　　We all know that manual hydraulic pumps have a certain service life, but in practical applications, it is found that sometimes some products cannot be used before the service period. In order to ensure the normal use of the product and improve the service life of the manual hydraulic pump, it is necessary to understand the daily maintenance and a series of measures need to be taken. How should we do it?

　　1. The frequency of use is another factor that affects the service life of the manual hydraulic pump of the mobile boarding bridge. We know of several uses of hand hydraulic pumps. The higher the frequency of use, the shorter the service life. The best way to solve this problem is to choose a manual hydraulic pump with better quality, long service life and low failure rate.

　　2. The hydraulic oil level in the hydraulic oil tank must be guaranteed. When the demand is compensated, the hydraulic oil grade is 10 aviation hydraulic oil. As the cam pushes the plunger up, the sealing volume of the plunger and cylinder decreases. When the cam rotates to the descending part of the curve, the tension spring forces the plunger down to create a certain degree of vacuum, and the oil in the tank enters the sealed volume under atmospheric pressure. The cam makes the plunger rise and fall continuously, the sealing volume decreases and increases periodically, and the pump continuously absorbs and discharges oil.

　　3. The seal of the manual hydraulic pump is greatly affected by temperature. Too high or too low temperature will affect the life of the manual hydraulic pump of the mobile boarding bridge, especially in areas with large temperature difference between day and night. The best way to reduce the impact of temperature on the service life of the manual hydraulic pump is to choose a manual hydraulic pump with better quality, and it is better to choose imported seals. At the same time, the seals must match the selected hydraulic oil.

　　4. During storage and use, attention should be paid to dust prevention. Ensuring the cleaning of hydraulic oil is a necessary condition to ensure the reliable operation of the electric pump and prolong its service life.

　　5. Load is also an important factor affecting the service life of the manual hydraulic pump. Generally, the load has little effect on the manual hydraulic pump. If the cylinder is not removed during operation, the seals of the cylinder and the manual hydraulic pump will be under pressure during the working process of the forklift. If the pressure is too high, the service life of the seals of the cylinder and the manual hydraulic pump will be reduced, so , mobile boarding b. Ridge in use, must follow the operating procedures.

　　6. Avoid repeated or prolonged contact with gasoline or breathing gasoline vapor to maintain good health. The manual hydraulic pump is one of the hydraulic pumps. Its function is to convert the mechanical energy of power engines (such as electric motors and internal combustion engines) into pressure energy of liquids. It is a two-stage hydraulic pump with a stepped plunger. As a hydraulic power source, in addition to broken objects, it can also be used in combination with other types of objects or experimental devices.
