How to choose the oil pump when designing the oil pressure machine?
In the design of the oil pressure machine's oil pressure system, the reasonable selection of the oil pressure pump port should be based on the required operation: I conditions are usually selected from gear pump, blade pump or plunger pump according to the host operation, power size and system performance requirements. The type starts. Oil compressor manufacturers are widely used in spare parts processing of the automotive industry and the shape, correction, correction and shoes, handbags, rubber, molds, shafts, and axis parts of various products in various industries. The bending, pressure printing, and sleeve stretch of board parts, washing machines, electric motors, automotive motors, air -conditioning motors, miniature motors, servo motors, wheel manufacturing, shock absorbers, motorcycles and machinery and other industries. The 300 -ton oil compressor is basically invested, covering the area of small area, and its daily maintenance and maintenance are simple. Fast oil compressor uses liquid pressure to transmit power and control a transmission method. The hydraulic device is a hydraulic pump, a hydraulic cylinder (hydraulic motor, etc.), hydraulic control valve and hydraulic auxiliary element. Then, the maximum work pressure and maximum traffic obtained by the statistical calculation determine the specific specifications and models of lice. At the same time, quantitative or variables, primary motivation types, speed, volume efficiency, total efficiency, self -absorption, noise and other factors. These factors are usually reflected in product samples or manuals, and they should be carefully studied one by one. Unknown consulted goods, source units or manufacturers. In the product sample of the oil pressure machine oil pump, the rated pressure and maximum pressure value are given, and the oil pressure pump should be selected according to the rated pressure value. Only in the use of temporary overloads or within the scope specified by the sample, the oil pressure pump that is at the highest pressure value is allowed, otherwise the efficiency and life of the oil pressure pump will be affected. J represents the rated flow (or displacement) value of each pump in the oil pressure pump product sample. When selecting the hydraulic pump, it must be ensured that the pump complies with the specified speed of the rated flow, otherwise the required flow will be unavailable. It is necessary to avoid changing the speed of the oil pump by anymore as much as possible, because otherwise it will not ensure sufficient volume efficiency and wear accelerated pump wear.
