Description
Technical field
The present invention relates to parallel water pump technical field, especially relate to a kind of seal performance test bench for water pump.
Background technique
Water pump will check the sealing of water pump before dispatching from the factory, and avoids the product export that there is mass defect.
At present, water pump is generally test sealing with water, and water test requires lower to testing installation, but also there is a lot of deficiency.If the test fixture of water pump is for a long time in water, frock is easily got rusty, and causes the turbidity test of water to decline, and need the water periodic replacement in water tank, cause water resource waste, testing apparatus needs periodic maintenance to maintain; During water test, a workman can only operate a testing apparatus, and the water above water pump drop by drop will be blown clean after having tested, testing efficiency is low, is unsuitable for typical products in mass production test; And existing water testing apparatus intelligent level is low.A kind of seal performance test bench for water pump disclosed in Chinese patent 201020302164.7, comprises frame, frame is connected with water tank, and described water tank inside is provided with base plate, and base plate top is connected with the measuring base can putting water pump, and base plate is also connected with drive unit; The top of measuring base is provided with pressing plate water pump can pushed down, and pressing plate is connected with drive unit.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of seal performance test bench for water pump, and low to reach the testing apparatus maintaining frequency, testing efficiency is high, is suitable for the object of typical products in mass production test.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of seal performance test bench for water pump, comprise stand, described stand is provided with frock lower plate and frock upper die plate, described frock lower plate is provided with sealing gasket for water-sealed pump one end and the vent being communicated with the water pump the other end, described frock upper die plate is provided with frock depression bar, and described stand bottom is provided with the air pump be connected with vent.
Described sealing gasket is pneumostop pad.
On described stand, corresponding frock lower plate position is provided with chute.
Described stand is provided with the control panel controlling air pump work.
The present invention compared with prior art, have the following advantages: adopt gas for detecting medium, water pump seamless is tested by the leakage rate detecting gas, control panel controls test, frock does not contact with water with water pump, and test terminates without the need to drying up process to test fixture and water pump, and the testing apparatus maintaining frequency is low, testing efficiency is high, is suitable for typical products in mass production test.
