Abstract
The utility model relates to a mechanical seal water circulation system for a plasticizer DOP (Dioctyl-Phthalate) production line. The mechanical seal water circulation system is characterized by comprising a mechanical seal water circulation tank, wherein the mechanical seal water circulation tank is communicated with a water feeding pipe; the lower end of the mechanical seal water circulation tank is communicated with a mechanical seal water outlet pipe; the mechanical seal water outlet pipe is at least connected with a set of mechanical seal water circulation pumps; the output ends of the mechanical seal water circulation pumps are connected with a mechanical seal water inlet main pipe; a remote pressure meter is mounted on the mechanical seal water inlet main pipe; the mechanical seal water inlet main pipe is connected with the pumps through branch pipes respectively; and the mechanical seal water outlet ends of the pumps are connected with a mechanical seal water return main pipe; and the mechanical seal water return main pipe is connected with the mechanical seal water circulation tank. According to the structure, the independent mechanical seal water circulation system is adopted instead of the original purchased external circulation water or domestic water flushing system, so that the expense is greatly reduced, a large amount of water resources are saved, about 100,000 tons of domestic water per year can be saved by one DOP production line through preliminary calculation, and the outstanding contributions are made for society and enterprises.
Description
Technical field
The utility model belongs to plasticizer DOP production line pump maintenance technology field, particularly relates to a kind of plasticizer DOP production line machine water shutoff circulatory system.
Background technique
The machine envelope of the pump that my company's plasticizer DOP production line is used all adopts end seal, need to wash at the water source preferably with water quality.Machine envelope sparge water is to adopt recirculated cooling water in original design, and this recirculated cooling water derives from circulating water and supplies with company, but circulating water quality is relatively poor, easily pump machine envelope is caused wearing and tearing, the working life of shortening machine envelope.For addressing the above problem, use Living Water instead as the machine envelope sparge water of pump temporarily, the wearing and tearing of machine envelope have been greatly reduced, but Living Water does not possess recycling condition, relief developing machine is honored as a queen and is just directly effluxed, cause a large amount of wastes of Living Water, increased the cost of product, reduced the competitive ability of product.
Summary of the invention
The utility model for the plasticizer DOP production line that solves the technical problem that exists in the known technology and a kind of simple in structure, easy to install, saving water resource is provided, reduces production costs with the machine water shutoff circulatory system.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of plasticizer DOP production line machine water shutoff circulatory system, it is characterized in that: this machine water shutoff circulatory system comprises machine water shutoff circulating tank, described machine water shutoff circulating tank is communicated with filler pipe, the lower end of described machine water shutoff circulating tank is communicated with machine water shutoff outlet pipe, described machine water shutoff outlet pipe connects one group of machine water shutoff recycle pump at least, described machine water shutoff circulation delivery side of pump junctor water shutoff water inlet manifold, on the described machine water shutoff water inlet manifold remote pressure gauge is installed, described machine water shutoff water inlet manifold connects pump by arm respectively, each pump machine water shutoff outlet end junctor water shutoff return main, described machine water shutoff return main junctor water shutoff circulating tank, be provided with cooling coil in the described machine water shutoff circulating tank, described cooling coil connects circulating cooling intake pipe and outlet pipe.
The utility model can also adopt following technical measures:
Described machine water shutoff circulating tank sidewall is provided with long-distance liquid-level meter.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, namely adopt the machine water shutoff circulatory system of setting up separately, replace the extraneous circulating water of original purchase or employing domestic water rinse-system, thereby greatly reduced spending, saved a large amount of water resourcess, to save 100,000 tons of Living Waters every year through a DOP production line of primary Calculation, thereby all make the contribution of high-lighting for society, for enterprise.
