Abstract

The invention provides a plunger pump device. The plunger pump device comprises a plunger pump, a pump bin and an alarm assembly. The plunger pump is arranged in the pump bin. The alarm assembly comprises an alarm, a power supply, a wire and two metal sheets, the power supply is connected with the alarm through the wire, and the two metal sheets are arranged on the wire at intervals. The two spaced metal sheets are arranged in the pump bin of the plunger pump. According to the technical scheme, the problem in the prior art that the plunger pump is damaged due to the fact that water leakage ofthe plunger pump is not found in time is effectively solved.

Description

technical field [0001] The present invention relates to the technical field of plunger pumps, in particular to a plunger pump device. Background technique [0002] The maintenance of high-pressure plunger pumps is large, and the pump needs to be stopped for maintenance after running for a period of time. The packing is the plunger seal of the plunger pump, which is an important accessory of the plunger pump. The service life of the packing is related to the water quality, generally within 15 days To be replaced. Whether the high-pressure plunger pump leaks in the prior art depends on the inspection by employees, and there are great unsafe factors. For example, if the packing is damaged and the plunger is not found to leak in time, the water droplets will fly over the water deflector and fall on the tappet at the power end. , Bring water droplets into the oil tank of the power end, resulting in damage to the crankshaft, sealing part, and lubricating part of the power end, an...
