Description

Technical Field

[0001] The utility model relates to the technical field of oil pump testing, in particular to an oil pump performance test bench. Background Art

[0002] An oil pump is a pump that is both lightweight and compact, and can be divided into three categories: in-line type, distributor type, and unit type. The oil pump needs a power source to operate, and the camshaft at its lower part is driven by the engine crankshaft gear.

[0003] However, in the existing oil pump device, when testing the oil pump placed on the test bench, personnel need to carry the oil pump to be tested up and down, which causes inconvenience for personnel during the test. Moreover, during the test, it is mostly directly tested by a flow meter without simulating the use environment, so it still needs to be improved. Content of the Utility Model

[0004] The purpose of the utility model is to provide an oil pump performance test bench to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an oil pump performance test bench, including a bearing base, a placement panel, and a test bench body.

[0006] A frame is welded to the inner wall of the bearing base, a driving mechanism is installed on the top surface of the frame, and a lead screw is arranged on the output shaft of the driving mechanism.

[0007] An oil pump body is arranged on the top surface of the placement panel.

[0008] A first oil storage tank and a second oil storage tank are installed on the top surface of the test bench body, and a flow meter is installed on the top surface of the test bench body through a mounting block.

[0009] A filter element is fitted and installed in the first oil storage tank, and a coil pipe is installed in the first oil storage tank.

[0010] Preferably, a fixing frame is welded to the top surface of the placement panel, a hydraulic rod is installed on the fixing frame, a clamping frame is arranged on the output shaft of the hydraulic rod, and the clamping frame limits the oil pump body. By arranging a clamping frame on the output shaft of the hydraulic rod, after the oil pump body to be tested is placed on the placement panel by personnel, the personnel can open the hydraulic rod to push the clamping frame to limit and clamp the oil pump body.

[0011] Preferably, a guiding block is welded to the rear end surface of the placement panel, the guiding block is sleeved in the frame, and the guiding block is installed on the lead screw through a thread. By limiting the guiding block sleeved in the frame, when limiting, the guiding block is installed on the lead screw through a thread, so that when personnel open the driving mechanism to drive the lead screw to rotate, the guiding block and the placement panel can be driven to move up and down according to the rotation direction of the lead screw.

[0012] Preferably, a support frame is welded to the bottom end surface of the test bench body, and the bottom end surface of the support frame is welded to the bearing base. The test bench body can be installed and fixed on the bearing base through the support frame.

[0013] Preferably, a chute plate is welded to the top end surface of the test bench body. An installation plate is slidably sleeved in the chute plate. An air inlet pipe is fixedly embedded in the installation plate, and a fan is installed in the air inlet pipe. By slidably sleeving the installation plate in the chute plate, personnel can push the installation plate to move left and right. When moving, the fan can be turned on to intake air through the air inlet pipe and discharge air through the bottom end surface.

[0014] Preferably, filling pipes are fixedly embedded in the top end surfaces of the first oil storage tank and the second oil storage tank, and the filling pipes are in liquid communication with the first oil storage tank and the second oil storage tank. The oil required for the oil pump test can be injected into the first oil storage tank and the second oil storage tank through the filling pipes for storage.

[0015] Preferably, return pipes are fixedly embedded in the front end surfaces of the first oil storage tank and the second oil storage tank, and liquid outlet pipes are fixedly embedded in the rear end surfaces of the first oil storage tank and the second oil storage tank. Through the return pipes and the liquid outlet pipes on the first oil storage tank and the second oil storage tank, the oil pump body can use an external pipeline to separately connect to the liquid outlet pipe on the first oil storage tank or the second oil storage tank to extract oil, and the flow meter can use an external pipeline to separately connect to the return pipe on the first oil storage tank or the second oil storage tank to discharge the extracted oil.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. The present utility model is provided with a placement panel. When personnel want to conduct a performance test on the oil pump body, since a clamping frame is equipped on the output shaft of the hydraulic rod, after the oil pump body to be tested is placed on the placement panel by the personnel, the hydraulic rod can be started to push the clamping frame to limit and clamp the oil pump body. After clamping, the limit is achieved by sleeving the guide block in the frame, and the guide block is installed on the lead screw by threads during limiting. In this way, personnel can start the driving mechanism to drive the lead screw to rotate, and according to the rotation direction of the lead screw, the guide block and the placement panel can be driven to move up and down, so that the oil pump body can reach the bottom end surface of the installation plate on the test bench body, thus avoiding the inconvenience of manually handling the oil pump body to be tested. In addition, during the test, since the installation plate is slidably sleeved in the chute plate, personnel can push the installation plate to move left and right. While moving, the fan can be started to intake air through the air inlet pipe and discharge air from the bottom end surface. When discharging air, the oil pump body can be cooled, and the air inlet pipe can also be removed to not cool the oil pump body, so as to test the working conditions of the oil pump body under cooled or normal temperature conditions.

[0018] 2. By providing the first oil storage tank and the second oil storage tank, when personnel conduct performance tests on the oil pump body, with the help of the return pipes and liquid outlet pipes on the first oil storage tank and the second oil storage tank, the oil pump body can use external pipelines and be separately connected to the liquid outlet pipes on the first oil storage tank or the second oil storage tank to extract oil. When extracting the oil in the first oil storage tank or the second oil storage tank, the second oil storage tank acts as a device for storing oil conventionally, while the first oil storage tank can be used to filter the oil reflux and can be externally connected with a pipeline for cooling water body on the coil pipe. In this way, the cooling water body can flow in the coil pipe to cool the oil in the first oil storage tank. Thus, the oil pump body can extract either the cooled and filtered oil or the conventional oil. During the extraction process, a discharge pipeline can also be externally connected to the oil pump body and connected to a flowmeter, enabling the flowmeter to test the flow rate of the liquid extracted by the oil pump body. And by connecting the pipeline externally connected to the flowmeter to the return pipe on the first oil storage tank or the second oil storage tank, the oil can flow back and circulate. In this way, the performance tests of different oils can be simulated to meet the later test and use requirements. Brief Description of the Drawings
