, the usefulness of universities and colleges, scientific research institution's production, teaching, scientific research.The twin-stage sliding vane rotary pump mainly is made up of the pump housing, rotor, blade, end cap, spring etc.In in the pump housing chamber of twin-stage sliding vane rotary pump rotor is installed prejudicially, the cylindrical of rotor and pump housing inner cavity surface are tangent, and two rotating plate of band spring are housed in the rotor.During the rotor rotation, lean on the tension force of centrifugal force and spring that the top of rotating plate and the inwall in pump housing chamber are kept in touch, the rotor rotation drives rotating plate and slides along the pump chamber inwall.Since when work the rotating plate high speed rotating, the big calorimetric of friction-produced between rotating plate and the pump housing inner chamber, so need lower the temperature to the pump housing of vacuum pump with cooling water is carried out to keep it everything goes well with your work.Otherwise vacuum pump will be rapidly heated, and will cause vacuum pump to burn out when serious, has reduced the working life of vacuum pump.
At the solar module manufacturing shop, there are many equipment all to need to use vacuum, therefore must be equipped with the vacuum pump machine room provides the vacuum service for entire cell composing room, the vacuum pump machine room is made up of some vacuum pumps, in order to ensure vacuum pump energy proper functioning, must be equipped with independently water cooling system to every vacuum pump, be that each vacuum pump must be equipped with a cooling intake pipe and a hot water discharge pipe, so the cooling water inflow that the vacuum pump machine room is consumed is very big, operating cost height not only, and cause the water resources serious waste.
Summary of the invention:
The invention provides a kind of divided-flow vacuum pump unit water cooling device, it can provide water cooling water for many vacuum pumps simultaneously by a total water pipe, it can guarantee that sufficient cooling water is arranged in the vacuum pump when unexpected lack of water, prevent to cut off the water and cause the overheated scaling loss of vacuum pump, both prolong the working life of vacuum pump, saved water resources again.
The technical solution adopted in the present invention is:
Described divided-flow vacuum pump unit water cooling device, it comprises a main water pipeline, several vacuum pump cooling units and some master control valves, all vacuum pump cooling units are connected in turn on the main water pipeline, each vacuum pump cooling unit is all by water inlet branch road valve, the water inlet branch pipe(tube), vacuum pump, exit branch road and water outlet branch road valve are formed, the water inlet branch pipe(tube) is connected on the main water pipeline by water inlet branch road valve, the exit branch road is connected on the main water pipeline by water outlet branch road valve, water inlet branch pipe(tube) and exit branch road all interlink with the cooling water chamber of vacuum pump, the master control valve is installed on the main water pipeline in the serial connection mode, and each master control valve is arranged between the water inlet branch pipe(tube) and exit branch road and main water pipeline tie point of each vacuum pump cooling unit.
Its cooling procedure is as follows:
When all vacuum pumps in the vacuum pump machine room are worked simultaneously, because cooling water supply all the time in the main water pipeline, make all master control valves all be in closed condition, water inlet branch road valve in all vacuum pump cooling units and water outlet branch road valve all are in opening state, cooling water in the main water pipeline cools off by the cooling water chamber of water inlet branch road valve in the first vacuum pump cooling unit and water inlet branch pipe(tube) inflow vacuum pump earlier like this, the heat of vacuum pump flows into main water pipeline by exit branch road and water outlet branch road valve and mixes after water cooling, and then flow into second vacuum pump cooling unit, each vacuum pump carries out the water cooling cooling thereby the cooling water in the realization main water pipeline is flowed through step by step, just can cool to all vacuum pumps as long as the water temperature of the waterexit end of main water pipeline is hanged down 10 ℃～15 ℃ than the operating temperature of vacuum pump; When a few vacuum pumps do not need work or a certain to break down, the present invention still can cool off the vacuum pump unit of other work, at this moment, as long as open the master control valve corresponding, close in this unit water inlet branch road valve and water outlet branch road valve and get final product with the vacuum pump cooling unit.
This divided-flow vacuum pump unit water cooling device, as long as a cooling water inlet pipe road just can cool off all vacuum pumps step by step, make the cooling water of vacuum pump unit reusable, no matter several vacuum pump work it can both the vacuum pump of work effectively be cooled off, use checking through reality, the cooling device for vacuum pump of this structure is under the prerequisite that guarantees the vacuum pump proper functioning, the cooling water inflow that is consumed saves 60%～70% than prior art, the intensification that can either guarantee vacuum pump is lower than its staking-out work temperature, can significantly save water resources again.
