The invention discloses an adjustable constant voltage load testing device comprising gland nuts, glands, exhaust pipes, guide rods, constant voltage floating blocks and a constant voltage chamber; the exhaust pipes are fixedly connected to the constant voltage chamber; inner cavities of the exhaust pipes are communicated with an inner cavity of the constant voltage chamber; the guide rods are arranged in the exhaust pipes in a passing-through-mode along the axis center directions of the exhaust pipes; the bottom ends of the guide rods are in fixed connection with the bottom surface of the inner cavity of the constant voltage chamber; the guide rods are connected with the constant voltage floating blocks in a passing-through mode; the constant voltage floating blocks are placed in the exhaust pipes; the glands are connected with the guide rods in a passing-through mode; the gland nuts are connected to the guide rods in a threaded mode and press the glands against upper ports of the exhaust pipes; the glands seals the upper ports of the exhaust pipes; and the sidewalls of the exhaust pipes are provided with air exhaust openings. The adjustable constant voltage load testing device of the invention is simple in structure, low in cost and convenient to process. The occupied volume is small. The weight is light. The installation and adjusting are convenient. The pressure is constant, and can be adjusted according to needs.
Description
Technical field: [0001] The invention relates to an adjustable constant voltage load testing device. Background technique: [0002] When the blower is tested in the laboratory, the flow and outlet pressure are mainly controlled by adjusting the outlet valve to simulate the load situation. However, the valve is a variable resistance load. When it is necessary to test the automatic operation of the blower under constant pressure load conditions, it is often necessary to use a bulky gas buffer tank or find a constant pressure load site, and the test cost is relatively high. Invention content: [0003] The present invention provides an adjustable constant voltage load testing device in order to solve the above-mentioned problems in the prior art. [0004] The technical solutions adopted in the present invention include: an adjustable constant pressure load testing device, including a compression nut, a gland, an exhaust pipe, a guide rod, a constant pressure floating block an...
