Abstract
The utility model discloses a detection device for airtightness of a fuel tank. The detection device comprises a door-shaped support disposed at an edge of a water tank. A first cylinder is disposed on the top of a crossbeam of the door-shaped support and passes through a piston rod and the crossbeam to vertically face downward. A U-shaped support facing downward is fixed on an end portion of the piston rod, and a rectangular frame is fixed on an inner wall of the U-shaped support. A second cylinder is arranged in the center of an upper crossbeam of the rectangular frame, and a piston cylinder of the second cylinder passes through the upper crossbeam of the rectangular frame. An end portion of the piston cylinder is fixedly equipped with a sealing press cover that matches an oil inlet of the fuel tank. An air pump is disposed on one side of the door-shaped support, and an air outlet pipe of the air pump is communicated with an oil outlet of the fuel tank. The detection device is reasonable in structure and design. The cylinders are adopted to provide power so that the fuel tank is pressed downward and is immersed in the water tank, the oil inlet of the fuel tank is sealed, and the oil outlet of the fuel tank is communicated with an air inlet pipe, so that the detection device is convenient and fast in detection, allows labor intensity of workers to be minimized and enables the detection efficiency to be improved.
Description
Technical field:
The utility model relates to the fuel tank processing technique field, relates in particular to a kind of fuel tank air tight test device.
Background technology:
Fuel tank, the i.e. container of charge of oil.Refer in particular to the device that stores fuel oil on diesel engine or the gasoline engine driven machine.Fuel tank except oil storage, also plays effects such as bubble in heat radiation, the oil and water separation, precipitated impurities in hydraulic system.
Fuel tank generally is provided with two outlets: one is the fuel oil feeding port that directly can see, and one is to pack the outlet of fuel pump and fuel-metering device into.
Generally need carry out strict impermeability to it for the fuel tank that processes and detect, original employing manually is depressed into fuel tank to observe in the water tank and has or not bubble to produce, and it is big to detect interference, poor accuracy, and hand labor intensity is big.
The utility model content:
In order to remedy the prior art problem, the purpose of this utility model provides a kind of fuel tank air tight test device, and reasonable in design can conveniently detect the fuel tank impermeability, the accuracy height, and hand labor intensity reduces.
The technical solution of the utility model is as follows:
Fuel tank air tight test device, it is characterized in that: comprise the portal trestle that is installed on the water tank bead, the crossbeam top of portal trestle is equipped with first cylinder, first cylinder passes piston rod and passes crossbeam straight down, fixedly there is downward U-shaped frame the piston rod end, U-shaped frame inwall fixedly has rectangle frame, rectangle frame entablature middle part is provided with second cylinder, the second cylinder piston cylinder passes the rectangle frame entablature, fixedly there is the sealing gland that matches with the fuel tank oil-in piston cylinder end, described portal trestle one side is provided with air pump, and the escape pipe of air pump is connected with the oil-out of fuel tank.
Described fuel tank air tight test device is characterized in that: fixedly there is guide pole the both sides, crossbeam upper surface of described U-shaped frame, have pilot hole on the portal trestle crossbeam of guide pole opposite position.
The utility model has the advantages that:
The utility model reasonable in design provides power that fuel tank is pressed down by cylinder and is immersed in the water tank, fuel tank oil-in sealing simultaneously, and oil-out UNICOM draft tube, easy to detect quick, reduced hand labor intensity, improved detection efficiency.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Referring to Fig. 1:
Fuel tank air tight test device, comprise the portal trestle 2 that is installed on water tank 1 bead, the crossbeam top of portal trestle 2 is equipped with first cylinder 3, first cylinder 3 passes piston rod and passes crossbeam straight down, fixedly there is downward U-shaped frame 4 piston rod end, U-shaped frame 4 inwalls fixedly have rectangle frame 5, rectangle frame 5 entablatures middle part is provided with second cylinder 6, second cylinder, 6 piston cylinders pass the rectangle frame entablature, fixedly there is the sealing gland 7 that matches with the fuel tank oil-in piston cylinder end, portal trestle 2 one sides are provided with air pump 8, and the escape pipe 9 of air pump 8 is connected with the oil-out of fuel tank.
Fixedly there is guide pole 10 both sides, crossbeam upper surface of U-shaped frame 4, have pilot hole 11 on portal trestle 2 crossbeams of guide pole 10 opposite positions, guarantee to press down stability in the process.
Provide power that fuel tank is pressed down by first cylinder 3 and be immersed in the water tank 1, fuel tank oil-in sealing simultaneously, the escape pipe 9 of oil-out UNICOM air pump 8, easy to detect quick, reduced hand labor intensity, improved detection efficiency.
