Abstract
The utility model discloses a control system of a hydro-viscous speed-adjusting clutch. The control system consists of a motor, a frequency converter, a three-screw pump, a plate-type throttle valve, and a valve seat. The frequency converter is connected with a control terminal of the motor. The three-screw pump is connected with an output shaft of the motor. An oil filter is mounted on an oil inlet of an oil inlet pipe of the three-screw pump. An oil outlet pipe of the three-screw pump is connected with an oil inlet of the valve seat. An oil outlet of the valve seat is respectively connected with a control oil pipe and all control instruments of a main machine of the hydro-viscous speed-adjusting clutch. An oil return opening of the valve seat is connected with an oil tank. The plate-type throttle valve is mounted between the oil inlet and the oil return opening of the valve seat. The control system adjusts the oil supply flow of the three-screw pump by adjusting the revolving speed of the motor through the frequency converter so that the control system can control the oil pressure level of hydraulic oil input into the main machine and the aim of adjusting the speed of the hydro-viscous speed-adjusting clutch can be realized. The valve seat used in the control system is uneasy to block off and is low in requirements for cleanliness of the hydraulic oil, high in reliability, simple in structure, stable and reliable in operation, and low in cost.
Description
Technical field
The utility model relates to a kind of control system of hydro viscous variable speed drive.
Background technique
Hydro viscous variable speed drive also claims that slip clutch is a kind of novel stepless speed regulating drive device; Has good speed adjusting performance; It has significant advantage in the speed governing and the energy-saving field of high-power blower and water pump, has been widely used in industries such as oil, electric power, chemical industry, metallurgy, mine, city water supply and sewage.Its control system is the important composition parts in the complete machine, is to realize the adjusting to the hydro viscous variable speed drive output speed through changing control oil pressure size, reaches the purpose of variable speed energy saving.The control system of existing hydro viscous variable speed drive adopts electricity liquid ratio relief valve to regulate the pressure of control hydraulic oil mostly, realizes the purpose of speed governing.The electricity liquid ratio relief valve complex structure, processing technology is complicated, and is high to the turbidity test requirement of hydraulic oil, in case stop up, the pressure regulation instability will occur even regulate malfunctioning phenomenon, and poor reliability is brought economically loss and inconvenience to the user.The electric-hydraulic proportion overflow needs the gear pump fuel feeding, and adopts two smart filter structures to filter, and makes the control system complex structure, and cost is high.
The model utility content
The purpose of the utility model is exactly to solve the problems referred to above that exist in the existing technology, and it is low to provide a kind of turbidity test to hydraulic oil to require, and reliability is high, the control system of hydro viscous variable speed drive simple in structure.
For realizing above-mentioned purpose, the technical solution of the utility model is: a kind of control system of hydro viscous variable speed drive, and it comprises motor, frequency variator, three screw pump, board-like throttle valve and valve seat; Frequency variator connects the control end of motor; Three screw pump is connected on the output shaft of motor, on the filler opening of the oil inlet pipe of three screw pump oil purifier is installed, and oil outlet tube connects the filler opening of valve seat; The oil outlet of valve seat connects the control oil pipe of hydro viscous variable speed drive main frame and each control instrument of main frame respectively, and its return opening connects fuel tank, and board-like throttle valve is installed between the filler opening of valve seat and the return opening.
Described fuel tank is the main frame fuel tank, and the oil inlet pipe of three screw pump, three screw pump and oil purifier are positioned at the main frame fuel tank, and motor, three screw pump and valve seat are separately fixed on the host computer control cover plate.
The utility model is through frequency variator adjustment motor speed; Change the input speed of three screw pump; Thereby change the fuel supply flow rate of three screw pump, reach the size of control system control input main frame hydraulic oil oil pressure, realize the purpose of hydro viscous variable speed drive speed governing.The valve seat of the utility model is difficult for stopping up, and low to the turbidity test requirement of hydraulic oil, reliability is high, and is simple in structure, stable and reliable operation, and cost is low.
