Abstract

The utility model discloses an energy-saving device of a hydraulic piston pump of a filter press. A large displacement pump and a small displacement pump of a double pump with a certain ratio both pass through a pressure sensor and a control module to be connected to a reversing valve respectively through a long-diameter overflow valve and a short-diameter overflow valve, and the reversing valve is connected with a hydraulic cylinder. According to the energy-saving device of the hydraulic piston pump of the filter press, in a lower pressure area, the large displacement pump and the small displacement pump of the double pump with the certain ratio are utilized for supplying oil in a large displacement mode; in a high pressure area, the small displacement pump of the double pump with the certain ratio is utilized independently for supplying the oil; and in a constant pressure area, neither the large displacement pump nor the small displacement pump of the double pump with the certain ratio is loaded, and operation without overflow is achieved. Therefore, the load of a motor in the high pressure area is enabled to be close to the load of the motor in the low pressure area so that efficiency is improved, the temperature of the oil is lowered, and valuable energy is saved almost by half.

Description

A kind of energy saving device of pressure filter hydraulic planger pump
Technical field
The utility model relates to a kind of pressure filter hydraulic planger pump, refers in particular to a kind of energy saving device of pressure filter hydraulic planger pump.
Background technique
At present, both at home and abroad the hydraulic system of pressure filter hydraulic planger pump by an oil hydraulic pump by relief valve and selector valve to the oil hydraulic cylinder fuel feeding.Because of pressure filter hydraulic planger pump operating mode more special, large discharge capacity supply time is shorter during low pressure area, increase along with pressure filter charging resistance, the cylinder pressure of pressure filter hydraulic planger pump rises, fuel delivery descends, motor load rises, when pressure rise arrives the setting value of relief valve, because the hydraulic pressure pump delivery is always constant, just causes a large amount of hydraulic oil to overflow to fuel tank from relief valve, make motor in the always heavy duty to the zone of high pressure of middle nip, areas of permanent pressure particularly, so inefficiency, oil temperature is high, has wasted the valuable energy.
Summary of the invention
The purpose of this utility model is to solve the energy waste problem of existing pressure filter hydraulic planger pump, and a kind of energy saving device of pressure filter hydraulic planger pump is provided.The large discharge capacity fuel feeding of double pump when this device is realized low pressure area by the ratio duplex pump, the independent fuel feeding of small displacement pump during the zone of high pressure, double pump is unloaded during areas of permanent pressure, realization moves without overflow, motor is approached in the load of zone of high pressure and the load of low pressure area, therefore improve efficient, reduced oil temperature, saved nearly one times valuable energy.
For achieving the above object, the solution that the utility model is taked is: a kind of energy saving device of pressure filter hydraulic planger pump, large discharge pump and small displacement pump by the ratio duplex pump pass through respectively a large drift diameter over-flow valve and little drift diameter over-flow valve, jointly be connected to a selector valve through pressure transducer and control module, selector valve connecting fluid cylinder pressure.
When the pressure filter hydraulic planger pump when low pressure area is worked, the ratio duplex pump is fuel feeding simultaneously, reaches maximum pump discharge; When pressure transducer detects working pressure and reaches the pressure set points of control module, to control large drift diameter over-flow valve and make the large discharge pump on the ratio duplex pump unloaded, the small displacement pump continues fuel feeding, until the zone of high pressure; When pressure transducer detects working pressure and reaches the high pressure setting value of control module, control little drift diameter over-flow valve and make the small displacement pump unloaded, enter areas of permanent pressure, load and the low pressure area of motor are approached, reduce oil temperature, improved efficient, saved nearly one times valuable energy.
Description of drawings
Fig. 1 is the present embodiment structural representation.
Among the figure: 1, fuel tank, 2, the ratio duplex pump, 3, the small displacement pump, 4, large discharge pump, 5, little drift diameter over-flow valve, 6, large drift diameter over-flow valve, 7, pressure transducer, 8, control module, 9, selector valve, 10, oil hydraulic cylinder.
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Referring to Fig. 1, a kind of energy saving device of pressure filter hydraulic planger pump, the large discharge pump 4 of ratio duplex pump 2 and small displacement pump 3 are respectively by a large drift diameter over-flow valve 6 and little drift diameter over-flow valve 5, jointly be connected to a selector valve 9 through pressure transducer 7 and control module 8, selector valve 9 connecting fluid cylinder pressures 10.
