Description

Technical Field

[0001] The invention relates to the technical field of alarm devices, in particular to an alarm device for over-leakage outside the stuffing box of a high-pressure plunger pump. Background Art

[0002] The water injection pressure of the high-pressure plunger pump relies on on-site staff to inspect it every two hours. During operation, when the plunger pump leaks, the increase in packing leakage cannot be detected through monitoring video and DCS.

[0003] During the period of manual inspection, the packing leakage increased, causing the plunger pump to be forced to shut down more than 120 times per year. Since the leakage was not discovered in time, the medium entered the power end lubricating oil tank, causing the lubricating oil to deteriorate, resulting in wear of the power end crosshead and slideway, which is prone to production safety accidents.

[0004] Therefore, it is necessary to develop an excessive warning device for the leakage outside the range of the stuffing box of a high-pressure plunger pump to solve the above problems. Summary of the invention

[0005] The present invention provides a high-pressure plunger pump stuffing box leakage excess warning device, which overcomes the shortcomings of the above-mentioned prior art and can effectively solve the problem of oil deterioration caused by untimely inspection, packing leakage, and water entering the oil tank.

[0006] The technical solution of the present invention is achieved by the following measures: a high-pressure plunger pump stuffing box leakage out-of-domain excess warning device, including an out-of-domain integrated device, a liquid level measurement and control device, a detection probe, a liquid level transmitter and an audible and visual alarm; The off-domain integrated device includes a box body, a filter screen is arranged on the top of the box body, a water storage container is arranged inside the box body, a detection probe is installed in the water storage container, and the detection probe is electrically connected to the liquid level transmitter; The liquid level measurement and control device comprises a signal input terminal and a signal output terminal. The signal input terminal of the liquid level measurement and control device is electrically connected to the liquid level transmitter, and the output terminal of the liquid level measurement and control device is electrically connected to the sound and light alarm.

[0007] The following are further optimizations and / or improvements to the above technical solutions: A fixed bracket may be provided on the above-mentioned off-domain integrated device.

[0008] The filter net may include a first filter net and a second filter net.

[0009] A sewage outlet may be provided at the bottom of the above-mentioned off-site integrated device, and a valve may be installed at the sewage outlet.

[0011] The above-mentioned liquid level measurement and control device can be an intelligent dual liquid level measurement and control device.

[0012] Handrails and universal wheels are also provided.

[0013] The present invention is suitable for detecting the amount of packing leakage of a plunger pump, which reduces the labor intensity of on-site employees, provides optimization conditions for the on-site personnel management platform, reduces the frequency of abnormal replacement of lubricating oil, and reduces operating costs. After the implementation of the present invention, when the packing of the plunger pump is leaking, a remote alarm can be issued to promptly discover the problem and deal with it in a timely manner. At the same time, the excessive packing leakage can be solved, and production accidents caused by wear of the power end crosshead and slideway caused by lubricating oil deterioration can be eliminated. Safety hazards caused by long-term unmanned inspections and untimely discovery of packing leakage can be avoided. After field experiments, the present invention can effectively and quickly detect liquid level changes, with good sensitivity and remote transmission effects. Excessive packing leakage can be discovered in time, reducing the failure downtime rate of the plunger pump and avoiding the occurrence of production accidents. At the same time, the operation of the plunger pump can be efficiently detected, and the manual inspection cycle can be extended. BRIEF DESCRIPTION OF THE DRAWINGS
