Abstract
The utility model discloses a monitoring system for a high-low pressure pump of a high-low pressure thin oil station. The monitoring system comprises two low-pressure pump control loops and two high-pressure pump control loops. The two low-pressure pump control loops and the two high-pressure pump control loops are respectively connected with an intelligent power distribution meter which is connected with a main control room. The system can monitor detail states of the high-low pressure pump of the high-low pressure thin oil station so that the main control room can get operation states of the thin oil station in detail, is also applied to movable and static bearing lubricating systems in equipment of metallurgy, mine, cement and machinery, ensures normal operation of the equipment, and prolongs service life.
Description
Technical field
The utility model relates to a kind of high low pressure Lubricating-oil Station high-low pump supervisory system.
Background technique
GDZ63 high low pressure Lubricating-oil Station is mainly used in coal pulverizer bearing lubrication, according to the lubricated work principle design of dynamic and hydrostatic bearing.Be comprised of two low pressure pumps and two high pressure pump systems, main frame provides lubricated by low pressure pump when normal operation, and high-pressure service pump is when only being used in host-initiated and stopping.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, a kind of high low pressure Lubricating-oil Station high-low pump supervisory system being provided.
For achieving the above object, the utility model adopts following technical proposals:
A kind of high low pressure Lubricating-oil Station high-low pump supervisory system, it comprises two-way low pressure pump control loop and two-way high-pressure service pump control loop, links to each other with the intelligent power distribution instrument respectively on two-way low pressure pump control loop and two-way high-pressure service pump control loop.
Described intelligent power distribution instrument links to each other with two-way high-pressure service pump control loop with two-way low pressure pump control loop by current transformer.
Described intelligent power distribution instrument also links to each other with master-control room.
The utility model can be monitored the detailed status of the high-low pump of high low pressure Lubricating-oil Station, makes master-control room can understand in detail the running state of Lubricating-oil Station.Native system also is applicable in the sound bearing lubrication system in the equipment such as metallurgy, mine, cement machinery.The normal operation of assurance equipment increases the service life.

Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
For GDZ63 high low pressure Lubricating-oil Station, a kind of high low pressure Lubricating-oil Station high-low pump supervisory system is proposed, as shown in Figure 1, it comprises two-way low pressure pump control loop and two-way high-pressure service pump control loop, and the low pressure pump control loop comprises 1# low pressure pump M1 or 2# low pressure pump M2, circuit breaker Q F1 or QF2 and operation contactor KM1 or KM2.The high-pressure service pump control loop comprises 1# high-pressure service pump M3 or 2# high-pressure service pump M4, circuit breaker Q F3 or QF4 and operation contactor KM3 or KM4.
Take out three phase circuit at each road low pressure pump control loop and two-way high-pressure service pump control loop difference Current Transformer, Current Transformer TA11, TA12, TA13 take out the major loop three phase circuit in low pressure pump M1 control loop, among the current signal access intelligent power distribution instrument RA1-RA4, on the display screen of intelligent power distribution instrument RA1-RA4, can demonstrate the actual value of current electric current, this value can also 4-20mA signal import master-control room IC into, can realize that master-control room IC is to the control of field condition.Fig. 2-5 is intelligent power distribution instrument RA1-RA4 circuit theory diagrams, this figure only with electric current as signal.
What original contactor transmitted only can pass to the connecting and disconnecting state of master-control room oil pump without source contact, existing being installed on regard to the i2 Series Intelligent distribution instrument in the cabinet of increasing then can be monitored the electric current of high-low pump, voltage, power, power factor, frequency, electric energy etc., LED display by high brightness in regard to cabinet is observed, externally can carry out communication with master-control room, adopt the MODBUD-RTU communication protocol, the serial communication interface RS485 mode of connection also can provide 4～20mA analog output in addition.
Although above-mentionedly by reference to the accompanying drawings embodiment of the present utility model is described; but be not the restriction to the utility model protection domain; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
