Abstract

The invention discloses a method for testing pressure by the adoption of a vertical and automatic heat collector flow channel pressure test machine. The method comprises the five steps of water injection, pressure boosting, pressure maintaining, interrupting and pressure relief. The adopted vertical and automatic heat collector flow channel pressure test machine comprises a support and a control box arranged on one side of the support, the support is at least provided with one test station, and a water injection system and a pressure boosting system are arranged in the control box. In the water injection stage, the water injection system and the pressure boosting system inject water into a water collector flow channel at the same time, the working time of a pressure boosting water pump is greatly shortened, high-flow water injection is faster, it is easily ensured that water of which a water outlet pipe is full flows out of the water outlet pipe, air in the heat collector flow channel is thoroughly exhausted, the problem that air is reserved in the heat collector flow channel is eliminated, and heat collector flow channel pressure test working efficiency and pressure test leakage detection reliability can be greatly improved; a valve capable of being slowly closed is adopted on the water outlet pipe, so that water hammer is weakened or eliminated, and the service life of the vertical heat collector flow channel pressure test machine is prolonged.

Description

The method that adopts the vertical automatic pressure test device of heat collector runner to carry out pressure testing
Technical field
The present invention relates to a kind of pressure-measuring method that whether has leakage to check to pipeline, more particularly, relate to a kind of vertical automatic pressure test device pressure-measuring method that whether has leakage to check to heat collector runner.
Background technology
Heat collector runner is the vitals of flat-plate solar collector, the collector plate core of heat collector runner and absorber plate composition flat-plate solar collector.Heat collector runner is to be made up 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 the quality that makes flat-plate solar collector is had a greatly reduced quality because heat collector runner exists to leak, even cannot use, be unfavorable for improving the product percent of pass of flat-plate solar collector, also bring huge loss to user.
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 cannot ensure for a long time, and security incident and product quality accident easily occur, and this kind of mode belongs to superseded ranks already.In view of all drawbacks 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, even so sun power industry has developed into industry in large scale, but this kind equipment does not still obtain extensive popularization.Mainly there is following defect in the method that adopts the vertical pressure testing equipment of traditional heat collector runner to carry out pressure testing:
There is " water hammer " problem in the method that 1, adopts the vertical pressure testing equipment of traditional heat collector runner to carry out pressure testing, easily pipeline and the pipe fitting of the vertical pressure testing equipment to heat collector runner cause damage, have a strong impact on the serviceable life of equipment.
2, adopting the vertical pressure testing equipment of traditional heat collector runner to carry out the method for pressure testing can only be by pressure piping to water filling in heat collector runner, flow in inflow heat collector runner is little, water injection time is long, working time and the wearing and tearing of booster water pump are greatly increased, and causing the needed time of pressure testing long, the work pressure test efficiency of equipment is low.
If 3, find to leak at water filling, supercharging, packing stage, can not carry out in time pressure release, interrupt pressure testing process, extend operation hours, the inefficiency of equipment pressure testing.
4, adopting the vertical pressure testing equipment of traditional heat collector runner to carry out the method for pressure testing can only be by pressure piping to water filling in heat collector runner, flow in input heat collector runner is little, the water filling stage can not ensure that outlet pipeline full-section pipe-flow goes out current, cause exhaust not smooth, in heat collector runner, there is the problem of " choking with resentment ", water discharging valve on outlet pipeline has been 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 reduce the reliability of pressure test leak-detecting.
Summary of the invention
The object of the invention is to overcome above-mentioned defect of the prior art, provide in a kind of pressure testing process and produce without problem of water hammer, and eliminate the problem that produces " choking with resentment " and " water hammer " in heat collector runner, can significantly improve the reliability of work pressure test efficiency and pressure test leak-detecting, be convenient to subsequent handling and carry out the method that the vertical automatic pressure test device of employing heat collector runner of assembling product carries out pressure testing.
For achieving the above object, technical scheme provided by the invention is as follows:
