Description
技术领域technical field
本发明涉及一种对管道是否有泄漏进行检查的试压方法,更具体地说,是涉及一种对集热器流道是否有泄漏进行检查的立式自动试压机试压方法。The invention relates to a pressure testing method for checking whether there is leakage in a pipeline, and more specifically relates to a pressure testing method for a vertical automatic pressure testing machine for checking whether there is leakage in a flow channel of a heat collector.
背景技术Background technique
集热器流道是平板太阳能集热器的重要部件,集热器流道与吸热板组成平板太阳能集热器的集热器板芯。集热器流道是由集管和与集管相焊接的若干根排管构成,由集管和若干根排管焊接而成的集热器流道需要进行检查,确定无泄漏后再与吸执板组装成集热器板芯,从而使平板太阳能集热器的质量得到有效的保证。否则,若因集热器流道存在泄漏将使平板太阳能集热器的质量大打折扣,甚至无法使用,不利于提高平板太阳能集热器的产品合格率,也给用户带来了巨大的损失。The collector flow channel is an important part of the flat solar collector, and the collector flow channel and the heat absorbing plate form the collector plate core of the flat solar collector. The collector flow channel is composed of a header pipe and several row pipes welded with the header pipe. The collector flow channel welded by the header pipe and several row pipes needs to be inspected, and then connected with the suction pipe after confirming that there is no leakage. The executive plate is assembled into the collector plate core, so that the quality of the flat solar collector is effectively guaranteed. Otherwise, if there is leakage in the flow channel of the collector, the quality of the flat solar collector will be greatly reduced, or even unusable, which is not conducive to improving the product qualification rate of the flat solar collector, and also brings huge losses to users.
目前,在太阳能行业内,集热器流道试压采用人工方式居多,少部分采用试压设备。人工试压存在劳动强度大、工人易疲劳、人工成本高、试压压力和保压时间均无法长时间保证,易发生安全事故和产品质量事故,此种方式早已属于淘汰行列。鉴于人工试压的种种弊端,部分企业试制了试压设备,但此类设备由于设计时即存在问题,导致可靠性极差,所以即使太阳能行业已经发展成规模庞大的产业,但此类设备仍然没有获得广泛推广。采用传统集热器流道的立式试压设备进行试压的方法主要存在以下缺陷:At present, in the solar energy industry, the pressure test of the collector flow channel is mostly done manually, and a small part uses pressure test equipment. Manual pressure testing is labor-intensive, workers are prone to fatigue, labor costs are high, the pressure test pressure and pressure holding time cannot be guaranteed for a long time, and safety accidents and product quality accidents are prone to occur. This method has long been eliminated. In view of the various disadvantages of manual pressure testing, some enterprises have trial-produced pressure testing equipment, but such equipment has extremely poor reliability due to design problems. Therefore, even though the solar energy industry has developed into a large-scale industry, such equipment is still Not widely promoted. The method of pressure test using the vertical pressure test equipment of the traditional collector flow channel mainly has the following defects:
1、采用传统集热器流道的立式试压设备进行试压的方法存在“水锤”问题,容易对集热器流道的立式试压设备的管路及管件造成损坏,严重影响设备的使用寿命。1. There is a "water hammer" problem in the pressure test method using the vertical pressure test equipment of the traditional collector flow channel, which is easy to cause damage to the pipeline and pipe fittings of the vertical pressure test equipment of the collector flow channel, seriously affecting The service life of the equipment.
2、采用传统集热器流道的立式试压设备进行试压的方法只能通过增压管路向集热器流道内注水,流入集热器流道中的流量小,注水时间长,大大增加了增压水泵的工作时间和磨损,并造成试压所需要的时间长,设备的试压工作效率低。2. The pressure test method using the vertical pressure test equipment of the traditional collector flow channel can only inject water into the collector flow channel through the pressurized pipeline. The flow into the collector flow channel is small, and the water injection time is long, which greatly increases It reduces the working time and wear of the booster pump, and causes a long time for pressure testing, and the efficiency of the pressure testing of the equipment is low.
3、在注水、增压、保压阶段若发现漏水,不能及时进行泄压,中断试压过程,延长了设备运行时间,设备试压的工作效率低。3. If water leakage is found in the stages of water injection, pressurization, and pressure maintenance, the pressure cannot be released in time, the pressure test process will be interrupted, the running time of the equipment will be prolonged, and the working efficiency of the equipment pressure test will be low.
4、采用传统集热器流道的立式试压设备进行试压的方法只能通过增压管路向集热器流道内注水,输入集热器流道中的流量小,注水阶段不能保证出水管路满管流出水流,导致排气不畅,在集热器流道内存在“窝气”的问题,在出水管路上的排水阀门已经关闭的情况下,由于窝气的问题在集热器流道内的产生“窝气”的位置上不能注入水,而无法对该产生窝气的位置进行注水试压,若干该产生窝气的位置存在泄漏将无法被检查出来,大大降低了试压检漏的可靠性。4. The pressure test method using the vertical pressure test equipment of the traditional collector flow channel can only inject water into the collector flow channel through the pressurized pipeline. The flow rate input into the collector flow channel is small, and the outlet pipe cannot be guaranteed during the water injection stage. Water flows out of the full pipe, resulting in poor exhaust, and there is a problem of "cavity" in the flow channel of the collector. Water can not be injected into the position where the "cavity" is generated, and water injection and pressure test cannot be performed on the position where the gas is generated. Leakage in some positions where the gas should be generated will not be detected, which greatly reduces the cost of pressure testing and leak detection. reliability.
