(1) Check the plunger there is no scar and corrosion phenomenon, when necessary, should be replaced new.nt is a typical hydraulic machinery, driven by a prime mover, the input of mechanical energy is converted into fluid pressure energy, and then entered as pressure, flow into the system, it is the power source of the hydraulic system, because it can transport liquid under high pressure, so the industrial production and daily life in various industries have been widely used.Electric pump in the use of open air should turn the nut, turn the switch on the set of oil blocks, plug in the power, and set in the joint rapid equipped with hydraulic equipment rapid head. Press the power switch, rolling 1-2 minutes until the motor will switch into a closed pressurized state, the output will be the job of hydraulic oil, hydraulic oil output increases with the load and self-boost the work carried out until 63MPA .

?Diesel high-pressure pump high-pressure oil pump problems analysis is known as diesel "heart" is the diesel fuel supply system is the most important part, it's fundamental role is timing, quantitative supply for the high-pressure diesel injectors. Diesel high-pressure pump is not a normal job, working on all diesel has a crucial impact. Diesel engine can not start the diesel engine can not start the trouble can not reason is that low pressure oil to the high pressure fuel supply. 1, the oil in the air, to obstruct the fuel into the high-pressure pump oil chamber. Place a long time on a diesel engine, it is a normal appearance. Its approach is to release the high pressure pump bleed screw, hand pump to the high pressure pump oil, wipe clean the air, and then tighten the bleed screw. If effective, it is possible to loosen the filter pipe joints deflated, then bleed vent screw. 2. Low oil blocked, so no high pressure fuel pump low pressure oil chamber oil. The site of obstruction main pump oil inlet filters and filter elements, blocking reason is Dirty, attributed to normal skills situation changed, if found should immediately eliminate or replace. 3, the low-pressure pump to the high pressure fuel supply can not. Pump piston severe wear or damage, spring or other parts may cause damage to the appearance of such problems, identify the cause be replaced. 4, the high-pressure fuel supply pipeline or a road link portion severe leak. Check tubing connector is not loose and tubing is not damaged, loose to tighten, to replace damaged.
Our daily test axial piston pump, the press does not load, empty load test can be run properly, when we put the object, but no pressure can not operate, this phenomenon with the axial piston pump wear components are influences.
????Axial piston pump inside the port plate and the plunger, in the case of high-speed operation, the plunger and the cylinder with high clearance requirements, produce flow and pressure, if after a long run-in with the gap enlarged, it will cause internal leakage , which can not reach the corresponding flow and pressure; in addition, in the case of the port plate rotates at high speed, with the entry of the passage of time and impurities directly wear, then not produce pressure, flow generated directly through the gap and return port directly to tank vent.
Above it is an axial piston pump manufacturer to introduce you to factors that can not operate normally, hoping to help everyone better solution. When we experience this, be sure to check the wear of each part, timely check and replace, guaranteed to work properly.
Whether using a manual pump, or the use of other related products, no matter how high its quality, its use for some time, inevitably there will be some failures, large and small, which have an impact on our work, then In order to use a manual pump can proceed smoothly, how to prevent these failure it?
??????Xiao Bian for you on this issue, we first need to regularly check and replace aging or damaged oil seal or "O" ring sealing gasket; in addition to the manual replacement of worn hydraulic Gear Pump or pump bushings, wear light in flat end mill will be smooth. Its flatness tolerance 0.03mm; the end face of the sleeve is less than the plane manual pump body (normal is less than 2.5 ~ 2.6mm), such as ultra-poor should be the next sleeve plus 0.1 ~ 0.2mm copper to compensate for installation When put on the rear axle load should be set; if you can do these points compared with its applications will play help.
???????Jiangsu Hengli Hydraulic Co., Ltd. is specialized in producing electric hydraulic pumps and various hydraulic equipment business. Specializing in the production of high pressure electric pump, high pressure electric pump stations, high pressure hand pump stations and a variety of convenient and practical hydraulic tools. Large number of products exported abroad, by the majority of users praise. Enterprises adhere to the principle of quality first, the credibility of the first, the better to provide users with a variety of reliable hydraulic tools.
????Scientific management ideas, high-quality workforce, advanced processing equipment, perfect testing means is the company's product quality assurance.
Fuel pump, also known as high-pressure pump, the fuel system is a major component. Fuel pump function is progressive fuel pressure, and at the request of the diesel engine operating conditions, the amount of fuel injected into the combustion chamber within a precise time.
Piston pump is the pump in one, but the whole pump industry is a typical investment-driven industries, the market demand is subjected to national macroeconomic policies, which is subject to macroeconomic policy Teyou water, construction, energy and other sectors of greater impact. Hydraulic piston pump is a piston pump, the hydraulic industry's annual output value has not reached 10 billion yuan business, even more than 500 million yuan of annual output value of only a handful of companies, with total annual sales of the entire industry not as a of total sales. When supporting industries do not have the ability to compete with foreign companies, import goods on the domestic market will be strong artificial means of control and nothing to take into account. Most of the profits of construction machinery spare parts have been removed to the fact that not only allow the host manufacturer painful and helpless. Based on this situation, OEMs as well as funds from other industries are constantly entering the hydraulic industry. Just over one billion yuan investment into the hydraulic industry. But this trend is no doubt to increase the intensity of competition within the industry, changing the original industrial structure and order. Piston
