A test bench for oil injection pump and cooling pump

Abstract

The invention discloses a test bench for an oil injection pump and a cooling pump, which comprises a stainless steel ball valve, a vane type oil pump, a stainless steel cooler, a two-position two-way electromagnetic water valve, an air-conditioning switch, a first hydraulic oil filter, a pressure sensor, a second hydraulic Oil filter, turbine flow meter and pressure regulating switch. An oil outlet pipeline is set under the lower oil tank, and the oil outlet pipeline is connected to the working oil tank. A stainless steel ball valve is installed at the outlet of the oil outlet pipeline. The input end of the stainless steel cooler is connected to the two-position two-way electromagnetic water valve, and the end of the oil outlet pipeline close to the working oil tank is provided with a bypass, the bypass is equipped with a cold air switch, and the working oil tank is equipped with a cooling pump Test circuit and oil return pump test circuit; according to the test requirements of product components, the present invention verifies whether the performance of the oil injection and return pump meets the requirements through the measured parameters of the test. This product has accurate measurement, low cost, low noise, safety and environmental protection, and stable performance .

Description

technical field [0001] The invention belongs to the field of experimental equipment, and relates to a test bench, in particular to a test bench for an oil injection pump and a cooling pump. Background technique [0002] Injection, oil return pump and cooling pump are auxiliary oil supply, oil return, and cooling systems inside the product. On the one hand, the oil injection pump provides the required hydraulic energy for the product, and at the same time provides the lubricating oil required for lubrication and cooling; on the other hand In order to prevent the abnormal heating caused by the internal rotating parts of the product being in the lubricating oil and the scouring damage of the high-speed rotating parts, the oil return pump at the bottom of the product draws back the lubricating oil inside the shell and dissipates heat through the external radiator of the product. Guarantee the normal operation of the product; its performance directly affects the normal operation ...

Problems solved by technology

[0002] Injection, oil return pump and cooling pump are auxiliary oil supply, oil return, and cooling systems inside the product. On the one hand, the oil injection pump provides the required hydraulic energy for the product, and at the same time provides the lubricating oil required for lubrication and cooling; on the other hand In order to prevent the abnormal heating caused by the internal rotating parts of the product being in the lubricating oil and the scouring damage of the high-speed rotating parts, the oil return pump at the bottom of the product draws back the lubricating oil inside the shell and dissipates heat through the external radiator of the product. Guarantee the normal operation of the product; its performance directly affects the normal operation of the electrical system, the service life of electrical equipment, and even production efficiency; when the injection, oil return pump and cooling pump are in use, when the technical parameters change or are repaired After that, it must be checked and adjusted on the test bench to restore the original technical state. Therefore, the inspection and adjustment of the injection, oil return pump and cooling pump is an important common technology in production; most of the injection, oil return pumps and cooling pumps on the market The cooling pump test bench relies on imports, or the production cost is high, expensive, and the operation is complicated, difficult to master, and the working noise is loud, which is not conducive to the health of the staff. At present, it can no longer satisfy people's high precision, large range, corrosion resistance , explosion-proof and other performance requirements
