valve pressure test pump, leading the industry trend. Hebei Raoyang Hongyuan Machinery Co., Ltd. (Hebei Raoyang pressure test pump factory) is a high-tech enterprise in Hebei Province. Founded in 1978, it is a designated manufacturer of pressure test pumps of the former Ministry of machinery and electronics industry. The main operating pressure test pump series mainly include computer-controlled pressure test pump, high-pressure pneumatic pressure test pump, digital display control pressure test pump, remote control pressure test pump, electric pressure test pump, manual pressure test pump, etc. People usually don't know much about the types and materials of valve pressure testing pumps. What kinds of pressure testing pumps are there and what materials are they made of? Let's have a basic understanding of the types and materials of pressure testing pumps: pressure testing pumps are divided into three types: electric pressure testing pumps, manual pressure testing pumps, electric portable pressure testing pumps and human numerical control pressure testing pumps. The materials of valve pressure testing pumps can be stainless steel (SS316 or SS304), Cast iron it depends on the application of the pump. The normal use of 316 stainless steel in water industry and pharmaceutical applications, as the effect of stainless steel at high temperature. In order to minimize the use of energy and ensure correct matching, the pump works as expected, and the pumping station should be tested regularly. Individual large-scale applications that will deform the water supply of water pumps after a period of time are usually equipped with centrifugal pumps, which should be of high efficiency. They should be tested separately to ensure that they are in the appropriate range, and replaced or properly prepared

there are three pressure points to be done when the valve pressure test pump detects the pressure of general pressure vessels, pipelines, valves, etc. * points are the normal working pressure; The second point is * working pressure (generally called safety coefficient pressure). The electric pressure pump is usually 1.5 times the working pressure, and the third point is the burst pressure, which is usually more than 2.5 times the working pressure. However, in the actual detection process, the first two points are generally OK. Therefore, when selecting the high-pressure electric compressor, the high-pressure electric compressor with matching pressure is generally selected according to * working pressure. Since the pneumatic pressure test pump itself has a safety factor of 1.2 times, it is better that the working pressure of the selected valve pressure test pump * does not exceed 20% of the pressure detection point. Secondly, it is also crucial to select the flow of the pressure test pump according to the volume of the pressure vessel. If there is no hard regulation on the pressure rise speed, it is generally appropriate that the pressure test pump can raise the pressure to the detection value within 3 minutes. If the volume is relatively small, the flow of the pressure test pump should be controlled within a certain range, followed by external accumulator or buffer; If the container is relatively large, it can be equipped with a large flow pressure test pump with overflow valve to shorten the detection time. In addition, low-pressure water injection can be used, and the general pipeline pump can be used. The water injection pressure can reach about 0.5MPa. When the pressure is high, a small flow pressure test pump can be used, which can greatly reduce the purchase cost of equipment. That's because under a certain power, the broken test piece of the electric pressure pump will be tightly aligned to 1, which is inversely proportional to the pressure and flow. The higher the pressure, the greater the flow, and the larger the volume and purchase cost of the pressure test pump

1. Operation method of valve pressure test pump (1) loosen the red pressure regulating screw (1) adopt the Japanese Panasonic company to exchange servo driver and servo electromechanical button, plug in the power line to start the motor, check whether the machine has suction, then shut down, and connect all pipes as shown in the above figure. (2) Turn on the motor. When water flows out of the return pipe, tighten the pressure relief valve, and then slowly screw down the pressure adjustment knob until the reading on the pressure gauge meets the pressure requirements you need, and then tighten the locking plate to shut down. (3) Check whether the reading on the pressure gauge decreases at this time. If the reading does not decrease, it indicates that the pressure resistance of the tested container is good, otherwise, it indicates that there is a leak inside the container. (4) After completing the operation, loosen the pressure relief valve and pressure adjustment knob first, then remove all kinds of pipes in turn, and then turn on the motor to idle the machine for about half a minute to drain the residual water stains in the machine. (5) Wipe the surface of the machine with cotton cloth and store it in a cool and dry place for next use. 2. Precautions for valve pressure test pump (1) this machine has formed a joint team, which adopts open motor. When it works normally for a long time, the surface temperature of the motor shell can reach. C. This is normal. (2) There should be a certain distance between the host and the water tank to strictly prevent water stains from splashing into the motor and causing leakage and burning out the motor. (3) The working liquid used in this machine must be non corrosive, non crystalline and non solidification to copper and rubber, and the liquid must be clear and free of impurities. (4) It is strictly forbidden to operate the empty machine for a long time to prevent reducing the service life
