Abstract

The utility model relates to a device for automatically reminding lubrication and recording refueling times, which belongs to the field of gas metering devices. The device comprises a flow totalizer,a flowmeter base table, a refueling component, a refueling sensor, a shell, a movement component and a flow sensor, and a bearing and a rotary sensing piece synchronously rotate along an impeller; therefueling sensor is connected with the movement component; and a buoy sensing piece vertically moving along with the rising and the descending of lubricating oil is arranged in an oil storage cup ofthe refueling component. The device is carried out according to the principle that the medium flow detected through the flow sensor is in proportion to the number of revolution of the bearing; the device solves the difficult problems of automatic reminding of bearing refueling in the gas flowmeter and automatic recording to the refueling times, protects the bearing in time, prolongs the service life of the bearing, and effectively avoids the metering error of the flowmeter due to the bearing problem; moreover, the device is suitable for gas turbines and Roots flowmeters.

Description

Automatically remind device oily and record oiling number of times

Technical field

The utility model relates to gas dosing instrument field, is a kind ofly to remind oily and record to refuel the device of number of times automatically to the rolling bearing in the gas meter (turbine and Roots).

Background technology

Rolling bearing is a most important tumbler in gas turbine meter and the gas Roots type flowmeter, the flow size of its number of revolutions and flowmeter is directly proportional, when rolling bearing (the rolling bearing number of revolutions is few in the unit interval) when operation under low discharge for a long time, if take the set time to refuel, bearing can be because lubricating oil too much rotates slow partially; When (the rolling bearing number of revolutions is many unit interval in) operation is and untimely when oily under big flow for a long time, bearing can cause damage because generate heat; Therefore whether its normal operation measuring accuracy that whether is directly connected to flowmeter can reach the requirement of appointment.At present, though two kinds of flowmeters of gas-turbine both domestic and external and Roots have adopted manually operated refueling device to rolling bearing oily, but the number of times that refuels is all undertaken by the set time requirement, refuel once such as two months or three months, almost do not consider of the influence of the actual flow size of flowmeter the rolling bearing rotation; On the other hand, whether refuel, do not have concrete oiling record, whether refuel by the set time requirement, the textual criticism of having no way of, this is unscientific.

Summary of the invention

For overcoming above-mentioned deficiency, the device that provides the oily and record of a kind of automatic prompting to refuel number of times to this area is provided, the fundamental relation that utilizes the size of gas turbine meter and Roots type flowmeter medium flow to be directly proportional with the number of revolutions of rolling bearing, thereby when the number of revolutions of bearing reaches the number of revolutions of setting, will remind automatically and refuel and to refueling the device that number of times writes down, it is to realize by following technical scheme.

Oily and the record of a kind of automatic prompting refuels the device of number of times, this device comprises flow integrator, flowmeter base table, refuel assembly, add oil sensor, flowmeter shell, watch core assembly, flow sensor, rolling bearing and rotary inductive sheet rotate synchronously with impeller; Adding oil sensor is connected with the oiling assembly; The assembly that refuels is made up of oil storage cup, button, retaining valve and oil inlet pipe, is provided with the buoy sensing chip that the lifting with lubricating oil moves up and down in the oil storage cup.

The utility model is to implement with the principle that the number of revolutions of bearing is directly proportional according to the size that flow sensor detects rate-of flow: the number of revolutions that converts bearing after promptly the detected rate-of flow of flow sensor is handled by flow integrator to, when the number of revolutions of bearing reaches the setting number of revolutions that needs oiling (its number of revolutions that need refuel of different bearings is different), on the LCDs of flow integrator, will demonstrate the information that needs oiling, remind the user in time to refuel; In the process of refueling, the buoy sensing chip in the oil storage cup can move up and down along with the lifting of lubricating oil, at this moment adds oil sensor and can sense the signal that the buoy sensing chip moves up and down; When the oiling sensor sensing arrives this signal, show bearing is refueled; When adding oil sensor and not sensing this signal, do not illustrate bearing is refueled, so just reach to remind and refuel and refueling the purpose that number of times writes down.Simultaneously, remind the signal of oiling and oiling number of times to export by teletransmission.

The utility model has solved in the gas meter how the oiling of rolling bearing is reminded automatically and has carried out a self registering difficult problem to refueling number of times; the timely serviceable life of protecting bearing and having prolonged bearing; avoid the flowmeter error in dipping that causes because of bearing problem effectively, be applicable to gas-turbine and Roots type flowmeter.

Fig. 2 is refueling device and the cross sectional representation that adds oil sensor;

Fig. 3 is the principle schematic of flow integrator.

Embodiment

Now, principle of work of the present utility model is described as follows in conjunction with Fig. 1.As shown in Figure 1, when reminding the device busy state of oily and record oiling number of times automatically, gas flows into from housing 3 one ends of flowmeter base table 13, the other end flows out, impeller 14 in the watch core assembly 10 drives bearing 11 and rotary inductive sheet 4 rotates synchronously, be installed on flow sensor 2 in the flowmeter shell according to the size detection of gas flow number of revolutions to the rotary inductive sheet, because bearing and rotary inductive sheet are rotations synchronously, so the number of revolutions of rotary inductive sheet also is the number of revolutions of bearing, this number of revolutions is handled through flow integrator 1 and when reaching the setting number of revolutions that needs to refuel, and promptly showing on the LCDs of flow integrator needs the alerting signal 16 that refuels.This moment, shown in Fig. 2～3, add lubricating oil to the position that requires in the oil storage cup 6 of assembly 12 refueling, buoy sensing chip 7 floats along with the rising of lubricating oil, when when adding oil sensor 5, add oil sensor and just receive the fueling signal 19 that an expression oil is rising; Repeatedly push the button 8 in the oiling assembly then, make lubricating oil from oil storage cup, begin to descend and enter oil inlet pipe 9 to arrive bearings, can be lubricated bearing by retaining valve 15; When lubricating oil began to descend from oil storage cup, buoy sensing chip 7 also can be along with decline, receives the fueling signal 19 that an expression oil is descending when adding oil sensor again; When adding oil sensor and receive these two fueling signals, represent that a refueling process finishes, flow integrator this moment refueling process of record and eliminate original oiling alerting signal 16 that occurs automatically.When appearance for the second time needs the alerting signal 16 that refuels and receives two fueling signals 19 of refueling process, flow integrator can write down storage equally automatically, reached automatic prompting oiling and the oiling number of times has been carried out automatic record, and and flow signal 18 be reflected in together on the LCD display 17, make it very clear.
