Precautions for anchor pull gauge
. The hydraulic oil that should be used for this product is #anti-wear hydraulic oil, and the best use environment is ℃～ ℃. It is strictly prohibited to use alcohol, glycerin, brake oil, ordinary engine oil, etc. as hydraulic oil.
.The tool is rated for a maximum pressure of up to . In addition, in order to increase the service life of the pressure gauge, it is generally not used more than % of the maximum pressure.
.The joint parts of the oil pump and cylinder of this tool are subject to high pressure, so the joints must be protected and not damaged, which will affect the seal and normal operation. Do not use a wrench to pull the joint crimping part of the rubber hose to prevent the crimping part. Loose, causing oil leakage and scrapping of the hose.
.The oil barrel and pipeline of the tool should be cleaned frequently with clean kerosene to ensure the normal operation of the tool and extend its service life.
.Note: Do not block dirt in the inlets and outlets of each oil line. This product has a one-year warranty and free usage guidance for users.
Main technical parameters of anchor tension gauge:
. Maximum pulling force:
. Rated pressure:
. Piston stroke (plus return spring):
. Piston area: . Square centimeters
. Hand cranking force (reaching rated pressure): ㎏
. Weight: approx. ㎏.
Problems and solutions
.The pressure gauge does not show the pressure
There is no oil in the oil pump. Open the oil cylinder and inject the spindle oil.
Open the relief valve on the B pump clockwise. Tighten the relief valve
If there is oil leakage at the joints, tighten each joint
The oil pump is not placed in a horizontal position and then pressurize again after placing the oil pump flat
. The pressure gauge has pressure but it cannot reach the rated pressure
There is too little oil in the oil pump. Open the oil cylinder and inject the No. 1 spindle oil
There is oil leakage at the B joint and tighten each joint
Use the wrong oil and it is too dirty and clean it and then change the oil
Operating procedures for the anchor tension gauge :
Check the oil quantity: If the hydraulic cylinder piston does not fully retract into the cylinder, first connect it to the hand pump through the oil pipe, loosen the unloading valve on the pump body counterclockwise, and release the oil in the jack. The hydraulic oil drains back into the hand pump reservoir. Unscrew the oil filling valve and check the oil amount. If the oil is not full, add No. 1 wear-resistant hydraulic oil or No. 1 engine oil.
Exhaust: After the hydraulic system is assembled, air is often mixed in the oil storage cylinder, oil pipe and hydraulic cylinder. In order to make the hydraulic system normal, this air must be discharged. The method is to place the manual pump slightly higher than the hydraulic cylinder, press the manual pump to extend the piston of the hydraulic cylinder, and then open the unloading valve to retract the piston several times in a row. If necessary, open the oil filling valve to remove the air in the oil storage tank.
Detect the anchor: Connect the oil pipe to the jack, and check the oil volume, exhaust and pressure gauge according to the requirements of the above items. Screw the tie rod (please indicate the specifications when ordering or prepare your own according to the actual testing situation) to the end of the anchor rod. If the outer diameter of the inner thread of the tie rod is larger than the center hole of the oil cylinder, an extension sleeve can be added to the bottom of the oil cylinder and then put on the hydraulic cylinder (so that piston end outward), then tighten the nut and tighten the relief valve clockwise. Press the oil pump handle with even force and do not use excessive force. When the reading on the pressure gauge reaches the required level, stop pressurizing. Note that the hand pump must be placed horizontally to work. After the inspection is completed, the relief valve should be loosened in the opposite direction of the needle to make the pressure gauge read zero, and then all components should be removed from the anchor rod.
Overview of the anchor tension gauge:
. It is a testing tool for measuring the anchoring force of the anchor. It plays a significant role in the bolting and shotcrete support project, the research on various anchors, and the quality inspection of the project.
.The anchor tension gauge is composed of a manual oil pump, a high-pressure oil pipe, an oil cylinder, and a tie rod. It has the characteristics of small size, light weight, easy to carry, simple operation, and safety. It is widely used in coal, national defense, tunnels, and transportation, etc. Various construction sites. The manual two-speed oil pump can also be used alone as a power source to transport small flows of high-pressure oil. The oil cylinder can also be used as a jack.
