Description

The horizontal automatic pressure test device of heat collector runner
Technical field
The present invention relates to a kind of pressure testing machine for whether there is leakage to check to pipeline, more particularly, relate to a kind of automatic pressure test device for whether there is leakage to check to horizontal heat collector runner.
Background technology
Heat collector runner is the vitals of flat-plate solar collector, and heat collector runner and absorber plate form the collector plate core of flat-plate solar collector.Heat collector runner is to consist of with some combs that weld mutually with collector collector, the heat collector runner being welded by collector and some combs need to check, determine without holding plate with suction again after leaking and be assembled into collector plate core, thereby the quality of flat-plate solar collector is effectively guaranteed.Otherwise, if leak the quality of flat-plate solar collector is had a greatly reduced quality because heat collector runner exists, even cannot use, be unfavorable for improving the product percent of pass of flat-plate solar collector, also to user, brought huge loss.
At present, in sun power industry, the pressure testing of heat collector runner adopts manual type in the majority, and small part adopts pressure testing equipment.Artificial pressure testing exists that labour intensity is large, workman's fatiguability, cost of labor are high, pressure test pressure and dwell time all can not guarantee for a long time, and security incident and product quality accident easily occur, and this kind of mode belongs to superseded ranks already.All drawbacks in view of artificial pressure testing, Some Enterprises has been manufactured experimently pressure testing equipment, but this kind equipment is because design time has problems, and causes reliability extreme difference, so even sun power industry has developed into industry in large scale, but this kind equipment does not still obtain extensively and promotes.For the horizontal pressure testing equipment of heat collector runner, mainly there is following defect in tradition:
1, there is " water hammer " problem in traditional equipment for the pressure testing of horizontal heat collector runner, easily pipeline and the pipe fitting of the equipment of horizontal heat collector runner pressure testing caused to damage, has a strong impact on the serviceable life of equipment.
2, traditional equipment for the pressure testing of horizontal heat collector runner can only be by pressure piping to water filling in heat collector runner, water injection time is long, working time and the wearing and tearing of booster water pump have greatly been increased, and causing the needed time of pressure testing long, the work effect of equipment pressure testing is low, and the flow flowing into heat collector runner from pressure piping is little, in the injecting process, from flowing into the water of heat collector runner discharge, can not present full packages outflow, thereby be difficult to the Bas Discharged of heat collector runner, have the problem of choking with resentment.
If 3, find to leak at water filling, supercharging, packing stage, can not carry out in time pressure release, interrupt pressure testing process, extended operation hours, the work effect of equipment pressure testing is low.
4, traditional equipment for the pressure testing of horizontal heat collector runner is not smooth at water filling graduated discharge, in heat collector runner, there is the problem of choking with resentment, in the situation that the water discharging valve on outlet pipeline is closed, can not injected water on the position of choking with resentment due to the generation of the problem of choking with resentment in heat collector runner, and water filling pressure testing is carried out in the position that cannot choke with resentment to this generation, the position that some these generations are choked with resentment exists leaks and cannot be examined out, greatly reduces the reliability of pressure test leak-detecting.
5, traditional equipment for the pressure testing of horizontal heat collector runner cannot be discharged the water in heat collector runner rapidly in the pressure release stage, can not be emptied completely by the interior water of heat collector runner, thereby in heat collector runner, have residual water, be not easy to subsequent handling and carry out assembling product.
