Abstract
The utility model relates to a system for carrying out vacuum leak detection on large vacuum chambers in batches, which comprises a vacuum leak detection instrument, the vacuum leak detection instrument is connected with a vacuum roughing pump, both the vacuum leak detection instrument and the vacuum roughing pump are connected with a vacuum meter which is used for acquiring dynamic vacuum degree data when the vacuum system carries out rough vacuumization, and the other side of the vacuum meter is connected with detected products. The utility model has the following advantages: (1) the system can simultaneously roughly vacuumize a plurality of products and detect the leak rate of large vacuum products in batches, thus greatly shortening the detection time; and when an abnormal leak rate occurs, the products connected with the system can be controlled by valves in order to be identified one by one; (2) the vacuum meter is utilized to acquire the dynamic vacuum degree data of the system; (3) because the system first roughly vaccumizes the products, the air in the products is relatively purified, consequently, the air can achieve the cleanliness required by the high-precision leak detection instrument, and the leak detection instrument can be kept in a sensitive state; and the service life of the leak detection instrument is prolonged.
Description
Technical field
The vacuum leak rate that the utility model relates to a kind of vacuum product detects.
Background technology
Generally the vacuum product being carried out the inspection of vacuum leak rate, all is to adopt vacuum leak detector directly to be connected with product to check, as Fig. 1.There is following shortcoming in this kind method:
1, generally all smaller, bigger to the cavity volume vacuum product of power of the subsidiary roughing vacuum pump of leak locator vacuum system vacuumizes the test vacuum degree condition that reaches regulation, and is consuming time long;
2, the bigger product of cavity volume is carried out vacuum leak hunting, leak locator can be because of the operation of high load capacity for a long time, to very big influence is arranged in serviceable life of leak locator;
3, bulky vacuum product cavity, when not having specialized equipment integral body to clean, the artificial inner chamber of cleaning does not reach the cleanliness factor that the high precision leak locator requires usually, vacuumizes in this state, and the leak locator parts are fragile, particularly the molecular pump in the system;
4, leak locator generally uses under the environment in headroom room, and when environment did not reach the cleanliness factor requirement, the precise decreasing of leak locator was than very fast.
Summary of the invention
The utility model will solve existing vacuum leak hunting method and have problem time-consuming, that the inspection precision is low, the leak locator life-span is short, and the system that is used for vacuum leak detection of large vacuum chambers in batches that a kind of detection time is short, precision is high, the leak locator life-span prolongs is provided.
The technical solution of the utility model:
A kind of system that is used for vacuum leak detection of large vacuum chambers in batches, comprise vacuum leak detector, it is characterized in that: described vacuum leak detector also is connected to the vacuum roughing vacuum pump, the vacuum holder table of the vacuum tightness dynamic data when described vacuum leak detector and described roughing vacuum pump all are connected and are used to obtain vacuum system and slightly take out, the opposite side of described vacuum holder table is connected with testing product.
Further, be connected with a plurality of inspection products on the described vacuum holder table.
Further, be equipped with vacuum valve between described vacuum holder table and inspection product, vacuum roughing vacuum pump, the vacuum leak detector.
Further, the connecting line of described vacuum holder table is provided with spare interface.
Further, be connected by weldless steel tube between described vacuum holder table and the vacuum valve.
Further, all be connected between described inspection product, vacuum roughing vacuum pump, vacuum leak detector and the vacuum valve by corrugated tube.
The utility model was slightly taken out the large-scale vacuum product with the vacuum roughing vacuum pump earlier in when leak detection, treat that vacuum tightness in the detected product reaches condition of high vacuum degree after, with high-precision leak locator detected product is carried out essence and takes out and check.
The beneficial effects of the utility model:
1, system has realized that several products slightly take out simultaneously, detects at large-scale vacuum product leak rate in batches, has shortened detection time greatly; When unusual leak rate takes place, also can control the product of connecting system, confirm one by one by valve;
2, obtain the dynamic vacuum degrees of data of system by vacuum holder table;
3, this system slightly takes out product earlier, has purified the air in the product relatively, makes its cleanliness factor that reaches the requirement of high precision leak locator, makes leak locator keep sensitive state; Prolong the serviceable life of leak locator.
