4D-SY pressure remote control automatic control electric pressure test pump
Pressure test pump | Electric pressure test pump | Pressure automatic control pressure test pump | Pressure automatic control remote pressure test pump
On the basis of the original series of electric pressure test pumps of our company, the electric contact pressure gauge pressure automatic control remote control system is added, and the pressure automatic control remote control system is upgraded and transformed into a pressure remote control automatic pressure test pump. After modification, the following functions can be achieved: Before the pump is used, only need to set the pressure value on the electric contact pressure gauge and then use the remote control to start the pressure test pump within a certain distance. When the pressure reaches the pre-set target value for the pressure test, The pressure test pump will automatically stop and enter the pressure holding state.
The 4D-SY type (6.3-80MPa) electric pressure test pump is mainly suitable for hydraulic pressure test of various pressure vessels, oxygen cylinders, pipelines, valves, steam boilers, etc., the new prestress processing technology and the high pressure source of liquid in the laboratory equipment. It is the latest 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. And on this basis, the transmission device and cross conversion are added, so that the comprehensive technical indicators of this series of products fully meet the standard requirements, various performances are more stable and reliable, and the use is safer and more convenient. At the same time, it achieves 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.
Technical parameter
There are seven types of pressure test pumps in this series. The basic parameters are shown in the table:

Low pressure cylinder plunger diameter: 45mm
Low pressure cylinder working pressure: ≤1.6MPa
Number of cylinders: 4
Plunger stroke: 40mm
Reciprocating times per minute: 51
When selecting a pressure test pump, the rated discharge pressure of the pump should be selected according to the required test pressure. The flow requirements should also be taken into consideration.
