Electric Hydraulic Jack Oil Pump High Pressure
Product Overview:
The tensioning oil pump is a special equipment used to provide tensioning power for the prestressing jack when it is used for prestressing tension. The specification form of the equipment is ZB 2×2/50, where ZB is the equipment code, the first 2 is the rated oil supply per minute, the second 2 is the number of oil supply channels, and 50 is the rated oil pressure.
Electric Hydraulic Jack Oil Pump High Pressure Details
1.Electromagnetic valve control to with draw piston in any position.
2.High and low speed two stage design is for quick oil output. Turine oil absorption could ensure reaching Max. effective oil volume;
3.Over pressure safety valve unit could aviod over pressure damage. At 700kg/cm2, automatically release;
4.High pressure is for driving piston and low pressure is for piston reset.
5.Oil pipe fitted with quick coupling could be ordered for any length.

Pump system Self-priming axial piston pump, its working process is as follows
The motor drives the shaft to rotate. During the rotation of the shaft, the plunger is pressed into the plunger sleeve through the swash plate on the shaft, and the return spring relies on its elastic force to keep the plunger close to the thrust bearing surface at all times. The alternation of the shaft and the spring The effect is to make the plunger reciprocate in the plunger sleeve to achieve the purpose of oil suction and discharge so that the oil nozzle can obtain continuous and uniform pressure oil.
Control valve
The control valve is composed of two valve bodies with the same structure on the left and the right. The throttle valve is an adjustable cone valve, which can adjust the flow into the working cylinder by changing the size of the flow section of the valve gap. The unloading valve is a manual shut-off valve. Open the unloading valve, and the oil in the working cylinder can flow back to the oil tank.
The pressure sustaining valve is a one-way valve, which is used to cut off the refueling path of the high-pressure oil in the working cylinder of the jack, so as to ensure that the jack can hold the load without returning oil when it is parked or running dry.
The safety valve relies on the spring pressure to limit the higher pressure of the system, and the higher pressure of the system can be changed by adjusting the spring pressure, thus playing the role of safety protection.
Safety Precautions for Tension Oil Pump
1. The power supply wiring should be connected to the neutral line, and the insulation of each place should be checked at any time to avoid electric shock. When using it, the connection of the power line or the contact at the beginning should be checked frequently to prevent the motor from being burned due to lack of phase operation.
2. The oil pipes and joints should be manufactured according to the specifications and checked at any time to avoid bursting accidents. When the oil pump is under pressure, the joints, pipes, and oil gauges must not be disassembled.
3. The pressure gauge should be checked at any time to prevent accidents caused by failure.
4. The control valve should be opened before driving (no-load start). When using, check whether the pressure of the safety valve is adjusted properly, and always ensure that it is sensitive and reliable.
5. The bearings installed on the upper body should be replaced with lubricating oil in time according to the situation.
6. When the oil level is too low, do not work under pressure for a long time when the plane bearing in the pump body is exposed to the oil level.
