The utility model relates to a kind of fan performance not blowing-out of mine system and device when measuring.
Background technique
According to the regulation of the 7th section of " safety regulations in coal mine " (2010 editions) the 100 twenty-one provision, before the new main blower fan of installing comes into operation, must carry out 1 fan performance and measure, carried out 1 performance measurement in later per 5 years at least.
Fan performance is measured by the mechanism with Safety of Coal Mine Production detection check qualification and is carried out at colliery scene.
The main fan performance of present most of mine is measured, and all under the situation that blower fan blowing-out, mine stop production, carries out, and has had a strong impact on mine output.
New Built Mine is according to coal industry mine relevant design standard; Adopt equipment such as plate air door, venetian blind horizontal checkout air door, open-close type air door winch; Not blowing-out of mine system when being provided with main fan performance and measuring, but civilwork engineering quantity is big, equipment has high input, and particularly louvre type horizontal checkout air door cost cost height and installation requirement are high; The whole system complicated operation, automaticity is low.
The model utility content
The utility model technical issues that need to address just are to overcome the defective of existing technology; Not blowing-out of mine system and device when providing a kind of fan performance to measure; The cooperation of its utilization electrically ventilating butterfly valve and electric-powered shutter is carried out the air channel to the main blower fan of 2 covers and is switched, and realizes that 1 cover uses, 1 cover is subsequent use.Standby fan is carried out performance measurement, and simple to operate, testing precision is high, has reduced civilwork engineering quantity, the cost cost is lower.
For addressing the above problem, the utility model adopts following technological scheme:
Not blowing-out of mine system and device when the utility model provides a kind of fan performance to measure; Comprise I blower ventilation system and II blower ventilation system; I blower ventilation system is identical with II blower ventilation system architecture; I blower ventilation system comprises I blower fan slip ring and I electrically ventilating butterfly valve, and I electrically ventilating butterfly valve front end is connected with the I slip ring, and rear end and I number are connected air duct and link to each other; The side of I number connection air duct is connected with the I electric-powered shutter, and the rear end of I number connection air duct connects the I blower fan; II blower ventilation system comprises II blower fan slip ring and II electrically ventilating butterfly valve; II electrically ventilating butterfly valve front end is connected with the II slip ring; Rear end and II number are connected air duct and link to each other; The side of II number connection air duct is connected with the II electric-powered shutter, and the rear end of II number connection air duct connects the II blower fan.
Not blowing-out of mine system and device when the utility model provides a kind of fan performance to measure, the cooperation of its utilization electrically ventilating butterfly valve and electric-powered shutter carry out the air channel to 2 cover blower fans and switch, and realize that 1 cover uses, 1 cover is subsequent use.
When the I blower fan is carried out performance measurement, close the I Fan butterfly valve, open the II Fan butterfly valve, and make II blower fan electric-powered shutter (normally off) be in closed condition, start the II blower fan and make its proper functioning.Open I blower fan electric-powered shutter this moment, control through detecting the air quantity of blower fan, fan condition is regulated, accomplish the I fan performance and measure through the aperture size of regulating electric-powered shutter.Specific operation are crawl I blower fan electric-powered shutter button; Make the ascending unlatching of window of I blower fan electric-powered shutter, thereby change the ventilation system resistance, the I fan condition is regulated; In the full flow scope, select measuring point to be greater than 7, accomplish the I fan performance and measure.
It is as the same that the II blower fan is carried out the performance measurement operation.
The utility model utilizes the supporting automatical control system of blower fan that electrically ventilating butterfly valve, electric-powered shutter are carried out switch control, and automaticity is high, has improved working efficiency, has good economic benefit and social benefit.
