The pressure test pump is actually a kind of testing equipment that provides high-pressure liquid for various pressure equipment, such as our common valves, water-heating boilers, etc., and the fire-fighting equipment we use to extinguish fires cannot be separated from it. It is made of stainless steel. Made of the same material, it has now been widely used in various industries, even in the aerospace industry. Because of its different uses, the pressure test pump is divided into electric pressure test pump and manual pressure test pump.

The electric pressure test pump is made of stainless steel and belongs to the reciprocating plunger pump. It is composed of several parts. The plunger is driven by the motor to work, thereby driving the slippage to increase the pressure. Due to the complex structure of the electric pressure test pump, everyone must pay attention when using it. The switch must be tightened clockwise. Secondly, its workplace is also required, and it cannot be used in occasions with acid, alkali or corrosive substances. , Besides, when it is no longer used, it must be filtered with kerosene or kerosene as a medium. The important point is that it cannot be loaded with water. As long as you do these points, you can ensure the normal operation of the electric pressure test pump. use.

The electric pressure tester is mainly suitable for hydraulic pressure test of various pressure vessels, oxygen cylinders, pipelines, valves, steam boilers, etc., new pre-stress processing technology and equipment for obtaining high-pressure liquid sources in the laboratory. It is a new series of products designed by the pressure test pump joint design group of the General Machinery Research Institute of the former Ministry of Machinery Industry. It has the characteristics of high "three modernizations" of the old products, long service life, stable performance, flexible movement, and light weight. On this basis, a transmission device and a cross conversion are added to make this series of products meet the requirements, with various performances more stable and reliable, safer and more convenient to use, and at the same time achieve the effect of energy saving and electricity saving. In the product structure, a closed water tank is selected, which reduces the height of the whole machine and makes the appearance more compact and beautiful. This product is specially designed based on 5°-60°C clear water, emulsion and oil with a viscosity not greater than 45mm2/s as the working medium. It can quickly fill and increase the pressure in the initial stage of pressure test to shorten the test time. , Has a larger flow rate, when the pressure exceeds 1.6Mpa (the pressure can be lowered), in order to make the pressure test process more stable, the flow rate will be automatically reduced. Therefore, the product has two flow rates at high and low pressures, and can automatically change. Any value pressure test can be carried out below the rated discharge pressure. The working environment temperature of this product: 5°-60°C.

1. Purpose

  The 4DSY type pressure automatic control electric pressure test pump is produced in accordance with the petrochemical general machinery standard JB/T9089-1999 of the Ministry of Machinery Industry. This pump is widely used in petroleum, chemical, mechanical construction and other industries. It can be used for sealing pressure test and strength test of various pressure vessels, boilers, plumbing and gas pipelines, valves, rubber and plastic pipe fittings, and mechanical parts. The test medium is 5°C-60°C clear water, emulsion or oil with sports index less than 45mm/s.

This series of pumps has the characteristics of stable working performance, high degree of three transformations, easy operation and maintenance, compact structure, flexible movement, etc., suitable for various construction sites and laboratories, and is an ideal pressure test equipment.

2. Equipment characteristics of the pressure pump 1. Using water or oil as the pressure test medium, it can realize the hydraulic test of different pressure levels between 35MPa and 280MPa. 2. The entire test process is automatically controlled by a computer, and all test settings and operations can be completed in the automatic console, or each valve can be manually controlled remotely to realize an unmanned site for pressure test. 3. The computer automatically generates pressure and time curves, displays them in real time, stores various data, and can print out inspection reports in Chinese and English at any time. 4. Monitor the test object, compress and save the video data during the whole process. 5. The double pressure relief device of computer automatic pressure relief and manual pressure relief is more safe and reliable. 6. The whole set of equipment has mature technology, and many companies have used it safely for many years. 7. The core components of the equipment are gas booster pumps and high-pressure valves. 8. The electrical control part follows the electrical industry, using industrial control computers and data acquisition cards, with stable control performance and true and reliable data.
