First, the conditions of use of equipment: 1, the device can be normally installed at the demand side of the case without having to increase the use of other facilities. 2, maneuvering time: 8 hours × 3 classes / day × 250 days / year = 6000 hours / year. 3, ambient temperature: -5 ℃ ~ 42 ℃. 4, the test medium: water at room temperature (the temperature is below 0 ℃, pressure test media should be antifreeze). 5, the design pressure: 15MPa. 6, test temperature: room temperature. 7, the pressure measurement accuracy: accuracy of 1.6. The system uses a 1.6 mechanical disc seismic electrical contacts. 8. Power: AC380 / 220V, 50Hz. 9. Altitude: ≤1500 meters. 10, the relative air humidity requirements: ≤70-90%. Second, the main features of this set of equipment with reference to customer technical requirements of non-standard production. Which referenced test pump to perform standard: JB / T9089-1999 test pump JB / T53194 electric test pump product quality grading GB-T9234-1997 motorized reciprocating pump reciprocating pump motor GBT 7784-2006 three test methods, product name Detailed technical parameters: 3D-SY1150 / 15MPa electric test pump detailed technical parameters: 3D-SY1150 / 15MPa electric test pump rated discharge pressure 15Mpa. Rated flow is 1150L / h, matching for power 7.5Kw General Motors. Dimensions and weight without special requirements. Supporting pressure gauge, safety valve pump meet the examination requirements. Fourth, the product control system Description: Remote-controlled inverter variable flow pressure system consists of: 3D-SY1150 / 15MPa pressure test electric pumps, pressure remote control automation systems, frequency control and distribution systems and equipment control box. Fifth, the device has the following features: a boost, pressure, frequency variable flow control, segmentation boost (manual remote gradient boost) the pump before use, just set on the electrical contacts. the lower pressure and dwell time set on time relay, then use the remote control to start the test pump within a certain distance, or press the start button to open the pump. In the course of the pressure test operator can arbitrarily change the test pump drive motor speed by twisting the knob according to the size of the measured volume of the hose, so as to achieve the purpose of regulating the flow and pressure test pump boost boost time. When the pressure reaches the pre-set target, test pump will automatically stop into the packing state, when the dwell time to, then the automatic alarm began to beep, open the manual pressure relief valve dismounted system (can be changed manually vent automatic pressure relief, the need to increase the cost of optional features), the test is completed. The device also has a remote control and manual start with pressure gradient boost function when needed segmented pressure test, test pump pressure reached only by manual remote control to control the test pump to start and stop when the preset pressure. Fully meet customer work process: intermittent operation, the pressure to stop a few seconds, and then pressure test requirements.
