Fuel Valve Test Unit common faults and troubleshooting
Common faults and troubleshootingModel:HDP1100-D2(1) The pressure cannot be built up:1. Check whether the nut of the injector fixing screw is tight (compression nut).2. Check whether the test oil meets the hydraulic oil specified in this manual (replace the specified oil). 3. Check whether the filter is cleaned according to the specified time (replace and clean the oil filter). 4. Check whether the oil level of the fuel tank is too low (add test oil).(2) The test bench does not work: 1. Check whether the air pipeline connected to the test bench is unblocked (replace the joint and the air pipe). 2. Check whether the air pressure regulating valve (3) and the input air meter (6) have air pressure (replace the air pressure regulating valve).(3) Pressure leakage: 1. Check whether there is any leakage in the joints inside the test bench (tighten the joints).2. Check whether the oil return valve leaks (grind the oil return valve stem, replace the oil return valve). 3. Check the input and output joints of the high-pressure oil pump for oil return (disassemble the two joints to clean or replace the two inlet and outlet joints).(4) The pressure gauge does not return to zero when the pressure is zero: After the pressure on the test bench is completely released, adjust the "0-adj" knob at the back of the digital display to return to zero. Increase in clockwise direction and decrease in counterclockwise direction. (If there is no response, replace the pressure gauge and pressure sensor).(5) The digital display meter does not display: 1. Check the power input terminal of the digital display meter (terminal 1, 2 is 110VAC; terminal 1, 3 is 220VAC. Choose which group of inputs according to the situation on board, please consult the electrical engineer on board). 2. Check whether the input terminal has electricity, if there is electricity, it will not display (replace the digital display meter.) (6) Garbled characters on the digital display:If the replacement pressure sensor is still garbled, please replace the digital display.

Allison pneumatic hydraulic pump thick accumulation thin price down to the bottom 2019-08-08 10:43:14 Online: 2019-08-08 10:43:14 With the help of time and technology, the achievements made by the independent brands in the domestic market of pneumatic hydraulic pump and fuel injector in just a few decades are obvious to all in the shipping industry. First of all, they broke the monopoly of similar imported products from foreign countries. Second, it depresses prices and services. Such as small HQ150 pneumatic hydraulic pump. Domestic brands have always been the low-end route, because of Allison pneumatic hydraulic pump, cost-effective by the ship recognized. With the gradual improvement of Allerson's reputation in the shipping industry and the market demand. Allerson is constantly developing new products and innovating on old ones. Allerson pneumatic hydraulic pump thick accumulation of the price all the way down to the bottom. DetailHydraulic cylinder disassembly precautions
Hydraulic cylinders are commonly used in jacking operations. They are widely used jacking tools. Allison hydraulic cylinders are designed to operate at pressures ranging from 0-200 MPa. When we need to remove the hydraulic cylinder maintenance, some things must be paid attention to.First, telephone consultation by the factory, the factory's technical personnel for technical guidance.2. Care shall be taken to avoid contamination of the parts caused by the environment.3. Disassembled parts and components shall be covered with plastic sheets.IV. The disassembled parts shall be inspected. If there is any abnormality, they shall be repaired or replaced.Above for you to introduce a few hydraulic cylinder dismantling matters to pay attention to, I hope to help you. Allerson hydraulic cylinder shall pay attention to the disassembly method, to avoid improper operation caused by the damage of hydraulic cylinder parts resulting in irreparable consequences. DetailComprehensive destructive test for Ellison bolt tensioner
Objective: To test the compression capacity and load of the bolt tensioner.Test tools: AHP3500 pneumatic hydraulic pump, UHH300 high pressure tubing, ultra-high pressure quick connectorSpecification of bolt stretcher: M42 interchangeable bolt stretcher specific parameters see the drawing:Preparation before the test:Connect the pneumatic hydraulic pump with the bolt stretcher, and check whether the pipelines are well connected. In order to ensure the safety of the pipeline, 15M long high pressure oil pipe is used, and the safety plate is used.Test procedure: divided into three stepsStep 1: Press to design pressure and hold pressure for 10 minutes.The second step: press to 200MPa and then hold the pressure for 10 minutes.Step 3: press until the bolt tensioner leakage test is over.Do not try this experiment for non-professionals.
