No negative supply equipment as a new secondary supply equipment in 1997, the company developed by three first success, 1998, since the market is constantly promotion and development. No negative supply equipment, land, water, and pollution-free, easy installation and maintenance etc. Advantage, make it become a pool of water, and replace traditional secondary supply equipment, in recent years the first-selected products market demand abrupt warming. Many factories realized that a product advantage and development potential, also scrambling to grab a slice, pursue maximum profits, lead to negative manufacturers in the nationwide "blossom".
According to not complete count, no negative pressure from the original manufacturer company, three more than ten years ago to 2004, currently has soared to more than thousands, and each manufacturer production scale, product technology and after-sales service, etc. Also
Sanli corporation is the earliest and largest and most powerful manufacturers, and has thousands of professional personnel and the world first-class automated production line and testing facilities, professional While many from other factories producing pumps, water or cabinet products without pressure, small over only a dozen manual mill production.
Although 2007 released by the ministry of construction implementation CJ/T 265-2007 "no negative supply equipment of urban construction industry recommendation (June 1, 2008, but many of the manufacturer still hold believes the so-called", "the standard production feasible, even according to the enterprise standard production, from this would cause in product standards and technical requirements (or technology), and practical application, etc.
For example, some manufacturer regardless of product quality, to pursue the biggest blindly commercial profits, causing many inferior products in the market, give users tap water and water safety of network has brought great. Others don't have aptitude, but as the production of products for the "negative" product, without running water after the installation of water pump straight pipe, water pipe pressure or inadequate supply pipeline produced water pump, caused by such phenomena, the influence of water users. Coupled with the low level on the market competition and irrational purchasing malignant environment, greatly disturbed the whole industry development, no negative pressure to present application status in great confusion products.
In order to regulate the market order of the products without pressure and safeguard the public interest and the relevant departments must increase the pressure on the market of product quality and performance without etc, make inspection on real innovation developed, which complies with the state standard and enterprise features, with high technical content and high quality of products, and can be effectively and popularized and applied to the protection of intellectual property rights, through careful examination of the manufacturer, to eliminate the source of technology, plagiarism technology intellectual property infringement.
Therefore, we want to enterprise scale, production conditions, technical strength, after-sale service, mandatory index for the main business projects manufacturer must supply products, so that we can guarantee the manufacturer's strength and the production of products and after-sales service of responsibility for matching, also be helpful for industry and development.
Finally still should play in the true sense "no suction pressure-free equipment technical committee, the industry association and jointly carried by the association for enterprise market rules, in order to safeguard the interests of the state, manufacturers and users, and ensure the sustainable development of the industry. Through the above measures, believe to negative industry development, the interests of consumers and intellectual property protection will produce positive aspects of meaning, can make no negative product application more scientific and more reasonable and more environmental protection, energy saving, and thus more truly benefit the masses.
