Pressure testing machine generally includes a rack, and a quiet jacking block and a dynamic jacking block are arranged in rack, moves jacking block and an oil
Cylinder is connected, and oil cylinder is connected by oil pipe with the oil pump that an alternating current generator mutually drives, and drives dynamic jacking block in the piston of oil cylinder
When oil pump starting it is slower, therefore need to wait for a period of time rear pump or output pump oil can just enter in oil cylinder, then just initiation pressure try
It tests, the process efficiency is not high, need to waste certain time to wait, therefore need one kind can be with the pressure testing machine of quick start.
Utility model content
The purpose of the utility model is to provide a kind of pressure testing machines comprising upper jacking block, lower jacking block, oil cylinder, rack, oil
Pump, direct current generator, variable-speed controller；A fixed upper jacking block is connected at the top of the rack, the bottom of the rack is set
There is an oil cylinder, a lower jacking block is connected on the piston of the oil cylinder upward, the oil cylinder passes through oil pipe and an oil pump phase
Connection, the oil pump and a direct current generator are drivingly connected, and the direct current generator is connect with a variable-speed controller signal；
It is characterized by: the top surface of the oil cylinder is provided with several electromagnetic relays, the electromagnetic relay includes court
The dynamic iron core that the lower jacking block direction is stretched out is provided with coil in the lower jacking block, is nested with magnet in the upper jacking block.
Further the electromagnetic relay and the coil are connect with PCB control system.
When further working, the electromagnetic relay, which is powered, drives the dynamic iron core to contradict the lower jacking block.
A kind of pressure testing machine of the utility model, have it is following the utility model has the advantages that
When starting the pressure testing machine, the electromagnetic relay being arranged on oil cylinder is powered, so that the electromagnetism
Jacking block is mobile downward rapidly and contradicts with it for the dynamic iron core of relay, due to not reaching when the dynamic iron core contradicts the lower jacking block
To the maximum displacement of the dynamic iron core, therefore the dynamic iron core constantly will apply thrust to the lower jacking block, so that the lower top
Block can enter pressure testing working condition and apply pressure to product, while provided with magnet and in institute in the lower jacking block
It states and is provided with coil in jacking block, the coil can be made to generate magnetic field and to the magnetic by being powered to the coil
Iron is attracted, and further applies the power toward the upper jacking block direction to the lower jacking block, allow the lower jacking block faster
Ground enters pressure testing state, so that the starting time of pressure testing machine be greatly saved.
Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of existing pressure testing machine；
Attached drawing 2 is a kind of structural schematic diagram of pressure testing machine of the utility model；
Attached drawing 3 is another status architecture schematic diagram of Fig. 2；
Marking in attached drawing includes: 1- rack, the upper jacking block of 2-, 3- oil cylinder, jacking block under 4-, 5- oil pump, 6- direct current generator, and 7- becomes
Fast controller, 8- stroke cushion block, 9- test block, 10- oil cylinder, 11- dynamic iron core, 12 lower jacking blocks, the upper jacking block of 13-, 14- coil, 15- magnetic

Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, below with reference to embodiment and
Attached drawing is described in further detail the utility model product.
Attached drawing 2 is that dynamic iron core contradicts lower jacking block schematic diagram when electromagnetic relay is powered, and attached drawing 3 is that electromagnetic relay does not lead to
Schematic diagram when electric.
As shown in Figure 1-3, a kind of pressure testing machine comprising upper jacking block, lower jacking block, oil cylinder, rack, oil pump, direct current
Machine, variable-speed controller；A fixed upper jacking block is connected at the top of the rack, the bottom of the rack is equipped with an oil
Cylinder is connected with a lower jacking block on the piston of the oil cylinder upward, and the oil cylinder is connected by oil pipe with an oil pump, described
Oil pump and a direct current generator are drivingly connected, and the direct current generator is connect with a variable-speed controller signal；
It is characterized by: the top surface of the oil cylinder is provided with several electromagnetic relays, the electromagnetic relay includes court
The dynamic iron core that the lower jacking block direction is stretched out is provided with coil in the lower jacking block, is nested with magnet in the upper jacking block.Pass through
Above-mentioned electromagnetic relay is set, so that the dynamic iron core will be stretched out towards the lower jacking block when electromagnetic relay energization, due to
The maximum displacement of dynamic iron core is greater than the maximum distance of dynamic iron core and lower jacking block, therefore dynamic iron core will be pushed up in working condition under conflict
Block, so as to apply the thrust in jacking block direction upward to the lower jacking block, while can be with by being powered to the coil
So that the coil generates magnetic field and attracts the magnet, further the lower jacking block is applied toward the upper jacking block side
