Abstract
A water flow detecting device for a dry type vacuum unit belongs to the technical field of dry type vacuum units, and comprises a glass shell, a needle valve, a nut, a floater, a water inlet and a water outlet. A conical cavity, the water inlet, the water outlet and a channel for mounting the needle valve are arranged in the glass shell, the water inlet and the water outlet are communicated with the conical cavity, a needle end of the needle valve extends into the water inlet, the needle valve is perpendicular to the conical cavity, the floater is disposed in the conical cavity, the nut is mounted at a port of the conical cavity, and a proximity switch which is connected with an alarm and used for detecting the height of the floater is mounted on the outer wall of the glass shell. The water flow detecting unit is adaptive to different vacuum environments by the aid of the needle valve which is additionally mounted on the glass shell and used for adjusting water flow, further realizes a water interruption alarm function by the aid of the proximity switch which is mounted on the glass shell and used for detecting the position of the floater, is easy in processing, detecting and maintenance, low in cost and reliable in detection, and further plays performances of the unit.
Description
Technical field
The utility model belongs to dry vacuum machine set technology field, specifically a kind of current pick-up unit that is used for dried pump vacuum unit.
Background technology
Development along with information industry, semicon industry is in the ascendant, associated industry is flourish especially, and the various device of semicon industry be unable to do without vacuum acquisition device, therefore the dry vacuum unit does not have oil because of it is clean, advantages such as maintenance period is long have good application prospects in the vacuum acquisition field of semicon industry, the pump housing cooling of dry vacuum unit is of crucial importance for the unit operate as normal, take out different vacuum atmospheres for unit, the cooling water flow difference of pump, require to have the circuit water alarm function simultaneously to being lower than certain discharge, chilled water contains impurity or equipment and water generation electro-chemical reaction produces colloid so cause the current pick-up unit to block or current not smooth, so require the current pick-up unit to be easy to care and maintenance.
The utility model content
At the technical matters of above-mentioned existence, the utility model provides a kind of current pick-up unit that is used for the dry vacuum unit, and it is based on the glass housing, in establish float, and install needle-valve additional and regulate discharge, detect float position by proximity transducer, and then realize circuit water alarm.
The technical solution adopted in the utility model is as follows:
. a kind of current pick-up unit that is used for the dry vacuum unit, it is characterized in that: comprise glass housing, needle-valve, nut, float and entery and delivery port, have conical cavity and the entery and delivery port that communicates with described conical cavity in the described glass housing, be used to install the passage of needle-valve, the pin end of needle-valve stretches into water inlet, described needle-valve is vertical with conical cavity, in conical cavity, be provided with float, nut is installed on the port of conical cavity, and the proximity transducer of the detection float height that is connected with alarm is installed on the external wall of glass shell.
Described glass housing internal fixation has guide rail, and float places on the guide rail.Have scale on the described glass housing.
The technical solution of the utility model is:
Compared with prior art, the utlity model has following beneficial effect:
1. to adopt the organic glass housing be main body to the utility model, is easy to processing, installs needle-valve additional and regulate discharge on the organic glass housing, and the adjusting by discharge is fit to different vacuum environments.Have big slope than conical cavity perpendicular to the needle-valve direction in the glass housing, in the awl conical cavity stainless steel float is set, utilize the effect of current to float, current are big more, and float moves up high more, by the scale on the glass housing, measure the size of discharge.The proximity transducer of installing on the glass housing is used to detect float position, and then realizes circuit water alarm.
2. the utility model is easy to processing, dismounting and safeguards that each parts utilize screw thread to be installed together, and is very easy to dismounting and safeguards, accomplishes that a spanner and a screwdriver just can safeguard.
The utility model overcome the big slope of glass rotameter than pipe be difficult to the blowing, process loaded down with trivial details, yield rate is low, frangible shortcoming, just can realize of the requirement of dry vacuum unit by the big slope in the glass housing than conical cavity to cooling water flow, durable, be easy to processing, cost is low, detect reliable, and then the performance of performance unit.
