Abstract
A pressure buffering device of a steam recovery pump is characterized by comprising a buffering tank, an air storage chamber and an air refilling valve. The buffering tank is connected with the air storage chamber, the air refilling valve is mounted on the air storage chamber, and the buffering tank is provided with a liquid inlet and a liquid outlet. The pressure buffering device of the steam recovery pump is compact in structure, reasonable in layout, simple to manufacture, low in manufacturing cost, small in equipment investment, and capable of effectively lowering violent vibration of the steam recovery pump during operation to a range capable of being controlled for safe production.
Description
Technical field
The utility model relates to a kind of pressure buffer device of Steam Recovery pump.
Background technique
Existing Steam Recovery pump is a kind of reciprocating pump, and when carrying out liquid compression, its liquid output end pressure fluctuation is very large when reciprocating pump, can cause the strenuous vibration of pipeline, and pipeline can't be fixed, and causes work normally to carry out, and needs frequent shut-down (breakdown) mainteance.
Summary of the invention
The purpose of this utility model is exactly the deficiency that overcomes above-mentioned phenomenon or prior art, provides a kind of pressure buffer device that is directly installed on the Steam Recovery pump, successful and simple in structure.
The utility model comprises knock out drum, gas storage chamber, aeration valve, and knock out drum is connected with gas storage chamber, and gas storage chamber is equipped with aeration valve, and knock out drum arranges liquid entering hole and liquid outlet.
The volume of described gas storage chamber greater than the knock out drum volume and greater than knock out drum to 1/2nd of boiler tubing volume summation.
Liquid entering hole of the present utility model is connected with the Steam Recovery delivery side of pump, and liquid outlet is connected with the water intake of steam boiler.
The Steam Recovery pump is in compression process, and liquid enters knock out drum from liquid entering hole, the pressure rise of air and liquid in tank, but air is easily compressed, so the tank internal pressure can be less than the delivery pressure of Steam Recovery pump; Steam Recovery pump pressure compression process finishes, and when beginning to suck liquid, the air in knock out drum can flow backwards to the Steam Recovery pump, this moment, the tank internal pressure descended, but because air expands, the tank internal pressure does not have large variation, reaches with this purpose that pot liquid pressure oscillation diminishes.
The utility model should be opened aeration valve and replenish air when shutting down maintenance.
The utlity model has following advantage:
1, this apparatus structure is compact, and is rationally distributed, makes simple cost low, and equipment investment is few.
2, by after supporting this device, strenuous vibration in the time of effectively reducing the Steam Recovery pump work is down to the scope that safety in production can be controlled.
Description of drawings
Fig. 1 is structural drawing of the present utility model.
In figure, 1, knock out drum, 2, gas storage chamber, 3, aeration valve, 4, liquid entering hole, 5, liquid outlet.
Embodiment
Shown in Figure 1, the utility model comprises knock out drum 1, gas storage chamber 2, aeration valve 3, and knock out drum 1 is connected with gas storage chamber 2, and gas storage chamber 2 is equipped with aeration valve 3, and knock out drum 1 arranges liquid entering hole 4 and liquid outlet 5.
The volume of described gas storage chamber 2 greater than knock out drum 1 volume and greater than knock out drum to 1/2nd of boiler tubing volume summation.
Claims (2)
1. the pressure buffer device of a Steam Recovery pump, is characterized in that comprising knock out drum, gas storage chamber, aeration valve, and knock out drum is connected with gas storage chamber, and gas storage chamber is equipped with aeration valve, and knock out drum arranges liquid entering hole and liquid outlet.
2. the pressure buffer device of a kind of Steam Recovery pump according to claim 1, the volume that it is characterized in that described gas storage chamber greater than the knock out drum volume and greater than knock out drum to 1/2nd of boiler tubing volume summation.
