Tsinfa 1500 tons hydraulic press machine using hands and feet linkage operation, convenient and simple. The hydraulic system uses electromagnetic directional valve, compact structure, safe and reliable, sensitive action. The machine frame of 1500 ton hydraulic press machine adopts all steel plate seamless welding, after vibration treatment, to ensure that the body is not deformed. The hydraulic press machine has independent hydraulic and electrical control system, which can realize two kinds of process of constant range and constant pressure. Hydraulic pump is the heart of the hydraulic press machine, today we will analyze the performance characteristics of the hydraulic pump.
The working pressure of hydraulic pump depends on the load of hydraulic press machine. If the load is zero, the working pressure of the hydraulic pump is zero. As the load increases, the working pressure of the hydraulic pump increases. The maximum working pressure of hydraulic pump is affected by the strength and service life of the pump. In order to prevent the hydraulic pump from being damaged due to the high pressure of the hydraulic press, measures must be taken to limit the high pressure. So in the actual operation of the hydraulic press machine, the highest pressure of the work shall not exceed the maximum pressure standard that the machine itself can bear. When the pressure of the oil suction chamber of the oil pump is too low, there will be insufficient oil suction. When the pressure of the oil suction chamber is lower than the air separation pressure of the oil, there will be cavitation phenomenon, resulting in gas erosion and noise of the internal components of the hydraulic pump, and the working pressure of the hydraulic press machine is unstable. Therefore, in order to ensure the normal operation of the hydraulic pump in addition to the pump mechanism design as far as possible to reduce the liquid resistance of the oil suction pipeline, but also should make the pump installation height does not exceed the allowable value range. And avoid suction oil filter and suction pipeline stroke too large pressure difference.
The hydraulic pump on the hydraulic press is usually divided into variable pump and quantitative pump. Under the condition of constant speed, the variable pump with variable output flow is the variable pump, and the quantitative pump with variable output flow is the quantitative pump. Simply speaking, after the speed of the quantitative pump is selected, its flow and pressure are determined and cannot be adjusted. Flow rate can only be changed according to adjusting speed. Variable pump output flow can be changed according to the pressure of the system, can automatically adjust the flow. Variable pump at high pressure output flow is small, at low pressure output flow is large. This saves the number of hydraulic components, simplifies the oil system, and reduces the heat generated by the oil. Disadvantages when the flow pulse is serious, the system pressure is not very stable, the service life of the pump is short, the procurement cost is high. Therefore, we will match more suitable hydraulic pumps according to the requirements of customers. Welcome to inquire.
