Rupture painted "anaerobic" glue "epoxy" glue, "801" glue or "502" in a gum (glue length of about 2-3 times the length of the rupture site); with tape or canvas strip wound laminated type adhesive layer at 4-5 (each should be coated with glue); the wound tape at both ends of the draw canvas tied the knot; wait until solidification can be used after 15-20min. Transposition law: in the hydraulic system, the same passage of rubber hose whose specifications identical, but bear different oil. Many industries are now using to pump, as technology continues to improve, the pump is continually improving, and for the hydraulic pump, in fact, even if it works quickly, but for the use of life is still possible delay is no way to go , then the pump how to improve its service life it?

Since the pump is part of a plurality of component parts together, for the components in the mix when both need to be filtered, and the inside of the piston pump for the hydraulic system as well as the pump seal, plus the use of the piston, These are the need to be processed, only handle these things, we can bring help to the hydraulic system, it can greatly improve the service life. Here we give you introduce a hydraulic pump efficiency and the use of methods to improve life, is filtered .

Because the pump, because the pressure is to become the energy of its motion, when the hydraulic pressure up and down, it is necessary to carry out its surface and internal filter, to ensure piston pump running time will not be a problem, because the hydraulic pump There are tanks, it will be installed inside the oil, it will be consumed at run time to make these oil hydraulic system above the movement, which is necessary to ensure the cleanliness of oil, the last is to prevent dust from entering into the system, this It is very critical, because dust from entering the ring will lead to deterioration of the quality of their work time for the hydraulic problem arises, the question arises more, even if repaired, and will bring harm to the hydraulic itself, so these are For the hydraulic pump should be checked before doing every day.

I believe doing these things, after the pump to work in a maintenance, so its service life will be longer, to ensure the system work smoothly and efficiently when the axial piston pump discharge of oil missing cause and solution :

1) suction tube and filter infarction or too much resistance: should be promptly cleaned to relieve congestion.

2) suction pipe diameter is too small: the right to increase the diameter, so that the suction smooth.

3) Hydraulic oil tank is too low: check the oil, proper refueling.

4) not overflowing oil pump body, and some atmosphere: oil filling should exhaust the pump.

5) Mifengbuyan, have entered the atmosphere: Tighten related fittings.

6) wear between the piston and the cylinder bore or oil pan and the cylinder: should be converted to the touch, good touch.

7) hydraulic pump leak serious, constituting volume low power: proper correction of the hydraulic pump.

8) Return the plunger inadequate or can not return, causing the match between the cylinder block and oil pan is sealed: Department of center stretched spring cracking actions should be checked and converted center stretched spring.

9) variable organizational failures, not just the task of pleading: adjustment should be checked and corrected the error.

10) the oil pump inappropriate or inhale, sucking hard leak or within components: the temperature rise in accordance with the actual environment, select the appropriate fluid, adjacent to the fastening can leak.

11) The motor speed inadequate: to find out why, stop adjustment.

12) the oil viscosity is too large: real-time conversion proper viscosity oil.

With Common Rail fuel injection system as the representative of electronically controlled fuel injection technology can be implemented in any speed conditions of the high-pressure fuel injection, which is to improve the low engine speed, low-load conditions are particularly favorable performance. Since the maximum allowable is determined by the stiffness and tightness main components with high pressure pump injection pressure, thus greatly improve the high-pressure fuel injection pressure will encounter the problem of declining oil pump reliability, particularly oil pump plunger excessive leakage is difficult to establish higher fuel pressure problems arising. Several key technical issues for the common rail fuel system high-pressure pump design, conducted theoretical analysis, discusses how to solve the pump plunger excess leakage problems. In the relevant literature drew extensively on the basis of the composition of the high-pressure common rail fuel system, working principle,
