Abstract
The utility model discloses an airtight pump sealing device. An airtight ring (3) is arranged in the middle of a filler layer (2) above a pump bearing (1), dry gas inlet and outlet (4, 5) are arranged on corresponding sides of the airtight ring, the gas inlet (4) is communicated with an air source (6), the gas outlet (5) is communicated with a liquid tank (8) through a pipeline (7). Since the utility model adopts the airtight ring that can introduce dry gas, the airtight ring can prevent invasion of moisture in volatile corrosive gas or air effectively, prevent excessive corrosion to the pump shaft, extend period of usage of the pump, reduce production cost, and increase economic benefit.
Description
Technical field
The utility model belongs to the pumping machine equipment technical field, is specifically related to the air-tight pump seal arrangement that industry pumpings such as chemical industry, metallurgy contain the vertical pump use of volatile medium.
Background technique
Production field such as chemical industry, metallurgy, often need to carry some effumabilities and mordant medium, owing to form sealing system between pump-foot and the liquid storage tank, because of the difference of production technology, pressure difference in the liquid storage tank, may exist greater than, be equal to or less than three kinds of situations of atmospheric pressure.When the pressure in the sealing system equals atmospheric pressure, adopt the conventional seals filler to meet the demands; When the pressure in the sealing system during greater than atmospheric pressure, the volatility etchant gas will be discharged along the pump shaft gap, cause bearing to be subjected to corrosion failure and atmospheric pollution; When the pressure in the sealing system during less than atmospheric pressure, airborne moisture will enter sealing system along the pump shaft gap, mix with escaping gas to form corrosivity fog, and axle is caused corrosion failure.Therefore, back two kinds of situations must adopt more reliable sealing means to be damaged by corrosion to prevent pump shaft, prolong the working life of pump.Existing sealing configuration, to there being the situation of pressure reduction inside and outside the sealing system, its sealing effect is not good.For this reason, the design people has developed a kind of air-tight pump seal arrangement at the deficiencies in the prior art, has overcome the deficiency of conventional pump seal arrangement well, evidence, and effect is good.
The innovation and creation content
The purpose of this utility model is to provide a kind of simple in structure, air-tight pump seal arrangement that processing is easy.
The purpose of this utility model is achieved in that at pump bearing bottom packing layer middle part gas-tight ring is set, and the corresponding both sides of gas-tight ring are provided with dry gas respectively and import and export, and gas inlet is communicated with source of the gas, and gas outlet is communicated with in the liquid storage tank by pipeline.
The utility model is owing to adopted the gas-tight ring that can import dry gas, and the intrusion that can effectively stop volatility etchant gas or water in air to be divided prevents the excessive corrosion to pump shaft, prolongs the working life of pump, reduces production costs, and increases economic efficiency.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described, but the utility model is not limited to shown in the accompanying drawing.
Fig. 1 is an air-tight pump seal arrangement working state schematic representation of the present utility model;
Fig. 2 is an air-tight pump seal arrangement plane view;
Fig. 3 is that the AA of Fig. 2 is to view.
Embodiment
Fig. 1 shows working state of the present utility model, at pump bearing 1 bottom packing layer 2 middle parts gas-tight ring 3 is set, the corresponding both sides of gas-tight ring are provided with dry gas respectively and import and export 4,5, and gas inlet 4 is communicated with source of the gas 6, and gas outlet 5 is communicated with to go in the liquid storage tank 8 by pipeline 7.
Fig. 2-Fig. 3 shows the structure of gas-tight ring, and its ring cross section is " worker " font structure, and " worker " font structure both sides constitute inside and outside gas communication ring 9,10; The radial hole 11 that is uniformly distributed along the circumference, general 4-8 hole is depicted as 6 holes as embodiment's accompanying drawing.
The working principle of the utility model: by gas-tight ring dry gas is introduced in the seal arrangement, the dry gas that is full of sealing space, position stops the volatility etchant gas that moisture is invaded in sealing system or the sealing system in the atmosphere to corrode pump shaft along the pump shaft gap.
The utlity model has simple in structurely, reduced humid air and corrosive gas to the corruption of pump shaft Lose, improved the corrosion resistance of pump, the characteristics that prolong the service life of pump have overcome similar pump and have used Life-span is short, the drawback that environmental pollution is serious.
