Abstract

The utility model relates to a method and a device for detecting discharge and replenishment of propulsive liquid of a piston diaphragm pump. The piston diaphragm pump is provided with a more liquid detection probe and a less liquid detection probe, wherein a detection rod is positioned in a propulsive liquid chamber, and an end part of the detection rod is also positioned between the more liquid detection probe and the less liquid detection probe; and a detection magnet is arranged outside the piston diaphragm pump and is also positioned between the more liquid detection probe and the less liquid detection probe. Since the detection magnet is arranged, whether an oil discharge or replenishment signal is available can be quickly detected so as to quickly and timely remove a fault.

Description

A kind of device that detects piston diaphragm pump row benefit PF

Technical field

The utility model relates to a kind of device that piston diaphragm pump row mends PF that detects.

Background technique

For pumping high concentration ground paste, mud or mine tailing, preferably use piston diaphragm pump.This pump is to seal from the material of piston to abrasion by a hydraulically powered barrier film, can control diaphragm position on the either direction of stroke by the PF in the cavity between filling or discharge piston and barrier film.

Specifically, be respectively corrosive material and PF in the barrier film both sides, barrier film keeps balance by being subjected to the extruding of material and PF simultaneously, thereby guarantees material and moving element such as piston, and piston rod or piston cylinder etc. are contactless.

But also can there be a defective in self this piston diaphragm pump: when long operation piston diaphragm pump, cause testing signal to lose efficacy because impurity such as dust constantly enter, this will trigger warning, will cause membrane ruptures and bring other bigger influences when serious.

Thereby if PF too much or very little the time, PF need keep the pressure system of balance destroyed, will cause the material of abrasion to enter in the moving element, has influence on the normal operation even the working life of the reciprocal positive-displacement pump of high pressure.

Summary of the invention

The utility model has designed a kind of device that piston diaphragm pump row mends PF that detects, the technical problem of its solution is when moving piston diaphragm pump for a long time, cause testing signal to lose efficacy because impurity such as dust constantly enter, will cause membrane ruptures and bring other bigger influences when serious.

In order to solve the technical problem of above-mentioned existence, the utility model has adopted following scheme:

A kind of device that detects piston diaphragm pump row benefit PF, many liquid detect probe and few liquid detect probe are set on piston diaphragm pump, test rod advances liquid chamber and its end also to be between many liquid detect probe and the few liquid detect probe being arranged in, and described detection magnet is arranged on the piston diaphragm pump outside.

The device that this detection piston diaphragm pump row mends PF has following beneficial effect:

(1) the utility model can monitor and in time replenish or the discharge PF by many liquid detect probe or few liquid detect probe piston diaphragm pump, guarantees the piston diaphragm pump safe operation.

(2) also because a detection magnet is being set, detection magnet is installed in use additional can detect fast whether row, repairing signal are arranged to the utility model, so that the quick fault of discharge in time.

Description of drawings

Fig. 1 is that the row of piston diaphragm pump PF in the utility model mends the work schematic representation.

Description of reference numerals:

1-many liquid detect probe; 2-few liquid detect probe; 3-detection magnet; 4-barrier film; 5-test rod.

Embodiment

Below in conjunction with Fig. 1, the utility model is described further:

A kind of device that detects piston diaphragm pump row benefit PF, many liquid detect probe 1 and few liquid detect probe 2 are set on piston diaphragm pump, test rod 5 advances liquid chamber and its end also to be between many liquid detect probe 1 and the few liquid detect probe 2 being arranged in, and detects magnet 3 and is arranged on the piston diaphragm pump outside.

This working principle that detects piston diaphragm pump row benefit PF device is as follows:

Under normal operative condition, test rod 5 motion between many liquid detect probe 1 and few liquid detect probe 2 can trigger signal;

Perhaps, if the PF in the propelling liquid chamber very little, test rod 5 triggers few liquid detect probe 2 backs and produces a pulse signal to PLC, and thus start signal output fluid infusion electromagnetism pilot valve and fluid infusion pneumatic valve a period of time, PF will be added in the propelling liquid chamber;

Perhaps, if advance in the liquid chamber PF too many, test rod triggers many liquid detect probe 1, and produces a pulse signal to PLC, start signal output discharge opeing electromagnetism pilot valve and after discharge opeing pneumatic valve a period of time thus, and PF is just from advancing the liquid chamber discharge;

Perhaps, advance in the liquid chamber PF too much or very little and can not effectively discharge or when additional, advance liquid chamber to produce one and need or lack the alarm signal that liquid detect probe 2 is checked many liquid detect probe 1, many liquid detect probe 1 or few liquid detect probe 2 are taken out, perpendicular alignmnet detects magnet 3, slowly move from top to bottom, and check whether row's repairing signal is arranged; If row's repairing signal is arranged, remove many liquid detect probe 1 or few liquid detect probe 2 more gradually, check whether signal disappears; If disappear, that will carry out the impurity cleaning to many liquid detect probe 1 or few liquid detect probe 2 riding positions; If do not arrange the repairing signal, that just needs to change many liquid detect probe 1 or few liquid detect probe 2.

In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obvious realization of the present utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technological scheme to carry out; or design of the present utility model and technological scheme are directly applied to other occasion without improving, all in protection domain of the present utility model.
