Method: The temperature is allowed to be 0.1i/min.in, and the durability test is calculated according to 0.2mm/min.m.4,3. 4.3.5. Durability
JB5123-91
Under the action of 1.5 times the rated pressure, maintain the pressure for 5m, no external leakage and permanent deformation of parts are allowed, 4.3.5. Durability
Under the action of rated force, the speed shall not be less than 100mm/hour, the running speed shall not be less than 90% of the full stroke range, after running and reversing 20 times, the external and internal friction tests shall be carried out, the external friction shall not exceed the specified value, and the internal leakage shall not exceed the provisions of 9: the pressure test does not allow the external filter to deform permanently, 4.4. The surface must be chrome-plated, and the plating shall not have any residue and marks. 4. All parts must be inspected and qualified: purchased parts and cooperative parts must have a certificate of conformity before they can be assembled. All parts should be cleaned and lubricated before assembly.
4.6 The coordination table of the main elements such as cylinder capacity, efficiency, liveness, and falling direction is not allowed to have any mechanical conditions such as carbon. 4.7 The exposed non-machined surfaces of the cylinder that has passed the inspection shall be coated with anti-cooking paint. 5 Test methods and inspection rules
6.1 Before the material is pressed out, a factory test run shall be carried out. 5.2 If any of the following conditions are met, a product type test must be carried out. The number of products for the type test is stipulated to be three, one of which is subject to full-scale crown test, and the rest are subject to age performance test.

and all the faults are checked. For the test, only do the full stroke operation and reversing 20 times, and then measure the net stagnation outside the dense rod. The stator needs to be operated for a week, and the pressure is maintained for 10
MET respectively. ;In order to measure the blood pressure drop, the F test pressure maintenance test is carried out under the condition of measuring the working pressure. 501 energy oil is introduced into the car with a relatively strong and stable operation: h. In the station room under a certain pressure, the stroke is not less than the whole line. 2. It can be inspected and tested. The loss of the bubble is measured. The replacement process is kept in the form of a piece of film. The oil is not filled in the car. B. The process is not allowed to leak. 1. All parts must have water for a long time. The whole line should meet the requirements of the store. Long-term safety inspection. D2R ril.
