Background technology
Vavuum pump is as one of common equipment in industry, and user is to be entered according to the big of gas to flow in vavuum pump type selecting
Row estimation, but the influence of the flow and suction pressure, intake air temperature, supply water temperature etc. of gas is larger, such as the gas in colliery
Vavuum pump, the gaseous mixture scale of construction is that, according to local geologic structure, coal seam dialysis goes out gas amount, same as excavation depth is different
Local geology is also different with stratum, and the dialysis amount of gas is also different, and it can only be one general；With when ground temperature, water
Temperature, the change of atmospheric pressure, the gas amount of dialysis are also different, are also influenceed while vavuum pump is exerted oneself by these factors.
If gas flow does not reach design requirement, the chemical reaction amount of product is just directly influenced in terms of chemical industry, directly
Influence the yield and quality of product；If coal mine gas extraction can not be evacuated immediately, adit opening vacuum 15KPa is usually required that,
Gas density just rises, and the life to miner causes serious threat.
If estimating that tolerance is larger, then vavuum pump match power is just big, while a large amount of electric energy are consumed in vain also
Add the purchase cost of equipment；If vavuum pump type selecting is too small, tolerance does not reach design requirement, directly influences whether product
Quality and yield, serious goes back entail dangers to the life security of people.
Once although vavuum pump design typification, the performance of vavuum pump is just basic it was determined that can be by adjusting air inlet
Temperature, supply water temperature even adjust vacuum revolution speed to change the performance of vavuum pump by using variable-frequency motor, so that
Meet the actual demand of user.
Clear stipulaties are only made in current home and abroad to vavuum pump in measurement in lab tolerance, using fixed orifice plate or metering
Nozzle, such measurement apparatus can not move in-site measurement to again, it is necessary to which a kind of special device is measured.
Therefore provide a kind of device that can carry out in-site measurement vavuum pump tolerance to change vavuum pump according to actual needs
Configuration, adjustment influences the external condition of vavuum pump performance, so as to reach that configuration is reasonable, and the purpose for saving the energy seems particularly heavy
Will.
