Pump variable pump, Qingdao variable pump, hydraulic preferred crystal Chong

Variable hydraulic variable displacement pump and variable institutions have varied excavator motor variable displacement pump, which can be divided into two categories: the first category divided according to type manually operated, motorized, electric, hydraulic and electro-hydraulic proportional control control, signal control variables are applied; the second by adjusting the way to distinguish, which automatically controls the pump (motor) basic parameters (including pressure, flow, power, etc.) according to certain rules change variable pump maintenance, such as constant power, constant pressure, constant flow, etc. . One revolution each plunger and its amount of oil discharged to go stroke related to the larger stroke of the larger amount of oil is discharged, and the stroke of the plunger depends on the angle of the swash plate when the swash plate angle A greater the plunger the greater the pump stroke the greater the amount of oil discharged. So changing the swash plate angle can change the pump displacement. Variable pump swash plate angle is controlled by the servo piston, the servo piston moves to the left when the big end of the servo piston oil pressure, pushing the swash plate moves to the left, so that the angle A smaller mixer pump variable stroke smaller row quantity is small. Control of critical control servo piston pump displacement becomes, currently there are many factors to control it, such as system pressure, back to the oil pressure valve and electronic control devices. Pump variable pump, variable pump Qingdao, Jinan Jing Jing Chong Chong hydraulic preferred by hydraulic machinery Limited. Jinan Jing Chong Hydraulic Machinery Co., Ltd.
