Product Description

Manual Hydraulic Pump Portable Hydraulic Equipment


Product information

Manual Hydraulic Pump Portable Hydraulic Equipment, the function of manual hydraulic pump is to convert the mechanical energy of power machine (such as motor and internal combustion engine) into the pressure energy of liquid.

How it works: the Portable Hydraulic Equipment Pump is driven by an electric motor.When the Portable Hydraulic Equipment pushes the plunger upward, the sealing volume formed by the plunger and the cylinder body decreases, and the oil is pushed out of the sealing volume through the one-way valve to the desired place.When the CAM rotates to the lower part of the curve, the spring forces the plunger down to a certain degree of vacuum, and the oil in the tank enters the sealing volume under the action of atmospheric pressure.The Manual Hydraulic Pump keeps the plunger up and down, the sealing volume decreases and increases periodically, and the pump keeps absorbing and discharging oil. Manual Hydraulic Pump Portable Hydraulic Equipment

As a simple and convenient hydraulic power source, uhv manual hydraulic pump is widely used in ship industry, coal mining machinery, petrochemical industry, metallurgy, electric power and heavy machinery.And with its small size, light weight, easy to carry, strong security and other advantages are accepted by the majority of users. Manual Hydraulic Pump Portable Hydraulic Equipment

MP series ultra-high pressure manual hydraulic pump, working pressure is 100~300MPa;Pressure relief valve is set inside the pump. In order to prevent pressure overload, safety release valve is also set inside the pump.Second level flow design, the displacement of first level low pressure is 33CC, and the displacement of second level high pressure is 1.6cc.Under constant power condition, low pressure and large flow oil supply, high pressure and small flow oil supply, saving time and improving efficiency.The external size is 585*120*170mm, and the total weight with oil is about 11Kg.It is proved that this kind of pump is convenient and flexible, low labor intensity and durable, and is an ideal ultra-high pressure hydraulic power source.

Maintenance

1. Find the fault reasons from the following three points during maintenance and improve the system:

1. Check the internal leakage of the boom cylinder:

The easiest way is to raise the arm and see if it has a significant free fall.Remove the cylinder if the drop is obvious, and replace the sealing ring if abrasion is found.

2. Check the control valve:

First clean the safety valve and check whether the valve core is worn or not. If worn, replace it.If there is no change after installation of the safety valve, then check the wear condition of the control valve core. Its clearance service limit is generally 0.06mm.

3. Measure the pressure of the hydraulic pump:

If the pressure is low, it can be adjusted. If the added pressure is still not adjustable, it indicates serious wear of the hydraulic pump.

2. The main reasons causing the failure of lifting arm belt load are:

1. Severe wear of hydraulic pump.Serious leakage in pump during low speed operation;When running at high speed, the pump pressure is slightly increased, but due to the wear and internal discharge of the pump, the volumetric efficiency is significantly decreased, so it is difficult to reach the rated pressure.Hydraulic pump to work long hours and contributed to the wear and high oil temperature rise, the resulting wear hydraulic components and seal aging, damage, loss of seal ability, hydraulic oil deterioration, resulting in failure.

2. Unreasonable selection of hydraulic components.The specification of the movable arm cylinder is 70/40 non-standard series, and the sealing parts are also non-standard parts.The small diameter of oil cylinder of moving arm will inevitably make the system set high pressure.

3. The design of hydraulic system is unreasonable.As can be seen from figure 1, the control valve is connected with the full hydraulic steering gear with a single pump, the pressure of the safety valve is set at 16MPa, and the rated working pressure of the hydraulic pump is also 16MPa.Hydraulic pump in full load or often work long time overload (high pressure) cases, and the system has a hydraulic impact, not an oil change for a long time, the hydraulic oil contamination, increase hydraulic pump wear and tear, so that the hydraulic pump shell burst (had found this kind of failure).
