Technical Field

The utility model relates to a take liquid level to detect grease pump oil storage section of thick bamboo of function in succession.

Background

At present, the mainstream dry oil electric lubricating pump is a pump device below, an oil storage cylinder is in an upper structure, and the lubricating pump can work after a proper amount of lubricating grease is supplemented into the oil storage cylinder. At present, more and more enterprises advance intelligent manufacturing, the operation condition of field equipment can be monitored in a main control room, the liquid level of an oil storage cylinder is used as an important technical index of a dry oil electric lubricating pump and must be fed back truly and reliably, automatic grease supplement can be carried out on the oil storage cylinder through the oil storage cylinder, the liquid level reaches a set low-level control grease supplement device to supplement grease to the oil storage cylinder, and the liquid level reaches a set high-level automatic stop grease supplement, the amount of grease supplied to the outside of the lubricating pump is monitored in real time, and automatic alarm can be carried out if the amount of the grease supplied in a certain time is obviously larger than a normal value. Because the grease is sticky and has almost no fluidity, some liquid level detection means for fluid are not suitable for the grease, and the current common mode adopts an ultrasonic liquid level sensor for detection, but has some defects: the price of the sensor is high; the liquid level in the oil storage cylinder is uneven and sometimes presents a funnel shape with high periphery and low middle, so that the liquid level detected by the sensor has deviation with the actual state; the diameter of the dry oil storage cylinder is small and is a closed space, and the liquid level is uneven due to a certain divergence angle generated by the ultrasonic sensor, so that the feedback signal of the sensor is easy to fluctuate due to the diffuse reflection interference of ultrasonic waves; the sensor is installed on the bung, and the inside actual liquid level of oil storage section of thick bamboo is external can not see, and the staff can't in time discover if the sensor has a fault.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a take grease pump oil storage cylinder of liquid level continuous detection function, including the oil storage barrel, the oil storage cover is established to the top surface of oil storage barrel. An integrated oil pressing disc is arranged in the oil storage cylinder, a hollow indicating rod penetrates through an oil storage cylinder cover and extends into the oil storage cylinder, then the hollow indicating rod is connected with the integrated oil pressing disc, and the indicating rod and the integrated oil pressing disc are fixed through an adjusting nut and a locking nut. The indicating rod is hermetically connected with the oil storage cylinder cover through a felt; and a contact is arranged on the upper part of the indicating rod, which is positioned on the outer side of the oil storage cylinder cover, and the contact is fixed on the indicating rod through a set screw. An exhaust cavity is arranged in the contact, an exhaust valve is arranged on the side surface of the contact, and the exhaust valve is communicated with the indicating rod through the exhaust cavity; the upper end surface of the oil storage cylinder cover is fixedly provided with a linear displacement sensor for liquid level detection through a bracket, and a sliding block of the linear displacement sensor is connected with a connecting rod fixed on a contact through a connecting piece; the connecting piece is fixed on the connecting rod through a nut. The transparent protective cover covers the contact and the linear displacement sensor on the upper end surface of the oil storage cylinder cover.

Detailed Description

As shown in figure 1, the grease pump grease storage cylinder with the continuous liquid level detection function comprises a grease storage cylinder body 1, and a grease storage cylinder cover 6 is arranged on the top surface of the grease storage cylinder body 1. An integrated oil pressing disc 2 is arranged in the oil storage cylinder body 1, and the lower part of the integrated oil pressing disc 2 is in contact with lubricating grease and moves up and down along with the liquid level of the lubricating grease. The integrated oil pressing disc 2 is a steel part with the self weight of 10-20 kg, and the liquid level of the grease surface is guaranteed. The oil blanket 18 of the integrated L type of integral type pressure dish 2 excircle, oil blanket 18 and the formation of oil storage barrel 1 inner wall are sealed, prevent that lubricating grease from overflowing to integral type pressure dish 2 top at the in-process that integral type pressure dish 2 removed. The indication rod 3 penetrates through the oil storage cylinder cover 6 to extend into the oil storage cylinder body 1 and then is connected with the integrated oil pressing disc 2, and the indication rod 3 and a central through hole 19 of the oil storage cylinder cover 6 are sealed by a felt seal 16 to form a seal. The indication rod 3 and the integrated oil pressing disc 2 are fixed through the adjusting nut 4 and the locking nut 5, and move up and down along with the integrated oil pressing disc 2, and the position of grease in the barrel can be generally known by visually observing the extending height of the indication rod 3. A contact 13 is mounted on the top of the indication rod 3, which is positioned on the outer side of the oil storage cylinder cover 6, and the contact 13 is fixed by a set screw 15. The top of the contact 13 is fixedly provided with a connecting rod 12, an exhaust cavity 17 is arranged in the contact 13, an exhaust valve 14 is arranged on the side surface of the contact 13, and the exhaust valve 14 is communicated with an inner hole 20 of the indicating rod 3 through the exhaust cavity 17. The indicating rod 3 is a hollow pipe, air gathered at the lower part of the integrated oil pressing disc 2 can be exhausted by opening the exhaust valve 14, the air needs to be exhausted during the first grease supplement, and the indicating rod is opened and checked regularly after the indicating rod is used normally. The linear displacement sensor 8 is fixed on the oil storage cylinder cover 6 through a bracket 7. The liquid level is detected by the linear displacement sensor 8, and the liquid level detection device is good in reliability and high in precision. The slide of the linear displacement sensor 8 is connected via a coupling piece 10 to a connecting rod 12 which is fixed to a contact 13.
