Hand Opotrated Hydraulic Pump Pressure Instruments
Summarize
Hand Opotrated Hydraulic Pump Pressure Instruments, 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. Hand Opotrated Hydraulic Pump and with its small size, light weight, easy to carry, strong security and Other advantages are accepted by the majority of users. The existing Hydraulic Pump Pressure Instruments on the market is usually plunger pump, there are two types: single stage and double stage.All valves are usually concentrated on the plunger pump and are relatively compact.The reversing valve and plunger pump are divided into two independent parts, but can be used in combination.The structure of single-stage plunger pump is relatively simple.Two - stage plunger pump has two different structural forms.
Single stage plunger pump principle introduction
When the handle of single-stage single-stage plunger pump is lifted up, the hydraulic oil enters the lower cavity of the plunger through the filter and one-way valve, and the hydraulic pump absorbs the oil.The plunger provides oil to the system as the handle moves downward.The valve is the relief valve and the valve is the unloading valve.The single-stage pump is the intermittent pressurized oil supply, the displacement is not adjustable, only low pressure large flow or high pressure small flow;Generally low, medium Pressure Pump.
Introduction to the principle of two-stage plunger pump
Lift the handle and the hydraulic oil goes through the filter and one-way valve into the large and small cavity of the plunger respectively.When the handle is pressed down, there are two cases: when the system is at low pressure, the one-way valve is opened, and the two pumps simultaneously supply oil to the system, with the maximum flow.When the system is under high pressure, the sequence valve is opened (the pressure of the sequence valve is generally set at 1 MPa), the one-way valve is closed, the low-pressure oil of the large pump is directly returned to the tank, and the small pump supplies oil to the system separately, with a small flow rate.The valve is the constant pressure valve, and the valve is the unloading valve.Two-stage I manual pump for low pressure large flow high pressure small flow, intermittent oil supply.
The valve is the constant pressure valve, and the valve is the unloading valve.In the low pressure zone, when the handle moves upward, the lower oil chamber of the pump feeds oil, and the upper chamber of the pump supplies oil.When the handle 1 moves downward, the upper chamber of the pump feeds oil, and the lower chamber of the pump supplies oil to the system.The pump can supply oil continuously to the system in the low pressure area.When entering the high pressure zone, the pressure of the system increases, and the right position of the hydraulic control Directional valve works, so that the oil pipeline composed of pump and one-way valve is unloaded, and the oil pipeline composed of pump and one-way valve is used to supply oil to the system.Compared with the two-stage type II double-stage I, the two-stage II manual pump can realize continuous oil supply, which improves efficiency and saves time. However, it is also a low-pressure, high-flow, high-pressure and low-flow oil supply.
