Abstract
A protection system of an acid unloading pump and an alkali unloading pump comprises a pump, a liquid inlet pipe, a liquid outlet pipe, a liquid inlet pipe valve, a liquid outlet pipe valve, a pressure water inlet pipe, a water inlet valve, a water outlet pipe and a water outlet valve. The liquid inlet pipe and the liquid outlet pipe are arranged on the pump, and the liquid inlet pipe valve and the liquid outlet pipe valve are arranged on the liquid inlet pipe and the liquid outlet pipe respectively. The pressure water inlet pipe is arranged on the liquid inlet pipe, the water inlet valve is arranged on the pressure water inlet pipe, the water outlet pipe is arranged on the liquid outlet pipe, and the water outlet valve is arranged on the water outlet pipe. The protection system of the acid unloading pump and the alkali unloading pump has the advantages that the pump, relative pipes and valves are not corroded by acid and alkali residual liquid, cleanness of the system is maintained, and pollution on work environment caused by volatile hydrochloric acid gas is reduced. Therefore, work load of operation maintenance staff is reduced, normal operation of the system is guaranteed, and finally service life of the pump is prolonged.
Description
Technical field:
The utility model relates to a kind of protective system, relates in particular to a kind of acid, alkali pump protective system of unloading.
Background technique:
Unloading sour pump is that hydrochloric acid liquid is got in the high-order basin by low level by boosting of pump.Unloading alkali pump is that alkali lye is got in the high-order basin by low level by boosting of pump.
Conventional unload acid, alkali pump system do not consider when operation or on the method for operation to the anti-corrosion protection of the system pipeline and the pump housing; unload like this after acid, alkali work finishes; can residual fraction acid in the import and export pipeline of pump and valve and in the pump housing, the alkali lye body; this part residual liquid has caused the corrosion of importing and exporting pipeline, valve and the pump housing; particularly can shorten the working life of pump; increase operation and maintenance cost, volatile hydrochloric acid gas also can pollute working environment simultaneously.
Be directed to how to prolong the working life of unloading acid, alkali pump, research direction has in the past just been carried out a large amount of tests and research on the material of pump body and flow passage components, makes the better corrosion of acid-and base-resisting of the pump housing, thereby prolongs the life-span of pump.But pump is in operation be protected, prolonged the working life of pump, the research of this respect seldom.
The model utility content:
It is a kind of simple in structure that the purpose of model utility is to provide, and what effectively prevent pump, valve, corrosive pipeline unloads acid, alkali pump protective system.
The purpose of this utility model is implemented by the following technical programs: a kind ofly unload acid; the alkali pump protective system; include pump; liquid inlet pipe; drain pipe; the liquid inlet pipe valve; the drain pipe valve; the pressure intake pipe; inlet valve; waste pipe and water discharging valve; described pump is provided with described liquid inlet pipe and described drain pipe; on described liquid inlet pipe and described drain pipe, be respectively equipped with described liquid inlet pipe valve and described drain pipe valve; on described liquid inlet pipe, be provided with described pressure intake pipe; on described pressure intake pipe, be provided with described inlet valve; on described drain pipe, be provided with described waste pipe, on described waste pipe, be provided with described water discharging valve.
Advantage: on liquid inlet pipe, be provided with pressure intake pipe and inlet valve, on drain pipe, be provided with waste pipe and water discharging valve, moment can rinse the acid, the alkali residual liquid that reach in associated conduit, the valve in the pump housing well, thereby reach the cleaning of associated conduit, valve in the maintenance pump housing, make pump and associated conduit, valve not by acid, the corrosion of alkali residual liquid, maintenance system cleaning, reduce the volatile salts acid gas and pollute working environment, thereby alleviate operating maintenance personnel's workload, the assurance system normally moves, and finally prolongs the working life of the pump housing.
Description of drawings:
Fig. 1 is an overall structure schematic representation of the present utility model.
Embodiment:
Embodiment 1:(is as shown in Figure 1) a kind of acid, alkali pump protective system of unloading; include pump 1, liquid inlet pipe 2, drain pipe 3, liquid inlet pipe valve 4, drain pipe valve 5, pressure intake pipe 6, inlet valve 7, waste pipe 8 and water discharging valve 9; pump 1 is provided with liquid inlet pipe 2 and drain pipe 3; on liquid inlet pipe 2 and drain pipe 3, be respectively equipped with liquid inlet pipe valve 4 and drain pipe valve 5; on liquid inlet pipe 2, be provided with pressure intake pipe 6; on pressure intake pipe 6, be provided with inlet valve 7; on drain pipe 3, be provided with waste pipe 8, on waste pipe 8, be provided with water discharging valve 9.
After the work of unloading acid, alkali pump is finished, close down and unload acid, alkali pump, open the inlet valve on the liquid inlet pipe upward pressure intake pipe, open the water discharging valve of waste pipe on the drain pipe simultaneously, moment can be with liquid inlet pipe, drain pipe, liquid inlet pipe valve, and acid, alkali residual liquid in the drain pipe valve and the pump housing are rinsed well, thereby keeps liquid inlet pipe, drain pipe, liquid inlet pipe valve, cleaning in the drain pipe valve and the pump housing makes pump not by acid, the corrosion of alkali residual liquid.
Claims (1)
1. one kind is unloaded acid; the alkali pump protective system; include pump; liquid inlet pipe; drain pipe; liquid inlet pipe valve and drain pipe valve; described pump is provided with described liquid inlet pipe and described drain pipe; on described liquid inlet pipe and described drain pipe, be respectively equipped with described liquid inlet pipe valve and described drain pipe valve; it is characterized in that: it also includes the pressure intake pipe; inlet valve; waste pipe and water discharging valve; on described liquid inlet pipe, be provided with described pressure intake pipe; on described pressure intake pipe, be provided with described inlet valve; on described drain pipe, be provided with described waste pipe, on described waste pipe, be provided with described water discharging valve.
