Abstract
The utility model relates to a liquid pump, in particular to an electric lubricant pump. The electric lubricant pump comprises a pump body and a drive device connected with an input end of the pump body. The drive device is a variable frequency motor. The lubricant pump further comprises a control system connected with a control end of the variable frequency motor. Compared with the prior art, the variable frequency motor is adopted by the input end of the pump body to serve as the drive device and more speeds are obtained through the adjustment of the rotating speed of the variable frequency motor, so that more different output flows are obtained, the flow range of the pumps of this type is expanded, and the different requirements of users are satisfied. A gear reduction motor is not used any more, the relative cheap variable frequency motor is used and the rotating speed of the variable frequency motor is adjusted through the control of the control system, so that the pump body is driven by one motor to achieve three different kinds of flow output and the manufacturing cost is reduced.
Description
Technical field
The utility model relates to a kind of liquor pump, particularly a kind of electronic lubricating pump.
Background technique
At present, the DRB type electronic lubricating pump of standard has three kinds of different output flows on the market, is respectively 120 ml/min, 235 ml/min, 365 ml/min.In order to obtain this three kinds of different flows, need adopt the reducing motor of three different speed ratios to drive pump element and move.Can't realize adopting a motor to drive the pump housing and realize three kinds of different flows.
The model utility content
The utility model has designed a kind of electronic lubricating pump in order to overcome the deficiencies in the prior art, can't adopt a motor to drive three kinds of different flows outputs of pump housing realization to overcome.
To achieve these goals, the utility model provides a kind of electronic lubricating pump, comprises the pump housing, and with the drive unit that pump housing input end is connected, described drive unit is variable-frequency motor; Described lubricant pump also comprises the control system that is connected with described variable-frequency motor control end.
Mode of execution of the present utility model is compared with prior art, because the input end employing variable-frequency motor conduct at the pump housing is drive unit, utilize the rotational speed regulation of variable-frequency motor to obtain more speed, and then the more same output flows not of acquisition, expand the range of flow of such pump, thereby satisfied user's different needs.Because present embodiment does not re-use toothed gearing electric motor, but use relatively cheap variable-frequency motor, and regulate the variable-frequency motor rotating speed by the control of control system, not only realize adopting a motor to drive the pump housing and realize three kinds of different flows outputs, and reduced the cost of making.
Preferably, described control system comprises a remote computer.The user can regulate by remote computer the rotating speed of variable-frequency motor.
Preferably, described control system also comprises the speed governing panel, and described speed governing panel is integrated on the described variable-frequency motor, or is connected with the control end of variable-frequency motor.The user also can directly regulate the rotating speed of variable-frequency motor by the speed governing panel.And change the flow output in the pump housing when speed governing panel can be according to various Demand; The scope that has limited the frequency transfer can overload burning with the protection motor.
Preferably, be provided with on the described speed governing panel that this locality is controlled and remote-operated diverter switch be used to being provided with.Only beat on long-range in diverter switch, computer just can long-rangely carry out the speed governing operation, avoids simultaneously variable-frequency motor being operated at local and remote end, causes the generation of misoperation.

Fig. 2 is the lubricated use schematic block diagram of the utility model the first mode of execution single line;
Referring to Fig. 1,1 is the pump housing; 2 is variable-frequency motor; 3 is remote computer; 4 are the speed governing panel.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with accompanying drawing the embodiments of the present invention are explained in detail.Yet, persons of ordinary skill in the art may appreciate that in each mode of execution of the present invention, in order to make the reader understand the application better many ins and outs have been proposed.But, even without these ins and outs with based on many variations and the modification of following each mode of execution, also can realize each claim of the application technological scheme required for protection.
The first mode of execution of the present utility model relates to a kind of electronic lubricating pump, and as shown in Figure 1: comprise the pump housing 1, with the drive unit that pump housing input end is connected, described drive unit is variable-frequency motor 2; Described lubricant pump also comprises the control system that is connected with described variable-frequency motor control end.Control system is a remote computer 3.
In the present embodiment, because the input end at the pump housing 1 adopts variable-frequency motor 2 as being drive unit, utilizes the rotational speed regulation of variable-frequency motor 2 to obtain more speed, and then obtains how different output flows, expand the range of flow of such pump, thereby satisfied user's different demands.Owing to not re-using toothed gearing electric motor, but use relatively cheap variable-frequency motor, and regulate the variable-frequency motor rotating speed by the control of control system, not only realize adopting a motor to drive the pump housing and realize three kinds of different flows outputs, and reduced the cost of making.
And in the present embodiment, remote computer 3 can operate a plurality of pump housings simultaneously, only the variable-frequency motor in a plurality of pump housings need be connected on same the remote computer to get final product.Give each variable-frequency motor a frequency values, can feed back and obtain a rotating speed/flow value, can accurately control the flow of each pump, and remote computer can gather pump housing internal pressure value by variable-frequency motor, guarantee that each pump housing works well.
The second mode of execution of the present utility model relates to a kind of electronic lubricating pump.The second mode of execution has been done further improvement at the first mode of execution, and main improvements are: control system also comprises speed governing panel 4, and speed governing panel 4 can be integrated on the described variable-frequency motor 2, or is connected with the control end of variable-frequency motor 2.The user also can directly regulate the rotating speed of variable-frequency motor 2 by speed governing panel 4.And change the flow output in the pump housing 1 when speed governing panel 4 can be according to various Demand, having limited the scope that frequency transfers can overload burning with the protection motor.
In addition in the present embodiment, be provided with on the speed governing panel 4 that this locality is controlled and remote-operated diverter switch be used to being provided with.Only beat on long-range in diverter switch, remote computer 3 just can long-rangely carry out the speed governing operation, avoids simultaneously variable-frequency motor 2 being operated at local and remote end, causes the generation of misoperation.
Persons of ordinary skill in the art may appreciate that the respective embodiments described above are to realize specific embodiment of the utility model, and in actual applications, can do various changes to it in the form and details, and do not depart from spirit and scope of the present utility model.
